　図３は、端末装置１の構成をさらに詳細に示すブロック図である。
　図３に示すように、端末装置１は、入出力部１１、制御部１２、アンテナ部１３、通信部１４及び復号部１５を含んで構成される。
　入出力部１１は、振動デバイス１６、切替部１１２、音声出力部１１３、押圧補正部１１４、押圧入力部１１５、位置検出部１９、及び位置入力部１１６を含んで構成される。 FIG. 3 is a block diagram showing the configuration of the terminal device 1 in more detail.
As illustrated in FIG. 3, the terminal device 1 includes an input / output unit 11, a control unit 12, an antenna unit 13, a communication unit 14, and a decoding unit 15.
The input / output unit 11 includes a vibration device 16, a switching unit 112, an audio output unit 113, a press correction unit 114, a press input unit 115, a position detection unit 19, and a position input unit 116.

　切替部１１２は、一例として、２極双投スイッチであって、接点Ａ、Ｂ及び可動切片Ｃを備える。切替制御部１２２から入力された切替信号に基づき、音声出力部１１３から入力された入力電気信号を、接点Ａ及び可動切片Ｃを経て振動デバイス１６に出力したり、振動デバイス１６から入力された電気信号を、可動切片Ｃ及び接点Ｂを経て押圧補正部１１４に出力したりする。
　切替部１１２は、入力された切替信号が音声出力部１１３からの入力電気信号を振動デバイス１６に出力することを表す場合、可動切片Ｃを接点Ａに倒す。この時、切替部１１２は、音声出力部１１３からの入力電気信号を振動デバイス１６に出力する。切替部１１２は、入力された切替信号が振動デバイス１６からの出力電気信号を押圧補正部１１４に入力することを表す場合、可動切片Ｃを接点Ｂに倒す。この時、切替部１１２は、振動デバイス１６からの出力電気信号を押圧補正部１１４に出力する。 As an example, the switching unit 112 is a two-pole double-throw switch, and includes contacts A and B and a movable piece C. Based on the switching signal input from the switching control unit 122, the input electrical signal input from the audio output unit 113 is output to the vibrating device 16 via the contact A and the movable segment C, or the electric signal input from the vibrating device 16. A signal is output to the pressure correction unit 114 via the movable segment C and the contact point B.
When the input switching signal indicates that the input electrical signal from the audio output unit 113 is output to the vibration device 16, the switching unit 112 tilts the movable segment C to the contact A. At this time, the switching unit 112 outputs the input electrical signal from the audio output unit 113 to the vibration device 16. When the input switching signal indicates that the output electrical signal from the vibration device 16 is input to the pressing correction unit 114, the switching unit 112 tilts the movable segment C to the contact point B. At this time, the switching unit 112 outputs the output electrical signal from the vibration device 16 to the pressing correction unit 114.

　音声出力部１１３は、復号部１５から入力された復号後の音声信号を出力電気信号として生成して切替部１１２に出力する。
　押圧補正部１１４は、切替部１１２からの出力電気信号より振動デバイス１６にかかる歪み（押圧力）の大きさを算出し、位置検出部１９からの振動パネル１８が操作入力を受け付けた位置を表す位置情報により補正を行い、押圧入力部１１５に出力する。 The audio output unit 113 generates the decoded audio signal input from the decoding unit 15 as an output electric signal and outputs the output electric signal to the switching unit 112.
The pressure correction unit 114 calculates the magnitude of distortion (pressing force) applied to the vibration device 16 from the output electrical signal from the switching unit 112, and represents the position where the vibration panel 18 from the position detection unit 19 has received an operation input. Correction is performed based on the position information, and output to the press input unit 115.

　押圧入力部１１５は、押圧補正部１１４より得られた振動パネル１８が操作入力を受け付けた位置での歪み（押圧力）を端末状態制御部１２３に出力する。
　位置入力部１１６は、位置検出部１９から入力された位置情報を端末状態制御部１２３に出力する。 The press input unit 115 outputs the distortion (pressing force) at the position where the vibration panel 18 received the operation input obtained from the press correction unit 114 to the terminal state control unit 123.
The position input unit 116 outputs the position information input from the position detection unit 19 to the terminal state control unit 123.

　制御部１２は、通信制御部１２１、切替制御部１２２、及び端末状態制御部１２３を含んで構成される。
　通信制御部１２１は端末状態制御部１２３の制御のもとで、端末装置１と他の装置（例えば、基地局装置）との間で行われる通信状態（例えば、通信開始要求、通信中、通信終了要求、等）、送受信されるデータの種類（例えば、音声、テキスト、等）を管理し、また制御する。通信制御部１２１は、通信状態及びデータの種類を表す制御情報／状態を通信部１４及び端末状態制御部１２３に出力する。 The control unit 12 includes a communication control unit 121, a switching control unit 122, and a terminal state control unit 123.
The communication control unit 121 is a communication state (for example, a communication start request, during communication, communication between the terminal device 1 and another device (for example, a base station device) under the control of the terminal state control unit 123. (End request, etc.) and the type of data to be transmitted / received (for example, voice, text, etc.) are managed and controlled. The communication control unit 121 outputs the control information / state indicating the communication state and the data type to the communication unit 14 and the terminal state control unit 123.

