As people's lives continue to improve, people's demands for quality of life also rise. In this environment, the audio industry is gradually moving towards the mainstream consumer market. As a part of the sound, the important part of the sound, the purchase of the sound has a very important meaning. How to choose high-quality audio is also a common-sense knowledge that consumers need to know.
[Preliminary observation]
For the initial understanding of the sound, you can use the "view, slap, knock, recognize" steps to identify: that is, a process, two weights, three knocking boxes, four recognized nameplates. Viewing the craft is to judge the quality of the sound from the first impression of the sound appearance: the sound made with natural logs is of course the best, but because of the high cost, often do not recommend mainstream.
The common sounds are decorated with a thin layer of veneer on the surface of MDF medium-density fiberboard: the sound of the real veneer, especially such as rosewood, bird's eye, rosewood, walnut, lotus, red oak, etc. Rare veneer, its natural wood grain has excellent visual effect and feels smooth and comfortable.
[掂 weight]
The good sound is mostly made of high-quality MDF particle board of 18~25mm, and the high-grade flagship sound is made of super heavy wood or multi-layer composite plywood such as red sandalwood and yellow pomelo, so the weight is very amazing. Counterfeit and shoddy products are made of poor quality paperboard, so the weight is generally lighter.
[knocking box]
The knuckles are used to strike the upper and lower left and right baffles of the box. The sides of the box are solid and slightly brittle. The material of the board is hard and thick, and there are many reinforcing ribs inside. The structure of the box is reasonable and strong. A variety of sound insulation and anti-standing wave measures. This type of box is costly and difficult to process, so there are few counterfeit and shoddy products. If you use the knuckles to tap the box to make a "å™—, å™—" sound, the board is too thin, the material quality is too poor, and the structure is unreasonable. There is no sound absorbing material or ribs inside, which results in a large amount of diffuse reflection and standing wave formation in the box. It is impossible to obtain a good playback effect by purchasing this type of sound.
[nameplate]
As mentioned above, behind the finished audio, there is usually a technical label: the content is nothing more than the frequency range, sensitivity, carrying power and impedance of the speaker. The sensitivity rate is the most important indicator of the speaker, which determines to a large extent what kind of power amplifier should be selected for the box, how much power to push and so on.
Another most important indicator is the frequency range. The better the low frequency response of the sound: 20KHz represents the high frequency extension that the sound can reach. The higher the number, the better the audio characteristics. Some audio does not indicate this indicator, and the frequency extension range will become very wide.
[listening stage]
After taking the eye part into consideration, the following is the audition of the ear part.
First, listen to the characteristics. In general, a good sound will have its own unique sound characteristics.
Second, listen to the details. Good sound, but good sound quality is not in the display of external atmospheric sounds, but in its handling of sound details.
Third, good sound tolerance must be high. Many stereos are listening, and the first listener will make the listener happy, the sound is clean and the texture is good, but this does not necessarily mean it is a good sound. In the next period of time, perhaps the listener will find that its voice gradually loses its original color and becomes dry and tasteless.
