Description:

The potentiometer adjusts the volume, with a switch, it is convenient to control the volume, which is very suitable for DIY speakers.

If it is a metal box, the Bluetooth antenna needs to be led out.

The copper DC connector is used, which can withstand high current and does not generate heat.

470UF35V solid, to ensure the power storage and heat dissipation capacity, providing stable and continuous is the prerequisite for good sound quality.

The 5.0 Bluetooth version has higher transmission efficiency and longer transmission distance.

Note:

Tip:Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power. The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the greater the ohms of the speaker, the lower the relative sound power, please pay attention!
