    Abstract: Various embodiments of the invention pertain to augmented performance synchronization systems and methods. According to some embodiments of the invention, an audio waveform may be used to generate one or more haptic waveforms for one or more electronic devices. The haptic waveforms may be generated based on any of a number of factors, including features of the audio waveform, capabilities of the haptic actuators performing the haptic waveforms, the number, type and location of devices having haptic actuators, and the like. The haptic waveforms may be synchronized with performance of the audio waveform to provide an augmented listening experience to a user.

    Abstract: Haptic interfaces are described. One haptic interface includes a piezoelectric body and first and second electrodes coupled to the piezoelectric body. The haptic interface also includes a control circuit. The control circuit includes a haptic actuator, a haptic sensor circuit, and an overcurrent protection circuit. The haptic actuator circuit is coupled to the first electrode and configured to charge the piezoelectric body. The charging causes the piezoelectric body to provide a haptic output. The haptic sensor circuit is coupled to the second electrode and configured to sense an electrical change at the second electrode. The electrical change is related to a haptic input received by the piezoelectric body. The overcurrent protection circuit is coupled to the second electrode and configured to limit a current flow into the haptic sensor circuit while the haptic actuator circuit is charging the piezoelectric body.

    Abstract: Disclosed herein are electronic devices having piezoelectric haptic actuators to generate haptic output. The haptic actuators can be configured as a beam with a bendable material layer and a piezoelectric material layer the cause the beam to bend. The bending force can be increased by coupling a magnet to the beam and positioning a ferritic plate near the magnet. Alternatively, a ferritic plate can be attached to the beam, with the magnet positioned apart from, but near, the plate. The haptic actuator can have a two-sided piezoelectric configuration, having a piezoelectric layer on each side of the bendable material layer. A two-sided piezoelectric configuration can have a second magnet and ferritic plate pair on a side of the beam opposite the first. The haptic actuator may use electromagnets.
