Analysis and Design of Micro-Actuator for Loudspeaker

A new thin amorphous panel miniaturization actuator will be expected to improve or develop at low fundamental frequency with high quality acoustic output in this paper, modeled using the magnetic energy by the 3D FEM (finite element method). The computation model analysis will be evaluated and implemented by experiments. As the unique concerns is miniaturization for the loudspeaker on commercial products, micro-actuator will provide a potential solution to meet the requirement of miniaturization for the loudspeaker with flat panel speaker technology, which operates under bending wave principle, and exploits the resonance of the panel instead of the traditional piston motion to produce sound
