Description

Circuit schematic like in Figure 1 above is Circuit Schematic Simple Electronic Stethoscope using Transistor. Eleccircuits site describe that usually the stethoscope is a medical device that listens to the heartbeat. Which we can make it with the least amount of electronic equipment so easy to make.

The piezo speaker will detect the heart beats. Then, it is amplified by Q1. In combination with R1-R4, VR1 and C1 are amplifiers, As Common-emitter amplifier: The input and output signals both share a connection to the emitter. It can output a response with low frequencies. So the output is connected to the headset with low impedance. To be able to listen to heartbeat. The VR1 will act as a volume adjuster to loud or low.
