DETAILED DESCRIPTION OF THE DRAWINGS

Display100includes a front panel102and a display panel104. Front panel102includes audio channels110,112, and114. In an example, display100may include one or more built in speakers to provide an audio output to a user of an information handling system in communication with the display. In certain examples, a different one of the speakers may be located behind a different one of audio channels110,112, and114. In an example, each of the speakers may be a front firing speaker, such that the audio generated from the speaker is provide out the front the display100as shown inFIGS.1and2. For example, a speaker behind audio channel110may provide sound waves120through the audio channel and out the front of display100. Similarly, a speaker behind audio channel112may provide sound waves122through the audio channel and out the front of display100. Additionally, a speaker behind audio channel114may provide sound waves124through the audio channel and out the front of display100. In previous information handling systems, speakers in a display may be down firing speakers such that sound waves from the speakers are provide downward from bottom of the display.

In another example, display100may be an ‘all-in-one’ system, such that the display may include the components to display images, and the components to perform operations of an information handling system, such as information handling system800ofFIG.8. In an example, display100may include additional components without varying from the scope of this disclosure. A portion of display100taken along line A-A will be described with respect toFIG.7below.

Referring now toFIG.2, display100further includes halo portions210,212,214,216, and218. Halo portions210,212,214,216, and218are located behind front panel102, and each of the halo portions may slide between a closed position and an open position as will be described herein. In certain examples, each of halo portions210,212,214,216, and218may be any other type of baffle that captures and redirects an output of bias lighting. Using the described halo portions210,212,214,216, and218provides a predictable medium by which bias lighting may be provided and for which bias lighting for a particular type of display can be specially configured. Each halo portion210,212,214,216, and218is illustrated in the open position.

In an example, a different speaker may be located behind each of halo portions210,214, and218and each speak may be a front firing speaker. In certain examples, the speaker behind halo portion210may align with audio channel110ofFIG.1when the halo portions are in the closed position. Similarly, the speaker behind halo portion214may align with audio channel112ofFIG.1when the halo portions are in the closed position. Also, the speaker behind halo portion218may align with audio channel114ofFIG.1when the halo portions are in the closed position.

In certain examples, the speaker behind halo portion210may provide sound waves120out the front of display100. Similarly, the speaker behind halo portion214may provide sound waves122out the front of display100. Additionally, the speaker behind halo portion218may provide sound waves124out the front of display100. A portion of display100taken along line B-B will be described with respect toFIG.6below.

Referring now toFIG.3, display100further includes a back panel302. In an example, each of halo portions210,212,214,216, and218include a back surface that is part of back panel302. For example, when halo portions210,212,214,216, and218are in the closed position, the back surfaces of each of the halo portions align with back panel302to form a substantially seamless surface to create the back panel.

FIGS.4-5illustrate an exciter component400according to at least one embodiment of the present disclosure. Exciter component400includes electrodes402and404, and a ceramic component406. Electrode402may be in physical communication with a first surface of ceramic component406and electrode404may be in physical communication with a second surface of the ceramic component. As shown inFIG.5, electrodes402and404are on opposite surfaces of ceramic component406.

During operation, electrode402may receive a voltage having a first polarity and electrode404may receive a voltage having an opposite polarity of the voltage applied to electrode404. Based on the polarities of the voltages applied to electrodes402and404, exciter component400may contract and expand. For example, when a positive voltage is applied to electrode402and a negative voltage is applied to electrode404, exciter component400may expand in the directions of arrows502and504. In an example, the expansion of exciter component400in the direction of arrows502and504may create a compressive force on ceramic component406as indicated by arrows506and508. The compressive force in the direction of arrows506and508may cause exciter component400to bend toward electrode402.

In certain examples, when a negative voltage is applied to electrode402and a positive voltage is applied to electrode404, exciter component400may contract in the direction of arrows510and512. In an example, the compression of exciter component400in the direction of arrows510and512may create a tensile stress on ceramic component406as indicated by arrows514and516. The tensile stress in the direction of arrows514and516may cause exciter component400to bend toward electrode404. In certain examples, the bending of exciter component400back and forth from the direction of electrode402to the direction of electrode404may change the direction of air flow, which in turn may generate sound.

FIGS.6and7illustrate a cross section of a portion600of a display, such as display100ofFIG.1, including a halo portion602, a front panel604, a display panel606, and an exciter component608according to at least one embodiment of the present disclosure. Halo portion602may be substantially similar to halo portion214ofFIG.2, front panel604may be substantially similar to front panel102ofFIG.1, display panel606may be substantially similar to display panel104ofFIG.1, and exciter component608may be substantially similar to exciter component400ofFIGS.4and5. Halo portion602includes a back surface610and a reflector plate612.

In an example, exciter component608may be physically attached to reflector plate612of halo portion602. For example, exciter component608may be adhesively attached to reflector plate612. The attachment of exciter component608to reflector plate612may result in the reflector plate being a diaphragm for the exciter component, such that the reflector plate may create an enhanced sound performance within the display. When halo portion602is in an open position, as shown inFIG.6, exciter component608may be positioned beyond front panel604and display panel606.

In an example, as different voltages are applied to the electrodes of exciter component608, the exciter component may bend back and forth as indicated by bidirectional arrow620. In certain examples, the bending of exciter component608may cause reflector plate612to bend the same directions as the exciter component and generate sound from the display. In an example, the combination of exciter component608and the separate diaphragm reflector plate612, may increase multi-channel sound within the display and prevent distortion/interference from each of the exciter components. When halo portion602is beyond front panel604and display panel606, the sound from exciter component608and reflector plate612may be provided to an individual associated with an information handling system without interference from the front panel and the display panel.

Referring now toFIG.7, front panel604includes a top surface702and a display panel mounting component704. At a particular location of front panel604, top surface702may be located a particular distance710from display panel mounting component704. Distance710may create an audio channel712from within the display to a front portion of the display. In an example, audio channel712may be substantially similar to audio channels110,112, and114ofFIG.1.

When halo portion602is in a closed position, as shown inFIG.7, the sound from exciter component608and reflector plate612may be provided within the display. In previous displays, based on the sound being within the display, the different components of the display may interfere with the sound being provided to the user. In an example, exciter component608may be positioned behind audio channel710such that the sound may travel through the audio channel have distance712. In this example, audio channel710may enable the sound produced by exciter component608and reflector plate612to be provided, as illustrated by arrow714, to the user of an information handling system and the display.
