Description

Technical Field

[0001] The utility model relates to the field of testing devices, and particularly relates to a waterproof testing tooling. Background Art

[0002] A loudspeaker is an electroacoustic device that converts an audio electrical signal into a sound signal under the condition of no sound leakage (or a type 3.2 high / low leakage ring according to ITU standards), and is widely used in communication terminal devices such as mobile phones, fixed phones, and hearing aids to realize audio (voice, music) playback. For example, a moving coil loudspeaker has a working principle (physical principle) similar to that of a traditional moving coil loudspeaker: a changing audio electrical signal is fed into a voice coil, the voice coil is placed in the magnetic gap of a permanent magnet magnetic circuit, and the voice coil vibrates up and down under the drive of a changing electromagnetic field force (Lorentz force) generated by the changing current, and drives the vibration diaphragm to drive the air back and forth to generate sound waves.

[0003] After the production of the loudspeaker is completed, it is necessary to test the waterproof performance to meet the waterproof performance of the loudspeaker. However, the existing loudspeaker test is a forward test. Under the forward test, in order to ensure the sealing performance, the edge of the product will be pressed. However, the edge structure of the product has low strength and is easy to deform. In actual use of the product, the edge structure is not stressed. Therefore, the forward test result cannot be fully related to the actual situation, and it is easy to cause a loudspeaker that meets the requirements to be misjudged as unqualified during the test due to edge deformation. In addition, the loudspeaker is also easy to be damaged during the test, resulting in losses in production testing, both of which increase the production cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof testing tooling, aiming to improve the problem that the existing waterproof testing method is easy to cause damage or injury to the loudspeaker.

A detection hole penetrating through the sealing gasket is provided on the bottom surface of the product slot, and a sealing joint or a sealing socket is provided at the inlet end of the detection hole; and

[0007] A fixing frame, which includes a sealing plate and a top pressing plate. The sealing plate is provided with a limiting hole for the loudspeaker to expose; the top pressing plate is arranged on the sealing plate, and a convex block for pressing against the loudspeaker is arranged on the top pressing plate.

[0008] Preferably, at least one positioning groove is provided on the top surface of the sealing plate, and a protrusion engaging with the positioning groove is provided on the top pressing plate.

[0009] Preferably, two finger slot holes are symmetrically arranged on the limiting hole.

[0010] Preferably, a plurality of locking holes in alignment are arranged on the sealing plate and the base.

[0011] Preferably, a test slot is arranged in the middle of the plate surface of the sealing plate, a plurality of the locking holes are arranged at the end of the plate surface of the sealing plate, and the limiting hole is arranged at the bottom of the test slot.

[0012] Preferably, the detection hole includes a vertical blind hole section and an air supply section communicating with the blind hole section, and an air inlet of the air supply section is arranged on the side surface of the fixing frame;

[0013] The hole diameter of the air supply section is larger than that of the blind hole section.

[0014] Preferably, an assembly groove is arranged on the base and a core block is fitted and placed in the assembly groove. The product card slot is arranged on the core block, and the detection hole extends from the core block to the base.

[0015] Preferably, a soft layer is arranged on the top abutting surface of the bump.

[0036] Embodiment

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in ,

[0038] , ,

[0039] and , this embodiment provides a waterproof test tooling, which includes a base 10 and a fixing frame 20. A product card slot 101 for placing a speaker is arranged on the base 10. A gasket 1011 for sealing with the speaker is arranged at the bottom of the product card slot 101. A detection hole 102 penetrating through the gasket 1011 is arranged on the bottom surface of the product card slot 101. A sealing joint or a sealing jack is arranged at the inlet end of the detection hole 102. The fixing frame 20 includes a sealing plate 201 and a top pressing plate 202. The sealing plate 201 is provided with a limiting hole 2011 for the speaker to expose. The top pressing plate 202 is arranged on the sealing plate 201, and a convex block 2021 for pressing against the speaker is arranged on the top pressing plate 202.

