Introduction and advantages of headphones
Headphones, as the name suggests, are worn on the head, not inserted into the ear canal, and are different from in-ear earphones. It is composed of two parts, a signal transmitter and a headset (usually a moving coil) with a signal receiving and amplifying device.
The transmitter is connected to the signal source, and you can also connect a preamp or headphone amplifier in front of the transmitter to improve the sound quality and adjust the tone.
advantage:
1: The sound field is good, the sound quality is very good, and the comfort is good.
2: Do not enter the ear, avoid scratching the ear canal.
3: Compared with in-ear earplugs, it protects the tympanic membrane.
Headphone classification
1. According to the working principle
Mainly there are two types of dynamic and electrostatic headphones. Although there are several types of equal magnetic types in addition to these two types, they have either been eliminated or have a very small market share for professional use.
Moving coil earphones: At present, most (about 99%) earphone earplugs belong to this category. The principle is similar to that of ordinary speakers. The coil in a permanent magnetic field is connected to the diaphragm, and the coil drives the diaphragm to sound under the signal current.
Electrostatic earphones: The diaphragm is in a changing electric field, the diaphragm is extremely thin, accurate to a few microns, and the coil drives the diaphragm to make a sound under the drive of the electric field force.
2: According to the degree of openness
Mainly open, semi-open, closed (closed)
Open earphones generally have a natural sense of hearing and are comfortable to wear. The HIFI earphones that are commonly used at home can leak sound, and vice versa, the outside sound can also be heard. The earphones have less pressure on the ears.
Semi-open: There are no strict regulations, and the sound can only enter but not exit, or only exit but not enter, and make corresponding adjustments according to needs.
Closed type: The earmuffs put a lot of pressure on the ears to prevent the sound from entering and leaving, and the sound is positioned correctly, which is more common in the field of professional monitoring.
3: According to the purpose
It is mainly used for Home, Portable, Monitor, Mix, and Binaural Recording.
