Description

Technical Field

[0001] The utility model relates to the technical field of sound-generating devices, in particular to a mounting structure, a sound-generating device and a swing chair. Background Art

[0002] Speakers are common sound-generating components. In the related art, when fixing the speaker, glue is used to bond the outer periphery of the speaker to the base. In this mounting structure, after the speaker has been used for a long time, on the one hand, the glue is prone to aging, thereby reducing the bonding effect, and on the other hand, the vibration generated during the speaker's sound generation process is prone to cause it to separate from the glue. Therefore, the existing speaker mounting structure is not very stable for the installation of the speaker. Utility Model Content

[0003] The main purpose of the utility model is to provide a mounting structure, a sound-generating device and a swing chair, which can improve the connection stability of the sound-generating components.

[0004] To achieve the above purpose, the utility model proposes a mounting structure for mounting a sound generating component, the mounting structure comprising:

[0005] The base has a first wall surface, and the base includes an annular flange protruding from the first wall surface and a fixing portion located outside the annular flange;

[0006] The abutment member comprises a first end portion and a second end portion, wherein the first end portion is connected to the fixing portion, and when viewed in a direction perpendicular to the first wall surface, the second end portion is adapted to extend to the inner side of the annular flange;

[0007] The inner peripheral wall of the annular flange and the first wall surface jointly define a cavity suitable for accommodating the sound-generating component, and the second end portion is configured to be suitable for abutting against the sound-generating component located in the cavity.

[0008] In the above embodiment, the mounting structure includes a base and a supporting member, and the base and the supporting member are used to jointly mount and fix the sound-generating component. When the sound-generating component is installed, it is arranged in the annular flange, and the supporting member is connected to the base and abuts the second side of the sound-generating component, and the annular flange or the first wall abuts the first side of the sound-generating component, thereby fixing the sound-generating component. Compared with the structure of connecting and fixing the sound-generating component with glue, the mounting structure in the present application has higher connection stability for the sound-generating component, and the sound-generating component is not easy to separate from the base after a long period of use. In addition, in the present application, the first wall and the supporting member jointly limit the displacement of the sound-generating component in a direction perpendicular to the first wall, and the annular flange limits the displacement of the sound-generating component in a direction parallel to the first wall, which has a better limiting effect on the sound-generating component, making it less likely for the sound-generating component to be displaced relative to the base during operation. Further, in the present application, one end of the supporting member is connected to the fixing portion on the outer side of the annular flange, and the other end extends in the direction of the inner side of the annular flange. On the one hand, the supporting member is a cantilever beam type fixed structure. Compared with the solution in which the supporting member is fixed at both ends and supports the sound-emitting component in the middle, the structure in this solution can prevent the component from being crushed through a certain elastic deformation if the pressing force exceeds the limit during the process of the supporting member abutting the sound-emitting component; on the other hand, compared with the solution in which the supporting member is completely located on the inner side of the annular flange to support the sound-emitting component, the strength requirement of the annular flange can be reduced, and the size of the annular flange can be more matched with the size of the sound-emitting component, making the structural layout of the base more reasonable.

[0009] In some embodiments, an escape groove is provided at one end of the annular flange facing away from the first wall surface, and the supporting member is suitable for extending into the escape groove in a direction perpendicular to the first wall surface and passing through the escape groove in a direction parallel to the first wall surface.

[0010] In the above embodiment, position interference between the abutting member and the annular flange can be avoided.

[0011] In some embodiments, the abutment member includes a positioning portion located between the first end portion and the second end portion, and when viewed along a direction perpendicular to the first wall surface, the positioning portion is located inside the annular flange, and the positioning portion abuts against an inner peripheral wall of the annular flange;

[0012] Along the circumference of the inner peripheral wall, the positioning portion includes a first positioning end and a second positioning end that are arranged opposite to each other, and both the first positioning end and the second positioning end abut against the inner peripheral wall;

[0013] Optionally, the abutting member further includes a first rib located between the positioning portion and the first end portion, two ends of the first rib are respectively connected to the positioning portion and the first end portion, and the first rib is arranged through the avoidance groove;

[0014] A concave portion is provided on one side of the end portion of the first rib connected to the positioning portion and close to the annular flange, and the bottom wall of the avoidance groove extends into the concave portion;

[0015] Optionally, the inner peripheral wall of the annular flange is connected to a plurality of second ribs, and the second ribs are arranged at intervals along the circumferential direction of the inner peripheral wall;

[0016] The positioning portion abuts against an end portion of at least one second rib facing away from the first wall surface.

