The sound of steel mats is high in density, fast in speed and clear in sound. However, it has the disadvantages of being thin and cold. If your equipment is not very clear and you want to improve the sound, steel is a good choice. The sound of natural stone has steel. Similar to the clear characteristics, the effect is slightly inferior to steel, but the unique magnetism of the stone is not difficult to hear. The South African black is the best in the stone. Because it is a natural material, some stones will have some resonance pickups, which can be posted on the back. The tape is removed, and the method of attaching depends on the material. The sound of natural raw wood is warm, full of pine scent, soft sound, but the sound is not as good as steel or stone. We should choose harder wood for wood. Of course, the wood is the first to push the purple altar. The sound of red sandalwood is still clear. With its unique and noble tone, it sounds good, and it has a good personality. There is no instrument sound that can be compared with it. However, it is not easy to find the price of the rosewood, and the price is not cheap. Other logs such as ebony and rosewood. Hualien is also good, it is one of the accessories worth investing in. As for Liuan or splint, the sound is not very good, we do not recommend it. There are so many woods on the market, we can't measure them all, and we hope that you can provide us with better wood, so that good sounds can be shared with everyone. Some of the other mats, such as glass and acrylic, have their own characteristics and effects, and are worth trying. Here is a small remedy, you can put a piece of glass under the TV at home, preferably a little thickness, at least 5, the quality of the image and sound will be improved.
Some people are afraid of vibration. They often put CDs and amplifiers directly on the ground, and even use carpets as mats. They hope to have the effect of vibration absorption. In theory, it seems that the floor is hard and the vibration is minimal. It seems to work, but in our experiments, the sound But the worst one is that on the one hand, the floor is the sound surface of the largest area, the vibration energy is quite large, on the other hand, the low frequency of the sound is below, we know that the low frequency energy is the biggest, this kind of release is contrary to health. the rules.
If it has to be placed due to space and use factors, it is best to use a mat to hold it up. Use three mats to separate the mat from the floor, and use the items that are readily available. Yes, such as oak pieces, wooden blocks, iron pieces (blocks), stones, etc. Of course, the cone is the best, but it takes a little silver. In addition, many people will go to the furniture store to buy the finished sound cabinets on the market. Most of the manufacturers who make furniture do not delve into the sound. Only considering the convenience and beauty, the sound position is not perfect, and many audio cabinets will The equipment is sealed in the cabinet, and the cabinet is made of thin splint. The negative impact on the sound is too great. If your home audio cabinet has a door (many are made of glass), you may wish to open the door to listen. You will find that there is a difference; the best way is to buy an audio rack specially designed for the sound, or you can order it yourself.
The sound rack is first and foremost, the natural material should be more steel, and some of the sound racks are thick, but the thin splints are placed on the rack. The better one is to use the nails to hold the board up. This is not good, the best is to use a thicker mat, hollow it in the middle, leaving only enough to place the equipment in place, if it is possible to empty the part of the screen will be better. This kind of practice is probably not done in the market today, but it doesn't matter, let's change it.
As for the material of the audio rack, steel is better than iron. If wood is used, it is best to use solid logs. Stainless steel has less topcoat. It will be better. If the tube is used, the tube is better than the square tube. Of course, it is better. However, the cost of solid wood will be much higher; now there is a kind of material in the industry called milling. It is said that the background noise of this material is very small. Some people used it to make a speaker stand. The effect is good. If it is used to make the effect of the audio frame, it should be expected. of. The best rack sound is a shelf of equipment. The height of the shelf is about 40~90. The sound will be lighter and the sound will be boring. This is the best position we have tried, and if you sit and listen, this It is also the height of the best operation, as to whether it is just in the middle part of the position, the sound is best to listen to, and some people have to do further research.
Many people often put the equipment on the long low cabinet of the TV station. The result of continuous mutual vibration is of course not good. If it is not allowed, it can be supported by the above-mentioned method, and the front stage is often placed. On the back level (maybe the front level is lighter), if possible, try to put the front stage separately and the sound will be better.
