Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and more specifically, to a speaker. Background Technology

[0002] Speaker grilles not only enhance the speaker's aesthetics but also protect the speaker units from damage caused by dust, foreign objects, or accidental impacts. Typically, speaker grilles have connecting posts, while the speaker cabinet or speaker itself has connecting holes. The connection between the grille and the cabinet or speaker usually relies on a simple plug-in fit, where the connecting posts on the grille directly mate with the connecting holes on the cabinet or speaker. However, over time, this traditional plug-in fit can loosen, causing the grille to vibrate slightly when the speaker is playing music. This vibration can interfere with sound wave transmission and lead to a decrease in sound quality. Utility Model Content

[0003] This invention provides a speaker to solve the problem that in the prior art, the connection between the connecting post on the grille and the connecting hole on the cabinet or speaker causes the grille to vibrate slightly when the speaker plays music. This vibration interferes with the transmission of sound waves and causes a decrease in sound quality.

[0004] This utility model provides a speaker, comprising: a cabinet; a speaker disposed on the cabinet, the speaker including a cone, the speaker and / or the cabinet having a connection hole located on the outer periphery of the cone, the connection hole having a limiting surface inside the connection hole, the limiting surface including an arcuate surface, the arcuate surface protruding radially away from the axis of the connection hole; a grille disposed opposite to the speaker; and a connecting structure, one end of the connecting structure being fixedly disposed on the grille, the connecting structure including a limiting part made of elastic material, the limiting part passing through the connection hole and engaging with the connection hole, at least a portion of the outer surface contour of the limiting part being adapted to the contour of the limiting surface, the limiting part engaging with the limiting surface to limit the position of the connecting structure at the connection hole.

[0005] Furthermore, multiple limiting surfaces are provided, and the multiple limiting surfaces are distributed at intervals along the circumference of the connecting hole; or, the circumferential surface of the connecting hole forms a limiting surface.

[0006] Furthermore, multiple limiting ribs are provided inside the connecting hole. The multiple limiting ribs are distributed at intervals along the circumference of the connecting hole and extend along the axial direction of the connecting hole. Each limiting rib has a limiting surface on the side facing the axial direction of the connecting hole.

[0007] Furthermore, the end of the limiting rib facing the opening of the connecting hole has a guide surface, which is inclined relative to the axial direction of the connecting hole to form a flared structure.

[0008] Furthermore, when the limiting part and the limiting surface are engaged in limiting cooperation, there is a gap between the end of the connecting structure away from the mesh cover and the bottom of the connecting hole.

[0009] Furthermore, the connecting structure also includes a connecting post, one end of which is fixedly mounted on the mesh cover. The limiting part includes a rubber sleeve, and the end of the connecting post away from the mesh cover passes through the rubber sleeve and is fixedly connected to the rubber sleeve.

[0010] Furthermore, the rubber sleeve includes an end plate and an annular cylinder. The end plate is located at one end of the annular cylinder, and the end of the connecting post away from the mesh cover passes through the annular cylinder and abuts against the end plate.

[0011] Furthermore, the connection structure also includes a fastener, one end of which passes through a rubber sleeve and is detachably connected to the connecting post.

[0012] Furthermore, the connecting column and the mesh cover are integrally formed.

[0013] Furthermore, the connecting column includes a first section, a transition section, and a second section connected sequentially along the axial direction. The outer diameter of the first section is larger than that of the second section. The outer diameter of the transition section gradually decreases from the first section to the second section. The first section is a hollow structure. The end of the first section away from the transition section is fixedly connected to the mesh cover. The second section is inserted into the rubber sleeve. A first reinforcing rib is also provided on the outer wall at the connection position between the transition section and the second section.

[0014] Furthermore, the loudspeaker also includes a retaining ring, which is arranged in a ring around the outer periphery of the cone. The retaining ring is fixedly mounted on the cabinet, and the connecting hole is located on the retaining ring.

[0015] Furthermore, the fixing ring includes an integrally formed body portion and a connecting protrusion. The body portion is annularly disposed on the outer periphery of the cone, and the connecting protrusion is disposed on the side of the body portion facing the cabinet. A connecting hole is disposed on the connecting protrusion. And / or, one side of the cabinet has a mounting cavity and a mounting groove. The mounting groove is annularly disposed at the opening of the mounting cavity and communicates with the mounting cavity. The cone is disposed in the mounting cavity, and the fixing ring is annularly disposed in the mounting groove.

