Thermal Failure Modes of Loudspeakers

  • John M. Eargle

Abstract

In professional applications such as sound reinforcement the dominant failure mode of a loudspeaker driver is due to excess heating of the voice coil. Often there is a chain of events in which heating causes expansion of the voice coil, with subsequent rubbing of the voice coil against the top plate and electrical shorting of the voice coil windings.
