Great Britain flies and insults and introduces and adopts MEMS craft and miniature silicone base microphone suitable for the all automatic production flow of consumption electronic product At international electronic devices and components and assembly trade fair of 2006 Munich, Great Britain flies and insults the scientific and technological joint-stock company (FSE/NYSE: IFX) Exhibition was suitable for communicating device and computer communication apparatus of ordinary consumption " Miniature " Silicone base microphone. This new microphone is probably only as big as half of the ordinary microphones, but its power consumption is only 1/3 of the ordinary microphone. The new Mike's elegance uses silicone base MEMS ' Miniature electromechanical system) The craft, have acoustics and electricity characteristic the same as ordinary microphone, but stronger and durabler, the heat-resisting characteristic is stronger. The new microphone has offered greater flexibility for numerous product designs, at the same time for integrating opening up a new route of the microphone. New silicone base MEMS microphone is strengthened even more than the ordinary microphone that use at present toughly, the heat-resisting characteristic is stronger. The ordinary microphone usually uses electret microphone (ECM) Technology. The heat-resistance temperature of silicone base MEMS microphone developed flies and insults and is up to 260 ℃, has very strong antivibration characteristics from Great Britain. Because the products have higher heat-resistance temperatures, the new microphone can be welded on any standard PCB easily, especially suitable for producing the whole automatic production line of the popular consumption electronic product. The mains voltage of the new microphone is only 1.5 to 3.3V, drop the power consumption of the products to 1/3 (70μ A) of ECM microphone Left and right sides. Include two chips in the new microphone: MEMS chip and application-specific integrated circuit (ASIC) Chip. Two chips are capsulated in a surface mounted device. MEMS chip includes a rigid drilling rear electrode and a sheet of elasticity silicon film which is used as the capacitor. This elastic silicon film changes sound pressure into the electric capacity change. ASIC chip is used for detecting the change of electric capacity, and change it into electric signal, transmit to relevantly and deal with the device, such as base band processor or amplifier,etc.. Silicone base MEMS microphone has wide use range, can already be used in new mobile phone and mobile phone model, it also can be used for the consumption electronic product, notebook computer and medical equipment ' Such as acouophone) ,It can apply to the car trade ' Such as device for speaking through of the hand-free) . Great Britain flies and insults scientific and technological car, industry and part on the electronic market of pluralism of joint-stock company to set up the banking department of the device and is in charge of Peter Schiefer to think, "such new microphone will be applied to the industrial field, the wave sensor such as using uttering a word, the monitoring aid operates. " It is unique on the market that silicone base MEMS microphone flies and insults from Great Britain. Because Great Britain fly to, it insults companies to be whether only can melt on the same capsulation, possess relevant supplier of operational capacities at the same time MEMS and the intersection of ASIC and technology. The manufacture process of MEMS microphone, the development of branch company flies and is insulted in Great Britain which Leavey draws hertz from lying in. Company Wicht scientific and technological advisory company (WTC) of the market research It is estimated, the sales amount of the market of silicone base microphone will rise to 680 million dollars in 2010 from 56 million dollars in 2005. Schiefer is consequential to this investigation Comments on showing: "Silicone base microphone products will stand firm on the market quickly, Great Britain has sufficient operational capacities to guarantee the source of goods to insult to fly at the same time. Our goal is to become the world-leading silicone base microphone supplier. " New appearance of microphone, MEMS of silicone base, strengthen Great Britain fly to, insult the intersection of company and Off-The-Shelf machinery and battle array of product, MEMS of radio frequency. Company's Off-The-Shelf product mix includes the accelerometer, gyroscope and bulk acoustic wave (BAW) Electric-wave filter. Techincal characteristics of the new MEMS microphone It has very good acoustics characteristics that the key feature of insulting silicone base MEMS microphone of the company flies from Great Britain, such as higher signal to noise ratio ' 59dB( A) )And better sensitivity ' 10mV/Pa) . Because of having these advantages, MEMS microphone replace electret microphone in the future. The characteristic of silicone base MEMS microphone at different temperatures is very stable at the same time. But the speech of comparing the bigger microphone, the pocket flat pack of the new MEMS microphone (4.72 mm