[0016] By applying the technical solution of this utility model, the stability of the connection structure and the connection hole can be improved, reducing the vibration of the grille caused by loose connection of the connection structure and the connection hole when the speaker plays music, and reducing the possibility of sound quality degradation. Specifically, the limiting surface in the connection hole includes an arc-shaped surface, and the arc-shaped surface protrudes in the radial direction away from the axis of the connection hole; the limiting part of the connection structure is made of elastic material, and the limiting part passes through the connection hole and is inserted into the connection hole, with the limiting surface and the peripheral surface of the limiting part being adapted.

[0017] Understandably, the limiting surface is arc-shaped. Along the axial direction of the connecting hole, the distance from the end of the limiting surface to the axis of the connecting hole is less than the distance from the middle of the limiting surface to the axis of the connecting hole. This design allows the limiting part to be restricted from moving along the axial direction of the connecting hole after it extends into the limiting hole under the action of extrusion force. The arc-shaped design of the limiting surface, combined with the characteristics of the elastic limiting part, can generate sufficient friction to limit the position of the connecting structure in the radial direction. Furthermore, the damping function of the elastic material limiting part can absorb some energy when the speaker vibrates, reducing the vibration amplitude of the grille and further ensuring the stability of the speaker's sound quality.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0035] like Figures 1 to 4 As shown, this embodiment of the utility model provides a speaker, which includes a cabinet 10, a speaker, a grille 40, and a connecting structure 50. The speaker is mounted on the cabinet 10 and includes a cone 20. A connecting hole 30 is provided on the speaker and / or the cabinet 10. The connecting hole 30 is located on the radial outer periphery of the cone 20. A limiting surface 301 is provided inside the connecting hole 30. The limiting surface 301 includes an arc-shaped surface that protrudes radially away from the axis of the connecting hole 30. The grille 40 is disposed opposite to the speaker. One end of the connecting structure 50 is fixedly mounted on the grille 40. The connecting structure 50 includes a limiting part 51 made of elastic material. The limiting part 51 passes through the connecting hole 30 and is inserted into the connecting hole 30. At least a portion of the outer surface of the limiting part 51 is adapted to the contour of the limiting surface 301. The limiting part 51 and the limiting surface 301 limit each other to restrict the position of the connecting structure 50 at the connecting hole 30.

[0036] By applying the technical solution of this utility model, the stability of the connection between the connecting structure 50 and the connecting hole 30 can be improved, reducing the vibration of the grille 40 caused by the loose connection between the connecting structure 50 and the connecting hole 30 when the speaker is playing music, and reducing the possibility of a decrease in speaker sound quality. Specifically, the limiting surface 301 inside the connecting hole 30 is an arc-shaped surface, and in the radial direction of the connecting hole 30, the arc-shaped limiting surface 301 protrudes away from the axis of the connecting hole 30; the limiting part 51 of the connecting structure 50 is made of elastic material, and the limiting part 51 passes through the connecting hole 30 and is inserted into the connecting hole 30, with the limiting surface 301 and the peripheral surface of the limiting part 51 adapted to each other.

[0037] It is understandable that the limiting surface 301 is an arc-shaped surface. Along the axial direction of the connecting hole 30, the distance from the end of the limiting surface 301 to the axis of the connecting hole 30 is less than the distance from the middle of the limiting surface 301 to the axis of the connecting hole 30. This setting allows the limiting part 51 to be restricted from moving in the axial direction of the connecting hole 30 after it extends into the connecting hole 30 under the action of the pressing force. The arc-shaped design of the limiting surface 301 combined with the characteristics of the elastic limiting part 51 can generate sufficient friction to limit the position of the connecting structure 50 in the radial direction. Furthermore, the damping function of the elastic material limiting part 51 can absorb some energy when the speaker vibrates, reducing the vibration amplitude of the grille 40 and further ensuring the stability of the speaker's sound quality.

[0038] In this design, multiple matching connection structures 50 and connection holes 30 are provided, and these multiple matching connection structures 50 and connection holes 30 are distributed at intervals along the circumference of the mesh cover 40. This arrangement can further improve the stability of the connection to the mesh cover 40.

[0039] In this embodiment of the solution, four interconnecting structures 50 and interconnecting holes 30 are provided.

