In addition, the embodiment of the present application is not limited to the installation position of each sealing portion, as long as it can achieve circumferential sealing at the junction of two adjacent hole portions in the Z-axis direction. Taking the first sealing portion C1 as an example, in some embodiments, as shown in fig. 4, the first sealing portion C1 may be disposed at the outer periphery of the first hole portion A1 and the second hole portion A2, and may surround the first hole portion A1 and the second hole portion A2; in other embodiments, as shown in fig. 5, the first sealing portion C1 may be disposed in the second hole portion A2, and of course, in other embodiments, the first sealing portion C1 may be disposed in the first hole portion A1, or may be located in both the first hole portion A1 and the second hole portion A2, so that the first sealing portion C1 may be installed by using the space in the holes of the first hole portion A1 and the second hole portion A2, and the installation space of the speaker module 8 in the Z-axis direction may be reduced.

In practical application, the speaker support 9 and the main board support 31 may be integrally formed, so that the second sealing portion C2 between the speaker support 9 and the main board support 31 may be omitted, and space occupation in the Z-axis direction may be reduced.

As also shown in fig. 4, the speaker module 8 and the speaker bracket 9 may be attached to the frame 211 in the Y-axis direction when mounted. Of course, in other embodiments, the speaker module 8 and the speaker bracket 9 may be disposed at a distance from the frame 211 in the Y-axis direction.

Referring to fig. 6 and 7, fig. 6 is a schematic structural view of a speaker bracket, and fig. 7 is a sectional view of fig. 6.

As shown in fig. 6 and 7, the speaker bracket 9 includes an annular rim 91, the annular rim 91 having a first axial end portion facing the middle frame 21, to which the speaker module 8 may be mounted, and the aforementioned third sealing portion may be specifically disposed between the speaker module 8 and the first axial end portion for achieving a sealing fit between the first sound emitting portion 81 and the speaker bracket 9. With reference to the azimuth and positional relationship in fig. 3 and 4, the first axial end portion may specifically be referred to as a lower end portion 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, a direction in which the first sound generating portion 81 and the second sound generating portion 82 are oppositely disposed, and the axial direction may be parallel to the Z-axis direction, or may also form an included angle smaller than 90 degrees with the Z-axis direction, that is, the speaker module 8 may be disposed with a certain angle inclined with respect to the Z-axis direction; the first sealing surface 911 may be perpendicular to the axial direction of the speaker module 8. In this embodiment, the axial mounting end surface of the speaker module 8 and the first sealing surface 911 are substantially parallel, and the third sealing portion is disposed between the first sealing surface 911 and the speaker module 8, and at this time, the third sealing portion may be dispensing or back-coating.

In other embodiments, the first axial end may have a second sealing surface 912, the second sealing surface 912 may be disposed at an angle to the axial direction of the speaker module 8, and the angle may be less than 90 degrees. In the assembled state, the second sealing surface 912 and the outer peripheral wall surface of the speaker module 8 may be enclosed to form a sealing groove, and the third sealing portion may be disposed in the sealing groove, and at this time, the third sealing portion may be dispensing.

The second sealing surface 912 may be a flat surface, or may be a conical surface, a spherical surface, or the like.

In practical application, the first axial end portion may include the first sealing surface 911 and the second sealing surface 912 at the same time, at this time, two seals may be formed between the speaker module 8 and the speaker bracket 9, so that the sealing effect is better. Of course, only one of the first sealing surface 911 and the second sealing surface 912 may be selected. For example, the first axial end may be provided with only the first sealing surface 911, and the size of the speaker bracket 9 in the X-axis direction and the Y-axis direction may be reduced due to the elimination of the second sealing surface 912, which may further reduce the installation space of the speaker module 8; alternatively, only the second sealing surface 912 may be provided at the first axial end portion, and at this time, the space in the hole of the third hole portion A3 may be relatively large due to the elimination of the first sealing surface 911, and a sealing portion may be omitted to reduce the cost.

With continued reference to fig. 7, an annular bottom plate 92 is disposed at an end of the annular frame 91 away from the first axial end, and the annular bottom plate 92 can change a cross-sectional area of the third hole portion A3 perpendicular to the axial direction, so as to design the third hole portion A3 as a stepped hole, where the third hole portion A3 includes a small neck hole section a32 and a large neck hole section a31 that are connected, and the small neck hole section a32 is communicated with the second hole portion A2.

By adopting the scheme, the aperture areas of the second hole part A2 and the first hole part A1 can be reduced by the reducing arrangement of the third hole part A3, and the influence on the strength of the main board bracket 31 and the first shell 1 can be further reduced; in general, the sound output area (the area of the cross section perpendicular to the axial direction) of the first sound output hole 100a is relatively small, and the reducing arrangement of the third hole portion A3 can also achieve gradual reduction of the sound transmission area (the area of the cross section perpendicular to the sound transmission direction) of the first seal channel, so that the difference between the sound output area and the sound output area can be gradually adapted.

In other embodiments, the third hole portion A3 may further include more hole segments, and the sound transmission area of each hole segment may be gradually reduced in a direction approaching the first sound outlet 100 a. Alternatively, the third hole portion A3 may be provided as a tapered hole which may be tapered in a direction approaching the first sound outlet hole 100a, so that the sound transmission area of the third hole portion A3 may exhibit continuous reduction.

In some alternative embodiments, the transition part between the speaker module 8 and the first housing 1 may not include the motherboard bracket 31, and the speaker module 8 may be directly butt-mounted with the first housing 1 through the speaker bracket 9. Thus, in the Z-axis direction, the first enclosing member includes only the first sealing portion C1, the speaker bracket 9, and the third sealing portion, and the first sealing passage includes the space formed by enclosing the first sealing portion C1, the in-hole space of the third hole portion A3, and the space formed by enclosing the third sealing portion, so that the installation occupation space in the Z-axis direction can be reduced.

In this embodiment, the main board support 31 may be provided with a avoidance hole for avoiding the speaker module 8 and the speaker support 9. Alternatively, the main board support 31 may be disposed at a position avoiding the speaker module 8 and the speaker support 9, and for convenience of description, the speaker module 8 and the speaker support 9 may be collectively referred to as a speaker assembly, and the main board support 31 may be disposed at one side of the speaker assembly in the X-axis direction or the Y-axis direction, so as to avoid mounting interference.

In some alternative embodiments, no transition part may be disposed between the speaker module 8 and the first housing 1, where the speaker module 8 may be directly butt-mounted with the first housing 1, the first enclosing member may only include the first sealing portion C1, and the first sealing channel may only include a space enclosed by the first sealing portion C1. In this embodiment, since the main board holder 31, the speaker holder 9, the second sealing portion C2, and the third sealing portion are omitted, the installation space of the speaker module in the Z-axis direction can be reduced to the greatest extent.