　切替制御部１２２は、端末状態制御部１２３から通知される指示に基づいて、端末装置１が音声再生を行うか、歪み（押圧力）入力を行うかの切り替えを切替部１１２に指示を行う。切替制御部１２２に通知された指示は、端末状態制御部１２３が、通信制御部１２１から入力された制御情報／状態等を判断したものである。
　例えば、通信制御部１２１の状態が音声通話状態であると端末制御部１２３に通知された場合は、端末状態制御部１２３の指示により、切替制御部１２２から切替部１１２に音声出力部２１３からの出力電気信号を振動デバイス１６に出力するように切替信号を出力する。
　一方で端末状態制御部１２３にて上記の音声通話状態以外で振動パネルからの歪み（押圧力）を入力したい場合には、端末状態制御部１２３の指示により、切替制御部１２２から切替部１１２に振動デバイス１６からの出力電気信号を押圧補正部１１４に出力するように切替信号を生成する。 The switching control unit 122 instructs the switching unit 112 to switch whether the terminal device 1 performs audio reproduction or performs distortion (pressing force) input based on the instruction notified from the terminal state control unit 123. The instruction notified to the switching control unit 122 is one in which the terminal state control unit 123 determines the control information / state input from the communication control unit 121.
For example, when the terminal control unit 123 is notified that the state of the communication control unit 121 is the voice call state, the switching control unit 122 sends the switching unit 112 to the switching unit 112 according to the instruction from the terminal state control unit 123. A switching signal is output so that the output electrical signal is output to the vibration device 16.
On the other hand, when it is desired to input distortion (pressing force) from the vibration panel in the terminal state control unit 123 other than the voice call state described above, the switching control unit 122 changes the switching unit 112 according to the instruction of the terminal state control unit 123. A switching signal is generated so that the output electric signal from the vibration device 16 is output to the pressing correction unit 114.

　端末状態制御部１２３は、位置入力部１１６や押圧入力部１１５から入力された操作入力信号に基づいて端末装置１の動作を制御する。
　例えば、ここには図示されていない端末の表示部が利用者に対して選択対象の機能名を表す複数の文字列のリストを表示している場合について説明をする。即ち、位置入力部１１６において位置入力信号によりその文字が表示されている位置が選択され、押圧入力部１１５において、押圧入力信号が予め定めた閾値を越える押圧を示す場合である。
　このとき、端末状態制御部１２３は、その文字列に対応する機能名が選択されたと判断し、その選択された機能名に対する機能を起動する。 The terminal state control unit 123 controls the operation of the terminal device 1 based on the operation input signal input from the position input unit 116 or the press input unit 115.
For example, a case where a display unit of a terminal not shown here displays a list of a plurality of character strings representing function names to be selected for the user will be described. That is, the position input unit 116 selects the position where the character is displayed based on the position input signal, and the press input unit 115 indicates that the press input signal indicates a press exceeding a predetermined threshold.
At this time, the terminal state control unit 123 determines that the function name corresponding to the character string has been selected, and activates the function corresponding to the selected function name.

　アンテナ部１３は、他の装置（例えば、基地局装置）から受信した無線帯域信号を通信部１４に入力する。
　通信部１４は、アンテナ部１３から入力された無線帯域信号をダウンコンバートして基底帯域信号を生成する。通信部１４は、通信制御部１２１から入力された制御情報が、通信状態が通信中であって、データの種類が音声であることを示す場合、生成した基底帯域信号を復調して復調後の音声信号を生成する。通信部１４は、復調後の音声信号を復号部１５に出力する。
　復号部１５は、通信部１４から入力された復調後の音声信号を、符号化の際に用いた符号化方式に対応する復号方式を用いて、復号して、復号後の音声信号を生成する。復号部１５は、復号後の音声信号を音声出力部１１３に出力する。 The antenna unit 13 inputs a radio band signal received from another device (for example, a base station device) to the communication unit 14.
The communication unit 14 downconverts the radio band signal input from the antenna unit 13 to generate a baseband signal. When the control information input from the communication control unit 121 indicates that the communication state is in communication and the data type is voice, the communication unit 14 demodulates the generated baseband signal and performs demodulation. Generate an audio signal. The communication unit 14 outputs the demodulated audio signal to the decoding unit 15.
The decoding unit 15 decodes the demodulated audio signal input from the communication unit 14 using a decoding method corresponding to the encoding method used at the time of encoding, and generates a decoded audio signal. . The decoding unit 15 outputs the decoded audio signal to the audio output unit 113.

This sectional view represents a section taken along line BB 'in FIG. In FIG. 6, the horizontal direction represents the left-right direction, and the vertical direction represents the front-back direction.

As shown in FIG. 10, the terminal device 1 includes the display unit 17.
The transparent position detection unit 19 is provided on the back surface of the vibration panel 18 as in the terminal device 1 of FIG. 2, but the region is limited to the same region as the surface of the display unit 17 as shown in FIG. 10. Also good. The position detection unit 19 detects the position where the finger is in contact with the vibration panel 18. A combination of the transparent vibration panel 18, the transparent position detection unit 19, and the display unit 17 is, for example, a touch panel liquid crystal surface of a mobile terminal. Accordingly, it is possible to detect the presence or absence of contact with the vibration panel 18 and the touched position corresponding to the position of the image content displayed on the display unit 17. Other configurations, block diagrams, and input / output processing flows may be the same as those constituting the terminal device 1 of FIG.