[0017] In the above embodiment, the mounting structure has a higher connection stability for the sound-generating component, and the sound-generating component is not easy to separate from the base after a long period of use. In addition, on the one hand, the positioning portion extends along the circumference of the inner peripheral wall of the annular flange and abuts against the inner peripheral wall, which can produce positional interference between the wall positioning portion and the sound-generating component located in the annular flange, compared with a structure in which the positioning portion extends along the circumference of the annular flange toward the direction close to the first wall surface and the end close to the first wall surface abuts against the inner peripheral wall. On the other hand, both ends of the positioning portion along the circumference of the inner peripheral wall abut against the inner peripheral wall, which has a better positioning effect than a structure in which one end abuts against the inner peripheral wall.

[0018] In some embodiments, the fixing portion is protruding from the first wall surface, the first end portion is provided with a mounting hole, the fixing portion is passed through the mounting hole and fixedly connected to the first end portion;

[0019] The inner wall of the mounting hole is provided with a plurality of third ribs, the third ribs are distributed at intervals along the circumference of the mounting hole, and the third ribs are interference fit with the fixing portion.

[0020] In the above embodiment, the positioning of the supporting member and the fixing portion is more convenient.

[0021] In some embodiments, along a direction perpendicular to the first wall, a height dimension of the first end is H1, and a height dimension of the second end is H2, wherein H2 ≥ H1;

[0022] Optionally, the direction from the first end to the second end is the first direction, the second direction is parallel to the first wall and perpendicular to the first direction, and along the second direction, the width dimension of the first end is D1, and the width dimension of the second end is D2, wherein D2≥D1 / 2.

[0023] In the above embodiment, the second end portion is more convenient to extend into the annular flange to abut against the sound-emitting component; at the same time, the second end portion can contact the sound-emitting component with a sufficiently large area, thereby improving the positioning effect of the second end portion on the sound-emitting component.

[0024] In some embodiments, the second end comprises:

[0025] An extension block extending in a direction away from the first end;

[0026] A supporting block connected to an end of the extension block away from the first end and extending toward the first wall surface, wherein the end of the supporting block away from the extension block is suitable for supporting the sound generating component;

[0027] a fourth rib connected to a side of the abutting block close to the first end and to a side of the extending block facing the first wall;

[0028] Optionally, the second end further includes a reinforcing column connected to a side of the extension block facing the first wall and extending in a direction close to the first wall; the fourth rib is connected to the reinforcing column, and the reinforcing column is spaced apart from the supporting block.

[0029] In the above embodiment, the second end has a better positioning effect on the sound-generating component.

[0030] In some embodiments, the wall surface of the fourth rib facing the first wall surface is the second wall surface, and one end of the second wall surface close to the abutting block is flush with the wall surface of the abutting block facing the first wall surface, and the second wall surface gradually moves away from the first wall surface in a direction away from the abutting block;

[0031] Optionally, the direction from the first end to the second end is the first direction, the second direction is parallel to the first wall and perpendicular to the first direction, and along the second direction, the width dimension of the second end is D2, and the width dimension of the reinforcing column is D3, wherein 1 / 3≤D3 / D2≤2 / 3.

[0032] In the above embodiment, the end of the second wall surface close to the abutment block is flush with the wall surface of the abutment block facing the first wall surface, so that the strength improvement effect of the fourth rib is better; the structural setting of the second wall surface gradually moving away from the first wall surface in the direction away from the abutment block makes it difficult for the fourth rib to interfere with the sound component, which is more conducive to the abutment block to abut the sound component. In addition, it can also have a better reinforcement effect under the premise of an appropriate volume of the reinforcement column.

[0033] In some embodiments, the annular flange is further provided with a wire groove, which is suitable for passing the wire of the sound-generating component, and the wire groove is located at the end of the annular flange away from the first wall surface;

[0034] Optionally, the base is provided with a sound-emitting hole penetrating the first wall surface, and when viewed in a direction perpendicular to the first wall surface, the sound-emitting hole is partially located within the annular flange;

[0035] Optionally, a support rib is further provided between the fixing portion and the annular flange, and the abutting member abuts against an end of the support rib facing away from the first wall surface.

