Speaker Microphone Circuit The circuit is designed to be used with an operating voltage between 6 and 12 volts dc. The first transistor operates in common base mode. This has the advantage of matching the low input impedance of the speaker to the common base stage, and secondly has a high voltage gain. The second stage is direct coupled and operates in emitter follower. Voltage gain is slightly less than unity, but output impedance is low, and will drive long cables. Simple Microphone to Speaker Amplifier Circuit Diagram In this circuit, we learn to build a simple Microphone to Speaker system, in which input sound is given to the MIC and we hear the amplified version from the speaker.
