Electronic device having a tuned resonance haptic actuation system
First Claim
1. An electronic device, comprising:
- an enclosure;
a display positioned with the enclosure and defining a front face of the electronic device; and
a haptic actuator positioned within the enclosure and comprising;
a housing comprising a wall having a thickness between about 100 microns and about 500 microns;
a movable mass positioned within the housing and configured to move within the housing to cause the haptic actuator to produce a vibrational response including;
a first component within a frequency range; and
a second component outside of the frequency range and providing a haptic output portion of the vibrational response; and
a tuning feature incorporated with the wall and configured to reduce the first component of the vibrational response while substantially maintaining the haptic output portion of the vibrational response, the tuning feature defined by a recess having a depth between about 5 microns and about 10 microns into the wall.

Abstract
An electronic device includes an enclosure, a display positioned with the enclosure and defining a front face of the electronic device, and a haptic actuator positioned within the enclosure. The haptic actuator includes a housing comprising a wall and a movable mass positioned within the housing and configured to move within the housing to cause the haptic actuator to produce a vibrational response. The vibrational response includes a first component within a frequency range and a second component outside of the frequency range and providing a haptic output portion of the vibrational response. The haptic actuator also includes a tuning feature incorporated with the wall and configured to reduce the first component of the vibrational response while substantially maintaining the haptic output portion of the vibrational response.

6. An electronic device, comprising:
-
an enclosure; a display positioned with the enclosure and defining a front face of the electronic device; and a haptic actuator comprising; a housing comprising a wall; a movable mass positioned within the housing and configured to move relative to the housing to impart a force on the housing, thereby causing the haptic actuator to produce a haptic output that is part of a vibrational response of the haptic actuator; and a channel formed in an exterior surface of the wall and comprising a first portion extending along a first direction and a second portion extending along a second direction different than the first direction, the channel having a width between about 100 microns and about 2.0 mm. - View Dependent Claims (7, 8, 9, 10, 19, 20)

11. An electronic device, comprising:
-
an enclosure; a display positioned with the enclosure and defining a front face of the electronic device; and a haptic actuator attached to an internal structure of the electronic device and configured to produce a vibrational response including at least an audible first component within a frequency range between about 1 kHz and about 5 kHz and a haptic second component below about 1 kHz, the haptic actuator comprising; a movable mass; and a housing at least partially enclosing the movable mass and comprising a tuning feature configured to attenuate the audible first component of the vibrational response. - View Dependent Claims (12, 13, 14, 15, 16, 17)
