At the time of reception, digital modulation / demodulation section 4 performs demodulation processing on the π / 4 shifted QPSK signal input from radio section 3 and outputs received data. On the other hand, at the time of transmission, modulation processing is performed on the input transmission data, and a π / 4 shifted QPSK signal is output.

At the time of reception, the TDMA processing unit 5 receives data input from the digital modulation / demodulation unit 4, that is,
Data of a preset downlink slot is selected from time-division multiplexed data of a plurality of slots, and separated into control data and compressed audio data.

At the time of reception, the audio codec 6
The audio compression data input from the MA processing unit 5 is subjected to decoding processing (including error correction processing) and outputs a received audio signal. On the other hand, at the time of transmission, a compression encoding process (including a process of adding an error correction code) is performed on an input transmission audio signal to output compressed audio data.

The low-frequency amplifier 7 amplifies the received audio signal input from the audio codec 6, and the loudspeaker 8 outputs a sound based on the output audio signal of the low-frequency amplifier 7. The microphone 9 as a transmitter receives an audio signal, and the low-frequency amplifier 10 amplifies the audio signal input from the microphone 9 and outputs the amplified audio signal to the audio codec unit 6.

In addition to the state of the system, the display unit 15 displays the telephone directory data selected in the search of the telephone directory data, the telephone number input by the ten keys, and the like. It is also possible to notify the incoming call by blinking the screen or performing a predetermined display when there is an incoming call. The non-volatile memory 12, the ringer output unit 13, the operation unit 14, and the display unit 15 are connected to the control unit 11, respectively.

Next, a portion relating to the music playback function of the mobile phone according to the present embodiment will be described. The semiconductor memory 16 is a rewritable and removable semiconductor storage medium. For example, a flash card corresponds to this.
MP3 (MPEG Audio) is stored in the semiconductor memory 16.
Music data compressed using a compression technique such as Layer 3) is stored. When data is compressed using the compression technique of MP3, the data amount can be reduced to about one tenth of that of a normal PCM signal although the sound quality is slightly deteriorated. It is possible to secure a sufficient music playback time even if a small-capacity medium is used.

The MP3 decoder 17 has a DSP (Digital)
The semiconductor memory 16 is provided with a semiconductor circuit such as a TAL Signal Processor, and reads out music data stored in the semiconductor memory 16, expands the music data into a PCM signal, and outputs the PCM signal.

And a low-pass filter, which performs digital / analog conversion on the PCM signal input from the MP3 decoder 17 and demodulates it into an analog signal. In addition, the demodulated analog signal is amplified and output to an amplitude value that can be reproduced at a sufficient volume.

The headphone jack 19 is an external output terminal. That is, it is a signal terminal for outputting a signal to an external playback device such as a headphone (not shown) instead of the speaker 8. Normally, when a headphone-side terminal is connected to the headphone jack 19, the driving of the speaker 8 is stopped. As shown in FIG. 1, both the output signal of the low-frequency amplifier 7 and the output signal of the headphone amplifier 18 are input to the headphone jack 19, and the user can listen to these with headphones.
The above-described semiconductor memory 16, MP3 decoder 17,
The headphone amplifier and the headphone jack 19 are controlled by the control unit 11.

Next, the operation of the cellular phone according to the present embodiment configured as described above will be described. FIG.
4 is a flowchart showing a first operation of the mobile phone according to the embodiment. First, a user connects a connection terminal of a headphone (not shown) to the headphone jack 19.
Next, the semiconductor memory 16 such as a flash card is mounted on the apparatus main body, and an operation for instructing reproduction is performed from the operation unit 14. The control unit 11 outputs a control signal to each component, and controls the mobile phone to play music. That is, the MP3 decoder 17 is connected to the semiconductor memory 1
6 is read out, expanded to a PCM signal and output. The headphone amplifier 18 is an MP3
The PCM signal input from the decoder 17 is
Analog conversion and demodulation into analog signals. In addition, the demodulated analog signal is amplified and output to an amplitude value that can be reproduced at a sufficient volume. The output signal of the headphone amplifier 18 is output as sound to headphones (not shown) via a headphone jack 19. Thus, the music data is reproduced (step S1).

During the reproduction of such music data, the portion related to the communication function is in a standby state, and constantly monitors whether there is an incoming call (step S2).
If there is no incoming call, the determination in step S2 is repeated,
If there is an incoming call, the music reproduction is stopped (step S3). When the reproduction of the music is stopped, the position of the entire music data at the time of the stop is stored (step S4).

