Abstract

In an embodiment an apparatus includes a display panel and a speaker module. The panel has a display layer for displaying images and defines a plurality of apertures penetrating through at least the display layer. The speaker module includes a diaphragm arranged substantially parallel to the display layer. Sound from the speaker diaphragm is directed outside a device through the apertures and the display layer is configured for displaying at least one virtual image in relation to generated sound waves wherein the display panel is acoustically transparent.

First claim

The invention claimed is:

1. An apparatus, comprising:
a display;
a display speaker which comprises at least one display element of the display, wherein the at least one display element is configured to generate sound waves from the display at a plurality of sound producing locations within an effective area of the display;
at least one processor; and
at least one non-transitory memory including computer program code, the at least one non-transitory memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
determine at least one location out of the plurality of sound producing locations within the effective area of the display to produce sound while an application is operating within the apparatus, wherein the at least one location is determined based on an indication from a user interface, wherein the indication from the user interface is configured to indicate the at least one location for sound production, wherein the indication from the user interface is received while the application is operating within the apparatus;
cause display of at least one image on the display at the determined at least one location at least to indicate the produced sound is substantially coming from the determined at least one location; and
cause the display speaker to generate sound waves from the display at the determined at least one location to produce the sound, wherein, when one or more display elements of the at least one display element, corresponding to the at least one determined location, are driven, the one or more display elements are caused to generate the sound waves based on the indication.

2. The apparatus according to claim 1 , wherein the at least one image is at least one of the following:
an image to represent a sound outlet for the generated sound waves; or
an image to indicate a location of the display speaker.

3. The apparatus according to claim 1 , wherein the display speaker is configured to actuate the display so as to convert an electrical signal into a motion of the display.

4. The apparatus according to claim 1 , wherein the display is acoustically transparent, and wherein the display comprises at least one aperture, wherein the at least one aperture is substantially invisible to the naked eye.

5. The apparatus according to claim 1 , further comprising a sensor configured to receive a sensor input, and wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to control at least one of:
the display speaker; or
the at least one image

dependent on the generated sound waves.

6. The apparatus according to claim 5 , wherein the display speaker comprises at least two segments configured to generate sound waves independently, wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
drive the at least two segments dependent on the sensor input.

7. The apparatus according to claim 6 , wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
control the at least two segments to generate sound waves which interact with one another to form an interference pattern to determine the directionality and/or loudness of the generated sound waves.

8. The apparatus according to claim 1 , further comprising a touch sensor configured to detect touch inputs, wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to control at least one of:
the display speaker; or
the at least one image

dependent on the generated sound waves.

9. The apparatus according to claim 8 , wherein the display speaker comprises at least two segments, and wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
in response to touch sensor detection of a touch input, drive the segment closest to a position of the touch input.

10. The apparatus according to claim 1 , wherein the display comprises one of:
an organic LED display;
an inorganic LED;
an electrochromic;
an electrophoretic;
a LCD display; or
an electrowetting display.

11. The apparatus according to claim 1 , wherein the display speaker is one of:
a piezo-electric speaker;
an electrodynamic speaker; or
an electrostatic speaker.

12. The apparatus according to claim 1 , wherein the display comprises a haptic device configured to provide tactile feedback.

13. The apparatus according to claim 1 , wherein the display speaker associated with the display is disposed within one of:
a mobile electronic device;
an automobile dash-mount display;
a television; or
a personal computer of the type desktop, laptop, palmtop or tablet.

14. The apparatus of claim 1 , wherein the display speaker generated sound waves originate at the display.

15. The apparatus of claim 1 , wherein the at least one image overlays a main image being displayed on the display.

16. The apparatus of claim 1 , wherein the at least one determined location comprises a number of the plurality of sound producing locations, wherein the number is determined based on the indication.

17. The apparatus of claim 1 , wherein the indication from the user interface comprises a touch input to the display, wherein the touch input is detected at a respective location of the display corresponding to the at least one determined location.

18. The apparatus of claim 1 , wherein the indication comprises a parameter for controlling the generating of the sound waves from the display at the at least one determined location.

19. A method, comprising:
determining at least one location out of a plurality of sound producing locations within an effective area of a display to produce sound while an application is operating within an apparatus comprising a display speaker which comprises at least one display element of the display, wherein the at least one display element is configured to generate sound waves from the display at the plurality of sound producing locations, wherein the display is configured to display images;
wherein the at least one location is determined based on an indication from a user interface, wherein the indication from the user interface is configured to indicate the at least one location for sound production, wherein the indication from the user interface is received while the application is operating within the apparatus;
causing display of at least one image on the display at the determined at least one location at least to indicate the produced sound is substantially coming from the determined at least one location; and
causing the display speaker to generate sound waves from the display at the determined at least one location to produce the sound, wherein, when one or more display elements of the at least one display element, corresponding to the at least one determined location, are driven, the one or more display elements are caused to generate the sound waves based on the indication.

20. The method as claimed in claim 19 , further comprising determining an input to the display via a sensor; and controlling at least one of:
the display speaker; or
the at least one image.

21. The method as claimed in claim 19 , wherein the at least
