Embodiment Construction

[0022] The present disclosure describes haptic devices that include haptic feedback actuators that impose haptic effects on a user via a user interface, human-machine interface, or other portion of a user device on or in which the actuator resides. In particular, embodiments of the haptic devices described herein may be configured to apply haptic effects to a touch-sensitive surface of a user device. In some embodiments, the touch-sensitive surface may be part of a display device, where the display device may include both a visual output mechanism and a touch-sensitive input mechanism. Thus, haptic feedback can be applied in user equipment, such as electronic handheld devices, for providing a rich sensory experience to the user.

[0023] While many of the examples described herein relate to touch screen devices, it should be understood that this disclosure also encompasses other types of human-machine interfaces involving touch-sensitive structures. Furthermore, other feature...

Abstract

This openness involves tactile equipment with a linear resonance carrier.A type of tactile output device, including an actor configured to generate a touch effect, and the configuration to transmit the driver signal to the actor and transmit the brake signal to the actor at the same time before the driving signal is terminated or at the same time.processor.The brake signal has the same frequency as the resonance frequency of the actor and is reversed to the drive signal.

Description

technical field [0001] The present invention relates to linear resonant actuators for haptic devices. Background technique [0002] Manufacturers of electronic equipment strive to produce rich interfaces for users. Conventional devices use visual and auditory cues to provide feedback to the user. In some interface devices, kinesthetic feedback (such as active and resistive force feedback) and / or tactile feedback (such as vibration, texture, and heat) are also provided to the user, collectively referred to more generally as "haptic feedback" or "haptic feedback." Effect". Haptic feedback can provide cues that enhance and simplify user interfaces. In particular, vibration effects, or vibrotactile haptic effects, can be useful in providing cues to users of electronic devices alerting them to special events or in providing realistic feedback in simulated or virtual environments that results in greater sensory immersion. [0003] To generate vibration effects, many devices ut...
