Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] With the advancement of technology, mobile phones have become increasingly feature-rich. Waterproofing is one of the key performance characteristics of mobile phones. Since the speaker in a mobile phone is connected to the outside world and is a major pathway for liquid ingress, it is necessary to seal the area between the speaker and the main frame of the phone.

[0003] To improve waterproofing, a silicone seal is installed between the speaker and the mid-frame. During the process of installing the speaker into the mid-frame, the speaker container scrapes against the silicone seal, causing it to deform. When the speaker is installed in place, the deformed silicone seal will cause poor sealing between the speaker and the mid-frame, failing to meet the waterproofing requirements. Utility Model Content

[0004] This application aims to provide an electronic device that at least solves the problem in the related art where deformation of the silicone seal during speaker installation leads to poor sealing between the speaker and the mid-frame.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides an electronic device, including:

[0007] The frame has a mounting cavity.

[0008] A sealing assembly is located inside the mounting cavity. The sealing assembly includes an elastic part, a sealing part, and a first protrusion. The elastic part is connected to the frame, the sealing part is located on the side of the elastic part away from the frame, and the first protrusion is disposed on both sides of the sealing part.

[0009] The sound-generating component is located inside the mounting cavity. The side of the sound-generating component facing the sealing component has a clearance groove. When the sound-generating component is moved to the mounting position, the sound-generating component fits into the sealing part, and the first protrusion extends into the clearance groove. Before the sound-generating component is moved to the mounting position, the sound-generating component is used to push the first protrusion to compress the elastic part.

[0010] In the embodiments of this application, the first protrusion is disposed on the sealing portion. During the installation of the sound-generating component into the mounting cavity, before the sound-generating component moves to the mounting position (i.e., before the sound-generating component is fully installed), the sound-generating component contacts the first protrusion and can push the first protrusion. At this time, the elastic portion is compressed, the sealing portion approaches the frame, and the sealing portion moves away from the sound-generating component, thereby allowing the sealing portion to avoid the sound-generating component. During the installation of the sound-generating component into the mounting cavity, interference between the sound-generating component and the sealing portion is less likely to occur, and the sound-generating component is less likely to scrape against the sealing portion, thereby preventing deformation of the sealing portion.

[0011] When the sound-generating component is installed in place, the first protrusion extends into the recessed area on the sound-generating component. At this point, the sound-generating component no longer pushes the first protrusion, and the elastic part returns to its original position under the action of elasticity. The elastic part can push the sealing part towards the sound-generating component, so that the sealing part fits tightly against the sound-generating component. Since the sound-generating component is not easily deformed during installation, the sealing part can fit tightly against the sound-generating component when it is installed in place, avoiding the problem of poor sealing caused by deformation of the sealing part, which is conducive to meeting the waterproof rating requirements.

[0033] The following is combined with Figures 1-14 This application describes an electronic device according to an embodiment of the present application.

[0034] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an electronic device 100 according to some embodiments of this application includes: a frame 110, a sealing assembly 120, and a sound-generating assembly 130. The frame 110 has a mounting cavity 111. The sealing assembly 120 is located within the mounting cavity 111. The sealing assembly 120 includes an elastic portion 121, a sealing portion 122, and a first protrusion 123. The elastic portion 121 is connected to the frame 110, the sealing portion 122 is located on the side of the elastic portion 121 away from the frame 110, and the first protrusion 123 is disposed on both sides of the sealing portion 122. The sound-generating component 130 is located in the mounting cavity 111 and fits against the sealing part 122. The sound-generating component 130 has a clearance groove 131 on the side facing the sealing component 120. When the sound-generating component 130 is moved to the mounting position, the first protrusion 123 extends into the clearance groove 131. Before the sound-generating component 130 is moved to the mounting position, the sound-generating component 130 pushes the first protrusion 123 to compress the elastic part 121.

[0035] The frame 110 is provided with a mounting cavity 111. The sealing component 120 and the sound-generating component 130 can be installed into the mounting cavity 111. When the sound-generating component 130 is moved to the mounting position, the sound-generating component 130 is installed in place. At this time, the sealing component 120 is located between the sound-generating component 130 and the frame 110. The sealing component 120 seals the space between the sound-generating component 130 and the frame 110 to prevent external liquid from entering the frame 110 through the gap between the sound-generating component 130 and the frame 110.

