The application documents and the reply to the audit inquiry show that:
(1) The iteration of products in the consumer electronics industry is fast. During the reporting period, the issuer's sales revenue to Xiaomi, Flextronics, Shenzhen Transsion Holdings Co.Ltd(688036) and other customers declined due to the product iteration of downstream customers.
(2) The products sold by the issuer to Lianchuang Hongsheng and Quancheng electronics are mainly used in Huawei headphones and headphone socket converters. Affected by the decline of Huawei's mobile terminal business, the issuer's related revenue fell to 17.272 million yuan in 2021 from 678191 million yuan in the previous year.
(3) In 2021, affected by the global chip supply shortage, the delivery volume of Wingtech Technology Co.Ltd(600745) connector products to the issuer decreased, and the amount of the issuer's realized sales revenue decreased by 11.34% compared with the previous year.
Please the issuer:
(1) Explain the technical iterations of each main product, the relevant technical reserves and R & D of the issuer, the projects under research between the issuer and each main customer, analyze the continuity and stability of cooperation with main customers, further analyze the impact of product iterations of downstream customers on the sustainability of income growth of the issuer, and whether the issuer has the risk of losing important customers.
(2) Quantitatively analyze the impact of Huawei mobile terminal business decline, chip shortage and other factors on the issuer's income stability and sustainable operation ability, explain whether there is a significant decline risk in future performance, and supplement relevant risk tips.
The sponsor and the reporting accountant are requested to express clear opinions.

1、 Explain the technical iterations of each main product, the relevant technical reserves and R & D of the issuer, the projects under research between the issuer and each main customer, analyze the continuity and stability of cooperation with main customers, further analyze the impact of product iterations of downstream customers on the sustainability of income growth of the issuer, and whether the issuer has the risk of losing important customers.
(I) explain the technical iteration of each main product, the relevant technical reserves and R & D of the issuer, and the projects under research between the issuer and each main customer
1. Technical iteration of main products
The company is mainly engaged in the R & D, production and sales of precision connectors. Its products are mainly used in 3C fields such as mobile phones and their peripheral products, intelligent wearable devices and computers, forming a product system dominated by connectors and supplemented by precision mechanism parts. The company's connector products are composed of card connectors, I / O connectors, headphone connectors, battery connectors and other connectors, among which card connectors, I / O connectors and headphone connectors are the company's main connector products.
In recent years, with the increasing demand for intelligent, lightweight and high-speed consumer terminal products, the official commercial use of 5g and the rapid development of technology, the corresponding connector products are also constantly updated and iterated. Among them, the combination of "three out of three" card holder products and "two out of three" card holder products plus single card holder forms an iteration, and the type-C product forms an iteration for micro USB products and headphone connector products.
In order to meet the demand of "single seat and dual seat" card in the industry, it is more difficult to realize the combination of "single seat and dual seat" card in 2017. In comparison, the production process of "three out of three" split card holder is more concise and competitive, thus gradually forming a technical iteration of "two out of three" card holder products plus single card holder combination. With the popularization of 5g communication technology, in order to further reduce the area occupied by card connectors on the main board, laminated card connectors and other products in card connectors will become a new direction of card connectors. During the reporting period, through continuous R & D investment, the company developed a number of "three out of three" card holder and laminated card connector products and achieved mass production.
In terms of I / O connectors, the traditional I / O connectors include USB type A and B, micro USB, HDMI, etc. in recent years, with the advantages of strong scalability, bidirectional power supply, fast transmission rate and high transmission power, support for positive and negative plug-in on both sides, lighter interface and so on, the type-C connector is gradually becoming the mainstream interface of consumer electronics, and is expected to fully replace the traditional I / O connector. With the popularity of type-C interface of consumer electronic products, the market demand for type-C connector has increased significantly.
In terms of headphone connectors, with the popularity of type-C interface, headphone connectors have been gradually replaced by type-C connectors in the high-end smartphone market.
The company keeps up with the development trend of the industry and the needs of customers, maintains the continuous renewal and iteration of products, and has formed a diversified product series and a complete product specification structure, which meets the diversified needs of customers and enhances customer stickiness.
