[0030] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present application, the scheme of the embodiments of the present application will be further described below. It should be noted that the embodiments of the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present application, but the embodiments of the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, not all of them.

[0032] Reference Figures 1 to 4 As shown, this embodiment provides a mobile terminal, wherein the mobile terminal may be, for example, a mobile phone, a tablet computer, a laptop computer, etc. The mobile phone may be a tablet phone, a foldable phone, etc.

[0033] Specifically, the mobile terminal includes a first shell 1 and a second shell 2 , and the first shell 1 and the second shell 2 are arranged opposite to each other along the thickness direction of the mobile terminal.

[0034] An earpiece structure 3 is provided between the first shell 1 and the second shell 2, and the earpiece structure 3 is a speaker. Exemplarily, the first shell 1 may be a front shell of a mobile terminal, and a display screen is provided on a side of the front shell away from the second shell 2.

[0035] A front sound cavity 4 for communicating with the outside of the mobile terminal is formed between the first housing 1 and the speaker. The vent hole 31 of the speaker is arranged toward the second housing 2, and a recessed portion 211 is arranged at least at a position corresponding to the vent hole 31 of the second housing 2, and the recessed portion 211 is recessed in a direction away from the speaker, so that the recessed portion 211 forms at least part of the rear sound cavity 5, and the rear sound cavity 5 is isolated from the front sound cavity 4. The thickness direction of the mobile terminal is specifically Figure 2 The ZZ direction is shown.

[0036] In other words, the speaker is directly used as the receiver structure 3 of the mobile terminal. In specific implementation, the receiver structure 3 can be located at the top of the first shell 1 and the second shell 2, for example, so that the user can answer calls, etc. For example, a bottom speaker can be set at the bottom of the first shell 1 and the second shell 2, where the bottom speaker is mainly used as amplification when playing videos, music, etc.

[0037] The mobile terminal provided in this embodiment makes the earpiece structure 3 a speaker, that is, uses the speaker as the earpiece structure 3 of the mobile terminal; forms a front sound cavity 4 for communicating with the outside of the mobile terminal between the first shell 1 and the speaker; sets the air leakage hole 31 of the speaker toward the second shell 2, and a recessed portion 211 is provided at least at a position corresponding to the air leakage hole 31 of the second shell 2, and the recessed portion 211 is recessed in a direction away from the speaker, so that the recessed portion 211 forms at least a part of the rear sound cavity 5, and the rear sound cavity 5 is isolated from the front sound cavity 4. Compared with the solution of using the earpiece as the earpiece structure, the setting of the speaker can achieve the stereo effect of the earpiece structure 3 to a certain extent, thereby improving the audio effect of the earpiece structure 3 when in use and improving the sound quality of the earpiece structure 3 to a certain extent. At the same time, since the recessed portion 211 forms at least part of the rear sound cavity 5, compared with the solution that requires moving the second shell in a direction away from the earpiece structure to separate the two and form a rear sound cavity between the second shell and the earpiece structure, this embodiment can improve the sound quality of the earpiece structure 3 through the above-mentioned arrangement while also being able to reduce the thickness of the entire machine to a certain extent, thereby facilitating the realization of a lighter and thinner development of the entire machine.

[0038] In some embodiments, reference Figure 2 As shown, the second housing 2 includes a middle frame 21 and a cover 22 connected to the side of the middle frame 21 away from the speaker. The recessed portion 211 is a through hole provided on the middle frame 21, and the through hole is provided through the middle frame 21 in the thickness direction of the mobile terminal.

[0039] That is to say, a part of the middle frame 21 is hollowed out to form a channel shape, and the air leakage hole 31 corresponds to the area, so that the formation of the rear sound cavity 5 is simple and can ensure that the rear sound cavity 5 is in a certain degree. Figure 2 The size in the Z direction ensures the volume of the rear sound cavity 5, and this arrangement makes it possible for the rear sound cavity 5 to not occupy the space of the mobile terminal. Figure 2 The thickness dimension in the Z direction is reduced, thereby effectively reducing the thickness dimension of the whole machine.

