GY8700 Bluetooth serial voice chip supports Bluetooth 5.0 protocol MP3 music decoding

In recent years, the market and demand for intelligent voice products have continued to expand. Relevant data shows that the scale of my country’s smart voice market will reach more than one trillion in the future. Driven by market demand, various voice chips have been derived. Among them, Bluetooth voice chip is a common configuration of many smart voice products. Through the Bluetooth voice chip, the device can wirelessly connect to the Internet and realize the function of intelligent voice.
Smart Bluetooth serial port voice processing needs to collect external sounds and transmit the sounds to the chip for voice processing, and then convert the processed information into machine-readable digital codes and output them again for voice feedback. During the transmission process, whether the signal channel is smooth is an important guarantee for the smooth execution of voice processing feedback. Just like water pipes, large-diameter, multi-channel pipes transport water faster and more smoothly. The signal channel is smoother, the transmitted signal and sound quality do not need to be compressed, and the fidelity is naturally higher.
Geyuan Electronics has developed the GY8700 Bluetooth voice chip in response to market development, which uses low-power, high-stability BLE5.2 Bluetooth technology, 6-channel PWM, and fast transmission speed. At the same time, Bluetooth BLE has a “direction-finding function” that can help the device clarify the direction of the Bluetooth signal, thereby accurately positioning the transmission, reducing search time, and providing faster feedback. GY8700 Bluetooth voice chip adopts a new voice algorithm, which has the characteristics of high compression ratio and high fidelity, original sound processing, high recognition rate and accurate feedback.
