Market Overview and Growth Potential - Global MEMS sensor market in 2021 was approximately 30billion,withtheChinesemarketat45billionRMB,showingacompoundannualgrowthrate(CAGR)of1330 billion, with the Chinese market at 45 billion RMB, showing a compound annual growth rate (CAGR) of 13% [4] - MEMS speakers are expected to rapidly replace traditional speakers, similar to how silicon microphones replaced traditional microphones in just 3 years [7] - MEMS speakers have significant advantages in TWS earphones, hearing aids, AR/VR glasses, and smart home devices due to their small size and low power consumption [7][10] Technological Advancements and Innovations - MEMS (Micro-Electro-Mechanical Systems) integrate micro-mechanical structures, sensors, actuators, and communication into a single system, offering small size, lightweight, and low power consumption [4] - The National Intelligent Sensor Innovation Center has developed a 12-inch sensor pilot line, with 80% of the equipment being domestically produced, achieving world-leading process levels [4] - MEMS speakers use piezoelectric materials, with PZT (lead zirconate titanate) being a key material. The center has developed a unique PZT wafer and a MEMS process platform compatible with CMOS, enabling multi-layer film stacking and high-performance film preparation [6][9] Applications and Market Opportunities - MEMS speakers are particularly advantageous in TWS earphones, where they can replace traditional planar drivers and balanced armature units, offering better performance in high-frequency ranges [10] - In AR/VR glasses, MEMS speakers provide directional sound, enhancing the immersive experience. They can also be used in smart home devices like TVs and smart speakers [9][10] - MEMS speakers are expected to enter the smartphone market, with potential applications in replacing traditional speakers for improved sound quality and cost efficiency [11] Production and Cost Considerations - The current production capacity is 10,000 wafers per year, with each wafer yielding approximately 8,000 MEMS speakers. The yield rate is 98%, and production can be scaled up based on market demand [11] - The initial cost of MEMS speakers is higher than traditional speakers, with a target price of 2 per unit. However, costs are expected to decrease as production scales up and technology matures [8][11] - MEMS speakers require specialized ASIC (Application-Specific Integrated Circuit) development for driving piezoelectric elements, which is currently in progress [11][12] Future Outlook and Challenges - MEMS speakers are expected to achieve mass production by the second half of 2023, with a projected market price of 4-5 RMB per unit [12] - The main challenges include optimizing the production process, reducing costs, and developing compatible ASIC chips for different applications [11][12] - The MEMS speaker market is expected to grow rapidly, with potential applications in various industries, including consumer electronics, automotive, and healthcare [9][10][11]
