[0020] This specification provides a knob assembly with integrated buttons (hereinafter referred to as knob assembly) in some embodiments.

[0021] Figure 1 This is an installation diagram of a knob assembly with integrated buttons according to some embodiments of this specification. Figure 2 This is a schematic diagram of the external structure of the integrated button knob assembly after installation, as shown in some embodiments of this specification.

[0022] In some embodiments, such as Figure 1 and Figure 2As shown, the knob assembly includes a button assembly 3, a knob housing 5, a knob sleeve 4, and an encoder 2. The button assembly 3 is connected to the encoder 2 and is embedded within the knob housing 5. The knob housing 5 is fixedly fitted onto the knob sleeve 4, which is connected to the encoder 2. Applying a rotational force to the knob housing 5 causes it to rotate around its central axis, which in turn causes the knob sleeve 4 to rotate synchronously. The central axes of the button assembly 3, the knob housing 5, and the knob sleeve 4 are collinear. The button assembly 3 includes a first operating surface 33, and the knob housing 5 includes a second operating surface 51. The first operating surface 33 and the second operating surface 51 are coplanar with the outer surface 11 of the mounting panel 1 of the knob assembly. The outer surface 11 of the mounting panel 1 is perpendicular to the central axis of the knob housing 5.

[0023] In some embodiments, such as Figure 1 As shown, the knob assembly is entirely embedded within the external component 10. The external component 10 refers to the external device on which the knob assembly is based. For example, the external component 10 can be a speaker, audio system, home theater system, player, etc. The mounting panel 1 is a panel on the external component 10 used for mounting the knob assembly. In some embodiments, the mounting panel 1 of the external component (e.g., a speaker, etc.) has a mounting groove 12. The knob assembly is entirely embedded within the mounting groove 12.

[0024] Button assembly 3 is used to provide users with the ability to press buttons. Button assembly 3 is triggered when pressed, thereby enabling operations such as powering on / off or switching modes.

[0025] In some embodiments, the button assembly 3 includes a button body 31 and a button base 32. For further details regarding the button base 32, please refer to [link to relevant documentation]. Figure 3 And related descriptions.

[0026] The encoder 2 is used to convert mechanical motion into electrical signals. The encoder 2 can detect the rotation angle of the knob assembly or the pressed state of the button assembly 3 and transmit it to the external control circuit. In some embodiments, the encoder 2 is disposed on a circuit board inside the external assembly 10.

[0027] In some embodiments, the button assembly 3 can be connected to the encoder 2 in various ways. For example, the button assembly 3 can be directly connected to the press detection contact inside the encoder 2, so that when the button assembly 3 is pressed, the encoder 2 can directly detect the press action and output a corresponding electrical signal. Alternatively, the button assembly 3 and the encoder 2 can also be electrically connected. For instance, the switch contact of the button assembly 3 can be connected to the circuit interface of the encoder 2 to transmit electrical signals (e.g., continuity, disconnection, or level change) to the encoder 2.

[0028] The knob housing 5 is for the user to access and rotate, and protects the internal structure of the button assembly. In some embodiments, the knob housing 5 is a ring-shaped structure. The user can adjust the volume by rotating the knob housing 5.

[0029] In some embodiments, a through hole is provided in the central region of the knob housing 5, through which the button assembly 3 passes. In some embodiments, a gap is provided between the knob housing 5 and the button assembly 3. The gap between the knob housing 5 and the button assembly 3 can be set to 0.3-0.5 mm.

[0030] In some embodiments, the knob housing 5 surrounds the central button assembly 3, and the knob housing 5 transmits rotational motion to the encoder 2 through the knob bushing 4.

[0031] In some embodiments, the mounting panel 1 provides a mounting opening for the knob assembly, and the outer surface 11 of the mounting panel 1 is a reference plane for the knob assembly. Other components of the knob assembly are mounted inside the mounting panel 1 or in the mounting slot 12, and the top surfaces of the knob housing 5 and the button assembly 3 remain flush with the outer surface 11 of the mounting panel 1 in the final assembled state.

[0032] The knob sleeve 4 is used to transmit the rotational motion of the knob housing 5 to the encoder 2. For example, the knob sleeve 4 is a rotating shaft structure. The knob sleeve 4 is located inside the knob housing 5 and fits tightly with the knob housing 5 to achieve synchronous rotation. The lower end of the knob sleeve 4 is sleeved on the encoder 2. In some embodiments, the knob sleeve 4 is at least partially sleeved and connected to the knob housing 5.

