This electronic snore-ceasing equipment circuit is composed of power supply circuit, sound control circuit and electrical pulse generation circuit, it is shown in the figure 9-147. The sound control circuit is made of microphone BM, resistors R1-R4, capacitors C1, C2 and transistor V. The electrical pulse generation circuit consists of IC(Y976), resistor R5, potentiometers RP1-RP3, capacitors C3, C5, pulse transformer T and electrodes a,b. After the power supply switch S is connected, GB's 3V DC voltage is filtered by C4, one path is fed to IC, the other path is current limited by R4 and it is as the working power of sound control circuit.
