Referring to fig. 1 and 2, a waterproof case for a bluetooth speaker according to a preferred embodiment of the present invention will be described in detail below, wherein the waterproof case for a bluetooth speaker includes a first case 10 and a second case 20, that is, the waterproof case for a bluetooth speaker is a detachable assembly design.

Wherein the first casing 10 has a first casing cavity 101 and a first side wall 11 and a first bottom wall 12 surrounding the first side wall 11 and the first bottom wall 12 forming the first casing cavity 101, wherein an end of the first side wall 11 away from the first bottom wall 12 is a first end 111, and the first end 111 is provided with a groove 102 along a circumferential direction of the waterproof casing, wherein the groove 102 is preferably arranged at a position close to a center line of the first end 111 in order to ensure or improve a structural strength of the groove 102 and thus ensure a reliability of a waterproof seal of the waterproof casing of the loudspeaker box.

The second housing 20 has a second housing cavity 201 matching with the first housing cavity 10, and a second sidewall 21 and a second bottom wall 22 surrounding the second housing cavity 201, wherein an end of the second sidewall 21 away from the second bottom wall 22 is a second end 221, and meanwhile, the second housing 20 is provided with a protrusion structure 23 matching with the groove 102 at the second end 221, and the protrusion structure 23 is a soft member and is in interference fit with the groove 102. Therefore, through protruding structure 23 with the cooperation of recess 102 on the first casing 10, reach the sealed effect between structure and the structure, not only can avoid the sealed condition of losing efficacy of various seals that has of conventional sealed glue, the failure rate is reduced by a wide margin, also need not the quantity of sealed glue between the carelessness or the accurate control casing simultaneously or carry out the surface treatment after the excessive glue, on the basis that possesses the sealed effect of strong effect, the assembly is simpler, and is convenient, can practice thrift the manufacturing time, reduce manufacturing cost.

As a preferred embodiment, the protruding structure 23 and the groove 102 are in interference fit in the depth direction of the groove 102, and in clearance fit in the width direction of the groove 102, wherein the width direction is a direction perpendicular to the depth direction. Therefore, in the process of assembling the first casing 10 and the second casing 20, based on the soft property of the protruding structure 23, the protruding structure 23 is extruded in the groove 102 and gradually and automatically spreads to the periphery, that is, the periphery of the groove 102, so that the first casing 10 and the second casing 20 can be well butt-assembled and molded, and meanwhile, the extruded part of the protruding structure 23 in the groove 102 can also play an auxiliary sealing effect on the periphery of the groove 102, thereby further improving the waterproof sealing performance of the waterproof casing of the sound box.

Further preferably, the second housing 20 is composed of a hard portion 210 and a soft portion 220, wherein the soft portion 220 wraps around an outer side wall of the hard portion 210, and the convex structure 23 is integrally formed with the soft portion 220. Therefore, the manufacturing and molding of the second casing 20 are facilitated, and meanwhile, the protruding structure 23 and the soft portion 220 have good structural stability and structural strength, so that the waterproof and sealing performance of the waterproof casing of the sound box is better on the basis that the hard portion 210 provides a certain supporting strength.

The soft portion 220 may be made of TPU or silicone. The hard portion 210 may be formed of a PC material or an ABS material.

Further preferably, the hard portion 210 is provided with a step 24 at a portion close to the outer side of the second end portion 221, wherein the step 24 extends toward a direction close to the second bottom wall 22 and is configured to bear the soft portion 220, so that a connection cross-sectional area between the protrusion structure 23 and the soft portion 220 is larger through a clearance effect of the step 24, and thus, the connection strength and the connection stability are stronger, and reliability of the waterproof sealing performance of the waterproof enclosure of the sound box is ensured.

Further preferably, the width of the step 24 is larger than the width of the protruding structure 23. In this way, when the first housing 10 and the second housing 20 are assembled, the step 24 can apply a better and more stable force to the protruding structure 23, and thus the interference fit between the protruding structure 23 and the first housing 10 in the depth direction of the groove 102 can be ensured.

Further preferably, the raised structure 23 is implemented as a waterproof rib.

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.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention.