[0036] The sealing assembly 120 includes an elastic portion 121, a sealing portion 122, and a first protrusion 123. The elastic portion 121 is fixed to the frame 110, and the sealing portion 122 is located on the side of the elastic portion 121 facing away from the frame 110. When the sound-generating assembly 130 is installed in place, the sealing portion 122 fits against the sound-generating assembly 130. A relatively soft material can be selected to make the sealing portion 122. The sealing portion 122 fits tightly against the sound-generating assembly 130, thereby ensuring a sealing effect. The elastic portion 121 between the sealing portion 122 and the frame 110 is elastic. When the elastic portion 121 is compressed, the sealing portion 122 moves towards the frame 110, and the distance between the sealing portion 122 and the frame 110 decreases.

[0037] The first protrusion 123 is disposed on the sealing portion 122. During the installation of the sound-generating component 130 into the mounting cavity 111, before the sound-generating component 130 moves to the mounting position (i.e., before the sound-generating component 130 is fully installed), the sound-generating component 130 contacts the first protrusion 123 and can push the first protrusion 123. At this time, the elastic portion 121 is compressed, and the sealing portion 122 approaches the frame 110. The sealing portion 122 moves away from the sound-generating component 130, thereby allowing the sealing portion 122 to avoid the sound-generating component 130. During the installation of the sound-generating component 130 into the mounting cavity 111, interference between the sound-generating component 130 and the sealing portion 122 is unlikely, and the sound-generating component 130 is unlikely to scrape against the sealing portion 122, thereby preventing deformation of the sealing portion 122.

[0038] When the sound-generating component 130 is installed in place, the first protrusion 123 extends into the recessed groove 131 on the sound-generating component 130. At this time, the sound-generating component 130 no longer pushes the first protrusion 123, and the elastic part 121 returns to its original position under the action of elastic force. The elastic part 121 can push the sealing part 122 toward the sound-generating component 130, so that the sealing part 122 fits against the sound-generating component 130. Since the sound-generating component 130 is not easily deformed during installation, the sealing part 122 can fit tightly against the sound-generating component 130 when the sound-generating component 130 is installed in place, avoiding the problem of poor sealing caused by the deformation of the sealing part 122, which is conducive to meeting the waterproof rating requirements.

[0039] For example, the sound-generating component 130 in this embodiment can be a BOX (box) for sound generation. In order to meet the IP68 waterproof rating, the side of the sealing part 122 facing the sound-generating component 130 is designed with a lip-shaped structure, which can be referred to as the silicone ear 128.

[0040] Furthermore, by avoiding the sound-generating component 130 by the sealing part 122, the sound-generating component 130 can be vertically installed into the mounting cavity 111. This not only improves the problem of scraping the sealing part 122, but also increases the volume of the sound cavity of the sound-generating component 130 (the smaller the angle between the sound-generating hole 138 of the sound-generating component 130 and the vertical direction, the larger the volume of the sound-generating component 130 within the effective width).

[0041] The sealing part 122 is provided with a first protrusion 123 on both sides, so that the two sides of the sealing part 122 are balanced by force, avoiding the problem of deflection of the sealing assembly 120 during installation and ensuring the installation stability of the sealing assembly 120.

[0042] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, the recessed groove 131 includes a groove sidewall 132, a first side of the first protrusion 123 faces the groove sidewall 132, the first protrusion 123 includes an abutment surface 1231, and when the sound-generating assembly 130 is moved to the mounting position, the abutment surface 1231 of the first protrusion 123 faces the groove sidewall 132. Before the sound-generating assembly 130 is installed into the frame 110, along a direction perpendicular to the sidewall 136 ( Figure 5 (The arrow at A1 points to) the maximum interference between the first protrusion 123 and the sound-generating component 130 is greater than the maximum interference between the sealing part 122 and the sound-generating component 130.

[0043] With the sound-generating component 130 installed, the first protrusion 123 extends into the clearance groove 131. The clearance groove 131 has a groove sidewall 132. The abutment surface 1231 of the first protrusion 123 faces the groove sidewall 132. Before the sound-generating component 130 is installed, the maximum interference between the first protrusion 123 and the sound-generating component 130 is... Figure 5 D1 in the middle.

[0044] Before the sound-generating assembly 130 is installed, there is also interference between the sound-generating assembly 130 and the sealing part 122. The maximum interference between the sealing part 122 and the sound-generating assembly 130 is... Figure 6 D2 in the middle.

