System Structure

The soundbar receives audio data from the audio source via Bluetooth and transmits it to an external Digital Signal Processor (DSP) through the I2S interface for further processing. Additionally, the Bluetooth Microcontroller Unit (MCU) communicates with the DSP via a UART interface to ensure precise processing and synchronization of the audio signals.
