In addition, the embodiment of the present application does not limit the installation position of each sealing portion, as long as it can achieve circumferential sealing at the joint of two adjacent hole portions in the Z-axis direction. Taking the first sealing part C1 as an example, in some embodiments, as shown in FIG. 4 , the first sealing part C1 may be arranged on the periphery of the first hole part A1 and the second hole part A2 and can seal the first hole part C1 . surrounded by the part A1 and the second hole part A2; in other embodiments, as shown in Figure 5, the first sealing part C1 can also be arranged in the second hole part A2. Of course, in some other embodiments, The first sealing part C1 may also be arranged in the first hole part A1, or be located in the first hole part A1 and the second hole part A2 at the same time. In this way, the holes of the first hole part A1 and the second hole part A2 can be utilized. Installing the first sealing portion C1 in the inner space can also reduce the installation space occupied by the speaker module 8 in the Z-axis direction.

In practical applications, the speaker bracket 9 and the mainboard bracket 31 can also be integrated, that is, they can be integrally formed. In this way, the second sealing portion C2 between the speaker bracket 9 and the mainboard bracket 31 can be omitted, and the need for Z can also be reduced. Space occupied in the axial direction.

As still shown in FIG. 4 , during installation, the speaker module 8 and the speaker bracket 9 can be attached to the frame 211 in the Y-axis direction. Of course, in some other embodiments, the speaker module 8 and the speaker bracket 9 can also be arranged with a gap from the frame 211 in the Y-axis direction.

Please refer to Figures 6 and 7. Figure 6 is a schematic structural diagram of the speaker bracket, and Figure 7 is a cross-sectional view of Figure 6.

As shown in Figures 6 and 7, the speaker bracket 9 includes an annular frame 91. The annular frame 91 has a first axial end facing the middle frame 21, and the speaker module 8 can be installed on the first axial end. The aforementioned Specifically, the third sealing portion may be disposed between the speaker module 8 and the first axial end portion to achieve a sealing assembly between the first sound-emitting portion 81 and the speaker bracket 9 . Taking the orientation and positional relationship in FIGS. 3 and 4 as a reference, the first axial end may specifically refer to the lower end of the speaker bracket 9 .

In some embodiments, the first axial end may have a first sealing surface 911; the speaker module 8 has an axial direction, specifically the direction in which the first sound-emitting part 81 and the second sound-emitting part 82 are arranged oppositely. The axial direction It can be parallel to the Z-axis direction, or it can also be at an angle less than 90 degrees with the Z-axis direction, that is, the speaker module 8 can be arranged at a certain angle with respect to the Z-axis direction; the first sealing surface 911 can be aligned with the speaker module 8. The axes of group 8 can be perpendicular. In this embodiment, the axial installation end surface of the speaker module 8 and the first sealing surface 911 are basically parallel, and the third sealing portion is disposed between the first sealing surface 911 and the speaker module 8. At this time, the third sealing portion The three sealing parts can be dispensing glue or back glue.

Of course, only one of the first sealing surface 911 and the second sealing surface 912 can be selected. For example, only the first sealing surface 911 can be provided at the first axial end. Due to the elimination of the second sealing surface 912, the dimensions of the speaker bracket 9 in both the X-axis direction and the Y-axis direction can be reduced, further reducing the size of the speaker. The installation of the module 8 occupies space; alternatively, only the second sealing surface 912 can be provided at the first axial end.

Using this solution, through the variable diameter arrangement of the third hole A3, the opening area of the second hole A2 and the first hole A1 can be reduced, thereby reducing the impact on the strength of the motherboard bracket 31 and the first case 1 ; Moreover, generally speaking, the sound output area (area of the cross-section perpendicular to the axial direction) of the first sound outlet hole 100a is relatively small, and the variable diameter arrangement of the third hole portion A3 can also realize the first sealing channel. The sound transmission area (the area of the cross-section perpendicular to the sound transmission direction) gradually shrinks, which can gradually adapt to the difference between the sound transmission area and the sound emission area.

In some other solutions, the third hole part A3 may also include more hole segments, and the sound transmission area of each hole segment may gradually decrease in a stepwise manner in the direction approaching the first sound outlet 100a. Alternatively, the third hole A3 can be configured as a tapered hole, and the tapered hole can be tapered in a direction approaching the first sound hole 100a. In this way, the sound transmission area of the third hole A3 can be continuous. Zoom out.

In some optional implementations, the transition component between the speaker module 8 and the first housing 1 may not include the mainboard bracket 31 , and the speaker module 8 may be directly connected to the first housing 1 through the speaker bracket 9 Install. In this way, in the Z-axis direction, the first enclosing member only includes the first sealing part C1, the speaker bracket 9 and the third sealing part, and the first sealing channel includes the space enclosed by the first sealing part C1 and the third hole part. The space formed by the inner space of the A3 hole and the third sealing part can reduce the installation space in the Z-axis direction.

In this embodiment, the mainboard bracket 31 may be provided with escape holes for avoiding the speaker module 8 and the speaker bracket 9 . Alternatively, the mainboard bracket 31 can also be arranged at a position avoiding the speaker module 8 and the speaker bracket 9. For the convenience of description, the speaker module 8 and the speaker bracket 9 can be collectively referred to as a speaker assembly, and the mainboard bracket 31 can be located at a position away from the speaker assembly. On one side in the X-axis direction or the Y-axis direction to avoid installation interference.

In this case, the speaker module 8 may be directly docked and installed with the first housing 1, and the first enclosure The coupling member may only include the first sealing part C1, and the first sealing channel may only include a space enclosed by the first sealing part C1. In this embodiment, since the motherboard bracket 31, the speaker bracket 9, the second sealing portion C2 and the third sealing portion are omitted, the installation space occupied by the speaker module in the Z-axis direction can be reduced to the greatest extent.
