Abstract

A portable cordless telephone set for outputting various types of discrimination sounds, in radio communication with a base unit, and having a telephone transmission and reception portion. The portable cordless telephone set includes a sound generation control circuit having at least one microcomputer and receiving a discrimination sound request from the telephone transmission and reception portion; a clock generation circuit generating an operation clock of the sound generation control circuit; a sound generator generating sound having different sound pressures in response to different resonant frequencies, one of the resonant frequencies being adjacent to a frequency of the operation clock; a frequency divider circuit providing at least one divided frequency signal; a switch circuit selectively outputting a signal from the clock generation circuit and the frequency divider circuit; and a timing control circuit outputting an ON/OFF timing signal of the frequency signal received from the switch circuit to the sound generator. The sound generation control circuit energizes the switch circuit and sends a command to the timing control circuit in response to the received discrimination sound request.
