A movable coil is attached to a large cone. The coil fits over the central post of a cylindrical permanent magnet. If current flows through the coil, the cone will move. If the current varies rapidly, the cone moves in and out, producing the compressions and rarefactions of a sound wave.

WebSep 1, 2024 · The interaction between the fluctuating field of the voice coil and the fixed magnetic field in the gap produces axial forces that move the voice coil back and forth, carrying the diaphragm with it. The faster the audio signal alternates, the faster the diaphragm moves, and the higher the frequency of sound produced. WebHow does sound travel through a speaker? As the electricity flows back and forth in the cables, the electromagnet either attracts or repels the permanent magnet. This moves the coil back and forward, pulling and pushing the loudspeaker cone. Like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.

WebMar 12, 2024 · The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. This cone is held at its edges by an airtight suspension or surround. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound. Web1. As one side of the coil moves up through the magnetic field, a potential difference is induced in one direction. 2. As the rotation continues and that side of the coil moves …
WebThe two magnetic fields created interact, causing force to be exerted. When the current through the coils reverses, the force exerted by the coils will also reverse. The coils are …
