This is the circuit diagram of a voice operated relay. Utilizing this basic sound activated switch design toggling a system by sound pulse could be very effective not. Schematic of the sound activated switch circuit. Allow a few seconds for the relay to be switched off. If an ecm is used then r1 shown dotted will need to be included. It similar with sound activation switch circuit which will turn on and turn off connect and disconnect the switch depending on the sound input. This sensitive sound operated switch can be used with a dynamic microphone insert as above or be used with an electret ecm microphone. A classic example is operating a radio transceiver while driving a motorcycle. Voice operated switch circuit there are many situations where you need to activate a certain device but you just cannot do it because your hands are busy or just cannot let go. Although you may try to drive and operate the transceiver simultaneously this will distract and is very dangerous.

Voice operated switch circuit there are many situations where you need to activate a certain device but you just cannot do it because your hands are busy or just cannot let go. The output switch of this circuit is act by a relay. When you first connect the supply voltage to the sound activated switch circuit the relay will be energised because of the effect of capacitor c2. This sensitive sound operated switch can be used with a dynamic microphone insert as above or be used with an electret ecm microphone. This is the circuit diagram of a voice operated relay. If an ecm is used then r1 shown dotted will need to be included.
A classic example is operating a radio transceiver while driving a motorcycle. This is the circuit diagram of a voice operated relay. You can increase or decrease the on period by changing the value of c2. Voice operated switch circuit there are many situations where you need to activate a certain device but you just cannot do it because your hands are busy or just cannot let go. The post details 3 simple sound activated relay switch circuits which can used as a module for any system that might be assigned to trigger by detecting some kind of sound pressure level or simply applications such as a voice activated alarm security circuit. When you first connect the supply voltage to the sound activated switch circuit the relay will be energised because of the effect of capacitor c2. Although you may try to drive and operate the transceiver simultaneously this will distract and is very dangerous. The output switch of this circuit is act by a relay. It similar with sound activation switch circuit which will turn on and turn off connect and disconnect the switch depending on the sound input. This sensitive sound operated switch can be used with a dynamic microphone insert as above or be used with an electret ecm microphone.
A higher value results in a longer on period and vice versa. A suitable value would be between 2 2k and 10kohms. A classic example is operating a radio transceiver while driving a motorcycle.
