Description

Technical Field

[0001] The utility model relates to the technical field of speaker detection equipment, in particular to a detection device used for speaker production. Background Art

[0002] Speaker airtightness testing is a critical test to ensure the sealing performance of the speaker's internal components. Since there are usually high pressures and audio signals inside the speaker, if the seal is not good, it will cause air leakage, thus affecting the sound quality and even damaging the internal components.

[0003] The air tightness test of the speaker usually uses special testing equipment. These devices use negative pressure or pressure changes to detect the air tightness of the speaker. During the test, the speaker is connected to a closed test chamber, and then negative pressure is created or the pressure is changed. The pressure changes inside the test chamber are observed to determine whether the air tightness performance inside the speaker is good. For example, the Chinese utility model patent disclosed by publication number CN216349374U: Air tightness detection device for micro speakers for mobile phones, the turntable added in this application is equipped with multiple testing platforms. While testing the sealing of the mobile phone speaker, the mobile phone speaker to be tested can be placed, saving time and improving work efficiency. The added sealing device can improve the accuracy of the test data of the mobile phone speaker, but when testing the speaker, it is still necessary to manually pick up and place the speaker in the test table, and only one speaker can be tested at a time. After each test is completed, another pick-up and placement action is required, which makes the air tightness detection efficiency of the speaker low. Utility Model Content

The bottom plate 8 located at the rear side of the supporting plate 9 is provided with two through grooves 16. Two through grooves 16 are provided in the bottom plate 8, which can provide space for the vertical displacement of the two pushing triangles 15. The two mounting seats 12 are respectively provided with a first slide groove 17 on the opposite side, and a second slide groove 18 is provided on the top of the first slide groove 17. A side fixing block 19 is fixedly installed on the upper end of the mounting seat 12, and the side fixing block 19 is fixedly installed on one side of the mounting frame 3.

[0030] It should be noted that the present invention is a testing device for speaker production. When testing the speaker, the speaker can be placed on the rubber pad 10 and located in the sealed tube 21. Then, the remaining two speakers are placed on the other two rubber pads 10 in the same way. Then, the three cylinders 4 are synchronously started through the control box 2, so that the output end of the cylinder 4 can drive the slide 6 to slide up and down on the guide rail 5, and then the slide 6 drives the bottom of the pressure block 7 to cover the sealed tube 21.

When the speaker inspection is completed, the output end of the cylinder 4 drives the slide 6 to move up, and when the slide 6 moves up, it simultaneously drives the C-shaped connecting rod 25 to move up, so that the C-shaped connecting rod 25 is simultaneously moved through the two lifting rods 24 The two sliding blocks 22 are moved back and forth in the corresponding grooves 16, and the two sliding blocks 22 are moved back and forth in the corresponding grooves 16, so that the inclined surface at the upper end pushes the pushing plate 14 forward, thereby making the two sides of the pushing plate 14 slide in the corresponding first slide grooves 17 respectively, and the slider 22 slides in the corresponding second slide groove 18 and compresses the compression spring 23 in the direction of the limit block 13. Therefore, the pushing plate 14 drives the tested speaker forward through the sealed tube 21 and falls from the discharge port 26 into the discharge tray 27 for collection. Then, the output end of the cylinder 4 drives the slide 6 to move down and return to the initial position, which can make the C-shaped connecting rod 25 and the lifting rod 24 drive the pushing triangle plate 15 to move down synchronously, thereby making the two sliders 22 return to their original position with the help of the force of the compression spring 23 that rebounds by extension, which can make the two second slide grooves 18 drive the pushing plate 14 to return to their original position. Then, the untested speaker can be put back on the rubber pad 10.
