1 is an exploded perspective view of a microphone assembly and a mobile phone casing according to a preferred embodiment of the present invention; and FIG. 2 is a perspective exploded view of another embodiment of the microphone assembly and the mobile phone casing according to a preferred embodiment of the present invention; Figure 3 is a cross-sectional view of the microphone assembly of the preferred embodiment of the present invention assembled to a mobile phone housing.

Referring to Figures 1 and 2, the present invention discloses a microphone assembly 10, which is illustrated in the preferred embodiment of the present invention by its use in a mobile phone.

The mobile phone includes a housing 30 having a bottom portion 31. A receiving groove 32 is recessed in the bottom portion 31 adjacent to one end of the housing 30. The accommodating groove 32 has two opposite side walls 322. One of the side walls 322 defines two slots 324, and the other side wall 322 defines two receiving slots 326.

The microphone assembly 10 of the preferred embodiment of the present invention includes a limiting member 12 and a microphone body 14. The limiting member 12 is made of a material having elasticity, and the limiting member 12 of the preferred embodiment of the present invention is made of a rubber material. The limiting member 12 includes a connecting arm 122 and two protruding blocks 124. The two protruding blocks 124 are vertically extended from two ends of the connecting arm 122, and are enclosed by the protruding block 124 and the connecting arm 122. A limit port 126. The limiting port 126 has two opposite side walls 1262, and a stopping portion 1264 is respectively protruded from the two side walls 1262. Two latching portions 1222 are protruded from the side of the connecting arm 122 away from the two protrusions 124. The latching portions 1222 are respectively corresponding to the receiving slots 326 of the side wall 322 of the receiving slot 32, and can be latched. Yusho The storage tank 326 is described. Each of the protrusions 124 is disposed on a side of the connecting arm 122, and a buckle 1242 is respectively disposed on the side of the connecting arm 122. The buckle 1242 is respectively corresponding to the slot 324 of the other side wall 322 of the receiving slot 32, and can be latched. In the slot 324.

The microphone body 14 has a rectangular plate shape, and a hook 16 is respectively protruded from the opposite end portions. Each of the hooks 16 has an engaging surface 162 and a matching surface 162 at the free end. The opposite slope 164. The hook 16 has elasticity, and when the external force abuts against the inclined surface 164, the hook 16 can be elastically deformed. The hook 16 is restored to the initial state after the external force is removed.

As shown in FIG. 3 , the limiting member 12 is engaged with the receiving groove 326 and the slot 324 by the engaging portion 1222 and the buckle 1242 to fix the limiting member 12 to the receiving slot. In the 32, the limiting member 12 and the side wall 322 of the receiving groove 32 together define a groove (not shown). The microphone body 14 is then aligned with the recess and the microphone body 14 is lowered. The two stopping portions 1264 respectively abut against the inclined surface 164 of the hook 16 and elastically deform the hook 16 and push each hook 16 below the corresponding stopping portion 1264. At this time, the hook 16 returns to the initial state under the elastic restoring force, and the engaging surface 162 and the stopping portion 1264 abut each other, thereby fixing the microphone body 14 in the groove. .

When the speaker body 14 is disassembled, a force can be applied to the limiting member 12. Since the limiting member 12 has elasticity, the locking portion 1222 and the buckle 1242 can be disengaged from the receiving groove 326 and the slot. 324 limits it so that the limiting member 12 is taken out of the accommodating groove 32. The hook 16 of the microphone body 14 is disengaged from the stop portion 1264, so that the microphone body 14 can be directly from the accommodating slot 32. take out.

The microphone assembly 10 adopts a split structure, and the microphone body 14 can be easily replaced. If the structure and size of the replaced microphone body 14 are changed, it is only necessary to change the size of the limiting member 12 to fix the microphone body 14 without changing the structure of the interior of the housing 30, thereby improving the housing. The reliability of the body 30.

It can be understood that the limiting member 12 can also be a four-sided closed frame structure having a notch, and the microphone body can be fixed in the notch.

It can be understood that the holding portion 1222 and the buckle 1242 protruding from the limiting member 12 have the same structure and can be regarded as a fastening component together, and the receiving groove 326 can also be regarded as the slot 324.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
