electro-acoustic transducer

David Tudor's electronic score for the dance has been described as being performed with a forest of electro-acoustic transducers.

The term tonpilz or "acoustic mushroom" may refer to a certain type of underwater electro-acoustic transducer.

Artificial mouth: an electro-acoustic transducer used for the testing of microphones at close speaking distances, and forms part of an "artificial head"

This pulse of sound is generally created electronically using a sonar projector consisting of a signal generator, power amplifier and electro-acoustic transducer/array.

A Fessenden oscillator is an electro-acoustic transducer invented by Reginald Fessenden, with development starting in 1912 at the Submarine Signal Company of Boston.

Generally, the electro-acoustic transducers are of the Tonpilz type and their design may be optimised to achieve maximum efficiency over the widest bandwidth, in order to optimise performance of the overall system.

Among the vast and often rapid changes that have taken place over the last century of audio recording, it is notable that there is one crucial audio device, invented at the start of the "Electrical Era", which has survived virtually unchanged since its introduction in 1925 - the electro-acoustic transducer, or loudspeaker.
