Although the growth of the consumer market has been prominent in the past two years, the sales volume of TWS headphones has remained steady growth. On the one hand, due to the changes in consumer habits, the market penetration rate of TWS headphones has continued to increase. On the other handThe continuous evolution and change, its small and convenient appearance and high -quality, low -delay audio effect also brings users a better wearing experience.In this context, more and more headphone manufacturers have begun to deploy TWS headphones.In order to accelerate the design of TWS headsets, Da Lianjia launched the TWS headset solution based on Dafa Technology AB1565 chip. This solution supports MCSYNC and ANC technology to provide users with clearer audio experience.

AB1565 is a TWS Bluetooth headset-specific chip. It supports Bluetooth 5.3 and LE audio certification. It is equipped with ARM Cortex-M4F application processor, which can achieve high performance and low power consumption.And the built -in Tensilica Hifi Mini processor, realize the I/O peripheral control, protocol stack and DSP processing function of AB1565.In terms of features, the chip integrates the function of mixed -dazzling noise elimination (ANC), which improves the voice call quality of headset products.In addition, AB1565 also supports Airoha MCSYNC (multi -broadcast synchronization) technology, allowing headphones to seamlessly switch between left and right ear, with a balanced sound and low delay effect.

In addition, AB1565 also supports the development of voice assistants. For this application, Dafa Technology provides software development tools and Android and iOS APP development references.In addition to applying on TWS headphones, AB1565 can also be used in the design of applications such as stereo headphones, Bluetooth speakers, Bluetooth speakers.And thanks to the high integration of AB1565, the peripheral circuit required for the overall design is quite simple.For peripheral circuit design, Dafa Technology also provides detailed design guide, including schematic diagrams and PCB design to accelerate customer development.
