Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a sealing structure for a split speaker housing and a passive radiator. Background Technology

[0002] In the field of waterproof audio equipment, the conventional method for waterproofing speakers is to use a speaker frame with a silicone pad. The speaker frame is locked to the housing with screws, compressing the silicone pad between the two to form a waterproof wall that can withstand the water pressure required for the waterproof level, preventing water from entering the housing and thus achieving the purpose of waterproofing.

[0003] However, the method of using silicone pads between the speaker frame and the housing for waterproofing is only suitable for unibody speaker housings. For speaker housings that are molded separately and then assembled, even if silicone pads are used to waterproof the speaker frame, there will still be seams between the separately assembled speaker housing and the silicone pads. Liquid can still seep into the speaker housing through these seams and damage the internal components. It is clear that the waterproofing performance of separately assembled speaker housings needs to be further improved.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0044] Please refer to the following: Figures 1 to 8 The sealing structure 30 of the split speaker housing 10 and the passive radiator 20 provided in the embodiments of this application will now be described. The sealing structure 30 of the split speaker housing 10 and the passive radiator 20 includes: speaker housing 10, passive radiator 20 and sealing structure 30.

[0045] The speaker housing 10 has a front shell 11 and a rear shell 12 that can be assembled together. The front shell 11 and the rear shell 12 can surround the first mounting opening 13. The passive radiator 20 is fixedly installed in the first mounting opening 13. The sealing structure 30 includes a silicone sealing gasket 31 disposed between the passive radiator 20 and the first mounting opening 13 and a silicone sealing strip 32 disposed between the front shell 11 and the rear shell 12. The end of the silicone sealing strip 32 is bonded to the silicone sealing gasket 31.

[0046] Specifically, a silicone sealing gasket 31 is used to seal the gaps between the passive radiator 20 and the front shell 11 and rear shell 12, and a silicone sealing strip 32 is used to seal the gaps between the front shell 11 and rear shell 12. Simultaneously, the silicone sealing strip 32 and the silicone sealing gasket 31 are bonded together to form an irregularly shaped waterproof structure, which can simultaneously seal the gaps between the passive radiator 20, the front shell 11, and the rear shell 12, thereby further improving the speaker's waterproof sealing effect. Furthermore, since the silicone sealing strip 32 and the silicone sealing gasket 31 are bonded together, the gaps between the passive radiator 20, the front shell 11, and the rear shell 12 can be sealed, eliminating the need for adhesive application between the front shell 11 and the rear shell 12. The front shell 11 and the rear shell 12 can be repeatedly disassembled and reassembled, which improves the convenience of speaker maintenance.

[0047] In some embodiments of this application, a first mounting groove 14 is provided between the front shell 11 and the rear shell 12, and a first mounting protrusion 15 is provided between the two. The silicone sealing strip 32 is installed in the first mounting groove 14. After the front shell 11 and the rear shell 12 are assembled together, the first mounting protrusion 15 can be inserted into the first mounting groove 14 and abut against the silicone sealing strip 32.

[0048] For example, the first mounting groove 14 is provided on the rear side edge of the front shell 11, and the first mounting protrusion 15 is provided on the front side edge of the rear shell 12; after the front shell 11 and the rear shell 12 are assembled together, the first mounting protrusion 15 can be inserted into the first mounting groove 14.

[0049] Specifically, the silicone sealing strip 32 includes a first sealing strip 321 disposed at both ends of the first mounting groove 14 and a second sealing strip 322 disposed in the first mounting groove 14 and located between the two first sealing strips 321. One end of the first sealing strip 321 and one end of the second sealing strip 322 can be connected to each other, and the other end of the first sealing strip 321 is bonded to the silicone sealing gasket 31.

[0050] For example, the silicone sealing gasket 31 is provided with an adhesive layer. Before the silicone sealing gasket 31 is inserted into the first mounting port 13, the release paper of the adhesive layer needs to be removed. Then, the silicone sealing gasket 31 is bonded to the first mounting port 13 using the adhesive layer, and the end of the first sealing strip 321 is bonded to the adhesive layer.

[0051] Preferably, the first sealing strip 321 and the second sealing strip 322 have the same thickness, the width of the first mounting protrusion 15 is two-thirds of the depth of the first mounting groove 14, and the thickness of the first sealing strip 321 is half the width of the first mounting protrusion 15. This structure allows the first mounting protrusion 15 to be inserted into the first mounting groove 14, compressing the first sealing strip 321 and the second sealing strip 322, thereby improving the sealing effect between the first mounting protrusion 15 and the first mounting groove 14 and enhancing the sealing and waterproofing performance.

