Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

[0032] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0033] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0034] Please see Figures 1 to 8This application provides a display stand device that can be used for displaying, promoting, and providing audio-visual experiences of an acoustic device 40 with active noise cancellation. For example, it allows users to control the acoustic device 40 to perform functions such as audio playback, volume adjustment, audio switching, and active noise cancellation. It can also charge the acoustic device 40 while displaying it. Furthermore, it can display promotional phrases and images related to the acoustic device 40 through interactive screens and decorative components. The display stand device includes a display stand 10, a circuit board assembly, a button assembly, and other functional components as needed, which will be described in detail below.

[0035] Please see Figure 1 The display stand 10 is mainly used to place and display the acoustic device 40 so that users can experience the acoustic device 40. For example, users can pick up and wear the acoustic device 40 from the display stand 10. The acoustic device 40 may include headphones with active noise cancellation, smart glasses, hearing aids, etc. Of course, the display stand 10 may also display other products that work with the acoustic device 40, such as the charging case 60 sold with the headphones.

[0036] For example, please refer to Figure 1 The acoustic device 40 includes an earphone assembly with active noise cancellation function. The earphone assembly includes a first earphone 41 for the left ear and a second earphone 42 for the right ear. Both the first earphone 41 and the second earphone 42 implement active noise cancellation function through devices or circuits such as microphones, noise cancellation circuits and speakers. The microphone is used to collect ambient sound and convert it into a noise signal, the noise cancellation circuit is used to generate a noise cancellation signal to cancel the noise signal according to the noise signal, and the speaker is used to play the noise cancellation signal for noise cancellation.

[0037] Please see Figures 1 to 3 The circuit board assembly is located inside the display stand 10. This assembly can be understood as a collection of related components that enable some or all of the functions of the display device. It supports user operation and experience of the acoustic device 40, and also supports other functions of the display stand (such as supplying power to the acoustic device 40, charging box 60, and other electrical components). The circuit board assembly is connected to the acoustic device 40 displayed on the display stand 10 via a connecting cable 50. Specifically, one end of the connecting cable 50 connects to the circuit board assembly, and the other end connects to the acoustic device 40, thus establishing an information exchange relationship between the circuit board assembly and the acoustic device 40, allowing the circuit board assembly to output signals to the acoustic device 40 via the connecting cable 50.

[0038] For example, please refer to Figure 1 and Figure 3The circuit board assembly includes a main control circuit board 21 and multiple function switches 22 for triggering the acoustic device 40 to perform different functions. One end of the connecting cable 50 is connected to the main control circuit board 21 and the other end is connected to the acoustic device 40. The main control circuit board 21 is configured to output corresponding control commands to the acoustic device 40 according to the signals generated after the different function switches 22 are triggered or turned on or off, thereby controlling the acoustic device 40 to perform functions such as active noise reduction, playing audio (e.g., audio files pre-stored in the circuit board assembly), pausing audio playback, and adjusting volume.

[0039] Please see Figure 1 The button assembly includes multiple interactive buttons that correspond one-to-one with multiple function switches 22, and each interactive button is at least partially exposed on the display stand 10; for example, please refer to Figure 2 and Figure 3 The display stand 10 includes a base 11 and a panel 12 covering the base 11; wherein, a space for accommodating circuit board components is formed between the base 11 and the panel 12, interactive buttons are exposed on the panel 12, and acoustic device 40 is placed and displayed on the panel 12; more specifically, the panel 12 has multiple display areas, and the acoustic device 40 and interactive buttons can be located in different display areas.

[0040] Regarding the interactive buttons, they are primarily used to trigger the corresponding function switch 22 under the action of external force applied by the user, allowing the user to control the acoustic device 40 through the display stand device. For details, please refer to... Figure 1 The multiple interactive buttons include a first button 31 and multiple second buttons 32. The first button 31 works in conjunction with a corresponding function switch 22 to allow the user to control the acoustic device 40 with active noise cancellation function to execute and pause the active noise cancellation function. For example, after the user presses the first button 31 and controls the acoustic device 40 to execute the active noise cancellation function, pressing the first button 31 again will control the acoustic device 40 to pause the active noise cancellation function. By repeating this alternation, the acoustic device 40 can be controlled to switch between the state of executing the active noise cancellation function and pausing the active noise cancellation function.

