回路。 In a wireless telephone consisting of a base unit connected to a wired telephone line and a handset unit that can send and receive calls over the wireless line, there is a switch that switches the handset unit to standby mode or talking mode, and a ringing signal sent from the base unit. and a receiving circuit for receiving a voice signal from a calling party;
A ringer signal detection circuit that detects a ringer signal from the receiving circuit, a low frequency amplification circuit that amplifies the voice signal from the caller and the output signal from the ringer signal detection circuit, and emits only the voice signal from the caller. A ringer speaker that emits only the output signal from the ringer signal detection circuit, and a control circuit that controls the operation of the ringer speaker. A ringer speaker for a wireless telephone, characterized in that when a signal is detected by a ringer signal detection circuit, the control circuit is activated by a ringing signal output from the ringer signal detection circuit, and the ringer speaker is activated. control circuit.