　このように、本実施形態では、入力電気信号を変換した振動を振動パネル１８（タッチパネル液晶面）に伝達し、振動パネル１８から伝達された押圧力を出力電気信号に変換する振動デバイス１６を備える。振動デバイス１６は本実施形態では、一般的な携帯電話機のレシーバの位置付近に配置することにより、音声再生時に耳の近くで振動パネル１８がより大きな振幅で振動するようになるために効率よく音声再生を行う事が出来る。また、携帯電話のレシーバ位置は通常、タッチパネル液晶面の上部に配置されているためにタッチパネル液晶面を覆う透明の保護板を振動パネル１８として用いる事により効率的な構成にする事が出来る。
　また、本実施形態では、音声再生を行うか否かを指示する切替信号に基づいて、入力電気信号を入力されるか出力電気信号を出力するかを切り替える。これにより、本実施形態による入出力部１１は、１個の振動デバイス１６で音声再生又は押圧検出を使い分けることができ、更に振動パネル１８は液晶タッチパネル部も兼ねているために端末装置１を小型化、軽量化することができる。また、本実施形態による入出力部１１は、上述のように簡単な構成であるため、製造が容易である。 As described above, in this embodiment, the vibration device 16 that transmits the vibration obtained by converting the input electric signal to the vibration panel 18 (touch panel liquid crystal surface) and converts the pressing force transmitted from the vibration panel 18 into the output electric signal is provided. . In this embodiment, the vibration device 16 is arranged near the position of the receiver of a general mobile phone, so that the vibration panel 18 vibrates with a larger amplitude near the ear during sound reproduction, so that the sound can be efficiently generated. You can play it. In addition, since the receiver position of the mobile phone is usually disposed above the touch panel liquid crystal surface, an efficient configuration can be achieved by using a transparent protective plate covering the touch panel liquid crystal surface as the vibration panel 18.

FIG. 12 is a perspective view of the vibration device 26 according to the present embodiment.
FIG. 13 is a cross-sectional view of the vibrating device 26 according to the present embodiment, and is a cross-sectional view showing a cross section passing through a line corresponding to the line BB ′ in FIG.
FIG. 14 is a cross-sectional view of the vibration device 26 according to the present embodiment, and is a cross-sectional view illustrating a cross section perpendicular to the front and back direction of the vibration device 26 of FIG. 12.
Note that the piezoelectric element 261-2 and the electrodes 262-2-1, 262-2-2 are directly above the piezoelectric element 261-1 and the electrodes 262-1-1, 261-2, respectively. Does not appear.

　振動デバイス２６は、振動素子２６－１（第１の振動素子）、振動素子２６－２（第２の振動素子）及びモールド１６３を含んで構成される。
　振動素子２６－１、２６－２は、モールド１６３に覆われている。振動素子２６－１、２６－２は第１の実施形態における振動素子１６－１と同様にそれぞれ、圧電素子２６１－１ならびに電極２６２－１－１、２６２－１－２、圧電素子２６１－２ならびに電極２６２－２－１、２６２－２－２を含んで構成される。圧電素子２６１－１と圧電素子２６１－２は上下方向に並べて配置されているが、モールド１６３で離間されている。モールド１６３の材質は第１の実施形態におけるモールド１６３の材質と同じである。 The vibration device 26 includes a vibration element 26-1 (first vibration element), a vibration element 26-2 (second vibration element), and a mold 163.
The vibration elements 26-1 and 26-2 are covered with a mold 163. The vibrating elements 26-1 and 26-2 are respectively the piezoelectric element 261-1, the electrodes 262-1, 261-2, and the piezoelectric element 261-2, similarly to the vibrating element 16-1 in the first embodiment. And electrodes 262-2-1, 262-2. The piezoelectric element 261-1 and the piezoelectric element 261-2 are arranged side by side in the vertical direction, but are separated by a mold 163. The material of the mold 163 is the same as the material of the mold 163 in the first embodiment.

　電極２６２－１－１、２６２－１－２は、それぞれ圧電素子２６１－１の右端の表面及び裏面に装着されている。
　電極２６２－１－１、２６２－１－２は、音声出力部２１３から入力された入力電気信号の電位差を圧電素子２６１－１の表面及び裏面に供給する。これにより、圧電素子２６２－１は振動を発生させる。 The electrodes 262-1 and 262-1-2 are mounted on the front and back surfaces of the right end of the piezoelectric element 261-1, respectively.
The electrodes 262-1 and 262-1-2 supply the potential difference of the input electrical signal input from the audio output unit 213 to the front and back surfaces of the piezoelectric element 261-1. As a result, the piezoelectric element 262-1 generates vibration.

