Abstract
The utility model provides a novel structure of a loudspeaker magnetic loop circuit. The structure comprises a top magnetic conductive portion, a bottom magnetic conductive portion, at least one magnetic conductive disc, and a plurality of magnets. The top magnetic conductive portion and the bottom magnetic conductive portion are both plate bodies. The magnetic conductive disc is arranged between the top magnetic conductive portion and the bottom magnetic conductive portion. A space for placing the magnets is formed by the magnetic conductive disc and the top magnetic conductive portion while another space for placing the magnets is formed by the magnetic conductive disc and the bottom magnetic conductive portion. When the magnets and an annular voice coil are driven , generated magnetic force moves the annular voice coil in parallel so that the annular voice coil pushes a tapered basin to vibrate a vibrating diaphragm. Therefore, air is pushed to generate voice. When the thicknesses of magnets are limited, the magnets lengthened to increase the volumes of the magnets. Therefore, magnetic force loss is compensated and poor loudspeaker efficiency is prevented.
