Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and more specifically, to a vibration-damping speaker. Furthermore, this utility model also relates to a television comprising the aforementioned vibration-damping speaker. Background Technology

[0002] Currently, the most common type of TV on the market uses a combination of speaker mounts and silicone pads to fix the back panel. The speaker mounts are clipped onto the silicone pad step structure, and the silicone pad is secured by the protruding holes on the back panel or the BOSS step on the back cover, thus fixing the speaker.

[0003] The silicone pads used inside existing televisions have weak elasticity and high hardness, resulting in poor energy absorption. When the speaker vibrates, the vibration energy is transmitted through the silicone pads to other components in the machine, causing resonance in loosely fitted components, which then rub against each other and produce sound. This leads to high rework costs due to customer complaints.

[0004] In conclusion, how to reduce the vibration of a speaker during sound output is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a vibration-damping speaker structure. The sound-generating component of the structure is provided with a vibration-damping buckle. The outer periphery of the vibration-damping buckle is provided with vibration-damping protrusions, and the two ends of the vibration-damping buckle abut against the back plate and the rear shell respectively. The vibration-damping buckle can support the sound-generating component, and the vibration-damping protrusions on its surface can play a vibration-damping role.

[0006] Another objective of this invention is to provide a television that includes the aforementioned vibration-damping speaker structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vibration damping horn structure, comprising:

[0009] A sound-generating component for emitting sound through vibration, the sound-generating component having perforations, the sound-generating component being disposed between the back plate and the rear shell;

[0010] A vibration damping buckle is provided through the perforation. The two ends of the vibration damping buckle abut against the back plate and the rear shell, respectively. The outer periphery of the vibration damping buckle is provided with vibration damping protrusions, which are used to reduce the vibration of the sound-generating component.

[0011] Preferably, at least six vibration damping protrusions are provided, the vibration damping buckle is a columnar structure, the vibration damping protrusions are evenly distributed along the axial direction of the vibration damping buckle, and the sound generating component is disposed between the two vibration damping protrusions located in the middle.

[0012] Preferably, the vibration damping buckle is provided with a groove extending along its axial direction.

[0013] Preferably, the vibration damping buckle is provided with a through head, which passes through a through hole in the back plate so that the back plate abuts against the vibration damping protrusion.

[0014] Preferably, the through head includes a limiting section and a guide section. The limiting section is a cylindrical structure, and the guide section is a frustum-shaped structure. The guide section is connected to the vibration damping buckle through the limiting section, and the size of the guide section gradually increases in the direction toward the limiting section.

[0015] Preferably, the guide segment has a chamfer at the edge opposite to the limiting segment.

[0016] Preferably, the vibration damping buckle, the vibration damping protrusion, the limiting section, and the guide section are an integrated component.

[0018] A television includes a vibration damping horn structure, a back panel, and a rear shell, wherein the vibration damping horn structure is any one of the vibration damping horn structures described above.

[0019] This utility model provides a vibration-damping speaker structure that emits sound through the vibration of a sound-generating component. The sound-generating component has a perforation, and a vibration-damping buckle is disposed in the perforation. The two ends of the vibration-damping buckle abut against the back plate and the rear shell, respectively. Vibration-damping protrusions are provided on the outer periphery of the vibration-damping buckle.

The vibration-damping protrusions on the surface of the vibration-damping buckle can increase the length and complexity of the vibration propagation path, making the vibration easier to absorb and dissipate during propagation, thereby playing a damping and vibration-damping role. This prevents the vibration from being transmitted to the back plate or the rear shell through the vibration-damping buckle, avoids resonance, and prevents collisions and friction between other components, achieving the effect of vibration reduction and noise reduction.

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The core of this invention is to provide a vibration-damping horn structure that can prevent resonance caused by the vibration of the sound-producing components.

[0027] Another core aspect of this invention is to provide a television that includes the aforementioned vibration-damping speaker structure.

