| 摘要 |
The present invention relates to synchronized vibration devices (620) that can provide haptic feedback to a user. A wide variety of actuator types may be employed to provide synchronized vibration, including linear actuators (100), rotary actuators (300), rotating eccentric mass actuators (304), and rocking or pivoting mass actuators (400, 490). A controller (502) may send signals to one or more driver circuits (504) for directing operation of the actuators. The controller may provide direction and amplitude control (508), vibration control (512), and frequency control (510) to direct the haptic experience. Parameters such as frequency, phase, amplitude, duration, and direction can be programmed or input as different patterns suitable for use in gaming, virtual reality and real-world situations. |
