HAPTIC ACTUATOR INCLUDING SLIDABLY COUPLED MASSES INCLUDING COILS AND RELATED METHODS

摘要

A haptic actuator may include a housing having a top and a bottom, and first and second permanent magnets carried by the top and bottom, respectively, of the housing. The haptic actuator may also include a field member carried by the housing. The field member may include a coil between the first and second permanent magnets, first and second ends, and a first mass between the first end and the coil, and a second mass between the second end and the coil. A first shaft may slidably couple the first mass to the housing, and a second shaft may slidably couple the second mass to the housing. The haptic actuator may also include a first set of biasing members between the first end of the field member and the housing and a second set of biasing members between the second end of the field member and the housing.

1. A haptic actuator comprising:
a housing having a top and a bottom; first and second permanent magnets carried by the top and bottom, respectively, of the housing; a field member carried by the housing and comprising
at least one coil between the first and second permanent magnets,first and second ends, anda first mass between the first end and the at least one coil, and a second mass between the second end and the at least one coil; a first shaft slidably coupling the first mass to the housing; a second shaft slidably coupling the second mass to the housing; a first set of biasing members between the first end of the field member and the housing; and a second set of biasing members between the second end of the field member and the housing.
