ABSTRACT:
A transceiver adapted for mounting upon straps of a gas mask or a helmet is smaller in size and weight, and therefore excellent in fittingness, which makes handling of the transceiver less cumbersome even when a user wears the gas mask or the helmet. The transceiver enables a user to communicate with his or her communication partner even when the user does his or her own work. In construction, the transceiver (1) has a rotatable casing (2). The casing (2) receives therein a bone conduction speaker portion (3) and a bone conduction microphone (4), and is pivoted to a supporting member (5). The supporting member (5) is provided with engaging means (7and8), which engage with straps (11and12), respectively.