It is best not to put anything on the top of the audio equipment, including the speaker, and it is best to keep it clean, otherwise something will be released, the sound of something will run out, and after pressing the object, the high frequency will be compressed. The sound will be stuffy. From a technical point of view, the upper plate of the equipment is pressed, and it is somewhat shockproof. However, this requires technical means to solve it. There are many products after research that are commercially available. Some effects, we are the most effective way to keep clean at home, do you believe it? Even the dust on the equipment will affect the sound, if you focus on it, you will hear it. Usually we put the sound in order to be beautiful and neatly arranged in a row, parallel to the wall or the lower plate, in the theoretically parallel two planes will produce a standing wave related to the distance, which has some influence; Try it out and turn the equipment around.
If possible, let the bottom plate of the equipment not be parallel with the lower plate. Just a little angle, it is benign from the perspective of sound hygiene, but it can be compromised visually. I once saw someone using a rope to hang up the equipment. It seems that the vibration has the least impact, but don't forget, there is also a wave of sound energy that will hit the equipment, the equipment will sway, and of course the sound is fluttering, sometimes It seems that the upper sound field is very beautiful, the lower stage and the body are virtual, and we want the placement to be the static structure of the minimum contact area.
how to say? That is to say, the equipment uses the least support points and can be placed stably. The rope crane does not statically structure. From this point, we look at the feet of the equipment. The general equipment is to do four feet. We know that three points can determine a plane. If it is changed to three feet, the vibration of one foot will be lost, and the sound will definitely be good. This experiment has confirmed that there are some high-end audio systems in the market. From the contact surface of the feet, many of them are made of leather or similar synthetic rubber. The contact surface is still too big, preferably one point. This point cone provides a very good solution. We can use three in the foot cone, but it has a negative effect. If you don't want to spend money, look for three old people's tea cups at home, or enough to hold up the equipment to hold the equipment up, it is better to be harder, not too big, three just fine. To be honest, the rubber foot sound is not very good, and if you use a teacup, it is best to stuff something inside, such as cotton, toilet paper, otherwise the sound will sound embarrassing. When choosing the position where the equipment is placed, the best way is to stay away from the sounding area, that is, around the horn, but it doesn't have to be too far away. It is always bad if the wiring is too long; if it is not necessary, it must be placed in the horn. Behind, the impact is quite large. The four corners of the room are not a good place for the equipment, because the sound of the three sides of the corner space is here to turn, if possible, try to stay away from the large walls, especially the wooden walls that are not hard. The horn is one of the most important equipment for determining the sound. Some people buy a high-priced horn. They listen to the two corners. This is a bad thing. Generally, the design of the horn must be quite far from the wall. Produce a good sound (except for some speakers designed for corners), the distance and spacing of the speakers from the side and back wall determine the sound field, stage and positioning of the sound, and if the expensive equipment speakers are not well placed, the sound It is not good, it is possible to lose millions of audio to 100,000.
Next, let's talk about the placement of the line. Most people connect the equipment, and the line doesn't matter. The lines behind the equipment are often entangled in a pile. Also make it clear first, within the possible range, the line and the line should not be touched as far as possible (this is probably quite difficult), if you have to, try to separate the power line from the signal line, because AC power may produce hum, Also, hold the wire up and don't touch the face or the back wall, it will have a good effect. The speaker cable is most unsanitary to the ground, and it should be propped up. The effect of improvement after the support is quite remarkable. You can start from this line first, and the spring has the best effect. You may wish to give it a try.
The sound quality is accumulated bit by bit. The equipment can be changed. The adjustment also takes up a considerable amount. Often we are not good at high treble, the sound field is not good, and we have some equipment or wire to match. When I adjusted it a little, the problem was solved. I didn’t have the opportunity to change the machine. Some manufacturers changed the machine to make money, and then the sound became better. In fact, it was not a factor of equipment, and some audio commentators also When the speaker is released, it will start to listen. If you listen, you will write it. This method is also unfair. If you change the equipment, the frequency response will change. You should adjust the speaker first, and the sound will be flattened and listened. The judgment will be correct. Every action placed on the equipment may only provide a little help to the sound. However, the numerous additions will make the effect amazing. I wish you all a wonderful listening experience.