[0045] D1 and D2 satisfy the following relationship: D1 > D2, that is, the interference between the sound-generating component 130 and the first protrusion 123 is greater than the interference between the sound-generating component 130 and the sealing part 122. During the installation of the sound-generating component 130 into the mounting cavity 111, the sound-generating component 130 needs to push the first protrusion 123. The distance that the sound-generating component 130 pushes the first protrusion 123 is D1. The distance that the sealing part 122 moves under the drive of the first protrusion 123 is D1. The compression of the elastic part 121 is D1.

[0046] Since D1 > D2, when the distance that the first protrusion 123 is pushed is D1, the distance that the sealing part 122 moves is greater than the amount of interference between the sound-generating component 130 and the sealing part 122. There is a gap between the sound-generating component 130 and the sealing part 122. In this case, as the sound-generating component 130 moves into the mounting cavity 111, the sound-generating component 130 will not rub against the sealing part 122, thereby avoiding deformation of the sealing part 122 caused by the sound-generating component 130. When the sound-generating component 130 is installed in place, it ensures good fit between the sealing part 122 and the sound-generating component 130, thereby ensuring the sealing effect between the two.

[0047] The interference between the first protrusion 123 and the sound-generating component 130 refers to the fact that when the sound-generating component 130 is installed, the first protrusion 123 will obstruct the installation process of the sound-generating component 130, and the first protrusion 123 needs to move a certain distance to avoid the sound-generating component 130. The distance that the first protrusion 123 moves is the interference between the first protrusion 123 and the sound-generating component 130.

[0048] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, in some embodiments, optionally, the sound-generating assembly 130 includes a sound-generating element 133 and a second protrusion 134. The second protrusion 134 is disposed on the sound-generating element 133. Before the sound-generating assembly 130 is moved to the mounting position, the second protrusion 134 is used to push the first protrusion 123 to compress the elastic part 121.

[0049] A second protrusion 134 is provided on the sound-generating assembly 130, and the second protrusion 134 is located on the side of the sound-generating assembly 130 facing the sealing assembly 120. During the installation of the sound-generating assembly 130 into the mounting cavity 111, the second protrusion 134 pushes the first protrusion 123, and the first protrusion 123 drives the sealing part 122 to move away from the sound-generating assembly 130. When the first protrusion 123 passes the second protrusion 134, the first protrusion 123 extends into the clearance groove 131.

[0050] By providing a second protrusion 134 on the sound-generating assembly 130, the size of the first protrusion 123 in the compression direction of the elastic part 121 can be reduced, thereby correspondingly reducing the size of the clearance groove 131 and avoiding the situation where the size of the clearance groove 131 is too large and affects the internal structural layout of the sound-generating assembly 130.

[0051] This embodiment proposes a design scheme to improve the effect of scraping the silicone ears 128 during assembly. When assembling the BOX vertically, the second protrusion 134 and the first protrusion 123 on the BOX cooperate to push open the sealing part 122, thereby preventing the side wall 136 of the BOX from scraping the silicone ears 128.

[0052] The sound-generating component 130 has a second protrusion 134 and a clearance groove 131 on the left and right sides of the sound-generating hole 138. When the sound-generating component 130 is assembled, the second protrusion 134 first contacts the first protrusion 123 to open the sealing part 122. When it is assembled in place, the first protrusion 123 and the clearance groove 131 cooperate.

[0053] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the sealing portion 122 includes a bracket 124 and a sealing element 125. The bracket 124 is connected to the elastic portion 121, and a first protrusion 123 is disposed on both sides of the bracket 124. The bracket 124 is provided with a mounting surface 129. The sealing element 125 is connected to the mounting surface 129, and the sealing element 125 and the elastic portion 121 are located on opposite sides of the bracket 124. The first protrusion 123 and the sealing element 125 protrude from the mounting surface 129.

[0054] The bracket 124 is connected to the elastic part 121, and the seal 125 is installed on the bracket 124. The bracket 124 supports the seal 125 to prevent the seal 125 from deforming when it is in contact with the sound-generating component 130, thus ensuring the sealing effect between the seal 125 and the sound-generating component 130.

[0055] The mounting surface 129 of the bracket 124 faces the sound-generating assembly 130. The seal 125 is mounted on the mounting surface 129, so the seal 125 protrudes from the mounting surface 129, ensuring that the seal 125 can fit tightly against the sound-generating assembly 130. The first protrusion 123 is provided on both sides of the bracket 124, and the first protrusion 123 also protrudes from the mounting surface 129, ensuring that the first protrusion 123 and the second protrusion 134 can be stably engaged.