[0041] The second button 32, in conjunction with the corresponding function switch 22, allows the user to control the acoustic device 40 to perform functions other than active noise cancellation. For example, the plurality of second buttons 32 may include buttons that allow the user to control the acoustic device 40 to perform audio playback and pause audio playback; or, for example, buttons that allow the user to control the acoustic device 40 to perform audio switching; or, for example, buttons that allow the user to control the acoustic device 40 to perform volume adjustment. Of course, as needed, the plurality of second buttons 32 may also include buttons that allow the user to control the booth device to perform its own functions (e.g., on / off).

[0042] On the one hand, when the acoustic device 40 with active noise cancellation is displayed on the display stand 10, based on the cooperation of the first button 31 and its corresponding function switch 22, the user can control the acoustic device 40 to perform active noise cancellation and pause active noise cancellation through the first button 31. By comparing the acoustic effects of the acoustic device 40 before and after active noise cancellation, the user's experience with the active noise cancellation performance is enhanced, thereby effectively improving the user's positive impression of the acoustic device 40. At the same time, based on the cooperation of the second button 32 and its corresponding function switch 22, the user's experience and control needs for the basic functions of the acoustic device 40 can be met. For example, the user can control the acoustic device 40 to perform basic or general functions such as audio playback and pause, audio switching, and volume adjustment by operating different second buttons 32.

[0043] On the other hand, the first button 31 can provide support for expanding the functionality or versatility of the booth device, thereby meeting the needs of the acoustic device 40 for updates and iterations. For example, the acoustic device 40 can be electronic products such as headphones, smart glasses, and hearing aids that do not have active noise cancellation. In this case, multiple second buttons 32 can meet the user's needs for operating and experiencing such acoustic devices 40. In this way, the booth device can be used to display acoustic devices 40 with active noise cancellation or acoustic devices 40 without active noise cancellation, thereby effectively enhancing the versatility of the booth device.

[0044] It should be noted that the descriptions of the acoustic device 40 and the connecting cable 50 in this document are solely for the purpose of understanding the structure, implementation principle, and effect of the exhibition stand device, and do not imply that the acoustic device 40 or the connecting cable 50 is necessarily a component of the exhibition stand device. In other words, in some embodiments, the acoustic device 40 (or together with the connecting cable 50) can be a component of the exhibition stand device. The acoustic device 40 is displayed on the display stand 10 and connected to the circuit board assembly via the connecting cable 50 in a replaceable or non-replaceable manner to form the exhibition stand device, thereby enabling users to experience the acoustic device 40. In other embodiments, the acoustic device 40 (or together with the connecting cable 50) is not a component of the exhibition stand device, but rather an object displayed on the display stand 10 during the application of the exhibition stand device. The acoustic device 40 is connected to the circuit board assembly via the connecting cable 50 in a replaceable or non-replaceable manner, enabling users to experience the acoustic device.

[0045] In some embodiments, please refer to Figure 1The circuit board assembly also includes an auxiliary circuit board, which is mainly used to provide structural support for the function switch 22 and establish a signal connection between the function switch 22 and the main control circuit board 21. Specifically, the auxiliary circuit board includes a first circuit board 23 and a second circuit board 24 that are independent of each other. The first circuit board 23 and the second circuit board 24 are respectively connected to the main control circuit board 21. The first circuit board 23 can be located inside the display stand 10 in a position opposite to the first button 31. The function switch 22 corresponding to the first button 31 is set on the first circuit board 23 and located between the first circuit board 23 and the first button 31. The first button 31 can be connected to the display stand 10 (specifically, the panel 12) or the first circuit board 23. When the first button 31 is moved toward the first circuit board 23 by the external force applied by the user, the corresponding function switch 22 can be triggered, thereby controlling the acoustic device 40 to perform active noise cancellation or pause the active noise cancellation function.

