Description
Technical Field
The utility model relates to the technical field of speakers, in particular to a hat-shaped Faraday ring structure.
Background
When a diaphragm vibrates to produce sound, a current driving the voice coil will cause an additional but opposite current, the so-called "Back EMF", which modulates the magnetic field in the air gap, resulting in significant second harmonic distortion. The most common solution to this problem is to make the metal near the voice coil of a material with a sufficiently high magnetic permeability, but high magnetic permeability metals are relatively expensive. A technical scheme of magnetic field modulation is called a short circuit ring or a Faraday ring, wherein a conductive layer such as copper is covered on the top end of a magnetic conduction column, the Faraday ring scheme is relatively low in price, but the conductive layer such as copper is plated on the magnetic conduction column, the process is complex, and oxidation failure is easy to occur. The other ring-shaped Faraday ring is arranged at the bottom of the magnetic conductive column and has the same function as the plating layer. The brand new loudspeaker is manufactured through a debugging stage, and the coating Faraday ring or the annular Faraday ring is additionally arranged, so that the whole part can be scrapped after the debugging is not up to standard once the coating Faraday ring or the annular Faraday ring is additionally arranged. The plating Faraday ring or the annular Faraday ring is not additionally arranged in the debugging stage, and the debugging effect is influenced, so that the improvement is needed.
