Product Parameters:

Power Supply Voltage: DC 4.5V
Board Size: 53 x 37mm
Model: TJ-56-683
Kit Contents:

Circuit Board: 1 piece
Electronic Components: Various (including resistors, capacitors, diodes, transistors, vibration sensor, etc.)
Soldering Tools: Various (solder wire, soldering iron, etc.)
Product Principle: The circuit includes V1 and V2, which are piezoelectric ceramics. When they are subjected to vibration, they generate an electric current. Conversely, if an AC signal is applied, the piezoelectric plates will vibrate at the same frequency. The speaker, which is a black resonant cavity, is used to amplify the sound. IC2 generates the alarm audio signal.

Piezoelectric Ceramics: V1 and V2 are piezoelectric ceramics. When they experience vibration, they produce an electrical signal, which is amplified by V1 and provided to U1 as a clock signal. When U1 pin 11 receives a clock signal, Q2 outputs a high level, driving IC2 to emit an alarm signal. C1, C2, and R4 form a delay circuit, controlling the alarm to stop after a certain period.
Alarm Signal: IC2 generates an alarm audio signal, driving the speaker to sound and achieve the alarm function.
