The position that the frame of protective housing 10 corresponds cell-phone loudspeaker is equipped with through-hole 12, and in the embodiment shown, through-hole 12 sets up to two, and two through-holes 12 all set up in the frame bottom of protective housing 10, nevertheless the utility model discloses do not injecing this, in other embodiments, through-hole 12 also can set up to other quantity. The protective shell 10 further comprises two dustproof devices 14, and correspondingly, two dustproof devices 14 are arranged, and one dustproof device 14 is detachably mounted in each through hole 12, so that the dustproof devices 14 can be detached from the protective shell 10 for cleaning. Since the structure of each through hole 12 and the dust-proof device 14 is the same, only one through hole 12 and dust-proof device 14 will be described in detail below.

The dust-proof means 14 is installed in the through-hole 12 such that external dust passes through the dust-proof means 14 before passing through the protective case 10. More specifically, the dust-proof device 14 includes a base housing 16 with an opening at one end and a dust-proof portion 18 disposed on the base housing 16, the base housing 16 has a cavity therein, and the dust-proof portion 18 has a dust-proof function. In the illustrated embodiment, the end wall of the base shell 16 opposite to the open end thereof is provided with a plurality of dust-proof holes having a dust-proof adsorption function, and the plurality of dust-proof holes are arranged at intervals in the central region of the end wall of the base shell 16 to form the dust-proof portion 18.

In other embodiments, the dust-proof device 14 may be configured such that a mounting hole is formed on the end wall of the base shell 16, and the dust-proof portion 18 is a dust-proof net having a plurality of dust-proof holes, the dust-proof net being detachably mounted in the mounting hole, and the dust-proof net and the mounting hole being connected by, for example, a snap-fit connection.

The opening end of the base shell 16 extends outwards to form a protruding portion 20, a groove 22 is formed in the periphery of the through hole 12 on the inner surface of the bottom of the frame of the protective shell 10, the dustproof device 14 is clamped in the groove 22 through the protruding portion 20 to be detachably connected into the through hole 12, the dustproof portion 18 corresponds to the through hole 12 in position, sound played by the mobile phone can be transmitted to the outside from the dustproof portion 18 through the through hole 12, or the outside sound can be received by a loudspeaker of the mobile phone from the through hole 12 through the dustproof portion 18, and therefore the dustproof device 14 can play a dustproof role under the condition that the using effect of the through hole 12 is not affected.

In some embodiments, to further enhance the connection stability of the dust-proof device 14, an adhesive groove may be disposed in the groove 22, and the adhesive groove is used for accommodating an adhesive, such as a liquid adhesive or a solid adhesive, and an adhesive layer, etc., and the protruding portion 20 is adhered to the adhesive in the adhesive groove when engaged in the groove 22. In other embodiments, an adhesive groove may be provided on the protrusion 20, for example, an adhesive groove may be provided on an inner wall surface of the protrusion 20, or an adhesive groove may be provided in the groove 22 and on the protrusion 20 at the same time.

In the illustrated embodiment, the boss 20 is annular extending outwardly along the open end of the base shell 16 along an end surface thereof, and correspondingly, the groove 22 is annular formed recessed inwardly along the periphery of the through-hole 12. When the mobile phone is installed, the mobile phone in the protective shell 10 needs to be taken out, the base shell 16 is installed in the protective shell 10, the whole protruding portion 20 is clamped in the groove 22, the outer side wall of the base shell 16 abuts against the inner side wall of the through hole 12, and therefore the dustproof device 14 is installed and fixed. When the mobile phone needs to be detached, the mobile phone is taken out, and force is applied from the outside of the protective shell 10 to push the dustproof device 14 inwards, so that the protruding part 20 is separated from the groove 22, and the detachment is realized.

After dust keeper 14 installed in through-hole 12, dust keeper 14's surface, the surface that also is the end wall of base shell 16 and the surface parallel and level of protective housing 10 increase the whole pleasing to the eye degree of protective housing 10, and increase the user and use and feel, avoid knocking hands. In other embodiments, the outer surface of the end wall of the base shell 16 may be configured to protrude slightly beyond the outer surface of the protective shell 10, or the outer surface of the end wall of the base shell 16 may be located within the outer surface of the protective shell 10.
