Description

Technical Field

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

[0002] The speaker grille is not only an important part of beautifying the speaker's appearance, but also a crucial barrier protecting the internal speaker units from dust, foreign objects, and accidental impact damage. In traditional designs, the speaker grille is fixed in place by inserting it into the mounting holes on the speaker cabinet or speaker via connecting posts.

[0003] However, after prolonged use, the connection between the connector post and the connector hole may become loose. In particular, when the speaker is playing music, it generates strong vibrations. These vibrations can sometimes be transmitted to the connector post, causing the end of the connector post near the bottom of the connector hole to make rigid contact with the bottom of the connector hole. That is, the end of the connector post near the connector hole does not collide with the bottom of the connector hole, generating additional noise and affecting the sound quality of the speaker. Utility Model Content

[0004] This utility model provides a speaker to solve the problem in the prior art where, when the connection between the connecting post and the connecting hole becomes loose, the bottom end of the connecting post rigidly collides with the bottom of the connecting hole under the vibration of the speaker, generating additional noise and affecting the sound quality of the speaker.

[0005] This utility model provides a speaker, comprising: a cabinet; a speaker mounted on the cabinet, the speaker including a cone, the cabinet and / or the speaker having a connection hole located on the outer periphery of the cone; a grille disposed opposite to the speaker; and a connecting structure including a connecting post, a buffer, and a fastener, one end of the connecting post being disposed on the grille, the buffer being disposed at the end of the connecting post away from the grille, the buffer passing through the connection hole and engaging with the connection hole; wherein the buffer includes a connecting section and a buffer section, the connecting section being located at the end of the connecting post away from the grille, a first end of the fastener passing through the connecting section and detachably connected to the connecting post, and a second end of the fastener being located at the end of the connecting section away from the connecting post and having a gap between it and the bottom of the connection hole; the buffer section being made of an elastic material, one end of the buffer section being connected to the connecting section, and the other end of the buffer section protruding beyond the second end of the fastener toward the bottom of the connection hole.

[0006] Furthermore, the connecting section includes a connecting piece that abuts against the bottom of the connecting post near the connecting hole. The buffer section includes a buffer cylinder, one end of which is arranged in a ring around the periphery of the connecting section, and the other end of which extends toward the bottom of the connecting hole. The second end of the fastener is located inside the buffer cylinder.

[0007] Furthermore, the connecting piece and the buffer cylinder are integrally molded structures.

[0008] Furthermore, the length of the second end of the fastener along the axial direction of the connecting hole is set between 1.8 mm and 2.2 mm; and / or, the length of the end of the buffer section near the bottom of the connecting hole protruding from the second end of the fastener toward the bottom of the connecting hole is set between 0.4 mm and 0.6 mm.

[0009] Furthermore, the buffer also includes a positioning section made of elastic material. The positioning section is arranged in a ring around the outer periphery of the connecting post and is inserted into the connecting hole. The positioning cylinder is fixedly connected to the connecting section.

[0010] Furthermore, the positioning section includes a positioning cylinder, one end of which is integrally connected to the connecting section along its axial direction.

[0011] Furthermore, the ratio of the length of the positioning segment along the axis of the connecting hole to the length of the buffer segment along the axis of the connecting hole is set between 2.5 and 3; and / or, the length of the positioning segment along the axis of the connecting hole is greater than or equal to 6 mm.

[0012] Furthermore, the connecting hole has a limiting surface, which includes an arc-shaped surface that protrudes radially away from the axis of the connecting hole; the outer periphery of the positioning section is adapted to the contour of the limiting surface, and the positioning section and the limiting surface are matched to fix the connecting structure at the connecting hole.

[0013] Furthermore, multiple limiting surfaces are provided, and the multiple limiting surfaces are distributed at intervals along the circumference of the connecting hole; or, the hole wall of the connecting hole forms a limiting surface, and the limiting surface is arranged in a ring around the outer periphery of the positioning section along the circumference of the connecting hole.

[0014] 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 forms a limiting surface on the side facing the axial direction of the connecting hole.

