Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to an anti-vibrato structure. Background Art

[0002] A speaker refers to a device that can convert an audio signal into sound. A speaker is the terminal of the entire audio system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. Currently, a lighting component is installed on the speaker housing, which not only provides an immersive audio effect but also creates a good lighting atmosphere, enabling users to obtain a good visual and auditory experience.

[0003] Currently, a lighting component is installed near the speaker on the speaker housing. When the speaker vibrates, the lighting component near the speaker on the speaker housing is not fixed reliably enough. The vibration of the cabinet and the vibration of the speaker interact with each other, easily generating additional vibrato. Summary of the Utility Model

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an anti-vibrato structure, which solves the problem that when a lighting component is installed near the speaker on the speaker housing, the fixing is unreliable and vibrato is likely to occur.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an anti-vibrato structure, including a fixing frame and a positioning step. A limiting step is provided on one side of the fixing frame. The positioning step is provided with a first positioning portion and a second positioning portion. The first positioning portion is higher than the second positioning portion. The limiting step is fixedly connected to the first positioning portion, and the bottom of the fixing frame is higher than the second positioning portion.

[0006] Among them, a lighting component, such as a light strip, a lamp bead, etc., is installed on the fixing frame. The positioning step is designed near the speaker, and part of the mechanical vibration of the speaker is transmitted to the positioning step. By locking and fixedly connecting the limiting step on the fixing frame with the first positioning portion on the positioning step, the connection between the fixing frame and the positioning step is ensured to be reliable, and the fixing frame will not loosen easily and is fixed reliably. Therefore, when the speaker causes vibration, the fixing frame will not vibrate due to loosening to form vibrato.

[0007] Furthermore, the bottom of the fixing frame is suspended above the positioning step, and the bottom of the fixing frame does not come into direct contact with the positioning step. The direct contact between the fixing frame and the positioning step is the first positioning portion. When the positioning step vibrates, most of its mechanical vibration will not be transmitted to the fixing frame, and the interaction between the vibration of the fixing frame and the vibration of the positioning step is less, and it is not easy to generate vibrato.

[0008] As a further improvement of the present utility model: The fixing frame is provided with a first fixing portion and a second fixing portion. The first fixing portion is disposed at the bottom of the second fixing portion. The limiting step is disposed on one side of the first fixing portion. There is a gap between one side of the second fixing portion and the limiting step.

[0009] As a further improvement of the present utility model: A positioning member is provided between one side of the second fixing portion and the limiting step. The upper end of the positioning member extends to the upper end surface of the second fixing portion.

[0010] As a further improvement of the present utility model: The positioning member is made of silica gel material.

[0011] As a further improvement of the present utility model: A connecting portion is provided between the first positioning portion and the second positioning portion. There is a gap formed between the connecting portion and the first fixing portion.

[0012] As a further improvement of the present utility model: The upper end of the first positioning portion protrudes to surround and form a third positioning portion. A positioning opening is provided on one side of the third positioning portion close to the limiting step. The limiting step is embedded in the third positioning portion.

[0013] As a further improvement of the present utility model: A first mounting opening is provided on the limiting step, and a second mounting opening is provided on the first positioning portion. A fixing member is provided in the first mounting opening and the second mounting opening.

[0014] As a further improvement of the present utility model: A light guide plate is installed on the top of the fixing frame. A clamping portion is provided on one side of the light guide plate. The clamping portion is connected to the limiting step.

[0015] As a further improvement of the present utility model: The fixing frame is of an annular structure. There is a gap between the inner side of the fixing frame and the speaker housing.

[0016] As a further improvement of the present utility model: The positioning step is formed on the outer circumference of the speaker housing relative to the speaker.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] The present utility model fixedly connects the fixing frame with the first positioning portion through the limiting step, making the connection between the fixing frame and the positioning step reliable. Moreover, the bottom of the fixing frame is suspended on the second positioning portion of the positioning step, reducing the mechanical vibration transmitted from the positioning step to the fixing frame. There is less vibration interaction between the fixing frame and the positioning step, reducing the generation of flutter. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] In order to solve the technical problems in the prior art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0027] As Figures 1 to 3 shown, an anti-vibrato structure is disclosed in an embodiment of the present invention, which includes a fixed frame 1 and a positioning step 2. A limit step 11 is provided on one side of the fixed frame 1. The positioning step 2 is provided with a first positioning part 21 and a second positioning part 22. The first positioning part 21 is higher than the second positioning part 22. The limit step 11 is fixedly connected to the first positioning part 21. The bottom of the fixed frame 1 is higher than the second positioning part 22.