[0036] In the above embodiment, the support rib can support the abutting member on the one hand, and can also fix the relative position between the fixing portion and the annular flange on the other hand, thereby improving the positioning accuracy of the abutting member.

[0076] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0077] The speaker is a common sound-generating component. In the related art, when fixing the speaker, glue is used to bond the outer periphery of the speaker to the base. In this installation structure, after the speaker has been used for a long time, on the one hand, the glue is prone to aging and thus reduces the bonding effect, and on the other hand, the vibration generated during the sound-generating process of the speaker is prone to cause it to separate from the glue. Therefore, the existing speaker installation structure is not very stable for the installation of the speaker. The applicant initially considered that a fixing component could be used to fix the speaker. In order to prevent the fixing component from affecting the vibration and sound of the sound-generating component of the speaker, the fixing component can fix the back side of the speaker. Specifically, both ends of the fixing component are fixed to the base, and the middle part of the fixing component presses the back side of the speaker. This solution is relatively stable for fixing the speaker.

[0078] In view of this, see Figure 1-Figure 8 , this embodiment provides a mounting structure 100, which is used to install a sound-generating component 200, and can improve the connection stability of the sound-generating device 10. The sound-generating component 200 is a component that can vibrate and produce sound, and it may include a first side that vibrates and produces sound and a second side 210 opposite to the first side. Specifically, the sound-generating component 200 includes a diaphragm for vibrating and producing sound, a coil winding connected to the diaphragm, and a permanent magnet magnetically coupled to the coil winding. After the coil winding is energized, it vibrates in the magnetic field of the permanent magnet, thereby driving the diaphragm to vibrate and produce sound, wherein the diaphragm is located on the first side of the sound-generating component 200, and the permanent magnet and the protective shell connected to the permanent magnet are located on the second side 210 of the sound-generating component 200.

[0079] See also Figure 1-Figure 3 The mounting structure 100 includes a base 110 and a supporting member 120, and the supporting member 120 is used to fix the sound-generating component 200 to the base 110. The base 110 has a first wall surface 111, and the first wall surface 111 is the inner wall surface of the base 110, that is, when the sound-generating device 10 composed of the sound-generating component 200 and other necessary components is working after the sound-generating component 200 is mounted on the mounting structure 100, the first wall surface 111 is located on the inner side of the base 110. The sound-generating component 200 is also located on the inner side of the base 110. In order to facilitate the output of the sound generated by the sound-generating component 200, the base 110 may be provided with a plurality of sound-generating holes 116 penetrating the first wall surface 111, and the sound generated by the sound-generating component 200 located on the inner side of the base 110 is output to the outside of the base 110 through the sound-generating holes 116.

[0080] See also Figure 1-Figure 3 The base 110 includes an annular flange 112 protruding from the first wall surface 111 and a fixing portion 113 located outside the annular flange 112. When viewed in a direction perpendicular to the first wall surface 111, some of the plurality of sound holes 116 are located inside the annular flange 112. The annular flange 112 has an inner peripheral wall 1123, and the inner peripheral wall 1123 of the annular flange 112 and the first wall surface 111 together define a cavity suitable for accommodating the sound component 200. The sound component 200 is disposed inside the annular flange 112, and the first side of the sound component 200 is opposite to the first wall surface 111, so that the sound emitted from the first side of the sound component 200 can be guided to the outside of the base 110 through the sound hole 116. The second side 210 of the sound-emitting component 200 is arranged away from the first wall surface 111, and the second side 210 of the sound-emitting component 200 can be located inside the annular flange 112 (the second side 210 of the sound-emitting component 200 does not exceed the end of the annular flange 112 away from the first wall surface 111), and the second side 210 of the sound-emitting component 200 can also extend out of the annular flange 112 in a direction away from the first wall surface 111. In this embodiment, the sound-emitting component 200 is completely located inside the annular flange 112. The fixing portion 113 is located outside the annular flange 112, and the fixing portion 113 is used to connect the abutment 120. The specific structure of the fixing portion 113 and the connection method with the abutment 120 depend on actual needs. In this embodiment, the fixing portion 113 is protruding from the first wall surface 111 and connected to the abutment 120. The fixing portion 113 is convexly disposed on the first wall surface 111, so that the distance of the abutting member 120 relative to the first wall surface 111 can be raised, so that the structural size of the portion where the abutting member 120 is connected to the base 110 can be smaller. In other embodiments, the fixing portion 113 can also be a groove arranged by the first wall surface 111, and the abutting member 120 is inserted into the groove to be fixed to the base 110.