[0015] Furthermore, the end of the limiting rib facing the opening of the connecting hole has a guide surface, which is inclined relative to the axis of the connecting hole to form a flared structure.

[0016] Furthermore, the connecting column and the mesh cover are integrally formed.

[0017] 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 transition section, and the outer diameter of the transition 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 first end of the fastener passes through the connecting section and is detachably connected to the end of the third section away from the transition section. A first reinforcing rib is provided at the connection position of the transition section and the second section.

[0018] 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.

[0019] Furthermore, the fixing ring includes an integrally formed body and a connecting protrusion. The body is arranged in a ring around the outer periphery of the cone, and the connecting protrusion is located on the side of the body facing the cabinet. A connecting hole is located on the connecting protrusion. And / or, one side of the cabinet has a mounting cavity and a mounting groove. The mounting groove is arranged in a ring at the opening of the mounting cavity and communicates with the mounting cavity. The cone is located in the mounting cavity, and the fixing ring is arranged in a ring at the mounting groove.

[0020] By applying the technical solution of this utility model, the rigid collision between the end of the connecting structure near the bottom of the connecting hole and the bottom of the connecting hole when the speaker vibrates strongly during music playback can be reduced, thus reducing additional noise and improving the sound quality of the speaker. Specifically, the connecting structure on the grille is engaged with the connecting hole via a buffer. The first end of the fastener passes through the connecting section of the buffer and connects to the end of the connecting post near the bottom of the connecting hole. The second end of the fastener is located at the end of the connecting section away from the connecting post and has a gap between it and the bottom of the connecting hole. One end of the buffer section, made of elastic material, is connected to the connecting section, and the other end protrudes from the second end of the fastener towards the bottom of the connecting hole. This arrangement allows the buffer section to absorb the vibration between the connecting structure and the connecting hole when the speaker vibrates strongly during music playback, preventing a rigid collision between the end of the connecting structure near the bottom of the connecting hole and the bottom of the connecting hole, thereby reducing additional noise and improving the sound quality stability of the speaker. Furthermore, this solution avoids rigid contact when the connecting post and the connecting hole are plugged in by using a buffer component, thereby further improving the stability of the connection structure and the connection hole.

[0038] 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.

[0039] like Figures 1 to 3 As shown, this utility model embodiment 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 cabinet 10 and / or the speaker, located on the outer periphery of the cone 20. The grille 40 is disposed opposite to the speaker. The connecting structure 50 includes a connecting post 51, a buffer 52, and a fastener 53. One end of the connecting post 51 is disposed on the grille 40, and the buffer 52 is disposed at the end of the connecting post 51 away from the grille 40. The buffer 52 passes through the connecting hole 30 and is inserted into the connecting hole 30. The buffer 52 includes a connecting... The fastener 521 consists of a connecting section 521 and a buffer section 522. The connecting section 521 is located at the end of the connecting post 51 away from the mesh cover 40. The first end of the fastener 53 passes through the connecting section 521 and is connected to the connecting post 51. The second end of the fastener 53 is located at the end of the connecting section 521 away from the connecting post 51 and has a gap between it and the bottom of the connecting hole 30. The buffer section 522 is made of elastic material. One end of the buffer section 522 is connected to the connecting section 521, and the other end of the buffer section 522 protrudes from the second end of the fastener 53 toward the bottom of the connecting hole 30.

[0040] By applying the technical solution of this utility model, the situation where the end of the connecting structure 50 near the bottom of the connecting hole 30 rigidly collides with the bottom of the connecting hole 30 when the speaker is playing music and generates strong vibrations can be reduced, thereby reducing the additional noise generated and improving the sound quality of the speaker.

