The effect of the structure of earplugs on sound quality and ears

The structure of the earplugs looks very simple, only one sound unit, but in such a small sound unit to do in a number of sound units to be able to achieve the sense of the range, but also a very difficult thing! First of all to talk about the structure of the headset, the headset is not like cheap beats the box, not completely closed headphones cavity, and now the basic design of the earphone cavity are stomatal balance, and its intention is similar to the inverted phase of the audio and video, Through the reflection of the sound waves to achieve the role of enhanced bass, my hands on the existing few pairs of earplugs, Sen Department of design is no doubt from the physical structure is in line with the requirements of the box! Here is the Sen Department of ear plugs as a model to explain. Often we said the headset behind the so-called stomata, that is how deep is true, how deep is the false oval half of the hole, it is not a stomata, I personally tried, that move regardless of the real Fake, are all closed! The The In fact, combined with the above short space, this section of the prominent space is actually part of the box, not what stomata! The real stomata is actually a few holes behind the earbuds on both sides of the ears! If you break the earplugs, you know that the edge of the metal pelvis supporting the diaphragm is usually a small circle of moving eyes, it is the real stomata, it is like a large box of inverted space, usually in the above have a circle of high density sponge The washer, which is used to prevent dirt from entering the vocal cheap beats by dr dre unit directly from the stomata.

The following is said that the shock film, shock film of the transient stroke reaction to create air vibration, which sound, treble the smallest amplitude, but the highest frequency, bass the largest amplitude, but the lowest frequency. It should be from cheap beats by dre the physical structure, the ear plug diaphragm is a pair of contradictory body, the need to create high-frequency hard and easy to deformation of the material, and want to get a good low-frequency and rubber similar to the need for good deformation of the recovery of the material, Of the internal is not possible to put two vocal units into, which is subject to the current material process, the future is not possible, that is the words. It can be noted that the earbuds open after the diaphragm coil is divided into two parts of the center and around the voice coil around the diaphragm usually have some oblique stripes, from the physical point of view, this can improve the material For example, you put a piece of paper in the middle of the two bowls, you then put a chopstick up, will certainly fall, but if you turn the paper in the positive and negative direction several times, like Folding the same fan, and then along the vertical direction in the fold line up, you will find that a piece of paper can now bear the weight of even two chopsticks.

Back to the diaphragm said, why the edge of the diaphragm to make this shape, it is undoubtedly to improve the resistance of the whole membrane resistance, as a unit structure, the voice coil in the current through the vibration, the center Part of the type of change than the edge of the large part, that is, most of the bass is generated by the center, and then through the center of the pits on the hole after the introduction of the box, the clutter and then reflected from the stomatal headphones to the outside The So most of the treble is actually supported by the entire edge of the diaphragm produced! Because in the high frequency, the center of the diaphragm due to the design of the reasons for high frequency and no change, and the edge of the structure because of the strengthening of the area is limited, can produce a good high-frequency vibration effect at this point with the box Body speaker sound principle is exactly the opposite! The unit on the box in the bass, you can see the edge of the violent vibration, the middle part of the smallest, that is from the central part of the outward, the amplitude from small to large, and earplugs from the center of the center, The This is actually a very bold, but very perfect solution! As the ear-type earplugs, the unit area is tightly restricted, the big speakers on the unit, you can pay attention to, the voice coil will not be great, and in the ear plug, the voice coil area Outside the circle, so that the central part of the soft side, under the guidance of the voice coil can do a larger amplitude action, and the edge part, is suitable for some high frequency of movement.

A good earplug, relying on the precise physical acoustics design, which also includes good material science, so we are not so simple to imagine, including the choice of what the damping coefficient of the shock film material, how much area, voice coil The diameter of the wire, the diameter of the voice coil, how much the volume of the rear box, what shape, the location of the inverted position where the design, how much caliber, and only these problems can be very scientific and very good solution in order to make a good sound Of earplugs.

Currently on the market there are a lot of imitation Sen Department of earplugs, I also bought a pair of sound quality is not imagined so bad, and now want to come, the biggest benefit of piracy may be Sen Department of headset physical design, but in the voice coil, On, or fail to meet the requirements, and these two are the most critical! The So the results can naturally be imagined!

In fact, earplugs are also a variety of scientific and technological products, the domestic ear plug manufacturers beats by dre sale do not just light in the appearance of foot up and down enough effort, more in the design up and down writing effort, this is the development of the truth!

A good earplugs should be a very balanced product, in high school low frequency, if some users like, high frequency is very good, IF is also good, but unfortunately there is no low frequency, that in fact can be said to be as good as the flow of things.
