Moving coil loudspeaker gcse
Nettet1. sep. 2024 · When a driver is producing a loud sound, the ends of its voice coil can momentarily leave the magnetic field in which the coil sits. This robs the driver of its ability to faithfully move back and forth in response to the drive signal, again changing the music’s dynamics and creating distortion. NettetThe loudspeaker uses a coil which can slide backwards and forwards over the central pole of a circular permanent magnet. The coil is joined by the brown bars to a paper …
