DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the operation of the present invention will be described below.

In the telephone as the portable electronic device of the present invention, one or a plurality of photodiodes are arranged on the outer surface of the housing as light receiving elements for detecting ambient light. When the photodiode detects light when the power of the mobile phone is turned on or when a specific key arranged on the outer surface of the housing is pressed, a test sound is output from the speaker, and the echo sound is collected by the microphone. The sound volume is stored as a reference value.

In the portable telephone, if the photodiode does not detect light when an incoming call is received, a test sound is output from the speaker, the echo sound is collected by a microphone, and the sound volume is compared with a reference value. As a result, if the volume of the reverberation sound is higher than the reference value, the call volume is increased. Thus, even when the mobile phone is housed in a bag or the like, a ringing tone can be heard well from outside the bag or the like.

Further, the photodiode detects light even when the mobile phone is housed in a bag or the like, and if the light is detected when the mobile phone is taken out of the bag or the like, the output of the ringing sound is cut off. Light emitting element (light emitting diode, etc.)
Flashing.

Thus, even when the ringing tone is louder, it is not possible to take it out of a bag or the like, so that it is possible to prevent the ringing tone from disturbing others. By arranging the light receiving surface of the photodiode on the outer surface of the housing, light around the mobile phone can be detected even when the mobile phone is held in a hand or on a desk.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In the figure, a mobile phone according to an embodiment of the present invention includes an antenna 1, a transmission / reception circuit 2, a control circuit 3, a light receiving element 4, a microphone 5, a memory 6, a speaker 7, and an LED (Light Emitting Di).
mode: light emitting diode).

When the transmission / reception circuit 2 detects an incoming call from a signal received via the antenna 1, the incoming call is detected by the control circuit 3
Notify. The light receiving element 4 is composed of one or a plurality of photodiodes, and their light receiving surfaces are arranged on an outer surface of a casing (not shown). The photodiode has a light-receiving surface located at one or more locations on the outer surface of the housing, so that light around the mobile phone can be detected even when the mobile phone is held in a hand or on a desk. .

The microphone 5 collects a user's voice during a normal call. The voice collected by the microphone 5 is transmitted to the destination via the control circuit 3, the transmission / reception circuit 2, and the antenna 1.
The loudspeaker 7 outputs a voice transmitted from a communication destination via the antenna 1, the transmission / reception circuit 2, and the control circuit 3.

A control circuit 3 composed of a microprocessor or the like controls each of the above components. Specifically, the control circuit 3
When the light receiving element 4 detects light when the power is turned on or when a specific key (not shown) arranged on the outer surface of the housing is pressed, a test sound is output from the speaker 7 and the echo sound is generated. The sound is collected by the microphone 5 and the sound volume is controlled to be stored in the memory 6 as a reference value.

Further, when the control circuit 3 is notified of the incoming call from the transmitting / receiving circuit 2, if the light receiving element 4 does not detect the light, the control circuit 3 outputs a test sound from the speaker 7, and the echo sound is collected by the microphone 5. The sound volume is compared with a reference value stored in the memory 6. As a result, if the volume of the reverberation sound is higher than the reference value, the control circuit 3 increases the volume of the ringing tone output from the speaker 7.

On the other hand, the light receiving element 4 detects light even when the mobile phone is housed in a bag or the like. When the light receiving element 4 detects light when the mobile phone is taken out of the bag or the like, the control circuit 3 Turns off the ringing tone output from the speaker 7, and notifies the incoming
Switch to the flashing light.

FIG. 2 is a flow chart showing a ringing tone test process (reference value setting process) according to the present invention. The ringing tone test process is performed in a bright place with light, and the value at that time is stored in an EPROM or the like.

Referring to FIG. 2, the control circuit 3 detects that the light receiving element 4 detects light when the power is turned on or when a specific key arranged on the outer surface of the housing is pressed (step S1 in FIG. 2). The test sound is output from the speaker 7 (see FIG. 2).
Step S2).

When the reverberation sound of the test sound output from the speaker 7 is collected by the microphone 5 (step S3 in FIG. 2), the control circuit 3 stores the reverberation sound collected by the microphone 5 as a reference value in the memory. 6 (step S3 in FIG. 2).

