This circuit is a circuit diagram to convert the speaker into the microphone. In principle When sound waves fall on the diaphragm of a speaker, there will be fluctuations in the coil and the induced voltage will be no small proportion. This induced voltage is usually very large and useful low. Here, the low voltage circuit using a transistor amplified to produce a reasonable output