[0046] Based on the same requirement, the second circuit board 24 can be positioned inside the display stand 10 opposite to multiple second buttons 32. The function switch 22 corresponding to the second button 32 is set on the second circuit board 24 and is located between the second circuit board 24 and the corresponding second button 32. The second button 32 can be connected to the display stand 10 (specifically, panel 12) or the second circuit board 24. When the second button 32 is moved toward the second circuit board 24 by the external force applied by the user, the corresponding function switch 22 can be triggered, thereby controlling the acoustic device 40 to perform the corresponding function.

[0047] Thus, by separating the first circuit board 23 (along with the first button 31 and its corresponding function switch 22) and the second circuit board 24 (along with the second button 32 and its corresponding function switch 22) relatively independently, it is beneficial to enhance the flexibility of the structural design and assembly of the booth device and reduce the assembly and application costs of the booth device.

[0048] For example, based on the existing structural system of some exhibition booth devices, by adding a first circuit board 21, a first button 31 and its corresponding function switch 22, the exhibition booth device can not only be made suitable for display, promotion and audio-visual experience of acoustic devices 40 with active noise cancellation function, thereby effectively reducing the design, assembly and application cost of the exhibition booth device, but also facilitate the flexible selection of the setting position of the first button 31 on the display stand 10.

[0049] For example, by making targeted designs for the first button 31 and its related components and the second button 32 and its related components, the flexibility of the booth assembly can be effectively enhanced; or, by connecting the first button 31 and the like to the panel 12, the interactive buttons and the panel 12 can be disassembled and replaced as a functional structure relatively independent of the base 11 and the circuit board assembly.

[0050] It should be noted that, Figure 1 The bold dashed lines in the diagram represent the main control circuit board 21, the first circuit board 23, and the second circuit board 24. However, it is understood that these bold dashed lines only schematically show the approximate location of the corresponding circuit boards inside the display stand 10 and do not represent the structural form, size parameters, etc. of the corresponding circuit boards.

[0051] In some embodiments, the function switch 22 corresponding to the first button 31 and the function switch 22 corresponding to the second button 32 can also share the same auxiliary circuit board. That is, the first circuit board 23 and the second circuit board 24 can be combined into one circuit board, thereby enhancing the integration of multiple function switches 22 and allowing the auxiliary circuit board and function switches to be disassembled and assembled as a relatively independent and complete functional component. In some embodiments, the auxiliary circuit board and the main control circuit board 21 can also be combined into one circuit board, or one of the first circuit board 23 and the second circuit board 24 can be combined with the main control circuit board 21 into one circuit board to meet the structural layout needs of the display stand 10 or the overall display stand device. All these variations will not be elaborated upon here.

[0052] In some embodiments, please refer to Figures 3 to 7 The first button 31 includes a first button body 311 and a first cantilever 312; wherein, the first button body 311 can be disposed through the panel 12 so that the first button body 311 is at least partially exposed on the display stand 10; for ease of distinction and description, the end of the first button body 311 exposed on the display stand 10 is defined as the force-bearing end of the first button body 311, and the end of the first button body 311 inside the display stand 10 is defined as the trigger end of the first button body 311. That is to say, the force-bearing end and the trigger end can be understood as the two opposite ends of the first button body 311 in its length direction.

[0053] Regarding the first cantilever 312, the first cantilever 312 is located inside the display stand 10 (specifically, within the accommodating space). One end of the first cantilever 312 in the length direction is integrally connected to the trigger end of the first key body 311, while the other end of the first cantilever 312 in the length direction is connected to the display stand 10 (specifically, the panel 12).

