Acoustic imaging detector

Abstract

The invention discloses an acoustic imaging detector, and relates to the field of acoustic imaging applications. The acoustic imaging detector comprises a detector body, wherein a first microphone matrix used for receiving vibration sound waves is arranged in the detector body, at least one extension rod is detachably arranged on each of the two sides of the detector body, each extension rod is provided with at least one microphone in communication connection with the detector body, and the first microphone matrix and all microphones arranged on the extension rod jointly form a second microphone matrix used for receiving vibration sound waves. According to the invention, a detachable extension rod mode is creatively adopted, the left side and the right side of the detector body are additionally provided with a plurality of microphones, and the additionally arranged microphones are combined with the first microphone matrix of the detector body to form a second microphone matrix which iswide in distribution and can receive lower-frequency vibration sound waves compared with the first microphones, so that the receiving frequency band range of the whole detector is widened on the premise that the portability of the whole detector is guaranteed; and the extension rod has the advantages of simplicity in assembly and disassembly, convenience in carrying and the like.

Description

technical field [0001] The invention relates to the application field of acoustic imaging, in particular to an acoustic imaging detector. Background technique [0002] It is very difficult to accurately locate the noise source by naked eyes and ears alone, and an acoustic imaging detector is required for detection. The acoustic imaging system is a new type of noise source identification, location and test analysis system. It uses a high-sensitivity digital microphone to visualize the collected sound on the screen in the form of a color contour map, effectively measuring the sound field distribution, and the sound image map. It is perfectly superimposed with the video image of visible light to form a detection effect similar to that of a thermal imager on the temperature of an object. It can quickly identify and locate steady-state, transient and moving sound sources, helping people to intuitively identify sound waves, sound fields and sound sources, and understand The locat...
