Earth Mountain (Suzhou) Microelectronics Technology Co., Ltd. (hereinafter referred to as the "Company" or "EM") Changshu digital MEMS speaker chip production base was officially opened and completed on the morning of October 20, 2023. The company is very honored to invite Professor Yan Yuepeng, Director of the Electronic System General Research Office of the Institute of Microelectronics, Chinese Academy of Sciences, Director of the Kunshan Institute of Microelectronics, Chinese Academy of Sciences, and Executive Dean of the School of Functional Materials and Intelligent Manufacturing, Suzhou Campus, Nanjing University, and Executive Director of Jiangsu Acoustic Industry Technology Innovation Center Professor Lu Minghui, deputy director, and Mr. Danny Lewin, president of Audio Pixels, the company’s long-term partner, came to attend the opening ceremony of the packaging factory.
EM is a high-tech company in the semiconductor chip field that focuses on digital MEMS sound-generating chips and integrates product design, process manufacturing, packaging and testing, application research and development, and sales. It is headquartered in Changshu, Suzhou, China. With the strong support of the development zone, EM Settled in Sound Valley Acceleration Center on June 16, 2021. The semiconductor chip industry has always been a high-tech industry that the country focuses on. It has a wide range of applications and involves high-precision technology research and development and the manufacturing of high-precision instrument components. The semiconductor chip speaker industry in which the company is located is an emerging field full of opportunities and booming development, with a wide range of applications and high technical barriers. Taking advantage of the superior development platform of Changshu Sound Valley, the company is fully committed to the in-depth research and development and industrialization of DSR digital MEMS acoustic sensors.
At present, in terms of technology research and development, after multiple rounds of technological innovation and test verification, EM has completed the research and development and packaging process design of the second-generation MEMS sound chip, and successfully produced 3 batches of samples, which can realize small batch tape-out production. The product's DSR algorithm is fully optimized to output an extremely flat frequency response curve, effectively overcoming technical problems such as harmonic distortion and phase distortion.
The packaging factory workshop of the company's MEMS speaker chip production base is a dynamic, thousand-level constant temperature and humidity workshop, and the entire workshop is equipped with an ESD anti-static system. The anti-oxidation all-aluminum honeycomb elevated floor equipped in the workshop provides a loop system with no dead ends for purified air flow. At the same time, the dual-loop temperature and humidity control system allows the temperature and humidity in the workshop to have a more stable output and a precise dynamic range. The advanced and modern structure and high-end production control equipment of the EM packaging factory provide reliable guarantee for higher quality standard wafer packaging. The official opening of the EM Digital MEMS speaker chip production base gives the company full independent capabilities in the design and production of MEMS speakers.
In his speech, Mr. Danny praised China's pragmatic and efficient work efficiency and the construction of high-quality equipment and facilities in the factory. He pointed out that when he came to Changshu this time, he felt very reassured when he saw the EM-related equipment, facilities, production capacity planning and staffing, and firmly believed that the next generation of MEMS digital speakers will be mass-produced very quickly and promoted globally. Be confident about the future.
Professor Yan Yuepeng delivered a wonderful speech at the opening ceremony, pointing out that Earth Mountain's digital MEMS sound generation technology is a new technology across the ages in the field of acoustics. Traditional speakers are large in size, high in cost, and digitization and arraying are big problems. Digital MEMS speaker chips have brought a revolution in acoustics, hardware, and processing, truly achieving high-quality wide-area sound quality from low frequencies to high frequencies. , and achieved miniaturized components manufactured on silicon through digital processing. This chip has huge advantages in mobile phones, automobiles, digital silencers, voice control of home appliances, and different applications in different fields. The prospects and market of digital MEMS sound technology are very broad. It is hoped that the large-scale mass production of EM digital MEMS speaker chip production base will bring about a new acoustic revolution.
Professor Lu Minghui said in his speech that when he first came into contact with the Earth Mountain brand, he knew that its goals were lofty and its heart was far away. It did not take mountains and rivers as far away, but started with the stars, morning and sea, aiming to plan the entire digital audio era. Great future. It is a huge revolution in the audio industry. We hope that Earth Mountain’s audio technology will allow humans to hear better sounds and lead to a better life. Professor Lu, on behalf of the Suzhou International Acoustic Industry Technology Research Institute, hopes to develop together with my company in the future technology research and development and industrialization process and win a win-win future.
Ms. Du Haijiang, chairman of Earth Mountain Group, pointed out in her concluding remarks that MEMS pixel speaker technology originated from Audio Pixels, a company with nearly 20 years of digital MEMS research history. We would like to thank Audio Pixels for its hard work in the early stages of creation, and for the friendly cooperation with Audio Pixels to jointly promote and expand the influence of digital MEMS sound technology in China and around the world, and to work together to create a better world for mankind. Extensive audio services. In the future, the company will work together from top to bottom to rapidly promote research and development, production and marketing, so that this new technology can be quickly promoted. He also pointed out that the brighter the prospect, the more hard work must be done. A great cause requires everyone to work together to carry forward the past and open up the future. I hope that all employees of Earth Mountain Company can face the light, uphold the quality of perseverance, exert the spirit of innovation and innovation, work together to achieve great things, and work together for a better future.
