Adjusting the level of acoustic and haptic output in haptic devices
First Claim
1. An electronic device comprising:
- a component defining a planar feedback surface along an exterior of the electronic device; and
an actuator system operably coupled to the component and configured to move the component to simultaneously produce a haptic output of a first frequency and an audio output of a second frequency that is different than the first frequency, the actuator system comprising;
a first actuator configured to produce in-plane movement of the component at the first frequency to produce the haptic output; and
a second actuator configured to produce out-of-plane movement of the component at the second frequency to produce the audio output.

Abstract
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.

8. A haptic device for an electronic device, comprising:
-
an input member defining a planar input surface of a touch-sensitive device; a first actuator coupled to the input member and configured to produce in-plane movement of the input member at a first frequency to produce a haptic output; and a second actuator coupled to the input member and configured to produce out-of-plane movement of the input member at a second frequency, different from the first frequency, to produce an audio output. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for producing a haptic and acoustic output via an electronic device, comprising:
-
sending a first signal to a first actuator that is coupled to a planar input member of a touch-sensitive input device and configured to produce in-plane movement of the planar input member, thereby producing a haptic output corresponding to the first signal; sending a second signal to a second actuator that is coupled to the planar input member and configured to produce out-of-plane movement of the planar input member, thereby producing an audio output corresponding to the second signal;
whereinthe second signal has a different frequency than the first signal. - View Dependent Claims (16, 17, 18, 19, 20)
