[0014]

In the wireless portable telephone of the present invention (1) of FIG. 1 (A), the transmission sound signal of the microphone 5 is recorded according to the operation of the first key (for example, the "memo" key) while the telephone is not in a call. In addition to recording / playback to the playback unit, the playback unit 6 mixes the playback sound signal of the recording / playback unit and the transmission sound signal of the microphone 5 according to the operation of the first key during a telephone call, and sends the mixed sound signal from the wireless unit 30.

Therefore, a message of the self or a third party, a cry of a bird or an insect, a crowded sound of the city, a sound of a sea noise, etc. are recorded from the microphone 5 in advance during a non-call, and this is recorded independently during a call. Or, it is possible to make the called party listen to the recorded content by reproducing it as a background sound, which is a convenience different from the conventional mobile phone. Preferably, according to the operation of the second key (for example, the “mute” key), the transmission sound signal of the microphone 5 during the call of the telephone is muted / non-muted. If the transmission sound signal of the microphone 5 can be silenced, the requirements can be clearly transmitted even in noise.

Further, preferably, the transmission sound signal of the microphone 5 is recorded in the recording / reproducing section in accordance with the operation of the first key (for example, the "memo" key) during the non-call of the telephone.
A first operation of mixing the reproduction sound signal of the recording / reproducing unit and the transmission sound signal of the microphone 5 according to the operation of the first key (“memo” key) during a telephone call and transmitting from the wireless unit 30 According to the operation of the mode and the operation of the first key (“memo” key) during a telephone call, the transmission sound signal of the microphone 5 and the reception sound signal of the wireless unit 30 are mixed and recorded in the recording / reproducing unit. , A second that outputs a reproduction sound signal of the recording / reproducing unit to the speaker 4 according to the operation of the first key (“memo” key) during non-call of the telephone

Returning to FIG. 2, when the power of the telephone of this embodiment is turned on, power is first supplied to the radio unit 30, the control unit 3, the display unit 6, and the keyboard unit 7. In this state, when the user makes a call to the base station via the control channel CCH and the call connects to the called party, the call is made. Alternatively, when the "start" key is pressed to accept an incoming call from the other party, the call is started. During a call,
Further, the power switch 42 is turned on, and power is also supplied to the audio system circuit unit 10. Also, the switch 24 is turned on every time during a call.
The mute flag, which will be described later, of the control unit 3 is reset accordingly.

Basically, the sound transmitted by the microphone 5 during a call is switched by the switch 24, the summing amplifier 14, and the modulator 3.

Since it is FF, power is not supplied to the audio circuit unit 10.

FIG. 3 is a flowchart of the recording / playback control of the first embodiment. In the first embodiment, the keyboard portion of FIG. 11A provided with a single "memo" key is used, and the transmission sound (or background sound) of the microphone is pushed by pressing the "memo" key during a non-call in advance. Etc.) is recorded in the recording / playback unit, and then by pressing the “memo” key during a call, the playback sound of the recording / playback unit and the microphone transmission sound can be mixed and transmitted from the wireless unit. . In addition,
In order to realize this function, it suffices if there is a summing amplifier 14,
Note that switches 22 and 24 can be omitted (shorted).

If the "memo" key is input, this process is input. In step S21, it is determined whether or not a call is in progress. If no call is in progress, the following recording process is performed. That is, in step S22, first, the power switches 42, 41 are turned on to supply power to the audio system circuit unit 10. Switch 23 to OF
Change to F. Furthermore, the recording / playback control unit 1 is set to the recording mode (RW
= 1), the timer is started (ST = 1), and the timer is activated to start recording time measurement. In this state, the transmission sound signal of the microphone 5 is input to the summing amplifier 12, and its amplified output is input to the recording / playback control unit 1.

Subsequently, in step S23, it is determined whether or not the "memo" key is re-input, and if it is not the "memo" key is re-input, it is further determined in step S24 whether or not the timer is time-up 1. If it is not Tiam Up 1, the process returns to step S23 to continue recording. If the “memo” key is pressed again during recording, this means that the user stops recording. When the recording is performed up to the capacity limit of the memory 2, the time is up 1. In these cases, the process proceeds to step S25, and the recording is stopped (ST =
0) Further, the timer is stopped and the recording time is recorded in the memory of the control unit 3. Furthermore, it is preferable to turn off the power switch 41 to exit the process.

