Reference numeral 1 denotes a synthetic resin housing having a U-shaped cross section. A flexible diaphragm 32 is stretched inside the housing 31 so as to close the opening of the diaphragm 32. A piezoelectric element 33 that causes distortion in the crystal due to these vibrations is attached to one side. Note that this piezoelectric element 33 is polarized by the generation of the strain, and a polarization voltage can be taken out from the diaphragm 32 and the piezoelectric element 33 via the lead wire 34.

力することができる。 In such a bone conduction microphone 26, the sound generated by a person's mouth is transmitted to the temporal bone structure as vibrations, so these vibrations are transmitted to the diaphragm 32 via the contact plate 35 that is in contact with the temporal region. is transmitted with high sensitivity. Therefore, the crystal of the piezoelectric element 33 is distorted in response to the vibration of the diaphragm 32, and a polarization voltage corresponding to this distortion is outputted via the lead wire 34. Further, this output voltage is amplified and input directly or wirelessly to another handset, so that the headphone can output audio free of external noise.

の危険が回避されるのである。 Thus, in the above-described handset having the bone conduction microphone 26 for speaking and the headphone 24 for receiving at both ends of the headband 21, when having a conversation with another person, one ear is always used without blocking both ears. Since the ears are open so that external sounds can be heard, it is possible to distinguish between the operating sounds of civil engineering machinery, etc., and the dangers at construction sites, etc. that would otherwise occur when both ears are covered can be avoided. .

実用上の利点が得られるものである。 As explained above, according to the present invention, a headphone is attached to one end of the headband, and
By attaching a bone conduction microphone to the other end that can touch the temporal region of the head, it is possible to safely send and receive conversations without blocking both ears.
It is possible to clearly distinguish between transmitted and received voices.
Additionally, external voices and noise can be heard through the other unobstructed ear, providing the practical advantage of allowing normal conversation with others who do not have similar devices. .