[0056] In this embodiment, the height H2 of the seal 125 protruding from the mounting surface 129 is less than or equal to the height H1 of the first protrusion 123 protruding from the mounting surface 129. Therefore, the first protrusion 123 does not protrude from the seal 125.

[0057] The first protrusion 123 protrudes from the mounting surface 129 in a relatively short length. Under stress, the first protrusion 123 is less likely to detach from the bracket 124, thereby ensuring the connection stability between the first protrusion 123 and the bracket 124.

[0058] The seal 125 is bonded to the bracket 124 with adhesive. An elastic part 121 is attached to the bottom of the bracket 124. The elastic part 121 can be a component with elasticity such as foam, spring, or rubber. The elastic part 121 is bonded to the main body (frame 110) at the position corresponding to the sound outlet 113 with double-sided adhesive 126. First protrusions 123 are designed at both ends of the bracket 124.

[0059] The sealing assembly 120 is assembled on the frame 110 in the following positions: Figure 9 As shown, the first protrusion 123 and the clearance groove 131 fit perfectly together. Since the bottom of the bracket 124 is attached to the elastic part 121, during the assembly of the sound-generating assembly 130, the second protrusion 134 and the first protrusion 123 cooperate to push open the bracket 124, thereby causing the seal 125 to retract, preventing the seal 125 from contacting the side wall 136 on the sound-generating assembly 130 and causing the seal 125 to flip over. After assembly, the first protrusion 123 and the second protrusion 134 are misaligned, and the bracket 124 retracts under the pushing force of the elastic part 121, completing the pre-compression of the seal 125.

[0060] Combination Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, in some embodiments, optionally, the sound-generating component 133 includes a sidewall 136, a second protrusion 134 protruding from the sidewall 136, the second protrusion 134 including a pressing surface 1341, and the sealing portion 122 including a sealing side 1221. When the second protrusion 134 pushes the first protrusion 123, the pressing surface 1341 is in contact with the abutment surface 1231. When the sound-generating component 130 is moved to the mounting position, the sealing side 1221 is in contact with the sidewall 136. Before the sound-generating component 130 is installed into the frame, the maximum distance between the abutment surface 1231 and the pressing surface 1341 in a direction perpendicular to the sidewall 136 is greater than the maximum distance between the sealing side 1221 and the sidewall 136.

[0061] Before the sound-generating component 130 is installed, the interference between the first protrusion 123 and the second protrusion 134 is D1, and the interference between the sealing part 122 and the side wall 136 is D2. Since D1 is greater than D2, the sound-generating component 130 will not touch the sealing part 122 during the installation process, thus preventing the sealing part 122 from being scratched and deformed.

[0062] During the installation of the sound-generating component 130 into the mounting cavity 111, the second protrusion 134 pushes the first protrusion 123. After the first protrusion 123 passes the second protrusion 134, it moves a certain distance toward the sound-generating component 130. D3 is the distance the first protrusion 123 moves after it leaves the second protrusion 134. D3 is less than or equal to D1. When the depth of the clearance groove 131 is large, the clearance groove 131 avoids the first protrusion 123, so that the distance the first protrusion 123 can move after it leaves the second protrusion 134 is equal to D1. If the depth of the clearance groove 131 is small, the distance the first protrusion 123 moves after it leaves the second protrusion 134 is not D1 before it contacts the groove sidewall 132 of the clearance groove 131, so that the distance the first protrusion 123 can move after it leaves the second protrusion 134 is less than D1.

[0063] The sound-generating component 130 is provided with a side wall 136, a second protrusion 134 protrudes from the side wall 136, and a clearance groove 131 is provided on the side wall 136. When the sound-generating component 130 is installed in place, the seal 125 is attached to the side wall 136.

[0064] During the process of moving the sound-generating component 130 into the mounting cavity 111, the sound-generating component 130 is less likely to scrape against the seal 125. At this time, a gap is left between the seal 125 and the side wall 136.

[0065] It should be noted that before the sound-generating component 130 is installed, there is an interference between the first protrusion 123 and the second protrusion 134, and there is an interference between the sealing part 122 and the sound-generating component 130. In the installation direction of the sound-generating component 130, the sealing part 122 and the second protrusion 134 are misaligned. That is, during the installation of the sound-generating component 130, the second protrusion 134 will not contact the sealing part 122.

