  • Transducer With Variable Compliance
    Publication number: 20130156254
    Abstract: A transducer utilizes a sound-producing member positioned in the area of magnetic flux concentration between magnetic poles of opposite polarity. The sound-producing member is variably vibratable in a magnetic structure between the poles to generate acoustic waves, and an acoustic conduit carries the acoustic waves through the magnetic poles e to a location outside the magnetic structure.