[0041] Specifically, the connecting structure 50 on the grille 40 is inserted into the connecting hole 30 via a buffer 52. The first end of the fastener 53 passes through the connecting section 521 of the buffer 52 and is detachably connected to the end of the connecting post 51 near the bottom of the connecting hole 30. The second end of the fastener 53 is located at the end of the connecting section 521 away from the connecting post 51 and has a gap between it and the bottom of the connecting hole 30. One end of the buffer section 522, made of elastic material, is connected to the connecting section 521, and the other end protrudes from the second end of the fastener 53 towards the bottom of the connecting hole 30. This arrangement allows the buffer section 522 to absorb vibrations between the connecting structure 50 and the connecting hole 30 when the speaker vibrates strongly during music playback, preventing a rigid collision between the end of the connecting structure 50 near the bottom of the connecting hole 30 and the bottom of the connecting hole 30. This reduces additional noise and improves the sound quality stability of the speaker enclosure. Furthermore, this solution uses the buffer 52 to connect with the connecting hole 30, which avoids wear and loosening that may occur between the connecting post 51 and the connecting hole 30 under long-term use or strong vibration, thus enhancing the stability and durability of the speaker grille 40 installation.

[0042] In this embodiment, the connecting segment 521 includes a connecting piece that abuts against the bottom of the connecting post 51 near the connecting hole 30. Furthermore, the projection of the end face of the connecting post 51 near the bottom of the connecting hole 30 onto the connecting piece is located within the connecting piece. Specifically, the connecting segment 521 has a circular, plate-like structure. This design increases the contact area between the connecting piece and the connecting post 51, thereby improving the stability of the abutment between them.

[0043] Furthermore, the buffer section 522 includes a buffer cylinder. One end of the buffer cylinder is arranged in a ring around the periphery of the connecting section 521 along its axial direction, and the other end of the buffer cylinder extends towards the bottom of the connecting hole 30. The second end of the fastener 53 is located inside the buffer cylinder. It can be understood that since the second end of the fastener 53 is located inside the buffer cylinder, even if the buffer cylinder contacts the bottom of the connecting hole 30, it is only the periphery of the bottom of the buffer cylinder that contacts the bottom of the connecting hole, further improving the buffering effect of the buffer component.

[0044] In this embodiment, the fastener 53 is a metal screw. The shank portion of the fastener 53 forms the first end of the fastener 53, and the nut portion of the fastener 53 forms the second end of the fastener 53.

[0045] In this design, the length 'a' of the second end of the fastener 53 along the axial direction of the connecting hole 30 is set between 1.8 mm and 2.2 mm.

[0046] It is understood that, in the embodiments of this solution, the length 'a' of the nut portion of the fastening screw along the axial direction can be specifically set to 1.8mm, 2mm, or 2.2mm, etc.; preferably, it is set to 2mm.

[0047] Furthermore, along the axial direction of the connecting hole 30, the length of the buffer section 522 protruding from the end face of the second end of the fastener 53 towards the bottom of the connecting hole 30 is b, and b is set between 0.4mm and 0.6mm. Specifically, it can be set to 0.4mm, 0.5mm or 0.6mm; preferably it can be set to 0.5mm.

[0048] If the length of the buffer section 522 protruding from the second end face of the fastener 53 towards the bottom of the connecting hole 30 is too long, it will easily lead to waste of material in the buffer section 522 and may cause deformation due to its excessive length. If the length of the buffer section 522 protruding from the second end face of the fastener 53 towards the bottom of the connecting hole 30 is too short, the second end of the fastener 53 may come into contact with the bottom of the connecting hole 30, generating noise. In summary, this solution sets the length of the buffer section 522 protruding from the second end face of the fastener 53 towards the bottom of the connecting hole 30 within the above-mentioned range, which can ensure the buffering effect of the buffer section 522 while avoiding waste of material in the buffer section 522.

[0049] In this embodiment, the connecting piece is also made of elastic material, and the connecting piece and the buffer cylinder are integrally formed. This design improves the stability of the connection between the connecting piece and the buffer cylinder.

[0050] Specifically, the buffer 52 also includes a positioning section 523, which is made of elastic material. The positioning section 523 is arranged in a ring around the outer periphery of the connecting post 51 and is inserted into the connecting hole 30. The positioning cylinder is fixedly connected to the connecting section 521. It can be understood that the positioning section 523, made of elastic material, is inserted into the connecting hole 30, avoiding hard contact between the connecting structure 50 and the connecting hole 30, thereby reducing noise generation and improving the sound purity of the speaker; it also reduces connection instability or loosening caused by improper installation.

