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.

Abstract: A signal transmission structure for speaker includes a base having two outgoing lead grooves provided on the same side thereof; a magnet member arranged on the base; a voice coil movably disposed over the magnet member; two tinsel leads respectively having an end connected to two opposite sides of the voice coil and another end set in the two outgoing lead grooves; and a signal connection board disposed in the base with two tinsel lead welding pads and two hook-up wire welding pads provided on a top and a bottom surface thereof, respectively. The tinsel lead welding pads are located between the voice coil and the outgoing lead grooves, allowing the two tinsel leads to be separately welded thereto. With the above signal transmission structure for speaker, welding of tinsel leads and hook-up wires thereto can be conveniently performed to reduce labor and time costs.