　電極２６２－２－１、２６２－２－２は、それぞれ圧電素子２６１－２の右端の表面及び裏面に装着されている。
　電極２６２－２－１、２６２－２－２は、切替部１１２から入力された入力電気信号の電位差を圧電素子２６１－２の表面及び裏面に供給する。これにより、圧電素子２６２－２は振動を発生させる。電極２６２－２－１、２６２－２－２は、圧電素子２６１－２が振動することによって生じた電位差を出力電気信号として切替部１１２に出力する。 The electrodes 262-1 and 262-2-2 are attached to the front and back surfaces of the right end of the piezoelectric element 261-2, respectively.
The electrodes 262-1 and 262-2-2 supply the potential difference of the input electric signal input from the switching unit 112 to the front surface and the back surface of the piezoelectric element 261-2. As a result, the piezoelectric element 262-2 generates vibration. The electrodes 262-1, 262-2-2 output the potential difference generated by the vibration of the piezoelectric element 261-2 to the switching unit 112 as an output electric signal.

　ここで、切替部１１２に入力された切替信号が音声出力部１１３からの入力電気信号を振動素子２６－２に出力することを表す場合、振動素子２６－１、２６－２は、ともに振動を発生させて振動パネル１８を振動させる。このとき、振動素子２６－１が発生させる振動と、振動素子２６－２が発生させる振動は同期しているため、両者の振動が重畳して、結果として振動が強調される。
　他方、切替部１１２に入力された切替信号が振動素子２６－２からの出力電気信号を押圧補正部１１４に入力することを表す場合、振動素子２６－２は、振動素子２６－２に加えられた押圧力に基づく出力電気信号を切替部１１２に出力する。押圧補正部１１４は、切替部１１２から入力された前記出力電気信号より振動素子１６－２にかかる歪み（押圧力）の大きさを算出し、位置検出部１９からの振動パネル１８に触れた位置を表す位置情報により補正を行い、押圧入力部１１５に出力する。 Here, when the switching signal input to the switching unit 112 represents that the input electrical signal from the audio output unit 113 is output to the vibration element 26-2, the vibration elements 26-1 and 26-2 both vibrate. The vibration panel 18 is vibrated. At this time, since the vibration generated by the vibration element 26-1 and the vibration generated by the vibration element 26-2 are synchronized, both vibrations are superimposed, and as a result, the vibration is emphasized.
On the other hand, when the switching signal input to the switching unit 112 indicates that the output electric signal from the vibration element 26-2 is input to the pressing correction unit 114, the vibration element 26-2 is added to the vibration element 26-2. An output electrical signal based on the pressing force is output to the switching unit 112. The pressing correction unit 114 calculates the magnitude of distortion (pressing force) applied to the vibration element 16-2 from the output electric signal input from the switching unit 112, and the position touched the vibration panel 18 from the position detection unit 19 Is corrected by the position information representing the position and output to the press input unit 115.

　このように、本実施形態では、振動デバイス２６は、入力電気信号を変換した振動を振動パネル１８に伝達する振動素子２６－１と、振動パネル１８から伝達された歪み（押圧力）を前記出力電気信号に変換する振動素子２６－２を備える。これにより、音声再生と操作入力を同時に実現することができる。
　また、切替部１１２は、切替信号に基づいて振動素子２６－２から入力電気信号を入力されるか、振動素子２６－２へ出力電気信号を出力するかを切り替える。これにより、利用者は、振動素子２６－１、２６－２両者による音声再生と、音声再生ならびに歪み（押圧力）入力の併用とを使い分けることができる。大音量で再生したい場合は前者の様に切替部１１２を切り替える事により、振動パネル１８の振動が強調されるため音量を増加させることができる。一方、低音量で再生したい場合には後者の様に切替部１１２を切り替える事により、音声再生には振動素子２６－１（半分の大きさの振動素子）のみを駆動させて効率よく再生するように構成出来るために消費電力を節減することができる。 As described above, in this embodiment, the vibration device 26 outputs the vibration element 26-1 that transmits the vibration converted from the input electric signal to the vibration panel 18 and the distortion (pressing force) transmitted from the vibration panel 18 as the output. A vibration element 26-2 for converting into an electric signal is provided. Thereby, voice reproduction and operation input can be realized simultaneously.
Further, the switching unit 112 switches whether to input an input electrical signal from the vibration element 26-2 or to output an output electrical signal to the vibration element 26-2 based on the switching signal. Thus, the user can properly use the sound reproduction by both the vibration elements 26-1 and 26-2 and the combined use of sound reproduction and distortion (pressing force) input. When it is desired to reproduce at a high volume, the switching unit 112 is switched as in the former, so that the vibration of the vibration panel 18 is emphasized, so that the volume can be increased. On the other hand, when it is desired to reproduce at a low volume, the switching unit 112 is switched as in the latter so that only the vibration element 26-1 (a vibration element having a half size) is driven for sound reproduction. Therefore, power consumption can be reduced.

