Abstract

PURPOSE: To obtain a sound effects generating device which is low in actualization cost by equipping the device with a waveform generating circuit A which generates a waveform of basic sounding frequency and a waveform generating circuit B which generates a waveform of modulation frequency, and driving one sounding body with the output of the waveform generating circuit A and driving the other with the output signal of the waveform generating circuit B. CONSTITUTION: The sounding body 4 is driven independently with both the output of the waveform generating circuit A8 which generates the waveform of basic sounding frequency and the output of the waveform generating circuit B9 which generates the waveform of modulation frequency. The waveform generating circuit A8 is supposed to be a microcomputer and the waveform generating circuit B9 is supposed to be a D/A converting circuit. In this constitution, the sounding body 4 is driven independently and divisionally at the basic frequency relatively close to a single frequency and the modulation frequency, and the waveform generating circuits 8 and 9 having those frequencies are easily obtained. Consequently, the actualization cost becomes low.
