4. The hardware design of the bluetooth speaker system is realized.

5. The software design and test of the system are carried out. First, the software development platform of the bluetooth module is introduced. Then the software design process is expounded.

6. In order to further improve the sound quality, the MP3 compression algorithm will be added to process the voice data. The full name of MP3 is the MovingPicture ExpertsGroupAudio Layerlll. One of the more popular digital audio coding and lossy compression formats today, it is designed to greatly reduce the amount of audio data, while for most users the playback quality is not significantly different from the original uncompressed audio. To put it simply, MP3 is an audio compression technology. Since the full name of this compression method is called MIPEG Audio Layer3, people call it MP3 for short. MP3 uses the technology of MPEGAudioLayer3 to compress music into a file with a smaller capacity at a compression ratio of 1:10 or even 1:12. In other words, it can compress the file to a smaller degree with little loss of sound quality. And it also maintains the original sound quality very well, so the MP3 compression algorithm is also an important research object. www.bjbjaudio.com

Expected Goals of Bluetooth Speaker Research
The goal of Bluetooth speaker research is to realize real-time transmission of audio data between the source and sink through Bluetooth; real-time conversion of the audio signal received by the sink through digital-to-analog conversion equipment, and real-time playback through amplifying equipment. Mainly to realize an application model of bluetooth technology bluetooth speaker. On top of this, the protocol specification of bluetooth communication technology and the method and steps of bluetooth application development are discussed comprehensively, and the new technology of bluetooth wireless access is mastered. This lays a solid foundation for further in-depth research on bluetooth technology and development of bluetooth products in the future. In addition, you can discuss the design and master the embedded development steps and processes. www.bjbjaudio.com              <a style="opacity:0.0;color:#ffffff">true wireless twin speakers</a>
