trans·duc·er T0315500 (trăns-do͞o′sər, -dyo͞o′-, trănz-)n.1. Physics A substance or device, such as a piezoelectric crystal, microphone, or photoelectric cell, that converts input energy of one form into output energy of another.2. Biology Something, such as a receptor in a cell membrane, that transmits a signal within a cell or from the exterior of a cell to its interior.
[From Latin trānsdūcere, to transfer : trāns-, trans- + dūcere, to lead; see deuk- in Indo-European roots.]transducer (trænzˈdjuːsə) n (Electronics) any device, such as a microphone or electric motor, that converts one form of energy into another[C20: from Latin transducere to lead across, from trans- + ducere to lead]trans•duc•er (trænsˈdu sər, -ˈdyu-, trænz-)
n. a device, as a microphone, that converts a signal from one form of energy to another. trans·duc·er (trăns-do͞o′sər) A device that converts one type of energy into another. For example, the transducer in a microphone converts sound waves into electric impulses, while the transducer in a loudspeaker converts electrical impulses into sound waves.transducerA device that converts one kind of wave signal into another.Thesaurus| Noun | 1. |  transducer - an electrical device that converts one form of energy into anotherelectrical device - a device that produces or is powered by electricityelectro-acoustic transducer - a transducer that converts electrical to acoustic energy or vice versamosaic - transducer formed by the light-sensitive surface on a television camera tubeelectric eye, magic eye, photocell, photoconductive cell, photoelectric cell - a transducer used to detect and measure light and other radiations |

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

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.

or speaker,
device used to convert electrical energy into sound. 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.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. transducerA 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, lightor other signals to or from an electronic signal.transducer (2)Finite State Machine.transducerA 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
transducer [trans-doo´ser] a device that translates one physical quantity to another, e.g., pressure or temperature, to an electrical signal.neuroendocrine transducer a neuron, such as a neurohypophyseal neuron, that on stimulation secretes a hormone, thereby translating neural information into hormonal information.pressure transducer an electronic device that converts pressure (such as blood pressure) into electrical signals that can be recorded graphically and monitored.trans·duc·er (tranz-dū'sĕr), A device designed to convert energy from one form to another.

Biology Something, such as a receptor in a cell membrane, that transmits a signal within a cell or from the exterior of a cell to its interior.transducer Instrumentation A device that transforms one form of energy to another–eg, a photocell that converts light into electrical energy; it is the major component in ultrasonographic devices, and contains an emitting and receiving piezoelectric crystaltrans·duc·er (trans-dū'sĕr) A device that converts energy from one form to another (e.g., from electrical energy into ultrasonic energy). transducer (trans-doo'ser, tranz-, -du') [L. traducere, transducere, to lead across] 1. A device that converts one form of energy to another. The telephone is an example. It is used in medical electronics to receive the energy produced by sound or pressure and relay it as an electrical impulse to another transducer, which can either convert the energy back into its original form or produce a record of it on a recording device. Synonym: probe2. In ultrasonography, an electromechanical device that emits high-frequency sounds and receives their echoes.pulse-echo transducerAn ultrasonic transducer that sends out intermittent (pulsed) signals rather than continuous sound waves and receives the echo signal. Pulsed-wave Doppler ultrasound is used to measure blood flow and the depths from which echoes originate. continuous wave transducerAn ultrasonic transducer that sends a constant and continuing signal that is not pulsed.transrectal transducerA cylindrical ultrasonic transducer inserted into the rectum to evaluate the prostate, rectum, and urinary bladder and to guide prostate biopsy.