[0051] Specifically, the positioning section 523 includes a positioning cylinder, one end of which is integrally connected to the connecting section 521 along its axial direction. This means that the axial end of the positioning cylinder is integrally connected to the periphery of the connecting piece. This configuration makes the entire buffer component 52 a single integrated structure, reducing assembly errors, improving the ease of processing the buffer component 52, and enhancing its structural strength.

[0052] The ratio of the length c of the positioning section 523 along the axis of the connecting hole 30 and the length d of the buffer section 522 along the axis of the connecting hole 30 can be set between 2.5 and 3. Specifically, it can be set to 2.5, 2.6, 2.7 or 3.

[0053] It is understood that the length d of the buffer segment 522 along the axis of the connecting hole 30 is equal to a + b. In this embodiment, the length of the positioning segment 523 along the axis of the connecting hole 30 is greater than the length of the buffer segment 522 along the axis of the connecting hole 30. This arrangement ensures the rationality of the buffer component 52 structure, enabling the buffer segment 522 to have a buffering effect, ensuring the stability of the insertion of the positioning segment 523 into the connecting hole 30, and reducing the waste of buffer component 52 material.

[0054] Furthermore, in this scheme, the length of the positioning section 523 along the axial direction of the connecting hole 30 is greater than or equal to 6mm; the length of the buffer section 522 along the axial direction of the connecting hole 30 can be specifically set to 6mm, 6.5mm or 7mm, etc.

[0055] like Figure 3 and Figure 4 As shown, the connecting hole 30 further includes a limiting surface 301, which comprises an arc-shaped surface that protrudes radially away from the axis of the connecting hole 30. The outer circumferential surface of the positioning cylinder is adapted to the contour of the limiting surface 301, and the positioning cylinder and the limiting surface 301 are matched to fix the connecting structure 50 at the connecting hole 30. This configuration can further improve the stability of the connection process between the connecting structure 50 and the connecting hole 30, reduce the vibration of the grille 40 caused by loosening of the connection between the connecting structure 50 and the connecting hole 30, and reduce the possibility of deterioration in the sound quality of the speaker.

[0056] 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 arrangement allows the buffer 52 to extend into the connecting hole 30 under the action of extrusion force. The limiting surface 301 restricts the movement of the positioning cylinder in the axial direction of the connecting hole 30 by limiting the movement of the connecting structure 50 in the axial direction of the connecting hole 30. The arc-shaped design of the limiting surface 301, combined with the characteristics of the positioning cylinder made of elastic material, can generate sufficient friction to limit the position of the connecting structure 50 in the radial direction.

[0057] In this embodiment of the solution, the outer circumferential surface of the positioning cylinder is similar to the circumferential shape of the middle part of an ellipsoid along the axial direction of its major axis.

[0058] Furthermore, in this design, the positioning cylinder, connecting piece, and buffer cylinder are coaxially arranged, and the outer diameters of the end of the positioning cylinder connected to the connecting piece, the connecting piece, and the buffer cylinder are all the same. This arrangement improves the smoothness of the insertion of the buffer component 52 into the connecting hole 30.

[0059] This solution does not specify the exact form of the limiting surface 301.

[0060] In some embodiments of this solution, the wall of the connecting hole 30 forms a limiting surface 301, which is circumferentially arranged around the outer periphery of the positioning section 523. That is, the contour of the connecting hole 30 matches the contour of the outer peripheral surface of the positioning cylinder.

[0061] 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 allows the positioning cylinder to contact and establish a limiting relationship with the multiple limiting surfaces 301 during the insertion of the buffer 52 into the connecting hole 30, thereby improving the smoothness of the insertion process of the buffer 52.

[0062] Specifically, a plurality of limiting ribs 31 are provided in the connecting hole 30. The plurality of 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 forms a limiting surface 301 on the side facing the axial direction of the connecting hole 30. Furthermore, there is a gap between the limiting surface 301 and the bottom of the connecting hole 30. This arrangement facilitates the processing and forming of the limiting ribs 31.

