Abstract

PURPOSE:To generate different frequencies of signals through one sound piece element, by combining two types of remote control signals from a remote control signal generating circuit having the fundamental wave and a remote control signal generating circuit using a multiple or fraction of this frequency. CONSTITUTION:In a remote control signal generator TX, when a push button S2 is depressed, a signal in the fundamental frequency of audio piece oscillator F-1 is oscillated with transistors (TRs) Q9 and Q10, this signal is amplified at a TRQ11 and applied to a speaker SP. When push buttons S2, S2 are depressed at the same time, a multiplication circuit of diodes D11, D12 is connected to the TRQ11, and the speaker SP produces a signal mixed in the fundamental and double frequency of the oscillator F-1. When this speaker SP is coupled to a handset to a telephone set, the fundamental wave and a multiple or a fraction of frequency taking common the major part of the oscillation circuit can be used as the 2nd control signal without using two different signals, allowing to make possible the control of complicated running and stop for a reception tape to be listened from a remote location.