[0040] In this embodiment of the solution, when the connecting structure 50 is inserted into place, there is a gap between the grille 40, the cone 20, and the enclosure 10. This arrangement avoids direct contact between the grille 40, the cone 20, and the enclosure 10, reducing noise caused by vibration and improving the sound quality of the speaker.

[0041] In this design, the outer peripheral surface of the limiting part 51 is similar to the circumferential shape of the middle part of an ellipsoid along the axial direction of its major axis.

[0042] This solution does not limit the form of the limiting surface 301. In some embodiments of this solution, the peripheral surface of the connecting hole 30 forms the limiting surface 301, and the outline of the limiting surface 301 is the same as the outline of the peripheral surface of the limiting part 51.

[0043] In other embodiments of this solution, multiple limiting surfaces 301 are provided, and the multiple limiting surfaces 301 are distributed at intervals along the circumference of the connecting hole 30. This arrangement enables the limiting part 51 to contact with the multiple limiting surfaces 301 and establish a limiting relationship when it is inserted into the connecting hole 30, thereby improving the smoothness of the insertion process of the limiting part 51.

[0044] like Figure 4As shown, specifically, multiple limiting ribs 31 are provided inside the connecting hole 30. These limiting ribs 31 are distributed at intervals along the circumference of the connecting hole 30 and extend along the axial direction of the connecting hole 30. Each limiting rib 31 has a limiting surface 301 on one side facing the axis of the connecting hole 30, and there is a gap between the limiting surface 301 and the bottom of the connecting hole 30. This arrangement facilitates the machining and forming of the limiting surface 301.

[0045] The above arrangement creates a recess between two adjacent limiting ribs 31. This arrangement allows the recess to accommodate the deformation of the limiting part 51 when it is inserted into the connecting hole 30, further improving the smoothness of insertion of the limiting part 51 into the connecting hole 30.

[0046] Furthermore, each limiting rib 31 has a flat surface on one side facing the axis of the connecting hole 30. This flat surface is located at one end of the limiting surface 301 near the bottom of the connecting hole 30, and this flat surface is parallel to the axis of the connecting hole 30. The end of the limiting part 51 near the bottom of the connecting hole 30 is disposed opposite to the flat surface, and there is a gap between the two.

[0047] To further improve the smoothness of insertion of the limiting part 51 into the connecting hole 30, the end of the limiting rib 31 facing the opening of the connecting hole 30 has a guide surface 311. The guide surface 311 is inclined relative to the axial direction of the connecting hole 30 to form a flared structure. In this embodiment, the guide surface 311 is connected to the side of the limiting rib 31 facing the axial direction of the connecting hole 30 by a rounded transition. This arrangement allows the guide surface 311 to guide the limiting part 51 during insertion into the connecting hole 30, further improving the smoothness of insertion.

[0048] It is understandable that the flared structure refers to the fact that the distance between the guide surface 311 and the bottom of the connecting hole 30 gradually decreases along the direction from the side wall of the connecting hole 30 to the axis.

[0049] Furthermore, when the limiting part 51 and the limiting surface 301 are engaged in a limiting fit, there is a gap between the end of the connecting structure 50 away from the mesh cover 40 and the bottom of the connecting hole 30. This arrangement can reduce the impact of speaker vibration on the connecting structure 50, reduce the occurrence of noise caused by the connecting structure 50 contacting the bottom of the connecting hole 30 as the speaker vibrates, and help improve the sound quality of the speaker.

[0050] like Figure 3As shown in the embodiment of this solution, the connecting structure 50 further includes a connecting post 52, which is made of a rigid material. One end of the connecting post 52 is fixedly mounted on the mesh cover 40. The limiting part 51 includes a rubber sleeve, and the end of the connecting post 52 away from the mesh cover 40 passes through the rubber sleeve and is fixedly connected to the rubber sleeve. This configuration can improve the rigidity of the connecting structure 50, so that when the limiting part 51 is inserted into the connecting hole 30, the entire connecting structure 50 can be more stably inserted into the connecting hole 30.

[0051] Specifically, the rubber sleeve includes an end plate 511 and an annular cylinder 512. The end plate 511 is located at one end of the annular cylinder 512, and the end of the connecting post 52 away from the mesh cover 40 passes through the annular cylinder 512 and abuts against the end plate 511. The connecting structure 50 also includes a fastener 53, one end of which passes through the rubber sleeve and is detachably connected to the connecting post 52. This configuration improves the stability of the connection between the rubber sleeve and the connecting post 52 and reduces the possibility of the rubber sleeve detaching from the connecting post 52.

