Abstract: A loudspeaker having a compact magnet system that produces an increased magnetic flux. A seat has an outer wall that retains an magnet therein such that a channel is defined therebetween. A plate is positioned on top of the first magnet such that an air gap is created between the plate and the wall. A second magnet is positioned over the plate and an aperture is created axially through the second magnet, the plate, and the first magnet. A yoke having a planar region and a protruding region extending therefrom is position over the second magnet such that the protruding region extends through the aperture and connects with the seat. A voice coil is connected to a diaphragm and is moveably suspended within the gap. Application of an electric current to the voice coils causes movement of the diaphragm due to the magnetic flux created within the gap and thereby produces sound waves.
