Mounting apparatus for microphone array for use in multi-frequency-band sound source localization

Abstract

A mounting apparatus for a microphone array for use in multi-frequency-band sound source localization, comprising a central array disk (1), wherein the central array disk comprises a support ring (101) and a support disk (102) arranged at the center; the support ring and the support disk are connected by means of a plurality of array support arms (103) that are spirally distributed; the array support arms are centrally symmetric; the outer side of the support ring of the central array disk is detachably connected to one end of each of array main support arms (2); the array main support arms have one-to-one correspondence to the array support arms; the other end of each array main support arm is detachably connected to a corresponding array secondary support arm (3). In the mounting apparatus for the microphone array for use in multi-frequency-band sound source localization, the aperture of the microphone array can be adjusted, and the aperture of the microphone array can be changed with the change of a sound source localization frequency; arrays having multiple array apertures can be obtained by means of assembly and disassembly of the array main support arms and the array secondary support arms, thereby stepwise increasing the aperture of the microphone array, and stepwise enlarging a localization frequency band.
