Bluetooth audio SoC solution parameters and product areas

Sound chips can be used in many different fields and have an interactive impact on consumer culture, and sound chips are the easiest to observe among them. They are also an area rich in product types, related materials, and cutting-edge information about cutting-edge industries. Through sound chip R&D and production factories, we can see the interconnection between consumers and consumer products from at least two dimensions: On the one hand, sound chips and electronic products are closely connected, and consumers can learn from the development of electronic products. Benefiting from it, it also contributes some creativity to the field of electronic products; another aspect is its connection and inspiration with popular music and mass consumers.

In the consumer field, Geyuan Electronics has developed mature Bluetooth audio SoC solutions mainly for products such as true wireless headphones, pocket English machines, and Bluetooth ceiling speakers. The following introduces the specific parameters of the plan and the services we can provide.
