Abstract

An information handling system may include a keyboard assembly and a display assembly rotatably coupled to the keyboard assembly and comprising a display, a cover mechanically coupled to the display, and a piezoelectric transducer interfaced between the display and the cover and configured to generate sound from the display in response to the display assembly being in a closed position relative to the keyboard assembly and generate sound from the cover in response to the display assembly being in an open position relative to the keyboard assembly.

Claims (37)

1 . An information handling system comprising:

a keyboard assembly; and

a display assembly rotatably coupled to the keyboard assembly and comprising:

a display;

a cover mechanically coupled to the display; and

a piezoelectric transducer interfaced between the display and the cover and configured to generate sound from the display in response to the display assembly being in a closed position relative to the keyboard assembly and generate sound from the cover in response to the display assembly being in an open position relative to the keyboard assembly;

a processor communicatively coupled to the piezoelectric transducer and configured to:

in response to the display assembly being in the open position relative to the keyboard assembly, control the piezoelectric transducer to optimize sound performance of the piezoelectric transducer in the open position; and

in response to the display assembly being in the closed position relative to the keyboard assembly, control the piezoelectric transducer to optimize sound performance of the piezoelectric transducer in the closed position.

2 . The information handling system of claim 1 , further comprising a touch sensor.

3 . The information handling system of claim 2 , wherein the display is interfaced between the touch sensor and the piezoelectric transducer.

4 . The information handling system of claim 2 , wherein the touch sensor is interfaced between the cover and the piezoelectric transducer.

5 . The information handling system of claim 2 , further comprising the processor communicatively coupled to the piezoelectric transducer and the touch sensor and configured to cause the piezoelectric transducer to generate haptic feedback responsive to user interaction sensed by the touch sensor.

6 . The information handling system of claim 2 , wherein the touch sensor is a capacitive sensor.

7 . The information handling system of claim 2 , wherein the touch sensor is integrated within a glass cover for the display.

8 . A method comprising, in an information handling system having a keyboard assembly and a display assembly rotatably coupled to the keyboard assembly and comprising, wherein the display assembly includes a display and a cover mechanically coupled to the display:

generating sound from the display by a piezoelectric transducer interfaced between the display and the cover in response to the display assembly being in a closed position relative to the keyboard assembly;

generating sound from the cover by the piezoelectric transducer in response to the display assembly being in an open position relative to the keyboard assembly;

in response to the display assembly being in the open position relative to the keyboard assembly, controlling the piezoelectric transducer to optimize sound performance of the piezoelectric transducer in the open position; and

in response to the display assembly being in the closed position relative to the keyboard assembly, controlling the piezoelectric transducer to optimize sound performance of the piezoelectric transducer in the closed position.

9 . The method of claim 8 , wherein:

the information handling system further comprises a touch sensor; and

generating haptic feedback by the piezoelectric transducer responsive to user interaction sensed by the touch sensor.

10 . The method of claim 9 , wherein the display is interfaced between the touch sensor and the piezoelectric transducer.

11 . The method of claim 9 , wherein the touch sensor is interfaced between the cover and the piezoelectric transducer.

12 . The method of claim 9 , wherein the touch sensor is a capacitive sensor.

13 . The method of claim 9 , wherein the touch sensor is integrated within a glass cover for the display.

14 . An article of manufacture comprising:

a non-transitory computer-readable medium; and

computer-executable instructions carried on the computer-readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in an information handling system having a keyboard assembly and a display assembly rotatably coupled to the keyboard assembly and comprising, wherein the display assembly includes a display and a cover mechanically coupled to the display:

cause generation of sound from the display by a piezoelectric transducer interfaced between the display and the cover in response to the display assembly being in a closed position relative to the keyboard assembly;

cause generation of sound from the cover by the piezoelectric transducer in response to the display assembly being in an open position relative to the keyboard assembly;

in response to the display assembly being in the open position relative to the keyboard assembly, control the piezoelectric transducer to optimize sound performance of the piezoelectric transducer in the open position; and

in response to the display assembly being in the closed position relative to the keyboard assembly, control the piezoelectric transducer to optimize sound performance of the piezoelectric transducer in the closed position.

15 . The article of claim 14 , further comprising:

the information handling system further comprising a touch sensor; and

the instructions for causing generation of haptic feedback by the piezoelectric transducer responsive to user interaction sensed by the touch sensor.
