Across multiple electronic applications, the world's leading semiconductor supplier STMicroelectronics (STMicroelectronics, referred to as ST) and audio Usound fast-growing innovative companies jointly announced the promotion of cooperation and manufactures the world's first intelligent audio system for portable devices miniature piezoelectric MEMS (Micro Electro Mechanical Systems) actuators.
The patented Usound Microspeaker technology is designed to replace the most commonly used balance armature speakers and mobile phone handsets. These actuators use ST 's market-leading thin film piezoelectric (TFP) manufacturing technology to increase the scalability and cost-effectiveness of smart ear-worn terminals and handsets while ensuring lower power consumption and heat consumption. Scattered, and will not affect the sound quality.
Vice president and chief STMicroelectronics MEMS microactuators, General Manager of the actuator AntonHofmeister expressed: "Usound technology and piezoelectric MEMS actuator will let portable device reliability semiconductors, manufacturing efficiency, and of course on consumption The most important - better sound quality. STMicroelectronics is the world's largest consumer electronics and mobile device sensor manufacturer, this cooperation allows us to take another step in expanding the MEMS product portfolio, using our high-value actuation technology Entering a large market with a high technical threshold."
Usound CEO Ferruccio Bottoni said: "Semiconductor technology and MEMS R & D capabilities of STMicroelectronics is the ideal partner to bring this unprecedented speaker technology to the market. Compared with standard speakers, piezoelectric MEMS speakers are slim The mechanical precision has reached an unprecedented level, which improves the sound reproduction fidelity and equipment reliability. As the first product of its kind, our MEMS “Moon†speaker is aimed at the earphone application, bringing a cost-effective intelligent ear to the audio market. Wear the terminal."
The two companies expect piezoelectric MEMS actuators to be commissioned in the third quarter of this year, and consumer electronics products using this product will be available at the end of the year.
1. Decomposition: biodegradable excess body fat, flat meat, all kinds of stone decomposition, promote the decomposition of food digestion and absorption.
2. Blood purification: Arrange internal environment, purify the blood and improve physical fitness - decomposition, eliminate waste, the blood becomes acid.
3. activation: the pituitary gland to stimulate cell regeneration, a recession is not easy to remember, can not afford to skin wrinkles, youthful beauty delay human aging.
4. Anti-inflammatory antibacterial effect: enzymes can strengthen the fight against white blood cells and remove invading bacteria and purulent matter, the cells speed recovery and enhance wound healing
5. hangover, hangover prevention.
6. For picky eaters, do not like to eat fruits and vegetables children the best nutritional supplements and energy sources.
It contains nutrients more easily absorbed by the body, containing amino acids, polysaccharides, protein components, vitamins B, C, E, and trace elements needed by the body. Long-term use, long-term preservation.