[0028] It should be noted that a light-emitting component, such as a light strip, lamp beads, etc., is installed on the fixing bracket 1, and the fixing bracket 1 can also be called a light guide bracket. The positioning step 2 is designed near the speaker housing. Part of the mechanical vibration of the speaker is transmitted to the positioning step 2, and the fixing bracket 1 is installed between the speaker housing and the positioning step 2.

[0029] The first positioning portion 21 is higher than the second positioning portion 22, that is, the first positioning portion 21 and the second positioning portion 22 are arranged in a stepped manner, and a positioning step 2 is formed at the position of the speaker housing 5 relative to the speaker housing. By locking and fixedly connecting the limiting step 11 on the fixing bracket 1 with the first positioning portion 21 on the positioning step 2, the connection between the fixing bracket 1 and the positioning step 2 is ensured to be reliable, and the fixing bracket 1 will not loosen easily and is fixedly reliable. When the speaker housing 5 vibrates or the speaker causes vibration, the fixing bracket 1 will not vibrate due to loosening to form a flutter sound.

[0030] In addition, the bottom of the fixing bracket 1 is higher than the second positioning portion 22, that is, the bottom of the fixing bracket 1 is suspended above the positioning step 2, and the bottom of the fixing bracket 1 does not directly contact the positioning step 2. The direct contact position between the fixing bracket 1 and the positioning step 2 is mainly the first positioning portion 21. When the positioning step 2 vibrates, most of its mechanical vibration will not be transmitted to the fixing bracket 1, and the interaction between the vibration of the fixing bracket 1 and the vibration of the positioning step 2 is small, and it is not easy to generate a flutter sound.

[0031] The fixing bracket 1 is designed as an annular structure, and the fixing bracket 1 is arranged around the outer periphery of the speaker housing. Correspondingly, a positioning step 2 is formed on the outer periphery of the speaker housing 5 relative to the speaker housing.

[0032] Furthermore, a plurality of limiting steps 11 are provided on one side or the outer side of the fixing bracket 1. Correspondingly, a plurality of positioning steps 2 are formed at the outer peripheral position of the speaker housing 5 relative to the speaker housing, and the number of the positioning steps 2 is the same as the number of the limiting steps 11.

[0033] Even further, the second positioning portion 22 is designed as an annular groove structure, and the first positioning portion 21 is higher than the second positioning portion 22. In order to save costs, the size, shape, etc. of the first positioning plate can be specifically adjusted according to the size, shape, etc. of the limiting step 11.

[0034] Preferably, a first installation opening is provided on the limiting step 11, a second installation opening is provided on the first positioning portion 21, and a fixing member 3 is provided in the first installation opening and the second installation opening. That is, the limiting step 11 is designed as a limiting column, and a first installation opening is formed by penetrating through the middle of the two ends of the limiting column. The limiting step 11 is arranged at the upper end of the first positioning portion 21, and the fixing member 3 sequentially passes through the first installation opening and the second installation opening to fixedly connect the limiting step 11 with the first positioning portion 21 of the positioning step 2, so that the fixing bracket 1 is fixedly connected with the positioning step 2.

[0035] More preferably, the fixing member 3 can be a screw. Correspondingly, the first mounting opening and the second mounting opening are screw holes.

[0036] As a preferred embodiment, the fixing bracket 1 is provided with a first fixing portion 101 and a second fixing portion 102. The first fixing portion 101 is disposed at the bottom of the second fixing portion 102. The limiting step 11 is disposed on one side of the first fixing portion 101, and there is a gap between one side of the second fixing portion 102 and the limiting step 11.

[0037] The fixing bracket 1 is designed as a two-layer structure. The width of the upper second fixing portion 102 is slightly smaller than that of the lower first fixing portion 101. By designing the limiting step 11 on one side of the first fixing portion 101, a light-emitting member can be installed at the upper end of the second fixing portion 102.

[0038] The first fixing portion 101, the limiting step 11 and the second fixing portion 102 are of an integrally formed structure.

[0039] When the fixing bracket 1 is designed as an annular structure, the first fixing portion 101 and the second fixing portion 102 are also annular structures. One side of the first fixing portion 101 is flush with one side of the second fixing portion 102. The other side of the first fixing portion 101 can extend beyond the other side of the second fixing portion 102, that is, the other side of the first fixing portion 101 close to the limiting step 11 extends beyond the other side of the second fixing portion 102 close to the limiting step 11. In this way, a gap can be formed between the second fixing portion 102 and the limiting step 11.

