A
speaker driver is an individual
transducer that converts electrical energy to
sound waves, typically as part of a
loudspeaker,
television, or other electronics device. Sometimes the transducer is itself referred to as a
speaker, particularly when a single one is mounted in a
speaker enclosure or as surface-mounted device (as in a wall-mounted speaker,
car audio speaker, and so on). There are many different types of speaker drivers. The most common ones are the
woofer,
mid-range and high-range
tweeter, as well as bass-range
subwoofers, which are very common. Less common types of speaker drivers are
supertweeters and
rotary woofers.
