Abstract
A speaker and its manufacturing method capable of reducing a man power required for mounting an input terminal and improving the product quality. The speaker manufacturing method uses a damper with a conductive member made of flat knitted tinsel wires loaded on or in a woven cloth. A terminal ring made of insulating material is mounted on the damper with the conductive member at its adhesive margin formed on the outer circumference portion. Input terminal lugs are mounted on the terminal ring. A voice coil is mounted on the damper with the conductive member and terminal ring. Input copper foil electrodes formed on the outer circumference of a coil bobbin of the voice coil is electrically connected to the end portions of the flat knitted tinsel wires extending to the inner hole of the damper with the conductive member. The terminal lugs are electrically connected to the ends of the flat knitted tinsel wires extending to the outer circumference of the damper with the conductive member. The coupling area between the damper with the conductive member and the voice coil or coil bobbin is adhered by adhesive or the like to form an integrated ring assembly. The ring assembly is supplied to a speaker manufacturing line to assemble a speaker.
