Introduction to the acoustic design, manufacturing, construction and installation of the full acoustic chamber and the on-site test and acceptance of Chongqing Hongxi Technology Co., Ltd.

Chongqing Hongxi Technology Co., Ltd. was established in August 2010. The company's main business is the design, research, development, production and sales of electronic components, high-precision electronic wire components and micro electroacoustic devices. The company's products mainly include extremely thin coaxial components, extremely thin Teflon wire components, other high-precision electronic components, micro speakers and soft material bonding, etc., which are mainly used in the consumer electronics field, mainly laptop computers.

Since 2015, the company has been recognized as a "high-tech enterprise", and has successively won the honorary titles of "Innovative Advanced Enterprise in 2017", "Advanced Enterprise in Open Economy in 2018", "Key Industrial Enterprise in Changshou District, Chongqing in 2020", "Special Industrial Contribution Enterprise in Changshou District, Chongqing in 2021" and won the honorary titles of "Specialized, Special and New" Small and Medium Enterprises in Chongqing in 2021.

Guangzhou Danpin Artificial Environment Technology Co., Ltd. is composed of a team of acoustic experts and professional engineers who have been engaged in research on various acoustic technology for many years at home and abroad and have rich theoretical and practical experience. It has its own office building and factory. The factory has an acoustic laboratory that meets CNAS standards, which can monitor the acoustic technical indicators of its own products and conduct external acoustic testing services. Through the hard work of the Danpin team and the continuous innovation and development, the acoustic laboratory it designs, produces and installs has products with accurate technical indicators, green and environmentally friendly, durable quality, beautiful appearance and high technological content.

The full ablative chamber is not only a special laboratory for acoustic testing, but also an important part of the test system. In fact, it is also one of the acoustic testing equipment, and its acoustic performance indicators directly affect the accuracy of the test.
