MAGNETIC STIFFNESS REDUCTION FOR AUDIO TRANSDUCERS
This abstract first appeared for US patent application 20250106562 titled 'MAGNETIC STIFFNESS REDUCTION FOR AUDIO TRANSDUCERS
Original Abstract Submitted
aspects of the subject technology relate to stiffness reduction for audio transducers, such as speakers. stiffness reduction can be provided using one or more magnetic structures configured to move with a voice coil and/or a diaphragm of the speaker, and assist in the motion of the voice coil and/or diaphragm via magnetic interaction with one or more magnets of the speaker. in one or more implementations, the one or more magnetic structures may form a tri-stable system with the one or more magnets.
