主权项

1. An audio speaker, comprising:
a bottom plate having a support face and a recess, wherein the recess includes a recessed face below the support face, and wherein the bottom plate includes a first magnetic material having a first magnetic saturation level; a center magnet on the support face and over the recess; a lateral magnet on the support face and over the recess, the lateral magnet radially separated from the center magnet by a magnet gap; a voicecoil for driving a diaphragm, the voicecoil aligned with the magnet gap; and a magnetic insert in the recess on the recessed face, the magnetic insert below the lateral magnet and the center magnet to form a magnetic flux path from the lateral magnet to the center magnet, wherein the magnetic insert includes a second magnetic material having a second magnetic saturation level greater than the first magnetic saturation level.
