Description

Technical Field

[0001] The present invention relates to the technical field of audio and video shock absorption, and particularly to a shock pad and an audio and video device. Background Art

[0002] During the operation of an audio system, slight vibrations are inevitable. Devices such as ordinary CD players, Blu-ray players, Tape (recording decks), and digital players (hard disk digital players) have internal mechanical rotation drive systems that generate slight vibrations, and their internal transformers also generate certain slight electromagnetic vibrations during operation. The sound waves (i.e., beautiful music) emitted by the speakers will also cause vibrations in various devices of the audio system.

[0003] Components of audio equipment, such as electrolytic capacitors, inductors, and electron tubes, are very sensitive to vibrations. Although these vibrations are not easily detectable, they will be captured by sensitive components and fed into the audio signal, causing phenomena such as deterioration of the audio signal, such as distortion and energy loss, due to superposition resonance with the audio signal. This leads to a muddy sound in the audio system, a decrease in analytical power, loss of sound details, poor transparency, lack of low frequency, and an increase in distortion and noise.

[0004] This is unacceptable to audio enthusiasts, so various methods for improving sound quality have emerged. One of them is to place foot pads made of different materials under the equipment to reduce and change the system resonance condition, and the tone can also be adjusted.

[0005] There are a wide variety of foot pads, with materials including various metals, marble, hardwood, graphite, carbon fiber, etc., and structures including integral, sandwich, spring, spring plus ceramic beads, air cushion, water cushion, oil cushion, etc.

[0006] In practice, people have found that different materials of padding will have different sound performances, and none of them can meet the requirements of audiophiles for perfect sound quality, which is a consensus. The main reason is that most of the current similar products on the market use materials with poor shock absorption effects during manufacturing, and they even ignore the secondary interference of the vibration frequency of the padding material itself on the audio signal. It is precisely these vibration frequencies of the foot pads, although very small, even molecular-level vibrations, that once captured by sensitive components such as inductors, capacitors, and electron tubes on the equipment circuit and fed into the audio signal, will cause phenomena such as deterioration of the audio signal, such as distortion and energy loss, due to superposition resonance with the audio signal. What audiophiles often call "metallic sound" and "high-pitched sound" actually come from this.

[0007] In practice, there is also a phenomenon that a certain type of foot mat can only be used under one device of a certain system. Using it too much will produce unpleasant sounds. The more advanced the foot mat, the more prominent this phenomenon is. The most representative one is the "high-hill sound". The main reason is that this type of product uses the vibration frequency of the material itself to interfere with a certain frequency band of the audio signal, so that the distortion generated just satisfies the listening feeling of a certain frequency band and pleases the ears. Due to the distortion, the texture of the sound will not be good, so it cannot be used frequently in the system. There is also a phenomenon that when the volume is increased, the disadvantages of some foot mats will be exposed, affecting the sound texture.

[0008] At present, there are a few products on the market that use magnesium alloy as the damping material for audio equipment. Although a single magnesium alloy material can effectively eliminate vibrations and the treble, midrange, and bass are relatively balanced, its treble is too bright, not soft, has a metallic sound, and the bass lacks quantity and layers, resulting in difficulty in expressing the bass in modern broadcasting systems. Summary of the Invention

[0009] The main technical problem to be solved by the present invention is to provide a damping pad and an audio-visual device, which combine ceramics and lightweight alloys, have excellent damping performance and control ability, can reduce the vibration interference of audio equipment during music playback to the lowest level until it is eliminated, restore the original sound, have ultra-high resolution, a sense of line, and good density, making the treble floating and soft, the bass having more quantity, deeper bass dive, more solid elasticity, and richer bass layers, and better extension at both ends.

[0010] To solve the above technical problem, a technical solution adopted by the present invention is: to provide a damping pad, characterized by including:

[0011] A basic damping layer for absorbing vibrations and dissipating the vibrations by confining them within the basic damping layer.

[0012] A vibration blocking layer that is segmented and wrapped on the surface of the basic damping layer to block the transmission of vibrations.

[0013] In a preferred embodiment of the present invention, the damping pad includes a composite structure in the form of ABABA formed by the vibration blocking layer being segmented and wrapped on the basic damping layer.

[0015] In a preferred embodiment of the present invention, the A is the vibration blocking layer, and the vibration blocking layer is a ceramic layer, and the ceramic layer has a microporous structure.

[0016] In a preferred embodiment of the present invention, the ceramic layer includes a first ceramic layer, a second ceramic layer, and a third ceramic layer that are arranged in segments, and respectively cover and wrap the top surface, the middle surface, and the bottom surface of the magnesium alloy layer at intervals, forming two-stage vibration blocking.

[0017] In a preferred embodiment of the present invention, the interval height between the first ceramic layer and the second ceramic layer is 0.8 - 3.2 mm, and the interval height between the second ceramic layer and the third ceramic layer is 0.8 - 3.2 mm.

[0018] The interval width between the first ceramic layer and the second ceramic layer is 0.6 - 2.0 mm, and the interval width between the second ceramic layer and the third ceramic layer is 1.6 - 2.8 mm.

