[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art.

In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0036] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower".

[0037] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" are used merely as labels and are not intended to limit the quantity of their objects.

[0038] The present disclosure provides a terminal device, such as Figure 1 As shown, the terminal device includes a housing, a vibration component and a buffer connector 03, wherein:

[0039] The shell can be used to install the vibration component, the buffer connector 03 and other components. In order to fix the vibration component, the shell can be provided with a positioning column 011, and the positioning column 011 can be connected to the vibration component through the buffer connector 03.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments of the present disclosure, the housing may include a carrier plate 01, and a positioning column 011 may be disposed on the carrier plate 01. The positioning column 011 may be a cylindrical or prism structure, or a truncated cone or prism structure that shrinks in a direction away from the carrier plate 01. The positioning column 011 and the carrier plate 01 may be an integral structure, or may be an independent structure connected by means of clamping, threading, bonding, etc.

[0041] Further, such as Figure 1 , Figure 2 and Figure 4 As shown, in order to improve the stability of the positioning column 011, a plurality of ribs 012 can be arranged on the periphery of the positioning column 011, and each rib 012 is distributed around the circumference of the positioning column 011, and all are connected to the bearing plate 01, so that the positioning column 011 can be supported by the ribs 012 to prevent it from breaking, falling off, and other problems. The ribs 012 can shrink in the direction away from the bearing plate 01, that is, the area of ​​one end close to the bearing plate 01 is larger than the area of ​​one end of the original bearing plate 01, thereby improving stability. At the same time, the ribs 012, the positioning column 011 and the bearing plate 01 can be an integral structure so that they can be formed simultaneously by the same process. For example, the ribs 012, the positioning column 011 and the bearing plate 01 are all made of plastic and can be formed simultaneously by an injection molding process. The number of the positioning columns 011 can be one, two or more, and the specific number is not specifically limited here. The above-mentioned ribs 012 can be arranged on the periphery of each positioning column 011.

[0042] In addition, the housing may further include a shielding cover, which is a hollow structure with at least one open end. The shielding cover may be covered on the carrier plate 01, and together with the carrier plate 01, a hollow housing is formed. The positioning column 011, the vibration assembly, and the buffer connector 03 are located inside the shielding cover. The shielding cover may be a polyhedral structure surrounded by a plurality of flat plates, or may be a cylindrical structure or other structures, which are not specifically limited here; of course, the present disclosure does not exclude the embodiment in which the housing only includes the carrier plate 01.

[0043] like Figure 1-Figure 4 As shown, the vibration component can be arranged on the housing, for example, the vibration component can be arranged on the carrier plate 01 and is located inside the housing. The vibration component can be a speaker component, which will generate vibration when it makes a sound. Of course, it can also be other components that can cause vibration, such as a motor, which are not listed here one by one. The buffer connector 03 can be sleeved on the positioning column 011 and connected to the vibration component, so that the vibration component is fixed to the housing through the buffer connector 03.

[0044] like Figure 1-Figure 4 As shown, in some embodiments of the present disclosure, the vibration assembly includes a housing 02 and a lug 022 connected to the outer side of the housing 02, the lug 022 is an annular structure with a notch, that is, the lug 022 is an incompletely closed annular structure, and the buffer connector 03 can be inserted into the lug 022, that is, the lug 022 surrounds the buffer connector 03. At the same time, in order to reduce the buffer connector 03 from sliding out of the notch of the lug 022, the width of the notch can be made smaller than the maximum width of the buffer connector 03 in the radial direction of the lug 022.

[0045] Further, such as Figure 1 and Figure 2As shown, in some embodiments, the surface of the housing 02 may be recessed inward to form an avoidance groove 023 that runs through in a direction perpendicular to the bearing plate 01, and at least a portion of the lug 022 is located in the avoidance groove 023. The avoidance groove 023 can accommodate at least a portion of the buffer connector 03, that is, the buffer connector 03 is avoided to prevent it from protruding too much from the surface of the housing 02, which is conducive to saving space. The number of avoidance grooves 023 can be the same as the number of lugs 022, or it can be less than the number of lugs 022, that is, the avoidance groove 023 can also be not provided at the position where the lug 022 is provided.

