Abstract: A vibration-damping rectangular magnetic assembly includes a rectangular magnetic assembly and a vibration-damping structure. The rectangular magnetic assembly includes a main magnetic plate, magnetic unit, vibration-damping structure connecting portion and vibration-damping groove. The magnetic unit is disposed at the top of the main magnetic plate. The vibration-damping structure connecting portion and the vibration-damping groove are disposed at the bottom of the main magnetic plate, with the vibration-damping groove disposed outside the vibration-damping structure connecting portion. The vibration-damping structure includes a ring-shaped speaker base butting portion, magnetic assembly butting portion disposed inside the ring-shaped speaker base butting portion, first and second resilient connecting modules connected between the ring-shaped speaker base butting portion and the magnetic assembly butting portion. The magnetic assembly butting portion is connected to the vibration-damping structure connecting portion. The first and second resilient connecting modules are disposed at the vibration-damping groove.

Abstract: A vibration damping loudspeaker includes a sound-generating unit, a magnetic member, an assembly-auxiliary frame and dampers. Aligning units of the assembly-auxiliary frame are coupled to positioning units of the sound-generating unit. The dampers are symmetrically disposed between the magnetic member and the assembly-auxiliary frame. The sound-generating unit and the magnetic member can be quickly and easily mounted in place because of the assembly-auxiliary frame to not only enhance the production yield of the vibration damping loudspeaker but also allow the dampers to function as a buffer between the sound-generating unit and the magnetic member, so as to achieve vibration damping and vibration isolation during the operation of the vibration damping loudspeaker to spare users the discomfort they will otherwise experience for using electronic devices.
