Horn waterproof rainfall test cover

Abstract

A horn waterproof rainfall test cover disclosed by the present invention comprises a frame, kidney shape holes, a side plate, a middle plate, a transparent plate, a pressure bars, a horn pedestal, bayonets and side ports. The frame is a rectangular frame, and the side plate is arranged at the inner side of the frame. Three surfaces of the side plate are inclined plates, and one surface is vertical with the frame. The end face of the side plate is equipped with the folded edges, the transparent plate is assembled at the folded edges via the sealing glue cushions, the pressure bars and the fixing screws, and the frame, the side plate and the transparent plate form the test cover. The middle plate is welded and fixed at the middle position of the test cover, the horn pedestal is arranged at the middle position of the transparent plate and is rotatably sealed and assembled on the transparent plate, and an inner ring of the horn pedestal is equipped with the bayonets and the side ports. According to the present invention, by an inwards recessed cover body, the horn is placed at a test position, and the rotary horn pedestal adjusts the rotation orientation of the tested horn, so that the waterproof rainfall performances in various directions of the horn are tested, and the horn waterproof rainfall test cover is good in detection effect and high in detection efficiency.

Description

technical field [0001] The invention relates to the field of horn detection technical equipment, in particular to a horn waterproof and rain test cover. Background technique [0002] The application of speakers or speakers in TVs, computers, mobile phones and various electrical appliances is becoming more and more common. The requirements for the waterproof performance of speakers are increasing, especially as speakers that emit sound, they need to have a waterproof effect, so as to avoid the passage of water in the external environment. The speaker enters the rear cavity, and then enters the interior of the appliance, resulting in damage to the function and performance of the appliance. [0003] In the prior art, the waterproof performance of the loudspeaker or the horn is usually detected by a rain tester, and whether it meets the standard requirements is determined according to the test result of the waterproof performance and the waterproof rain test result of the horn, ...

AI Technical Summary

Problems solved by technology

[0002] Speakers or speakers are more and more widely used in TVs, computers, mobile phones and various electrical appliances. The waterproof performance of speakers is required to be improved, especially as speakers that produce sound, they need to have waterproof effects, so as to prevent water from the external environment from passing through. The speaker enters the rear cavity and then enters the interior of the electrical appliance, resulting in functional damage and performance degradation of the electrical appliance

[0003] In the prior art, a rain tester is usually used to test the waterproof performance of speakers or horns. Based on the test results of the waterproof performance and the results of the waterproof rain test of the speakers, it is judged whether they meet the standard requirements. However, the defects of the prior art are: In the rain test machine, the fixed test device installed on the speaker is not suitable for the waterproof performance test of the speaker, so that the test environment and conditions cannot meet the requirements of the actual environment waterproof, the test effect is not ideal, and the test efficiency is low
