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.

well blogger01, term transducer is commonly used in two senses; the sensor, used to detect a parameter in one form and report it in another (usually an electrical or digital signal), and the audio loudspeaker, which converts electrical voltage variations representing music or speech, to mechanical cone vibration and hence vibrates air molecules creating acoustical energy. No transducer is 100-percent efficient; some power isalways lost in the conversion process. Usually this loss is manifested in the form ofheat. Some antennas approach 100-percent efficiency. A well-designed antennasupplied with 100 watts of radio frequency (RF) power radiates 80 or 90 watts in the form of an electromagnetic field.A few watts are dissipated as heat in the antenna conductors, the feed lineconductors and dielectric, and in objects near the antenna. Among the worsttransducers, in terms of efficiency, are incandescent lamps. A 100-watt bulb radiates onlya few watts in the form of visible light.

A transducer is an electronic device that converts energy from one form to anotheris .Common examples include microphones, loudspeakers, thermometers, position and pressure sensors, and antenna.

Efficiency is an important consideration in any transducer.Transducer efficiency is defined as the ratio of the power output in thedesired form tothe total power input.

well, A device that converts variations in one energy form into corresponding variations in another, usually electrical form. Measurement transducers or input transducers may exploit a wide range of physical, chemical, or biological effects to achieve transduction, and their design principles usually revolve around high sensitivity and minimum disturbance to the measurand, that is, the quantity to be measured. Output transducers or actuators are designed to achieve some end effect, for example, opening of a valve or deflection of a control surface on an aircraft. Actuators, therefore, normally operate at high power levels. The term sensor is often used instead of transducer, but strictly a sensor does not involve energy transformation; the term should be reserved for devices such as a thermistor, which is not energy-changing but simply changes its intrinsic electrical resistance in response to changes in temperature.

well, Transducer- changes electrical motion into mechanical motion

in electronics there is capacitors,inductors,transform ers,t ransistors,resistors
for using electrical motion

What would be a capacitors,inductors,transform ers,t ransistors,resistors
for mechanical motion? this is my problem because i don't know what
a capacitors,inductors,transform ers,t ransistors,resistors is for mechanical
motion?

How can i use this mechanical motion to get phase shifting like electrical motion with a capacitor or with a inductor?