[0033] In some embodiments, the knob housing 5 can be fixedly fitted onto the knob bushing 4 in various ways. For example, the knob housing 5 can be tightly joined to the outer wall of the knob bushing 4 by an interference fit (press-fit) to achieve synchronous rotation. Alternatively, the inner wall of the knob housing 5 can be designed with protrusions or keyways to engage with grooves or keys on the outer wall of the knob bushing 4, thereby achieving synchronous rotation. In some embodiments, the knob housing 5 and the knob bushing 4 can also be fixed by other methods, such as threaded connection, gluing, riveting, or welding.

[0034] In some embodiments, the knob bushing 4 is connected to the rotor of the encoder 2. The rotation of the knob bushing 4 can drive the rotor of the encoder 2 to rotate synchronously, thereby generating a rotation signal from the encoder 2.

[0035] In some embodiments, the knob sleeve 4 is a hollow cylindrical structure, and the button assembly 3 passes through the inside of the knob sleeve 4.

[0036] The central axis of the knob housing 5 refers to the axis passing through the geometric center of the knob housing 5. The central axis of the button assembly 3 refers to the axis passing through the geometric center of the button assembly 3. The central axis of the knob sleeve 4 refers to the axis passing through the geometric center of the knob sleeve 4. In some embodiments, such as Figure 1 As shown, the central axis of the button assembly 3, the central axis of the knob housing 5, and the central axis of the knob bushing 4 are all collinear with axis DD.

[0037] The first operating surface 33 refers to the surface on the button assembly 3 that the user directly contacts and presses. For example, the first operating surface can be the upper surface of the button assembly 3 (i.e., the exposed surface).

[0038] In some embodiments, the wall surface where the first operating surface 33 of the button assembly 3 is located is made of a rough material, or the wall surface where the first operating surface 33 is located is provided with an anti-slip structure.

[0039] In some embodiments, the rough material can be frosted plastic, brushed metal, or matte ceramic, etc. In some embodiments, the anti-slip structure can include, but is not limited to, grooves, ridges, mesh, or fine particles, etc. The wall surface where the first operating surface 33 is located is formed with a rough material or anti-slip structure through surface treatment, such as sandblasting, etching, laser treatment, or texture molding.

[0040] In some embodiments, by setting the first operating surface 33 of the button assembly 3 to a rough material or setting an anti-slip structure, the friction between the finger and the button is effectively increased, thereby improving the operating feel and the accuracy and reliability of pressing.

[0041] The second operating surface 51 refers to the surface of the knob housing 5 that the user directly contacts and applies rotational force to. For example, the second operating surface 51 can be the upper surface of the knob housing 5 (i.e., the exposed surface).

[0042] In some embodiments, the first operating surface 33 and the second operating surface 51 are on the same plane as the outer surface 11 of the mounting panel 1 of the knob assembly. For example, before installation, by controlling the depth of the mounting groove 12 and the dimensions of the components in the knob assembly (such as the button assembly 3, the knob housing 5, the knob bushing 4, and the encoder 2), the first operating surface 33 and the second operating surface 51 after installation can be made to be on the same plane as the outer surface 11 of the mounting panel 1 of the knob assembly.

[0043] In some embodiments, the angle between the outer surface 11 of the mounting panel 1 and the central axis of the knob housing 5 is maintained at 90° to ensure that the knob assembly can be stably pressed into the interior of the mounting panel 1.

[0044] In some embodiments, the first operating surface 33 and the second operating surface 51 are lower than the outer surface 11 of the mounting panel 1. For example, the first operating surface 33 and the second operating surface 51 may be arc surfaces recessed inwards from the mounting panel 1. For example, the first operating surface 33 and the second operating surface 51 may be located 2 mm, 3 mm, 5 mm, etc. below the outer surface 11 of the mounting panel 1, and there is no limitation herein.

[0045] In some embodiments, by designing the first operating surface 31 of the button assembly 3 and the second operating surface 51 of the knob housing 5 to be lower than the outer surface 11 of the mounting panel 1, a recessed structure is formed, thereby effectively avoiding misoperation caused by accidental touch or scratch, and enhancing the safety and reliability of the knob assembly.

