Abstract
A loudspeaker magnetic circuit system includes an iron a magnetic steel, a spring washer, a voice coil and a U-shaped short-circuit ring. The U-shaped short-circuit ring includes a first ring body and a second ring body, and the voice coil is positioned and movable up and down in a U-shaped groove formed by the first ring body and the second ring body. Through making the short-circuit ring into a U-shaped structure and optimizing the connection relationship between the short-circuit ring and other components such as the spring washer, magnetic steel and iron, the present invention can effectively reduce the harmonic distortion and non-linear distortion of the loudspeaker and improve the overall acoustic performance of the speaker such that the sound quality of loudspeaker is improved.
