[0013]   In FIG. 5, the mobile phone 1 with headphone stereo is a conventional headphone Like the Tereo, it is formed in a box shape and has a numeric keypad (numerals 0 to 9) on the body panel surface 8. Operation buttons 24 such as keys), a display unit 25, a buzzer 26, an earphone jack 9 and.

[0014]   Next, the operation of this embodiment will be described with reference to the flowchart of FIG. When a call is first received (received) in S1, the process proceeds to S2 and the changeover switch 6a to 6d are connected to the headphone stereo unit 2 (headphone stereo Mode). When in headphone stereo mode, proceed to S3 The ringing signal is converted into an electronic sound (ringing sound) by the microcomputer 23, and the ringing sound priority circuit 27 is provided. And is reproduced by the earphones 7a and 7b via the preamplifiers 12a and 12b. It That is, even if the user listens to music in the headphone stereo mode, the incoming call If so, the ringing tone is reproduced by the earphones 7a, 7b in preference to music or the like. Next, the user who knows that the call is received proceeds to S5, and the changeover switch 6a to 6d are connected to the telephone unit 3 (telephone mode) and the process proceeds to S6. In addition, the ring tone Yu The destination circuit 27 may be configured so that a ringing tone, music and the like are mixed and reproduced. on the other hand , S2, in the telephone mode, the process proceeds to S4, and the buzzer 2 provided on the body panel surface 8 is After ringing 6, the process proceeds to S6.

[0015]   In S6, the earphone 7a operates as a transmitter in the present embodiment, and the earphone 7b operates as a receiver. Of course, this may be reversed. Next, in S7, send and receive Is completed, the process proceeds to S8, and the changeover switches 6a to 6d are set to the headphone stereo. When returning to the mode, music or the like is played again.

[0016]   Further, a so-called answering machine function generally used may be added to the telephone section 3.   In this case, the headphone stereo section 2 is provided with a recording function for recording absences. It is necessary to keep it. However, if you just need to send a message when you are out, It is not necessary to provide a sound function.

[0017]   First, in the telephone mode, a magnetic tape dedicated to absence recording instead of a magnetic tape for music, etc. Set. Next, when an incoming call arrives, the buzzer 26 sounds, and the user Use 7a and 7b to send and receive. On the other hand, the main body panel surface 8 or remote control operation The section 6 has a switching switch (not shown) for selecting a transmission / reception mode or an answering machine mode in advance. There is a switch. That is, in the answering machine mode, the input side of the modulator 21a Connect to the output side of the amplifier 4a or 4b of the headphone stereo section 2, An output side of the demodulation section 21b and a recording input end (not shown) of the headphone stereo section 2 Connect with a child. By doing this, the magnetic tape is played in the answering machine mode. The sound is modulated by the modulator 21a and transmitted via the handset 22 and the antenna 5 ( While the signal is transmitted, the signal received (received) is transmitted via the demodulator 21b to the magnetic tape. Will be recorded in the loop.

[0018]   As described above, according to the present invention, the headphone stereo and the mobile phone are integrated. Since it is a body, it is possible to use the microcomputer, operation buttons, display, etc. in common. Therefore, it is possible to reduce the size and cost. Also, for the user, two units have been used. The required device can be completed with one unit, making it easy to carry around.

[0019]

[Effect of device]

  The headphone stereo and the mobile phone can be used together. Also, the ratio Since this is a combination that makes it easy to use common comparative circuits, it is possible to reduce the size and cost.
