TWS headphones have become one of the fastest growing products among consumer electronics products , and have also become an electronic device that many users must carry when going out. The popularity of TWS headphones has driven the development of related industrial chains, and Bluetooth audio chips are the most important link. Therefore, many original chip manufacturers have joined the layout, and their products continue to iterate and upgrade, promoting the improvement of TWS headphones' performance and enrichment of functions.
Recently, I Love Audio Network disassembled the Besi Bowie E9 true wireless headset and shared its appearance design and internal configuration information for friends. After disassembly, it was learned that its main control chip uses Juxin Technology ATS3019 Bluetooth audio SoC, adopts RISC32 streamlined instruction set structure, built-in large-capacity storage space, supports Bluetooth 5.3 dual mode, low-latency mode, and supports dual microphones, providing support for many functional applications of headphones.
Bowie E9 true wireless headphones have a small and light rounded square design in appearance, making it easy to carry when going out; the headphones are in-ear design with handle-shaped in-ears, and the unique earplugs and the body are presented on the same curve, achieving a seamless fit between the curve of the headphones and the ear canal, providing a comfortable wearing effect. The rectangular headphone handle and silver tail plug also give it a strong texture and high recognition.
Bowie E9 true wireless headphones are equipped with a 10mmPU + titanium composite diaphragm dynamic coil unit, supporting the new generation 5.3 Bluetooth version, providing strong low-frequency sound and stable wireless connection; in-depth call noise reduction effect is mainly used in function, and also supports cross-platform dual-device connection, open cover connection, in-ear detection, instant flash charging, wireless charging, etc., with a comprehensive battery life of 30 hours.
Through disassembly, it was learned that the Besi Bowie E9 charging box has a built-in 400mAh lithium battery, equipped with Siyuan Semiconductor SY8801TWS headphone charging chamber SOC and Vodar NU1680C wireless charging receiving chip, which is used to charge the internal battery, discharge the headphones, detect the entry and exit chamber, data transmission of the charging box and headphones, and upload the charging box.
Bowie E9 headset is equipped with a 40mAh steel case buckle battery, which powers the various functional applications of the headset; the built-in two Ruiqin electronic high-sensitivity MEMS microphone can accurately capture the voice and ambient noise during calls, and is equipped with the main control chip noise reduction algorithm to achieve clear voice call effect.
Bowie E9 main control chip adopts Actions ATS3019 Bluetooth audio SoC, the core adopts RISC32 streamlined instruction set structure, with a main frequency of 200Mhz; built-in ROM, 8Mbits SPI Flash and 216K bytes RAM; integrated power management, supporting lithium battery and DC5V power supply.
Juxin Technology ATS3019 supports Bluetooth 5.3 dual mode, transmitting power up to 10dBm, and receiving sensitivity of -95dBm, effectively improving the stability of audio connection; it also supports low-latency mode, Bluetooth audio signal delay as low as 40ms, and supports dual-microphone ENC call noise reduction, etc.
According to the disassembly of I Love Audio Network, there are currently products under brands such as Lenovo , Rode, Xiaomi , Realme, JBL, Bisi , Bull, Motorola , Xiaodu, Singba , Green Network, NetEase Cloud, Crazy Mi , Himalaya and other brands that have adopted Juxin Technology's Bluetooth audio main control chips.
