[0001] Cross-reference

[0002] This application claims priority to Russian Patent Application No. 2024134286, filed on November 15, 2024, entitled "Audio-Visual Device and Method of Operating Thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This technology relates to an audiovisual device with an adjustable display and a method of operating the same. Background Technology

[0004] Audiovisual devices with adjustable displays are widely used in various fields, such as entertainment systems, video conferencing, and personal computing. These devices are typically characterized by a display screen that is adjustablely connected to a main body that houses speakers, microphones, and other electronic components. While the adjustability of the display provides flexibility in terms of viewing angle and user comfort, it also presents several challenges related to audio capture and sound reproduction quality.

[0005] One problem associated with known devices involves sound blocking and distortion caused by adjustable displays. Typically, speakers are positioned at the front or side of the device, which can be blocked when the display is tilted or adjusted. This blocking suppresses or blocks sound waves, thus reducing overall audio quality and resulting in a suboptimal listening experience. In some cases, the display's positioning can cause reverberation or echo, further reducing sound clarity.

[0006] Another challenge stems from microphone placement. Microphones are typically positioned to optimize voice capture. However, when the display is moved, it changes the distance and angle of the microphone relative to the user's voice, affecting speech recognition and capture, resulting in poor voice pickup, increased background noise, and / or blurred sound.

[0007] Therefore, people desire an audiovisual device and a method of operating such a device that can overcome at least some of the aforementioned drawbacks. Summary of the Invention

[0040] The application of this disclosure is not limited to the construction details and component arrangements stated in the following description or illustrated in the figures. Other embodiments of the invention are possible and it can be practiced or implemented in various ways. Furthermore, the phrases and terms used herein are for descriptive purposes and should not be considered limiting. The use of “comprising,” “including,” “having,” “containing,” “involving,” and variations thereof herein means to cover items listed herein as well as optional additional items. In the following description, the same numerical references refer to similar elements.

[0041] refer to Figures 1 to 6 This describes a non-limiting embodiment of an audiovisual device 10. The audiovisual device 10 has a body 12 and a display 14 connected to the body 12. In this non-limiting embodiment, the display 14 includes a front surface 16 having a flat screen 18 that serves as a visual interface and displays content to a user. The screen 18 is housed within and surrounded by a frame 20. In an alternative non-limiting embodiment, the frame 20 may be omitted, such that the screen 18 covers the entire front surface 16 of the display.

[0042] The display 14 is adjustablely connected to the body 12, thereby allowing the user to adjust the position of the display 14 relative to the body 12. Figure 3 and 4 As depicted, display 14 is connected to body 12 via hinge 22, allowing the user to pivot upwards and downwards (i.e., about a horizontal axis 21 defined by hinge 22). Thus, the user can adjust the tilt angle 24 of display 14. In this non-limiting embodiment, the tilt angle 24 is defined between a display plane 26 extending parallel to the front surface 16 of display 14 and a body plane 28 extending parallel to the front surface 30 of body 12. In some non-limiting embodiments, the tilt angle 24 may range from about 0° to 90°. It is contemplated that in other non-limiting embodiments, the range of the tilt angle 24 may differ. Display 14 includes a rotation mechanism (not depicted) positioned between display 14 and hinge 22 to allow display 14 to rotate between lateral and longitudinal orientations. In some non-limiting embodiments, the rotation mechanism may include a rotary hinge, ball joint, rotary joint, or any other suitable mechanism. It should be noted that in alternative non-limiting embodiments, the rotation mechanism may be positioned between display 14 and body 12. In another alternative, non-limiting embodiment, the display 14 may be connected to the body 12 via a joint (e.g., a ball joint) that allows both tilting and rotation. It is considered that in some non-limiting embodiments, the display 14 may be configured to have additional degrees of freedom; for example, the display 14 may be able to pivot left and right (i.e., about a vertical axis).

