Description

Technical Field

[0001] This utility model relates to the field of imaging detection technology, and in particular to a handheld acoustic imaging instrument. Background Technology

[0002] Acoustic imaging technology is a sound source localization and imaging technique based on microphone arrays. It determines the sound source location by measuring the phase difference of sound waves reaching different microphones in space, using the principle of phased arrays, and displays the spatial distribution of the sound source as an image, forming an acoustic image. Acoustic images typically use color and brightness to represent the intensity of the sound source and are widely used in industrial inspection, environmental noise monitoring, fault diagnosis, and other fields.

[0003] Since existing acoustic imaging equipment often lacks powerful built-in data processing capabilities or high-definition display screens, after completing acoustic signal acquisition, a large amount of raw data needs to be transmitted to a desktop or laptop computer via a wired connection, and then rely on dedicated software on the host computer to perform complex algorithm calculations and image generation.

[0004] However, this traditional structure not only makes the operation process cumbersome and heavily relies on external computing equipment, preventing users from obtaining real-time acoustic imaging results on-site, but also greatly reduces the overall efficiency of the detection work, prolongs the cycle from data acquisition to analysis, and makes it difficult for users to make quick judgments and decisions during the detection process. If technicians discover a suspicious sound source on-site but cannot immediately confirm and analyze its specific characteristics, and must return to the office environment to process the data, this not only increases the possibility of repetitive work, but also loses the immediacy and specificity of on-site diagnosis, ultimately affecting the effectiveness of troubleshooting and equipment status assessment.

[0019] like Figures 1 to 4 As shown, this utility model claims protection for a handheld acoustic imaging instrument, including a mounting shell, an acoustic module 5, a high-definition module 6, a circuit board 7, a battery 8, etc.; wherein, the mounting shell includes a first shell 1 and a second shell 2, the first shell 1 is connected to the rear shell 3 of the acoustic module, the rear shell 3 of the acoustic module and the front shell 4 of the acoustic module enclose to form a cavity, and each major component is installed in the cavity.

[0020] Specifically, within the chamber, from the front shell 4 to the rear shell 3 of the acoustic module, an acoustic module 5, a high-definition module 6, and a circuit board 7 are arranged sequentially. The acoustic module 5, used for acquiring acoustic signals, is mounted and fixed on an isolation bracket 10. The isolation bracket 10 serves to secure the acoustic module 5, ensuring its stability within the instrument. Sound-absorbing cotton 11 is provided between the acoustic module 5 and the front shell 4. This cotton helps reduce external noise interference with acoustic signal acquisition, improving the accuracy of the acquisition. Figure 1 as well as Figure 2It can be seen that through holes are respectively opened on the front shell 4 of the acoustic module and the sound insulation cotton 11. These through holes help the acoustic module 5 to collect signals and ensure that the acoustic signal can smoothly enter the acoustic module 5.

[0021] The high-definition module 6, used for acquiring image signals, is also fixedly mounted on the isolation bracket 10 and is located adjacent to the acoustic module 5 within the cavity. Its signal acquisition is also achieved through corresponding through holes on the front shell 4 of the acoustic module and the sound insulation cotton 11 to ensure smooth image signal acquisition. The circuit board 7 is electrically connected to both the acoustic module 5 and the high-definition module 6, and is used for preprocessing and transmitting the acquired acoustic and image signals.

[0022] In this embodiment, the circuit board 7 is connected to a second TYPE-C interface 12. The acoustic module rear shell 3 has an opening 301 corresponding to the second TYPE-C interface 12, and a detachable TYPE-C silicone plug 13 is provided at the opening 301. The second TYPE-C interface 12 is used for possible direct connection of external devices to the circuit board 7 or for data transmission expansion, etc. Under normal circumstances, it is protected by the TYPE-C silicone plug 13 to prevent dust and other contaminants from entering and affecting the internal circuitry.

[0023] The battery 8 is located inside the first housing 1 and supplies power to the acoustic module 5, the high-definition module 6 and the circuit board 7.

[0024] The second housing 2 is provided with a first TYPE-C interface 9, which is electrically connected to the circuit board 7. The mobile terminal is inserted into and connected to the first TYPE-C interface 9 along the slot 201 formed in the second housing 2, thereby establishing a communication connection with the circuit board 7. In this way, the handheld acoustic imaging instrument can interact with the mobile terminal, such as transmitting the collected signals to the mobile terminal for further processing or analysis. In this embodiment, the mobile terminal is a mobile phone.

[0025] The second housing 2 is provided with a mobile phone fixing structure 16, which includes at least one mobile phone fixing screw.

The infrared sensor is electrically connected to the circuit board 7 to collect temperature data and transmit it to a mobile terminal. In some application scenarios, temperature data may be helpful for acoustic imaging or other related analyses. By collecting temperature data with the infrared sensor and transmitting it to the mobile terminal, users can gain a more comprehensive understanding of the detection environment.

[0029] One end of the first housing 1 protrudes outward to form a handhold 101, and the surface of the handhold 101 is provided with anti-slip friction texture. The anti-slip friction texture design can increase the friction when the user holds the instrument, improve the stability of the grip, make it easier and safer for the operator to use the instrument, and reduce the risk of the instrument being dropped and damaged due to hand slippage.
