Description

本発明は、振動発生体によりパネル板などの板面から音声を空間内に発生させる音声発生装置に関する。   The present invention relates to a sound generator that generates sound in a space from a plate surface such as a panel plate by a vibration generator.

従来、テレビやCDラジカセなどの音声やマイク入力による任意の音源に接続し、入力された音声信号を振動に変換する振動発生体を有し、この振動発生体を、例えば絵画の額縁裏面などの任意の物体に貼り付けることにより、その物体から音声を発生させるスピーカ装置が存在した。   Conventionally, it has a vibration generator that is connected to an arbitrary sound source such as a TV or a CD radio cassette or input from a microphone, and converts the input audio signal into vibration. There has been a speaker device that generates sound from an object by pasting it on an arbitrary object.

これは、音源からの音声信号が、接続コードによって振動素子の駆動信号発生部に入力され、駆動信号に変換されて振動素子部に出力するようにしており、振動素子部は両面接着テープによって任意の、例えば額縁の裏面に固着され、振動によって被振動体である額縁部から音声を発生させるものである。   This is because an audio signal from a sound source is input to a drive signal generation unit of a vibration element by a connection cord, converted into a drive signal, and output to the vibration element unit. For example, it is fixed to the back surface of the frame, and a sound is generated from the frame portion which is a body to be vibrated by vibration.

There was a drawback. In addition, since the sound source and the main body of the vibration element drive signal generator are connected by wire, there is a problem in that the distance to the sound source is restricted, the connection cord needs to be processed, and the appearance is impaired.

本発明は上記事情を考慮してなされたものであり、振動発生体を任意の被振動体に取り付けできるとともにその固着作業を容易にし、また、振動発生体に対する音源の設置場所の制約を少なくして、外観も良好なものにして被振動体へ明瞭な音声を伝達できる音声発生装置を提供するものである。   The present invention has been made in consideration of the above circumstances, and can easily attach a vibration generator to an arbitrary vibration target, facilitate its fixing work, and reduce restrictions on the location of the sound source with respect to the vibration generator. In addition, the present invention provides a sound generator that has a good appearance and can transmit clear sound to a vibrating body.

A suction cup body that is integrally formed with a vibration transmitting member that has a surface that closely fits to one surface of the vibration generating body and has a tip projecting outward from the central portion, and has a peripheral edge that expands into a trumpet shape. By attaching the suction cup body to the body to be damped in a buffering manner, the vibration transmitting member abuts on the body surface of the vibration plate, and the vibration generated by the vibration generator is transmitted to the body to be generated to generate sound from the surface of the plate body.

以下、図面に基づき本発明の1実施形態について説明する。図1に示す音声発生装置(1)は、音源(2)からの音声信号が接続コード(3)によって送信部(4)に入力され、無線信号に変換されて、図2に示す被振動体である意匠パネル(5)の裏面に取り付けられた受信部(6)に入力されるものであり、受信部(6)で受信された無線信号は、再び音声信号に変換され、さらに振動素子駆動信号に変換されて振動発生体(7)に出力する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The sound generating device (1) shown in FIG. 1 has the sound signal from the sound source (2) input to the transmission unit (4) by the connection cord (3), converted into a radio signal, and the vibrating body shown in FIG. The radio signal received by the receiving unit (6) is converted again into an audio signal and further driven by a vibration element. It is converted into a signal and output to the vibration generator (7).

図3に斜視図、図4に図2のA−A線に沿う断面図で示すように、振動発生体(7)は、薄い金属基板の片面側に極薄肉の圧電セラミック板を貼り合わせた圧電振動素子からなって前記受信部(6)で受けた無線信号を受信回路部(8)における制御回路によって音声信号に変換し、この変換された音声信号を振動発生体(7)で振動に変換し、前記振動発生体(7)の一面と密着して実質上一体に形成した金属や硬質合成樹脂などの硬質体からなる振動伝達部材(9)を介して接触している意匠パネル(5)に伝達し音声として復元するものであり、方形のケース(10)の意匠パネル(5)への取付面の中央部に設けた透孔(10a)の裏面に緩衝材(11)を介して固着されている。   As shown in a perspective view in FIG. 3 and a cross-sectional view taken along line AA in FIG. 2 in FIG. 4, the vibration generator (7) has an extremely thin piezoelectric ceramic plate bonded to one side of a thin metal substrate. A radio signal composed of a piezoelectric vibration element and received by the receiving unit (6) is converted into an audio signal by a control circuit in the receiving circuit unit (8), and the converted audio signal is vibrated by a vibration generator (7). The design panel (5) which is in contact via a vibration transmitting member (9) made of a hard body such as a metal or a hard synthetic resin which is transformed and is in close contact with one surface of the vibration generating body (7) and is substantially integrally formed. ) And restored as sound, and the back surface of the through hole (10a) provided in the center of the mounting surface of the rectangular case (10) to the design panel (5) is provided with a cushioning material (11). It is fixed.

