Afraid of audio provides vibration, the vibration shall affect the cries quality, this is the certainty we everyone know, an instil onto the audio gives vibration basis are driven motors, transformers, magnetic, acoustic and so speaker playback. In status towards finish vibration of the utterances of playback equipment, adjacent their own creations within the direction of thieve the shock, shock-absorbing measures, everyone horrify creations moreover cropped up, and a thick range, but inside general there are hard and gentle precursor tack pyramidal couple multiplies of shock-absorbing pad (Figure 1-10), can further abolish the influence of vibration onto the audio equipment. A range of distributed shapes, separate sections of dismay innovations by conduction, insulation and absorption of utterances gives itself, the host body (ground or table) and the cries of sure frequencies of vibration, thereby eliminating the leverage of vibration upward onto sound.
In nature, each object has its inherent resonant frequency, each of distinct density parts because of their own, they are not the identical as the natural resonant frequency of the vibration frequency of the conductivity is different. Therefore, the cushioning device, the physical properties of appointed members inside the direction of be essential. The substance now caused offend gear can be distributed into roughly five:
low damping membership with tall elasticity, for example aluminum, stainless iron and ceramics, this sharp garment form of the substance inside the locality of 40Hz vibration frequency changes with the transient proficiency of a princely revision within the big frequency transmission scope for is upper than the mild material;
damping coefficient of elastic material, such as timber, between vibration transmission pledge between iron and rubber;
low coefficient of elasticity of big damping constituents such as rubber, vibration within the locality of the transmission scope for of 200Hz with the frequency fluctuations;
low elastic modulus material, such as sponges, etc., with the frequency of vibration of the transmission capability raises and a steady decline, has small appearance on the frequency changes, but not without obstacle convey high-frequency vibration;
composite elements such as stainless iron and rubber, both on the vibration of the transmission capability of both worlds.
Feet nails, tripod, etc. are the consumption of exactly right media and geometric shapes, the audio provides body shell and the shouldering binding within the direction of minimize contact, writing a high acoustic impedance zones towards generate the impression of isolation or vibration of the cries scheme is "mechanical grounding." Foot fastener hard pyramidal junction inside the direction of the implement itself, the vibration export, but also inside the direction of mechanisms vibration barricade with the exterior world, within order that the interior and external audio equipment, the consequence of vibration on tone value can be reduced. An creative scare leg fastener ought be upheld out where the vibration of the vibration of the technical vitality into warmth dissipation away. Cone consideration of divergent substances own their feet tied a rooted resonant frequency, each with advantages and disadvantages, which ought be chatted past involving the.
Shock-absorbing cushion towards soak higher the vibration equipment, because distinct substances can be divided into foam mat, rubber mats, fake mats, nap mats, etc., within alignment inside the direction of collect a supportive shock-absorbing effect, must be picked towards suck the producing frequency phase of the rhythmic disruption shock-absorbing cushion, whereas the successive on the audible frequency ultra low frequency (10Hz or less) in the direction of be awash upward in the direction of boost the tones clarity. Shock-absorbing pad is principally apt for LP turntable, compact magnetic disk entertainer to use, the impression can be summarised as immediate, such as shock-absorbing pads placed below the disc storage processes player, the playback usefulness will be significantly improved, tighter bass, advanced audio and TV focus, the human voice plural clearly. Shock-absorbing pads made neat of divergent materials, conduction of the vibration frequency and conduction velocity were different, this is the pivotal to use. Such as in weighty masonry to the bottom, else put in their gentle shock-absorbing cushion, you can own better results.
Angle cone and shock-absorbing pad acclimatized in combination, can be integrated between the two long, rigid cone consideration so that the fruitful vibration transmission, after the vibration transmission to the shock-absorbing cushion, because of high damping laminated material molecules collide and the vibration of the mechanical intensity into heat energy, the energy of vibration incapable to collect in the cone in the vicinity, and the utilisation of distinct materials owned distinct resonant frequencies, damping for distinct frequencies owned dissimilar characteristics, so this amalgamate can be geared towards the top with a quite wide waist narrow piece absorption and damping, so the utmost results.
