After more than a month of preparation and careful screening in the early stage, the National Tell Laboratory entrusted by the Ministry of Industry and Information Technology finally selected and invited more than 20 industry giants, including the representative enterprises of the mobile phone chip industry Texas Instruments, Onsemi Semiconductor, and Huiding Technology; Leading domestic mobile phone companies such as Huawei, OPPO, VIVO, Lenovo, Meizu, Sharp, Qiku, etc. (ranking in no particular order); Jiahe Acoustics, a representative of the acoustic industry;

In recent years, the USB type-C interface connection technology has developed rapidly, and its high-speed data transmission and convenience of forward and backward insertion operations have quickly gained the favor of consumers, further shortening the product upgrade cycle.

The earphone products based on USB type-C interface connection technology, due to the lack of unified national standards, are developed and produced by various chip and mobile phone companies according to their own enterprise standards. As a direct result, the type-C interface earphones of brand A phones cannot be used on brand B phones, resulting in poor compatibility between companies and generations, and inconsistent considerations for future expansion of functions, It greatly restricts the development of the industry and consumer experience.

As a forward-looking enterprise in the research, production, and sales of USB type-C interface connection technology in China, we closely monitor the relationship between standard formulation, product research and development, certification testing, and sales. We actively undertake industry responsibilities, actively communicate with the Ministry of Industry and Information Technology and the Guangdong Wire and Cable Industry Association, organize upstream and downstream enterprises to participate in the grand event, and focus on building the industry standard framework for type-C interface earphones, regulating and guiding the healthy development of type-C interface earphones.

The meeting was chaired by Mr. Liu Wei, Director of the Taier Laboratory of the Ministry of Industry and Information Technology. Director Liu introduced the current development status, practical problems encountered, and future prospects of type-C interface headphones to technical representatives of various enterprises. For example, type-C interface earphone technology not only transmits sound, but also has the function of identifying personal sensing information such as ID, pulse, and blood pressure in the future, becoming a reasonable carrier for personal health management.

From the perspective of consumer applications, we shared the State of the art of the usb type-c interface and its forecast for the future development trend of the industry, and started the discussion session of this meeting. Chip manufacturers, mobile phone manufacturers, acoustic manufacturers, and connector manufacturers in the industry raised their own views and questions from the signal transmission, compatibility, energy consumption classification, headset add-on functions, and other aspects of the type-c interface headset. The attending parties had a heated discussion and ultimately clarified the overall goal of formulating industry standards for type-c interface earphones: to use type-c interface to transmit audio as the main object, with other necessary content, and to formulate and publish standards in stages and products, ultimately forming a unified market standard, solving compatibility issues, and promoting the healthy development of the industry.

The formulation of industry standards is the cornerstone of the steady and rapid development of the industry. We believe that through this conference, we can build a friendly interactive platform for the development of USB type-C interface earphone technology, promote communication among all parties, and Guangjiayuan Electronics is willing to lead the development of technology with peers and upstream and downstream industries, huddle together for warmth, and enhance the competitiveness of the entire industry in the international market, so that the industry can quickly occupy the technological highlands of foreign markets, Provide a pleasant consumption experience for global consumers.