（第３の実施形態）
　次に、本発明の第３の実施形態について説明する。
　本実施形態は、振動パネル１８に接触された位置を表す位置情報を検知し、振動デバイス１６の出力電気信号より検知できる振動デバイス１６にかかる歪み（押圧力）の大きさを、前記の検知した位置情報に基づいて補正し、振動パネル１８に接触した部分の歪み（押圧力）情報を算出することを特徴とする。 (Third embodiment)
Next, a third embodiment of the present invention will be described.
In the present embodiment, position information representing a position in contact with the vibration panel 18 is detected, and the magnitude of distortion (pressing force) applied to the vibration device 16 that can be detected from the output electric signal of the vibration device 16 is detected as described above. Correction is performed based on the position information, and distortion (pressing force) information of a portion in contact with the vibration panel 18 is calculated.

　本実施形態に係る端末装置３は、図１及び図２に示す端末装置１と同様の外観を有する。端末装置３の内部構成も、図３に示す端末装置１の内部構成と同様である。 The terminal device 3 according to the present embodiment has the same appearance as the terminal device 1 shown in FIGS. The internal configuration of the terminal device 3 is the same as the internal configuration of the terminal device 1 shown in FIG.

　押圧補正部１１４は、切替部１１２から入力された出力電気信号より振動デバイス１６にかかる歪み（押圧力）の大きさを算出し、位置検出部１９からの振動パネル１８が操作入力を受け付けた位置を表す位置情報により補正を行い、押圧入力部１１５に出力する。
　押圧入力部１１５は、押圧補正部１１４より得られた振動パネル１８が操作入力を受け付けた位置での歪み（押圧力）を端末状態制御部１２３に出力する。 The pressure correction unit 114 calculates the magnitude of distortion (pressing force) applied to the vibration device 16 from the output electrical signal input from the switching unit 112, and the position at which the vibration panel 18 from the position detection unit 19 has received an operation input. Is corrected by the position information representing the position and output to the press input unit 115.
The press input unit 115 outputs the distortion (pressing force) at the position where the vibration panel 18 received the operation input obtained from the press correction unit 114 to the terminal state control unit 123.

　次に、押圧補正部１１４が行う押圧値の補正処理について説明する。
　図１５は、本実施形態に係る押圧補正部１１４が行う押圧値の補正処理を表すフローチャートである。
（ステップＳ２０１）押圧補正部１１４は、切替部１１２から入力された電気信号より振動デバイス１６にかかる歪み（押圧力）の大きさを算出する。その後、ステップＳ２０２に進む。
（ステップＳ２０２）押圧検出部１１４に位置検出部１９から位置情報が入力される。その後、ステップＳ２０３に進む。
（ステップＳ２０３）押圧検出部１１４は、位置検出部１９から入力された位置情報が表す位置から振動デバイス１６の位置との間の距離を算出する。当該距離を算出するために、押圧補正部１１４には、振動デバイス１６の中心位置を表す位置から位置検出部１９が示す位置情報値に対する距離値が予め記憶されている。その後、ステップＳ２０４に進む。 Next, the correction process of the press value which the press correction part 114 performs is demonstrated.
FIG. 15 is a flowchart illustrating the correction process of the pressing value performed by the pressing correction unit 114 according to the present embodiment.
(Step S <b> 201) The pressing correction unit 114 calculates the magnitude of distortion (pressing force) applied to the vibration device 16 from the electrical signal input from the switching unit 112. Thereafter, the process proceeds to step S202.
(Step S <b> 202) Position information is input from the position detection unit 19 to the press detection unit 114. Thereafter, the process proceeds to step S203.
(Step S <b> 203) The press detection unit 114 calculates the distance between the position represented by the position information input from the position detection unit 19 and the position of the vibration device 16. In order to calculate the distance, the pressure correction unit 114 stores in advance a distance value from the position representing the center position of the vibration device 16 to the position information value indicated by the position detection unit 19. Thereafter, the process proceeds to step S204.

（ステップＳ２０４）押圧補正部１１４は、算出した距離ｒに基づいて補正量Ｌ（ｒ）を決定する。例えば、補正量Ｌ（ｒ）をa×ｒ２と算出する。ここで、ａは、予め設定された実数である。これにより、距離ｒの２乗に反比例する振幅の減衰を補正することができる。
　押圧補正部１１４は、その他の例として、自部が備える記憶部から位置検出部から入力される位置情報（ｘ、ｙ）に対応する補正量Ｌ（ｘ、ｙ）を読み出すようにしてもよい。
　記憶部には、位置検出部１９から入力される位置情報（ｘ、ｙ）のそれぞれに対して、その端末装置において実測した補正量Ｌ（ｘ、ｙ）を予め記憶しておく。位置情報（ｘ、ｙ）と補正量Ｌ（ｘ、ｙ）の対応関係を表す押圧補正情報の例については後述する。その後、ステップＳ２０５に進む。 (Step S204) The pressing correction unit 114 determines the correction amount L (r) based on the calculated distance r. For example, the correction amount L (r) is calculated as a × r 2 . Here, a is a preset real number. Thereby, the attenuation of the amplitude inversely proportional to the square of the distance r can be corrected.
As another example, the pressing correction unit 114 may read the correction amount L (x, y) corresponding to the position information (x, y) input from the position detection unit from the storage unit included in the pressing correction unit 114. .
In the storage unit, the correction amount L (x, y) actually measured in the terminal device is stored in advance for each piece of position information (x, y) input from the position detection unit 19. An example of the press correction information indicating the correspondence relationship between the position information (x, y) and the correction amount L (x, y) will be described later. Thereafter, the process proceeds to step S205.