[0052] In this embodiment, the fastener 53 is a fastening screw, which is threadedly connected to the connecting post 52. The fastening screw may be made of metal.

[0053] It is understandable that there is a gap between the end of the screw located outside the rubber sleeve and the bottom of the connecting hole 30.

[0054] In this embodiment, the connecting post 52 and the grille 40 are integrally molded. This design improves the stability of the connection between the connecting post 52 and the grille 40. The integrally molded connecting post 52 and grille 40 are assembled during the production stage, simplifying the final speaker assembly process. During assembly, no additional steps are required to secure the connecting post 52 and the grille 40.

[0055] In this embodiment, the mesh cover 40 and the connecting post 52 are formed by injection molding.

[0056] like Figure 5 and Figure 6 As shown, specifically, the connecting post 52 includes a first segment 521, a transition segment 522, and a second segment 523 connected sequentially along the axial direction. The outer diameter of the first segment 521 is larger than that of the second segment 523. The outer diameter of the transition segment 522 gradually decreases from the first segment 521 to the second segment 523. The first segment 521 is a hollow structure, and the end of the first segment 521 away from the transition segment 522 is open. The end of the first segment 521 away from the transition segment 522 is fixedly connected to the mesh cover 40. The second segment 523 is inserted into a rubber sleeve. This configuration improves the convenience of the injection molding process for the mesh cover and the connecting post 52, and saves injection molding materials while improving the connection strength between the connecting post 52 and the mesh cover 40, as well as the structural strength of the connecting post 52 itself.

[0057] In this embodiment of the solution, the end face of the second segment 523 away from the transition segment 522 is provided with a threaded hole, which is threadedly engaged with the fastening screw.

[0058] Furthermore, a first reinforcing rib is provided on the outer wall at the connection point between the transition section 522 and the second section 523. The provision of the first reinforcing rib can improve the connection strength at the connection point between the transition section 522 and the second section 523, and improve the overall structural strength of the connecting column 52.

[0059] In some embodiments of this solution, the connection hole 30 is provided on the housing 10.

[0060] like Figure 3 , Figure 4 and Figure 7 As shown in the embodiment of this solution, the loudspeaker also includes a fixing ring 60, which is arranged in a ring around the outer periphery of the cone 20. The fixing ring 60 is fixedly mounted on the enclosure 10, and the connecting hole 30 is disposed on the fixing ring 60. The fixing ring 60 provides an additional support point for the loudspeaker, avoiding the instability that may result from directly connecting the cone 20 to the enclosure 10. Distributing the connecting hole 30 on the fixing ring 60 facilitates the machining of the internal structure of the connecting hole 30.

[0061] Specifically, the retaining ring 60 includes an integrally formed body portion 61 and a connecting protrusion 62. The body portion 61 is arranged in a ring around the outer periphery of the cone 20, and the connecting protrusion 62 is located on the side of the body portion 61 facing the enclosure 10. A connecting hole 30 is located on the connecting protrusion 62. This arrangement improves the stability of the connection between the body portion 61 and the connecting protrusion 62 and facilitates the processing of the connecting hole 30.

[0062] In this embodiment, a second reinforcing rib is provided on the side of the main body 61 facing the housing 10. The provision of the second reinforcing rib can further improve the structural strength and stability of the fixing ring 60. A third reinforcing rib is also provided on the outer wall of the connecting protrusion 62. The provision of the third reinforcing rib can further improve the structural strength of the connecting protrusion 62, reduce the possibility of deformation of the connecting protrusion 62, and improve the stability of the limiting surface 301.

[0063] like Figure 2 and Figure 3As shown, further, one side of the enclosure 10 has a mounting cavity 101 and a mounting groove 102. The mounting groove 102 is arranged in a ring at the opening of the mounting cavity 101 and communicates with the mounting cavity 101. The cone 20 is disposed in the mounting cavity 101, and the fixing ring 60 is arranged in a ring at the mounting groove 102. The body portion 61 of the fixing ring 60 is arranged in a ring at the mounting groove 102, and the bottom of the mounting groove 102 is also provided with a clearance groove. The end of the connecting protrusion 62 away from the body portion 61 passes through the clearance groove.

[0064] In this embodiment, the outer periphery of the main body 61 is roughly flush with the surface of the cabinet 10, which improves the aesthetics of the speaker.
