Description

TECHNICAL FIELD

[0001] The utility model relates to acoustical imaging technical field especially, and it is an acoustical imaging device. BACKGROUND

[0002] Acoustical imaging technology obtains multichannel sound wave (including ultrasonic wave) signal through microphone array collection, reconstructs and shows the spatial distribution of sound source in the form of image by using beam forming and other imaging algorithms, and can superimpose the image with the visible light image obtained by the camera to more intuitively show the sound source position, which can be used for detection and positioning of gas leakage, mechanical failure, partial discharge and other abnormalities.

[0003] The existing acoustical imaging device is mostly an integrated structure containing microphone array, camera, processor, memory, display screen, battery and other components, which is called handheld acoustical imager, and can independently realize signal collection, reconstruction processing and result display, but this also means that the overall size is limited by the size of the display screen, that is, it is difficult to improve portability without reducing the size of the display screen; and in order to send the imaging result to others or view it away from the imager, it is necessary to export it from the imager first, which is not convenient to use. In addition, there is a fixed acoustical imager on the market, which does not carry a display screen itself, but realizes user interaction by connecting a computer through a network cable. The fixed acoustical imager is mainly used for long-term monitoring at fixed positions, and although its size is not limited by the display screen and can be miniaturized, its combination with the computer is not suitable for handheld use. UTILITY MODEL CONTENT

[0004] In order to solve the technical problems of the existing acoustical imaging device that is not portable and not easy to use, the utility model provides an acoustical imaging device suitable for use with a mobile intelligent terminal.

[0005] The purpose of the present application is achieved by the following technical solutions.

[0006] The acoustical imaging device disclosed by the present application comprises a microphone array, a data acquisition and processing circuit and a connector.

[0007] The microphone array is connected with the data acquisition and processing circuit, the data acquisition and processing circuit is connected with the connector, and the connector is directly or through a data line connected with a mobile intelligent terminal.

[0008] The mobile intelligent terminal includes but is not limited to a smart phone and a tablet computer.

[0009] In some embodiments, the connector is a USB Type-C plug or socket.

[0010] In some embodiments, the acoustic imaging device and the mobile intelligent terminal are combined as a rigid whole after the connector is connected with the mobile intelligent terminal.

[0011] In some embodiments, the acoustic imaging device further comprises a clamp for fixing the mobile intelligent terminal, so that the acoustic imaging device and the mobile intelligent terminal are combined as a rigid whole.

[0012] In some embodiments, an external power supply interface is further included and connected with the data acquisition and processing circuit. When a matched power supply is inserted, the acoustic imaging device and the mobile intelligent terminal are powered by the power supply.

[0013] In some embodiments, a tripod connecting hole is further included, which is used for connecting a tripod or a monopod.

[0014] Advantages:

[0015] 1. Compared with the existing handheld acoustic imaging instrument, the acoustic imaging device of the present application is convenient to use with a mobile intelligent terminal, and the detection results can be displayed through the mobile intelligent terminal, so that the acoustic imaging device itself does not need to contain a display screen and other components, thereby further reducing the size, being more portable, and also reducing the cost. Users can flexibly select a mobile intelligent terminal with a different screen size to cooperate with the acoustic imaging instrument according to needs. The imaging results can be directly stored in the mobile intelligent terminal, and can be reviewed at any time and any place without being separated from the imaging instrument, and can be sent to others through various communication applications on the mobile intelligent terminal, so that the use is more convenient.

[0016] 2. Compared with the existing fixed acoustic imaging instrument, the acoustic imaging device of the present application is convenient to combine with a mobile intelligent terminal as a rigid whole, so that the user does not need to hold the mobile intelligent terminal and the acoustic imaging device separately when moving, and the use is more convenient. Since the acoustic imaging device, which is the source of the original data of the acoustic imaging results, and the mobile intelligent terminal, which is used to display the acoustic imaging results, are combined as a rigid whole, the movement of the display screen is synchronized with the movement of the picture in the display screen when the user holds and moves, which is more intuitive.

[0022] [Example 1]

[0023] An acoustic imaging device, as shown in Figure 1 , Figure 2 , comprises a microphone array 1, a data acquisition processing circuit 2, a connector 3 and a camera 4.

[0024] The data acquisition processing circuit 2 acquires microphone sound wave data through the microphone array 1 and visible light image data through the camera 4, processes the microphone sound wave data and the visible light image data, and transmits them to a mobile intelligent terminal through the connector 3. The mobile intelligent terminal includes but is not limited to a smartphone and a tablet computer.

[0025] In this embodiment, the connector 3 is a USB Type-C plug. After it is inserted into the USB Type-C socket of the mobile intelligent terminal, in addition to the above data transmission, the mobile intelligent terminal can also supply power to the acoustic imaging device through the connector 3. The mobile intelligent terminal and the acoustic imaging device are combined into a rigid whole. When a user uses it, he can hold the mobile intelligent terminal or use a selfie stick, a mobile phone support or other devices on the market to clamp the mobile intelligent terminal, without the need to hold the acoustic imaging device additionally.

[0026] Furthermore, a telescopic or rotating mechanism can also be provided between the connector 3 and other parts of the acoustic imaging device, so as to store the connector in the shell when not in use to avoid damage.

[0029] The data acquisition and processing circuit acquires sound wave data of each microphone through the microphone array 1 and visible light image data through the camera 4, processes the sound wave data and the visible light image data, and transmits the processed data to the mobile intelligent terminal 9 through the connector 3 and the connecting line 8.

[0030] The clamps (including the fixed clamp 501 and the movable clamp 502) are used to fix the mobile intelligent terminal 9, and combine the acoustic imaging device and the mobile intelligent terminal into a rigid whole.

[0031] The tripod connecting hole 6 can be used to connect a tripod, a monopod, etc.
