Description

Technical Field

[0001] The utility model relates to the technical field of tooling and fixtures for testing electroacoustic devices, in particular to a speaker module testing tooling. Background Art

[0002] With the popularity of smart phones and mobile devices, the market demand for speaker modules continues to increase. At the same time, more and more users want their devices to be waterproof to avoid damage to the device due to accidental water drop during use. For this reason, existing speaker modules need to be tested for waterproof performance.

[0003] Testing the waterproof performance of the speaker module is achieved by testing its air tightness. The existing speaker module testing tooling includes a base, a driving member arranged on the base, and a test block connected to the driving member. The base is provided with a placement slot for placing the speaker module to be tested. The test block is located on one side of the placement slot and is driven by the driving member to approach or move away from the placement slot to contact or move away from the sound outlet of the speaker module to be tested. At present, the side where the sound outlet of most side-sounding speaker modules is located is an inclined surface. However, the inclination of the inclined surface is not necessarily the same in different speaker modules. Therefore, in actual testing, different test heads need to be replaced to adapt to different speaker modules. It can be seen that the existing speaker module testing tooling has the problem of poor versatility. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a loudspeaker module testing tool with strong versatility.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a speaker module testing tool, comprising:

[0006] A base, wherein the base is provided with a boss, and a top surface of the boss is provided with a placement groove for placing the speaker module to be tested;

[0007] A resistance block, wherein one end of the resistance block is provided with a resistance inclined surface, the resistance inclined surface is provided with a first air outlet, the other end of the resistance block is provided with a first inflation port connected to the first air outlet, and two sides of the resistance inclined surface are respectively provided with a straight-shaped through hole;

[0008] An inflatable block, wherein one end of the inflatable block close to the abutment block is provided with a second air outlet and two groups of mounting holes, the two groups of mounting holes correspond one to one with the two I-shaped through holes, the second air outlet is located between the two groups of mounting holes, each group of mounting holes includes a plurality of mounting screw holes, and a second inflatable port connected to the second air outlet is provided on the surface of the inflatable port;

[0009] a transfer ball, the transfer ball is located between the abutment block and the inflatable block and abuts against the abutment block and the inflatable block respectively, the transfer ball is provided with an air flow channel, one end of the air flow channel is connected to the second air outlet, and the other end of the air flow channel is connected to the first inflatable port;

[0010] A fastening screw, each of the mounting screw holes is correspondingly installed with the fastening screw, and the tail end of the fastening screw passes through the I-shaped through hole and is connected to the mounting screw hole;

[0011] A driving member is disposed on the base and connected to the inflatable block to drive the resistance block to approach or move away from the placement groove.

[0012] Furthermore, the second air outlet and the first air filling port are respectively tapered.

[0013] Furthermore, two first sealing gaskets are included, one of which is arranged between the transfer ball and the abutment block, and the other of which is arranged between the transfer ball and the inflatable block.

[0014] Furthermore, it also includes a second sealing gasket, which is arranged on the interference slope, and the hollow area of ​​the sealing gasket is arranged corresponding to the first air outlet.

[0015] Furthermore, one end of the abutment block close to the inflatable block is a convex arc surface, and one end of the inflatable block close to the abutment block is a concave arc surface.

[0016] The beneficial effect of the utility model is that the tester can first loosen the fastening screws, then adjust the pitch angle of the resistance block relative to the inflatable block, and then tighten each fastening screw to maintain the pitch degree of the resistance block, so that the resistance block can adapt to the speaker module to be tested with different inclined surface inclinations, effectively improving the versatility of the speaker module testing tooling.

[0017] It is easy to understand that when the pitch degree of the interference block relative to the inflatable block is different, the tightening degree of each fastening screw or the depth of screwing into the mounting screw hole is different, so that the interference block can maintain different pitch angles relative to the inflatable block.

[0018] In addition, the advantage of arranging the second inflation port connected to the air source on the inflation block is that the second inflation port is kept away from the interference slope, preventing the air path and air pipe from affecting the pitch adjustment of the interference block, thereby reducing the pitch adjustment limit range of the interference block, which is conducive to further improving the versatility of the speaker module test tooling.

[0031] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0032] Please refer to Figures 1 to 4 , a speaker module testing tool, comprising:

[0033] A base 1, wherein the base 1 is provided with a boss, and a top surface of the boss is provided with a placement groove 11 for placing a speaker module to be tested;

[0034] A resistance block 2, wherein one end of the resistance block 2 is provided with a resistance inclined surface 21, the resistance inclined surface 21 is provided with a first air outlet 22, the other end of the resistance block 2 is provided with a first inflation port 23 connected to the first air outlet 22, and two sides of the resistance inclined surface 21 are respectively provided with a straight-line through hole 24;

[0035] An inflatable block 3, wherein one end of the inflatable block 3 close to the abutment block 2 is provided with a second air outlet 31 and two groups of mounting holes, the two groups of mounting holes correspond one to one with the two I-shaped through holes 24, the second air outlet 31 is located between the two groups of mounting holes, each group of mounting holes includes a plurality of mounting screw holes 32, and a second inflatable port 33 communicating with the second air outlet 31 is provided on the surface of the inflatable port;

[0039] From the above description, it can be seen that the beneficial effect of the utility model is that the tester can first loosen the fastening screws, and then adjust the pitch angle of the conflict block 2 relative to the inflatable block 3, and then lock each fastening screw to maintain the pitch degree of the conflict block 2, so that the conflict block 2 can be adapted to the speaker module to be tested with different slopes, effectively improving the versatility of the speaker module test tooling. It is easy to understand that when the pitch degree of the conflict block 2 relative to the inflatable block 3 is different, the fastening degree of each fastening screw or the depth of screwing into the mounting screw hole 32 is different, so that the conflict block 2 can maintain different pitch angles relative to the inflatable block 3. In addition, the benefit of arranging the second inflation port 33 connected to the air source on the inflatable block 3 is to keep the second inflation port 33 away from the conflicting inclined surface 21, avoid the air path air pipe affecting the pitch adjustment of the conflict block 2, resulting in the pitch adjustment limit range of the conflict block 2 being reduced, which is conducive to further improving the versatility of the speaker module test tooling.