前記振動伝達部材(9)の先端は前記透孔(10a)から外方に数mm程度突出しており、その先端面には薄いゴム片(12)を貼り付けるとともに、圧電振動素子(7)の後方にはケース本体(10)側に固着した圧縮コイルバネ(13)を設けて前方への突出力を付勢している。   The tip of the vibration transmitting member (9) protrudes about several millimeters outward from the through hole (10a), and a thin rubber piece (12) is attached to the tip surface of the vibration transmitting member (9). A compression coil spring (13) fixed to the case body (10) side is provided at the rear side to urge the forward output.

前記透孔(10a)の両側における取付面には、前記振動伝達部材(9)と中心点が一直線上に位置するように吸盤(15)を所定間隔で配置しており、この吸盤(15)によってケース(10)を任意の被振動体である意匠パネル(5)に取り付け、振動発生体(7)を振動させることで意匠パネル(5)の面から音声を発生させるものである。   Suction cups (15) are arranged at predetermined intervals on the mounting surfaces on both sides of the through-hole (10a) so that the vibration transmission member (9) and the center point are positioned in a straight line. The case (10) is attached to the design panel (5), which is an arbitrary body to be vibrated, and the vibration generator (7) is vibrated to generate sound from the surface of the design panel (5).

前記振動伝達部材(9)と吸盤(15)(15)とからなる列の両側には間隔を形成して平行に柔軟材質からなる接着部材(16)(16)を固着している。この接着部材(16)は、自由状態における前記振動伝達部材(9)のケース取付面からの突出長以下の厚み寸法とするとともに、その外表面の接着剤層には離型紙(17)を貼り付けており、列状とした振動伝達部材(9)と吸盤(15)のみの固定によるケース(10)の傾きを防止するように支持するものであり、さらに吸盤(15)によるケース(10)の固定をおこなわない場合には、前記離型紙(17)を剥がして接着固定することでケース(10)を保持することができるようにしている。   Adhesive members (16) and (16) made of a flexible material are fixed in parallel on both sides of the vibration transmission member (9) and suction cups (15) and (15). The adhesive member (16) has a thickness dimension equal to or shorter than the protruding length of the vibration transmitting member (9) from the case mounting surface in a free state, and a release paper (17) is attached to the adhesive layer on the outer surface. It is attached to support the vibration transmission member (9) and the suction cup (15) in a row so as to prevent the case (10) from tilting, and the case (10) by the suction cup (15). When fixing is not performed, the case (10) can be held by peeling off the release paper (17) and fixing it.

上記のようにケース(10)を接着部材(16)によって接着固定する場合を考慮して、前記吸盤(15)はそのアーム軸(15a)の端部に設けた回転軸(15b)とケース(10)の軸孔との係合により回動可能としており、吸盤(15)を使用しない場合は、アーム軸(15a)を90度回動することにより、図3、4中に2点鎖線で示すように、吸盤(15)部分をケース側面の凹部(10b)に収納できるようにしている。   Considering the case where the case (10) is bonded and fixed by the adhesive member (16) as described above, the suction cup (15) has a rotating shaft (15b) provided at the end of its arm shaft (15a) and the case ( When the suction cup (15) is not used, the arm shaft (15a) can be turned 90 degrees so that it is indicated by a two-dot chain line in FIGS. As shown, the suction cup (15) portion can be stored in the recess (10b) on the side surface of the case.

上記構成による音声信号伝達の形態を説明する。図1に示すように、CDラジカセなどステレオ出力の音源(2)からの音声信号は、送信部(4)から受信部(6)に、例えば、発光部と受光部とからなる赤外線LEDを用いた方式で伝達され、受信回路部(8)における復調回路からモード切替スイッチ(18)によって圧電振動素子(7)に出力する信号を、左右いずれかのチャンネルモード、あるいは左右チャンネルをミックスしたモノラルモードに切り換えるようにしている。   The form of audio signal transmission with the above configuration will be described. As shown in FIG. 1, an audio signal from a stereo output sound source (2) such as a CD radio cassette is transmitted from a transmission unit (4) to a reception unit (6) using, for example, an infrared LED including a light emitting unit and a light receiving unit. Signal transmitted from the demodulating circuit in the receiving circuit unit (8) to the piezoelectric vibration element (7) by the mode changeover switch (18), either the left or right channel mode, or the monaural mode that mixes the left and right channels To switch to.

