Abstract
A radio transmitter and receiver device in which a head band has a transmitting microphone at one end and a receiving speaker at the other end. This microphone comprises a bone transmission type microphone for detecting aural oscillation of an external auditory canal transmitted through a bone tissue of a head portion from a mouth, said microphone being brought into contact with a side head portion at the rear of an ear. Thus, one ear is blocked by the speaker but the other ear is open, and therefore, a user can catch noises thereabout. A transmitting and receiving antenna has matching means and is mounted on the side of the speaker.

A headset having only one earphone speaker for use with a wireless transmitting and receiving device and capable of being worn on the head of a user without blocking both of the user's ears, the headset comprising:
- a head band dimensioned and configured to be worn on the head of a user of the headset;
- speaker means consisting of only one earphone speaker attached to the head band at a position in which the speaker blocks one of the user's ears during use of the headset;
- and a bone transmission type microphone attached to the head band at a position in which the microphone contacts a side portion of the user's head at the rear of the other of the user's ears without blocking the same to enable the microphone to receive bone-transmitted voice sounds made by the user during use of the headset.