（ステップＳ２０５）押圧補正部１１４は、決定した補正量Ｌを切替部１１２から入力された電気信号より振動デバイス１６にかかる歪み（押圧力）の大きさに乗じて補正後の押圧値を算出する。その後、処理を終了する。
　これにより、振動デバイス１６からの距離が長くなっても、振動パネル１８に触れた位置の歪み（押圧力）の大きさを知ることができる。従って、端末装置１は、操作の有無に限らず押圧の大きさによって動作態様を制御する手がかりを取得することができる。 (Step S205) The pressing correction unit 114 calculates the corrected pressing value by multiplying the determined correction amount L by the magnitude of distortion (pressing force) applied to the vibrating device 16 from the electrical signal input from the switching unit 112. . Thereafter, the process ends.
Thereby, even if the distance from the vibration device 16 becomes long, the magnitude | size of the distortion (pressing force) of the position which touched the vibration panel 18 can be known. Accordingly, the terminal device 1 can acquire a clue for controlling the operation mode according to the magnitude of the pressure, not limited to the presence or absence of the operation.

　次に、押圧補正情報の一例について説明する。
　図１６は、振動パネル１８が操作入力を受け付けた座標（ｘ、ｙ）とその位置から振動デバイス１６の中心までの距離ｒの関係の一例を表す図である。また、図１７と図１８は、それぞれ記憶部に記憶された押圧補正情報の例を示す図である。
　図１７において、左列は距離ｒを表し、右列は補正量Ｌを表す。例えば座標１の場合は距離ｒ＝２００に対して補正量Ｌは４００であり、座標２の場合は距離ｒ＝４０に対して補正量Ｌは１６００である。
　図１８において、左列は位置情報（ｘ、ｙ）を表し、右列は補正量Ｌを表す。例えば座標１の場合は位置情報（ｘ１,ｙ１）に対して補正量Ｌは４００であり、座標２の場合は位置情報(ｘ２,ｙ２)に対して補正量Ｌは１６００である。 Next, an example of the press correction information will be described.
FIG. 16 is a diagram illustrating an example of the relationship between the coordinates (x, y) at which the vibration panel 18 receives an operation input and the distance r from the position to the center of the vibration device 16. FIGS. 17 and 18 are diagrams illustrating examples of the press correction information stored in the storage unit.
In FIG. 17, the left column represents the distance r, and the right column represents the correction amount L. For example, in the case of coordinate 1, the correction amount L is 400 with respect to the distance r = 200, and in the case of coordinate 2, the correction amount L is 1600 with respect to the distance r = 40.
In FIG. 18, the left column represents position information (x, y), and the right column represents the correction amount L. For example, in the case of coordinate 1, the correction amount L is 400 for the position information (x1, y1), and in the case of coordinate 2, the correction amount L is 1600 for the position information (x2, y2).

　このように、本実施形態では、出力電気信号と位置情報に基づき振動パネル１８に接触した押圧情報を算出する。これにより、利用者が操作した位置による差異を排除して、操作によって生じた押圧値を正しく取得することができる。 As described above, in the present embodiment, the press information in contact with the vibration panel 18 is calculated based on the output electric signal and the position information. Thereby, the difference by the position which the user operated can be excluded, and the press value produced by operation can be acquired correctly.

　上述では、端末装置１、２又は３が通信機能を有する入出力装置であり、受話音声を再生する場合を例にとって説明したが、本実施形態ではこれには限られない。本実施形態では、端末装置１、２又は３は、音声再生機能と操作入力機能を備えた電子機器であればよい。 In the above description, the terminal device 1, 2 or 3 is an input / output device having a communication function and the received voice is reproduced as an example, but the present embodiment is not limited to this. In the present embodiment, the terminal device 1, 2 or 3 may be an electronic device having a sound reproduction function and an operation input function.

　上述の通信機能を有する入出力装置では、端末状態制御部１２３が通信制御部１２１からの情報を元に端末装置１、２又は３が、音声再生を行うか、操作入力を行うかを判断し、切替部１１２が音声出力部１１３からの出力電気信号を振動デバイス１６に出力することを表す切替信号又は振動デバイス１６からの入力電気信号を押圧補正部１１４に入力することを表す切替信号を切替制御部１２２が、生成する例について説明した。上述した実施形態の音声再生機能と操作入力機能を備えた電子機器では、端末状態制御部１２３が端末装置１、２又は３が、音声再生を行うか否かを判断し、音声再生を行うと判断したときに切替部１１２が音声出力部１１３からの出力電気信号を振動デバイス１６に出力することを表す切替信号を切替制御部１２２が、生成してもよい。その場合、切替部１１２は、入力された切替信号が音声再生を表すか否かにより可動切片ＣをＡに倒すか、Ｂに倒すかを制御するようにしてもよい。 In the input / output device having the communication function described above, the terminal state control unit 123 determines whether the terminal device 1, 2, or 3 performs audio reproduction or operation input based on information from the communication control unit 121. The switching signal indicating that the switching unit 112 outputs the output electrical signal from the audio output unit 113 to the vibration device 16 or the switching signal indicating that the input electrical signal from the vibration device 16 is input to the pressing correction unit 114 is switched. The example which the control part 122 produces | generates was demonstrated. In the electronic device having the sound reproduction function and the operation input function of the above-described embodiment, when the terminal state control unit 123 determines whether the terminal device 1, 2 or 3 performs sound reproduction and performs sound reproduction. The switching control unit 122 may generate a switching signal indicating that the switching unit 112 outputs the output electrical signal from the audio output unit 113 to the vibrating device 16 when it is determined. In that case, the switching unit 112 may control whether the movable segment C is tilted to A or B depending on whether or not the input switching signal indicates sound reproduction.

