In acoustics and audio engineering, the word is used as a general label for transducers that either transform acoustic pressure into an electrical signal (receivers) or convert electrical energy into acoustic pressure (emitters).
Common examples include microphones, which translate sound waves into electrical signals; loudspeakers and earphones, which produce
Operating principles vary. Dynamic microphones and loudspeakers rely on electromagnetic induction between a moving diaphragm and
