The inventor finds that the shapes of common products in the market are side-sounding MIC holes, so that the dust screen is required to be pasted on the side wall of the shell for dust prevention during design, and the MIC sound outlet channel is sealed by designing an MIC sealing rubber sleeve generally so as to be in interference assembly with the dust screen to achieve the effects of sealing and dust prevention.

The MIC sealing rubber sleeve and the dust screen require 0.15 interference amount to be effectively sealed, so that in the process of production assembly or after-sale disassembly and assembly, the phenomenon that the MIC sealing rubber sleeve scrapes the dust screen easily occurs when the two shells are assembled up and down, and the dust screen is deviated to one side or falls off, so that the phenomena of poor audio and unstable consistency are caused.

The common solution at present is to improve the assembly method, and adopt the method of firstly loading one side of an MIC dust screen and then pressing the other side; or the assembly inclination is increased in design, and the like, and the problem cannot be completely and fundamentally solved.

Referring to fig. 1-11, the present invention provides some preferred embodiments of a dustproof structure.

As shown in fig. 4, 5, and 8, the dust-proof structure includes: the sound emitting device comprises a first shell 10, wherein a first sound emitting hole 11 is formed in the first shell 10, and a sealing element 12 is arranged on the outer side of the first sound emitting hole 11; a second housing 20 covering the first housing 10, wherein a dust screen 21 is provided on the second housing 20, and the dust screen 21 abuts against the sealing member 12; a first clamping groove 13 is formed in the first shell 10, a first clamping protrusion 22 is formed in the second shell 20, the first clamping protrusion 22 is clamped in the first clamping groove 13, and the first clamping protrusion 22 protrudes to one side, facing the sealing element 12, of the dust screen 21; and/or, set up the protruding (not shown in the figure) of second card on the first casing 10, be provided with the second draw-in groove (not shown in the figure) on the second casing 20, the protruding card of second card is gone into in the second draw-in groove, the protruding protrusion of second card extremely sealing member 12 orientation one side of dust screen 21.

The dust screen 21 abuts against the seal 12, and in order to increase the sealing performance, when the first housing 10 and the second housing 20 are assembled, the dust screen 21 and the seal 12 have an interference amount, that is, the dust screen 21 and the seal 12 are pressed against each other to form a seal. In general, in order to secure the interference amount, the dust screen 21 is protruded from the side surface of the first housing 10, but the sealing member 12 may be protruded from the second housing 20, and then the dust screen 21 and the sealing member 12 are pressed and sealed with each other after assembly.

It should be noted that, the first housing 10 and the second housing 20 are respectively provided with a snap projection structure and a snap groove structure. Because the first shell 10 covers the second shell 20, when the first shell 10 and the second shell 20 are assembled, that is, when the second shell 20 is installed in the first shell 10, due to the existence of the clamping convex structure, the clamping convex structure is located between the first shell 10 and the second shell 20, therefore, a gap exists between the first shell 10 and the second shell 20, and in the assembling process, the dust screen 21 and the sealing element 12 are not easy to interfere with each other, and the problem that the dust screen 21 falls off is also easy to occur. Of course, after the protruding structure is inserted into the slot structure, there is no space between the first housing 10 and the second housing 20, and the dust screen 21 and the sealing member 12 can still be squeezed together to form a sealing effect.

Specifically, the snap structure may be disposed on the first housing 10 and/or the second housing 20, for example, the first snap 22 is disposed on the second housing 20, and the first snap slot 13 is disposed on the first housing 10. For another example, if the first housing 10 is provided with a second protrusion, the second housing 20 is provided with a second slot. When the first housing 10 and the second housing 20 are assembled, the first snap projection 22 (and/or the second snap projection) is located between the first housing 10 and the second housing 20, and then the first housing 10 and the second housing 20 are deformed to form a space, so that the dust screen 21 and the sealing member 12 are separated from each other, and the problem that the dust screen 21 falls off due to mutual interference between the dust screen 21 and the sealing member 12 is avoided.

The first protrusion 22 protrudes to a side of the dust screen 21 facing the sealing member 12, that is, the protruding height of the first protrusion 22 is higher than that of the dust screen 21, so that, when the first protrusion 22 contacts the first housing 10 during the assembly process, the dust screen 21 does not contact the first housing 10, and then the dust screen 21 does not easily contact the sealing member 12, and the dust screen 21 does not fall off.

The protruding protrusion of second card extremely sealing member 12 orientation one side of dust screen 21, that is to say, the protruding height of second card is higher than sealing member 12, consequently, in the assembling process, the protruding with of second card during second casing 20 contacts, the sealing clip can not with second casing 20 contacts, also be difficult for with dust screen 21 contacts, is difficult to appear the problem that dust screen 21 drops.

The horizontal direction may be determined according to the first sound emitting hole 11, and the direction in which the first sound emitting hole 11 faces is the horizontal direction. The first engaging groove 13 and the sealing element 12 are staggered with each other, so that the first engaging protrusion 22 and the sealing element 12 are also staggered with each other during assembly, and the first engaging protrusion 22 does not interfere with the sealing element 12.
