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.

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.

Abstract: A support frame for a thin mini speaker structure thinner than 10 mm includes a main body having a fixing hole, into which a magnet assembly is mounted to locate below a voice coil; two electrically conductive members disposed on the main body; two lead wire holders disposed on the main body between the fixing hole and the electrically conductive members and each defining a lead wire receiving groove thereon; a first damping colloid applied into the lead wire receiving grooves. Two lead wires of the voice coil are set in the first damping colloid in the lead wire receiving grooves and the electrically conductive members to respectively present an outward curved shape. A thin mini speaker lead wire assembling method is also introduced. With the above support frame and method, two ends of the voice coil windings can be directly used as lead wires to save additional tinsel leads.
