When there is an incoming call, the control unit 15 causes the auxiliary sound output unit 17 to output a ringtone.

Thus, according to the configuration of this example, the control unit 15 issues an alarm for calling attention to the auxiliary sound output unit 17 before a relatively loud sound is output from the main sound output unit 8. Since the announcement is output, the operator's ear can be surely protected from the unexpectedly large volume, and the operator can surely hear the sound as the information to be alarmed.
That is, for example, when the downloaded music is to be reproduced and output, the first low volume portion is not missed as in the prior art in which the volume is gradually increased.

This example is greatly different from the first embodiment described above in that a relatively short alarm announcement is repeatedly output.
Since the other configuration is substantially the same as the configuration of the first embodiment described above, the description thereof will be simplified.
In this example, the control unit 15 of the mobile phone 1 replaces a relatively long message such as “Please make the mobile phone 1 20 cm or more away from the ear. If a relatively short message such as “Sound is heard” or “Large volume attention” is repeatedly output to the auxiliary audio output unit 17 and output a predetermined number of repetitions, the main audio is a voice or music in the speaker mode. Output to the output unit 8.

According to the configuration of this example, it is possible to obtain substantially the same effect as that of the first embodiment described above.
In addition, the operator can be surely grasped the alarm contents without missing the alarm announcement.

This example is greatly different from the first embodiment described above in that the alarm of vibration is added by vibrating the diaphragm of the main audio output unit at a relatively low frequency simultaneously with the output of the alarm announcement.
Since the other configuration is substantially the same as the configuration of the first embodiment described above, the description thereof is omitted.
In this example, the control unit 15 functions as a vibration generation control unit and causes the auxiliary audio output unit 17 to output an alarm announcement, and at the same time, causes the diaphragm 26 of the main audio output unit 8 serving as a vibration unit to have a predetermined vibration. Vibrate with a pattern.

According to the configuration of this example, it is possible to obtain substantially the same effect as that of the first embodiment described above.
In addition, since the alarm can be transmitted by vibration, the operator can be surely grasped the alarm content.

In the storage unit 38, various registers and flags used by the control unit 37 when executing the program are secured.

  In the audio output control processing program, when an audio output request is received, a procedure for determining whether or not the audio output is in speaker mode, and in speaker mode, after switching to the receiver mode, an alarm announcement is made. In the audio output unit 32, a procedure for determining whether or not a predetermined grace period has elapsed since the start of alarm announcement output, and a speaker mode when it is determined that a predetermined grace period has elapsed. And a procedure for outputting a predetermined music piece and sound to the sound output unit 32 is described.

Next, a mobile phone 1A of this example will be described with reference to FIG.
When the operator P opens the housing 26 and executes, for example, a program (such as a moving image file with audio) downloaded from the site, when the operation unit 42 is operated, the control unit 37 receives a program execution request, It is determined whether or not a voice output request is included (step SB11 (FIG. 8)).
If the control unit 37 determines that the request includes an audio output request, the control unit 37 then determines whether the audio output is in the speaker mode (step SB12). If the mode is the speaker mode, the process proceeds to step SB13. If the mode is the receiver mode, the process proceeds to step SB17.

Next, in step SB13, the control unit 37 switches to the receiver mode, and in step SB14, for example, an alarm announcement such as “Please make a mobile phone 20 cm or more away from your ear. The piezoelectric drive unit 33 is driven and controlled so as to be output to the unit 32.
Next, the control unit 37 determines whether or not a predetermined grace period necessary for releasing the mobile phone 1A from the ear portion R has elapsed since the output of the alarm announcement was started (step SB15).
When the control unit 37 determines that the predetermined grace period has elapsed, the control unit 37 switches to the speaker mode (step SB16), executes, for example, a moving image file stored in the storage unit 38, and controls the piezoelectric drive unit 33 to perform audio. A predetermined voice or music is output to the output unit 32 (step SB17), and an image (moving image) is displayed on the display unit.

Here, the control unit 37 controls the piezoelectric drive unit 33 so that the amplified drive signal is supplied to the actuator module. The actuator module receives the amplified drive signal, converts the drive signal as an electrical signal into an acoustic signal, and vibrates the diaphragm. Sound waves are directly emitted from the diaphragm. The operator P can see the display screen of the display unit 34.
Note that, for example, not only when a program (such as a moving image file with sound) downloaded from a site is executed but also when a mail reading function is used, sound is emitted from the diaphragm.

