STMicroelectronics further expands the product portfolio and launches the low-power digital MEMS microphone of new high-performance. MP34DT01 pickup holes overhead microphone from STMicroelectronics uses 3x4x1mm ultra-small packages, so that cell phones, tablet PCs and other consumer electronic devices could bring consumers the best listening experience in the same class products .MP34DT01 uses innovative technology, designers can place the microphone diaphragm in the top of the package away from the microphone hole, thus improving microphone performance, without increasing the footprint size, the technology of patent applications are pending. As the first pickup holes overhead digital MEMS microphone, MP34DT01 is far better than other competing products, acoustic parameters are better than the existing hole under the rear microphone pickup, fully meet the requirements of new consumer electronics devices supporting voice control software and electronics applications software.MEMS microphone uses the best acoustic sensor technology developed with Omron, the technology is less susceptible to mechanical vibration, temperature changes and electromagnetic interference, which could restore high-fidelity audio signal level, and low power consumption.MP34DT01 is STMicroelectronics's second high-end MEMS microphone. STMicroelectronics plans re-introduction of new products in 2012 and 2013, new generation of products will have a better signal to noise ratio, the sensitivity is less than 1dB consistency, and further reduce the size.
