The importance of speakers to speakers
The importance of speakers to speakers
As the saying goes, "The sound is good, and the loudspeaker the final say!", Do you really know how important speakers are to stereos?
This should be considered from the perspective of structure and function. The sound system is composed of three parts: speaker unit, box and frequency divider. The function of the sound system we buy is to amplify the sound, and all the sounds need to be emitted through the speaker. The speaker is the key to amplify the sound function, and also the core part of the sound system. It can even be exaggerated to say that the quality of a sound system is the quality of its speaker.
So what quality should the loudspeaker reach? What are the requirements for a good stereo?
1. Technical indicators meet the standard
When buying a stereo, we always pay attention to the hard parameters first, because although the sound is subjective, the parameters are objective; Although it cannot be based on parameter theory, parameters can always help us narrow the scope of selection and improve the quality of selection to a large extent with a bottom line thinking. Many parameters of audio, such as power, frequency response, distortion, signal-to-noise ratio, separation, and chip performance, are very important. The parameters of the speaker unit itself, "power, frequency response", are the most basic requirements of the speaker, and are also the hard indicators that the speaker must meet.
Take power as an example. The power also has rated power, which does not distort the power and peak power after a long time of operation. The maximum power of the speaker is generally 2-4 times of the rated power of the incoming speaker. For most people, the sound set in the room is loud at 20W rated power, and 60W in the living room is enough. The sound will be louder and louder at higher rated power.
Other parameters, such as frequency response range in line with functional positioning, distortion not higher than 1%, signal to noise ratio above 80db, and well-known digital power amplifier chips in the industry, are not necessarily perfect, but at least meet the standard. On the basis of reaching the standard, consumers can continue to measure whether they need higher parameters and whether they are worth spending higher prices.
2. Materials and details are in place
The material of speakers will affect the quality and functional focus. As a very fine product, the design of any link will affect the listening experience. The more high-end the sound, the better the details and quality will be controlled. Attention should be paid to the sound system. Attention should be paid to the materials and details of the speakers.
The diaphragm materials of the tweeter unit are mainly hard dome, silk dome and composite membrane dome. The hard dome is transparent, beautiful, clean, fast in sound transmission, and has high resolution. The high frequency response of the silk dome is clearer, more delicate, and more extensible. The sound perception is soft, and the high frequency of the composite membrane dome is natural and smooth. Although it is slightly inferior to the first two, it combines some advantages of the hard dome and the silk dome with low cost, At present, most speakers will choose him.
The materials of horn sound basin mainly include paper basin, ceramic basin, bulletproof cloth, wool basin, polypropylene, etc. Different materials have corresponding characteristics. The ceramic basin is good at expressing voice and classical music, and the bulletproof cloth basin has a wide frequency response and low distortion, but the cost is high. The voice of the wool pot is mellow and natural, and it is good at expressing soft music, but poor at bass and rock music. Polypropylene basin performs well in all aspects, but the price is high. In fact, the most common is the paper basin. The price is appropriate, the voice is clear, bright, smooth and natural, and it has a good performance in all aspects, but the moisture resistance and consistency will be poor.
As for the details and quality, there are a lot of things involved, including the design of interior wiring, shape details, sound absorption, shock absorption, etc., which needs more professional insight and consideration. If you are interested, you can tell us again~
3. Multiple speakers are carefully configured
In terms of speaker quality, it is very important to have multiple speakers carefully configured, which is based on two needs: first, to achieve high power, and second, to ensure sound performance in all frequency bands.
How important is power to a sound system? I believe it goes without saying. Although the sound size of a sound system is related to many factors, fundamentally speaking, power is decisive! It ultimately determines the maximum sound intensity that the speaker can emit, that is, the upper limit of sound loudness. In order to achieve high power, there are usually multiple speaker combinations. The more speakers, the greater the power, and the farther the sound can be heard. But the more, the better. It is enough to match the power of the power amplifier and meet your own sound needs.
Then why do you need multiple speakers to perform well in each frequency band?
Because what we need is a sound that can give good consideration to distortion, transient and power in the 20Hz-20KHz frequency response range, and can achieve clear treble, full midrange, and low bass, and can perform well in all frequency bands to meet these basic needs.
However, with only one loudspeaker, it is difficult to meet such performance requirements. The full frequency loudspeaker seems to be good, which solves the problem of poor frequency division design. The overall performance is balanced, especially in the medium frequency aspect, which is very expressive. It is suitable for listening to human voices, and the distortion rate in the ear is low. The human voice is quite full and natural, and the cost is not high, but it is slightly poor for high-frequency and low-frequency meters, which cannot achieve the audio-visual effect we need. Therefore, the simplest idea in the speaker design is to let the speaker units perform their own duties. The speakers in multiple frequency bands are carefully configured, and the use of split band playback. For those with higher requirements for sound, tweeters, mid-range speakers, and subwoofers can also be added to make the sound performance of each frequency band more perfect. However, the more the better, it is not enough to meet their own needs.
