Soundbars have become a popular choice for modern home entertainment systems due to their minimalist design and exceptional audio quality. Realtek provides a Bluetooth solution for soundbars that offers outstanding compatibility and seamless integration with various third-party DSP solutions, giving customers greater flexibility. The solution provides end-to-end technical support covering Bluetooth RF, audio encoding, and DSP interfaces, and has already been implemented in numerous products, passing multi-generation validation. Leveraging this mature solution, customers can fully streamline their product development processes and efficiently bring high-quality soundbar products to market.
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.
Application Scenario
Advantages of Solution
Supports simultaneous connection to two Bluetooth devices, allowing one device to control audio playback on the other, delivering a flexible user experience.
Seamlessly compatible with various third-party DSP solutions, ensuring high interoperability.
Provides comprehensive technical support spanning from Bluetooth RF and audio encoding to DSP interfaces, significantly shortening development cycles and accelerating time to market.
The product has been successfully mass-produced in multiple models and validated through generations, demonstrating exceptional stability and reliability.
