According to the above configuration, when the voice memory is activated during a call, the contents of the call are stored and held in the voice memory, so there is no need to take notes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view showing the external configuration of a mobile phone according to the present invention, and FIG. 2 is a block diagram showing its circuit configuration.

As shown in the figure, this mobile phone 1 includes an upper speaker section 2 that includes a built-in audio speaker 20, and an intermediate operation section 3 that includes a numeric keypad 31 and a recording selection key 32 on the front surface, and a recording execution key 33 on the left side. and a lower microphone section 4 containing a built-in audio microphone 40.

The recording selection key 32 includes an own recording selection key 32a that is turned on when recording the voice of the operator holding the mobile phone 1, and a remote recording selection key 32a that is turned on when recording the voice from the other party. It has a recording selection key 32b.

In addition, a transmitting/receiving antenna 5 for communicating wirelessly with a partner is provided on the upper side of the speaker section 2 near the left end. The audio speaker 20, the audio microphone 40, and the circuit elements shown in FIG. 2 are provided at predetermined positions inside the mobile phone 1.

Hereinafter, the circuit configuration of this mobile phone 1 will be explained along with its operation with reference to FIG. First, a case will be described in which the mobile phone 1 is on the receiving side. When analog voice information arrives from the other party via the nearest NTT relay station, the antenna 5 detects this and outputs it to the high frequency section 11. Then, the high frequency section 11 demodulates the audio information and provides it to the control section 10.

The control unit 10 serves as a control center that controls the entire transmission and reception operation of the mobile phone 1, and transmits analog audio information demodulated by the high frequency unit 11 to the audio codec 1.
Output to 2. The audio codec 12 converts analog audio information into digital code data and outputs it to the audio memory 13 based on a drive command signal from the control unit 0, while outputting the analog audio information to the audio speaker 20. . As a result, the code data is changed to voice memo IJ1.
3, and audio information from the other party is uttered via the audio speaker 20. Note that the audio speaker 20 is driven by a drive command signal from the control unit IO.

The voice codec 12 is driven by a drive command signal from the control section 10 that receives a key command from the operation section 3. That is, when the recording selection key 32 is turned on by the operator number and the recording execution key 33 is turned on, the control unit 1 is turned on while the recording execution key 33 is turned on.
A drive command signal is given to the audio codec 12 from 0,
The digitally converted code data is stored in the audio memory 13.
It is configured to be recorded.

More specifically, when the operator turns on the destination recording selection key 32b and the recording execution key 33, the code data that is digitally converted while the recording execution key 33 is turned on is stored in the audio memory 13. be recorded. As the code data to be recorded in the voice memory 13, important data is selected depending on the storage capacity of the voice memory 13, such as the telephone number of the other party.

Then, in response to the voice information from the other party uttered from the audio speaker 20, the operator inputs a response message to the other party into the voice microphone 40. This response message is transmitted to the other party as follows. will be sent to. That is, the analog response message input to the audio microphone 40 is output to the high frequency section 11 via the audio codec I2 and the control section IO, and is modulated by the high frequency section 11. The modulated response message is sent via the antenna 5 to the nearest relay station of NTT, and then sent to the other party via the telephone line.

The reason for outputting the response message to the high frequency section 11 via the voice codec 12 is that the response message as well as the code data from the other party, that is, the important contents of the call, are stored in the voice memory 13. This is because there are times when you want to record.

The recording operation of the response message into the voice memory 13 is performed in response to a drive command signal from the control section 10. That is, when the operator turns on the self-recording selection key 32a and the recording execution key 33, the voice codec 12 converts the response message into digital code data while the recording execution key 33 is turned on. The code data is recorded in the audio memory 13.

Therefore, depending on the content of the call, the operator can press the other party's recording selection key 32b, the recording execution key 33, or the own recording selection key 3.
2a and the recording execution key 33 are turned on as appropriate, the important contents of the call are recorded in the audio memory 13, so with this mobile phone 1, there is no need to take cumbersome notes as with conventional mobile phones. do not have.

Next, a case where this mobile phone 1 becomes the transmitting side will be explained. When the operator turns on the numeric keypad 31 and selects the telephone number of the other party, the control unit 10 receives this and inputs the telephone number of the other party to the telephone line via the high frequency unit 11, the antenna 5, and the NTT relay station. emit a selection signal,
Thereafter, a response message input into the voice microphone 40 is sent to the other party according to the above procedure.

In the above embodiment, the present invention is applied to an analog mobile phone, but the present invention can be similarly applied to a digital mobile phone. When applied to such a digital mobile phone, there is no need to provide a separate 4-way audio codec, and circuit elements can be shared, which is convenient for simplifying the device configuration.

According to the present invention as described above, the contents of the call are stored in the voice memory, so there is no need to take notes. Therefore,
It has the advantage of being able to reliably retain the contents of a call even while on the move, which greatly improves usability.
