摘要：
A loudspeaker having a magnetizable pole piece, a voice coil member surrounding the pole piece with a portion of magnetic gap and connected to a vibratable diaphragm, and a damper supporting the voice coil member, is characterized in that an elastic member is provided between the pole piece and the voice coil member in the magnetic gap wherein an elastic member is made of an elastic material having an elastic constant substantially 1.5 times or more than that of the damper. In addition, the elastic material is made of a silicone rubber.