　図１９は、その一つの形態に係る端末装置４の構成を表すブロック図である。
　この形態に係る端末装置４は、音声再生部３１、音声データ蓄積部３２、音声再生制御部１２５を更に含んで構成されている。音声データ蓄積部３２は予め端末装置４に組み込まれた音声データや、無線通信手段や外部記憶媒体、端末付属のマイクロホン等を通して収録した音声データを蓄積する部分である。利用者の操作入力を受け付けて、端末状態制御部１２３が各種音声データの再生を指示した場合は、その指示を音声再生制御部１２５を経由して音声再生部３１に伝達する。音声再生部３１は、音声データ蓄積部３２に蓄積された音声データの中から指示された音声データを読み出す。音声再生部３１は読み出した音声データを音声出力部１１３に出力して、音声を再生する。 FIG. 19 is a block diagram showing the configuration of the terminal device 4 according to one embodiment.
The terminal device 4 according to this embodiment further includes an audio playback unit 31, an audio data storage unit 32, and an audio playback control unit 125. The voice data storage unit 32 is a part for storing voice data previously incorporated in the terminal device 4 and voice data recorded through a wireless communication means, an external storage medium, a microphone attached to the terminal, or the like. When the user's operation input is received and the terminal state control unit 123 instructs the reproduction of various audio data, the instruction is transmitted to the audio reproduction unit 31 via the audio reproduction control unit 125. The audio reproduction unit 31 reads out the instructed audio data from the audio data stored in the audio data storage unit 32. The audio reproduction unit 31 outputs the read audio data to the audio output unit 113 to reproduce the audio.

　また、図１９に示す端末装置４は、音声データを出力電気信号として振動デバイス１６、振動パネル１８を振動させる構成を備えるが、出力電気信号の周波数が、人間が振動を知覚する周波数（例えば、５－２０Ｈｚ）であってもよい。そこで、上記構成において音声データ蓄積部２２において音声データの代わりに、例えば、その周波数帯域を含む振動パターンのデータを蓄積しておく事により、振動パネル１８の振動により利用者にその事を通知する事が可能となる。この振動パターンは、例えば、携帯電話の着信バイブレータや、タッチパッド／タッチパネル操作時に操作を受け付けた事を利用者に知らせるためのフォースフィードバックに用いられるものである。
　これにより、本実施形態による入出力部１１は、１個の振動デバイス１６で振動による通知又は押圧検出を使い分けることができ、端末装置４を小型化、軽量化することができる。また、本実施形態による入出力部１１は、上述のように簡単な構成であるため、容易に製造することができる。 The terminal device 4 shown in FIG. 19 includes a configuration in which the vibration device 16 and the vibration panel 18 are vibrated using audio data as an output electric signal. The frequency of the output electric signal is a frequency at which a human perceives vibration (for example, 5-20 Hz). Therefore, in the above configuration, instead of the voice data, for example, by storing the vibration pattern data including the frequency band in the voice data storage unit 22, the user is notified of the vibration by the vibration of the vibration panel 18. Things will be possible. This vibration pattern is used for, for example, a mobile phone incoming vibrator or force feedback for notifying the user that an operation has been accepted when operating the touch pad / touch panel.
Thereby, the input / output unit 11 according to the present embodiment can selectively use vibration notification or pressure detection with one vibration device 16, and the terminal device 4 can be reduced in size and weight. Moreover, since the input / output unit 11 according to the present embodiment has a simple configuration as described above, it can be easily manufactured.

　上述の端末装置２又は３では、入出力部２１が、振動素子２６－２と押圧補正部１１４もしくは音声出力部２１３との入出力を制御する切替部１１２を備える場合を例にとって説明したが、本実施形態ではこれには限られない。本実施形態では、入出力部２１が、振動素子２６－１と押圧補正部１１４もしくは音声出力部２１３との入出力を制御する切替部１１２を備えてもよい。 In the terminal device 2 or 3 described above, an example in which the input / output unit 21 includes the switching unit 112 that controls input / output between the vibration element 26-2 and the press correction unit 114 or the audio output unit 213 is described. This embodiment is not limited to this. In the present embodiment, the input / output unit 21 may include a switching unit 112 that controls input / output between the vibration element 26-1 and the pressure correction unit 114 or the audio output unit 213.

