Technical Field

[0002] This application generally relates to techniques for redirecting acoustic radiation from a display device and correspondingly controlling audio output from the display device to enhance the user experience. Summary of the Invention

[0003] Various aspects of this disclosure relate to devices, systems, and methods for redirecting acoustic radiation from a display device and correspondingly controlling audio output from the display device to enhance the user experience, for example, by providing acoustic radiation in additional / different directions when the display device is used with an auxiliary speaker.

[0004] In one aspect of this disclosure, a method for generating audio content is provided. The method may include using an electronic processor to generate first audio content to be output by a speaker of a display device. The first audio content may be generated based on device data of the display device indicating that the speaker is in a first direction relative to the main radiation axis of the display screen. The method may also include using the electronic processor to determine the presence of an auxiliary speaker configured to output audio associated with the display device. The method may further include using the electronic processor and based on determining the presence of the auxiliary speaker to determine that the speaker's main radiation axis relative to the display screen has been modified to a second direction different from the first direction. The method may further include, in response to determining that the speaker's main radiation axis relative to the display screen has been modified to the second direction, modifying the device data of the display device indicating that the speaker is in the second direction relative to the main radiation axis of the display screen. The method may also include using the electronic processor to generate second audio content to be output by the speaker. The second audio content may be generated based on the device data of the display device indicating that the speaker is in the second direction relative to the main radiation axis of the display screen. Because the speaker's main radiation axis relative to the display screen has been modified from the first direction to the second direction, the second audio content may be generated differently from the first audio content.

[0005] In addition to any combination of the features described above, the first direction of the speaker relative to the main radiation axis of the display screen may be downward or sideways. In addition to any combination of the features described above, generating the first audio content may include generating the first audio content to provide a portion of stereo audio when the auxiliary speaker is not present. In addition to any combination of the features described above, the second direction of the speaker relative to the main radiation axis of the display screen may be upward. In addition to any combination of the features described above, generating the second audio content may include generating the second audio content to provide a height channel when the auxiliary speaker is present.

[0006] In addition to any combination of the features described above, generating second audio content may include generating second audio content to provide a first channel in an audio system. In addition to any combination of the features described above, the method may also include using an electronic processor to generate third audio content to be output by an auxiliary speaker to provide a second channel in the audio system. The auxiliary speaker may include a second speaker having a second main radiation axis relative to the display screen, which is different from the main radiation axis of the speaker of the display device.

[0007] In addition to any combination of the features described above, the method may further include receiving user input via a user input device using an electronic processor. In addition to any combination of the features described above, determining the presence of an auxiliary speaker may be based on user input. In addition to any combination of the features described above, determining that the speaker has been modified relative to the main radiation axis of the display screen to a second direction different from the first direction may be based on user input. In addition to any combination of the features described above, modifying the device data of the display device indicating that the speaker is relative to the main radiation axis of the display screen to indicate that the speaker is in a second direction relative to the main radiation axis of the display screen may be based on user input.

[0008] In addition to any combination of the features described above, the second direction may be defined at least in part by at least one of the following: a waveguide coupled to the display device, an adjustable sound guiding feature on the display device, a sound guiding feature on an auxiliary speaker, the rear surface of the display device, a surface behind the display device facing the rear surface of the display device, and combinations thereof.

[0009] Except for any combination of the features described above, the first direction and the second direction may differ from each other by at least thirty degrees.

[0010] In addition to any combination of the features described above, determining that the speaker has been modified to be in a second direction relative to the main radiation axis of the display screen may include using an electronic processor to determine the second direction based on information received from the auxiliary speaker, the detected position of a manually movable sound guiding feature of the display device housing, or both the information received from the auxiliary speaker and the detected position of a manually movable sound guiding feature of the display device housing.

[0011] In addition to any combination of the features described above, the method may further include using an electronic processor to determine a second direction based on information received from an auxiliary speaker, based on the type of a second audio content, or based on both information received from an auxiliary speaker and the type of a second audio content. In addition to any combination of the features described above, the method may further include, in response to determining the second direction, performing at least one of the following: (i) controlling an actuator to move a sound-guiding feature of the display device housing, and (ii) providing a notification to a user via the display device, wherein the notification may instruct the user to move a manually movable sound-guiding feature of the display device housing.

[0012] In addition to any combination of the features described above, the method may also include coupling a waveguide to a display device. The waveguide may be configured to capture sound emitted by a speaker in a first direction and redirect the sound such that the sound is in a second direction relative to the main radiation axis of the display screen.

[0013] In addition to any combination of the features described above, the speaker may include a first speaker and a second speaker, and the second direction of the main radiation axis of both the first speaker and the second speaker may be the same. In addition to any combination of the features described above, the second direction of the speaker relative to the main radiation axis of the display screen may be upward. In addition to any combination of the features described above, generating the second audio content may include generating the second audio content to provide different height channels using each of the first speaker and the second speaker, or to provide a dedicated height center channel using a combination of the first speaker and the second speaker.

Figure 5 , Figure 6 and Figure 8 Another example of an auxiliary speaker. Detailed Implementation

[0019] Display devices in audio playback systems (e.g., televisions, computer monitors, other displays, etc.) include built-in speakers within their housing. For example, many display devices include speakers at the bottom of the housing that provide sound output with the main radiation axis pointing downwards. As another example, some display devices include two speakers near the bottom of the housing that provide sound output laterally with the main radiation axis pointing in opposite directions (i.e., sound output from each of the two speakers to the left and right sides of the display device). In some instances, the built-in speakers of the display device may only provide stereo reproduction. For example, each of the two built-in speakers may provide a portion of the stereo audio output by the display device.

[0020] Many users of display devices also use separate auxiliary speakers (e.g., soundbars) to provide enhanced audio, rather than relying on the display device's stereo audio output. For example, a typical soundbar includes speakers providing a left front channel, a front center channel, and a right front channel (e.g., three speakers). However, in most cases, because the soundbar is located directly below or in front of the display device, it obstructs the display device's built-in sound system. In other words, because the display device's built-in speakers and the soundbar's speakers are in similar directions (e.g., relative to similar main radiation axes of the display device) and provide audio from similar locations, the audio output from both the display device's built-in speakers and the soundbar's speakers does not provide sound from spatially different audio channels. Therefore, the audio output from both the display device's built-in speakers and the soundbar's speakers does not provide a more immersive listening experience compared to using only the soundbar's speakers. Therefore, when using a soundbar, the display device can disable its built-in speakers.

