1. The over - current protection device is used, making it durable and having a long service life. 2. In the high - frequency part, well - known non - inductive capacitors are connected in parallel, and a high - power capacitor - free design is adopted. In the low - frequency part, an inductor is used for conversion to achieve clear and full sound effects. 3. The PCB board uses a fire - resistant board, and the thick copper layer can withstand current. 4. Polypropylene film frequency - dividing capacitors and high - temperature - resistant wire inductor coils are used to ensure the carrying power and long - term durability, and the sound quality is very good. 5.
