And a wireless telephone communication unit for making a telephone call with another telephone device, and having a function of reproducing audio information recorded on a recording medium and a telephone function by one device. it can. Further, a human body-mounted microphone section and an earphone section are connected to the audio signal input / output section. The detection signal of this microphone section is transmitted to the telephone communication section, and the audio output signal of the reproduction section and the telephone The voice output signal of the call section can be transmitted to the voice signal input / output section.

[0005] Therefore, when the user of the portable audio information handling device wears the microphone unit and the earphone unit on a part of the user's body, the user of another telephone device can use the microphone unit and the earphone unit. And the user can listen to the audio information recorded on the recording medium with the earphone unit. In other words, in order to avoid the cumbersome operation of holding the main body of the device in hand and making a call while pressing the speaker portion against the ear, a human body-mounted microphone unit and an earphone unit are used for the telephone call unit. It is convenient to be able to use the earphone part in order to avoid giving discomfort to others. With the wearable microphone unit and the earphone unit attached, both functions of the telephone communication unit and the playback unit can be used. This simplifies the handling of audio information, and
The structure of the device can be simplified.

In addition, with the above configuration, the microphone unit detects the bone conduction sound to the human ear by the bone conduction microphone, and the detection signal is transmitted to the telephone communication unit. . Therefore, if a general microphone such as a condenser microphone is used for the microphone unit, it is necessary to arrange the microphone unit near the mouth of the user, and the body-mounted microphone unit and the earphone unit are generally large. When using a bone conduction microphone,
The restriction on the arrangement as described above is relaxed, and the microphone unit and the earphone unit to be worn on the human body can be reduced in size. In addition, by detecting the bone-conducted voice, even in the case of talking in a noisy environment, it is possible to make a good communication without being affected by the surrounding noise.

[0007] With the above configuration, the microphone unit includes a bone conduction microphone and detects bone conduction sound to the ear, so that the earphone unit is also attached to the ear. Can be integrally formed, so that the human body-mounted microphone unit and the earphone unit can be further reduced in size.

[0010] With the above configuration, the transmission control unit, when the audio output signal is output from the telephone communication unit, gives priority to the audio output signal output from the reproduction unit. The voice signal is transmitted to the audio signal input / output unit, and the earphone unit can preferentially listen to the voice from the telephone communication unit. Therefore, when a user of the portable audio information handling apparatus receives a call from the other party while listening to the audio information reproduced by the reproduction section, the other party receives a call from the other party by the audio information from the earphone section. It is possible to know what has been done and further simplify handling.

Further, with the configuration according to the fifth aspect, the transmission control section preferentially transmits the audio output signal from the telephone communication section to the audio signal input / output section. In a playback state in which the voice signal is transmitted to the audio signal input / output unit, the telephone call unit transmits the audio output signal of the telephone call unit to the audio signal input / output unit as the telephone call unit receives the transmission signal from the other party of the call. It is switched by the switching means so as to be in the state. As a method of transmitting the audio output signal from the telephone communication unit to the audio signal input / output unit preferentially, for example,
A method of lowering the signal level of the audio output signal of the reproducing unit is also conceivable. However, by switching from the reproducing state to the talking state by the switching unit, it becomes possible to accurately hear the audio information from the telephone talking unit. Since the simple switching operation is used, the device configuration can be simplified.

[0010] With the above configuration, the signal levels of the audio output signal of the reproduction section and the audio output signal of the telephone communication section are adjusted by the level adjusting means and then supplied to the audio signal input / output section. Is transmitted. In other words, it is generally necessary to adjust the signal level of both the audio output signal of the reproducing unit and the audio output signal of the telephone communication unit by providing an amplifier or the like. Utilizing the fact that the audio output signal of both the telephone communication unit and the reproduction unit can be level-adjusted by the level adjusting unit by utilizing the transmission of the audio output signal of Accordingly, the configuration can be further simplified.