[0046] like Figure 1 , Figure 2 and Figure 5 As shown, the buffer connection member 03 may include a plurality of concentrically distributed buffer rings 1, that is, the buffer rings 1 are arranged around in sequence, and in two adjacent buffer rings 1, the outer buffer ring 1 surrounds the inner buffer ring 1, and there is a gap between the two. The axial heights of different buffer rings 1 may be the same or different. In some embodiments of the present disclosure, the buffer ring 1 may be a closed annular structure, but its contour is not limited to a circle, and may also be a rectangle or other polygon, or may be an ellipse, a round shape, or the like. At the same time, the shapes of the contours of different buffer rings 1 may be the same or different. In other embodiments of the present disclosure, the buffer ring 1 may also be an incompletely closed annular structure with a cutout, and if there are multiple buffers with a cutout, the cutouts may be staggered to avoid the cutouts being aligned in the axial direction, resulting in too low strength in the area where the cutouts are located.

[0047] The innermost one of the buffer rings 1 is a central buffer ring 11, and the outermost one is an edge buffer ring 12. The number of buffer rings 1 can be two, three or more. If the number of buffer rings 1 is two, only one is the central buffer ring 11 and the other is the edge buffer ring 12. If the number of buffer rings 1 is greater than two, at least one buffer ring 1 is provided between the central buffer ring 11 and the edge buffer ring 12.

[0048] A support structure 2 connecting the two buffer rings 1 is provided between two adjacent buffer rings 1, so that the buffer rings 1 are connected into a whole through the support structure 2. The support structure 2 does not completely fill the space between the two adjacent buffer rings 1, so that its rigidity can be lower than that of the buffer ring 1, and thus has a certain elasticity, so that the two adjacent buffer rings 1 can move relative to each other.

[0049] like Figure 1-Figure 4As shown, the central buffer ring 11 is sleeved outside the positioning column 011, and the inner wall of the central buffer ring 11 can fit with the positioning column 011, so that the central buffer ring 11 is confined on the shell of the terminal device. The outer side of the edge buffer ring 12 is provided with a limiting structure that cooperates with the vibration component, and the limiting structure cooperates with the vibration component, so that the vibration component is confined on the shell through the buffer ring 1 and the positioning column 011; and due to the existence of the support structure 2 with a lower stiffness than the buffer ring 1, adjacent buffer rings 1 can move relative to each other, so that the vibration can be weakened during the transmission process through multiple buffer rings 1 and support structures 2, which is conducive to reducing noise and can reduce the impact on other components caused by resonance in the terminal device.

[0050] The axial height of the center buffer ring 11 can be greater than that of the edge buffer ring 12, so that its two ends can extend out of the two ends of the edge buffer ring 12, which is beneficial to increase the range of its sleeve on the positioning column 011 and improve the positioning effect.

[0051] like Figure 1 , Figure 2 and Figure 4 As shown, the axial height of the central buffer ring 11 is not greater than the height of the positioning column 011, and if a rib plate 012 is provided on the outside of the positioning column 011, the height of the rib plate 012 is less than the height of the positioning column 011, so that at least part of the area of ​​the positioning column 011 does not have the rib plate 012, and the central buffer ring 11 can be sleeved in the area and abut against the top of the rib plate 012, and the rib plate 012 can play a supporting role. Furthermore, the top of the rib plate 012 can be set as a flat structure and fit with the central buffer ring 11.

[0052] In addition, if Figure 1-Figure 4 As shown, in order to position in the axial direction, the terminal device may also include a positioning screw 04, which has a threaded portion 041 and a screw head 042 located at one end of the threaded portion 041. The positioning column 011 has an axially extending threaded hole. The threaded portion 041 can be inserted into the threaded hole of the positioning column 011 and is threadedly connected to the positioning column 011. At the same time, the radial dimension of the screw head 042 is larger than the threaded portion 041, and larger than the radial dimension of the positioning column 011, so that it is at least crimped on the surface of the central buffer ring 11 on the principle carrier plate 01, thereby preventing the buffer connector 03 from moving axially. Of course, more buffer rings 1 can also be crimped, but in order to avoid compressing the deformation space of the buffer connector 03 due to the limitation of the screw head 042, the screw head 042 can only be crimped on at least a part of the central buffer ring 11, and does not extend to the buffer ring 1 outside the central buffer ring 11.