[0021] Immersive audio reproduction systems benefit from having multiple spatially distinct audio channels radiating in various directions within the listening environment, particularly channels that radiate sound upwards towards the ceiling. This ceiling bounce enhances the immersive listening experience for the user / listener by providing auditory cues from above. Therefore, audio playback systems that include display devices and soundbars present technical challenges because the display device's built-in speakers are not utilized, and the entire system fails to deliver an immersive audio experience.

[0022] To address the aforementioned technical challenges, for audio playback systems that incorporate both a display device and a soundbar (e.g., systems that only provide a display device and soundbar for audio output), the output direction of the display device's built-in speakers can be adjusted / redirected to increase the potential number of different audio channels in the audio playback system. Therefore, some different audio channels in the audio playback system can be handled by the soundbar, while other different audio channels can be reproduced using redirection devices through the display device's built-in speakers. Consequently, the entire system includes a greater number of independent audio channels, providing the user with a more immersive audio experience.

[0023] Figure 1 The illustration depicts a listening environment 100 of an audio playback system without auxiliary speakers (such as a soundbar) according to some example embodiments. Figure 1 As shown, the listening environment 100 (e.g., a room in the home of the user / listener 105) may include a ceiling 110 and walls 115. The display device 120 (e.g., a television, computer monitor, etc.) may be as follows: Figure 1 The display device 120 is mounted to wall 115 as shown. Alternatively, the display device 120 can be located on a bracket, entertainment center 135, table, etc. In some instances, the rear surface of the display device 120 faces the wall 115 and is located near the wall 115. For example, the distance between the wall 115 and the rear surface of the display device 120 can be any distance between approximately two centimeters and approximately fifty centimeters.

[0024] As previously indicated herein, display device 120 may include built-in speakers (e.g., two speakers located near the bottom of the housing of display device 120). In some instances, the built-in speakers may output sound (i.e., audio content) along main radiation axes 125A, 125B extending laterally (i.e., left-right) from display device 120. Alternatively or additionally, the built-in speakers may output sound / audio content along a main radiation axis 130 extending downward from display device 120. In some instances, sound output by the built-in speakers may be reflected / bounced from objects (e.g., entertainment center 135) and / or walls to reach user 105. Although Figure 1The diagram shows both main radiation axes 125A, 125B, and 130, but in most instances, the display device 120 is configured to include built-in speakers that output sound via a single set of main radiation axes 125A, 125B (i.e., laterally) or 130 (i.e., downwardly). However, in some instances, the display device 120 may include two sets of built-in speakers, one set outputting sound along the main radiation axes 125A, 125B extending laterally (i.e., left-right) from the display device 120, and the other set outputting sound along the main radiation axis 130 extending downward from the display device 120.

[0025] In some instances, the audio playback system includes a display device 120 and an audio receiver 140 (i.e., a management device). The audio receiver 140 may be communicatively coupled to the display device 120 and may optionally be communicatively coupled to other speakers and / or devices in the listening environment 100. In some instances, the audio receiver 140 may be communicatively coupled to the display device 120 via a wired connection and / or via a wireless connection. The audio receiver 140 is optional and may not be included in some audio playback systems.

[0026] Figure 2 The illustration depicts a listening environment 100 of an audio playback system with an auxiliary speaker 205 (e.g., a soundbar 205) according to some example embodiments. Figure 2 As shown, listening environment 100 and Figure 1 The listening environment shown is the same as 100. However, in Figure 2 In addition to the display device 120 and the optional audio receiver 140, the audio playback system also includes an auxiliary speaker 205 (e.g., a soundbar 205). Figure 2 As shown, the auxiliary speaker 205 can be located on the top surface of the entertainment center 135. Alternatively, the auxiliary speaker 205 can be mounted to the bottom surface of the housing of the display device 120. The auxiliary speaker 205 may include speakers (e.g., three speakers) providing a left front channel, a front center channel, and a right front channel. Figure 2 As shown, the auxiliary speaker 205 can output sound / audio content along the main radiation axis 210 that extends vertically outward / away from the display screen on the front surface of the display device 120.

[0027] As previously indicated herein and as Figure 2As shown, because the built-in speaker of display device 120 and the speaker of auxiliary speaker 205 provide audio towards user 105 in similar directions and are located in similar positions, the built-in speaker of display device 120 can be disabled when auxiliary speaker 205 is used. For example, audio receiver 140 can be communicatively coupled to both display device 120 and auxiliary speaker 205 via a wired and / or wireless connection. In response to determining that auxiliary speaker 205 is connected to the audio playback system, audio receiver 140 can instruct display device 120 to disable its built-in speaker and provide audio content to auxiliary speaker 205 via audio receiver 140. Alternatively, for an audio playback system that does not include audio receiver 140, display device 120 and auxiliary speaker 205 can be communicatively coupled to each other (e.g., via a wired and / or wireless connection) to control the sound output from each device.

[0028] As previously indicated herein, when auxiliary speaker 205 is present, adjusting / redirecting the output direction of the display device's built-in speaker and using the previously unused built-in speaker of display device 120 to output sound / audio content increases the potential number of different audio channels in the audio playback system. Figure 3A and Figure 3B The diagram illustrates an audio playback system including an auxiliary speaker 205 and a display device 120, the display device having sound redirection features 305, 310 for the built-in speaker of the display device 120. Figure 3A and Figure 3B As shown, sound redirection features 305 and 310 will redirect the main radiation axis of the built-in speaker of display device 120 from a first direction (e.g., in...). Figure 3A The middle is downward or Figure 3B Adjust / redirect to the second direction 315, 320 (e.g., upward) (for lateral directions).

[0029] like Figure 3A and Figure 3B As indicated, when the auxiliary speaker 205 is present, compared to disabling the built-in speaker or not redirecting the built-in speaker, the audio playback system of the display device 120 with its main radiation axes 315, 320 redirected includes a greater number of total independent channels, thus providing the user with a more immersive audio experience. For example, Figure 3A and Figure 3B The left front audio channel, front center audio channel, and right front audio channel are shown, respectively provided by the speakers of auxiliary speaker 205. Additionally, redirected sound from the built-in speakers of display device 120 provides a high left audio channel and a high right audio channel. In some instances, the high left and high right audio channels can be combined into a dedicated high center audio channel.

