Transducer

A transducer is a device that converts one form of energy into another. For example, a microphone (transducer) changes sound waves (acoustic energy) into electrical signals, while a speaker does the reverse, turning electrical signals into sound. Transducers are essential in many systems, enabling communication between different types of technology by translating signals into forms that can be processed, stored, or transmitted. They are used in various applications, including medical devices, communication equipment, and sensors, helping facilitate the interaction between the physical world and electronic systems.
