Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

For example, electronic devices such as mobile phones generally include an audio module for sending or receiving audio signals, so as to implement functions of audio playing and voice communication of the electronic devices. The audio module of the electronic device in the related art needs to be provided with a dust screen to prevent external dust, impurities and the like from entering the electronic device through the audio module. However, in the assembling process of the audio module, the play of the dust screen is usually caused, and the original path of the audio propagation channel is shifted after the play of the dust screen, so that the audio effect of the audio module is affected.

Fig. 1 is a schematic cross-sectional structure diagram of an audio module according to an exemplary embodiment of the disclosure; fig. 2 is a schematic perspective view of an audio module according to an exemplary embodiment of the disclosure. As shown in fig. 1 and 2, the audio module 1 includes an audio body 11, a dust screen 12, and an elastic sealing member 13.

The predetermined area 121 may be a central area of the dust screen 12, and the elastic sealing member 13 is fitted to an edge area of the dust screen 12, so as to avoid interference of the elastic sealing member 13 with the structure and function of the sound-transmitting opening 111, and ensure stability of the elastic sealing member 13 fitted to the dust screen 12.

The sealing matching surface 131 of the elastic sealing member 13 of the audio module 1 is provided with the sealing concave portion 132, because the sealing matching surface 131 is exposed out of the audio module 1, when the audio module 1 is assembled in the electronic device, the elastic sealing member 13 is in sealing fit with other structures of the electronic device, the sealing concave portion 132 can increase the sealing area, and meanwhile, the reaction force generated by the elastic sealing member 13 in the matching process is reduced, so that the sealing effect of the audio module 1 is improved, and the influence of the reaction force of the elastic sealing member 13 on the assembling position of the dust screen 12 is reduced. The audio body 11 is provided with a limiting member 112 which is in limiting fit with the dust screen 12, so that the play of the dust screen 12 is avoided, and the preset area 121 of the dust screen 12 corresponds to the sound transmission port 111, thereby ensuring the audio effect of the audio module 1 and the electronic device.

In some embodiments, the dust screen 12 includes at least two corners, and the at least two corners are in limit fit with the position-limiting member 112. In one embodiment, as shown in fig. 2, the audio body 11 includes an inclined side surface inclined from the bottom to the top, and the sound-transmitting port 111 is provided on the inclined side surface. The dust screen 12 may include four corners: two top corners fitting to the top of the inclined sides and two bottom corners fitting to the bottom of the inclined sides. Two limiting members 112 are arranged at the top of the inclined side surface, and each limiting member 112 is in limiting fit with one top corner of the dust screen 12.

In the above embodiment, the corner is provided with the first limiting groove 122, the limiting member 112 is a limiting protrusion disposed on the audio main body 11, the limiting protrusion is in abutting fit with the first limiting groove 122, and the position of the dust screen 12 is fixed by the abutting of the limiting protrusion and the limiting groove, so as to prevent the dust screen 12 from moving. It should be noted that, the first limiting groove 122 may be an arc-shaped groove, the limiting projection is provided with an arc-shaped edge matched with the arc-shaped groove, the position of the dust screen 12 is fixed by matching the arc-shaped edge of the arc-shaped groove and the arc-shaped edge of the limiting projection, and the structure is attractive and the limiting effect is good.

The elastic sealing member 13 may be made of an elastic material such as rubber, but the disclosure is not limited thereto.

In the above embodiment, the elastic sealing element 13 may be provided with a second limiting groove 136, and the limiting element 112 is abutted and matched with the second limiting groove 136. The limiting piece 112 not only realizes the position limitation of the dust screen 12, but also realizes the position limitation of the elastic sealing piece 13, and avoids the structural interference of the elastic sealing piece 13 on the dust screen 12 and the influence on the audio effect of the audio main body 11.