[0066] Combination Figure 6 and Figure 9 As shown, before installing the sound-generating assembly 130, the interference between the first protrusion 123 and the second protrusion 134 is D1, and the interference between the sidewall 136 and the sealing portion 122 of the sound-generating assembly 130 is D2, and the design satisfies D1 > D2. Combined with... Figure 5 and Figure 6 As shown, the first protrusion 123 and the second protrusion 134 contact each other first to prevent the sealing part 122 from being scraped over by the sound-generating assembly 130. Combined Figure 7 and Figure 8As shown, the sound-generating assembly 130 continues to assemble downwards. The first protrusion 123 and the second protrusion 134 cooperate, thereby pushing the bracket 124. The bracket 124 causes the seal 125 to retract (the elastic part 121 at the bottom of the bracket 124 is compressed), and the compression amount of the elastic part 121 at the bottom of the bracket 124 is D1. At this time, the distance D5 between the side wall 136 of the sound-generating assembly 130 and the seal 125 is D1-D2, because the design satisfies D1>D2. Therefore, the side wall 136 and the seal 125 are in clearance fit, and the seal 125 will not be overturned when the sound-generating assembly 130 is pressed down for assembly.

[0067] Combination Figure 9 and Figure 10 As shown, after assembly, the first protrusion 123 and the clearance groove 131 are interlocked, the elastic part 121 rebounds, and the sealing element 125 and the side wall 136 are sealed.

[0068] Combination Figure 1 and Figure 5 As shown, in some embodiments, optionally, the mounting cavity 111 has a cavity bottom wall 112, and the sound-generating assembly 130 has a chamfer 135 on one side adjacent to the cavity bottom wall 112. Before the sound-generating assembly 130 is installed into the frame, the chamfer 135 is used to avoid the sealing part 122.

[0069] The chamfer 135 is used to avoid the sealing part 122. When installing the sound-generating component 130, the bottom corner of the sound-generating component 130 is prevented from scraping the sealing part 122 and the sealing part 122 is prevented from being scraped over.

[0070] In one possible application, a guide slope 127 is machined on the first protrusion 123. During the process of moving the sound-generating component 130 into the mounting cavity 111, the sound-generating component 130 slides along the guide slope 127 on the first protrusion 123, thereby gradually pushing the first protrusion 123. In this process, it is not necessary to manually push the sealing component 120 away from the sound-generating component 130. The sealing component 120 can be automatically pushed, which improves the installation convenience of the sound-generating component 130.

[0071] Combination Figure 3 and Figure 5 As shown, in some embodiments, along the mounting direction of the sound-generating assembly 130 ( Figure 5 (As indicated by the arrow at A2 in the middle), the sound-generating component 130 is provided with a clearance groove 131 and a second protrusion 134 in sequence.

[0072] In the mounting direction of the sound-generating assembly 130, a clearance groove 131 and a second protrusion 134 are sequentially provided on the sound-generating assembly 130. Therefore, the second protrusion 134 is closer to the bottom of the mounting cavity 111. When the sound-generating assembly 130 is installed, since the second protrusion 134 is closer to the bottom of the mounting cavity 111, it can be ensured that when the second protrusion 134 contacts the first protrusion 123, the sound-generating element 133 does not contact the sealing part 122, thereby avoiding scraping the sealing part 122.

[0073] The mounting cavity 111 has a cavity bottom wall 112. When the sound-generating component 130 is installed in place, the distance between the second protrusion 134 and the cavity bottom wall 112 is less than the distance between the clearance groove 131 and the cavity bottom wall 112.

[0074] Combination Figure 1 , Figure 2 , Figure 13 and Figure 14 As shown, in some embodiments, optionally, the sound-generating assembly 130 includes a sidewall 136, and the sealing portion 122 includes a sealing side 1221. When the sound-generating assembly 130 is in the mounting position, the sidewall 136 is in contact with the sealing side 1221. The sealing portion 122 includes a bracket 124 and a seal 125. The bracket 124 is connected to the elastic portion 121. A first protrusion 123 is disposed on both sides of the bracket 124, and the bracket 124 is provided with a mounting surface 129. The seal 125 is connected to the mounting surface 129. The seal 125 and the elastic portion 121 are located on opposite sides of the bracket 124. The height of the first protrusion 123 protruding from the mounting surface 129 is greater than the height of the seal 125 protruding from the mounting surface 129. Before the sound-generating assembly 130 moves to the mounting position, the sidewall 136 is used to push the first protrusion 123 to compress the elastic portion 121.