[0030] Figure 3C and Figure 3D Additional examples of audio playback systems with one or more redirected main radiation axes are provided. Figure 3C Similar to Figure 3A (For example, the same display device 120 with a built-in speaker that emits sound downwards is illustrated). However, in Figure 3C In the middle, sound redirection features 325A and 325B display the main radiation axis of the built-in speaker of the display device 120 from a first direction (e.g., in Figure 3C Adjust / redirect (center down) to the second direction 330A, 330B (e.g., lateral), instead of as Figure 3A As shown, upwards. Figure 3C The redirected radiation axes 330A, 330B of the built-in speakers of the display device 120 provide the left and right audio channels, instead of being provided by... Figure 3A The height audio channel provided by the redirected radiation axis 315 shown. Figure 3D A display device 120 with two sets of built-in speakers is shown. These sets of speakers include a set of downward-firing built-in speakers located at the bottom of the display device 120 and a set of side-firing built-in speakers located approximately midway between the bottom and top of the display device 120. In some instances, the main axis of one or both sets of built-in speakers can be as follows: Figure 3D The sound redirection is shown. For example, sound redirection features 335A and 335B show the main radiation axis of the side-emitting built-in speaker of display device 120 from a first direction (e.g., Figure 3D The sound is adjusted / redirected to a second direction 340A, 340B (e.g., upward) from the side. Additionally, sound redirection features 345A, 345B redirect the main radiation axis of the downward-emitting built-in speaker of the display device 120 from the first direction (e.g., in the side direction). Figure 3D Adjust / redirect to a third direction 350A, 350B (e.g., lateral) (the direction is downward), which may correspond to the first direction. Figure 3D It is shown that, in addition to the three forward audio channels provided by the auxiliary speaker 205, each set of built-in speakers of the display device 120 provides a height left audio channel, a height right audio channel, a left audio channel, and a right audio channel via the redirected radiation axes 340A, 340B and 350A, 350B.

[0031] like Figures 3A to 3DAs indicated by the examples provided herein, the first direction of the main radiation axis of the built-in speaker of display device 120 can be in any of a plurality of different directions. Additionally, the second direction of the redirected radiation axis of the built-in speaker of display device 120 can be in any of a plurality of different directions different from the first direction. Such different directions can be selected by the user or otherwise set (e.g., based on the type of auxiliary speaker 205 coupled to display device 120, based on the type of waveguide attached to display device 120, based on which actuators of display device 120 are actuated to guide sound, etc.), as described herein. Furthermore, for example, Figure 3D Different built-in speakers (or different sets of built-in speakers) on the same display device 120 shown may have different second directions.

[0032] Figures 4A to 4C An example waveguide 400 is illustrated as a sound redirection feature 305, 310 serving as a display device 120 according to some example embodiments. Figure 4A The illustration shows a frontal 3D view of Waveguide 400. Figure 4B The illustration shows a perspective view of waveguide 400, a plane 425 representing the rear surface of display device 120, and a plane 455 along the top surface of waveguide 400. Figure 4C The diagram shows the rear profile view of waveguide 400.

[0033] like Figure 4A and Figure 4B As shown, waveguide 400 may include a horn portion 405 and a junction portion 410. Figures 4A to 4C The example waveguide 400 shown is designed to engage with the downward-emitting built-in speaker of the display device 120 on the bottom of the housing of the display device 120. Therefore, the engagement portion 410 faces upward (e.g., toward the downward-emitting built-in speaker) and includes an engagement plate 415 having a throat 420 to receive sound from the built-in speaker of the display device 120. Figure 4A As shown, the throat 420 can face upwards to receive downward-output sound from the built-in speaker. The size and geometry of the throat 420 can vary in different embodiments (e.g., to avoid narrowband cancellation in the sound output from the waveguide 400). The engagement portion 410 is designed to intersect with the horn portion 405 to form an approximately ninety-degree angle between the engagement portion 410 and the horn portion 405. In other words, the waveguide 400 can be folded around the bottom surface of the display device 120 and adapt to the depth cross-sectional profile of the housing of the display device 120. For example, Figure 4B The diagram shows a plane 425 representing the rear surface of the display device 120.

[0034] In other instances, the bonding plate 415 may face different directions and / or the bonding portion 410 and the speaker portion 405 may be oriented differently relative to each other. For example, the design and configuration of the waveguide 400 may be varied depending on the orientation of the built-in speaker of the display device 120.

[0035] like Figures 4A to 4C As shown, a folding and expanding passage exists from the throat 420, which receives sound from the built-in speaker of the display device 120, to the waveguide outlet 430. The folding passage is defined by the throat 420, the engaging portion 410, and the bottom portion of the horn portion 405. The expanding passage is defined by the horn portion 405. Figures 4A to 4C As shown, the expansion path of waveguide 400 (i.e., the flare of waveguide 400) can be implemented on only one side and can be an arc-shaped portion 435 (e.g., an arc). For example, the front side 440 of the horn portion 405 facing the rear of the display device 120 can be substantially parallel to the rear of the display device 120. The first side 445 of the horn portion 405 can be substantially perpendicular to the front side 440 and can be flat and extend substantially vertically, such as... Figure 4A As shown. On the other hand, the second side of the horn portion 405, opposite to the first side 445, may include an arcuate surface 450 defined by the arcuate portion 435, as shown. Figure 4A and Figure 4B As shown. In some instances, the rear side 460 of the horn portion 405 can extend upward from the joining portion 410 at an angle, such that the depth of the horn portion 405 is narrower near the joining portion 410 and wider at the outlet 430, as shown. Figure 4A and Figure 4B As shown.

[0036] In some instances, the shape of the arcuate portion 435 is determined by the difference between the length 465 of the horn portion 405 of the waveguide 400 and / or the inlet width (e.g., defined by the throat 420 or the intersection of the horn portion 405 and the engagement portion 410) and the outlet width (e.g., defined by the outlet 430). For example, the shape of the arcuate portion 435 can be designed to produce asymmetric radiation across the long axis of the waveguide 400 to minimize sound leakage around the sides of the display device 120, with the aim of creating two differently processed high-frequency channels. In some instances, the target frequency range for the waveguide 400 is 500 Hz to 20 kHz. The length 465 is a determining factor for the pilot frequency of the waveguide 400. Variations of the flare of the waveguide 400 are controlled by the linear expansion of the rounded sidewalls 450 and the total depth from the throat 420 to the outlet / opening 430. In some instances, the number of resonances in waveguide 400 increases with increasing length 465, but the “lead-in” frequency that determines the low-frequency extension of waveguide 400 also decreases with increasing length 465. In instances without junction plate 415, anomalies at approximately 10 kHz (e.g., a sharp drop in frequency response) may be caused by cancellation at the intersection of horn portion 405 and junction portion 410. To mitigate the effects of this anomaly, junction plate 415 may be included to allow experimentation with throat geometry, thereby improving the narrowband cancellation that causes narrowband cancellation in the acoustic output. For example, changing the throat geometry of throat 420 affects the frequency of cancellation. In some instances, multiple junction plates 415 with different throat geometries may be interchanged (e.g., removably attached) to junction portion 410 to provide different acoustic effects as needed.