As described above, when an incoming call is detected during the reproduction of the music data, the reproduction of the music data is stopped.
Switching from the music playback function to the communication function can be performed automatically. This eliminates the need for the user to perform a troublesome operation when an incoming call is received during music playback. Further, since the position at which the reproduction of the music data is stopped is stored, it is easy to grasp the stop position when the reproduction is restarted.

When the stop position is stored in step S4, it is notified that there is an incoming call (step S5).
As the notification method in step 5, it is possible to play an electronic alarm sound, a so-called “ringtone” music, in addition to a telephone bell. Further, it is also possible to notify by vibration in the manner mode, blinking of the screen, or a predetermined display.

Next, it is determined whether or not the user has answered (step S6). If the user has not answered, it is determined whether or not the incoming call is terminated (step S7). If the incoming call has not ended, the process proceeds to step S6, and if the incoming call has ended, the process proceeds to step S10.

On the other hand, if the user responds to the incoming call in step S6, the telephone is ready to talk (step S8). Next, it is determined whether or not the call has ended (step S9). If the call has not ended, the determination in step S9 is repeated. On the other hand, when the call is terminated, the reproduction of the music data is restarted from the stop position stored in step S4 (step S10).

As described above, when the incoming call ends or the response to the incoming call by the user ends, the reproduction of the music data is restarted from the position at the time of the stop, so that the switching from the communication function to the music reproducing function is automatically performed. It is possible to perform it. Thus, when the communication is completed, the music that was being listened to before the incoming call is automatically reproduced, so that the user can continue to listen to the music without performing a troublesome operation.

As a variation of the operation in step S10, when the incoming call or the response to the incoming call is completed, it is also possible to adopt a configuration in which the reproduction of the music data is resumed from a position which is a predetermined unit earlier than the position at the time of the stop. It is. Here, the predetermined unit includes time, a scale of a counter, and the like. That is, when taking time as a unit, reproduction is performed from a position several seconds or several tens seconds back from the position at the time of stop. Also, if a counter is provided, the count will increase with playback,
If the scale of the counter is taken as a unit, the reproduction is started from a position where the scale is returned by several scales.

As described above, when the incoming call ends or the response to the incoming call by the user ends, the reproduction of the music data is restarted from a position which is a predetermined unit earlier than the stop position. As a result, the user can listen to the music again from a position slightly returned from the position at the time of stop.

Further, as another variation in step S10, when the incoming call or the response to the incoming call ends, it is possible to adopt a configuration in which the reproduction of the music data is restarted from the initial position of the music data.

As described above, when the incoming call ends or the response to the incoming call by the user ends, the reproduction of the music data is restarted from the initial position of the music data. This allows the user to listen to the music again from the beginning of the song.

Next, it is determined whether or not the reproduction of the music data has been completed (step S11). If the reproduction of the music data has not been completed, the process proceeds to step S2, and if the reproduction of the music data has been completed, the process ends. .

Next, a second operation of the mobile phone according to the above embodiment will be described with reference to a flowchart shown in FIG. Until the music data is reproduced, the operation is the same as the first operation shown in FIG. 2 (step T1). During the reproduction of the music data, the portion related to the communication function is in a standby state, and constantly monitors whether there is an incoming call (step T2). If there is no incoming call, the determination in step T2 is repeated, and if there is an incoming call, the position of the entire music data at the time of incoming call is stored (step T3). Next, as in step S5 in the first operation, an incoming call to the user is notified (step T4). Therefore, while the call is received and the notification is being performed, the reproduction of the music is continued.

Next, it is determined whether or not the user has answered (step T5). If the user has not answered, it is determined whether or not the incoming call has been completed (step T6). If the incoming call has not ended, the process proceeds to step T5, and if the incoming call has ended, the process proceeds to step T10.

On the other hand, if the user responds to the incoming call in step T5, the reproduction of the music data is stopped (step T7), and the call becomes possible (step T5).
8).

As described above, when an incoming call is received during the reproduction of music data and a response is detected, the reproduction of the music data is stopped, so that the switching from the music reproduction function to the communication function can be automatically performed. It becomes possible. For this reason, the user
Even if there is an incoming call during the reproduction of music, the music is automatically stopped by responding to the incoming call, so that there is no need to perform a troublesome operation.
