Description

Technical Field

[0001] This utility model relates to the field of HiFi audio technology, specifically a vibration damping base for HiFi equipment. Background Technology

[0002] Sound is produced by the vibration of objects. When an object vibrates, it causes fluctuations in the surrounding medium (such as air, liquid, or solid), forming sound waves. Once the vibration stops, the sound production also stops. Similarly, during the vibration process, it is easily disturbed by other vibrations, causing changes in the sound and timbre. In the field of Hi-Fi audio, numerous pieces of equipment drive speaker vibrations to reproduce the original sound of concerts and music performances through mechanical devices. This places extremely high demands on the vibration isolation of the equipment. Vibrations from cars on the road, the subwoofers in the performance hall, and the rebound of playback equipment on the rack are all factors to consider. Once external vibrations propagate to the equipment itself, the resulting cross-interference will inevitably affect the sound of the speakers, leading to distortion. In particular, if resonance occurs at a certain frequency, the music will be completely distorted. Therefore, a good rack isolates the equipment from each other and the speakers from the ground, achieving the most ideal playback conditions, that is, minimizing interference from external and internal vibrations. An even better rack should have its own fixed vibration frequency tuned to a frequency range imperceptible to the human ear, allowing the human ear to achieve true original sound reproduction within the perceptible sound range. Only in this way can Hi-Fi music achieve a true sense of presence.

[0003] There are many vibration-damping racks on the market today, including those using air flotation, magnetic levitation, and material weight. However, all of these solutions have their shortcomings. Therefore, there is an urgent need for a vibration-damping base for Hi-Fi equipment to solve the problem of rack vibration isolation. Utility Model Content

[0004] The purpose of this invention is to provide a vibration damping base for HiFi equipment.

[0005] A vibration damping base for HiFi equipment includes a base, a mounting seat slidably disposed on the top of the base via a support device, and multiple buffer and vibration damping devices provided on the base and the mounting seat. An adjustable height support cover is provided on the top of the mounting seat.

[0006] Furthermore, the support device includes a support slide column and a support slide groove. The support slide column is fixedly installed at the top center of the base, and the support slide groove is provided at the bottom center of the mounting base to slide with the support slide column. A vibration damping washer is sleeved on the outside of the support slide column to contact and cooperate with the support slide groove.

[0007] Furthermore, the buffer and vibration damping device includes corresponding upper and lower vibration damping grooves. The upper vibration damping groove is located at the bottom of the mounting base, and the lower vibration damping groove is located at the top of the base. An upper vibration damping tube is installed in the upper vibration damping groove, and an adjusting bolt is threadedly connected to the top of the upper vibration damping tube. A lower vibration damping cylinder is installed in the lower vibration damping groove, and the top of the lower vibration damping cylinder is fitted inside the upper vibration damping tube and slides with it. A vibration damping spring is installed between the upper vibration damping tube and the lower vibration damping cylinder.

[0008] Furthermore, the mounting base has external threads on its exterior and the support cover has internal threads on its interior. The support cover is adjustablely mounted on the top of the mounting base via these threads.

[0009] Furthermore, a rubber pad is fixedly provided at the bottom of the base.

[0010] In summary, this utility model has the following beneficial effects:

[0011] The supporting sliding column and supporting sliding groove of this utility model provide auxiliary support for multiple buffering and vibration damping devices. When the buffering and vibration damping devices perform buffering and support, the mounting base vibrates and shifts up and down under the sliding cooperation of the supporting sliding column and supporting sliding groove. The vibration damping washer can both fill the gap between the supporting sliding column and supporting sliding groove and play a role in buffering and vibration damping. When the HIFI speaker drives the rack shelf to vibrate, the rack shelf transmits the vibration to the mounting base. The mounting base drives the upper vibration damping tube to vibrate up and down along the lower vibration damping cylinder under the support of the vibration damping spring, which buffers, disperses, and reduces the vibration, minimizing the downward vibration of the HIFI speaker and the influence of the environment on the rack shelf. This results in a dynamic balance effect on the rack shelf, making it less prone to resonance and achieving the best sound reproduction effect. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described as follows:

[0020] A vibration damping base for HiFi equipment includes a base 1, a rubber pad 2 fixedly disposed at the bottom of the base 1, and a mounting seat 5 slidably disposed at the top of the base 1 via a support device. The base 1 and the mounting seat 5 are also provided with multiple buffer and vibration damping devices 7. The top of the mounting seat 5 is provided with an adjustable height support cover 8. The mounting seat 5 has external threads on its exterior and internal threads on its interior. The support cover 8 is adjustablely disposed at the top of the mounting seat 5 via the threads.