[0063] The above configuration creates a recess between two adjacent limiting ribs 31. This configuration allows the recess to accommodate the deformation of the buffer 52 when it is inserted into the connecting hole 30, further improving the smoothness of the buffer 52's insertion into the connecting hole 30.

[0064] Furthermore, each limiting rib 31 has a mating surface on one side facing the axis of the connecting hole 30. The mating surface is located at the end of the limiting surface 301 near the bottom of the connecting hole 30. The mating surface is arc-shaped, and its contour matches the contour of the outer circumferential surface of the buffer cylinder. This design ensures that the outer circumferential surface of the buffer cylinder fits snugly with the mating surface, further improving the stability of the insertion of the buffer member 52 into the connecting hole 30.

[0065] Furthermore, the end of the limiting rib 31 facing the opening of the connecting hole 30 also has a guide surface 311, which 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 buffer 52 during insertion into the connecting hole 30, further improving the smoothness of the insertion of the buffer 52 into the connecting hole 30.

[0066] 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.

[0067] like Figure 5 and Figure 6 As shown in the embodiment of this solution, the grille 40 and the connecting post 51 are integrally molded. This design improves the stability of the connection between the connecting post 51 and the grille 40. The integrally molded connecting post 51 and the grille 40 are assembled during the production stage, simplifying the final speaker assembly process. During assembly, no additional steps are required to fix the connecting post 51 and the grille 40.

[0068] In this embodiment, the mesh cover 40 and the connecting post 51 are formed by injection molding.

[0069] In this embodiment, the connecting post 51 includes a first segment 511, a transition segment 512, and a second segment 513 connected sequentially along the axial direction. The outer diameter of the first segment 511 is larger than that of the transition segment 512, and the outer diameter of the transition segment 512 is larger than that of the second segment 513. The outer diameter of the transition segment 512 gradually decreases from the first segment 511 to the second segment 513. The first segment 511 is a hollow structure. The end of the first segment 511 away from the transition segment 512 is integrally connected to the mesh cover 40. The positioning sleeve is fitted onto the second segment 513. The first end of the fastener 53 passes through the connecting segment 521 and is detachably connected to the end of the second segment 513 away from the transition segment 512. This configuration improves the convenience of the injection molding process of the mesh cover 40 and the connecting post 51. Furthermore, it saves injection molding materials while improving the connection strength between the connecting post 51 and the mesh cover 40, as well as the structural strength of the connecting post 51 itself.

[0070] Furthermore, the first segment 511 is located on the outer side of the connecting hole 30 along its axial direction, and there are gaps between the grille 40 and the surface of the cone, as well as between the grille 40 and the surface of the cabinet 10. This arrangement can reduce the vibration that occurs when the grille 40 contacts the cone or the cabinet 10 during cone vibration, thereby further improving the sound quality of the speaker.

[0071] Furthermore, a first reinforcing rib is provided at the connection point between the transition section 512 and the second section 513. The provision of the first reinforcing rib can improve the connection strength at the connection point between the transition section 512 and the second section 513, and improve the overall structural strength of the connecting column 51.

[0072] Specifically, the end face of the second segment 513 furthest from the transition segment 512 is provided with a threaded hole, which is fastened to a fastening screw. The metal fastening screw improves the stability of the connection between the buffer 52 and the connecting post 51.

[0073] In some embodiments of this solution, the connection hole 30 is provided on the housing 10.

[0074] like Figures 5 to 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 and fixedly mounted on the enclosure 10. A connecting hole 30 is located on the fixing ring 60. The fixing ring 60 provides an additional support point for the loudspeaker, avoiding the instability that might result from a direct connection between the cone 20 and the enclosure 10. The connecting hole 30 is located on the fixing ring 60, facilitating the machining of its internal structure.

[0075] Furthermore, 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 machining of the connecting hole 30.

[0076] 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.

[0077] like Figure 2 and Figure 3 As 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.

[0078] 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.

[0081] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0083] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0084] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
