An acoustic imager is a device that visualizes sound, and is generally used for localization of device failure sounds. The microphone array technology can be combined with the camera, and the handheld integrated equipment for displaying the distribution state of the sound source in space in real time in an image mode helps a user to position the abnormal sound position, so that the problem of limited hearing of human ears is solved.

As shown in fig. 1 and 2, the present invention provides an acoustic imager including an apparatus main body 10, a microphone 20, and an adjustment member 30.

The device body 10 may be composed of a casing and internal electronic components, and the casing may protect the internal electronic components.

The processor 50 is installed in the device main body 10, the processor 50 may have a logic operation function, the processor 50 may be a central processing unit 50CPU, an industrial personal computer, a single chip microcomputer, or the like, and any electronic component capable of performing logic operation of an electrical signal may be the processor 50, and the type and specific model of the processor 50 are not particularly limited herein.

The microphone 20 is electrically connected to the processor 50, and the microphone 20 can collect a sound signal in a certain direction and send the sound signal to the processor 50 for processing.

The processor 50 can obtain audio data after the sound signal, obtain an acoustic imaging result according to the audio data, and conveniently find out a fault point and a fault reason of the equipment according to the acoustic imaging result.

The number of the microphones 20 may be two or more, each of the microphones 20 collects sound signals in a specific direction, sound signals in different directions have a certain difference, and sound signals can be located according to the difference between the sound signals collected by the plurality of microphones 20.

The microphone 20 is attached to the adjuster 30, and the adjuster 30 is connected to the apparatus body 10 in a turnable manner.

The microphone 20 may be mounted on a side of the adjustment member 30 facing away from the apparatus body 10, and the pickup end of the microphone 20 may always face outward, so that the sound signal is prevented from being blocked by the adjustment member 30 and the apparatus body 10.

The adjustment member 30 may be in the form of a sheet and may be quadrilateral in shape. The size of the adjusting member 30 can be 20cm by 20cm, the adjusting member 30 can be connected with the device main body 10 in a turnover mode, and since the microphone 20 is installed on the adjusting member 30, the orientation of the collecting end of the microphone 20 can be changed by turning the adjusting member 30 relative to the device main body 10, so that the sound collecting direction can be adjusted, and the sound collecting requirements in different directions can be met.

The shape of the adjustment member 30 may be a sector, for example, a portion of a complete circle may be cut out, and the shortest curved portion of the adjustment member 30 may be connected to the apparatus body 10 in a reversible manner.

Of course, the adjustment member 30 can have other shapes, such as triangular, diamond, or oval.

When the user holds the device main body 10, when measuring the sound source of the device in different directions, the user can turn over the adjusting member 30 to adjust the orientation of the microphone 20 without changing the direction of the device main body 10, and the user can easily turn over the adjusting member 30 without changing the holding posture of the device main body 10.

It is worth mentioning that, in the existing acoustic imager, when a user wants to change the collection direction of the sound signal, the holding posture of the acoustic imager needs to be changed, and some holding postures are easy to fatigue for a human body, which causes inconvenience for the user to use, so that the working efficiency is low.

In practical application, the mass of the existing acoustic imager is usually 2kg to 3kg, and it is hard for a general user to hold the acoustic imager for a long time, but the acoustic imager is often used for detecting equipment failure conditions at a high place, such as for detecting a high-voltage overhead line or an overhead gas pipeline, when detecting a sound source at the high place, the existing acoustic imager needs to be integrally directed to the sound source at the high place, so that a maintainer needs to lift the whole acoustic imager, even hold over the head, so that the hands of the user bear a large weight, when the acoustic imager is used for long-time detection, hands fatigue may be caused, in addition, when the detection process is in a strong outdoor sunlight condition, if the acoustic imager is integrally directed to the high place, the display screen 60 of the acoustic imager is also located at the high place, and in the absence of shielding objects, the reflection of light easily appears, influences the observation sight.

In contrast, in the acoustic imager of the present embodiment, when detecting an equipment failure condition at a high location, the holding posture of the equipment main body 10 does not need to be changed, and only the adjusting member 30 needs to be turned over, and the pitch angle of the adjusting member 30 is changed, so that the orientation of the collecting end of the microphone 20 can be conveniently adjusted, and the equipment failure condition at the high location can be quickly and easily detected without changing the holding posture of the equipment main body 10.