[0081] See also Figure 2 as well as Figure 6-Figure 8, the abutment 120 includes a first end 121 and a second end 122. The first end 121 and the second end 122 are two ends of the abutment 120. In some embodiments, the abutment 120 may include only the first end 121 and the second end 122. In other embodiments, the abutment 120 may also include three ends or four ends. Specifically, in this embodiment, the first end 121 and the second end 122 are arranged along the first direction X, that is, the first end 121 and the second end 122 are distributed at both ends of the abutment 120 along the first direction X. In other embodiments, the first end 121 and the second end 122 may be arranged along any direction on the plane formed by the first direction X and the second direction Y. In other embodiments, the first end 121 and the second end 122 may also have other relative positions. For example, when the abutment 120 includes three ends or four ends, the first end 121 and the second end 122 may also be distributed at the same end of the abutment 120 along a certain direction and the two are adjacent and spaced. The first end 121 is connected to the fixing portion 113, and the second end 122 is located inside the annular flange 112 when viewed in a direction perpendicular to the first wall surface 111 (i.e., the third direction Z). In other words, the projection plane is parallel to the first wall surface 111, and the projection formed by the second end 122 on the projection plane is located inside the projection formed by the annular flange 112 on the projection plane. The second end 122 is configured to be suitable for abutting against the second side 210 of the sound component 200 located in the cavity. Specifically, the second end 122 abuts against the permanent magnet of the sound component 200, or against the protective shell of the sound component 200 that protects the permanent magnet. Compared with the structure of connecting and fixing the sound component 200 with glue, the mounting structure 100 in this embodiment has higher connection stability for the sound component 200, and the sound component 200 is not easy to separate from the base 110 after a long period of use.

[0082] Moreover, in this embodiment, the first wall surface 111 and the abutting member 120 jointly limit the displacement of the sound component 200 in a direction perpendicular to the first wall surface 111, and the annular flange 112 limits the displacement of the sound component 200 in a direction parallel to the first wall surface 111, which has a better limiting effect on the sound component 200, making it less likely for the sound component 200 to be displaced relative to the base 110 during operation. Further, in this embodiment, one end of the abutting member 120 is connected to the fixing portion 113 on the outer side of the annular flange 112, and one end extends toward the inner side of the annular flange 112. On the one hand, the abutting member 120 is a cantilever beam type fixed structure. Compared with the solution in which the two ends of the abutting member 120 are fixed and the middle abuts the sound component 200, the structure in this solution allows the abutting member 120 to prevent the component from being crushed by a certain elastic deformation if the pressing force exceeds the limit during the process of abutting the sound component 200; on the other hand, compared with the solution in which the abutting member 120 is completely located inside the annular flange 112 to abut the sound component 200, the strength requirement of the annular flange 112 can be reduced, and the size of the annular flange 112 can be more matched with the size of the sound component 200, so that the structural layout of the base 110 is more reasonable. Because when the abutting member 120 is completely located inside the annular flange 112, either the abutting member 120 is fixed to the annular flange 112, which requires an increase in the structural strength of the annular flange 112; or the abutting member 120 is fixed to the first wall surface 111, which increases the volume of the annular flange 112 and makes the spatial layout of the internal structure of the base 110 unreasonable.

[0083] See also Figure 2-Figure 5In some embodiments, an end of the annular flange 112 facing away from the first wall surface 111 is provided with an avoidance groove 1121, and the abutting member 120 extends into the avoidance groove 1121 in a direction perpendicular to the first wall surface 111, and passes through the avoidance groove 1121 in a direction parallel to the first wall surface 111. Since the abutting member 120 extends from the outside of the annular flange 112 to the inside of the annular flange 112 to abut the sound generating assembly 200, the provision of the avoidance groove 1121 can make it difficult for the abutting member 120 and the annular flange 112 to have positional interference, thereby reducing the requirements for the processing accuracy and assembly accuracy of the annular flange 112 and the abutting member 120. Furthermore, since the annular flange 112 is provided with the avoidance groove 1121, and the supporting member 120 extends into the avoidance groove 1121 in a direction perpendicular to the first wall surface 111, compared with the structure in which the annular flange 112 is not provided with the avoidance groove 1121, the distance between the supporting member 120 and the first wall surface 111 can be closer. On the one hand, the first end 121 of the supporting member 120 is closer to the fixing portion 113, and the two are easier to connect; on the other hand, the second end 122 of the supporting member 120 is closer to the sound-emitting component 200, and the second end 122 is more convenient for resisting the sound-emitting component 200. In particular, when the supporting member 120 is extended into the avoidance groove 1121, the avoidance groove 1121 can also position the supporting member 120. Specifically, the avoidance groove 1121 can position the relative arrangement position of the supporting member 120 and the annular flange 112. When the supporting member 120 is assembled, it is only necessary to ensure that the supporting member 120 is extended into the avoidance groove 1121, and the relative position of the second end portion 122 and the sound-emitting component 200 can be adjusted. Therefore, there is no need to pay special attention to the relative position of the second end portion 122 and the sound-emitting component 200, and the assembly process of the supporting member 120 is simpler.