[0038] In this embodiment, the speaker is placed into the product card slot 101 to achieve limiting installation (the contour of the product card slot 101 is the same as the contour size of the speaker). The mating edge is sealed through the gasket 1011 to prevent air leakage, so that a good airtightness is achieved between the detection hole 102 and the product to be detected, ensuring the accuracy of the detection. The sealing joint and the sealing jack at the port of the detection hole 102 can be the joint or the jack structure of a fluid connection valve (such as the through-board quick-connect female seat and joint of the RS-PLC series), so that a quick sealing connection can be formed, improving the operation convenience. Therefore, gas is introduced into the speaker through the detection hole 102 to detect the airtightness, and the waterproof performance level or the corresponding performance situation can be obtained through calculation (this calculation is existing and not the content to be protected by this application, so it will not be elaborated here).

[0039] Furthermore, the fixing frame 20 is divided into a sealing plate 201 and a top pressing plate 202. The top of the speaker is limited through the sealing plate 201. By replacing different sealing plates 201, speakers of different sizes can be adapted, so that the convex block 2021 of the top pressing plate 202 can be aligned and pressed against for cooperation, and at the same time, damage to the speaker is avoided, improving the practicability.

[0040] As Figure 4 shown, at least one positioning groove 2012 is arranged on the top surface of the sealing plate 201 in this embodiment, and a protrusion 2022 engaged with the positioning groove 2012 is arranged on the top pressing plate 202. Through the cooperation of the positioning groove 2012 and the protrusion 2022, accurate positioning and assembly can be carried out, so that the convex block 2021 can accurately position and press against the speaker, avoiding too large or too small pressing force between the convex block 2021 and the speaker, and improving the use convenience.

[0041] As Figure 4 and Figure 5 shown, in this embodiment, two finger slot holes 2013 are symmetrically arranged on the limit hole 2011. Through the finger slot holes 2013, it is convenient to take or place the speaker, improving the convenience of use.

[0042] As Figure 2 , Figure 4 and Figure 5 shown, in this embodiment, a plurality of aligned locking holes 30 are provided on the sealing plate 201 and the base 10. In this way, alignment lamination can be carried out through bolts or positioning pins, and at the same time, the assembly between the sealing plate 201 and the base 10 can be made stable, so that the speaker can be smoothly placed in the detection hole 102, improving the convenience of use.

[0043] Furthermore, as Figure 2 and Figure 4 shown, in this embodiment, a test slot 2014 is provided in the middle of the plate surface of the sealing plate 201, a plurality of locking holes 30 are provided at the end of the plate surface of the sealing plate 201, and the limit hole 2011 is provided at the bottom of the test slot 2014. The design of the test slot 2014 can facilitate observing whether the convex block 2021 covers or abuts against the speaker, and at the same time, the thickness of the test slot 2014 can be set to adapt to speakers of different sizes. At the same time, cooperating with the protrusion 2022 on the top pressing plate 202, a visible through opening can be formed between the test slot 2014, and it is convenient to take or place the top pressing plate 202, improving the practicality.

[0044] As Figure 2 shown, in this embodiment, the detection hole 102 includes a vertical blind hole section 1021 and an air supply section 1022 communicating with the blind hole section 1021. The air inlet of the air supply section 1022 is provided on the side surface of the fixing frame 20; the hole diameter of the air supply section 1022 is larger than the hole diameter of the blind hole section 1021. Through the setting of the air supply section 1022, the air inlet can be arranged at the side position of the base 10 to facilitate connecting the detection air pipe, providing corresponding convenience. And the diameter of the blind hole section 1021 is relatively small. In this way, when the air exits, the air volume is sufficient (the air pressure is relatively large), which can ensure the stable air volume during detection and improve the stability of detection.

[0045] As Figure 2 and Figure 6As shown in the figure, in this embodiment, an assembly groove 103 is provided on the base 10, and a die core block 104 is fitted and placed in the assembly groove 103. The product card slot 101 is provided on the die core block 104, and the detection hole 102 extends from the die core block 104 to the base 10. The design of the die core block 104 enables the base 10 to form two parts. By replacing different die core blocks 104, product card slots 101 for different models of products can be designed on the die core block 104. By replacing the die core block 104, the test effect of different models of speakers can be achieved, and the purpose of improving the flexibility of use can be achieved.

[0046] In this embodiment, a soft layer (not shown), such as a silicone or rubber layer, is provided on the abutting surface of the convex block 2021, which can avoid damage to the speaker when limiting the position of the speaker, thereby improving the practicability.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
