Abstract

PURPOSE:To generate a call tone with high efficiency without power consumption by providing an amplifier switch supplying power to an amplifier in a talking circuit so as to allow the talking device to cause howling in response to a call signal from an external line in the standby state. CONSTITUTION:A moving contact (a) of a changeover switch 6 is connected to the 1st contact (b) in the standby state, and the 2nd amplifier switch 52 is turned off. In turning off a call switch 34, a howling circuit 40 is operated to generate howling and a large sound is caused from a speaker 1. In hooking up a handset 21, since a hook switch 30 is switched on, the moving contact (a) of a changeover switch 6 is thrown from the 1st contact (b) to the 2nd contact (c) in interlocking therewith and the 2nd amplifier switch 50 is turned on. Thus, handset talking is attained by a microphone and speaker of the speech network.
