How is the headset classified?
1, the most simple sub-law, can be divided into headset and ear plug type:
Headset is generally larger, have a certain weight, so easy to carry, but its expressive force is very strong, can make the world to enjoy the wonderful music.
Earbuds are mainly easy to travel out to listen to music because it's small in size. This type of headset is mainly used for CD audio, MP3 player, MD.
2, according to the principle of conversion (Transducer) points
Mainly dynamic (static) and electrostatic (Electrostatic) headphones two categories, although in addition to these two categories are equal to magnetic, electret and other species, but has been eliminated or for professional use market Possession of very little, do not discuss here.
Moving headphones (also known as electric): the vast majority (about 99%) of the headset earplugs are such, the principle is similar to ordinary speakers, in the permanent magnetic field coil connected with the diaphragm, the coil in the signal current Driven under the vibration diaphragm. Moving coil headset efficiency is relatively high, mostly for the audio on the headphone output driver.
Electrostatic headphones (also known as capacitive): The diaphragm is in a changing electric field, the diaphragm is extremely thin, accurate to a few microns (currently STAX new generation of static earphone diaphragm has been accurate to 1.35 microns), the coil in the electric field force Driven under the vibration diaphragm. Static headphones can reach the sound pressure level without moving coil headphones, but it's fast response, can reproduce a variety of small details, very low distortion. Because of its sophisticated structure, the material requirements are high, and more for manual assembly debugging, so expensive.
Static headset schematics:
There is also a dual-split headphones: dual-split headphones in the semi-open headphones based on the integration of both electric and capacitive advantages of their own dual-band headphones. It combines the advantages of electric, capacitive, closed, open four headphones in one, (this is a real "hybrid") such headphones in terms of dynamic range, transient response, playback quality, Sound thickness and so on are very outstanding, and its voice resolution is the best choice for music enthusiasts.
By the use of the situation, in general, the electric headset has a simple structure, stable sound quality, cheap and so on, suitable for the general selection, it can meet the general needs; capacitive headphones, good sound quality and bandwidth, but As the complexity of the process, the price is relatively high, suitable for enthusiasts use, its listening quality is quite good.
3, according to open degree points
Mainly open, semi-open, closed (closed)
A closed headset wraps your ear through its own soft pad to cover it completely. Such headphones because of a large sound pad, so the head is also larger, but with the sound pad can be used in a noisy environment without being affected. Earmuffs are more oppressive to the ears to prevent sound from entering and leaving, the sound is clearly positioned, and the professional surveillance field is more common in this field. However, there is a drawback that the headphones have a drawback that the bass is serious and the W100 is an obvious example.
The same time as the above-
Open headphones are more popular headset styles. This type of machine is characterized by the use of sponge-like microporous foam plastic production sound ear pads. It is small, wearing a very comfortable, no longer use heavy dye pad, so there is no isolation with the outside world, the sound can be leaked, and vice versa can also hear the voice of the outside world. If the headset is open to a high degree, you can hear the other side of the unit issued a sound, the formation of a certain feedback, making a sense of natural. But its low frequency loss is large, some people say it's low frequency accurate. Open headphones generally feel natural, comfortable to wear, common in the home to enjoy the HIFI headphones.
The same time as the above-
Semi-open headphones are a combination of closed and open two headphones advantages of the new headphones (it is a half-breed, the integration of the advantages of the first two headphones to improve the shortcomings), such headphones using a multi-diaphragm structure , In addition to an active active diaphragm, there are a number of passive driven diaphragm. It has a low frequency to describe the fullness of the rich, high-frequency description of bright and natural, clear levels and many other features, and now many of the higher grades of headphones is widely used in this headset.
4, according to the use of points
Mainly home (home), portable (Portable), monitor (Monitor), mix (Mix), head album (Binaural Recording)
