ドレス電話のリンガースピーカ回路。 In a cordless telephone consisting of a base unit connected to a telephone line and a handset that can send and receive calls via wireless communication, there is a battery built into the handset, a mode switch that switches the handset to a standby state and a talking state, and a mode switch that switches the handset to a standby state and a talking state. A receiving circuit receives power from the battery when in a call state and enters an operating state and receives a calling signal transmitted from a base unit and a voice signal from a caller, and a receiving circuit receives power from the battery during a call state. a transmitting circuit that transmits the voice signal of the caller to the base unit when the signal is supplied and becomes operational; an interlocking switch that operates in conjunction with the mode switch; a speaker that emits a sound, and a microphone that converts the speaker's voice into an electrical signal when in a call state, and when in a standby state, a calling signal is applied to the microphone by switching the interlocking switch. A ringer speaker circuit for a cordless telephone, characterized in that it emits a ringing tone from a phone.
