| Musical
instruments are good examples of transducers. The
guitar, for example, is a type of transducer where
the energy of the plucked and vibrating string is amplified by the wood
of the soundboard which is then converted into vibrations in the air which
we perceive as sound. |
Microphones
are another
example of transducers. In this case energy in the
form of sound waves in the air are converted into motions of the diaphram
of the microphone which are in turn converted into fluctuations of electrical
current which can be carried by electrical wiring to amplifiers or recording
and processing equipment. |