[0028] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to 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 of this application.

[0029] This application provides a vibration-damping speaker structure, including: a sound-generating component 1 and a vibration-damping buckle 4;

[0030] Among them, the sound-generating component 1 is used to generate sound through vibration, and the sound-generating component 1 is provided with perforations. The sound-generating component 1 is located between the back plate 2 and the rear shell 3.

[0031] The vibration damping buckle 4 passes through the perforation. The two ends of the vibration damping buckle 4 abut against the back plate 2 and the rear shell 3 respectively. The outer periphery of the vibration damping buckle 4 is provided with vibration damping protrusions 5, which are used to reduce the vibration of the sound generating component 1.

[0032] Specifically, the sound-generating component 1 is connected to the control system inside the television. The control system sends commands to the sound-generating component 1, which then vibrates to produce sound. Please refer to the appendix. Figure 1The sound-generating component 1 is also provided with perforations, and the vibration damping buckle 4 is placed inside the perforations. The upper end of the vibration damping buckle 4 abuts against the rear shell 3, and the lower end of the vibration damping buckle 4 abuts against the back plate 2. Vibration damping protrusions 5 are provided on the outer periphery of the vibration damping buckle 4. When the sound-generating component 1 emits sound, it will vibrate. The vibration of the sound-generating component 1 will be transmitted to the vibration damping buckle 4, which it directly contacts. The setting of the vibration damping protrusion 5 can increase the length and complexity of the vibration propagation path, making it easier for the vibration to be absorbed and dissipated by the vibration damping buckle 4 during the propagation process, reducing the transmission and duration of vibration. By adopting this solution, the vibration of the sound-generating component 1 when it emits sound is reduced, so that the vibration cannot be transmitted to the back plate or rear shell through the vibration damping buckle, avoiding resonance and preventing collisions and friction between other components, thus achieving the effect of vibration reduction and noise reduction. This design can effectively reduce the resonance sound of the product and reduce the defect rate of the equipment.

[0033] Optionally, the vibration damping buckle 4 is a soft component, which can be a rubber component or a silicone component.

[0034] Based on the above embodiment, at least six vibration damping protrusions 5 are provided, the vibration damping buckle 4 is a columnar structure, the vibration damping protrusions 5 are evenly distributed along the axial direction of the vibration damping buckle 4, and the sound generating component 1 is located between the two vibration damping protrusions 5 in the middle.

[0035] Specifically, the structure of the vibration damping buckle 4 can be found in the attached document. Figure 2 The base structure is columnar, including but not limited to cuboids or cylinders. The specific structure should be selected according to the shape of the perforations on the sound-generating component 1. At least six damping protrusions 5 are provided on the damping buckle 4, evenly arranged in the axial direction of the damping buckle 4. Five annular grooves can be formed between the six damping protrusions 5. The sound-generating component 1 is fitted into the central groove. When the sound-generating component 1 vibrates, the vibration is first transmitted to the damping buckle 4. The annular grooves on the surface of the damping buckle 4 increase the path length and complexity of vibration propagation, making it easier for the vibration to be absorbed and dissipated during propagation, thus playing a damping and vibration-reducing role, reducing the transmission and duration of vibration. During the vibration of the sound-generating component 1, stress concentration may occur at the contact point between the damping buckle and the sound-generating component 1. The annular grooves can disperse stress concentration, making the stress more evenly distributed on the damping buckle, avoiding excessive local stress that could lead to intensified vibration or abnormal noise, thereby mitigating the vibration of the sound-generating component 1 to a certain extent.

[0036] In some embodiments, the damping buckle 4 is provided with a groove 6 extending along its axial direction.

