AI Technical Summary
Existing loudspeakers have many parts, complex structures, and are cumbersome and inconsistent in assembly. Uneven magnetic field distribution leads to nonlinear distortion of voice coil vibration, and insufficient heat dissipation affects sound quality and sensitivity.
The design employs a dual-ring magnetic field, which integrates the second washer, the second ring magnet, and the PCB circuit board into a pre-assembled structure to form the first assembly. This assembly is then bonded to the base, the first ring magnet, and the first washer to form the second assembly, simplifying the assembly process. The dual-magnet configuration enhances the magnetic field strength and uniformity, and increases the heat dissipation area.
It enables modular pre-assembly of loudspeakers, reduces human error, improves assembly efficiency and product consistency, enhances magnetic field stability, increases voice coil driving force and heat dissipation efficiency, and improves sound quality and sensitivity.
