Appearance piece 30 is implemented when the leaded light post, and after the waterproof casing of bluetooth speaker started, perhaps during the broadcast music, perhaps when broadcasting the music of different styles, the inside components and parts of casing can release different light or color to the external world through the leaded light post, instruct the state of different music styles or casings, make things convenient for the customer to use.
More specifically, the first casing 10 is a hard member, such as a hard plastic member, such as a device manufactured and molded by a PC material or an ABS material, etc., and forms an inner side wall of the waterproof casing of the bluetooth sound box, and the first casing wall 11 of the first casing 10 is provided with at least one first through hole 101. Generally, the first through hole 101 is provided as one and located on a side wall of the waterproof case of the bluetooth speaker. Obviously, the first through hole 101 may also be provided in plurality, and at the same time, may also be provided in the bottom wall of the waterproof bluetooth speaker housing, or in both the side wall and the bottom wall of the waterproof bluetooth speaker housing.
The second casing 20 is a soft component, such as a soft rubber component, and is attached to the outer wall of the first casing 10 to form the outer side wall of the waterproof casing, such as a device formed by manufacturing TPU materials or silica gel materials, and the second casing 20 is provided with a second through hole 201 corresponding to the first through hole 101. For convenience of introduction, the waterproof housing is referred to as a waterproof housing of a bluetooth sound box with an appearance piece.
The appearance member 30 is matched with the first through hole 101 and the second through hole 201, inserted into the first through hole 101 and the second through hole 201, and in interference fit with the second through hole 201.
In this way, the appearance piece 30 is conveniently arranged in the first through hole 101 and the second through hole 201 through the matching relationship between the appearance piece 30 and the second through hole 201, and meanwhile, through the interference fit relationship between the appearance piece 30 and the second through hole 201, the structural connection relationship and the connection strength between the appearance piece 30 and the waterproof housing can be strengthened, so that the appearance piece 30 is not easy to drop and is more firmly connected, meanwhile, through the interference fit relationship between the appearance piece 30 and the second through hole 201, a good structural seal can be formed, the waterproof sealing performance of the waterproof housing is ensured, and a higher waterproof grade is achieved, for example, the waterproof requirement of IPX7 grade is met.
As a preferred embodiment, when the exterior member 30 is implemented as a light guide, the outer end of the exterior member 30 is flush with the outer sidewall of the second casing 20, or is recessed into the outer sidewall of the second casing 20.
Further preferably, when the exterior element 30 is implemented as a light guide pillar, the light guide pillar has a light receiving limiting portion 31 and a light guide extending portion 32, wherein the light receiving limiting portion 31 is attached to the inner side wall of the first housing 10 or is connected to the inner side wall of the first housing 10 by a fastening member, such as a fastening screw, and the outer diameter of the light receiving limiting portion 31 is larger than the aperture of the first through hole 101, so as to prevent the exterior element 30 from falling off the waterproof housing or from the first through hole 101 and the second through hole 201; in addition, the light guide extension 32 is located in the first through hole 101 and the second through hole 201, and is in interference fit with the second through hole 201, and is used for guiding light to the external environment.
Further preferably, the first housing 10 and the second housing 20 are integrally injection molded. Generally, the two-shot molding is performed by integral injection molding. The double-color injection molding is a molding process for injecting two different materials into the same set of mold, so that the injection molded part is formed by the two materials, wherein some two materials are different in color, and some two materials are different in hardness, and therefore the attractiveness and the assembly performance of the product are improved. In the waterproof bluetooth speaker housing with an appearance provided in the present application, the first housing 10, which is hard, provides a better structural support strength, and the second housing 20, which is soft, provides convenience for installing the appearance 30, and also provides convenience for reliable sealing.
As a preferred embodiment, the second casing 20 is further provided with an interference sealing sleeve 21, wherein the interference sealing sleeve 21 extends from the hole wall of the second through hole 201 to the inner wall of the first through hole 101 to be close to the inner side wall of the first casing 10, meanwhile, the light guiding extension 32 is inserted in the interference sealing sleeve 21 and is in interference fit with the interference sealing sleeve 21, and the interference sealing sleeve 21 is in transition fit with the first through hole 101, so that the interference contact area between the light guiding extension 32 and the second casing 20 is further increased through the interference sealing sleeve 21, the waterproof sealing performance between the appearance 30 and the waterproof casing is enhanced, and the transition contact area between the interference sealing sleeve 21 and the first casing 10 enhances the structural connection strength between the appearance 30 and the waterproof casing, thereby indirectly enhancing the structural connection strength between the appearance 30 and the waterproof casing of the bluetooth speaker, and preventing the appearance 30 from falling off. In general, after the first housing 10 and the second housing 20 are manufactured and molded by a two-shot molding process, the exterior member 30 is inserted into the first through hole 101 and the second through hole 201.
As another preferred embodiment, referring to fig. 3, an enlarged schematic view of a portion a in fig. 2 is shown, in which the overlapped portion between the interference seal sleeve 21 and the second housing 20 is the interference fit contact portion between the light guide extension 32 and the interference seal sleeve 21, and the interference fit contact portion between the light guide extension 32 and the second through hole 201, which is different from the foregoing embodiments in that: the interference sealing sleeve 21 extends from the hole wall of the second through hole 201 to the inner wall of the first through hole 101 to be flush with the inner side wall of the first housing 10. In this way, the contact area between the appearance member 30 and the interference seal sleeve 21 can be increased to the greatest extent within a limited space range, and the structural connection strength, the structural stability and the waterproof sealing performance of the entire waterproof housing can be increased to the greatest extent possible.
Further preferably, the second housing 20 is integrally injection molded with the interference seal sleeve 21.
It should be noted that the terms "first and second" in the present invention are used for descriptive purposes only, do not denote any order, are not to be construed as indicating or implying any relative importance, and are to be interpreted as names.