[0019] In a preferred embodiment of the present invention, the intervals between the first ceramic layer, the second ceramic layer, and the third ceramic layer are supplemented and covered with a gold powder layer.

[0020] In a preferred embodiment of the present invention, the connection interfaces between the first ceramic layer, the second ceramic layer, and the third ceramic layer and the magnesium alloy layer form vibration reflection surfaces, which are used to reflect and enclose the vibration within the magnesium alloy layer for dissipation.

[0031] Please refer to Figures 1 to 4 , the embodiments of the present invention include:

[0032] Embodiment 1

[0033] A shock-absorbing pad includes a basic shock-absorbing layer and a vibration-blocking layer. The basic shock-absorbing layer is used to absorb vibration and dissipate the vibration by confining it within the basic shock-absorbing layer. The vibration-blocking layer is segmented and wrapped on the surface of the basic shock-absorbing layer to block the transmission of vibration.

[0034] The shock-absorbing pad includes a composite structure in the form of ABABA formed by the vibration-blocking layer being segmented and wrapped on the basic shock-absorbing layer, where B is the basic shock-absorbing layer and A is the vibration-blocking layer.

[0035] The basic shock-absorbing layer is the magnesium alloy layer 100. Magnesium alloy has a damping effect of reducing vibration and noise, is an excellent metal damping material, has good dynamic characteristics and vibration reduction characteristics for impact pulse load, and the vibration disappears by converting elastic energy into heat energy.

[0036] The vibration-blocking layer is the ceramic layer 200. The ceramic layer 200 includes the first ceramic layer 210, the second ceramic layer 220, and the third ceramic layer 230 that are segmented and respectively cover and wrap the top surface, the middle surface, and the bottom surface of the basic shock-absorbing layer at intervals.

[0037] The spacing height between the first ceramic layer 210 and the second ceramic layer 220 is 0.8 - 3.2 mm, and the spacing height between the second ceramic layer 220 and the third ceramic layer 230 is 0.8 - 3.2 mm; the spacing width between the first ceramic layer 210 and the second ceramic layer 220 is 0.6 - 2.0 mm, and the spacing width between the second ceramic layer 220 and the third ceramic layer 230 is 1.6 - 2.8 mm.

[0038] The gaps between the first ceramic layer 210, the second ceramic layer 220, and the third ceramic layer 230 are supplemented and covered with a gold powder layer 300. On the one hand, it can improve the appearance beauty of the shock pad, and on the other hand, it can assist in reducing vibration.

[0039] The connection interfaces between the first ceramic layer 210, the second ceramic layer 220, the third ceramic layer 230 and the magnesium alloy layer 100 form a vibration reflection surface 400, which can effectively reflect and enclose the vibration within the magnesium alloy layer wrapped by the ceramic layer for dissipation.

[0040] The ceramic layer 200 has a microporous structure and can also absorb and diffuse the reflected vibration inside the shock pad to prevent resonance.

[0041] The first ceramic layer 210, the second ceramic layer 220, and the third ceramic layer 230 are segmented and covered on the surface of the magnesium alloy layer 100 to form an ABABA structure, which is divided into two levels to block vibration transmission, so that the vibration stress absorbed by the shock pad is dissipated by the internal magnesium alloy.

[0042] The shock pad includes a composite structure in which the ceramic layer 200 wraps and covers the magnesium alloy layer 100. The composite structure can be set into various shapes of shock-absorbing blocks, shock-absorbing plates, shock-absorbing frames or other suitable shock-absorbing structures according to actual usage requirements.

[0043] By utilizing the high-damping alloy characteristics of magnesium alloy, the internal response internal dissipation mechanism of its metal material is enabled to fully absorb mechanical vibration energy and convert the vibration energy into heat energy for dissipation, thereby achieving the effect of reducing vibration and noise of audio equipment.

The shock pad includes a composite structure in which the ceramic layer wraps and covers the magnesium alloy layer. The shock pad can be a shock-absorbing foot pad or a shock-absorbing foot nail pad, and is designed differently according to actual usage requirements.

[0046] The composite structure of a ceramic layer covering the magnesium alloy material has both the flexible side of a soft material, which can reduce vibration and improve musicality; and the rigid side of a hard material, which can improve audio control and resolution, thereby improving high-frequency sound quality and strengthening control over low frequencies; it can improve the volume, layering, elasticity and diving depth of the bass, making the system sound in a perfect pyramid shape, with a more solid upper and lower listening experience; at the same time, it has super high resolution, sense of lines, good density, the treble is elegant and soft, the low frequency has more volume, deeper dive, more solid elasticity, the bass layer is richer, and the extension at both ends is better.

[0047] The ceramic layer 200 is segmentedly covered on the surface of the magnesium alloy layer 100, forming an ABABA structure with excellent vibration reduction and control capabilities, which can minimize or even eliminate vibration interference from all directions when the audio equipment plays music, allowing the audio equipment to return to its original sound as much as possible.

[0048] The beneficial effects of the shock-absorbing pad and the audio-visual equipment of the present invention are:

[0049] By combining ceramics with lightweight alloys, and using two materials with different damping coefficients and external structures, the interference of vibration of audio equipment on audio signals when playing music is eliminated, achieving perfect reproduction of music.