FIG. 3 is a flowchart showing the calling process. In FIG. 3, when the control circuit 3 in which the reference value is set is notified of the incoming call from the transmitting / receiving circuit 2, if the light receiving element 4 does not detect the light (step S11 in FIG. 3), the speaker 7 outputs the test sound. (Step S12 in FIG. 3).

When the echo of the test sound output from the speaker 7 is collected by the microphone 5 (step S13 in FIG. 3), the control circuit 3 compares the echo with the reference value stored in the memory 6 (FIG. 3). 3 steps S14).

As a result, if the volume of the reverberation sound is higher than the reference value, the control circuit 3 determines that the telephone is in a bag or the like and increases the volume of the ringing tone output from the speaker 7 (FIG. 3).
Step S15). On the other hand, if the volume of the reverberation is lower than the reference value, it is determined that the telephone is outside the bag (the pocket of the clothes), and a ringing tone of a normal volume is output from the speaker 7 (step S16 in FIG. 3).

On the other hand, the light receiving element 4 detects light even when the mobile phone is housed in a bag or the like. When the light is detected by the light receiving element 4 when the mobile phone is taken out of the bag or the like (FIG. 3 step). S17), the control circuit 3 cuts off the ringing sound output from the speaker 7, and switches the call notification from the ringing sound by the speaker 7 to the blinking light by the LED 8 (FIG. 3).
Step S18). Thereafter, when the mobile phone is off-hook (step S19 in FIG. 3), or when the power is turned off before the call or the call is disconnected before the call, the control circuit 3 turns off the blinking light by the LED 8 (FIG. 3). Step S
20).

On the other hand, when the light receiving element 4 detects light at the time of incoming call (step S11 in FIG. 4), the control circuit 3 outputs a ringing tone of a normal volume from the speaker 7 and LE
D8 blinks (step S21 in FIG. 3).

When the mobile phone goes off-hook (step S22 in FIG. 3), or when the power is turned off before the call or the call is disconnected before the call, the control circuit 3 controls the speaker 7.
Is turned off, and the LED 8 is turned off (step S23 in FIG. 3).

On the other hand, if no light is detected in step 17, it is considered that the outside is dark or the bag has not been taken out of the bag. When the outside is dark, when the off-hook is detected (S24), the ringing tone is cut off (S25). On the other hand, when it is not taken out of the bag, it is considered that the sound cannot be heard, and the output of a loud sound is repeated.

As described above, when an incoming call is detected by the transmission / reception circuit 2 and no light is detected by the light receiving element 4, a test sound of a predetermined volume is output from the speaker 7, and the test sound is echoed around the own device. When the mobile phone is housed in a bag or the like by controlling the control circuit 3 to increase the ringing volume when the control circuit 3 determines that the volume of the reverberation sound is higher than the reference value by collecting the reverberation sound by the microphone 5. However, the ringing tone can be heard well from outside such as a bag.

Further, when the detection result of the light receiving element 4 changes from non-detection of light to detection of light, the control circuit 3 cuts off the ringing sound from the speaker 7 and notifies the incoming call by the blinking light of the LED 8. When the mobile phone is removed from a bag or the like during a call, the ringing sound from the speaker 7 is interrupted, so that the ringing sound does not bother others.

In the above example, the loud sound outputs a sound of a predetermined volume, but if the loud sound is still not taken out of the bag, the loud sound can be gradually increased.

[0038]

As described above, according to the portable telephone of the present invention, a test sound having a preset volume is output from a speaker at the time of an incoming call, and a reverberation sound that the test sound resonates around its own device is transmitted to a microphone. In the case where the mobile phone is housed in a bag or the like, the sound is collected from the outside of the bag or the like even when the mobile phone is housed in the bag or the like by controlling the ringing volume to be increased when it is determined that the volume of the reverberation sound is higher than a preset reference value. There is an effect that the ringing tone can be heard well.

According to another portable telephone of the present invention,
When the above detection result changes from non-detection of light to detection of light, the output of the ringing tone is cut off and the incoming call is notified by flashing light, so that when the mobile phone is taken out of a bag or the like during a call, the ringing tone is output. Thus, there is an effect that it is possible to prevent annoying surrounding people.