[0084] In the above embodiment, the relative position of the abutting member 120 and the annular flange 112 is limited by providing the avoidance groove 1121 on the annular flange 112. Figure 5-Figure 6 In some embodiments, the relative position of the abutting member 120 and the annular flange 112 can be defined by providing a positioning portion 124. Specifically, the abutting member 120 includes a positioning portion 124 located between the first end 121 and the second end 122. When viewed in a direction perpendicular to the first wall surface 111, the positioning portion 124 is located inside the annular flange 112, and the positioning portion 124 abuts against the inner peripheral wall 1123 of the annular flange 112. In this solution, the relative position of the abutting member 120 and the annular flange 112 is defined by providing the positioning portion 124 and making the positioning portion 124 abut against the inner peripheral wall 1123 of the annular flange 112, thereby determining the relative position of the second end 122 and the sound generating assembly 200. In other embodiments, the positioning portion 124 can also be located outside the annular flange 112, and the positioning portion 124 abuts against the outer peripheral wall of the annular flange 112.

[0085] In some embodiments, the abutting member 120 may be provided with a positioning portion 124, the positioning portion 124 abuts against the inner circumferential wall 1123 of the annular flange 112, and the annular flange 112 is not provided with the avoidance groove 1121. In this case, the abutting member 120 is located relative to the annular flange 112 only through the positioning portion 124. In other embodiments, the abutting member 120 may not be provided with a positioning portion 124, and the annular flange 112 is provided with the avoidance groove 1121. In this case, the abutting member 120 is located relative to the annular flange 112 only through the avoidance groove 1121. Figure 5-Figure 6 In this embodiment, the supporting member 120 is provided with a positioning portion 124, and the annular flange 112 is provided with an avoidance groove 1121, and the relative positions of the supporting member 120 and the annular flange 112 are jointly positioned by the positioning portion 124 and the avoidance groove 1121.

[0086] See also Figure 5-Figure 6 as well as Figure 8 In some embodiments, along the circumference of the inner peripheral wall 1123 of the annular flange 112, the positioning portion 124 includes a first positioning end 1241 and a second positioning end 1242 arranged opposite to each other, and the first positioning end 1241 and the second positioning end 1242 both abut against the inner peripheral wall 1123. In this solution, on the one hand, the positioning portion 124 extends along the circumference of the inner peripheral wall 1123 of the annular flange 112 and abuts against the inner peripheral wall 1123, which can generate positional interference between the wall positioning portion 124 and the sound generating assembly 200 located in the annular flange 112, compared with the structure in which the positioning portion 124 extends along the circumference of the annular flange 112 in the direction close to the first wall surface 111 and the end close to the first wall surface 111 abuts against the inner peripheral wall 1123. On the other hand, both ends of the positioning portion 124 along the circumference of the inner peripheral wall 1123 abut against the inner peripheral wall 1123, which has a better positioning effect than the structure in which one end abuts against the inner peripheral wall 1123.

[0087] See also Figure 5-Figure 6 as well as Figure 8 In some embodiments, the abutting member 120 further includes a first rib 123 located between the positioning portion 124 and the first end portion 121, the two ends of the first rib 123 are respectively connected to the positioning portion 124 and the first end portion 121, and the first rib 123 is arranged through the avoidance groove 1121, and along the circumference of the annular flange 112, the first positioning end 1241 and the second positioning end 1242 are respectively located on both sides of the first rib 123. In this solution, the provision of the first rib 123 can enhance the strength of the positioning portion 124 and reduce the possibility of deformation of the positioning portion 124. At the same time, the first rib 123 can also fix the relative position between the positioning portion 124 and the first end portion 121, thereby improving the positioning accuracy of the positioning portion 124.

