[0067] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.
[0068] Figure 1 is a schematic diagram of the first form of vibration reduction structure 1 provided in the embodiment of the present application, see Figure 1 As shown, in one or more embodiments, the present application provides a vibration reduction structure 1, which includes: a vibration reduction unit 10; the vibration reduction unit 10 includes: a plurality of contact parts 100 and an elastic part 200; the contact part 100 has a contact surface 101; the elastic part 200 can undergo elastic deformation, and the plurality of contact parts 100 are respectively connected to the elastic part 200, and the connection between the contact part 100 and the elastic part 200 forms a connecting edge 209; wherein the contact surface 101 extends along the length direction of the connecting edge 209. In at least one embodiment, the present application utilizes the contact portion 100 of the vibration reduction unit 10 to contact the vibration component (such as a speaker or a motor) and other components, and utilizes the elastic portion 200 to separate the vibration component from other components, so that the elastic portion 200 can undergo elastic deformation to buffer the vibration of the vibration component, thereby achieving a non-rigid connection between the vibration component and the isolated parts or components, preventing the isolated vibration parts or components from being disturbed or damaged by the vibration component, thereby reducing or avoiding the occurrence of resonance, and further facilitating the structural stability of the equipment (for example, a speaker or conferencing equipment) where the vibration component is located, and extending its service life; in addition, the vibration reduction unit 10 of the present application has an overall strip-shaped structure, which can help reduce the occupied space, and has the characteristics of a wide range of applications and good vibration reduction effect.
[0069] In some embodiments, for ease of description, the length direction of the connecting edge 209 is recorded as AA direction. The number of vibration damping units 10 in the vibration damping structure 1 may be one or more, and the number of vibration damping units 10 may be 2 or more, such as 2 or 3, etc., which is not specifically limited in the present application; and the number of contact portions 100 in the vibration damping unit 10 may be 2 or more, etc., which may be specifically designed according to actual needs. The number of elastic portions 200 may be 1 or more, and when the number of elastic portions 200 is multiple, the number may be 2 or more, which may be specifically designed according to actual needs. The elastic portion 200 has two connecting sides that are arranged opposite to each other, and each connecting side is connected to the contact portion 100, so that the elastic portion 200 can be used as an intermediate structure for buffering. The connection between the contact portion 100 and the elastic portion 200 forms a connecting edge 209, which may be a straight line. For example, as Figure 1 As shown, there are two contact portions 100 , one elastic portion 200 , and the elastic portion 200 is located between two contact portions 100 that are spaced apart.
[0070] In some embodiments, the areas of the cross sections of the shock absorbing unit 10 perpendicular to the length direction of the connecting edge 209 are equal, so that the shock absorbing unit 10 with equal cross-sectional area is formed, so that the extrusion molding process can be used for production. The extrusion molding process has the characteristics of high production efficiency, and the equipment used in the extrusion molding process is relatively simple, and its production yield is high, so that the comprehensive production cost of the shock absorbing structure is low. In addition, the shock absorbing unit 10 is produced by the extrusion molding process, so that its length size can be changed more flexibly, so that it is suitable for shock absorption in different scenarios.
[0071] Figure 2 yes Figure 1 The main view of Figure 2 As shown, in some embodiments, the contact surface 101 is a plane, so that when the object contacted by the contact surface 101 is a plane, it can adapt to the contacted object, thus ensuring the stability of the installation of the vibration reduction structure 1.
[0072] Combination Figure 1 and Figure 2 As shown, in some embodiments, the length direction of the elastic part 200 is parallel to the length direction of the connecting edge 209, and the cross section of the elastic part 200 perpendicular to the length direction of the elastic part 200 is a first cross section 201; wherein, the first cross section 201 is a quadrilateral, which is convenient for manufacturing, and by optimizing the cross-sectional design, the deformation of the structure can be reasonably controlled while ensuring the rigidity of the structure, so that the structure can maintain a stable shape and performance when subjected to external forces. Exemplarily, the quadrilateral can be a parallelogram, a rectangle or a square, and can be specifically designed according to actual needs.
[0073] Figure 3 is a schematic diagram of a second form of a vibration reduction structure 1 provided in an embodiment of the present application, Figure 4 is a schematic diagram of a third form of vibration reduction structure provided in an embodiment of the present application; see Figure 3 and Figure 4 As shown, in some other possible implementations, the contact surface 101 may be a curved surface, so that when the object contacted by the contact surface 101 is a curved surface, it can adapt to the surface of the contacted object, thus ensuring the stability of the installation of the vibration reduction structure 1. For example, the curved surface is a cylindrical surface, see Figure 3 As shown, when the contact surface 101 is a curved surface, the curved surface is concave in the direction where the elastic part 200 is located, which not only ensures the stability of the installation of the vibration reduction structure 1, but also has a larger area than the contact surface 101 is a flat surface, so when it contacts with an object, the contact surface 101 and the object can have a larger contact area. Figure 4 As shown, the curved surface may also protrude in the direction opposite to the elastic portion, so that the curved surface may also match the surface of the object in contact, thereby ensuring the stability of the installation of the vibration reduction structure 1. It is understandable that in some other possible implementations, all contact surfaces 101 in the vibration reduction unit 10 may be planes or curved surfaces, or a portion of the contact surfaces 101 may be curved surfaces and a portion of the contact surfaces 101 may be planes. The specific shape of the contact surface 101 may be determined by the shape of the surface of the object in contact, and this application does not make any specific limitation.