[0053] The buffer connection piece 03 is described in detail below:

[0054] As mentioned above, the support structure 2 does not completely fill the gaps between the buffer rings 1, for example:

[0055] like Figure 2-Figure 5 As shown, the support structure 2 includes support bars 21, the number of which can be one, two, three or more, and the specific number is not particularly limited here. Two adjacent buffer rings 1 are connected to the support bars 21, that is, one end of the support bar 21 is connected to the inner buffer ring 1, and the other end of the support bar 21 is connected to the outer buffer ring 1.

[0056] In some embodiments, there are multiple support bars 21 between two adjacent buffer rings 1, and each support bar 21 can be radially distributed along the circumference of the buffer ring 1, so that uniform force can be achieved while connecting adjacent buffer rings 1. In addition, each support bar 21 can be radially distributed with the central axis of the axial extension of the central buffer ring 11 as the axis, so that the support bar 21 can extend in the radial direction of the central buffer ring 11, but the support bar 21 can also extend in a direction that is at a certain angle to the radial direction, so that the extension line of the support bar 21 does not pass through the central axis of the central buffer ring 11.

[0057] Further, such as Figure 2-Figure 5 As shown, the support bar 21 may be a polyhedral structure, which may be surrounded by a plurality of side surfaces simultaneously connected to two adjacent buffer rings 1, and at least two side surfaces of each side surface are arranged opposite to each other. In two adjacent buffer rings 1 and the support bar 21 between them, the distance between the two oppositely arranged side surfaces of at least one support bar 21 decreases or increases toward one buffer ring 1, so that the support bar 21 shrinks or expands toward the buffer ring 1 connected to it, that is, the size is uneven, thereby enhancing the unevenness of the force on the support bar 21 itself, which is beneficial to improving elasticity while ensuring the connection function, and is beneficial to improving the buffering effect.

[0058] In addition, the elasticity of the support bar 21 can be improved by opening a through hole or a groove. The support bar 21 can also be set as a curved bar structure, which can extend along an arc-shaped, wavy, or broken line-shaped trajectory, which is conducive to improving flexibility.

[0059] In some embodiments, a plurality of support bars 21 are provided between two adjacent buffer rings 1, and the support bars 21 are rod-shaped structures. Among the support bars 21 between two adjacent buffer rings 1, at least two support bars 21 cross in space but do not touch, that is, the orthographic projections of at least two support bars 21 on the supporting plate 01 intersect.

[0060] In other embodiments of the present disclosure, the entire support structure 2 may be an annular structure and may be disposed between two adjacent buffer rings 1. At the same time, the support structure 2 may adopt a porous structure to make it elastic.

[0061] like Figure 1-Figure 5As shown, the limiting structure can be used to connect the vibration assembly. In some embodiments of the present disclosure, the limiting structure is a limiting groove 121 provided on the outer peripheral surface of the edge buffer ring 12. The limiting groove 121 can be annular and extend along the circumference of the edge buffer ring 12. The width of the limiting groove 121 is less than the height of the edge buffer ring 12, and the depth of the limiting groove 121 is less than the thickness of the edge buffer ring 12, so as to avoid cutting off the edge buffer ring 12. The width of the limiting groove 121 is the distance between the two side walls distributed along the axial direction. The edge buffer ring 12 can be inserted into the lug 022, and the lug 022 is matched in the limiting groove 121. The thickness of the annular lug 022 in its axial direction is less than the width of the limiting groove 121. The edge buffer ring 12 can slide from the notch of the lug 022 into the annular range of the lug 022. The edge of the lug 022 is located in the limiting groove 121, so that the position of the lug 022 is limited by the limiting groove 121, and then the position of the vibration assembly is limited.

[0062] In some embodiments of the present disclosure, a groove may be provided on the inner wall of the avoidance groove 023 of the outer shell 02 of the vibration assembly, and a ridge may be provided on the outer periphery of the edge buffer ring 12, which may be engaged in the groove to achieve positioning.

