Description

Technical Field

[0001] This utility model belongs to the field of equipment testing technology, specifically relating to a microphone temperature and humidity environment performance testing device. Background Technology

[0002] In the field of audio equipment, microphones, as an important sound acquisition device, are widely used in various scenarios such as performances, conferences, recording, and live streaming. Different usage scenarios place diverse demands on microphone performance, among which the influence of temperature and humidity on microphone performance is a crucial factor that cannot be ignored.

[0003] In high-humidity environments, the electronic components inside a microphone are susceptible to moisture, which can lead to short circuits, oxidation, and other problems, affecting its electrical performance and causing signal distortion, increased noise, and other malfunctions. For example, in a damp outdoor performance venue, if the microphone does not have good moisture resistance, it may experience sound abnormalities within a short period of time, severely impacting the performance. To ensure that microphones can work stably and reliably under various temperature and humidity conditions, rigorous temperature and humidity performance testing is required during the microphone's production and R&D process. However, there is currently a lack of equipment specifically designed for testing the temperature and humidity performance of microphones on the market. Existing testing methods mostly use simple devices, placing the microphone in a common sealed container and testing by artificially adding moisture or changing the ambient temperature. This method has many drawbacks. On the one hand, it is impossible to accurately control the temperature and humidity inside the sealed container, making it difficult to simulate a real and complex temperature and humidity environment, resulting in inaccurate test results that do not truly reflect the microphone's performance in actual use. On the other hand, the lack of effective monitoring methods during the testing process makes it impossible to obtain real-time temperature and humidity data at different locations around the microphone, making it difficult to comprehensively assess the impact of temperature and humidity on microphone performance and reducing the accuracy of the test. Therefore, this application proposes a microphone temperature and humidity performance testing device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This embodiment provides a microphone temperature and humidity environment performance testing device, the structural schematic diagram of which is shown below. Figures 1-4 As shown, it includes a box body 1 and a shell 2.

[0026] In this embodiment, the box body 1 is rectangular in shape, and the cover 2 is placed on the box body 1, forming a sealed test space between the box body 1 and the interior of the cover 2. A boss 10 and a sealing gasket 11 are provided at the top of the inner wall of the box body 1, with the sealing gasket 11 located above the boss 10. When the bottom end of the cover 2 is inserted into the box body 1, the bottom end of the cover 2 abuts against the boss 10, while the sealing gasket 11 provides a good seal, ensuring the airtightness between the cover 2 and the inner wall of the box body 1, preventing outside air from entering and affecting the test results. The top end of the cover 2 is designed as a rounded surface, which not only increases the overall aesthetics but also reduces the accumulation of dust and other impurities to a certain extent. A handle 3 is provided on the side wall of the cover 2 for easy opening and closing by the operator.

[0027] Furthermore, a perforated plate 6 is provided at the top inside the box body 1. The perforated plate 6 includes a frame 12 fixed to the top inside the box body 1. A support plate 13 is horizontally fixed in the middle of the frame 12. A mesh 14 is provided between the support plate 13 and the inner wall of the frame 12. The mesh 14 can play a certain role in isolation, while not affecting the air circulation and water droplet recycling.

[0028] Furthermore, the perforated plate 6 is equipped with multiple microphone holders 7 and multiple temperature and humidity sensors 8, which are spaced apart from the microphone holders 7 to more comprehensively detect the temperature and humidity conditions at different locations around the microphone. Specifically, the microphone holder 7 includes a vertical arm 15 fixed to the support plate 13 and a collar 16 fixed vertically to one side of the top of the vertical arm 15. The bottom end of the vertical arm 15 is bent horizontally and fixedly connected to the support plate 13. A triangular reinforcing plate 18 is fixed between the horizontal part of the bottom end of the vertical arm 15 and the side wall of the vertical arm 15. The reinforcing plate 18 enhances the connection stability between the vertical arm 15 and the support plate 13, preventing the microphone holder 7 from shaking when placing the microphone. The diameter of the collar 16 gradually decreases from top to bottom, forming a structure that is wider at the top and narrower at the bottom, which facilitates the insertion of the microphone. The collar 16 also has a notch 19 on one side for easy removal and placement of the microphone. A rubber pad 17 is provided on the inner wall of the collar 16. The rubber pad 17 can protect the microphone and prevent the microphone from directly contacting the inner wall of the collar 16 and causing scratches. At the same time, it can also increase the friction between the microphone and the collar 16, making the microphone more stable.

[0029] Furthermore, humidifiers 9 are provided at the four corners of the top of the perforated plate 6. Specifically, the humidifiers 9 are installed at the four corners of the frame 12 to humidify the sealed space formed between the shell 2 and the inside of the box 1, so as to meet the testing requirements under different humidity environments.

[0030] In a preferred embodiment, a drain pipe 4 and a controller 5 are provided on the side wall of the housing 1. The drain pipe 4 is located at the bottom of the side wall of the housing 1 and communicates with the internal space of the housing 1. When condensate or other liquids are generated during the test, they can be discharged through the drain pipe 4. The controller 5 is connected to the temperature and humidity sensor 8 and the humidifier 9. The temperature and humidity sensor 8 transmits the detected temperature and humidity data in the sealed space to the controller 5 in real time. The controller 5 controls the humidifier 9 according to the preset test parameters to adjust the humidity in the sealed space, thereby achieving accurate testing of the microphone's temperature and humidity performance.

[0031] Working principle:

[0032] When using this microphone temperature and humidity environment performance testing equipment, the operator first opens the shell 2 through the handle 3, inserts the microphone to be tested into the collar 16 of each microphone bracket 7, and then closes the shell 2 so that the bottom of the shell 2 is embedded into the box 1 and abuts against the boss 10. The sealing gasket 11 ensures the sealing between the shell 2 and the box 1, forming a closed test space.

[0033] The required humidity parameters are set via controller 5. Temperature and humidity sensors 8 monitor the temperature and humidity data in the sealed space in real time and transmit the data to controller 5. When the detected humidity is lower than the preset value, controller 5 activates humidifier 9, which sprays mist into the sealed space to increase the humidity. As the humidification process continues, temperature and humidity sensors 8 continuously monitor humidity changes. When the humidity reaches the preset value, controller 5 stops humidifier 9. Throughout the test, multiple temperature and humidity sensors 8 are spaced around microphone holder 7, enabling comprehensive and accurate monitoring of the temperature and humidity of the microphone's environment. After the test, the operator opens the housing 2 again via handle 3 to remove the microphone. If condensation or other liquids are generated during the test, they can be drained through drain pipe 4.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
