Sound and light double control switch socket electrical circuit diagram

The circuit illustrated includes a sound transducer sensing switch, an electrical light control switch, an SCR control circuit, a vocal music circuit, and an AC step-down rectifier circuit.

The circuit comprises several interconnected components that serve distinct functions, allowing for a versatile application in electronic systems. The sound transducer sensing switch utilizes a microphone or similar device to detect sound levels, triggering the subsequent circuits based on the intensity of the sound. This feature is particularly useful in applications where user interaction is required without physical contact.

The electrical light control switch operates as a relay or direct control mechanism for lighting systems. It can be activated by the output from the sound transducer, allowing for lights to be turned on or off in response to sound stimuli. This functionality is beneficial in environments where hands-free operation is desirable, such as in smart home systems or accessibility devices.

The SCR (Silicon Controlled Rectifier) control circuit plays a critical role in managing power delivery to the light control switch. By using SCRs, the circuit can handle high voltage and current loads while providing precise control over the power flow. This allows for dimming functions or on/off control of lighting based on the sound input.

The vocal music circuit is designed to process audio signals, amplifying and shaping them for output. This circuit may include components such as operational amplifiers and filters to enhance sound quality and ensure that the output is suitable for driving speakers or other audio devices.

Lastly, the AC step-down rectifier circuit converts high-voltage AC input into a lower voltage DC output, making it suitable for powering the other components in the circuit. This stage typically involves a transformer to reduce voltage levels, followed by a rectification process using diodes to ensure the output is in a usable DC form.

Overall, this circuit design integrates multiple functionalities, making it suitable for various applications that require sound detection, light control, audio processing, and power management. Circuit as shown, it is by the sound transducer sensing switch/electrical, light control switch, SCR control circuit, vocal music circuit and the AC step-down rectifier circuit .
