A support of a thin-type mini loudspeaker is disclosed. A thickness of the thin-type mini loudspeaker is lower than 10mm. The support comprises a body, two lead wire racks, two damping colloids and two electric conductors, wherein the body possesses a magnetic back component fixing hole; the magnetic back component fixing hole is used to fix a magnetic back component; the magnetic back component is superposed on a voice coil; the voice coil possesses the two lead wires; the two lead wire racks are arranged on the body and possess lead wire accommodation grooves; the two damping colloids are arranged on the lead wire accommodation grooves; the two electric conductors are arranged on the body and are electrically connected to the lead wires; the lead wire racks are located between the magnetic back component fixing hole and the electric conductors; and the lead wires are arranged on the damping colloids in the lead wire accommodation grooves and the electric conductors and then are in an outer convex arc shape. By using the assembling method of the lead wires of the thin-type mini loudspeaker, the two lead wires of the voice coil are assembled to the support. Therefore, in the invention, an outgoing line end of the voice coil can be directly taken as the lead wire and a brocade silk thread does not need to be additionally used as the lead wire.
