ABSTRACT:
Loudspeakers are protected against overloading by the inclusion of a magnetic reed switch between each speaker and its driver. The reed switch is operated by a sensor associated with the driver. This allows the switch to be operated, and remain operated, whenever the power level from the driver exeeds a prescribed value which could otherwise damage the speaker.