[0054] Thus, by using the first cantilever 312 to establish a structural connection between the first key body 311 and the display stand 10 from inside the display stand 10, not only can the impact of the first key 31 on the appearance and structure of the display stand 10 be reduced, but the first key body 311 can also be restricted to the display stand 10 in a manner that is approximately suspended or suspended, thereby giving the first key body 311 the ability to move relative to the display stand 10 and the corresponding function switch 22 based on the first cantilever 312. Specifically, when the force-receiving end of the first key body 311 receives an external force applied by the user (e.g., the user presses the first key body 311 through the force-receiving end), the first cantilever 312 can allow the first key body 311 to move toward the corresponding function switch 22; when the external force is removed, the first cantilever 312 can provide a force to the first key body 311 to make it move back to its original position, thereby triggering the corresponding function switch 22 by the trigger end of the first key body 311 during the movement of the first key body 311, so as to control the acoustic device 40 to execute and pause the active noise cancellation function.

[0055] In some embodiments, please refer to Figures 4 to 7 The number of first cantilever arms 312 is set to two; viewed along the movement direction of the first button body 311, each first cantilever arm 312 is an arc segment; and the two arc segment first cantilever arms 312 are rotationally symmetrical about the first button body 311. On the one hand, by arranging the two first cantilever arms 312 rotationally symmetrically about the first button body 311, it is beneficial to enhance the balance of force on the first button 31 and the structural strength, reduce the risk of breakage of the first cantilever arms 312 and the first button body 311, and enable the first button body 311 to move more smoothly relative to the display stand 10 and the corresponding function switch 22, thereby enhancing the tactile feel of the user pressing the first button 31. On the other hand, the arc segment structure of the first cantilever arms 312 is beneficial to reduce the overall size of the first button 31 and allows the first button body 311 to have a larger travel distance under external force, thereby achieving effective triggering of the corresponding function switch 22.

[0056] In some embodiments, please refer to Figure 5 and Figure 6 One of the two first cantilever arms 312 is provided with a foolproof structure 312a. This foolproof structure 312a can be a planar structure formed by partially flattening the outer arc surface of the first cantilever arm 312, or it can be other structures provided on the first cantilever arm 312, such as through holes, protrusions, notches, etc. The foolproof structure 312a can play a foolproof positioning role during the assembly process of the first button 31, so that the assembly personnel can quickly and accurately install the first button 31 onto the display stand 10.

[0057] In some embodiments, please refer to Figure 5 and Figure 6The first cantilever 312 has a cantilever portion 312b and a positioning portion 312c that are integrally connected along its length direction; wherein, the length of the cantilever portion 312b in the length direction is greater than the length of the positioning portion 312c, which can also be understood as the positioning portion 312c being the end of the first cantilever portion 312 away from the first key body 311 in the length direction; and the end of the cantilever portion 312b away from the positioning portion 312c is integrally connected to the trigger end of the first key body 311.

[0058] The positioning part 312c can serve as a carrier for connecting the first button 31 to the display stand 10, while the cantilever part 312b allows the first button body 311 to have a travel relative to the display stand 10 and the corresponding function switch 22 under the action of external force. For example, the positioning part 312c is provided with a positioning hole 312d. Screws and other fasteners pass through the positioning hole 312d through the positioning part 312c, so that the positioning part 312c can be fastened to the display stand 10 (e.g., panel 12), thereby facilitating and quickly assembling the first button 31 onto the display stand 10.

[0059] In some embodiments, please refer to Figure 7 and combined Figure 3 , Figure 5 and Figure 6 On a reference plane perpendicular to the moving direction of the first key body 311, the width D1 of the projection of the cantilever portion 312b can be between 1.58mm and 2.40mm, the length of the projection of the cantilever portion 312b can be within the range of 38mm ± 0.15, the diameter D2 of the projection of the first key body 311 can be within the range of 19.98mm ± 0.10, and the distance D3 between the positioning holes 312d of the two first cantilever 312s can be within the range of 27mm ± 0.08; while in the moving direction of the first key body 311, the thickness of the cantilever portion 312b can be within the range of 1.2mm ± 0.08.

[0060] By limiting the dimensions of the relevant structural parts of the first button 31, it is beneficial to ensure the structural strength of the first button 31 and to give the first button body 311 a larger travel distance, while also helping to improve the user's touch feel when pressing the first button 31.

