Multi-coil voice coil motor and systems for providing haptic feedback

Abstract

A multi-coil voice coil motor (VCM) may be configured to be used as a haptic actuator for providing haptic feedback to a user. When implemented in a handheld controller having one or more controls, the multi-coil VCM may be configured to provide haptic feedback to a user of the controller. The multi-coil VCM may include a housing, multiple concentric coils, and a magnet coupled to the housing. The multiple concentric coils may include a first coil disposed on a first support coupled to the housing and a second coil disposed on a second support coupled to the housing, wherein the multiple concentric coils may have different diameters to allow for the concentricity of the coils. A system may include one or more haptic actuators, such as the multi-coil VCM, the haptic actuator(s) being configured to provide haptic feedback by causing at least a portion of a finger-operated control(s) to vibrate.
