Simple speaker relay delay circuit
Webb18 aug. 2024 · You can increase the value of C2 to add more turn on delay. Q2 drives the relay that connects the output of the amplifier to speaker. When a DC offset is detected on the output, Q1 will turn on and will cause the Q2 to turn off and will deactivate the relay that connects the speaker to amplifier. Update: Corrected the orientation of D3. Webb22 jan. 2010 · The time delay relay circuit described here is intended for this purpose.
