[0001] The utility model relates to the technical field of headphone product testing, and specifically relates to a MIC hole-blocking mechanism for testing electroacoustic products. Background Technique

[0002] When noise-canceling headphone products are produced, it is usually necessary to test their various performance indicators, such as left and right channel tests, MIC (microphone) and button tests, etc. Among them, when testing the MIC (microphone), a MIC hole-blocking mechanism is required. The MIC hole-blocking mechanism mainly forms a closed space for the headphone to block external noise, thereby completing the test of the noise-canceling performance index.

[0003] At present, the design of the existing MIC hole-blocking mechanism is either relatively complex, with a large acoustic reflection surface and high cost; or too simple, with poor MIC sealing effect and unable to perform automated testing, and manual testing needs to be changed to accurately adjust to the required test requirements, so it is more inconvenient to use. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: a MIC hole-blocking mechanism for testing electroacoustic products, including a fixing plate, on the surface of which an EVA sponge is adhesively fixed, and this EVA sponge is used to weaken the interference generated by the movement collision of the entire mechanism; at both ends of the top of the fixing plate, a pneumatic module is installed, and this pneumatic module is composed of a mounting frame, a transverse movement cylinder and a transverse movement plate. There are two groups of mounting frames, and the two groups of mounting frames respectively penetrate through the EVA sponge and are fixedly connected to both ends of the fixing plate. A transverse movement cylinder is fixed on the surface of the mounting frame, and a transverse movement plate is installed at the output end of the transverse movement cylinder; a hole-blocking module is installed on the surface of the transverse movement plate, and this hole-blocking module is used for the hole-blocking work of the product headphone.

[0006] Preferably, an installation plate is fixedly connected to the surface of the fixing plate through bolts, and this installation plate is used to fix the carrier for placing the product during testing.

[0007] Preferably, support columns are installed at the corner positions at the bottom of the fixing plate through bolts, and these support columns facilitate the installation work of the fixing plate.

[0008] Preferably, the hole-blocking module is composed of a longitudinal movement cylinder, an adjustment groove, a hole-blocking cylinder and a hole-blocking head, and the longitudinal movement cylinder is fixedly connected to the surface of the transverse movement plate through bolts.

[0009] Preferably, adjustment grooves are formed on both sides of the longitudinal movement cylinder, and a hole blocking cylinder is fixed inside the adjustment groove by screws.

[0010] Preferably, the output end of the hole blocking cylinder is detachably connected with a hole blocking head, and the hole blocking head is used for the hole blocking work of the product earphone.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The MIC hole blocking mechanism for acoustic and electrical product testing fixes the carrier on the surface of the mounting plate by setting the pneumatic module and the hole blocking module. Then, the product earphone to be tested is placed on the carrier. After that, the transverse movement cylinder on the surface of the mounting frame works, and the transverse movement cylinder drives the transverse movement plate to move. When moving, it drives the hole blocking module to move. When the hole blocking module moves, the position of the hole blocking cylinder is adjusted through the adjustment groove on the longitudinal movement cylinder. After adjustment, the hole blocking cylinder drives the hole blocking head to move, so as to block and seal the product earphone to be tested.

[0018] The structure of a MIC hole-blocking mechanism for testing acoustic-electric products provided by the present utility model is as Figure 1 shown, including a fixing plate 1. An EVA sponge 13 is adhesively fixed on the surface of the fixing plate 1. The EVA sponge 13 is used to weaken the interference generated by the movement and collision of the entire mechanism. An installation plate 11 is fixedly connected to the surface of the fixing plate 1 through bolts. The installation plate 11 is used to fix the carrier for placing the product to be tested. Support columns 12 are installed at the corner positions at the bottom of the fixing plate 1 through bolts. The support columns 12 facilitate the installation work of the fixing plate 1.

[0019] During implementation, through the action of the EVA sponge 13, the interference generated by the movement and collision of the entire mechanism is weakened.

[0020] Furthermore, as Figure 2 and Figure 3 shown, pneumatic modules 2 are installed at both ends of the top of the fixing plate 1. The pneumatic module 2 is composed of an installation frame 21, a transverse movement cylinder 22, and a transverse movement plate 23. There are two groups of installation frames 21. The two groups of installation frames 21 respectively penetrate the EVA sponge 13 and are fixedly connected to both ends of the fixing plate 1. A transverse movement cylinder 22 is fixed on the surface of the installation frame 21, and a transverse movement plate 23 is installed at the output end of the transverse movement cylinder 22.

[0021] During implementation, the carrier is fixed on the surface of the installation plate 11. Then, the product earphone to be tested is placed on the carrier. After that, the transverse movement cylinder 22 on the surface of the installation frame 21 works, and the transverse movement cylinder 22 drives the transverse movement plate 23 to move. When moving, it drives the hole-blocking module 3 to move.

[0022] Furthermore, as Figure 3 and Figure 4As shown in the figure, a hole-blocking module 3 is installed on the surface of the transverse movement plate 23.

The output end of the hole-blocking cylinder 33 is detachably connected to a hole-blocking head 34, and this hole-blocking head 34 is used for the hole-blocking work of the product earphones.

[0023] During implementation, the position of the hole-blocking cylinder 33 is adjusted through the adjustment groove 32 on the surface of the longitudinal movement cylinder 31. After adjustment, the hole-blocking cylinder 33 drives the hole-blocking head 34 to move, thereby performing hole-blocking and sealing on the earphones of the product to be tested.

[0024] Working principle: When in use, the carrier is fixed on the surface of the mounting plate 11. Subsequently, the earphones of the product to be tested are placed on the carrier. Then, the transverse movement cylinder 22 on the surface of the mounting frame 21 works, and the transverse movement cylinder 22 drives the transverse movement plate 23 to move, and the hole-blocking module 3 is driven to move during the movement.

[0025] When the hole-blocking module 3 moves, the position of the hole-blocking cylinder 33 is adjusted through the adjustment groove 32 on the surface of the longitudinal movement cylinder 31.
