Moving coil speaker is a common earphone speaker at present. It is basically a small moving coil speaker, driven by the voice coil in a permanent magnetic field and connected with the diaphragm vibration. The coil drives the vibration film to sound under the model current. Moving-coil earphones are mostly driven by the earphone output on audio, and are reliable and durable. They are relatively easy to make, with small distortion and wide frequency response, and their disadvantages are relatively low efficiency.

The four main reasons for choosing moving coil speakers are:

Long history, precipitation of technology
As early as 1877, moving coil loudspeaker was born, which has a history of more than 100 years. The technology of moving coil drive unit is very mature now. At present, the improvement of major earphone manufacturers is mainly focused on the development of permanent magnets with higher magnetic density and more ideal diaphragm materials.

Material improvement, sound quality improvement
The diaphragm of moving coil horn is the most important part in the moving coil unit. Generally speaking, the larger the diaphragm diameter is, the more air can be driven, which is very helpful for the low frequency promotion. The diaphragm structure and material are diverse, and the transparent material similar to silicone is more common.

Stable performance, core technology
With the development of science and technology, the manufacturing industry is gradually finding out the core technology, so that the stability of each product has reached a very high quality.

A more emotional voice

With the higher and higher requirements for sound, headset speakers are changing constantly, which also allows speakers to have innovation and breakthrough, speakers are also constantly innovating materials, so that the sound according to different needs, there are different production materials.
