The design of intelligent music system based on Internet of Things

With the rapid development of smart home, a cheap and intelligent music system which is easy to install and operate will be of great concern. In this paper, the STM32F407ZET6 is used as micro-controller core of the control by the music system. Audio decoding module, SD card, Bluetooth audio receiver, radio module, audio source selection module, po-wer amplifier, etc. are included in this system. The intelligent music system can achieve multi sound source input function and selection of the music playback mode including local music playback in SD card, mobile phone APP control by WIFI wireless module, handheld devices with Bluetooth. With high fidelity amplifier circuit design, sound quality is pure. Also it has the radio function for users. After integrated debugging of software and hardware, the music system can meet the requires of the design.
