Disclosed herein are methods and systems for providing haptic output and audio output on computing devices using the same haptic device and methods for calibrating the same. To produce the haptic and audio output, the computing device receives a profile of a desired output waveform that is to be provided by the haptic device. Using the desired output waveform, an input waveform is generated. Once the input waveform that will produce the desired output waveform is generated, the input waveform may be calibrated to account for various structural components of the haptic device and may also be combined with an audio waveform. The input waveform is then provided to the haptic device.

Calibration of haptic devices

An electronic device can include one or more actuators. The actuator or actuators may be operably connected to a feedback surface. Movement is produced in at least one actuator that causes an audio output. The movement in the actuator(s) by itself may produce the desired audio output. The movement in the actuator(s) can produce a force in at least one direction that produces movement in the feedback surface, and the movement in the feedback surface produces audio output. The movement in the actuator may also provide a haptic output to a user.

Feedback device in an electronic device

A haptic device in an electronic device includes a feedback surface, one or more actuators, and a connection member connected between the feedback surface and each actuator. At least one actuator produces an attracting or repelling force that creates movement in the connection member and the feedback surface. An acoustic and a haptic output of the haptic device can be adjusted at least in part by producing an out of plane movement in the feedback surface, by changing a cross-sectional area of at least a portion of the connection member, by changing dynamically one or more biasing supports disposed below the feedback surface, and/or by changing at least one waveform characteristic of a haptic input signal received by at least one actuator.