[0043] In some non-limiting embodiments, the display 14 can be manually adjusted by a user. In alternative non-limiting embodiments, the audiovisual device 10 may include a motor operatively connected to the display 14 for automatically adjusting the position of the display 14. In further alternative non-limiting embodiments, the display 14 may be configured for both manual and automatic adjustment.

[0044] In this non-limiting embodiment, the audiovisual device 10 further includes two microphone arrays 32, 34. (See reference...) Figure 5 The first microphone array 32 includes two microphones 38 spaced apart from each other and positioned along the upper edge 36 of the display 14. Measured from center to center, the two microphones 38 are positioned 60 mm apart. In some non-limiting embodiments, the first microphone array 32 may include an additional microphone 38 positioned along the lower edge 40 of the display 14. It is understood that the number of microphones 38 in the first microphone array 32, as well as the positioning and spacing of the microphones 38, are not limited and may vary without departing from the scope of the art.

[0045] refer to Figure 3 and 4 The second microphone array 34 includes two sets of microphones 44 and 46. The first set of microphones 44 is positioned along the lateral edge 42 of the display 14. In this non-limiting embodiment, measured from center to center, the first set includes four microphones 44 evenly spaced at a distance of 27.3 mm. In other non-limiting embodiments, the first set may include additional microphones 44 arranged along opposite lateral edges 42 of the display. The second set of microphones 46 is positioned along the back surface 48 of the display 14. In this non-limiting embodiment, the second set includes two microphones 46 arranged on the upper part of the back surface 48 of the display 14. Measured from center to center, the microphones 46 are positioned 27.3 mm apart. It is understood that the number of microphones 44 and 46, as well as their positioning and spacing, are not limited and may vary without departing from the scope of the invention.

[0046] It should be noted that although two microphone arrays 32 and 34 are described, any number of microphone arrays 32 and 34 may be implemented in alternative, non-limiting embodiments. Furthermore, in other non-limiting embodiments, the positioning of the microphone arrays 32 and 34 may differ.

[0047] like Figure 6As depicted, the main body 12 includes a housing 50 that houses speakers 52 and 54, a processor 56, a sensor 58, and various other electronic components (not individually numbered). In some non-limiting embodiments, the housing 50 may include vents or grilles to allow sound to pass freely from the speakers 52 and 54. Additionally, in some non-limiting embodiments, the housing 50 may be constructed of sound-insulating material to improve audio clarity by minimizing vibration and echo.

[0048] In this non-limiting embodiment, housing 50 accommodates two speakers 52, 54. One speaker 52 is configured to be selectively activated based on the position of display 14 (hereinafter referred to as adjustable speaker 52), which will be described in detail below. The other speaker 54 operates continuously to provide a constant audio output (hereinafter referred to as constant speaker 54). It is understood that in other non-limiting embodiments, the number of adjustable speaker 52 and constant speaker 54 is not limited and may vary.

[0049] As described above, the audiovisual device 10 includes a sensor 58. Specifically, the sensor 58 is a position sensor 58 operatively connected to the display 14 for detecting the position of the display 14. In this non-limiting embodiment, the position sensor 58 is a triaxial accelerometer for measuring acceleration along three vertical axes (X, Y, and Z), thereby allowing it to detect motion and orientation in all three-dimensional planes. It is contemplated that in other non-limiting embodiments, other numbers and types of position sensors for detecting the position of the display 14 may be implemented.

[0050] The processor 56 of the audiovisual device 10 is communicatively connected to at least one of the position sensor 58, microphone arrays 32, 34, and adjustable speaker 52. In this non-limiting embodiment, the processor 56 is configured to receive a signal from the position sensor 58 indicating the position of the display 14. Based on the received signal, the processor 56 selectively enables the adjustable speaker 52 and / or one of the microphone arrays 32, 34, as will be described in detail below. In other non-limiting embodiments, the processor 56 is operatively connected to other electronic components, such as motors configured to adjust the display 14.

