Designed for notebooks, AAC launches its first ultra-narrow edge 67dB digital microphone

CTOnews.com, November 19, according to the official news of AAC AAC Technology, AAC Technology recently developed the first ultra-narrow edge 67dB SNR (signal-to-noise ratio) digital microphone, which is equipped with a full self-developed chip. From design, R & D to production, the whole process of localization has been realized.

According to reports, compared with the microphone used by mainstream Windows notebook computers on the market, this product has smaller size, higher signal-to-noise ratio and wider range of broadband response. It can not only better adapt to the comprehensive screen design of notebook computers, but also increase its far-field sound pick-up distance exponentially. Voice signals can still be clearly picked up 4 meters away, which can greatly improve the audio performance of notebook computers.

CTOnews.com learned that the new product is equipped with AAC 1 x 1mm small-size high-performance microphone chip, using self-developed single backplane MEMS technology, with MEMS design, the sensitivity is-26dBFS, the signal-to-noise ratio (SNR) is 67dB, and the sound saturation point (AOP) is 120dBSPL in the ultra-narrow side package of 4 x 2 x 1.1mm ³. Officials say the product achieves the ultra-narrow edge size of the 2mm and is suitable for camera modules, with sound holes on top of the microphone to meet the design needs of today's large-screen laptops.
