Description

High-efficient waterproof casing of bluetooth speaker

Technical Field

The invention relates to the technical field of wireless Bluetooth sound boxes, in particular to a high-efficiency waterproof shell of a Bluetooth sound box.

Background

With the rapid development of the Bluetooth sound box, the form of the Bluetooth sound box is more and more abundant; in order to obtain better playing tone quality and use experience, the passive radiators are arranged on two sides of the Bluetooth sound box, the upper shell material and the lower shell material are poor in matching section due to unavoidable structural tolerance, the passive radiators are not easy to seal after being assembled, the precision is limited, and deep water proofing cannot be achieved; one is to make the main body of the sound box into a complete main body, both ends are opened, fix the passive radiator at the opening, the disadvantage is to assemble all parts on the main body intensively, lead to the major structure limitation to be large, the mould is complicated, the production assembly is difficult, the non-defective rate is low, the passive radiator is located the waterproof sound box of both ends of the product side, one is to cut the sound box from the middle, the A/B shell material of the sound box is locked together through the screw, and then fix the passive radiator on the side, but the upper and lower shell material can't avoid producing the tolerance because of moulding plastics or production reason, both cooperate and have slight section difference, the passive radiator is fixed on the level with section difference, produce the interval easily, reduce the waterproof performance, if fill up the tolerance interval with glue, glue can glue will glue upper and lower shell material and passive radiator three together, cause the maintenance difficulty, shell material and passive radiator will scrap because of disassembling, the utility model provides a make things convenient for the waste of material and the rising of cost one is cut open the audio amplifier from the middle, on the audio amplifier, the inferior valve material passes through the screw lock together, fix passive radiator in the side again, nevertheless, inferior valve material is because of moulding plastics or production reason, can avoid producing the tolerance, both cooperations have slight segment difference, passive radiator fixes on the plane that has the segment difference, produce the clearance easily, reduce waterproof performance, if fill up the tolerance clearance with glue, glue can be with last, inferior valve material is in the same place with the bonding of passive radiator three, cause the maintenance difficulty, shell material and passive radiator can be scrapped because of disassembling, cause the waste of material and the rising of cost, for this reason, provide a bluetooth speaker's high-efficient waterproof casing.