[0051] refer to Figure 7 The method 100 for operating the audiovisual device 10 will now be described. In a broad sense, the processor 56 of the audiovisual device 10 is configured to receive the position of the display 14 and adjust the audio input and output to optimize the performance of the audiovisual device 10. It should be noted that method 100 is exemplary and not limiting, and therefore, some steps of method 100 may be rearranged and / or omitted without departing from the scope of this art.

[0052] Method 100 begins by adjusting the position of the display 14 relative to the body 12. In this non-limiting embodiment, this may involve rotating the display 14 between lateral and longitudinal orientations and / or tilting the display 14 between various tilt angles 18. In some non-limiting embodiments, the display 14 may be manually adjusted by a user. In other non-limiting embodiments, the display 14 is operatively connected to a motor for automatic adjustment. Further consideration is that the display 14 can be both manually and automatically adjusted.

[0053] In step 102, method 100 continues with the position of display 14 relative to body 12 detected by position sensor 58. In this non-limiting embodiment, position sensor 58 is a triaxial accelerometer connected to display 14. However, it is contemplated that any number or type of position sensor 58 may be implemented.

[0054] Method 100 continues, and in step 104, processor 56 receives the detected position from position sensor 58. In this non-limiting embodiment, method 100 includes processor 58 receiving a signal indicating the orientation and / or tilt angle 24 of display 14.

[0055] In step 106, method 100 continues with processor 56 configuring the adjustable speaker 52. Specifically, after receiving a signal from position sensor 58, processor 56 determines the orientation and tilt angle 24 of display 14 and adjusts the audio output based on the received signal to ensure optimal performance of audiovisual device 10. In this non-limiting embodiment, the selective configuration of the adjustable speaker 52 is based on both the orientation of display 14 and the tilt angle 24 of display 14. Specifically, after receiving a signal from position sensor 58, processor 56 classifies the signal into one of six position zones and selectively enables the adjustable speaker 52 based on which of the six position zones the signal falls into.

[0056] As described above, the orientation of display 14 includes lateral orientation and longitudinal orientation. The tilt angle 24 of display 14 is divided into three tilt ranges (a first range, a second range, and a third range). For example, in some non-limiting embodiments, the first range includes a tilt angle 24 falling between 0° and 37.5°, the second range includes a tilt angle 24 falling between 37.5° and 52.5°, and the third range includes a tilt angle 24 falling between 52.5° and 90°. Thus, six position areas are defined, i.e., two orientations with three tilt segments. The six position areas are predetermined and calibrated during the manufacture of audiovisual device 10. It should be noted that the number of position areas and how these areas are divided between the tilt angle 24 and the orientation are not limited, and therefore, the number of position areas may be different in other non-limiting embodiments.

[0057] In step 108, method 100 continues with processor 56 activating at least one of the two microphone arrays 32, 34. After receiving a signal from position sensor 58, processor 56 determines the orientation of display 14 and adjusts the audio input based on the received signal to ensure optimal performance of audiovisual device 10. In this non-limiting embodiment, the selective activation of microphone arrays 32, 34 is based on the orientation of display 14. If display 14 is in a lateral orientation (i.e., the angle between the longitudinal axis and the vertical axis of display 14 is greater than 45°), then the first microphone array 32 (comprising microphones 38 positioned along the upper edge 36 of display 14) is selectively activated. If display 14 is in a longitudinal orientation (i.e., the angle between the longitudinal axis and the vertical axis of display 14 is less than 45°), then the second microphone array 34 (comprising two sets of microphones 44, 46 respectively on the lateral edge 46 and the back surface 48) is selectively activated. Thus, microphone arrays 32, 34 can be selected to ensure that sound reception is optimized and not obstructed by the position of display 14. In other non-limiting embodiments, other orientations of the display 14 may selectively enable microphone arrays 32, 34, such as a center orientation (i.e., an orientation falling between the lateral and longitudinal orientations) that may selectively enable both microphone arrays 32, 34.

[0058] Modifications and improvements to the above embodiments of this technology will become apparent to those skilled in the art. The above description is intended to be exemplary and not restrictive. The scope of this technology is therefore intended to be limited only by the appended claims.
