PURPOSE:To utter several kinds of different voices, by giving ground potential to the 1st - the 3rd input terminal. CONSTITUTION:When a ground potential is given only to an input terminal IN3, transistors(TRs) Tr6, TR7 are turned on, an oscillator OSC3 is oscillated, its output is amplified at an amplifier AMP and outputted from a speaker SPK. When a ground potential is given to only an input terminal IN2, the OSC is oscillated, this output is amplified at the AMP and outputted from the SPK. Thus, the voice outputted from the SPK is different depending when the ground potential is given to the input terminal IN2 and to the input terminal IN3. In applying the ground potential to the input terminal IN1, the OSC3 is oscillated, the oscillating output of the OSC3 is amplified at the AMP and outputted from the SPK. Three different kinds of voices are generated in this way. |