[0061] In some embodiments, please refer to Figure 3 and Figure 5The first key body 311 includes a key sleeve portion 311a and a key core portion 311b. The key sleeve portion 311a can be disposed through the panel 12 so that one end of the key sleeve portion 311a is exposed on the display stand 10 as the force-receiving end of the first key body 311, and is used to receive the external force applied by the user. The first cantilever 312 (specifically, the end of the cantilever portion 312b away from the positioning portion 312c) is integrally connected to the end of the key sleeve portion 311a inside the display stand 10. One end of the key core portion 311b is inserted into the key sleeve portion 311a so that the other end of the key core portion 311b is used as the trigger end of the first key body 311 to trigger the function switch corresponding to the first button 31. Of course, when the key core 311b is fully inserted into the key sleeve 311a (i.e., the end face of the key sleeve 311a connected to the first cantilever 312 is flush with or extends beyond the end face of the key core 311b), the other end of the key sleeve 311a can also be used as the trigger end of the first key body 311.

[0062] For example, please refer to Figure 5 and Figure 6 The inner wall of the key sleeve portion 311a is provided with a protruding structure 311c, while the side wall of the key core portion 311b is provided with a groove structure (not shown in the figure). During the assembly of the key sleeve portion 311a and the key core portion 311b to form the first key body 311, the protruding structure 311c can be aligned and inserted into the groove structure to guide the key sleeve portion 311a and the key core portion 311b, thereby ultimately restricting or positioning the key core portion 311b within the key sleeve portion 311a. Within 1a; for example, during the assembly and assembly of the first button 31, the key core 311b can first be positioned and inserted into the key sleeve 311a based on the cooperation between the groove structure and the protrusion structure 311a, and then adhesive can be applied around the key core 311b to fix the key core 311b and the key sleeve 311a; finally, the first cantilever 312 can be fixed to the panel 12 using screws and other fasteners, and the first button 31 can be finally assembled on the display stand 10.

[0063] Therefore, by setting the first button 31 as a split assembly structure, the selection of materials for the first button 31 can be more flexible, and the structure of the related molding die is also simpler, which helps to reduce the manufacturing cost of the first button 31. At the same time, the structure of the key sleeve part 311a and the key core part 311b can be adapted according to the structure of the function switch 22 corresponding to the first button 31, so as to enhance the compatibility between the first button 31 and the corresponding function switch 22.

[0064] For example, the first cantilever 312 and the key sleeve 311a can be an integral structure made of plastic material (such as ABS plastic), which is beneficial to enhance the structural strength, pressure resistance and mobility of the first button 31; the key core 311b can be an integral structure made of silicone material, which utilizes the flexibility and high temperature resistance of silicone material to reduce the wear and tear on the function switch 22 and provide support for further expanding the practical functions of the first button 31.

[0065] In some embodiments, please refer to Figure 4 and Figure 6 The end of the key sleeve 311a away from the first cantilever 312 is provided with a hollowed-out graphic 311d, and the end of the key core 311b located inside the key sleeve 311a is provided with a graphic protrusion (not shown in the figure). When the key core 311b is inserted and fixed inside the key sleeve 311a, the graphic protrusion is aligned and inserted into or filled within the hollowed-out graphic 311d. The information embodied by the hollowed-out graphic 311d and the graphic protrusion can indicate that the first button 31 is an active noise cancellation button. This allows the user to quickly identify the first button 31 from the display stand 10, thereby controlling the acoustic device 40 to execute and pause the active noise cancellation function.

[0066] Furthermore, in some embodiments, please refer to Figure 3 The circuit board assembly also includes a first light-emitting element 25 corresponding to the first button 31. For example, the first light-emitting element 25 can be one or more LED beads disposed on the first circuit board 23, and the multiple LED beads can be arranged at intervals around the function switch 22 corresponding to the first button 31. Correspondingly, the key core 311b can be made of a light-transmitting material, such as light-transmitting silicone material. In this way, the light emitted by the first light-emitting element 25 can pass through the key core 311b and shine out of the key sleeve 311a, thereby illuminating the raised graphics and text, so that users can more intuitively identify the first button 31 and its function on the display device, so that users can experience the active noise cancellation function of the acoustic device 40.