[0037] In some instances, waveguide 400 may include mounting tabs 470A and 470B configured to allow waveguide 400 to be fastened / secured / mounted to the housing of display device 120. For example, mounting tab 470A protrudes from speaker portion 405 and is configured to receive fasteners to secure speaker portion 405 to the rear side of display device 120. Mounting tab 470B protrudes from engagement portion 410 and is each configured to receive fasteners to secure engagement portion 410 to the bottom side of display device 120. In some instances, waveguide 400 is mounted to display device 120 together with a second waveguide having a mirror design and symmetrically mounted around the centerline of display device 120 near two respective built-in speakers of display device 120. For example, two waveguides 400 may be mounted to the rear side of display device 120 such that the arcuate surfaces 450 of each waveguide 400 facing away from each other on the side facing display device 120. Therefore, the sound / audio content output by the built-in speaker of the display device 120 is not output directly downwards or laterally from the built-in speaker. Instead, the sound / audio content output by the built-in speaker is output as high-channel audio content, which is heard as sound diffracted above the top edge of the display device 120 and / or reflected from the ceiling 110 of the listening environment 100. In other words, the built-in speaker can output sound / audio content through the waveguide 400, such that the sound / audio content output by the built-in speaker has such... Figure 5 The main radiating axis 505 extends upward from the display device 120, as shown. Similarly, as... Figure 5 As shown, the height channel provided by the built-in speaker of the display device 120 can be used in combination with the front channel of the auxiliary speaker 205.

[0038] Figures 4A to 4C The waveguide 400 shown is merely an example, and in other embodiments it may vary in shape, size, orientation, cross-section, expansion, length, depth, etc., to optimize certain aspects of sound radiation using, for example, numerical simulation. For example, depending on the location of the built-in speaker of the display device 120 and the desired modification direction of the sound output from the built-in speaker relative to the main radiation axis of the display screen of the display device 120, the waveguide 400 may include different or additional bends. As another example, the dimensions of the arcuate portion 435 may vary depending on the length 465 or the bend required to output sound at the desired location and in the desired direction to maintain the desired frequency response. As yet another example, the waveguide 400 may include more, fewer, and / or different mounting tabs or methods for mounting the waveguide 400 to the display device 120.

[0039] Although Figures 4A to 4CA waveguide 400 removably coupled to display device 120 is shown, but in other instances, other objects, features, etc. (i.e., other sound redirection features) may also be used alternatively or additionally to allow the built-in speakers of display device 120 to be positioned relative to the main radiation axis of the display screen of display device 120 from the first directions 125A, 125B, 130 (see [reference]). Figure 1 ) is modified to a second direction 505, which is different from the first direction (see Figure 5 ).

[0040] In some instances, the housing of display device 120 may include one or more adjustable sound guiding features that can be moved to block sound or guide or reflect sound in a certain direction. The adjustable sound guiding feature may include a flap or manifold that can be manually moved between (i) an undeployed position and (ii) an deployed position, in which the flap or manifold does not intentionally guide sound from the built-in speakers of display device 120, and in the deployed position, the flap or manifold guides sound from the built-in speakers of display device 120. For example, the adjustable sound guiding feature may be a flap or manifold mounted on a hinge that allows the flap or manifold to move between (i) an undeployed position and (ii) an deployed position, in which the flap or manifold remains flush with the housing of display device 120, and in the deployed position, the flap or manifold protrudes outward from the housing of display device 120 to block sound or guide or reflect sound in a certain direction. As a more specific example, the fins or manifolds may surround the built-in speaker when in the deployed position to reduce the amount of sound emitted along the first directions 125A, 125B, 130. The fins or manifolds may also create a boundary / channel on the rear side / surface of the housing of the display device 120 to guide sound emitted from the built-in speaker upwards above the top edge of the display device 120. In some instances, a combination of the rear surface of the display device 120, nearby wall 115 (e.g., the surface behind the display device 120 facing the rear surface of the display device 120), and optional fins or manifolds on the display device 120 will guide sound emitted by the built-in speaker of the display device 120 upwards along the first directions 125A, 125B, 130. Figure 5 The direction indicated is 505.

[0041] In some instances, display device 120 may include sensors configured to determine the position (e.g., not deployed, deployed, or deployed in a certain manner) of each manually adjustable flap or manifold. In some instances, one or more flaps or manifolds may be automatically deployed by display device 120. For example, each flap or manifold may be coupled to an actuator, such as a servo motor, which may be controlled by display device 120 to control the position of each flap or manifold. In some instances, display device 120 may include sensors configured to determine whether waveguide 400 and / or auxiliary speaker 205 are mounted to the housing of display device 120. For example, the sensor may include a magnetic sensor configured to detect magnetic fasteners or magnetic portions of waveguide 400 and / or each adjustable flap or manifold. As another example, the sensor may include an ambient light sensor that can be blocked from light when waveguide 400 is mounted to display device 120 or when each adjustable flap or manifold is in a certain position.

[0042] In some instances, the auxiliary speaker 205 may be mounted to or near the bottom of the display device 120 and may include sound-guiding features (e.g., integrated waveguides, movable sound-guiding features, etc.) configured to block sound from the built-in speakers of the display device 120 or to guide or reflect sound in a certain direction (e.g., redirect sound from the display device 120). In some instances, the sound-guiding features of the auxiliary speaker 205 may be similar to the sound-guiding features of the display device 120 described above.

