Title:
OMNIDIRECTIONAL ACOUSTIC CAMERA USING MEMS ACOUSTIC SENSOR AND OMNIDIRECTIONAL SOUND VISUALIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104972
Kind Code:
A1
Abstract:
Disclosed is an omnidirectional acoustic camera using a MEMS acoustic sensor, the omnidirectional acoustic camera being characterized by comprising: a sphericity body (10) having a hollow portion formed therein; MEMS sound sensing sensors (20) arranged on the surface of the sphericity body (10) to be exposed and spaced from each other; an acoustic signal acquiring board (30) electrically connected to each of the MEMS sound sensing sensors (20) and contained in the hollow portion of the sphericity body (10); an omnidirectionally reflective mirror (40) fixed to be spaced from the upper portion of one side of the sphericity body (10); and an imaging lens (50) fixed to the upper portion of one side of the sphericity body (10) to be exposed upwards, thereby taking an optical image reflected in the reflective mirror (40).
