Specification:
Origin: Mainland China
Size: 106x66x60mm/4.17x2.6x2.36inch
Material: Acrylic
Channel output: 2 channels
Output power: 3W+3W
Power supply voltage: DC 4.2-5v, exceeding 5v will damage the module
Rated current: 1.5A-2A

Circuit function:
The red terminal of the Bluetooth-compatible module is powered by the 5V power supply, the white terminal is the left and right channels of the speaker, the red wire is positive +, and the black is negative -.
As music or other sounds sound, the LED lights will flash and move according to the rhythm of the sound (the speed of the sound).
After successful welding, you can feel the beautiful melody combination of sound and light.
Circuit principle:
The voice-activated LED melody light circuit consists of a power supply circuit, a microphone amplifier circuit, and an LED light-emitting indicator circuit. The power supply uses two batteries.
The MIC converts the sound signal into an electrical signal, which is coupled to Q1 for amplification via C2. The amplified signal is sent to U1, which drives the ED to emit light.
The louder the sound, the brighter the LED and the faster the water flow.
