WIRELESS VILLAGE(RESIDENT) BROADCASTING ABLE TO PREVENT CONFUSION SIGNAL AND BROADCAST IN GROUP

摘要

The present invention relates to a wireless village broadcasting equipment capable of preventing interference and broadcasting by group, the wireless village broadcasting equipment comprising: a transmitter including an input unit for inputting a voice signal which a user wants to send; a transmission control unit for controlling the voice signal input through the input unit to an electrical signal so as to transmit the voice signal by wireless, and a transmitting unit for transmitting the signal controlled by the transmission control unit; and a receiver including a reception control unit including a receiving antenna which receives, by wireless, the electrical signal transmitted from the transmitter such that residents who hear the voice signal can listen to a broadcast, a voice signal circuit for sending the received voice signal, and a speaker provided at the end of the voice signal circuit to send an audible voice signal, wherein the transmitter includes an additional subtone loading unit provided to load a pilot tone onto the voice signal which a user has input through the input unit. Accordingly, interference between the same or similar frequency bands can be prevented and the user can selectively broadcast the voice signal to only targets who need the broadcast.
