Mp3 speaker with RDA5851s

Today I’ve disassembled MP3 speaker and noticed RDA’s chip inside.Very interesting solution. Speaker itself provided powerfull bass until it burnt out. I will dig deeper later to understand what part caused the problem. This company’s products include RDA3560M satellite downconverter IC which I am interested in. Such products are mainly interesting because they are cheap mass production IC’s. With some effort you can use theirs IC functionality and significantly reduce costs.