前記モード切換機能は、図2にその使用例を示すように、被振動体である意匠パネル(5)が単一の場合はモノラルモードで使用するが、被振動体が2つ以上あってステレオモードで使用する場合は、図5に示すように、各受信部(6a)(6b)の左右のチャンネルモードをそれぞれ左および右に切り換えて使用することにより、意匠パネル(5a)および(5b)の各板面からの音声でステレオ音場を得ることができる。   As shown in FIG. 2, the mode switching function is used in a mono mode when the design panel (5) which is a vibrating body is single, but there are two or more vibrating bodies and a stereo. When used in the mode, as shown in FIG. 5, the design panels (5a) and (5b) are obtained by switching the left and right channel modes of the receiving units (6a) and (6b) to left and right, respectively. A stereo sound field can be obtained with sound from each plate surface.

しかして、被振動体である意匠パネル(5)などに振動発生体(7)を取り付けるときは以下のようにする。すなわち、吸盤(15)を用いて取着する場合は、ケース(10)の取り付け面から突出している振動伝達部材(9)の両側に吸盤(15)を位置させ、この吸盤(15)を意匠パネル(5)裏面の適当な平面部に押し付けて固着する。   Therefore, when attaching the vibration generating body (7) to the design panel (5) or the like which is the body to be vibrated, the following is performed. That is, when mounting using the suction cup (15), the suction cup (15) is positioned on both sides of the vibration transmitting member (9) protruding from the mounting surface of the case (10), and the suction cup (15) is designed. The panel (5) is pressed against an appropriate flat part on the back side and fixed.

このとき、吸盤(15)は所定量押圧させる必要があるが、振動発生体(7)は圧縮コイルバネ(13)のバネ力に抗してケース(10)内に押し込むことができるため、図4に2点鎖線で示すように、吸盤(15)に対して充分な変位量により強固に固着できるとともに、振動伝達部材(9)を確実に被振動体(5)に接触させ、充分な振動伝達をおこなうことができる。   At this time, the suction cup (15) needs to be pressed by a predetermined amount, but the vibration generator (7) can be pushed into the case (10) against the spring force of the compression coil spring (13). As shown by the two-dot chain line in Fig. 2, it can be firmly fixed to the suction cup (15) with a sufficient amount of displacement, and the vibration transmitting member (9) can be securely brought into contact with the body to be vibrated (5) to sufficiently transmit the vibration. Can be done.

そして、振動伝達部材(9)の先端面には薄いゴム片(12)が貼り付けられているので、意匠パネル(5)と硬質の振動伝達部材(9)とが直接接触することによるビビリ音を防止することができるものであり、また、伝達された被振動体(5)の振動は、吸盤(15)の柔軟性や圧縮コイルバネ(13)の弾性によってケース(10)に伝達することを抑制するため、ケース(10)へ振動が伝達して、内部に収納されている電気部品などへ悪影響を及ぼすことを防ぐことができる。   And since the thin rubber piece (12) is affixed on the front end surface of the vibration transmission member (9), the chatter noise caused by the direct contact between the design panel (5) and the hard vibration transmission member (9). In addition, the transmitted vibration of the vibrating body (5) is transmitted to the case (10) by the flexibility of the suction cup (15) and the elasticity of the compression coil spring (13). In order to suppress, it can prevent that a vibration transmits to a case (10) and has a bad influence on the electrical component etc. which were accommodated in the inside.

そして、吸盤(15)ではなく、直接接着によって振動発生体(7)を意匠パネル(5)に取り付ける場合には、吸盤(15)部分を回動してケース側面の凹部(10b)に収納することで、接着部材(16)をケース(10)表面に突出させ、次いで、離型紙(17)を除去してパネル(5)面の所定部位に押し付けることで固着することができ、同時に振動伝達部材(9)の先端も確実に意匠パネル(5)面に接触するので、振動伝達を確かなものとして意匠パネル(5)から発生する音声の音量、音質を確かなものとすることができるものであり、且つ、吸盤(15)と接着部材(16)方式との2つの取り付け手段が互いに干渉することを防いで被振動体に応じた取り付け手段を選択することができる。   When the vibration generator (7) is attached to the design panel (5) by direct bonding instead of the suction cup (15), the suction cup (15) is rotated and stored in the recess (10b) on the side surface of the case. This allows the adhesive member (16) to protrude from the surface of the case (10), then removes the release paper (17) and presses it against a predetermined part of the panel (5) surface, and simultaneously transmits vibration. Since the tip of the member (9) also securely contacts the surface of the design panel (5), the sound volume and quality of the sound generated from the design panel (5) can be assured by ensuring vibration transmission. In addition, it is possible to select the attachment means corresponding to the vibrating body by preventing the two attachment means of the suction cup (15) and the adhesive member (16) method from interfering with each other.

