   Single push-button switch for power control / mode selection / volume adjustment, etc.

3. Audio LED Module:
   Equipped with a high-brightness LED (model: 2HGU1722B-V2.0), possibly for audio status indication or visual feedback

4. Amplification Circuit:
   Integrated basic amplification components and signal processing (based on ICs and resistors array)

5. Output Interface:
   Likely supports speaker or headphone connection through solder points or extended terminals

6. PCB Size:
   Approximate dimensions: 100mm x 40mm (estimated from component layout)

7. Applications:
   Portable speakers, DIY audio kits, embedded audio systems
