Usually a transducer converts a signal in one form of energy to a signal in another.
In human engineering, signals are typically provided by a sensor, and often the original form of a signal is converted to another form of energy using a transducer.
A loudspeaker (or loud-speaker or speaker) is an electroacoustic transducer; a device which converts an electrical audio signal into a corresponding sound.
Consequently, a characteristic physical parameter varies and this variation is reported by means of an integrated transducer that generates the output signal.
Audio signals may be synthesized directly, or may originate at a transducer such as a microphone, musical instrument pickup, phonograph cartridge, or tape head.

A microphone, colloquially named mic or mike, is a device – a transducer – that converts sound into an electrical signal.
A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure.

Vibration powered generators usually consist of a resonator which is used to amplify the vibration source, and a transducer mechanism which converts the energy from the vibrations into electrical energy.
In later electric phonographs (more often known since the 1940s as record players or, most recently, turntables ), the motions of the stylus are converted into an analogous electrical signal by a transducer, then converted back into sound by a loudspeaker.