[0040] Exemplarily, the cover 22 may be, for example, a battery cover.

[0041] In some embodiments, reference Figures 2 to 4 As shown, an isolation seal 6 is further disposed between the middle frame 21 and the cover body 22. In the thickness direction of the mobile terminal, the projection of the setting area of ​​the recessed portion 211 on the isolation seal 6 is located within the area surrounded by the outer contour of the isolation seal 6.

[0042] In this way, the isolation seal 6 can, when the earpiece structure 3 is in use, to a certain extent prevent the airflow in the rear sound cavity 5 from accidentally directly impacting the cover body 22 and causing the cover body 22 to vibrate, thereby ensuring the stability of the cover body 22 to a certain extent, and this is also beneficial to ensuring the sound quality of the earpiece structure 3.

[0043] In some embodiments, the isolation seal 6 is a flexible foam. In this way, the isolation effect of the isolation seal 6 on the airflow can be improved to a certain extent through the flexible foam, and when the airflow accidentally impacts the isolation seal 6, the flexible foam can also buffer the impact to a certain extent, further improving the stability of the cover 22.

[0044] Of course, in other embodiments, the isolation seal 6 can also be a plastic part or the like.

[0045] In some embodiments, at least one side of the flexible foam corresponding to the middle frame 21 has a bonding portion, and the flexible foam is attached to the middle frame 21 through the bonding portion. In this way, the installation of the flexible foam on the middle frame 21 is simple and convenient, thereby improving the connection efficiency to a certain extent.

[0046] Exemplarily, the bonding portion may be, for example, an adhesive strip, a double-sided tape, or the like.

[0047] In some embodiments, reference Figure 2 As shown, the isolation seal 6 is sandwiched between the cover 22 and the middle frame 21. This can improve the stability of the isolation seal 6 between the cover 22 and the middle frame 21 to a certain extent, and is conducive to improving the compactness of the entire mobile terminal, thereby further reducing the thickness of the mobile terminal and realizing a lightweight design of the entire device.

[0048] In some embodiments, reference Figures 1 to 4 As shown, the middle frame 21 is provided with an indicating portion 71 for indicating the setting position of the isolation seal 6. In this way, the indicating portion 71 can provide the installation personnel with an installation guide for the isolation seal 6, thereby improving the installation efficiency of the isolation seal 6.

[0049] In some embodiments, reference Figures 1 to 4 As shown, a positioning groove 7 is provided on one side of the middle frame 21 facing the speaker, and the isolation seal 6 is located in the positioning groove 7. The size of the isolation seal 6 is adapted to the size of the positioning groove 7, and at least part of the groove wall of the positioning groove 7 is formed as an indication portion 71.

[0050] This arrangement can not only provide instructions to the installers and improve the installation efficiency, but also limit the isolation seal 6 to a certain extent through the positioning groove 7, further ensuring the accuracy and stability of the position of the isolation seal 6, making the cover body 22 more stable.

[0051] For example, when the outer contour of the isolation seal 6 fits with a portion of the groove wall of the corresponding positioning groove 7, it indicates that the installation position of the isolation seal 6 is correct.

[0052] In some embodiments, reference Figures 1 to 4 As shown, there are at least two air leakage holes 31 , which are arranged at intervals on the speaker. There are at least two recessed portions 211 , which are arranged one by one corresponding to the air leakage holes 31 .

[0053] In this way, at least two rear sound cavities 5 can be formed on the second shell 2, which is beneficial to further improve the sound quality of the earpiece structure 3 and achieve a good stereo effect.

[0054] Specifically, refer to Figures 1 to 4 As shown, in this embodiment, there are four air leakage holes 31 and four corresponding recessed portions 211 .

[0055] In some embodiments, reference Figures 1 to 3 As shown, along the thickness direction of the mobile terminal, the projection of the air leakage hole 31 on the second housing 2 is located in the recessed portion 211. This can ensure the size and volume of the rear sound cavity 5 to a certain extent, so that the sound quality and sound effect of the earpiece structure 3 can be further improved.
