Electrostatic Earphone Are Light And Thin Diaphragm
Jun 14, 2017

  Electrostatic Earphone are light and thin diaphragm, polarized by high DC voltage, the energy required for polarization by the AC conversion, but also battery-powered. The diaphragm is suspended in an electrostatic field formed by two fixed metal plates (stator). When the audio signal is loaded on the stator, the electrostatic field changes and vibrates the diaphragm. The single stator can also drive the diaphragm, but the double stator's push-pull form is less distorted. The electrostatic headset must use a special amplifier to convert the audio signal into a voltage signal of several hundred volts, and the transformer can be connected to the output of the power amplifier. Electrostatic Earphone are expensive, not easy to drive, can reach the sound pressure level and no moving coil Earphone, but it's fast response, to reproduce a variety of small details, very low distortion.

  Although the static headset has all the benefits, but the pronunciation of the unit technology is only in the hands of a handful of manufacturers, and now the market price of static Earphone are more than 10,000 yuan.

  Earphone are now showing the development of wireless and noise reduction development. Wireless headset to use more freedom, with the development of science and technology, wireless transmission technology gradually mature, to ensure the wireless headset sound quality. Another reason is the popularity of mobile phone music and the birth of Bluetooth wireless transmission technology, Bluetooth wireless headset is developing rapidly.

  With the city's noise pollution more and more serious, the use of ordinary Earphone in the outdoor earplugs, can only increase the volume to cover the noise, so that not only can not enjoy the wonderful music, their hearing also has a great impact. Noise reduction Earphone appear, a good solution to this problem.
