transducer, device that accepts an input of energy energy, in physics, the ability or capacity to do work or to produce change. Forms of energy include heat, light, sound, electricity, and chemical energy. Energy and work are measured in the same units—foot-pounds, joules, ergs, or some other, depending on the

One widely used class of transducers consists of devices that produce an electric output signal, e.g., microphones microphone, device for converting sound into electrical energy, used in radio broadcasting, recording, and sound amplifying systems. Its basic component is a diaphragm that responds to the pressure or particle velocity of sound waves. .....

It consists essentially of a thin flexible sheet called a diaphragm that is made to vibrate by an electric signal from an amplifier. .....

The term transducer is sometimes applied to devices producing an output in the same form as their input, e.g., transformers and filters. transducerDevice 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.transducer any device, such as a microphone or electric motor, that converts one form of energy into another transducer [tranz′dü·sər] (engineering) Any device or element which converts an input signal into an output signal of a different form; examples include the microphone, phonograph pickup, loudspeaker, barometer, photoelectric cell, automobile horn, doorbell, and underwater sound transducer. transducer A device which converts power in one kind of system to power in another form, e.g., a loudspeaker which converts electric power to acoustic power.