[0040] In addition, the other side of the first fixing portion 101 can also be flush with the other side of the second fixing portion 102, and only a gap needs to be formed between the second fixing portion 102 and the fiber step.

[0041] In some embodiments, a positioning member 4 is provided between one side of the second fixing portion 102 and the limiting step 11, and the upper end of the positioning member 4 extends to the upper end surface of the second fixing portion 102.

[0042] When a light-emitting member is installed at the upper end of the fixing bracket 1, a light guide plate is usually installed above the light-emitting member to obtain a better lighting effect. By designing the positioning member 4 between the second fixing portion 102 and the limiting step 11, the light guide plate is directly abutted against the positioning member 4, and the light guide plate is not pressed against the end face of the light-emitting member. At the same time, the vibration interaction between the light guide plate structure and the fixing bracket 1 is reduced by the positioning member 4, and the generation of flutter is reduced.

[0043] In some embodiments, the positioning member 4 is made of a silicone material. More preferably, the positioning member 4 is an L-shaped silicone member.

[0044] In some embodiments, a connecting portion 23 is provided between the first positioning portion 21 and the second positioning portion 22, and a gap is formed between the connecting portion 23 and the first fixing portion 101. The upper end of the connecting portion 23 is connected to the first positioning portion 21, and the lower end of the connecting portion 23 is connected to the second positioning portion 22. Or rather, the upper end of the connecting portion 23 extends to the first positioning portion 21, and the lower end of the connecting portion 23 is connected to the second positioning portion 22. The first positioning portion 21, the connecting portion 23, and the second positioning portion 22 constitute a stepped structure. The connecting portion 23 can be designed as a vertical straight section, and the first positioning portion 21 is higher than the second positioning portion 22.

[0045] By forming a gap between the connecting portion 23 and the first fixing portion 101 of the fixing bracket 1, the direct contact area between the fixing bracket 1 and the positioning step 2 is reduced, and the direct contact between the fixing bracket 1 and the speaker housing 5 is reduced. As a result, the interaction between the vibration of the fixing bracket 1 and the vibration of the speaker housing 5 is reduced, and it is not easy to generate flutter.

[0046] In some embodiments, a third positioning portion 24 is formed by the convex enclosure at the upper end of the first positioning portion 21. A positioning opening is provided on one side of the third positioning portion 24 close to the limiting step 11, and the limiting step 11 is embedded in the third positioning portion 24. More preferably, a gap is left between the limiting step 11 and the third positioning portion 24.

[0047] The bottom of the fixing bracket 1 is suspended relative to the second positioning portion 22. A gap is left between the first fixing portion 101 of the fixing bracket 1 and the connecting portion 23, and a gap is also left between the limiting step 11 of the fixing bracket 1 and the third positioning portion 24 surrounded by the upper end of the positioning step 2. Specifically, the direct contact area between the fixing bracket 1 and the positioning step 2 is reduced, and the direct contact area between the fixing bracket 1 and the speaker housing 5 is reduced. The interaction between the vibration of the speaker, the vibration of the speaker box, and the vibration of the fixing bracket 1 is reduced, and it is not easy to generate flutter.

[0048] In some embodiments, a light guide plate is installed on the top of the fixing bracket 1. A clamping portion is provided on one side of the light guide plate, and the clamping portion is connected to the limiting step 11. A positioning member 4 is provided between the light guide plate and the fixing bracket 1. The direct contact area between the light guide plate and the fixing bracket 1 is reduced, and the interaction between the vibration of the light guide plate and the vibration of the fixing bracket 1 is reduced, and it is not easy to generate flutter.

[0049] In some embodiments, a gap is left between the inner side of the fixing bracket 1 and the speaker housing 5. When the fixing bracket 1 is of an annular structure, a clamping member can be designed between the inner side of the fixing bracket 1 and the speaker housing / speaker housing 5, and the clamping member is embedded in the gap between the inner side of the fixing bracket 1 and the speaker housing 5. The clamping member and the limiting step 11 cooperate together to make the fixing of the fixing bracket 1 and the positioning step 2 more reliable, and it is not easy to generate flutter.

[0050] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present utility model are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0051] In summary, after reading the documents of the present utility model, various other corresponding transformation schemes made by those of ordinary skill in the art without creative mental labor according to the technical solutions and technical concepts of the present utility model all fall within the scope protected by the present utility model.