[0043] Figure 11A and 11BThe illustration shows two different example auxiliary speakers 205 with built-in sound guiding features according to some example embodiments. In some instances, the auxiliary speaker 205 is mounted flush with the display device 120 such that there is no distance between the display device 120 and the auxiliary speaker 205 (e.g., to create a closed / sealed path for sound to travel from the speaker of the display device 120 to the sound guiding features 1105, 1125 of the auxiliary speaker 205). In some instances, the auxiliary speaker 205 is mounted to the display device 120 such that there is a small distance between the display device 120 and the auxiliary speaker 205 (e.g., less than about one millimeter, two millimeters, five millimeters, etc.). In some instances where there is a small distance between the display device 120 and the auxiliary speaker 205, a sealing strip (e.g., an externally added sealing strip, an adjustable or deployable sealing strip built into the display device 120, etc.) and / or the like can be used to close / seal the small distance between the display device 120 and the auxiliary speaker 205 to improve the sound travel of the sound guiding features 1105, 1125 from the speaker of the display device 120 to the auxiliary speaker 205.

[0044] like Figure 11A As shown in the example, the auxiliary speaker 205 may include a sound-directing feature 1105 to redirect sound from the downward-firing speaker of the display device 120 into a left front channel output and a right front channel output 1115. The sound-directing feature 1105 may include: (i) a sound input area 1110 configured to capture sound from the downward-firing speaker of the display device 120, and (ii) a sound output area 1115 configured to be positioned along the main radiation axis (e.g., on the side of the main radiation axis from which sound is received from the display device 120) Figure 11A (Center downwards) Different principal radiation axes (e.g., in) Figure 11A (Forward) Output sound (e.g., Figure 11A (The sound from the display device 120 is redirected 90 degrees). In addition, the auxiliary speaker 205 includes an upward-firing height speaker 1120 to create a 2.0.2 channel system.

[0045] like Figure 11B As shown in the example, the auxiliary speaker 205 may include a sound-directing feature 1125 to redirect sound from the downward-firing speaker of the display device 120 to a high left channel output and a high right channel output 1135. The sound-directing feature 1125 may include: (i) a sound input area 1130 configured to capture sound from the downward-firing speaker of the display device 120, and (ii) a sound output area 1135 for use along the main radiation axis (e.g., on the side where the sound is received from the display device 120) of the main radiation axis ... Figure 11B(Center downwards) Different principal radiation axes (e.g., in) Figure 11B (middle represents upward and forward) output sound (e.g., Figure 11B (The sound from display device 120 is redirected 145 degrees). Additionally, auxiliary speakers 205 include a left channel speaker, a right channel speaker, and a center channel speaker 1140 to create a 3.0.2 channel system. In some instances, the center channel speaker 1140 may not be present, resulting in a 2.0.2 channel system. In some instances, the sound guiding feature 1125 and the sound output area 1135 are designed to output sound upwards and forwards, making... Figure 11B The auxiliary speaker 205 is located at the bottom of the display device 120, with the sound output area 1135 in front of the display screen 725 of the display device 120. In other examples, the sound guiding feature 1125 and the sound output area 1135 are designed to output sound upwards and backwards, so that... Figure 11B The auxiliary speaker 205 is located at the bottom of the display device 120, wherein the sound output area 1135 is behind the display screen 725 of the display device 120 (e.g., sound can be reflected from the wall behind the display device 120, as explained herein).

[0046] Figure 11A and Figure 11B The auxiliary speaker 205 shown is merely an example. Other variations and / or combinations of sound-directing features on the auxiliary speaker 205 and the built-in speaker may exist in other instances. For example, some display devices 120 include a downward-firing tweeter dedicated to the center channel output in addition to the downward-firing left and right channel outputs. For use with such a display device 120, the auxiliary speaker 205 may include: (i) a center sound-directing feature that redirects the sound from the downward-firing tweeter of the center channel in the display device 120 by ninety degrees to create a forward-firing center channel (e.g., similar to...). Figure 11A (1) Sound steering feature 1105); (2) Left and right sound steering features, which are used to redirect the sound output from the downward-emitting left and right channels of the display device 120 by approximately 145 degrees to create a left height channel and a right height channel (e.g., similar to Figure 11B (1125) sound-directing characteristics); and (3) integrated / built-in left and right front speakers / drivers to create left and right channel outputs. (e.g., similar to Figure 11B (The built-in speaker 1140). When the auxiliary device 205 is present, other variations and combinations can also redirect sound to affect / change the configuration of the sound system.

[0047] In some instances, the housing of the auxiliary speaker 205 may include one or more adjustable sound-guiding features that can be moved to block sound or guide or reflect sound in a direction similar to that described herein with respect to display device 120. Therefore, by adjusting certain components to enable / turn on or disable / turn off certain sound-guiding paths formed by the adjustable sound-guiding features of the auxiliary speaker 205, the same auxiliary speaker 205 can be used with a variety of different types of display devices 120. The description of the adjustable sound-guiding features of display device 120 and any related features / descriptions included herein are similarly applicable to the adjustable sound-guiding features that may be included on the auxiliary speaker 205.

[0048] In some instances, the second direction 505 of the built-in speaker of display device 120 relative to the main radiation axis of the display screen of display device 120 is at least partially defined by at least one of the following: a waveguide 400 coupled to display device 120, an adjustable sound guiding feature on display device 120, a sound guiding feature on auxiliary speaker 205, the rear surface of display device 120, a surface behind display device 120 facing the rear surface of display device 120, and combinations thereof. In some instances, the second direction 505 of the built-in speaker of display device 120 relative to the main radiation axis of the display screen of display device 120 is additionally or alternatively defined by the acoustic interaction between the sound output from the built-in speaker and the sound output from one or more other speakers in the audio playback system (e.g., another built-in speaker of display device 120, auxiliary speaker 205 such as a soundbar, different speakers, etc.).

[0049] Figure 6 The illustration shows a block diagram of a device included in an audio playback system 600 according to some example embodiments. For example, the audio playback system 600 may represent... Figure 2 and Figure 5 The audio playback system shown. Figure 6 As shown, the audio playback system 600 may include a display device 120 and an auxiliary speaker 205. The audio playback system 600 may optionally include an audio receiver 140 (i.e., a management device). Figure 6 As indicated, each of devices 120, 205, and 140 can be configured to communicate bidirectionally with each other. This communication can occur via a wired and / or wireless connection. This communication may include control data and / or instructions sent from one device to another. This communication may additionally or alternatively include audio data configured to be output as sound / audio content by one or more devices. In some embodiments, the audio playback system 600 is in conjunction with... Figure 6The different configurations illustrated in the figure include fewer or more components. For example, in some instances, the audio playback system 600 may include one or more additional auxiliary speakers.

