20140363017 | Signal Receiving Structure of Wireless Microphone - A signal receiving structure of a wireless microphone contains: a host controlled by a RS485 and connecting with a plurality of RS485 receivers via plural signal cables, such that signal receiving ranges of the plurality of RS485 receivers are overlapped so as to expand a total receiving range, and any one of the plurality of RS485 receivers transmits at least one microphone signal back to the host through RS485 remote-control communication interface after receiving the at least one microphone signal, and power is supplied to the plural signal cables from the host, thus expanding using range of at least one wireless microphone. At least one receiving module in the plurality of RS485 receivers receives the at least one microphone signal, acquires a strong one of the at least one microphone signal by using automatic selection, and outputs the strong one of the at least one microphone signal to the host. | 12-11-2014 |
