Alternatively, when the mobile phone unit 12 receives a call while the radio receiving unit 11 is selected, the user receives a ring tone (not shown, for example, a speaker in the multi-function portable terminal device 1). The microphone 24 or its support 23 is rotated from the position of the rotation angle B or the rotation angle C to the position of the rotation angle A. Since the operation at this time is a snap action operation, the microphone 24
Can be correctly positioned at the rotation angle A. Then, A1 is selected by the rotary switch 22b, and the selection signal is transmitted to the selector 14, and the output of the mobile phone unit 12 is immediately output to the speaker 20. At this time, since the microphone 24 is simultaneously moved to the position of the rotation angle A, that is, the mouth of the user, the user can immediately use the mobile phone in that state. Further, when the MP3 player 10 is selected and the radio receiver 11 is to be selected, the user moves the microphone 24 or its support 23 from the position of the rotation angle B to the position of the rotation angle C. Then, the selector 14 selects the radio receiving unit 11, and radio sound is output from the speaker 20. At this time, since the microphone support 23 has a position approximately perpendicular to the headset main body 21 as shown in FIG. 1, the microphone support 23 is used as an antenna having the maximum reception sensitivity.

In the above-described embodiment, the mode in which the microphone support 23 is used as an antenna is only for radio reception. However, even when the mobile phone unit 12 is selected, the microphone support 23 is not used. It can be used as an antenna. Usually, the reception frequency band in this case is several hundred MHz to several GHz, so that signal processing in the high-frequency signal unit 25 may be complicated. Therefore, in such a case, the high-frequency signal unit 25 may convert the digital signal into a digital signal and output the digital signal to the radio receiving unit 11. Also,
All signals flowing through line 3 are converted into digital signals, and A /
The D set and the D / A set are respectively connected to the headset 2
And it is also possible to provide in the multifunctional portable terminal device 1.

Further, in the above-described embodiment, the headset body 21 is positioned at the verbal portion of the user as shown in FIG. 1, but as shown in FIG. 3, it is positioned from the top of the head to both ears. You may do so. In this case, it is desirable that the radio receiving unit 11 be selected at the position of the rotation angle B.

[0031]

According to the present invention, the mobile phone mode can be switched to the mobile phone mode with one touch immediately after receiving a call on the mobile phone, so that the ringing tone does not bother the surroundings, and the operation at that time can be performed. Operability is very good because only the position of the microphone is changed.

Since the microphone support is also used as an antenna, there is an advantage that it is not necessary to separately provide an antenna for receiving radio.