[0074] Figure 5 is a schematic diagram of a third form of vibration reduction structure 1 provided in an embodiment of the present application, see Figure 5 As shown, in some embodiments, a first protrusion 102 is provided on the contact surface 101, so that when there is a depression on the object contacted by the contact surface 101, it can be matched with it, thereby improving the stability of the installation of the vibration damping structure 1 and preventing the vibration damping structure 1 from slipping during use. It can be understood that in some other possible implementations, a concave groove can also be provided on the contact surface 101, so that when there is a protrusion on the object contacted by the contact surface 101, it can be matched with it, thereby improving the stability of the installation of the vibration damping structure 1 and preventing the vibration damping structure 1 from slipping during use. Of course, the first protrusion 102 and the concave groove can also be provided on the contact surface 101 at the same time to respectively match the depression and the protrusion on the object contacted by the contact surface 101, thereby improving the stability of the installation of the vibration damping structure 1 and preventing the vibration damping structure 1 from slipping during use; and the number of the first protrusion 102 and the concave groove can be determined according to the number of depressions and / or protrusions on the contacted object, such as 1 or more, etc., and this application does not make specific limitations.
[0075] Figure 6 is a schematic diagram of a fourth type of vibration reduction structure 1 provided in an embodiment of the present application, Figure 7 yes Figure 6 The main view of Figure 6 and Figure 7 As shown, in some embodiments, the elastic part 200 has two opposite first surfaces 202, and the first surface 202 is provided with a second protrusion 203, and the second protrusion 203 is in a spherical crown shape, so that the elastic part 200 can be optimized in terms of stiffness, stress distribution and other characteristics, and the second protrusion 203 can be used as a reinforcing rib to enhance the structural strength of the elastic part 200 in a specific direction. Exemplarily, the number of the second protrusions 203 can be one or more, and when the number of the second protrusions is multiple, they are spaced and distributed along the length direction of the elastic part 200, for example, the number of the second protrusions 203 on the first surface 202 is 2, 3 or 4, and of course it can also be determined according to actual conditions, and this application does not make specific restrictions; when the elastic part 200 is deformed, the second protrusion 203 can also be elastically deformed together with the elastic part 200, so that the second protrusion 203 can disperse the stress concentration, reduce the risk of the elastic part 200 being broken due to external force, and thus improve the durability of the elastic part 200.
[0076] Figure 8 is a schematic diagram of the fifth form of vibration reduction structure 1 provided in the embodiment of the present application, see Figure 8 As shown, in other embodiments, the edge profile 2011 of the first cross-section 201 is arc-shaped, which can optimize the stiffness, stress distribution and other characteristics of the elastic part 200 and enhance the structural strength of the elastic part 200 in a specific direction; exemplarily, the first cross-section 201 has two arc-shaped edge profiles 2011, and the directions in which the two arc-shaped edge profiles 2011 protrude are opposite to each other. This design helps to improve the stress distribution and enhance the overall durability of the elastic part 200.
[0077] Fig. 9 is a schematic diagram of the sixth form of the vibration reduction structure 1 provided in the embodiment of the present application, see Fig. 9 As shown, in some other embodiments, the edge profile 2011 of the first cross-section 201 is arc-shaped, so that the stiffness, stress distribution and other characteristics of the elastic part 200 can be optimized, and the structural strength of the elastic part 200 in a specific direction can be enhanced; exemplarily, the first cross-section 201 has two arc-shaped edge profiles 2011, and the protruding directions of the two arc-shaped edge profiles 2011 are arranged in opposite directions. This design helps to improve the stress distribution and enhance the overall durability of the elastic part 200.
[0078] Fig.10 is a schematic diagram of a seventh type of vibration reduction structure 1 provided in an embodiment of the present application, Fig.11 yes Fig.10 The main view, combined with Fig.10 and Fig.11 As shown, in some embodiments, the vibration reduction unit 10 includes two or more elastic parts 200; in the vibration reduction unit 10, multiple elastic parts 200 are located between two contact parts 100 arranged at intervals, so that the multiple elastic parts 200 can increase the rigidity and improve the service life of the vibration reduction structure 1. Exemplarily, the number of contact parts 100 is two, one of the connecting sides of the elastic part 200 is connected to one of the contact parts 100, and the other connecting side of the elastic part 200 is connected to another contact part 100; the multiple elastic parts 200 are arranged at intervals. In the vibration reduction unit 10, two adjacent elastic parts 200 and two contact parts 100 surround a deformation cavity 208, so that when the elastic part 200 undergoes elastic deformation, it can have a certain deformation space.
