Voice coil assembly for a speaker
The Journal of the Acoustical Society of America, 1981A voice coil assembly for a speaker comprises a substrate, a spiral pattern coil formed on the substrate, at least one holder fixedly secured to the periphery of the substrate, and at least one metallic layer attached to said substrate. The metallic layer facilitates the dissipation of the heat generated by the voice coil, while a pair of metallic ...

Planar fabrication of a mesoscale voice coil actuator
2014 IEEE International Conference on Robotics and Automation (ICRA), 2014Mesoscale robots are devices with characteristic dimensions in the centimeter to millimeter scale, with feature sizes ranging from millimeters to micrometers. Due to the physics involved in scaling down conventional motors, such robots frequently require novel approaches to actuation. Actu- ation can have a very significant effect on robot performance,

Voice coil based hopping mechanism for microrobot
2009 IEEE International Conference on Robotics and Automation, 2009Hopping is a very efficient locomotion method for a robot in an unconstructed environment or a complicated terrain. Small hopping robots have many interesting properties in comparison to the larger ones. However, relatively little research has been reported on hopping microrobot, while most of existing designs of hopping robots are not suitable to ...
