Abstract
Velocity detection is the crucial step for motion feedback and control. A dynamic loudspeaker can be conceptualized as a motion conductor within magnetic field. This invention calculates the velocity of a motion conductor, uses operational amplifier to emulate the calculation and realize the velocity detection.
