## Abstract

A portable electronic device comprising a display, an actuator actuatable to impart a force on the display, an input device moveable from a first position in which the input device is disengaged from the display to a second position in which the input device is engaged with the display, wherein when the input device is moved to the second position, the actuator is actuated to provide tactile feedback to the input device through the display.

## Claims

### Claim 1

A portable electronic device comprising:
a housing;
a touch-sensitive display including a display and a display support tray supporting the display and housed by the housing;
an actuator disposed in the housing and actuatable to impart a force on the touch-sensitive display;
a physical key disposed in a sidewall of the housing and comprising a push button that is biased into a first position in which the push button is out of contact and is thereby disengaged from the display support tray at an end of the touch-sensitive display, and moveable, by depression of the push button, to a second position in which the push button contacts the display support tray and is thereby engaged with the display support tray at the end of the touch-sensitive display, wherein when the push button is moved to the second position, the actuator is actuated to provide tactile feedback that is transferred from the display support tray at the end of the touch-sensitive display, to the push button.

### Claim 2 (depends on 1)

The portable electronic device of claim 1, wherein when the push button is in the first position, tactile feedback is not provided to the push button.

### Claim 3 (depends on 1)

The portable electronic device of claim 1, wherein the push button provides an input signal to a processor when moved to the second position.

### Claim 4 (depends on 1)

The portable electronic device of claim 1, wherein the display support tray at the end of the touch-sensitive display is received in a groove of the push button when in the second position.

### Claim 5 (depends on 1)

The portable electronic device of claim 1, comprising a switch that is activated when the push button is moved to the second position.

### Claim 6 (depends on 5)

The portable electronic device of claim 5, wherein the switch provides an input signal to a processor when activated.

### Claim 7 (depends on 1)

The portable electronic device of claim 1, wherein the actuator comprises at least one piezoelectric actuator.

### Claim 8

A method of operating an electronic device to provide tactile feedback, the method comprising:
detecting input from a switch that is activated by a physical key disposed in a sidewall of a housing of the electronic device,
the physical key comprising a push button that is moved, by depression of the push button from a first position into which the push button is biased and in which the push button is out of contact and is thereby disengaged from an end of a display support tray of a touch-sensitive display to a second position in which the push button is in contact with and is thereby engaged with the display support tray at the end of the display;
actuating an actuator in response to detecting input from the switch to impart a force on the display, which force is transferred from the display support tray at the end of the touch-sensitive display, to the push button.

### Claim 9 (depends on 8)

The method according to claim 8, comprising discontinuing actuating the actuator when the switch is deactivated.
