Summary of fever and shock absorption knowledge
[Home Theater Network HDAV.com.cn] If you have configured a set of high-end equipment, it is difficult to hear the noble and pretentious tone of Hi-End, it is more difficult to achieve the fine and beautiful reduction, the stone is open. It’s the most shocking and high-spirited state, but the murmur of the sound field is rough and burr, and it’s the biggest “suspect†that destroys the sense of hearing. It’s probably a bad shock. You may wish to Start with the suspension measures of the equipment and carry out the "motor machine". You will definitely "have no doubt in the mountains and waters; there is another village in the dark and the flowers", Hi-End will radiate a dazzling brilliance, even if the guns will shine, the sound quality will be higher!
From the various aspects of the sound system, it is calm and heavy, especially the program source equipment and speaker system. Whether it is Blu-ray DVD in home theater or CD player in Hi-Fi, there are mechanical rotating components in the disc. The trajectory of the music signal is so tiny and slender, any slight vibration is harmful to the sound quality and is not beneficial. In the light, the distortion of the music signal is distorted, and the heavy one "jumps" and "crash". This is especially true for the speaker system: the speaker unit itself is a vibrating body. After the speaker is made, the whole body should be stable and thick, and the speaker should sing and dance. The music should be swayed in the box, and the box should be stationary.
Figure 1 shows Mark Levinson's top-of-the-line production, the No.30 decoder, which represents the highest technology of the Madrigal Sound Lab and the highest quality of Mark Levinson's products. Its unique and heavy shape makes it unforgettable. The split design completely separates the digital and analog parts, and reinforces the outer casing of the body. Even the shock absorbers have fine design considerations that do not induce interference between electrons and machinery. It sounds soft and pleasant, and the hall is rich in air. Full of sense, the sound is realistic.
Figure 2 is the flagship masterpiece of GOLDMUND - Apologue - a huge music elf composed of steel frame and wooden box. It is 1.8 meters high and weighs 325Kg. It is called "Big Mac" speaker system, it uses high carbon cast steel. The material has excellent shock absorption characteristics, and the scientific design of the structure can fully prevent the vibration of the speaker body, making the sound beautiful and completely free of sound.
Many high-end CD players use a suspension-type turntable structure to absorb shocks. Many cabinets are filled with cement, asphalt or marble, glass, etc. as a box material, largely for shock absorbers.
And I am not able to have good conditions for amateur enthusiasts to pursue the best means and effects of shock absorbers. Only some common methods can be used to improve the suspension measures of equipment.
Shock absorbers are commonly used for nails, shock plates and shock mounts. When the tip of the nail touches the ground, the vibration can be minimized, and the shock is generally matched with the speaker. The anti-vibration plate is made of marble, thick glass, metal parts or hardwood. The equipment can be pressed or spaced apart to avoid shock. The shock-proof frame is generally made of metal or hardwood. It is stable and strong enough to avoid various vibrations in the system. As shown in Fig. 3, the shock absorber of the finished product is equipped with nail feet under each layer, and the shock absorber effect is particularly good.
Another thing to note is that the nails of different materials have different listening sensations. Generally speaking, the iron and steel knots are strong, which is very suitable for home theater settings to enjoy the story disc. The wood and copper sounds are soft and suitable. Hi-Fi listening. The equipment with good shock absorbers sounds like the bass is not floating, the freely retractable, the layering, the resolution is very strong, and the sound field is very wide, you may wish to take the shock absorber as an opportunity to enter the fever paradise!
