 Abstract: The application of Think Wireless SA316 audio wireless module in wireless speakers. SA316 is designed with a high-quality 48K sampling rate voice transmission chip. This wireless speaker solution offers four adjustable power levels, a maximum transmission distance of up to 1.8 kilometers, support for 40 channel adjustments, one-to-many mode, low latency of less than 3ms, and more. SA316 audio wireless module also provides customized services and product certification support.

The demand for wireless speakers in the market continues to grow, driven by consumers' pursuit of portability and improved quality of life. With the widespread adoption of wireless technology, users can easily connect wireless speakers to various audio source devices, making them a common choice for outdoor activities, travel, and social gatherings. The requirements for audio wireless modules in wireless speakers have evolved beyond wireless transmission methods to include higher functionality demands, such as transmission distance, latency, and multifunctional quick-access design modes.

Allow me to provide a brief introduction to a case study featuring the NiceRF SA316 audio wireless module in wireless speakers. The NiceRF SA316 series includes the SA316-TX transmitter module and the SA316-RX receiver module. This solution incorporates a high-quality 48K sampling rate voice transmission chip and supports external PCM/IIS dual-mode digital audio interfaces. Furthermore, the module offers standardized serial interfaces, enabling users to easily configure parameters such as transmission and reception frequencies, sound volume, and microphone gain through serial commands. This versatility makes it well-suited for applications that demand high audio quality.

The wireless speaker solution involves the SA316-TX transmitter module, which connects to an audio input, supporting both line-in and microphone inputs. The SA316-RX receiver module connects to the speaker, enabling effortless wireless audio transmission.
