Rich Types Of Headphones

Because of the different uses of earphones, the types of earphones are gradually enriched. The types of earphones can be broadly divided into open type, closed type and semi open type.

Open earphones generally sound natural and comfortable to wear. Here, comfort means no stuffy feeling. It is commonly used in hifi earphones for home appreciation. The sound can be leaked out, and conversely, the external sound can also be heard. The earphone has less pressure on the ear.

There are no strict regulations for semi open earphones. The sound can only enter or exit, and the design can be adjusted according to the needs of use.

The ear muff of the closed earphone adopts a completely closed structure, which can prevent the external sound from entering, and the pressure on the ear is large. The sound positioning is accurate. This structure is often used in professional monitoring fields. Some closed earphones also have the sound field of open earphones, which keeps high-quality sound while isolating noise,

With the development of earphones, the most important sound unit is still the dynamic sound unit. After so many years of development, the dynamic earphone technology has become very mature, but it has also encountered a bottleneck in sound improvement. In addition to static earphones, there are also many derivative technologies for dynamic voice units, of which the most widely used is the dynamic iron voice unit.

The moving iron pronunciation unit uses the electromagnet to generate an alternating magnetic field. The vibrating part is an iron piece suspended in front of the electromagnet. When the signal passes through the electromagnet, the magnetic field of the electromagnet will change, so that the iron piece vibrates and sounds. The advantages are long service life and high efficiency. The disadvantages are large distortion and narrow frequency response. Commonly used in early telephone receivers. This technology is mainly used on earplugs nowadays. Since the moving iron pronunciation unit is much smaller than the moving coil pronunciation unit, many high-end earplugs integrate two or even three moving iron pronunciation units, and the sound performance of each frequency band is excellent.

The diaphragm is suspended in the electrostatic field formed by two fixed metal plates (stators) and the electrostatic earphone must use a special amplifier to convert the audio signal into a voltage signal of several hundred volts,

Although electrostatic earphones have various advantages, the technology of this sound unit is only in the hands of a few manufacturers. The basic price of electrostatic earphones on the market is more than 10000 yuan. It is worth mentioning that Winny, a headphone enthusiast in China, has developed the first set of electrostatic headphones in China, becoming a milestone in the history of headphones in China.

The development of headphones is towards wireless and noise reduction. Wireless headphones are more free to use. With the development of science and technology, wireless transmission technology is gradually mature, which ensures the sound quality of wireless headphones. Another reason is the popularity of mobile phone music function and the birth of Bluetooth wireless transmission technology. Bluetooth wireless headset is developing rapidly.

With the increasingly serious noise pollution in the city, ordinary earphones and earplugs can only be used outdoors to increase the volume to cover the noise. In this way, not only can you not enjoy the beautiful music, but also have a great impact on your hearing. The emergence of noise reduction earphones has solved this problem well.

The active noise reduction headset has a noise reducer. The noise reducer uses the microphone to collect the external sound and emit the opposite sound wave to counteract the noise. Today, when people are more and more concerned about their health, noise reduction earphones can better enjoy music outdoors and ensure the health of ears, which is the development direction of earphones in the future. Among the active noise reduction earphones, there are earphones specially designed for travelers with wireless, noise reduction and high sound quality. Bluetooth 3.0 with aptx can provide up to 10 hours of music listening time.
