High-quality Bluetooth speaker design reference

Although the common Bluetooth speakers on the market are relatively cheap, their sound quality is far from satisfactory and cannot meet people's pursuit of high-quality sound. The fundamental reason is that the Bluetooth speaker box is too small and the speaker is too small, resulting in a serious lack of bass; the resonance of the plastic box causes muddy sound; the speaker is too close and the near-field sound is too narrow, etc. This design reference integrates the MaxxAudio sound enhancement chip NPCA110P, which greatly improves the problems of muddy sound, insufficient bass, and narrow near-field sound.
