Adjusting the level of acoustic and haptic output in haptic devices
First Claim
1. An electronic device comprising:
- a feedback surface defining a plane;
an actuator;
a connection member operably connecting the feedback surface to the actuator, wherein the actuator is configured to impart a force to the connection member and the feedback surface, thereby producing a haptic output and an acoustic output; and
an output adjustment mechanism for changing the acoustic output relative to the haptic output for a given force.

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.

13. A method for adjusting a haptic and acoustic output of a haptic device, comprising:
-
applying a force to a feedback surface to produce a first output having a first haptic component and a first acoustic component; changing a physical characteristic of the haptic device; and applying the force to the feedback surface to produce a second output having a second haptic component and a second acoustic component different than the first acoustic component. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method for adjusting a haptic and acoustic output of a haptic device, the haptic device comprising a feedback surface, an actuator, and a connection member operably connecting the feedback surface to the actuator, the method comprising:
-
while the actuator is in a position relative to the feedback surface, actuating the actuator to apply a force to the feedback surface via the connection member, thereby producing a first haptic and acoustic output; translating the actuator to a different position relative to the feedback surface; and actuating the actuator to apply the force to the feedback surface via the connection member, thereby producing a second haptic and acoustic output different from the first haptic and acoustic output.

21. A haptic device comprising:
-
a feedback surface; an actuator configured to produce a force to move the feedback surface; a biasing support operatively coupled to the feedback surface and configured such that a physical characteristic of the biasing support can be changed dynamically to adjust a haptic and acoustic output of the haptic device; and a processing device configured to send a signal causing the physical characteristic of the biasing support to change. - View Dependent Claims (22, 23, 24)
