To develop new productive forces, we must not only pay attention to the future of the industry, but also lay out future industries. At present, all parts of Jiangsu are actively implementing the instructions and requirements of General Secretary Xi Jinping and the spirit of the National Two Sessions, seizing development opportunities, increasing innovation, planning and building future industries in advance, and making every effort to cultivate and develop new productive forces.

Jiangsu TV reporter Huang Meng: "The little thing I am holding in my hand is a chip. It is very special and can make sounds. It is the world's first digital MEMS sound chip (MEMS speaker)."

Walking into Earth Mountain (Suzhou) Microelectronics Technology Co., Ltd. located in Changshu, Jiangsu, R&D personnel are preparing for the upcoming mass production of chips. Different from the horn shape of traditional speakers, the MEMS digital sound chip is innovatively based on ultrasonic transduction technology to achieve complete digitization of sound. This disruptive technological change not only allows the sound-generating device to be greatly reduced, but also enables precise control of sound, with full-spectrum, high-fidelity technical advantages.

Li Guixin, head of packaging technology at Earth Mountain (Suzhou) Microelectronics Technology Co., Ltd., said: "If compared with speakers, we have full-frequency coverage from 0 to 20 kHz. A MEMS digital sound chip can realize all the functions of traditional speakers. , it sounds like the layering will be very good.”

Since settling in Changshu, Jiangsu in 2021, Earth Mountain (Suzhou) Microelectronics Technology has basically completed the construction of a chip packaging plant, and plans to officially start chip packaging mass production in June this year. By then, this innovative product will bring new solutions to consumer electronics, medical ultrasonic testing, industrial ultrasonic flaw detection and other fields.

Yang Yiwei, financial director of Earth Mountain (Suzhou) Microelectronics Technology Co., Ltd., said: "Currently, we have orders of US$10 million for MEMS digital sound chips . We also hope that such a new MEMS technology can be experienced by global users to the new revolution in sound, taking everyone into the new world of digital audio.

The acoustic MEMS industry is an emerging industry that has accelerated its development in my country in recent years due to its cross-integration characteristics with many scientific and technological fields. In 2020, Changshu City, based on its own development endowment and existing industrial foundation, identified the acoustic industry as a key industry direction in the future, and "Suzhou·China Acoustic Valley" came into being. Entering today's Sound Valley, in the acoustic testing center with a total investment of more than 60 million, there are 12 laboratories with different functions and advanced technologies, such as fully anechoic, semi-anechoic and reverberation chambers, which can provide various Acoustic Research provides professional testing services. With a series of high-quality supporting facilities including this public technology platform, 176 acoustic industry innovation projects have been launched in Sound Valley, realizing the development of the acoustic industry from scratch to excellence.

Lu Qiangbing, general manager of Suzhou Acoustic Inspection and Testing Co., Ltd., said: "In fact, the scope of acoustics is very large. Because it is combined with many advanced technologies now, it can produce some innovations. There will be some innovations in some aspects of the acoustic field in China. When the 'stuck neck' phenomenon occurs, we need to make better materials and better devices in the field of material acoustics."

While pursuing innovation, Changshu, Jiangsu Province insists on cultivating innovation with innovation, "joins hands" with top domestic acoustics universities and institutions such as the Chinese Acoustical Society and Nanjing University, and introduces a talent team including more than 10 academicians to vigorously develop engineering acoustics and information acoustics. , electroacoustics, medical acoustics and other frontier fields of acoustics. After three years of development, Changshu's acoustic industry has combined with local advantageous industries such as clothing and automobiles to develop three leading directions: marine acoustics, vehicle acoustics, and shock absorption and noise reduction. As of now, there are 268 enterprises that meet designated standards and have achieved an output value of 45.88 billion yuan. In 2023, "Changshu Acoustic Communications Industry Cluster" was successfully selected as a provincial-level small and medium-sized enterprise characteristic industry cluster.

Qian Ren, director of the Science and Technology Innovation Bureau of Changshu Economic Development Zone, said: "Under the background of high-quality development, more endogenous power of the economy will be stimulated, more innovation-driven implementation will be implemented, and the formation of industrial clusters with new productive forces in the field of acoustics will be promoted. We Our goal is to strive to achieve an acoustic output value of 70 billion yuan by 2025 and take the lead in forming an industrial innovation and technology research and development highland in the field of acoustics in the country."