[0075] The sound-generating component 130 has a side wall 136, and a clearance groove 131 is provided on the side wall 136. When the sound-generating component 130 is installed in place, the seal 125 is attached to the side wall 136.

[0076] During the installation of the sound-generating component 130 into the mounting cavity 111, the side wall 136 pushes the first protrusion 123, and the first protrusion 123 drives the sealing part 122 to move away from the sound-generating component 130. When the clearance groove 131 is directly opposite the first protrusion 123, the first protrusion 123 extends into the clearance groove 131.

[0077] The bracket 124 is connected to the elastic part 121, and the seal 125 is installed on the bracket 124. The bracket 124 supports the seal 125 to prevent the seal 125 from deforming when it is in contact with the sound-generating component 130, thus ensuring the sealing effect between the seal 125 and the sound-generating component 130.

[0078] The mounting surface 129 of the bracket 124 faces the sound-generating assembly 130, and the seal 125 is mounted on the mounting surface 129, thus the seal 125 protrudes from the mounting surface 129. A first protrusion 123 is provided on the side of the bracket 124, and the first protrusion 123 also protrudes from the mounting surface 129. The height H1 of the seal 125 protruding from the mounting surface 129 is greater than the height H2 of the first protrusion 123 protruding from the mounting surface 129; therefore, the first protrusion 123 protrudes from the seal 125.

[0079] During the installation of the sound-generating component 130, the side wall 136 pushes the first protrusion 123. At this time, it is not desirable for the side wall 136 to rub against the seal 125. Therefore, the first protrusion 123 is provided to protrude from the seal 125. During the movement of the sound-generating component 130 into the mounting cavity 111, the side wall 136 contacts the first protrusion 123, while there is a gap between the side wall 136 and the seal 125 to ensure that the seal 125 will not be deformed during the installation of the sound-generating component 130.

[0080] like Figure 14 As shown, in some embodiments, optionally, before the sound-generating assembly 130 is installed into the frame 110, the distance between the abutment surface 1231 and the side wall 136 in a direction perpendicular to the side wall 136 is greater than the distance between the sealing side 1221 and the side wall 136.

[0081] Before the sound-generating component 130 is installed, both the first protrusion 123 and the sealing part 122 interfere with the sound-generating component 130.

[0082] D1 is the interference amount between the first protrusion 123 and the sound-generating component 130, and D2 is the interference amount between the sealing part 122 and the sound-generating component 130. When the first protrusion 123 is in contact with the side wall 136, there is a gap between the sealing part 122 and the side wall 136 to prevent the sound-generating component 130 from rubbing against the sealing part 122.

[0083] In some embodiments, optionally, when the sound-generating assembly 130 is moved to the mounting position, the sealing portion 122 is in a deformed state; or when the sound-generating assembly 130 is moved to the mounting position, both the sealing portion 122 and the elastic portion 121 are in a deformed state.

[0084] When the sound-generating component 130 is installed in place, the sealing part 122 is in a deformed state, thereby ensuring that the sealing part 122 and the sound-generating component 130 are tightly fitted, and ensuring the sealing effect between the sealing part 122 and the sound-generating component 130.

[0085] When the sound-generating assembly 130 is moved to the mounting position, only the sealing part 122 may deform, while the elastic part 121 has returned to its original shape; that is, the elastic part 121 is not compressed at this time. To meet the above conditions, the elastic coefficient of the elastic part 121 may be set to be greater than that of the sealing part 122, making the sealing part 122 more easily deformable, thereby ensuring that the sealing part 122 can fit tightly against the sound-generating assembly 130 through deformation.

[0086] Alternatively, when the sound-generating component 130 is moved to the mounting position, both the sealing part 122 and the elastic part 121 are in a deformed state. The sealing part 122 fits tightly against the sound-generating component 130 through deformation, and the elastic part 121 provides a pushing force to the sealing part 122 while in a deformed state, which helps the sealing part 122 fit more tightly against the sound-generating component 130.

[0087] For example, electronic device 100 can be a mobile phone, tablet computer, laptop computer, e-reader, smart wearable device, etc.
