transducer,

device that accepts an input of energyenergy,
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 system of

 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., microphonesmicrophone,
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.

or photocell,
device whose electrical characteristics (e.g., current, voltage, or resistance) vary when light is incident upon it. The most common type consists of two electrodes separated by a light-sensitive semiconductor material.

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.

transducer

any device, such as a microphone or electric motor, that converts one form of energy into another

transducer

(1)
A device for converting sound, temperature, pressure, light or other signals to or from an electronic signal.

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.
