People typically use a compact, battery-driven sound device. It's round and has a diameter of 120 millimeters. A rechargeable Li-ion battery with an enormous 1500mAh capacity is inside it, along with a high-performance stereo PWM amplifier that pumps out a strong 2x3W signal. This was simply a rapid undertaking for me, utilizing readily available components, so I'm unable to provide a detailed construction guide. Nonetheless, if you have any inquiries, please don't be reluctant to ask. Additional sources where you might locate the necessary components include: Audio Amplifier Lithium Charger Portable Speaker (diameter of 45mm)
