Embodiment Construction

[0028] An example embodiment implementing the invention is a combined speaker and display where the speaker is located behind the display and radiates sound through an acoustic hole or aperture penetrating the display. A particularly advantageous display for use in this way uses inorganic LEDs that will enable the placement of acoustic holes or holes between pixels. In the exemplary embodiment detailed below, the holes are smaller than a pixel in order to ensure that the acoustic holes are not visible to the naked human eye. As a specific but non-limiting example, these acoustic cavities / holes have an average diameter of less than 0.06mm. By combining the speaker with the display itself, the size of the speaker's diaphragm is no longer restricted due to size and space constraints due to user preference for large displays as noted in the background section above, or due to low priority given to sound quality by product designers. forced even smaller. In the exemplary embodime...

Abstract

In one embodiment, an apparatus includes a graphic display panel and a speaker. The panel has a display layer for displaying images and defines a plurality of holes penetrating at least the display layer. The speaker includes a diaphragm arranged substantially parallel to the display layer. Sound from the speaker diaphragm is directed out of the host device through the holes. Speakers can be electret or piezoelectric speakers for thinness. There may be holes on the opposite side of the host device case for a dipole pattern that is directional and gives acoustic privacy to the user, or a rear acoustic cavity for a monopole pattern that is wider Disperse the sound. One illustrated embodiment is selectable between monopole and dipole. The size and total area of ​​the apertures determine the acoustic resistance, so a method for determining them from the physical parameters of the display panel is described.

Description

technical field [0001] The exemplary, non-limiting embodiments of the present invention generally relate to graphics and graphics displays such as may be found in portable music devices or wireless radios, as well as in larger consumer electronic devices such as televisions and desktop / laptop personal computers. Panel combination audio transducer / speaker. Background technique [0002] This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may include concepts that may be explored, but not necessarily concepts that have been previously conceived or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] Especially for portable products, such as mobile phones, the consumer product industry is driving towards slimmer designs and...