[0079] In some embodiments, the surface of the elastic part 200 facing the deformation cavity 208 is the first inner surface 204, and the surface of the elastic part 200 facing away from the deformation cavity 208 is the first outer surface 205. The first outer surface 205 is a plane, a curved surface convex to the outside of the deformation cavity 208, or a curved surface convex to the inside of the deformation cavity 208; the first inner surface 204 is a plane, a curved surface convex to the outside of the deformation cavity 208, or a curved surface convex to the inside of the deformation cavity 208. In this way, by designing the shapes of the first inner surface 204 and the first outer surface 205 of the elastic part 200, the overall durability of the vibration reduction unit 10 can be ensured.
[0080] In one embodiment, see Fig.11 As shown, the first outer surface 205 is a curved surface convex to the outside of the deformation cavity 208; the first inner surface 204 is a curved surface convex to the outside of the deformation cavity 208, which can improve the overall durability of the vibration reduction unit 10.
[0081] Fig.12 is a schematic diagram of the eighth form of the vibration reduction structure 1 provided in the embodiment of the present application, see Fig.12 As shown, in yet another embodiment, the first outer surface 205 is a curved surface convex toward the outside of the deformation cavity 208 , and the first inner surface 204 is a plane, which can improve the overall durability of the vibration reduction unit 10 .
[0082] Fig.13 is a schematic diagram of a ninth form of a vibration reduction structure 1 provided in an embodiment of the present application, see Fig.13 As shown, in another embodiment, the first outer surface 205 is a curved surface convex toward the inside of the deformation cavity 208; the first inner surface 204 is a curved surface convex toward the inside of the deformation cavity 208, which can improve the overall durability of the vibration reduction unit 10.

[0084] It is understandable that in the examples of this application, only Figures 11 to 14 There are four forms of elastic parts 200 in the embodiment. Of course, in some other possible implementations, the first outer surface 205 and the first inner surface 204 can also be combined to form other types of elastic parts 200, which will not be described in detail in the embodiments of the present application.

Exemplarily, each connecting strip 207 is connected to a contact portion 100, so that the circumference of the elastic part 200 has a plurality of contact portions 100, so that the vibration reduction unit 10 can adapt to more complex installations; the number of connecting strips 207 can be 2, 3, 4 or more, such as Fig.14 and Fig.15 As shown, the number of the connecting strips 207 is 4. The hollow cavity of the tubular structure 206 is in the form of a cylinder, which is beneficial to improving the overall durability of the vibration reduction unit 10.
[0086] Fig.17 It is a schematic diagram of the twelfth form of vibration damping structure 1 provided in an embodiment of the present application; in some embodiments, the number of vibration damping units 10 is multiple, and the multiple vibration damping units 10 are detachably connected to each other; illustratively, a limiting slot 104 is provided on one end face of the contact portion 100 along the length direction of the connecting edge 209, and a limiting boss 105 is provided on the other end face. When the multiple vibration damping units 10 are spliced together, the limiting boss 105 of one vibration damping unit 10 is inserted into the limiting slot 104 of another vibration damping unit 10, thereby realizing that multiple vibration damping units are connected together, which can increase the length of the vibration damping structure 1 to meet different application scenarios.
[0087] In some embodiments, the elastic portion 200 and the contact portion 100 are an integral structure, which can increase the overall structural stability of the vibration reduction unit 10. For example, the elastic portion 200 and the contact portion 100 are made by an integral molding process.
[0088] In some embodiments, the elastic portion 200 is made of silicone, rubber, polyethylene terephthalate or thermoplastic polyurethane elastomer, which can meet different application scenarios.

It should be noted that in some other possible implementations, the material of the contact part 100 and the material of the elastic part 200 can also be made of different materials, for example, the contact part 100 directly uses a rigid material, such as metal, and the elastic part 200 is made of an elastic material, and the contact part 100 and the elastic part 200 are connected by insert injection molding.
[0090] In some embodiments, the contact portion 100 also includes an embedding piece (not shown), which is buried in the contact body 103; the embedding piece is made of metal, and the contact portion 100 can be used to improve the overall stiffness of the contact portion 100 and reduce its deformation; illustratively, the metal can be iron, stainless steel or copper, the contact portion 100 is a plate-like structure, and the embedding piece is a plate-like structure. When manufacturing the vibration damping unit 10, the embedding piece is embedded in the interior of the contact body 103 through an insert injection molding process.