　上述では、振動デバイス２６が２個の振動素子２６－１、２６－２を備える場合を例にとって説明したが、本実施形態ではこれには限られない。本実施形態では、振動デバイス２６は、３個以上の複数の振動素子を備えてもよい。複数の振動素子のうち、少なくとも１個以上の振動素子が押圧補正部１１４もしくは音声出力部２１３との入出力を制御する切替部１１２を備えてもよい。 In the above description, the case where the vibration device 26 includes the two vibration elements 26-1 and 26-2 has been described as an example, but the present embodiment is not limited thereto. In the present embodiment, the vibration device 26 may include three or more vibration elements. Among the plurality of vibration elements, at least one vibration element may include a switching unit 112 that controls input / output to / from the pressing correction unit 114 or the audio output unit 213.

　上述の入出力部２１において、切替部１１２から入力される出力電気信号から回り込み成分を差し引いて入力除去信号を生成し、押圧補正部１１４は生成した入力除去信号を入力されるようにしてもよい。回り込み成分とは、入力電気信号に基づいて発生し振動パネル１８に伝達された振動を振動素子２６－２が生成する出力電気信号に寄与する成分である。入出力部２１は、例えば、図２０の端末装置５に示すように第２切替部５１２、回り込み合成部５１３及び減算部５１４をさらに備えてもよい。 In the input / output unit 21 described above, an input removal signal may be generated by subtracting the wraparound component from the output electrical signal input from the switching unit 112, and the pressure correction unit 114 may be input with the generated input removal signal. . The wraparound component is a component that contributes to an output electrical signal generated by the vibration element 26-2 that generates vibrations based on an input electrical signal and is transmitted to the vibration panel 18. The input / output unit 21 may further include, for example, a second switching unit 512, a wraparound combining unit 513, and a subtracting unit 514 as illustrated in the terminal device 5 of FIG.

　第２切替部５１２は、切替部１１２と同様に、切替制御部１２２から切替信号を入力され、音声出力部２１３から入力電気信号を入力される。但し、入力された切替信号が音声出力部２１３からの出力電気信号を振動素子２６－２に出力することを表す場合、第２切替部５１２は、入力された入力電気信号を回り込み合成部５１３に出力する。入力された切替信号が振動素子２６－２からの入力電気信号を押圧出力部１１４に入力することを表す場合、第２切替部５１２は、入力された入力電気信号を遮断する。 As with the switching unit 112, the second switching unit 512 receives a switching signal from the switching control unit 122 and an input electrical signal from the audio output unit 213. However, when the input switching signal indicates that the output electric signal from the audio output unit 213 is output to the vibration element 26-2, the second switching unit 512 wraps the input electric signal into the synthesizing unit 513. Output. When the input switching signal indicates that the input electric signal from the vibration element 26-2 is input to the pressing output unit 114, the second switching unit 512 blocks the input electric signal.

　回り込み合成部５１３は、第２切替部５１２から入力された入力電気信号に基づき、回り込み成分信号を合成する。ここで、例えば、操作入力がなされない状態で出力電気信号として得られた回り込み成分と、入力電気信号に基づいて回り込み特性係数を予め算出しておく。算出した回り込み特性係数を回り込み合成部５１３に設定しておく。回り込み合成部５１３は、入力された入力電気信号に対して設定された回り込み特性係数でフィルタリングして回り込み成分信号を生成する。回り込み合成部５１３は、合成した回り込み成分信号を減算部５１４に出力する。
　減算部５１４は、切替部１１２から入力された出力電気信号から回り込み合成部５１３から入力された回り込み成分信号を減算して回り込み除去信号を生成する。減算部は、生成した回り込み除去信号を押圧補正部１１４に出力する。 The sneak synthesizer 513 synthesizes the sneak component signal based on the input electrical signal input from the second switching unit 512. Here, for example, a sneak characteristic coefficient is calculated in advance based on a sneak component obtained as an output electrical signal when no operation input is made, and the input electrical signal. The calculated sneak characteristic coefficient is set in the sneak synthesis unit 513. The sneak synthesis unit 513 generates a sneak component signal by filtering with the sneak characteristic coefficient set for the inputted input electric signal. The sneak synthesis unit 513 outputs the synthesized sneak component signal to the subtraction unit 514.
The subtraction unit 514 subtracts the sneak component signal input from the sneak synthesis unit 513 from the output electrical signal input from the switching unit 112 to generate a sneak removal signal. The subtracting unit outputs the generated wraparound removal signal to the press correcting unit 114.

　その他、本実施形態では、切替部１１２と押圧増幅部１１４に音声帯域の成分（例えば、２００Ｈｚ－４．０ｋＨｚ）を除去するフィルタを備えてもよい。
　これにより、本実施形態では、音声再生と操作入力が同時に行われる場合に、再生された音声に基づく振動による成分が誤って押圧として取得されることが回避される。 In addition, in the present embodiment, the switching unit 112 and the pressure amplification unit 114 may be provided with a filter that removes an audio band component (for example, 200 Hz to 4.0 kHz).
Thereby, in this embodiment, when audio | voice reproduction | regeneration and operation input are performed simultaneously, it is avoided that the component by the vibration based on the reproduced | regenerated audio | voice is acquired accidentally as a press.