[0050] Figure 7 This is a hardware block diagram of a display device 120 according to some example embodiments. In the illustrated example, the display device 120 includes a first electronic processor 705 (e.g., a microprocessor or other electronic device). The first electronic processor 705 includes input and output interfaces (not shown) and is electrically coupled to a first memory 710, a first network interface 715, a speaker 720, and a display screen 725. In some embodiments, the display device 120 is connected to... Figure 7 The different configurations illustrated herein include fewer or more components. For example, display device 120 may include one or more user input devices, such as one or more buttons or joysticks on the housing, or may include remote control devices. As another example, display device 120 may include one or more sensors and / or one or more actuators associated with a movable flap or manifold, as previously explained herein. As yet another example, first electronic processor 705 may include multiple electronic processors within display device 120 that work together to control various aspects of display device 120. Therefore, in the claims, if the apparatus or system is claimed to include electronic processors or other elements configured in a certain way, then, for example for multiple determinations, the claims or claim elements should be interpreted as referring to one or more electronic processors (or other elements), wherein any one or more electronic processors (or other elements) is configured, as claimed, to perform, for example, some or all of the multiple determinations. In some embodiments, display device 120 performs functions other than those described below.

[0051] The first memory 710 may include read-only memory (ROM), random access memory (RAM), other non-transitory computer-readable media, or combinations thereof. The first electronic processor 705 is configured to receive instructions and data from the first memory 710 and execute those instructions, etc. Specifically, the first electronic processor 705 executes instructions stored in the first memory 710 to implement the methods described herein.

[0052] The first network interface 715 sends and receives data to other devices within the audio playback system 600 (e.g., auxiliary speaker 205, audio receiver 140, etc.) and / or external devices outside the audio playback system 600 (e.g., media server). In some embodiments, the first network interface 715 includes one or more transceivers for wireless communication with other devices within the audio playback system 600. Alternatively or additionally, the first network interface 715 may include a connector or port for receiving wired connections to one or more other devices in the audio playback system 600 and / or external devices, such as a connector for receiving a coaxial cable. The first electronic processor 705 may receive media content (e.g., audio data, video / image data, and / or the like) from external devices (e.g., from a media server that provides video and audio data to the display device 120 for output by the display device 120) via the first network interface 715. The first electronic processor 705 may output the media content received from the external devices via a speaker 720, a display screen 725, or a combination thereof. In some instances, speaker 720 may include multiple built-in speakers (e.g., two built-in speakers) as previously described herein.

[0053] Display screen 725 is configured to display images, videos, text, and / or data to a user. Display screen 725 may be a liquid crystal display (LCD) screen or an organic light-emitting diode (OLED) display screen. In some embodiments, a touch-sensitive input interface may also be incorporated into display screen 725 to allow a user to interact with content provided on display screen 725. In some embodiments, display screen 725 incorporates display technologies developed in the future. In some embodiments, speaker 720 and display screen 725 are referred to as output devices that output media content (e.g., images / videos and audio) and other information to user 105 of display device 120.

[0054] Figure 8 This is a hardware block diagram of an auxiliary speaker 205 according to some example embodiments. In the illustrated example, the auxiliary speaker 205 includes a second electronic processor 805 electrically connected to a second memory 810, a second network interface 815, and a speaker 820. These components are similar to those described above. Figure 7The components of the display device 120 are explained with similar names and function in a similar manner to those described above. For example, the second electronic processor 805 sends and receives data from another device within the audio playback system 600 and / or an external device outside the audio playback system 600 via the second network interface 815. In some instances, the speaker 820 may include multiple speakers 820, for example, three separate speakers that can be used to provide separate audio channels, as described previously herein. The speaker 820 may be configured to output audio content from or associated with the display device 120. In some instances, the auxiliary speaker 205 is used in conjunction with... Figure 8 The different configurations illustrated in the figures include fewer or more components. For example, the auxiliary speaker 205 may additionally include a display, such as a touchscreen, and / or other user input device, to allow user 105 to program the settings of the auxiliary speaker 205. As another example, the second electronic processor 805 may include multiple electronic processors that work together to control various aspects of the auxiliary speaker 205. Therefore, in the claims, if the apparatus or system is claimed to include an electronic processor or other elements configured in a certain way, then, for example for multiple determinations, the claim or claim element should be interpreted as referring to one or more electronic processors (or other elements), wherein any one or more of these electronic processors (or other elements) is configured, for example, to perform some or all of the multiple determinations as claimed. In some instances, the auxiliary speaker 205 performs functions other than those described below.

[0055] Figure 9 This is a hardware block diagram of an audio receiver 140 according to some example embodiments. In the illustrated example, the audio receiver 140 includes a third electronic processor 905 electrically connected to a third memory 910, a third network interface 15, and a display screen 920. These components are similar to those described above. Figure 7 The components of the display device 120 are explained with similar names and function in a similar manner to those described above. For example, the third electronic processor 905 sends and receives data from another device within the audio playback system 600 and / or an external device outside the audio playback system 600 via the third network interface 915. In some instances, the audio receiver 140 is connected to... Figure 9The different configurations illustrated in the figures include fewer or more components. For example, the audio receiver 140 may additionally include user input devices (e.g., dials, knobs, buttons, etc.) to allow the user 105 to program settings of the audio receiver 140 for controlling other devices in the audio playback system 600 (e.g., the volume of the audio output). As another example, the third electronic processor 905 may include multiple electronic processors that work together to control various aspects of the audio receiver 140. Therefore, in the claims, if the apparatus or system is claimed to include an electronic processor or other elements configured in a certain way, then, for example for multiple determinations, the claim or claim element should be interpreted as referring to one or more electronic processors (or other elements), wherein any one or more of these electronic processors (or other elements) is configured, as claimed, to perform, for example, some or all of the multiple determinations. In some instances, the audio receiver 140 performs functions other than those described below.

[0056] Figure 10 A flowchart illustrating a method 1000 for generating audio content according to some example embodiments is shown. Method 1000 is described as being executed by an electronic processor 705 (i.e., one or more electronic processors) of a display device 120. However, it should be understood that the electronic processor executing the method 1000 described herein may include any one or a combination of electronic processors located within a single device (e.g., display device 120, auxiliary speaker 205, and / or audio receiver 140) or distributed among various devices (e.g., display device 120, auxiliary speaker 205, and / or audio receiver 140) and / or systems. Therefore, in the claims, if the apparatus or system is claimed to include an electronic processor or other elements configured in a certain way, then, for example for multiple determinations, the claim or claim element should be interpreted as referring to one or more electronic processors (or other elements), wherein any one or more of these electronic processors (or other elements) is configured, as claimed, to perform, for example, some or all of the multiple determinations. To reiterate, these electronic processors and processes may be limited to a single device or may be distributed among multiple devices. Although in Figure 10 The specific order of processing steps, message reception, and / or message transmission is indicated as an example, but such timing and order of steps, reception, and transmission may be varied where appropriate, without negating the purpose and advantages of the examples detailed throughout the rest of this disclosure.

