Abstract
An audio loudspeaker with an internal magnet geometry motor having a slotted cylinder having closed ends, a pair of oppositely charged magnets sandwiching a top plate and disposed between the closed ends of the cylinder, and a diaphragm assembly having a bobbin with spokes which extend through the slots. Mechanically connecting to the voice coil radially through the cylinder enables the lower suspension component to be places much lower and farther from the upper suspension component, improving stability of the suspension. The closed ends of the motor provide extremely low magnetic reluctance for the magnetic circuits at the respective ends of the motor.
