It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 to 3, the utility model provides a prevent strutting waterproof sound box 100 in gap, including preceding shell 10, backshell 20, speaker panel 30, high pitch panel 40, dust cover 50 and waterproof sealing ring 60, speaker panel 30 and high pitch panel 40 are all fixed and are installed on preceding shell 10, dust cover 50 is installed in the upper end of preceding shell 10.
The edge of the rear shell 20 is provided with an embedded step 21, the bottom of the embedded step 21 is provided with a waterproof groove 22, the bottom of the waterproof groove 22 is also provided with a glue overflow groove 23, and the groove width of the glue overflow groove 23 is smaller than that of the waterproof groove 22. The waterproof sealing ring 60 is embedded in the waterproof groove 22, the front shell 10 is clamped on the rear shell 20, and the bottom end edge of the front shell 10 is attached to the bottom of the embedding step 21. The sealing ring fitted in the waterproof groove 22 is deformed by being pressed when the front case 10 and the rear case 20 are engaged with each other. If the waterproof groove 22 is not enough to accommodate the deformed waterproof gasket 60, the excess portion of the waterproof gasket 60 will extend into the glue overflow groove 23 and will not extend to the outside along the gap between the front and rear cases 10 and 20.
The bottom of the rear shell 20 is further provided with an air-permeable groove 24 which is recessed inwards, and the bottom of the air-permeable groove 24 is further provided with an inverter tube 25 which extends towards the inside of the rear shell 20.