[0052] In some other embodiments of this application, after the front shell 11 and the rear shell 12 are assembled together, they at least form a first mounting chamber 101 for mounting components. The first mounting chamber 101 extends through the left and right sides of the front shell 11 and the rear shell 12 to form a first mounting opening 13. The first mounting groove 14 has a first notch 141 on the side facing the first mounting chamber 101. The front shell 11 or the rear shell 12 has an elastic clamping arm 142 on one side of the first notch 141. When one end of the first sealing strip 321 is connected to one end of the second sealing strip 322, it can pass through the first notch 141 and be clamped and fixed by the elastic clamping arm 142.

[0053] Specifically, by setting the first notch 141 and the elastic clamping arm 142, the first sealing strip 321 and the second sealing strip 322 can be tightened and fixed to prevent the first sealing strip 321 and the second sealing strip 322 from falling off when the front shell 11 and the rear shell 12 are disassembled and assembled, thereby improving the convenience of disassembling and assembling the front shell 11 and the rear shell 12.

[0054] Preferably, the first mounting groove 14 extends laterally and penetrates the side of the first mounting opening 13, and a first detour groove 143 is provided between the first mounting opening 13 and the first mounting groove 14; the other end of the first sealing strip 321 is bent to form a first detour portion 3211, which can be inserted into the first detour groove 143, and the first detour portion 3211 is bonded to the silicone sealing gasket 31. The two ends of the first mounting protrusion 15 are provided with first detour protrusions 151, which can be inserted into the first detour groove 143, and the width of the first detour protrusion 151 is the same as the width of the first mounting protrusion 15.

[0055] Specifically, by providing the first detour groove 143 and the first detour protrusion 151 to accommodate the first detour portion 3211, the sealing effect between the passive basin 20, the front shell 11 and the rear shell 12 can be further improved.

[0056] More specifically, the passive basin 20 is provided with a first plane 21, which is parallel to the side of the first mounting port 13; one side of the sealing silicone pad 31 abuts against the first plane 21, and the other side of the sealing silicone pad 31 abuts against the side of the first mounting port 13.

[0057] In other embodiments of this application, the passive basin 20 is provided with a first through hole 22, the sealing silicone gasket 31 is provided with a second through hole 311, and the first mounting port 13 is provided with a first screw hole 131. The first through hole 22, the second through hole 311, and the first screw hole 131 are coaxially arranged. The front shell 11 is provided with a first support post 16, and the rear side of the first support post 16 is provided with a first insertion post 161, which is provided with a second screw hole 162. The rear shell 12 is provided with a second support post 17, which is provided with a first insertion hole 171 for the first insertion post 161 to be inserted and a first through hole 172 for a screw to pass through and be screwed into the second screw hole 162.

[0058] Detailed description of the assembly method of the separate speaker enclosure 10 and the sealing structure 30 of the passive radiator 20 provided in this application:

[0059] First, the first sealing strip 321 and the second sealing strip 322 are installed into the first assembly groove 14, and one end of the first sealing strip 321 and the second sealing strip 322 are connected together, pulled out from the first notch 141 and snapped into the elastic clamping arm 142.

[0060] Then, the other end of the first sealing strip 321 is folded in half to form the first detour portion 3211, and the first detour portion 3211 is inserted into the first detour groove 143;

[0061] Furthermore, the front shell 11 and the rear shell 12 are assembled together, such that the first mounting protrusion 15 is inserted into the first mounting groove 14 and the first detour protrusion 151 is inserted into the first detour groove 143, so as to compress the first sealing strip 321 and the second sealing strip 322, thereby completing the sealing between the front shell 11 and the rear side.

[0062] Then, remove the release paper from the side of the silicone sealing gasket containing the adhesive layer, then stick the adhesive layer to the first mounting opening 13, and stick the first detour 3211 to the adhesive layer, and complete the sealing between the passive basin 20, the front shell 11 and the rear shell 12 through the first detour 3211.

[0063] Finally, the passive basin 20 is installed in the first mounting port 13, so that the passive basin 20 is tightly attached to the silicone sealing gasket, and the passive basin 20 is locked in the first mounting port 13 with screws; when tightening the screws, it is necessary to ensure that the tightening force of each screw is consistent, so as to ensure that the passive basin 20 is stacked with the silicone sealing gasket at all positions.
