Vibrotactile haptic feedback devices
First Claim
1. A device, comprising:
- a mass;
a first actuator configured to vibrate the mass; and
a coupling disposed between the actuator and the mass or between the mass and a housing, the coupling being a tapered member having a centerline axis, the coupling having a first configuration with a compliance and a second configuration with a compliance, the compliance of the coupling in the first configuration being different from the compliance of the coupling in the second configuration, the actuator being configured to output haptic feedback associated with the first configuration of the coupling and haptic feedback associated with the second configuration of the coupling, the haptic feedback associated with the first configuration of the coupling being different from the haptic feedback associated with the second configuration of the coupling, anda second actuator, the tapered member being coupled to the second actuator, the second actuator being coupled to the housing, the second actuator being configured to rotate the tapered member about its centerline axis to switch between its first configuration and its second configuration.

Abstract
Vibrotactile haptic feedback devices are disclosed. For example, in one embodiment, a device includes: a mass, an actuator configured to vibrate the mass, and a coupling disposed between the actuator and the mass or between the mass and a housing, the coupling having a first configuration with a compliance and a second configuration with a compliance, the compliance of the coupling in the first configuration being different from the compliance of the coupling in the second configuration, the actuator being configured to output haptic feedback associated with the first configuration of the coupling and haptic feedback associated with the second configuration of the coupling, the haptic feedback associated with the first configuration of the coupling being different from the haptic feedback associated with the second configuration of the coupling.

12. A method comprising:
-
outputting a vibration to a device by a first actuator assembly comprising a coupling disposed between an added mass and a suspension the coupling having a first configuration with a compliance and a second configuration with a compliance the coupling being a tapered member having a centerline axis, the tapered member being coupled to a second actuator coupled to the device, the second actuator being configured to rotate the tapered member about its centerline axis to switch between its first configuration and its second configuration; receiving a sensor signal from a sensor configured to measure a resonant frequency of the device; determining, by a processor, a force to apply to the suspension to change the compliance of the suspension based at least in part on the resonant frequency; and applying the force to the suspension to change the compliance. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