ON / OF of the power switch 41 as described above
The F control enables further power saving without erasing the recorded data in the memory 2. Power switch 41 ON / OFF
The control may be applied to all analog circuits of the audio system circuit unit 10 except the memory 2. Alternatively, instead of providing the power switch 41, the power supply control of the entire audio system circuit unit 10 may be performed only by the power switch 42 by using the memory 2 as a backup power supply system. In addition, the recording / playback control unit 1 is a CMO.
If it is composed of S etc., AND gate circuit 2
Even if the supply / stop control CE of the clock signal CK is performed by 6, the power saving effect can be obtained.

Returning to the flow, if it is determined in step S21 that a call is in progress, the following reproduction process is performed. That is, in step S31, it is determined whether or not there is recorded data, and if there is no recorded data, in step S32, "no recorded data"
Is displayed on the display unit 6. The presence / absence of recorded data can be determined by, for example, whether or not the recording time recorded in the control unit 3 = 0. Alternatively, a flag indicating presence / absence of recorded data may be provided and ON / OFF controlled.

If it is determined in step S31 that there is recorded data, the switch 22 is turned on in step S33. The switch 21 may be further turned on when the user hears the reproduced sound. Next, the recording / playback control unit 1 is started (ST = 1) in the playback mode (RW = 0),
Start the timer for measuring the playback time. In this state, the reproduction sound signal of the recording / reproduction control unit 1 is mixed by the summing amplifier 14, and the reproduction sound signal alone or together with the transmission sound signal of the microphone 5 is transmitted to the antenna 3 via the radio unit 30.
5 is transmitted.

Subsequently, in step S34, it is determined whether or not the "memo" key is re-input, and if it is not re-input of the "memo" key, it is further determined in step S35 whether or not the timer is time-up 2. If it is not Tiam Up 2, the process returns to step S34 to continue the reproduction. Eventually, if the "memo" key is input again during playback, this means that playback is restarted from the beginning, and control is performed in step S
Return to 33. When the reproduction measurement time becomes equal to the recording time recorded in the control unit 3, the time is up 2. In this case, the process proceeds to step S36, and the reproduction is first stopped (ST
= 0). Further, the timer is stopped and the switch 22 (and the switch 21 if necessary) is turned off. Further, the power switch 41 is turned off, and the process ends.

FIG. 4 is a flowchart of the mute control of the embodiment. According to this embodiment, the user can turn on / off the transmission sound of the microphone 5 by pressing the "mute" key at any time. In FIG. 2, a switch 24 is provided to realize the mute control function. If the "mute" key is input, this processing is input. In step S26, it is determined whether or not the mute is being performed. This determination is made by checking the mute flag of the control unit 3. If the mute is being performed (mute flag = 1), the switch 24 is turned on in step S27 to cancel the mute state, and the mute flag is reset. If not muted (mute flag = 0), the switch 24 is turned off in step S28 to set the mute state, and the mute flag is set.

FIG. 5 is a flowchart of the recording / playback control of the second embodiment. In the second embodiment, the keyboard portion of FIG. 11A is used in the same manner as above, and the transmission sound is recorded during the non-call by the mode setting or the key operation, and this is recorded during the call. First read to the wireless unit 30
It is possible to switch between the above operation mode and the second operation mode in which a call sound during a call is recorded and read out to the speaker 4 during a non-call as in the conventional case. In FIG. 2, summing amplifiers 11 and 12 and switches 21 and 23 are provided to realize this function.

If the "memo" key is input, this process is input. In step S20, it is determined whether or not the mode is set. The user can set the mode by a mode changeover switch (not shown) or a function setting operation of the keyboard unit 7. If no mode is set, step S in FIG.
The process proceeds to step 21 and operates in the first operation mode. If the mode is set, the process proceeds to step S41, and the second operation mode similar to the conventional one is used.

That is, in step S41, it is determined whether or not a call is in progress, and if a call is in progress, the recording process after step S42 is performed. If no call is being made, the reproduction process from step S51 is performed. Figure 1 shows these recording / playback processes.
The description is omitted because it is almost the same as 3. The difference is that ON / OFF control of the power switch 41 and the analog switch 23 is added.

FIGS. 6 and 7 are flow charts (1) and (2) of the recording / playback control of the third embodiment. In the third embodiment, the keyboard portion of FIG. 11B, which is provided with a "record" key and a "playback" key, is used,
The recording / reproducing operation of FIGS. 3 and 5 can be arbitrarily performed regardless of the non-call. In FIG. 6, if the "record" key is input, this processing is input. In step S61, it is determined whether or not a call is in progress. When not in a call, the recording process after step S22 similar to FIG. 3 is performed, and when in a call, the recording process after step S42 similar to FIG. 5 is performed. .

