\nA microphone converts sound waves into electrical signals.
\n<\/section>\n
\n– A microphone is a transducer, a device that converts one form of energy into another.
\n– Its function is to capture sound (which consists of variations in air pressure) and transform it into a corresponding electrical voltage or current signal.
\n– Different types of microphones use different principles (e.g., electromagnetic induction in dynamic microphones, capacitance change in condenser microphones) to achieve this conversion.
\n– The electrical signal produced by a microphone can then be amplified, recorded, or transmitted.
\n<\/section>\n
\nConversely, a loudspeaker or headphone is a transducer that performs the opposite function: it converts an electrical signal into sound waves.
