Abstract:
A leader line of a voice coil from a conductive wire part is drawn out from a part between a diaphragm coupling part and a part disposed in the magnetic gap toward a frame in a non-contact state with a diaphragm. One end side of the second edge made of an elastic body is coupled to a part between a drawing part of the leader line on the voice coil and a part of the voice coil disposed in the magnetic gap. The other end side of the second edge is coupled to the frame. A suspension holder is integrated with the proximity of a coupling part of the second edge to the voice coil. The suspension holder is stuck to the voice coil using an adhesive. The disturbance of the movement of the voice coil can be reduced.
