Abstract
An induction type microphone comprises capacitors C1 to C8, resistors R1 to R4, an inductor L, triodes Q1 to Q2, a microphone body MIC and a Doppler effect sensor IC1. An RD627 Doppler effect sensor module is adopted as the Doppler effect sensor IC1. A first pin and a second pin of the Doppler effect sensor IC1 are connected with an annular antenna W. The third pin and the fifth pin of the Doppler effect sensor IC1 are connected through the capacitor C1. The fourth pin of the Doppler effect sensor IC1 is connected with a power supply VCC. The sixth pin of the Doppler effect sensor IC1 is connected with the base of the triode Q1 through the capacitor C2. The collector of the triode Q1 is connected with the power supply VCC. The base of the triode Q1 is connected with the power supply VCC through the resistor R1. The emitter of the triode Q1 is connected with the capacitor C3, the resistor R2, the resistor R3, the inductor L and the capacitor C6. The capacitor C3 is connected with the ground. The resistor R2 is connected with the microphone body MIC and the capacitor C4. The capacity C4 is connected with the resistor R3 and the capacitor C5. The capacitor C5 is connected with the ground. The capacitor C4 is connected with the base of the triode Q2. The collector of the triode Q2 is connected with the inductor L. The emitter of the triode Q2 is connected with the resistor R4. The resistor R4 is connected with the ground. An antenna TX is connected with the collector of the triode Q2 through the capacitor C7.