In FIG. 7, if the "play" key is input, this process is input. In step S62, it is determined whether or not there is recorded data, and if there is no recorded data, a message "no recorded data" is displayed on the display unit 6 in step S64.
Exit the process. If there is recorded data, step S
In 63, it is further determined whether or not the call is in progress. If the call is not in progress, the reproduction process after step S53 similar to FIG. 5 is performed, and if the call is in progress, the reproduction process after step S33 similar to FIG. 3 is performed. .

FIG. 8 is a flow chart of recording / playback control of the fourth embodiment. In the fourth embodiment, by using the "F" key, a plurality of transmitted voice messages can be individually recorded / played back. Here, a case where the recording / playback control of a plurality of messages is applied to the first embodiment of FIG. 3 will be described. If the "F8X" key is input during a non-call, it is input to the recording process after step S71. Briefly explaining the contents of F8X, "F80" ends recording and "F81"
-"F84" represent recording of messages (1)-(4), respectively. In step S71, the storage address DSL of the message is generated according to the contents of "F81" to "F84". The recording process after step S22 is substantially the same as that in FIG. The different point is that the recording is stopped when the "F80" key is input in step S23. Furthermore,
Recording management of the time-up 1 and the recording time is individually performed for each of the messages (1) to (4).

If the "F9X" key is pressed during a call, the key is input to the reproduction process after step S72. F9X
To briefly explain the contents of the above, "F91" to "F94" represent reproduction instructions of the recorded messages (1) to (4), respectively.
In step S72, the read address DSL of the message is generated according to the contents of "F91" to "F94". The reproduction process after step S31 is substantially the same as that in FIG. The difference is that in step S34, "F91"-
If there is any key input of "F94", step S7
Returning to step 2, the reproduction of a new designated message is restarted. Therefore, by selectively using one or two or more recorded messages during a call, it is possible to have a conversation with the called party even if the user does not speak. Also here, the time monitoring of the time-up 2 is individually performed for each of the recording messages (1) to (4).

In this case, it is preferable that the time monitoring of the time-up 2 is the recording time of step S25 + α. In this way, the user can give an instruction to reproduce the next message with a sufficient margin after reproducing one message. Further, it is apparent that the recording / playback control of the plurality of messages can be applied to the second embodiment of FIG. 5 and the third embodiment of FIGS. 6 and 7, respectively.

FIG. 9 is a block diagram of a wireless mobile phone according to another embodiment. Here, instead of the recording / playback unit composed of the recording / playback control unit 1 and the memory 2 of FIG.
It has. Along with this, the analog circuit for recording in FIG. 2 is omitted. The voice synthesizer 9 uses the address signal D
The voice message of the address designated by SL can be synthesized and output to the output terminal AO.

FIG. 10 is a flow chart of message composition control of another embodiment. If the "F7X" key is pressed during a call, the key is input to the combining process after step S81.
Briefly explaining the contents of F7X, "F71" to "F7"
“4” represents an instruction to generate the composite messages (1) to (4), respectively. In step S81, the composite address DSL of the message is generated according to the contents of "F71" to "F74". In step S82, the message is displayed on the display unit 6 for confirmation. At the same time, a timer for measuring the display time is started. The control unit 3 has a known display message corresponding to each composite address DSL in its internal memory. In step S83, the process waits for time-up 3 (for example, about 1 second).

Eventually, when the time is up, the process proceeds to step S33 and subsequent synthesizing processes. The composition process after step S33 is substantially the same as the reproduction process after step S33 in FIG. The difference is that the reproduction operation is changed to the composite operation. Therefore, by selectively using one or two or more synthetic messages during a call, it is possible to have a conversation with the called party even if the user does not speak. Also here, the time monitoring of the time-up 2 is individually performed for each of the combined messages (1) to (4).

By the way, if the user notices an error after displaying the message in step S82, he or she may immediately re-enter another "F7X" key. The flow is
When the re-input of the "F7X" key is detected in the first step S34, the process returns to step S81 before the synthetic voice is generated. Therefore, it is possible to prevent the transmission of the error message.

The processes of steps S82 and S83 may be omitted. Further, the synthesis control of this embodiment can also be applied when the "F7X" key is input during a non-call.
In this case, the switch 42 is turned off in step S33.