According to the configuration of this example, the control unit 37 causes the audio output unit 32 to output an alarm announcement for calling attention before a relatively loud sound is output from the audio output unit 32. It is possible to reliably protect the operator's ear from an unexpectedly large volume, and to reliably hear sound as information to be alarmed.
That is, for example, when the downloaded music is to be reproduced and output, the first low volume portion is not missed as in the prior art in which the volume is gradually increased.
Further, since the warning announcement is output at a relatively low volume, the operator is not uncomfortable or uncomfortable.
Moreover, since the auxiliary sound output unit 17 and the auxiliary speaker driving unit 18 are eliminated, it is possible to further contribute to the reduction in size, weight, and cost of the device.

FIG. 9 is a processing procedure diagram for explaining the operation of the mobile phone according to the fifth embodiment of the present invention.
This example is greatly different from the fourth embodiment described above in that a warning message is issued when an incoming call is received in addition to the request from the operator.
Since the other configuration is substantially the same as the configuration of the fourth embodiment described above, the description thereof will be simplified.
A voice output control processing program is stored in the storage unit 38 of the cellular phone 1A of this example. The voice output control processing program determines whether or not voice output processing is being performed when it is detected that there is an incoming call. And a procedure for determining whether or not the sound is being output in the speaker mode when the sound output processing is in progress; a procedure for switching to the receiver mode and outputting the alarm announcement to the sound output unit 32 in the speaker mode; A procedure for determining whether or not a predetermined grace period has elapsed since the start of the alarm announcement output, and switching to speaker mode and outputting a ring tone to the auxiliary output unit 32 when it is determined that a predetermined grace period has elapsed. The procedure to be performed is described.

Next, a mobile phone 1A of this example will be described with reference to FIG.
After the power is turned on, the control unit 37 of the cellular phone 1A in this example enters a standby mode for waiting for an input operation or an incoming call by the operator. The control unit 37 monitors whether or not there is an incoming call (step SC11 (FIG. 9)), and if it is detected that there is an incoming call, whether or not the voice output process is in progress, that is, the voice output unit 32 currently outputs a voice. It is determined whether or not (step SC12). During the voice output process, for example, when the operator holds the mobile phone 1A at the call position and a message message is output from the voice output unit 32, the process proceeds to step SC13. The process proceeds to step SC18.

In step SC13, it is determined whether or not the speaker mode is output. If the speaker mode is selected, the process proceeds to step SC14. If the receiver mode is selected, the process proceeds to step SC15.
At step SC14, the receiver mode is switched to, and at step SC15, for example, an alarm announcement such as "Please make a mobile phone 20cm or more away from your ear. The piezoelectric drive unit 33 is driven and controlled.

Next, the control unit 37 determines whether or not a predetermined grace period necessary for releasing the mobile phone 1A from the ear portion R has elapsed since the output of the alarm announcement was started (step SC16).
If the control unit 37 determines that a predetermined grace period has elapsed, the control unit 37 switches to the speaker mode (step SC17), controls the piezoelectric drive unit 33, and causes the voice output unit 32 to output a ring tone (step SC18). In addition, the control unit 37 controls the light emitting unit 35 to cause the LED to emit light and notify an incoming call.

Next, when the call start key of the operation unit 42 is pressed, the control unit 37 causes the audio output unit 32 to stop outputting the ringtone and starts the call process (step SC19). Output from the audio output unit 32.
That is, the control unit 37 controls the piezoelectric drive unit 33 so that the amplified drive signal is supplied to the actuator module. The actuator module receives the amplified drive signal, converts the drive signal as an electrical signal into an acoustic signal and vibrates the diaphragm, and sound waves are directly emitted from the diaphragm.
The operator P can hear a received voice at the call position and speak to the transmitter 43 to make a call. When the communication is disconnected (step SC20), the control unit 37 ends the call process.

According to the configuration of this example, substantially the same effect as that of the above-described fourth embodiment can be obtained.
In addition, for example, when the operator holds the mobile phone 1A at the call position and listens to a message message output from the voice output unit 32, even if there is an incoming call, the voice output unit 32 An alarm announcement is output, and a ringtone is output at a timing at which the operator can estimate that the mobile phone 1A has been sufficiently separated from the ear, so that the operator's ear can be more reliably protected from unexpected loud sound. it can.
