Embodiment
Below in conjunction with drawings and the specific embodiments, with regard to the technical solution of the utility model, be described further.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
See figures.1.and.2, Fig. 1 is the part-structure schematic diagram of the utility model sound cavity shell the first embodiment, and Fig. 2 is the part-structure schematic diagram of the utility model sound cavity shell the second embodiment.
The present embodiment proposes a kind of sound cavity shell, comprise the first housing unit 10 and the second housing unit 20, on described the first housing unit 10, be provided with rib 11 is installed, on described the second housing unit 20, be provided with mounting groove 21, described sound cavity shell also comprises seal 30, and described seal 30 has the storage tank 31 of accommodating described installation rib 11; Described seal 30 is sheathed on described installation rib 11, and is placed in described mounting groove 21, described mounting groove 21 and the installation rib 11, the storage tank 31 and installation rib 11 interference fit that are arranged with seal 30.
Seal 30 can be with the first housing unit 10 on the sealing ring of installation rib 11 shape adaptations, good water-proof effect, when processing difform sealing ring for different sound chambeies, cost is higher; The seal 30 is also sealing strip, processing cost is lower, but because sealing strip is sheathed on while installing on rib 11, the seam crossing waterproof effect of the head end of sealing strip and end is poor, can one holddown groove be set at the top that rib 11 is installed, the head end of sealing strip and end are fixed in described holddown groove.Described seal 30 is preferably sealing strip, and cost is lower.
The first housing unit 10 in this first sound cavity shell and the second housing unit 20 can be respectively sound chamber upper cover and sound chamber lower cover as shown in Figure 1, because water-proof function can be realized in the sound chamber of sound chamber upper cover and sound chamber lower cover composition, now the seal 30 between the first sound chamber upper cover and sound chamber lower cover plays the effect of waterproof and damping; This first housing unit 10 and the second housing unit 20 also can be respectively iron net and sound chamber lower cover as shown in Figure 2, the sound chamber forming due to iron net and sound chamber lower cover does not have water-proof function, and now the seal 30 between iron net and sound chamber lower cover plays the effect of damping.
The sound cavity shell that the present embodiment proposes, comprises the first housing unit 10 and the second housing unit 20, is provided with rib 11 is installed on described the first housing unit 10, on described the second housing unit 20, is provided with mounting groove 21; Also comprise seal 30, described seal 30 has the storage tank 31 of accommodating described installation rib 11; Described seal 30 is by the sheathed described installation rib 11 of described storage tank 31, and is placed in described mounting groove 21, described mounting groove 31 be arranged with installation rib, the storage tank 31 of seal and rib 11 interference fit be installed.Seal 30 is directly sheathed on to installation rib 11 upper of the first housing unit 10 by storage tank 31, then the first housing unit 10 is connected with the second housing unit 20, install very conveniently, when saving human cost, improve the production efficiency of audio frequency apparatus.
With reference to Fig. 3, for improving sealing and damping effect, the opening part width of described storage tank 31 is less than the thickness of described installation rib 11 further.
When seal 30 is sheathed on the installation rib 11 of the first housing unit 10, because the top width of the storage tank 31 of seal 30 is less than the thickness that rib 11 is installed, the sidewall that 11 pairs of storage tanks 31 of rib are installed produces pressure, the sidewall of storage tank 31 is under the effect of reaction force, tightly be attached at the outer surface of described installation rib 11, make sealing and damping effect better.
With reference to Fig. 4, for improving sealing and damping effect, the two side of described storage tank 31 is extended with kink 32 relatively further, and in the present embodiment, kink 32 is positioned at the opening part of storage tank 31.
In the present embodiment, the thickness of kink 32 is preferably the sidewall thickness that is less than storage tank 31, rib 11 is installed more easily to be inserted in the storage tank 31 of seal 30, two side due to storage tank 31 is extended with kink 32 relatively simultaneously, make the sidewall of storage tank 31 more be close to the outer surface that rib 11 is installed, make sealing and damping effect better.
Further with reference to Fig. 5, improving under the prerequisite of sealing and damping effect, for a sidewall of storage tank 31 described in saving material is extended with kink 32 to another sidewall direction, in the present embodiment, kink 32 is positioned at the opening part of storage tank 31.
In the present embodiment, the thickness of kink 32 is preferably the sidewall thickness that is less than storage tank 31, rib 11 is installed more easily to be inserted in the storage tank 31 of seal 30, relative another sidewall of a sidewall due to storage tank 31 is extended with kink 32 simultaneously, make the sidewall of storage tank 31 more be close to the outer surface that rib 11 is installed, make sealing and damping effect better, save the material of storage tank 31 sidewalls, to reduce cost simultaneously.
The utility model also proposes a kind of audio frequency apparatus, comprises the sound cavity shell described in above embodiment.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
