Embodiment Construction

[0021] as attached figure 2 As shown, a five-layer damping short-circuit ring is added to the tail of the commercially available moving iron earphone. The results of the subjective listening test are: the harshness of the sound has improved significantly, the sound is much rounder, the background is clean and transparent, the sound image is specific and transparent, the music appeals well, and the bass is solid and powerful.

Abstract

Moving-iron earphones and damped short-circuit rings for inductors and transformers. An improved technology that can be used for damping short-circuit rings of moving-iron earphones or inductors and transformers, and specifically belongs to the damping short-circuit ring of moving-iron earphones, which can improve sound quality and transparency. It can also be used as an inductor and transformer for pulse signals to improve front and rear edge characteristics and improve signal-to-noise ratio. It can also be used in a pulsed magnetic field generating device, and the performance can be improved by installing a damping short-circuit ring near the coil that generates the magnetic field, such as on the outside.

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-...