[0021] Every vibrating system (such as a mechanical, acoustic, or electrical system) has an inherent vibration frequency, determined by the system's own mass, elasticity, or structural characteristics. When the frequency of a periodic external force (driving force) approaches or equals the system's natural frequency, the system will vibrate with maximum amplitude, forming resonance. The system's own natural frequency is determined by its own weight, material elasticity, and structural characteristics.

[0022] From a structural perspective, there are three main characteristics. First, structural stability: vibration damping systems generally employ anti-loosening structures to ensure a solid, stable, and non-loose structure. Second, structural combination characteristics: by using different structural patterns, the vibration propagation path is broken down into irregular loops. Third, material elasticity: because the frame needs to bear heavy loads for extended periods, it is highly susceptible to deformation of elastic materials, but this is the most direct way to improve the frame's vibration damping effect.

[0023] In this embodiment, when used, as follows: Figure 5As shown, the rack shelf 9, which houses the HiFi audio equipment, is placed on top of multiple HiFi audio auxiliary balance adjustment vibration damping seats, i.e., multiple HiFi audio auxiliary balance adjustment vibration damping seats are used to support the rack shelf 9. The rubber pads 2 serve both as anti-slip and vibration damping. The height can be adjusted by rotating the threaded support cover 8 to keep the rack shelf 9 in a horizontal position.

[0024] When a HiFi speaker vibrates, the multiple HiFi speaker auxiliary balance adjustment vibration damping seats 7 placed under the rack shelf 9 provide cushioning and support, improving upon the traditional rigid connection or soft connection with rubber pads on the rack shelf 9. This gives it the damping effect of a soft connection while significantly increasing its service life. The principle is to buffer, disperse, and reduce vibration, minimizing the downward vibration of the HiFi speaker and the impact of the environment on the rack shelf 9. This achieves a dynamic balance on the rack shelf 9, making it less prone to resonance and achieving optimal sound reproduction.

[0025] The support device includes a support slide column 3 and a support slide groove 6. The support slide column 3 is fixedly installed at the top center of the base 1. The support slide groove 6, which slides and engages with the support slide column 3, is provided at the bottom center of the mounting base 5. A vibration damping washer 4, which contacts and engages with the support slide groove 6, is sleeved on the outside of the support slide column 3.

[0026] In this embodiment, the support slide column 3 and the support slide groove 6 provide auxiliary support for the multiple buffer and vibration damping devices 7. When the buffer and vibration damping devices 7 perform buffer and vibration damping, the mounting base 5 vibrates and shifts up and down under the sliding cooperation of the support slide column 3 and the support slide groove 6. The vibration damping washer 4 can both fill the gap between the support slide column 3 and the support slide groove 6 and play a role in buffering and damping vibration.

[0027] The damping device 7 includes a corresponding upper damping groove 71 and a lower damping groove 72. The upper damping groove 71 is located at the bottom of the mounting base 5, and the lower damping groove 72 is located at the top of the base 1. An upper damping tube 73 is installed in the upper damping groove 71, and an adjusting bolt 74 is threadedly connected to the top of the upper damping tube 73. A lower damping cylinder 76 is installed in the lower damping groove 72, and the top of the lower damping cylinder 76 is fitted inside the upper damping tube 73 and slides with it. A damping spring 75 is installed between the upper damping tube 73 and the lower damping cylinder 76.

[0028] In this embodiment, when the HIFI speaker causes the rack shelf 9 to vibrate, the rack shelf 9 transmits the vibration to the mounting base 5. The mounting base 5 then causes the upper damping tube 73 to vibrate up and down along the lower damping cylinder 76 under the support of the damping spring 75. This buffers, disperses, and reduces the vibration, minimizing the downward vibration of the HIFI speaker and the impact of the environment on the rack shelf 9. This results in a dynamic balance for the rack shelf 9, making it less prone to resonance and achieving optimal sound reproduction. Preferably, the damping strength of the damping spring 75 can be adjusted by the adjusting bolt 74, which is threaded into the upper damping tube 73.

Those skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model.