[0057] At frame 1005, the electronic processor 705 of the display device 120 generates first audio content to be output by the speaker 720 of the display device 120. For example, the speaker 720 may include a pair of built-in speakers 720 of the display device 120 configured to provide stereo audio output when the auxiliary speaker 205 is absent. In some instances, the first audio content is based on the display device 120 indicating that the speaker 720 is in a first direction relative to the main radiation axis of the display screen 725 of the display device 120 (e.g., as shown in the image). Figure 1 The device data (shown in the unmodified orientation 125A, 125B, or 130) is generated. For example, the device data may include a device descriptor indicating the presence of any auxiliary speakers 205 (i.e., connected to the display device 120 and / or audio receiver 140 to provide audio output). In some instances, the display device 120 may receive audio data that may be generated / output in a variety of different ways (i.e., audio content is generated in different ways), depending on the device data indicating system specifications (e.g., the presence of auxiliary speakers 205, the number of auxiliary speakers 205 present, the expected location of one or more auxiliary speakers 205 relative to the display device 120, etc.) for different users who may have different audio systems.

[0058] In some instances, the speaker 720 is oriented downwards or laterally relative to the first direction 125A, 125B, 130 of the main radiation axis of the display screen 725, such as... Figure 1 As shown (e.g., when the sound-guiding feature is absent or not deployed on display device 120). In such instances, generating the first audio content includes generating the first audio content to provide a portion of stereo audio when the auxiliary speaker 205 is absent, such as Figure 1 As shown. In other words, the display device 120 can provide stereo audio output solely by its downward-firing built-in speaker 720 or solely by its side-firing built-in speaker 720. In this case, the device data of the display device 120 can accordingly indicate that the auxiliary speaker 205 is absent, and that stereo audio output is provided by the audio output from the built-in speaker 720. Therefore, based on the device data, the electronic processor 705 can generate first audio content to be output as stereo audio output.

[0059] At block 1010, electronic processor 705 determines the presence of auxiliary speaker 205, which is configured to output audio associated with display device 120 (e.g., audio associated with visual information output by display screen 725 of display device 120). In some instances, determining the presence of auxiliary speaker 205 includes determining that auxiliary speaker 205 is connected (e.g., communicatively coupled) to display device 120 and / or audio receiver 140 to provide audio output associated with display device 120. For example, electronic processor 705 can identify that auxiliary speaker 205 is connected to a port of display device 120 or has been paired with display device 120 by receiving identification information identifying the type and / or function of auxiliary speaker 205. This identification information may additionally or alternatively be received from audio receiver 140. In some instances, determining the presence of auxiliary speaker 205 is based on user input received by electronic processor 705 via user input devices of display device 120 or audio receiver 140. For example, user 105 can use a joystick or remote control device on the housing of display device 120 to select an option on the settings menu displayed on display device 120 that indicates that auxiliary speaker 205 has been connected to display device 120.

[0060] At box 1015, the electronic processor 705 determines, based on the presence of the auxiliary speaker 205, that the speaker (i.e., the built-in speaker 720 of the display device 120) has been modified relative to the main radiation axis of the display screen 725 to be in a second direction different from the first direction. In some instances, the second direction 505 of the speaker 720 relative to the main radiation axis of the display screen 725 is upward, such as... Figure 5As shown. In some instances, the electronic processor 705 determines that the main radiation axis of the speaker 720 relative to the display screen 725 has been modified to a second direction solely based on determining the presence of the auxiliary speaker 205. For example, in response to determining the presence of the auxiliary speaker 205, the electronic processor 705 may be configured to assume that one or more sound redirection features have been installed to or deployed on the display device 120 to modify the main radiation axis of the built-in speaker 720. In other instances, the electronic processor 705 determines that the main radiation axis of the speaker 720 relative to the display screen 725 has been modified to a second direction based on user input received by the electronic processor 705 via a user input device of the display device 120 or the audio receiver 140. For example, the user 105 may use a joystick on the housing of the display device 120 or a remote control device to select an option on a settings menu displayed on the display device 120 that indicates a second direction modified by the user using a sound redirection feature (e.g., waveguide 400, adjustable sound steering feature built into the display device, and / or the like). As previously described herein, in some instances, display device 120 may include one or more sensors configured to detect the deployment of an adjustable sound-guiding feature and / or the installation of waveguide 400 and / or auxiliary speaker 205 to display device 120. In such embodiments, electronic processor 705 may determine, based on the detection of such deployment and / or installation, that the main radiation axis of speaker 720 relative to display screen 725 has been modified to a second direction 505. In some instances, electronic processor 705 may also determine the second direction based on which combination of sensors indicates that the sound-guiding feature has been deployed and / or the waveguide 400 has been installed.

[0061] In some instances, determining that the main radiation axis of speaker 720 relative to display screen 725 has been modified to be in a second direction 505 (at box 1015) involves using electronic processor 705 to determine the second direction based on: (i) information received from auxiliary speaker 205, (ii) the detected position of a manually movable sound-guiding feature of the housing of display device 120, or (iii) both the information received from auxiliary speaker 205 and the detected position of a manually movable sound-guiding feature of the housing of display device 120. For example, auxiliary speaker 205 may (e.g., directly or via audio receiver 140) transmit device information to display device 120 indicating the type of auxiliary speaker 205, the intended position of auxiliary speaker 205 relative to display screen 725 of display device 120, and / or the type of audio channel provided by auxiliary speaker 205. Based on the device information of the auxiliary speaker 205, the electronic processor 705 can be configured to assume a certain second direction, control the actuator to obtain that second direction, as explained below, and / or provide the user with a notification to manually adjust to obtain that second direction, as explained below.

