Haptic feedback devices

摘要

A haptic feedback device (20, 20′, 20″) comprises a stationary frame (40); a carrier (42) configured for at least one degree of motion relative to the stationary frame; a user interface (44) mounted on the carrier and configured to receive a human impulse; a set (46) of pole pieces; and, a suspension system (48). The haptic actuator (46) comprises a first pole piece (80) mounted to the stationary frame (40); a second pole piece (82) mounted to the carrier (42); and, an electromagnetic coil (84) carried by one of the first pole piece and the second pole piece. The first pole piece and the second pole piece are separately mounted to define an air gap (90) therebetween in a first direction when the electromagnetic coil is not energized, the first direction corresponding to the at least one degree of motion. The suspension system (48) is mechanically separated from both the first pole piece (80) and the second pole piece (92).

主权项

1. An actuatorless haptic feedback device comprising:
a stationary frame comprising a first pole piece directly mounted thereto; a carrier configured for at least one degree of motion relative to the stationary frame, the carrier comprising a second pole piece directly mounted thereto; a user interface mounted on or comprising the carrier and configured to receive an impulse; an electromagnetic coil carried by one of the first pole piece and the second pole piece, the electromagnetic coil being selectively energized as a result of receipt of the impulse; the first pole piece and the second pole piece being separately located relative to the stationary frame and the carrier, respectively, to define an air gap therebetween in a first direction when the electromagnetic coil is not energized, the first direction corresponding to the at least one degree of motion; a suspension system being configured to connect the carrier to the stationary frame and to allow relative movement between the carrier and the stationary frame in the first direction when the electromagnetic coil is energized to drive the second pole piece toward the first pole piece at the gap; wherein the carrier and the stationary frame are connected to one another by the suspension system but not by an intermediate actuator component which comprises the first pole piece and the second pole piece; wherein the first pole piece and the second pole piece are not carried by a distinct actuator unit but are respectively directly mounted to the stationary frame and the carrier; wherein the suspension system is mechanically separated from both the first pole piece and the second pole piece.
