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.
