Why is the sound quality of wooden speakers better than plastic speakers?
What kind of material a speaker chooses to make has a great influence on its sound quality. At present, the materials used for speakers on the market are mainly divided into two types: plastic and wood. The price of plastic is cheap, so the price of speakers made of this material is relatively low, and wooden materials are more expensive, especially the price of pure wooden speakers is much higher than that of plastic speakers. The advantages of wooden speakers can be explained from the following two points:
1. High density: Material density and quality are directly related to the cost of the speaker, and also affect the performance of the speaker. The greater the material density of the speaker shell, the smaller the vibration generated by the cabinet when the sound is emitted, especially for active speakers with high-power amplifiers, so that the sound can be more realistically restored. The density of wood is much greater than that of plastic, so the effect of wooden speakers is better than that of plastic speakers.
2. The playback effect is good: wood and plastic are much stronger in sound reflection, and the airtightness of wood is also very good, so that the sound signal can be effectively expressed through the air vibration in the box, and the thickness of the box To a certain extent, it is also a strong guarantee for the realization of the super bass effect. In addition to the above two points, wooden speakers are much more beautiful than plastic speakers in appearance and design, and will give people a noble and elegant feeling when used. If you are a music enthusiast, then a high-end pure wooden speaker is a must, only it can truly meet your needs. Of course, if your requirements for speakers are not very high, and you just use them as an indispensable peripheral of your computer, you can directly choose cheap plastic speakers. Finally, the resonance and airtightness of the cabinet are the advantages of wooden speakers over plastic speakers. The sound quality of wooden speakers and plastic speakers is very different because of different materials. The main reason is that plastic speakers are prone to resonance, while wooden speakers are wood. The cabinet is heavier than plastic, so it is not easy to cause tone distortion due to vibration. Secondly, wood can absorb harmonics better than plastic, just like a power grid. Like the high-order harmonics inside, there will not be too much noise, and the wooden audio is more atmospheric than the plastic audio.
Why is the speaker made of wood?
The saying that wood = good sound has been circulated in multimedia speakers for many years. Wooden speakers or wooden subwoofers account for more than 90% of all speakers. Obviously, the wooden cabinet has great advantages for current multimedia speakers: cost, appearance processing, sound control, and so on. But what exactly can wood bring? Can a wooden cabinet bring pure sound? First of all, let's take a look at why everyone says wood is good, and how the theory of "wood = good sound" is reasoned. We can easily find promotional materials for a speaker product. We found that in all products that use wooden subwoofers, regardless of the high, middle and low ends, they use the same sentence to describe "The subwoofer uses a wooden structure to eliminate resonance and box sound. , To minimize the sound dyeing, so as to obtain pure sound quality." do you understand? This is how the theory of "woody = good sound" is derived. Wood is good for controlling resonance. As a subwoofer box, it is easy to resonate the box material due to its low frequency. In this way, using a "wood" material of sufficient thickness as the box body will have a better effect than other materials such as plastic. However, as a mainstream 2.1 product, just because of the use of wooden structure, can the sound dyeing be minimized? In order to get good sound, it seems too simple to make speakers. In theory, as long as the box is strong enough to not resonate (vibrate), it makes no difference what material is used. The sound of the speaker is mainly determined by the three elements of the speaker unit, the cabinet structure design, and the frequency divider (the active speaker should include the power amplifier), and it has nothing to do with the cabinet material using "wood", or even plastic or metal. . Obviously, "wood" can only be regarded as an "optimal" choice for the subwoofer of multimedia speakers, instead of choosing "wood", it will definitely bring the "optimal" sound. Next, let's take a look at the "wood" that has always been quoted. You may have heard that Medium Density Fibreboard (MDF: Medium Density Fibreboard) is the most suitable for the manufacture of speaker cabinets. Even in the high-end products in the HiFi field, MDF is used to manufacture cabinets. Most multimedia speakers do not clearly state that their products use MDF but only talk about "wood" in the publicity. What's more interesting is that in a manufacturer's promotional materials it says: The subwoofer box uses MDF high-density fiberboard. Does it mean higher density MDF? may be. As for what kind of "logs" and "solid wood" they claim to use for their speakers, it is even more unreliable. What is MDF? It is a kind of board made by special bonding and pressing of powdered wood fiber under high temperature and high pressure. Compared with solid wood, it has a smoother surface, high strength, and is not easy to deform and crack, so it is widely used in various fields. It is very suitable for speakers. At present, many low-end multimedia speakers use "particle board". This kind of board is also made by special bonding, but the wood fiber used is relatively rough, and the inferior particleboard fiber is very rough, although it has the same smooth surface and good quality. The strength, but easy to be damp and cracked. As for solid wood, the surface treatment is more difficult, and it also has the shortcoming of easy cracking. It is used very little, and of course it will not be used in multimedia speakers. Back to the multimedia speaker products, although the same "wood", it does not mean that everyone's cabinets are the same. The proportion of products that can use MDF is not large, especially low-end products and some small-brand products. If you encounter inferior "particle board" cabinets, perhaps the life of this product will be greatly challenged due to different use environments. In multimedia speakers, if a brand's products blindly add the slogan of "wood, prevent resonance, and bring excellent sound", then we have to doubt how they treat each speaker when designing the product. Of the sound. It is easy for us to think that with the "wooden" cabinet, the sound is all right. And those manufacturers who use "particle board" and still keep saying that they use "wood" materials will bring pure sound quality. You should also think about it. Everyone has seen your wooden cabinet, but your "pure sound quality" has How many users can agree?