[0046] In some embodiments, users can achieve pressing and rotating functions using a knob with integrated buttons. For example, taking a speaker as an example, the user can apply pressure to the first operating surface 33 of the button assembly 3. The button assembly 3 transmits the pressure to the encoder 2, and the encoder 2 outputs an electrical signal, thereby realizing functions such as turning the speaker on and off. The user can also contact the second operating surface 51 of the knob housing 5 and apply rotational force. The knob housing 5 drives the knob bushing 4 to rotate, thereby driving the rotor of the encoder 2 to rotate. The signal output by the encoder 2 changes, thereby realizing volume adjustment.

[0047] In some embodiments, the knob assembly integrates button functions at the center of the knob to achieve a high degree of integration of the user interface, significantly reducing the number of panel openings and the overall volume, and effectively optimizing the internal space of the product. The outer surface of the knob assembly (such as the first operating surface 33 and the second operating surface 51) is flush with the mounting panel 1, forming a simple and smooth integrated appearance, enhancing aesthetics and a sense of luxury. At the same time, the flush design avoids accidental scratches or misoperation, allowing users to complete rotation adjustment and press confirmation from the same position, enhancing the intuitiveness and efficiency of human-computer interaction.

[0048] Figure 3 This is an exploded view of a knob assembly with integrated buttons as shown in some embodiments of this specification.

[0049] In some embodiments, such as Figure 3 As shown, the button assembly 3 includes a button body 31 and a button base 32. The button body 31 is connected to the button base 32. The button body 31 is embedded in the knob housing 5, and there is a gap between the button body 3 and the knob housing 5. The button base 32 is fixed on the encoder 2.

[0050] The button body 31 is for direct contact operation by the user. The button body 31 is located in the central area of ​​the knob housing 5 (e.g., at the central axis of the knob housing 5).

[0051] In some embodiments, the button body 31 is configured to move only axially (up and down) without rotating with the knob housing 5.

[0052] In some embodiments, such as Figure 3 As shown, the button body 31 includes a first button 311 and a second button 312. The first button 311 and the second button 312 are used to perform different functions. For example, the first button 311 is used to turn the speaker on; the second button 312 is used to turn the speaker off. Alternatively, the first button 311 can be used to turn the speaker off; the second button 312 can be used to turn the speaker on. The first button 311 and the second button 312 can also be configured with other functions as needed.

[0053] In some embodiments, there is a gap between the first button and the second button. In some embodiments, the gap between the first button and the second button is less than 0.6 mm.

[0054] In some embodiments, the button body 31 includes a first operating surface 33. For more information on the first operating surface 33, please refer to... Figure 2 Related explanations.

[0055] The button base 32 is used to support the button body 31 and connect to the encoder 2, and to transmit the pressing force to the encoder 2.

[0056] In some embodiments, the button body 31 and the button base 32 can be connected in various ways. For example, the button body 31 and the button base 32 can be connected by means of clips, screws, or adhesive. Another example is that the button body 31 and the button base 32 can be integrally formed. The button body 31 can also be fitted over the button base 32.

[0057] In some embodiments, the button base 32 and the encoder 2 can be connected in various ways. For example, the button base 32 can be directly fixed to the encoder 2 by screws or clips. Another example is that the button base 32 and the encoder 2 are electrically connected.

[0058] In some embodiments, the button base 32 can also be a tactile button. The button base 32 is provided with a spring and a contact point. When the button body 31 is pressed, the spring on the button base 32 is compressed and makes contact with the contact point, thus completing the circuit. When the button body 31 is released, the spring returns to its original position and separates from the contact point, thus breaking the circuit.

[0059] In some embodiments, there is a gap between the button body 31 and the knob housing 5. In some embodiments, the gap between the button body 31 and the knob housing 5 is 0.3-0.5 mm. For example, the gap between the button body 31 and the knob housing 5 is 0.12 mm, 0.2 mm, 0.5 mm, etc., and is not limited here.

[0060] In some embodiments, by configuring the button assembly 3 as a combination of a button body 31 and a button base 32, and by embedding the button body 31 within the knob housing 5 with a gap, the button assembly 3 can perform pressing operations independently of the knob housing 5. By fixing the button base 32 to the encoder 1, it is ensured that the pressing action can accurately actuate the switch located on the encoder 2, providing clear pressing feedback and enabling functional differentiation, making it convenient for users to perform different operations.

[0061] In some embodiments, such as Figure 3 As shown, both the knob housing 5 and the knob bushing 4 are annular parts. The encoder 2 includes an annular shaft 21. The button body 31 is embedded in the knob housing 5, and the button base 32 is embedded in the annular shaft 21. The annular shaft 21 is rotatably arranged along the central axis of the annular shaft 21, and the knob bushing 4 is fixedly connected to the annular shaft 21.

