Moving-iron earphone, inductor and damping short-circuit ring of transformer

Abstract

The invention relates to a moving-iron earphone, an inductor and a damping short-circuit ring of a transformer. An improved technology can be used for the damping short-circuit ring of the moving-ironearphone or the inductor and the transformer, particularly belongs to the damping short-circuit ring of the moving-iron earphone, and can improve tone quality and transparency. The method can also beused for inductance and the transformer of pulse signals to improve front and back edge characteristics and improve signal-to-noise ratio. The damping short-circuit ring is sleeved near a coil for generating the magnetic field, such as the outer side, so that the performance can be improved.

Description

technical field

[0001] The invention relates to an improved technology belonging to moving iron earphones, inductors and transformers, and can be used for sound quality or performance improvement of moving iron earphones, inductors and transformers. Background technique

[0002] Moving-iron earphones are widely used, and are known for their high resolution, but the sound bottom is easy to be thin, sharp, and hard, and suffers from human scale problems. Contents of the invention

[0003] In the 201810390443.4 damping short-circuit ring for electromagnetic driver that I applied for earlier, I proposed a short-circuit ring with damping for electromagnetic driver speakers and earphones. The damping can be mapped onto the voice coil of a speaker or headphone by the principle of a loosely coupled transformer. The additional tail vibration of the damping voice coil is the relaxation oscillation, which improves the sound quality. In the test, it was found that the damping short-...
