摘要
PURPOSE: A bone conduction wireless communication device is provided to transmit a message through bone conduction inside a safety helmet by integrating a bone conduction mike and a high-powered speaker in a one body. CONSTITUTION: The bone conduction communication device includes a jack(7) for connecting to a terminal(6) at the end of a cable(10), a PTT switch(1) having a Vox connected in the middle of the cable, and a bone connection mike and a speaker at the other end of the cable. The bone conduction mike unit has a bone conduction mike(2) and an ordinary speaker(3) integrated in one case(C) built-in, and an ear phone(4a) connected with the case(C) with a rubber tube(4).
