MEMS Acoustic Scanner With MEMS Microphone Array

摘要

The present invention relates to an acoustic scanner using a MEMS microphone array, and more specifically, a bellows (10) capable of maintaining shape when the external force does not change shape and external force, and the MEMS microphone (20) is a printed circuit board ( A plurality of sound channels 50 mounted on the bellows 10 and spaced apart from each other in the middle of the bellows 10, connecting the sound channels 50, and transmitting a sound signal measured by the MEMS microphone 20. A data array cable (70) and a microphone array (100) having; Data acquisition and transmission that are electrically coupled to one end of the data transmission cable 70 to collect sound signals transmitted by the data transmission cable 70 and transmit them to the data handling unit 300. A board 200; Data handling unit for storing the sound signal transmitted from the Data Acqusition and Transmission board 200 for each channel (Ch), and reproduces the sound signal measured by the listening means (not shown) for each channel It relates to an acoustic scanner using a MEMS microphone array, characterized in that configured to include (300).