[0067] In other embodiments, the first button 31 may also adopt other suitable structures to achieve the purpose of triggering the corresponding function switch 22 when subjected to external force, which will not be elaborated here.

[0068] In some embodiments, please refer to Figure 8 and combined Figure 3 and Figure 4The second button 32 can adopt a similar structural form to the first button 31. For example, the second button 32 includes a button body and two arc-shaped cantilever arms integrally connected to the button body. The two cantilever arms are rotationally symmetrical about the button body. The multiple second buttons 32 are arranged in a straight line side by side, and adjacent two second buttons 32 are connected as one unit by their respective cantilever arms (for example, the cantilever arms of adjacent two second buttons 32 share a positioning part 312c). Thus, the multiple second buttons 32 can be combined to form a button module that is relatively independent of the first button 31, the display stand 10 and other components. For ease of distinction and description, the cantilever arm that connects two adjacent second buttons 32 is defined as the second cantilever arm 33.

[0069] Thus, by placing the second cantilever 33 inside the display stand 10 and connecting it to the display stand 10 (e.g., panel 12), the button module can be confined to the display stand 10. On one hand, the second cantilever 33 allows any one of the multiple second buttons 32 to move relative to the display stand 10 when subjected to an external force applied by the user, thereby triggering the function switch 22 corresponding to that second button 32 and controlling the acoustic device 40 to perform a function other than active noise cancellation. On the other hand, setting the multiple second buttons 32 into an integrated button module helps reduce the assembly difficulty of the display stand device and the number of components in the display stand device.

[0070] It is understood that, in some embodiments, referring to the first button 31, each second button 32 may be configured with related structures or components such as hollow graphics 311d, graphic protrusions, and light-emitting elements, so that users can intuitively and accurately identify the function of the second button 32 on the display stand device, thereby controlling the acoustic device 40 to perform related functions; all of these will not be elaborated here.

[0071] Regarding the relative positional relationship between the first button 31 and the button module on the display stand 10, please refer to some embodiments. Figure 1 The first button 31 can be arranged on one side of the button module along the arrangement direction of the multiple second buttons 32. This arrangement allows the button components of the display device to be concentrated in a certain area of ​​the display stand 10, making it convenient for users to operate and experience the acoustic device 40.

[0072] Of course, based on the structural form of the first button 31 being set independently from the button module, the first button 31 can also be placed in other more prominent areas, which can be selected according to the overall structural layout needs of the booth device.

[0073] As in some of the embodiments described above, the acoustic device 40 may include an earphone assembly with active noise cancellation, the earphone assembly including a first earphone 41 for the left ear and a second earphone 42 for the right ear; see also Figure 1The connecting cable 50 includes a first cable bundle 51, a second cable bundle 52, and a first interface component 53. The display stand 10 also includes a second interface component 26 for connecting circuit board components (e.g., the main control circuit board 21). One end of the first cable bundle 51 is connected to the first earphone 41, and the other end is connected to the first interface component 53. One end of the second cable bundle 52 is connected to the second earphone 42, and the other end is connected to the first interface component 53. The first interface component 53 is detachably connected to the second interface component 26. For example, the first interface component 53 and the second interface component 26 can be a Type-C interface, a USB interface, a magnetic interface, a Lightning interface, etc.

[0074] Thus, by cooperating with the first interface component 53 and the second interface component 26, an information interaction connection can be established between the display stand 10 (specifically the circuit board component) and the headphone component to support the user's operation and experience of various functions of the headphone component. At the same time, the headphone component and the connecting cable 50 can be formed into an independent module that can be replaced relative to the main body of the display stand device, thereby increasing the versatility of the main body of the display stand device and reducing the application cost of the main body of the display stand device.

[0075] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