[0088] In some embodiments, when the first rib 123 passes through the avoidance groove 1121, the first rib 123 may be arranged at a distance from the groove wall of the avoidance groove 1121. In another embodiment, the first rib 123 may also be arranged in contact with the groove wall of the avoidance groove 1121. When the first rib 123 is arranged in contact with the groove wall of the avoidance groove 1121, see Figure 5-Figure 6 as well as Figure 8 In some embodiments, a recess 1231 is provided on one side of the end of the first rib 123 connected to the positioning portion 124 and close to the annular flange 112, and the bottom wall of the avoidance groove 1121 extends into the recess 1231, and the bottom wall of the avoidance groove 1121 abuts against the wall surface of the recess 1231. The provision of the recess 1231 can locate the relative position of the first rib 123 and the annular flange 112, thereby further improving the positioning accuracy of the abutting member 120. At the same time, the provision of the recess 1231 can further reduce the possibility of position interference between the first rib 123 and the annular flange 112.

[0089] In order to improve the structural strength of the annular flange 112, see Figure 4-Figure 6 as well as Figure 8 In some embodiments, the inner circumferential wall 1123 of the annular flange 112 is connected with a plurality of second ribs 115, and each second rib 115 is arranged at intervals along the circumference of the inner circumferential wall 1123. Specifically, in this embodiment, the inner circumferential wall 1123 of the annular flange 112 is provided with six second ribs 115, and the six second ribs 115 are arranged at equal intervals along the circumference of the annular flange 112, and each second rib 115 is respectively connected to the inner circumferential wall 1123 of the annular flange 112 and the first wall surface 111, so as to improve the structural strength of the annular flange 112. In addition, when the sound assembly 200 is installed in the annular flange 112, the second rib 115 can produce an interference fit with the sound assembly 200, further enhancing the installation stability of the sound assembly 200. Furthermore, the positioning portion 124 of the abutting member 120 abuts against the end of at least one second rib 115 away from the first wall surface 111. In this solution, the second rib 115 can support the end of the positioning portion 124 close to the first wall 111 to position the abutment 120 in a direction perpendicular to the first wall 111 , thereby avoiding positional interference between the positioning portion 124 and the sound generating assembly 200 .

[0090] See also Figure 1-Figure 3 as well as Figure 7In some embodiments, the fixing portion 113 is protruded from the first wall surface 111, and the first end portion 121 is provided with a mounting hole 1211. The fixing portion 113 is passed through the mounting hole 1211 and is connected to the first end portion 121 by at least one of threaded connection, interference fit connection, welding or adhesive connection. In this embodiment, the fixing portion 113 and the first end portion 121 are connected by interference fit, and in order to improve the assembly stability and convenience between the fixing portion 113 and the first end portion 121, see Figure 7 , the inner wall of the mounting hole 1211 is provided with a plurality of third ribs 1212, each of which is spaced apart along the circumference of the mounting hole 1211, and each of which is interference fit with the fixing portion 113. In this scheme, after the mounting hole 1211 of the first end portion 121 is aligned with the upper end position of the fixing portion 113, the first end portion 121 is driven downward and the fixing portion 113 is inserted into the mounting hole 1211, so that the fixing portion 113 and the first end portion 121 are matched, and the installation process is simpler. In addition, the above-mentioned assembly method of the fixing portion 113 and the second end portion 122 is also more convenient for the first rib 123 to match with the avoidance groove 1121, the concave portion 1231 of the first rib 123 to match with the groove wall of the avoidance groove 1121, the positioning portion 124 to match with the inner peripheral wall 1123 of the annular flange 112, and the positioning portion 124 to match with the first rib 123.

[0091] See also Figure 7-Figure 8 In some embodiments, along the direction perpendicular to the first wall 111, the height dimension of the first end 121 is H1, and the height dimension of the second end 122 is H2, wherein H2≥H1. In this solution, the second end 122 is more convenient to extend into the annular flange 112 so as to abut against the sound component 200. In some embodiments, the direction from the first end 121 to the second end 122 is the first direction X, and the second direction Y is parallel to the first wall 111 and perpendicular to the first direction X. Along the second direction Y, the width dimension of the first end 121 is D1, and the width dimension of the second end 122 is D2, wherein D2≥D1 / 2. In this solution, the second end 122 can contact the sound component 200 with a sufficiently large area, thereby improving the positioning effect of the second end 122 on the sound component 200.