[0037] For details, please refer to the appendix. Figure 2The damping buckle 4 is hollowed out from top to bottom, forming a groove 6. The groove 6 is a cylindrical groove. By setting the groove 6, the cross-sectional area of ​​the damping buckle 4 can be changed, thereby affecting its vibration stiffness. Vibration stiffness is the ability of an object to resist vibration deformation. After the stiffness changes, the vibration characteristics of the object also change. A properly designed cylindrical groove can reduce the vibration stiffness of the damping buckle 4, making it easier for it to deform when the sound-generating component 1 vibrates, absorbing and buffering the vibration energy of the sound-generating component 1, thereby reducing the transmission and duration of vibration.

[0038] Furthermore, the cylindrical groove 6 increases the friction area inside the damping buckle 4. When the sound-generating component 1 vibrates, the deformation of the damping buckle 4 causes relative movement between the groove walls. This movement generates friction, which in turn generates damping, converting vibration energy into heat energy. The increased damping can effectively suppress the amplitude of the vibration of the sound-generating component 1, allowing the vibration to decay more quickly, reducing the impact of vibration on the sound quality of the sound-generating component 1, and improving the stability and clarity of the audio output.

[0039] Based on the above embodiment, the vibration damping buckle 4 is provided with a through head 7, which passes through the through hole on the back plate 2 so that the back plate 2 abuts against the vibration damping protrusion 5.

[0040] For details, please refer to the appendix. Figure 2 The lower end of the vibration damping buckle 4 is equipped with a through head 7. Please refer to the attached document. Figure 1 The back plate 2 is provided with a through hole, through which the through head 7 at the lower end of the vibration damping buckle 4 can pass through the through hole, so that the upper surface of the back plate 2 abuts against the vibration damping protrusion 5 located at the lowest side of the vibration damping buckle 4. In this way, the vibration damping buckle 4 can not only play a role in vibration damping, but also play a role in supporting the back plate 2 and the rear shell 3.

[0041] Based on the above embodiment, the through head 7 includes a limiting section 8 and a guide section 9. The limiting section 8 is a cylindrical structure, and the guide section 9 is a frustum-shaped structure. The guide section 9 is connected to the vibration damping buckle 4 through the limiting section 8, and the size of the guide section 9 gradually increases in the direction toward the limiting section 8.

[0042] For details, please refer to the appendix. Figure 2 The through head 7 consists of two parts: a limiting section 8 and a guide section 9. The through head 7 has a frustum-shaped structure to ensure that it can pass through the through hole more smoothly and play a guiding role. The upper end of the through head 7 is larger than the lower end, which can lock the back plate 2 at the limiting section 8 to ensure structural stability.

[0043] Based on the above embodiment, the guide segment 9 has a chamfer at the edge away from the limiting segment 8.

[0044] Specifically, a chamfer is set at the lower end edge of the guide section 9 to reduce the difficulty of the guide section 9 passing through the through hole, so that the guide section 9 can play a better guiding role.

[0045] Based on the above embodiments, the vibration damping buckle 4, the vibration damping protrusion 5, the limiting section 8 and the guide section 9 are integrated components.

[0046] Specifically, the vibration damping buckle 4, vibration damping protrusion 5, limiting section 8 and guide section 9 are integrally molded and produced, eliminating the assembly step after the parts are manufactured, greatly shortening the production process and improving production efficiency.

[0047] Based on the above embodiments, the vibration damping buckle 4 is a silicone component.

[0048] Specifically, the reason for using silicone for the vibration damping clip 4 is due to the properties of silicone itself. Silicone has excellent elasticity, which can effectively buffer speaker vibration. When the speaker vibrates, the silicone clip can absorb and disperse the vibration energy, reduce the transmission of vibration, thereby reducing the vibration coupling between the speaker and the TV structure, and protecting the TV structure and other components from vibration.

[0049] In addition to the vibration-damping horn structure described above, this utility model also provides a television that includes the vibration-damping horn structure disclosed in the above embodiments. For the structure of other parts of the television, please refer to the prior art, which will not be repeated here.

[0050] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0051] The above provides a detailed description of the vibration-damping speaker structure and television provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
