In a moving coil loudspeaker, a coil of wire is immersed in an air gap in a magnetic circuit. The magnetic field is “radially” oriented, meaning that its direction is across the gap in the radial direction.

Rice and Edward W. Kellogg at General Electric was important in establishing the basic principle of the direct-radiator loudspeaker with a small coil-driven mass-controlled diaphragm in a baffle with a broad midfrequency range of uniform response.

Johann Philipp Reis installed an electric loudspeaker in his telephone in 1861; it was capable of reproducing clear tones, but later revisions could also reproduce muffled speech. Alexander Graham Bell patented his first electric loudspeaker (a moving iron type capable of reproducing intelligible speech) as part of his telephone in 1876, which was followed in 1877 by an improved version from Er… NettetLoudspeaker engineers focus on the motional part of the overall loudspeaker impedance. They choose to model this motional impedance as a parallel RLC circuit such that: Comparing these two equations, the values of R, L, and C in the parallel circuit that models the motional impedance must be:

Nettet14. des. 2024 · Moving Coil Microphone works on Faraday’s law of electromagnetic induction, which states that, “when a conductor moves in a magnetic field, it cuts the flux line and an emf is generated.” Therefore, Electro-dynamic microphones are also called as Electro-magnetic microphones.
