What is the sound field that determines the sound, why does the big block not necessarily have a loud sound field?
The utility model discloses an Electronic Cigarette with atomizer oil core separation structure, which comprises a atomizer assembly and a battery assembly; The utility model has the advantages of reasonable structure design and high practicability. During operation, because the oil storage tank of the atomizer is completely sealed and the oil guide material is completely isolated from the oil guide material, the oil guide material will never contact with the oil guide material in the storage process Oil Coil Separation Pod Patent,Oil Coil Separetion Vape Pod Oem,Innovated Vape Products Oem,Oil Coil Separation Vape Products Oem Shenzhen MASON VAP Technology Co., Ltd. , https://www.e-cigarettefactory.com
The so-called sound field, in fact, the more accurate name should be the sound field. In Liu Hansheng's "Audio 20 Essentials", the space is still very large. The basic interpretation is to feel the sense of space brought by the sound in the place where your eyes can see. There are not only width and depth, but also height and thickness, so the sound field is shaped and positioned.
Well, you can understand that the biggest difference between audio and headphones is that the sound field is different!
Then the question comes, since it refers to the sense of space caused by the sound, then the louder the sound, the bigger the sound field?
In fact, the answer is wrong. I use another question to explain why it is wrong.
The larger the block size, or the larger the speaker size, the larger the sound field?
In other words, what is the sound field of the sound determined?
If the cabinet is bigger and the sound field is bigger, then the pair of boxes is absolutely unspeakable.
Obviously, the discerning person can see where the problem is. Those who have heard the sound will pay attention to the box of the speaker. It is placed in the corner or in the middle of the wall. It is placed on the top of the wooden cabinet or placed on the marble. How high, how far back to the wall, how long the amplifier line is, how big the room is, etc. If you put the sound in a book, I believe that with the case analysis, it can be compared to a "Xinhua Dictionary."
So in the next picture, you may not be able to feel a great sound field.
Let's review the words of Teacher Liu Hansheng. The sound field refers to the sense of space that you see in your eyes, but the sound is heard by your ears, so this is why the big horns dragged by the square dance can't give you the feeling of loud sound, because space Too big, its sound field has been scattered, no thickness, no depth...
Personally, this is how you feel. If you want to experience the sound field, you must have a premise, what kind of space you want to listen to. It’s in your living room, it’s okay to lie on the opposite sofa, pick up the TV and watch the movie, or in your 8 square meter study, only then, you can choose the right speaker, so you want to buy the right speaker, if you go Choosing, be sure to choose those auditoriums that are placed on the spot and are about the same size as your home.
If you agree with the above, then let's talk about the second element of the sound field. Does the sound block determine the size of the sound field?
This question is actually a pseudo-proposition, but in order to give you a clear direction, you can give another chestnut. The average person is 2.0 channels, so there are two boxes left and right; then someone will add a subwoofer to form 2.1 channels; but for the locals, he can set 5.1 channels or 7.1 channels, the more the channel is, the better To form a true surround sound, pay attention to the sound field is the sense of space, so there are symphony instruments placed, and there is the emperor's position, so you simply ask whether the sound of the block determines the size of the sound field is unscientific, and there are also manufacturers It's even harder to say that a small box of speakers is fitted with a large box.
Speaking of this, it is estimated that there are good people who will ask if there is a sound field in a single Bluetooth speaker.
The answer is yes. There is a sound field in theory. In fact, in order to improve the performance of the sound field, many Bluetooth speakers have also paid attention. For example, many brands, including BOSE, have cylindrical Bluetooth speakers. For example, the birdie speakers can connect two Bluetooth speakers together to connect the same device to form 2.10 channels.
However, on the sound field of the Bluetooth speaker, the speaker determines that the sound field size is correct.
Let's take a look at the Boomster of the famous German speaker manufacturer Teufel Defier. The size is bigger than the bluetooth speakers we have seen. You can say that it is a desktop speaker and it is not wrong, because it also supports USB and 3.5mm input. There are five speakers in the big head. If the number of speakers determines the sound field, it is definitely absolute. Let's see how the Germans play.
It is extremely rare to have five speakers in a Bluetooth speaker, because not as many speakers are better, and the design is very elegant. The Defir Boomster's speakers are two 20mm tweeters, two 65mm midrange units and a 105mm subwoofer.
The low frequency is diffuse and has no direction, so the horn is designed to be downward, but the size of 105mm may cause resonance, so after adding a large base to the whole body, a pedestal is designed for the woofer.
Then why should the tweeter be designed as two 20mm, and the intermediate frequency should be designed as two 65mm?
There is another new problem here that is linked to the sound field, that is, the degree of reduction.
To be precise, in addition to going to the scene, what you hear in other ways is distorted. Even if you use the microphone to record the space information on the spot and make a CD, your device will make the sound distorted, let alone the current audio file, decode the transcode and decode the transcode, if you have to force it, You go to the scene to force, that is the king.
Bluetooth speakers are no exception, both to ensure a certain sound field, to have a good ability to restore, the three frequencies must be balanced. But then again, not everyone's ears need a balanced tri-band. Some people just listen to personal voices or heavy bass, so when it comes to the end, you say that the aesthetics of acoustics is metaphysics, and many people agree with their hands.
Finally, I reiterate my personal point of view. Although the sound field of the sound is very particular, for the ear, it is not simply a good or a bad one. The aesthetic height of each person is different, if you want to experience A good sound field, in fact, a lot of methods, but I want to say that the rational and scientific use of your equipment is the best way.