[0062] In some instances, the electronic processor 705 determines the second direction 505 based on information received from the auxiliary speaker 205 and / or based on user input received via a user input device. In response to determining the second direction 505, the electronic processor 705 may control an actuator to move an adjustable / movable sound-guiding feature (e.g., a wing, manifold, etc.) built into the housing of the display device 120 to an extended position to block sound from the built-in speaker from being emitted along the first directions 125A, 125B, 130, or to guide or reflect sound emitted by the built-in speaker to the second direction 505. Alternatively or additionally, in response to determining the second direction 505, the electronic processor 705 may provide a notification to the user 105 via the display device 120, wherein the notification instructs the user 105 to move a manually movable sound-guiding feature of the housing of the display device 120 to an extended position to block sound from the built-in speaker from being emitted along the first directions 125A, 125B, 130, or to guide or reflect sound emitted by the built-in speaker to the second direction 505. In some instances, determining that the speaker 720 (i.e., the built-in speaker 720) relative to the main radiation axis of the display 725 has been modified to be in a second direction 505 different from the first directions 125A, 125B, 130 includes controlling one or more actuators to move one or more adjustable / movable sound guiding features and / or to provide notification to the user 105.

[0063] As indicated by some of the examples above, method 700 may include coupling waveguide 400 (e.g., one or more waveguides 400) to display device 120 (e.g., when auxiliary speaker 205 is communicatively coupled to display device 120). As explained earlier herein, waveguide 400 is configured to capture sound emitted by a speaker (e.g., built-in speaker 720 of display device 120) along a first direction and redirect that sound such that the sound is in a second direction relative to the main radiation axis of display screen 725, different from the first direction.

[0064] At box 1020, in response to determining that the main radiation axis of the speaker 720 relative to the display screen 725 has been modified to be in a second direction, the electronic processor 705 modifies the device data of the display device 120 indicating that the speaker is in a second direction relative to the main radiation axis of the display screen 725. In some instances, modifying the device data of the display device 120 includes modifying the device data (e.g., for creating modified device data) to indicate that the speaker 720 is in a second direction relative to the main radiation axis of the display screen 725 (e.g., Figure 5 The second direction 505 shown. The specific second direction can be determined (e.g., assumed or specifically determined) in any one or more of the ways previously described herein (e.g., based on user input, based on sensing data from sensors, based on the type of auxiliary speaker 205, etc.).

[0065] At box 1025, electronic processor 705 generates second audio content to be output by speaker 720 of display device 120. The second audio content can be generated based on device data of display device 120 indicating that speaker 720 is in a second direction relative to the main radiation axis of display screen 725, different from the first direction (i.e., indicating that the main radiation axis of the built-in speaker 720 of display device 120 has been modified). In some instances, because the main radiation axis of speaker 720 relative to display screen 725 is modified from the first direction to the second direction, the second audio content is generated differently from the first audio content. For example, when auxiliary speaker 205 is not present, the first audio content can be generated to provide a portion of stereo audio content outward or downward from display device 120, as explained above regarding box 1005. On the other hand, when auxiliary speaker 205 is present, the second audio content can be generated to provide height channels, because auxiliary speaker 205 can be configured to provide forward audio channels that would otherwise overlap with the outward or downward stereo audio content. In other words, the electronic processor 705 can generate second audio content (e.g., by decoding different signals and / or by applying an ear / auricle filter associated with the height channel sound output) to the signals to provide the first channel (e.g., the height channel) in the audio system. Additionally, the electronic processor 705 can generate a third audio content to be output by the auxiliary speaker 205 to provide the second channel (e.g., the front channel) in the audio system. Figure 5 As shown, the auxiliary speaker 205 includes a second speaker 820 having a second main radiation axis 210 relative to the display screen 725, which is different from the main radiation axis 505 of the speaker 720 of the display device 120. For another example, see... Figure 11B Therefore, the audio playback system can be modified using sound redirection features and by controlling the audio output differently in the presence of the auxiliary speaker 205, in order to include a greater number of total independent channels, thereby providing a more immersive audio experience for the user 105.

[0066] In some instances, the speaker 720 of the display device 120 includes a first speaker 720 and a second speaker 720 (e.g., two built-in speakers 720). In some instances, the second direction of both the first speaker 720 and the second speaker 720 relative to the main radiation axis of the display screen 725 is the same (e.g., Figure 5(See upward direction 505). In some instances, the electronic processor 705 generates second audio content to provide different height channels using each of the first speaker 720 (e.g., providing the left height channel) and the second speaker 720 (e.g., providing the right height channel). In other instances, the electronic processor 705 generates second audio content to provide a dedicated height center channel using a combination of the first speaker 720 and the second speaker 720.

[0067] In some instances, the first direction of the main radiation axis of the built-in speaker 720 of the display device 120 and the second direction (e.g., a modified direction) of the main radiation axis of the built-in speaker differ from each other by at least approximately thirty degrees. For example, Figure 1 and Figure 5 The illustration shows that the first directions 125A, 125B, and 130 differ from the second direction 505 by approximately 90 degrees and approximately 180 degrees, respectively, in the plane defined by the display screen 725. Other angular differences may exist between the first and second directions in three-dimensional space, either in the same plane or in one or more different planes.

[0068] In some instances, the electronic processor 705 determines the second direction based on (i) information received from the auxiliary speaker 205, (ii) the type of the second audio content, or (iii) both the information received from the auxiliary speaker 205 and the type of the second audio content. For example, in response to determining that device information of the auxiliary speaker 205 indicates that the auxiliary speaker 205 already includes a height channel, the electronic processor 705 may determine that a second direction (e.g., a modified direction of the built-in speaker 720) should be used to provide surround sound or dialogue sound in a certain direction. On the other hand, in response to determining that device information of the auxiliary speaker 205 indicates that the auxiliary speaker 205 does not include a height channel, the electronic processor 705 may determine that the second direction should be upward to provide one or more height channels. As another example, in response to determining that the type of the second audio content is associated with a movie played on the display device 120, the electronic processor 705 may determine that the second direction is upward to provide one or more height channels. On the other hand, in response to determining that the type of the second audio content is associated with music played on display device 120 or news programs played on display device 120, electronic processor 705 can determine that the second direction should be forward to provide center channel dialogue.

[0069] In some instances, in response to determining the second direction as just explained above, the electronic processor 705 may perform at least one of the following: (i) controlling an actuator to move the sound-guiding feature of the housing of the display device 120, and (ii) providing a notification to a user via the display device 120, wherein the notification instructs the user to move the manually movable sound-guiding feature of the housing of the display device 120. Thus, the sound-guiding feature can be deployed and / or mounted to the display device 120 to guide sound from the built-in speaker 720 of the display device 120 to the desired second direction based on information received from the auxiliary speaker 205 and / or based on the type of the second audio content.
