transducer

transducer, device that accepts an input of energy in one form and produces an output of energy in some other form, with a known, fixed relationship between the input and output. One widely used class of transducers consists of devices that produce an electric output signal, e.g., microphones and photoelectric cells. Other widely used transducers accept an electric input, e.g., loudspeakers, light bulbs, and solenoids. The term transducer is sometimes applied to devices producing an output in the same form as their input, e.g., transformers and filters.

transducer

Device that converts one form of energy to another. A microphone is an acoustic transducer, converting sound waves into electrical signals. Different types of transducers act on heat, radiation, sound, strain, vibrations, pressure, and acceleration; they may output mechanical, electrical, pneumatic, or hydraulic signals. Examples include strain gauges, loudspeakers, photocells, transformers, and thermocouples.

transducer

A device that converts one energy into another. There are myriad types of transducers; for example, a read/write head converts magnetic energy into electrical energy and vice versa. A loudspeaker converts electronic signals into air pressure, and a microphone does the reverse. An antenna converts electronic signals into electromagnetic waves and vice versa.
