ABSTRACT:
A speaker having a diaphragm with an outer peripheral part. A voice coil is disposed within and coupled to the diaphragm, the voice coil supported by a voice coil bobbin with the voice coil having at least two lead wires. The speaker includes a generally cup-shaped frame with the diaphragm disposed inside of the frame so that an outer peripheral part of the diaphragm is coupled to the frame with a damper disposed inside of the cup-shaped frame so that adhesive on the outer part of the damper is used to adhere the damper to the frame. The speaker is completed with an electric relay terminal coupled to the lead wires of the voice coil, a terminal base coupled to the frame, at least two electric connection terminals coupled to the terminal base, one end of each electric connection terminal projecting inside of the space defined by the cup-shaped frame and coupled to the electric relay terminal at a position above a central part of the damper with the lead wires extending the shortest distance between the voice coil and the electric connection terminals projecting inside the frame so that low frequency resonance is avoided when the speaker is in use.
