Loudspeaker Protection Circuit is really simple, but the function Loudspeaker Protection Circuit is very important, because the Loudspeaker Protection will provide protection to Loudspeaker and other component. Because if the DC current flowing to the speakers must be disconnected as soon as possible. There are several issues that need to be resolved to ensure that the Safety Circuit Speaker will happen fast enough to stop the loudspeaker so that it is not broke, Loudspeaker Protection Circuit is also used to slow the response to damage.
Sometimes other people just simply uses the fuse but remain less effective, Loudspeaker Protection Circuit also includes mute function, which left the sound off and disconnects the speaker as soon as possible after power is switched off to prevent damage Loudspeaker.
Loudspeaker Protection Circuit Using Speaker relay as shown below. Although the circuit looks simple Loudspeaker Protection Circuit, Loudspeaker Protection Circuit but this principle is the same with the factory-made.
For practical purposes, Loudspeaker Protection Circuit has a low frequency limit of 20Hz, and this mean that the minimum 25ms delay is very important. In fact, the combination of low frequency, and waveform asymmetry on the higher frequency, larger delays are usually required. For this reason, it is important that the Loudspeaker Protection Circuit can be easily modified, to change the initial time delay before the system detects the DC and decided Loudspeaker.

Loudspeaker Protection Circuit be able to detect either polarity DC offset, and become immune to the effect of asymmetric waveform and a low frequency, Loudspeaker Protection Circuit is a common requirement, and it is most prudent to use
Loudspeaker Protection Circuit is simple and works well, and as indicated will not trigger a 30V RMS signal at 5Hz, but operates on 30V DC with 60ms applied, and in 50mS with a 45V supply .
Loudspeaker Protection Circuit is not only for Loudspeaker Protection Circuit also suitable for our needs, such as a symmetrical, and with the input diode as shown, a single detector can be used with several input amps and different time constants for each filter.
