Abstract
The utility model relates to a transmission device for controlling sounding signal by telephone ringing, which is used for interrupting the sounding signals when a telephone rings. The utility model comprises a housing, an input end, an output end and a control circuit, the control circuit is arranged in the housing, and the control circuit is composed of a rectifying circuit and a switching circuit. When telephone ringing electric current is sent to the rectifying circuit by the input end to be rectified and then sent to the switching circuit, and the switching circuit controls the breaking of the sounding signals by the output end. The utility model has the characteristics of simple circuit and convenient operation.
Description
The utility model relates to a kind of telephone ringer current control sound equipment signal transmitter, is used for interrupting when ring the sound equipment signal.
At present, family uses amusement equipment such as video tape recorder, VCD video disc player, karaoke machine rising, in order to reach good acoustics, often need the volume of sound equipment is opened greatly, at this moment, if there is phone to come in, may can't hear telephone bell, and can not in time receive calls, even when receiving calls, can not hear the other side's talk yet.
The purpose of this utility model is a kind of telephone ringer current control sound equipment signal transmitter of design, utilizes the telephone ringer electric current to control the sound equipment signal, when reaching ring, can interrupt the function of sound equipment signal automatically.
Telephone ringer current control sound equipment signal transmitter includes casing, input/output terminal, control circuit, control circuit is arranged in the casing, control circuit is made of rectification circuit and switching circuit, the telephone ringer electric current is delivered to switching circuit through input to the rectification circuit rectification, by the disconnection of switching circuit to output control sound equipment signal.