なお、振動発生体は、前記実施例の圧電振動素子(7)に限らず、ボイスコイルとマグネットとヨークで構成したマグネットコイルの電磁振動アクチュエータ装置としてもよいものであり、また、振動発生体を収納したケース(10)の固定は前記吸盤(15)による保持に限るものではなく、取り付け対象である被振動体の厚みが比較的薄いものや鋼板製である場合などは磁石を利用した吸着方式により着脱自在に固着するようにしてもよい。   The vibration generator is not limited to the piezoelectric vibration element (7) of the above embodiment, but may be an electromagnetic vibration actuator device of a magnet coil composed of a voice coil, a magnet, and a yoke. Fixing the stored case (10) is not limited to the holding by the suction cup (15). If the vibrating object to be attached is relatively thin or made of steel plate, a suction method using a magnet May be detachably fixed.

次に、本発明の他の実施形態について説明する。図6に示すように、音源(2)からの音声信号を受信する受信部(26)に接続される前記実施例と同様の構成からなる振動発生体(27)は、軟質合成樹脂で形成された吸盤体(35)の中央の肉厚部(35a)に嵌入して固着されている。   Next, another embodiment of the present invention will be described. As shown in FIG. 6, the vibration generator (27) having the same configuration as that of the embodiment connected to the receiving unit (26) that receives the audio signal from the sound source (2) is formed of a soft synthetic resin. The suction cup body (35) is fitted and fixed to the central thick part (35a).

前記吸盤体(35)は、その周縁をラッパ状に拡開した吸盤部(35b)を形成するとともに、中央の肉厚部(35a)には硬質材である振動伝達部材(29)を複合射出成形などにより一体に形成している。振動伝達部材(29)は、振動発生体(27)の一面と密着する面を有し、先端を吸盤体の中央肉厚部(35a)から外方に突出させており、前記振動発生体(27)を肉厚部(35a)に嵌入して固定することで振動伝達部材(29)と面接触するように形成されている。   The suction cup body (35) forms a suction cup portion (35b) whose periphery is expanded in a trumpet shape, and a vibration transmission member (29), which is a hard material, is combined and injected into the central thick portion (35a). It is integrally formed by molding. The vibration transmission member (29) has a surface that is in close contact with one surface of the vibration generator (27), and has a tip protruding outward from the central thick part (35a) of the suction cup body, 27) is formed so as to be in surface contact with the vibration transmitting member (29) by being fitted and fixed in the thick part (35a).

(35c)は、中央肉厚部(35a)と吸盤部(35b)との連接部に形成した薄肉部であり、この薄肉部(35c)の吸収作用により、吸盤体(35)の被振動体である意匠パネル(25)への吸着とともに、振動伝達部材(29)のパネル(25)面への接触を確保するようにしている。   (35c) is a thin portion formed at the connecting portion between the central thick portion (35a) and the suction cup portion (35b), and the vibration body of the suction cup body (35) is absorbed by the thin portion (35c). In addition to the adsorption to the design panel (25), the contact of the vibration transmitting member (29) with the panel (25) surface is ensured.

そして、この吸盤体の吸盤部(35b)を被振動体である意匠パネル(25)の平板面に固着することで、吸盤体(35)の中央肉厚部(35a)に埋設された振動伝達部材(29)の先端が意匠パネル(25)面に当接するようにしており、この構成によって、振動発生体(27)による振動を被振動体(25)の板面に良好に伝達し、板体表面から音声を発生させるものであって、振動発生体(27)を吸盤状の取付部材(35)と実質的に一体化してコンパクトな構成にすることができ、被振動体(25)への取り付けをさらに容易にすることができる。   Then, by attaching the suction cup part (35b) of the suction cup body to the flat plate surface of the design panel (25) which is the vibrator, the vibration transmission embedded in the central thick part (35a) of the suction cup body (35) The tip of the member (29) is in contact with the surface of the design panel (25). With this configuration, the vibration generated by the vibration generating body (27) is transmitted well to the plate surface of the body to be vibrated (25). It generates sound from the surface of the body, and the vibration generator (27) can be substantially integrated with the suction cup-shaped mounting member (35) to make a compact configuration, and to the body to be vibrated (25). Can be further facilitated.
