I'm just an ordinary young man. I'm so picky about my headphones , I can say something, and I basically don't change the rhythm of listening to music. I also want to be self-willed, but I have no money, headphones, can speak out. Headphones, as long as they can make a sound, can basically, all the places can solve the headphone problem. But headphones really only need to speak out on the line. Xiao Bian wants to tell everyone that it can't really be heard. Let's look at Xiao Bian to see if it sounds just the earliest standard for headphones.
Before beginning to say that entry-level users need to pay attention to the problem of selecting headsets, it is necessary for us to first popularize the principle of the sound of the headphones for our friends. Now if the headphones are subdivided, they can be divided into moving coils, electrostatics, and moving irons. Magnetic, pneumatic, and so on are very diverse. At present, the earliest headphones that our entry-level users have access to should be dynamic-type headphones. The principle of sounding dynamic headphones is similar to that of ordinary speakers. The effect is that through the connection of the coil and the diaphragm, the coil is driven by the current to drive the diaphragm to sound. Well, we don't say anything that is too complicated, so that the white friends will turn off the webpage directly when they see the trouble!
Is not a sound on the line of white users choose headset collection
So, in order to make up for the space, we should have something to do with the white friends? Thinking about this problem for a long time, it's really difficult to make up the words. Here we'll go through the general contents of the article. If you are interested, you can continue to watch. If you are not interested, you might be interested in seeing it! We will not mention specific earphone models for this time. If you want to know which one is appropriate, you can check out our guide books on the earphone channel. We just tell friends where to buy the headphones. It is more appropriate when buying. Need to pay attention to some of what, of course, what greedy little to eat a big loss what's in the headset market is also very common, do not read the article may be the next fool of you is oh!
Having said so much, the space is also about the same, let us go into today's white-level users to buy headset must-read collections! If you are not white, then there may be something that you can use. Oh, avoiding being fooled and knowing more about the headset is not bad, and if you don't have a high fever, you will be fooled by a bad guy. It's fun!
Detailed explanation of each parameter Xiaobai knows nothing
When editing I was still white (although it is still now), I feel that when you chat with each other, you always give people a feeling of absolute professionalism. They always influence what frequency response range, ah, high-impedance headphones What is the sound of pushing up, how does the signal-to-noise ratio affect the sound, ah, the vocal tract separation indicator is in use in the end, and so on, and so on, it sounds very high and people listen to their chats. The time will feel that this group of people can, ah, what we say, we Xiaobai completely do not understand!
White friends first played a cold fan
In order to allow white friends to plug in their chat, or to enhance their own forcing, although these parameters are not particularly important for small white users to buy headphones, but the opening of this article we Still decided to introduce with friends, please note that this is definitely not to make room!
The frequency response range refers to the phenomenon that when a constant-voltage output audio signal is connected to the system, the sound pressure generated by the speaker increases or decreases with frequency, and the phase changes with frequency. This kind of sound pressure and The associated changing relationship of phase and frequency is called the frequency response.
Well-known headphone frequency range curve and parameters explain
The normal listening range of the human ear is indeed 20-20000Hz. We cannot hear more than this part, but this does not mean that other organs can sense the frequency beyond this range. As the saying goes, it sounds very comfortable.
In the field of headphones, the higher the impedance, the harder it is to push, and the greater the resistance, as the saying goes! Many people have said, we buy headphones to buy a low-resistance, low-resistance push. This sentence is not wrong in itself, but many people combine the impedance with the size of the voice. This connection is wrong.
The parameter that often appears at the same time with the impedance is the sensitivity, the sensitivity is generally expressed by XXdB/mw, and the sensitivity represents the volume of sound emitted by each milliwatt. This is the parameter that represents good or bad voice. The role of impedance in the headset can be explained by "potential". In general, high-impedance headphones have a high potential, so that we need high-power output to release it at all the energy, that is, to achieve a small distortion within the frequency response range.
The subtle relationship between impedance and sensitivity in headphones
What is the remaining signal-to-noise ratio, ah, channel separation, ah, these things say more, no one wants to read, after all, this is mainly for the small white user service, so these are relatively high-end News, who would like to see ah. Below we still come to dry goods!
I want to buy online magic is å¿½æ‚ is not much?
Xiaobai User: I'm going to buy a magic sound headphones into a cold wave of people, but why the price is so high, a headset to sell to 1,000 yuan, this is to grab money, go on TB to see, the original store What is a liar, TB bought on one or two hundred!
What's so cheap about the magic sound?
Xiaobai User: Recently, I have to travel. I wear a noise-canceling headset on the plane. I searched the Internet. This brand of noise-reducing headphones, called BOSE, was able to buy more than 800 headphones. It doesn't matter. The rest of the sale of one or two thousand is no different from this estimate, the order was bought, and so received the enjoyment of the next moment of quiet it!
This is the inner monologue of some white friends. In fact, with the changes in people's shopping habits, online shopping has become the most common way for people to shop, especially when buying headphones, not all cities have Headset store, but you do not know much about the price of headphones, online headphones and so cheap to sell, really worth buying it?
In fact, manufacturers of earphones have strict control over the price of earphones. For some malicious price cuts, they are in violation of regulations. After knowing this, go to the official website of the headset and the physical store to see, compare the price, as long as the price is not second-hand, the gap can not be too large. Shops with over-reputation may also be brushed by themselves. When buying, friends must pay attention to what you don't believe in fake or lost ten. Maybe your money can really buy twenty or fifty fakes. Goods, electricity providers buy headphones or find regular it!
It's like Dalan Xiang
Since friends know that some unscrupulous small stores can't be purchased with headphones, then there are no problems with the quality of the headsets that have good quality or have foreign relations and sell parallel and factory goods. Editor I have been heard more than once, you say how the price of headphones factory goods, how do you say I buy a parallel headphones with the State Bank can have much difference, editing I really do not know what, if not you say What kind of factory goods ah parallel goods, what, I have not heard of these!
Factory goods are absolutely false
In order to be able to answer this question from the friends around me, I specially edited the Internet to check out what is factory goods and parallel imports. Afterwards, if I want to say something, these things are like a residue! The factory goods can be understood as the semi-finished products and discarded earphone products inside the headset factory, and then brought back through the recycling or the employees in the factory. This thing is half garbage. After you spike home, it will be broken in two days. You have no place to repair, you can buy garbage at cheap prices. What are you willing to do?
The price of the Bank of America is only mainstream, and it also carries a "bargaining" price range.
The parallel headphones we know most are some of the earphone products of the American Bank, the Bank of China and the Bank of Japan, all of which are headphones obtained from foreign countries through informal channels. Although it is now catching up with the United States, it is a good time to buy, when the usual words are still considered, this headset is also no warranty and after-sales service, if it is broken, it can only be a body or spend money to repair, save a few Money is all a repair fee!
BNM is the most reliable way to buy headphones
Therefore, the status of licensed goods is just like the excavator of Lanxiang, and it is still not to be shaken. Besides, Xiaobai friends purchase entry-level headset products. The price difference is not too bad. Don't buy a gadget to make people fool .
Written at the end:
After we wrote Xiaobai Baodian, we wrote it first, and even more feared that our friends would be angry with the website, and there was no impulse to read it. In fact, if we buy earphone products, as long as we don't want to be cheap, then Nothing can be fooled! This time, it's okay, but there is one more thing I want to say. I'm planning to keep talking with my friends for the next time. So, let's talk about it today. The rest will be with friends next time!