[0063] Furthermore, at least one of the inner wall of the central buffer ring 11 and the inner surface of the limiting groove 121 may be provided with a protrusion, a depression, an opening or the like to reduce the contact surface between the central buffer ring 11 and the positioning column 011 so as to facilitate the movement and achieve buffering. For example:

[0064] like Figure 5 As shown, in some embodiments of the present disclosure, the inner wall of the center buffer ring 11 may be provided with a plurality of first protrusions 111. The first protrusions 111 may be structures such as a hemisphere, a spherical segment, a truncated cone, a prism, etc., as long as they protrude from the inner wall of the center buffer ring 11. The first protrusions 111 may be an integral structure with the center buffer ring 11, or may be independent structures connected to each other. The first protrusions 111 may be divided into multiple groups, a group of first protrusions 111 may be distributed at intervals along the axial direction, and each group of first protrusions 111 may be distributed at intervals along the circumferential direction. The positioning column 011 may contact the first protrusions 111 but not the inner wall of the center buffer ring 11, which is conducive to reducing the contact surface and reducing the restriction on the movement of the center buffer ring 11 due to buffering.

[0065] like Figure 5 As shown, in some embodiments of the present disclosure, the inner surface of the limiting groove 121 is provided with a plurality of second protrusions 122. The second protrusions 122 may be structures such as a hemisphere, a spherical segment, a cone, a prism, etc., as long as they protrude from the inner wall of the center buffer ring 11. The second protrusions 122 may be an integral structure with the edge buffer ring 12, or may be independent structures connected to each other.

[0066] The inner surface of the limiting groove 121 may include two side walls distributed along the axial direction and a bottom surface connecting the two side walls. At least one of the two side walls and the bottom surface is provided with a second protrusion 122. In some embodiments, both the two side walls and the bottom surface are provided with a second protrusion 122, and the second protrusion 122 of the bottom surface is distributed along the circumferential direction. The second protrusion 122 of the side wall may also be distributed along the circumferential direction. The lug 022 may be clamped between the second protrusions 122 of the two side walls and may contact the second protrusion 122 of the bottom surface.

[0067] like Figure 5 As shown, further, the thickness of the second protrusions 122 on the two side walls of the limiting groove 121 can be greater than the thickness of the second protrusions 122 on the bottom surface, thereby improving the bearing capacity and preventing the lugs 022 from contacting the side walls due to compression deformation.

[0068] In some embodiments of the present disclosure, the inner wall of the center buffer ring 11 may be provided with a plurality of first openings, and the contact area between the center buffer ring 11 and the positioning column 011 may be reduced through the first openings.

[0069] In some embodiments of the present disclosure, the inner surface of the limiting groove 121 may be provided with a plurality of second openings, and the contact area between the edge buffer ring 12 and the lug 022 may be reduced through the second openings.

[0070] The first opening and the second opening may be blind holes or through holes, and their shapes are not particularly limited.

[0071] In other embodiments of the present disclosure, the inner wall of the center buffer ring 11 is a circumferentially distributed wave structure, and the wave structure has peaks and valleys distributed along the circumferential direction. The peaks can contact the positioning column 011, while the valleys do not contact the positioning column 011. This can also reduce the contact area between the center buffer ring 11 and the positioning column 011.

[0072] One or more of the above-mentioned first protrusion 111, second protrusion 122, first opening, second opening and wave structure can be used simultaneously in some embodiments. For example, the inner wall of the center buffer ring 11 can be provided with the first protrusion 111 and the first opening at the same time to improve the buffering performance while ensuring the structural strength.

[0073] At least one of the buffer ring 1 and the support structure 2 is made of elastic material, which may include silicone, rubber, etc. The elasticity of the material itself is used to improve the elasticity of the buffer connector 03 and improve the buffering performance. When the elasticity of the elastic material weakens due to the increase in usage time, the flexibility of the buffer ring 1 and the support structure 2 itself can still continue to provide a buffering effect, thereby extending the usage time and avoiding frequent replacement. Of course, metal, plastic or other materials can also be used. Due to the connection of the support structure 2, it can also have a certain flexibility to achieve buffering.

[0074] In some embodiments of the present disclosure, the buffer ring 1, the first protrusion 111, the second protrusion 122 and the support structure 2 are an integrated structure and may be made of silicone material, so that they can be integrally formed through an injection molding process, which is beneficial to simplifying the process, reducing costs, and reducing the installation process.

[0075] The terminal device disclosed in the present invention may be a projector or other equipment such as a television. As long as it has a vibration device that can generate vibration and its vibration needs to be buffered, the buffer connector 03 disclosed in the present invention may be used, and no special limitation is made to its application scenario.

This application is intended to cover any modification, use or adaptation of the present disclosure, which follows the general principles of the present disclosure and includes common knowledge or customary techniques in the art that are not disclosed in the present disclosure.