[0092] See also Figure 6-Figure 8In some embodiments, the second end portion 122 includes an extension block 1221, a support block 1222, a fourth rib 1223, and a reinforcing column 1224. The extension block 1221 extends in a direction away from the first end portion 121. The support block 1222 connects one end of the extension block 1221 away from the first end portion 121 and extends in a direction close to the first wall surface 111. The end of the support block 1222 away from the extension block 1221 is suitable for abutting the second side 210 of the sound generating assembly 200. The fourth rib 1223 connects a side of the support block 1222 close to the first end portion 121 and connects a side of the extension block 1221 facing the first wall surface 111. The reinforcing column 1224 is connected to a side of the extension block 1221 facing the first wall surface 111 and extends in a direction close to the first wall surface 111. The fourth rib 1223 connects the reinforcing column 1224, and the reinforcing column 1224 is spaced apart from the support block 1222. In this solution, the fourth rib 1223 can improve the structural strength of the abutting block 1222 and prevent the abutting block 1222 from being deformed. The provision of the reinforcing column 1224 can further improve the structural strength of the fourth rib 1223. The specific structure and arrangement position of the reinforcing column 1224 depend on actual needs. In this embodiment, the reinforcing column 1224 extends along the third direction Z, and the cross-section of the reinforcing column 1224 along the direction parallel to the first wall surface 111 is circular, and the reinforcing column 1224 passes through the fourth rib 1223, so that a part of the fourth rib 1223 is located between the reinforcing column 1224 and the abutting block 1222, and a part is located on the side of the reinforcing column 1224 away from the abutting block 1222.

[0093] The size of the reinforcing column 1224 along the second direction Y cannot be too large or too small. When the size (specifically, the diameter) of the reinforcing column 1224 along the second direction Y is too large, the material redundancy of the abutting member 120 is too large and the material cost is too high; when the size of the reinforcing column 1224 along the second direction Y is too small, the reinforcing effect is not obvious. Figure 6-Figure 8 In some embodiments, along the second direction Y, the width dimension of the second end portion 122 is D2, and the width dimension of the reinforcing column 1224 is D3, wherein 1 / 3≤D3 / D2≤2 / 3. For example, D3 / D2 may be 1 / 3, 4 / 9, 5 / 9, or 2 / 3. In this solution, when 1 / 3≤D3 / D2≤2 / 3, a better reinforcement effect can be achieved under the premise that the volume of the reinforcing column 1224 is appropriate.

[0094] See also Figure 6-Figure 8In some embodiments, the wall surface of the fourth rib 1223 facing the first wall surface 111 is the second wall surface 1225, and one end of the second wall surface 1225 close to the abutting block 1222 is flush with the wall surface of the abutting block 1222 facing the first wall surface 111, and the second wall surface 1225 gradually moves away from the first wall surface 111 in a direction away from the abutting block 1222. In this solution, one end of the second wall surface 1225 close to the abutting block 1222 is flush with the wall surface of the abutting block 1222 facing the first wall surface 111, so that the strength improvement effect of the fourth rib 1223 is better; the structural setting that the second wall surface 1225 gradually moves away from the first wall surface 111 in a direction away from the abutting block 1222 makes it difficult for the fourth rib 1223 to cause position interference with the sound generating component 200, which is more conducive to the abutting block 1222 to abut the sound generating component 200.

[0095] See also Figure 4 In some embodiments, the annular flange 112 is further provided with a wire groove 1122, which is suitable for passing the wire of the sound component 200, and the wire groove 1122 is located at the end of the annular flange 112 away from the first wall 111. The wire of the sound component 200 passes through the wire groove 1122 to be electrically connected to the external power supply and the circuit board. In other embodiments, the wire groove 1122 of the annular flange 112 can also be set in the middle position along the third direction Z or at the end position connected to the first wall 111.

[0096] See also Figure 5-Figure 6 In some embodiments, a support rib 114 is further provided between the fixing portion 113 and the annular flange 112, and the abutting member 120 abuts against the end of the support rib 114 away from the first wall surface 111. The support rib 114 can support the abutting member 120 on the one hand, and can also fix the relative position between the fixing portion 113 and the annular flange 112 on the other hand, thereby improving the positioning accuracy of the abutting member 120.
