May be configured to perform Bluetooth wireless communication with the wireless shoulder microphone 120 in the relay zone that the second shoulder microphone communication unit 420 is formed / maintained as a master device. That is, wireless communication with the dongle 110 is performed by the first shoulder microphone communication unit 410, and the second shoulder microphone communication unit 420 is different from the wireless shoulder microphone 120b outside the Bluetooth communication area of the dongle 110. It may be configured to perform Bluetooth wireless communication. In this case, the first shoulder microphone communication unit 410 receives a signal transmitted from the dongle 110 to the wireless shoulder microphone 120b outside the Bluetooth communication zone of the dongle 110 through the first shoulder microphone communication unit 410. The second shoulder microphone communication unit 420 receives a signal transmitted from the wireless shoulder microphone 120b outside the Bluetooth communication zone of the dongle 110 to the dongle 110 through the first shoulder microphone communication unit 410. By transmitting, the relay function can be performed.

The relay shoulder microphone control unit 400 may include the above-described Bluetooth antenna 202, a fitness switch 212, a voice output unit 204, a first shoulder microphone communication unit 410, a second shoulder microphone communication unit 420, and a master. Each component including the / slave selection switch 250 is controlled to perform Bluetooth relay communication.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes and additions within the spirit and scope of the present invention. Additions should be considered to be within the scope of the following claims.