[0062] In some embodiments, both the knob housing 5 and the knob bushing 4 are annular components, for example, hollow cylindrical structures. The button body 31 can be a cylindrical structure.

[0063] The annular shaft 21 is a rotatable annular component (i.e., a rotating shaft) on the encoder 2. The annular shaft 21 can be made of conductive material and detects the rotation angle by contacting fixed contacts. The annular shaft 21 is a hollow cylindrical structure, and the button base 32 is embedded inside the annular shaft 21. The outer diameter of the button base 32 matches the inner diameter of the annular shaft 21.

[0064] The central axis of the annular shaft 21 refers to the axis passing through the geometric center of the annular shaft 21. In some embodiments, such as Figure 3 As shown, the central axis of the annular shaft 21 is collinear with the axis DD.

[0065] In some embodiments, the knob sleeve 4 and the annular shaft 21 can be fixedly connected in various ways. For example, the knob sleeve 4 can be fitted onto the annular shaft 21 by an interference fit. Alternatively, the knob sleeve 4 can be detachably connected to the annular shaft 21 by means of snaps, screws, magnets, etc.

[0066] Figure 4 This is a schematic diagram of the structure of the knob bushing and the annular shaft body according to some embodiments of this specification.

[0067] In some embodiments, such as Figure 4 As shown, the knob bushing 4 includes a guide 41, and the annular shaft 21 includes a guide mating part 211. The guide 41 and the guide mating part 211 are matched.

[0068] The guide member 41 is used to guide the knob sleeve 4 to engage and fix with the annular shaft 21. In some embodiments, the guide member 41 is disposed at one end of the knob sleeve 4 near the annular shaft 21. In some embodiments, the guide member 41 can be a key bar with a hook or a protruding buckle.

[0069] The guide fitting 211 is used to mate with the guide 41 to connect the knob sleeve 4 and the annular shaft 21. In some embodiments, the guide fitting 211 can be a keyway or recess formed on the outer wall of the annular shaft 21. The guide fitting 211 and the guide 41 are dimensionally matched.

[0070] In some embodiments, by setting the guide 41 and the guide mating part 211 and matching them, the rotational transmission between the knob bushing 4 and the annular shaft 21 can be made more precise and stable, effectively preventing relative wobbling or deflection during rotation, thereby improving the reliability of the knob assembly operation; at the same time, the above-mentioned arrangement makes the knob bushing 4 and the annular shaft 21 easy to disassemble, which is convenient for subsequent maintenance.

[0071] In some embodiments of this specification, the button assembly 3 and the rotating mechanism are highly integrated through the setting of the annular component and the embedding of the button base 32 within the annular shaft 21 of the encoder 2. Simultaneously, the fixed connection between the knob sleeve 4 and the annular shaft 21 ensures that the rotation of the knob housing 5 can stably and reliably drive the encoder 2, effectively supporting and simplifying the internal transmission structure of the knob assembly.

[0072] Figure 5 This is a schematic diagram of the contact part and the transmission part of the knob housing according to some embodiments of this specification.

[0073] In some embodiments, such as Figure 5 As shown, the knob housing 5 includes a contact part 52 and a transmission part 53. A snap-fit ​​part 521 is provided on the contact part 52, and a snap-fit ​​mating part 531 matching the snap-fit ​​part 521 is provided on the transmission part 53. The transmission part 53 is fixedly connected to the knob bushing 4. A reset part 54 is provided between the contact part 52 and the transmission part 53.

[0074] The contact part 52 is used to receive the external force applied by the user.

[0075] In some embodiments, the knob housing 5 is divided into upper and lower parts, with the upper part called the contact part 52 and the lower part called the transmission part 53.

[0076] In some embodiments, the contact portion 52 can rotate freely about the central axis of the contact portion 52 relative to the transmission portion 53.

[0077] In some embodiments, the contact portion 52 includes a second operating surface 51. For more information on the second operating surface 51, please refer to... Figure 2 Related explanations.

[0078] The transmission unit 53 is used to transmit the external force applied by the user to the knob bushing 4.

[0079] The snap-fit ​​member 521 and the snap-fit ​​mating member 531 cooperate to transmit the external force of the contact portion 52 to the transmission portion 53. In some embodiments, the snap-fit ​​member 521 is disposed at the end of the contact portion 52 near the transmission portion 53, and the snap-fit ​​mating member 531 is disposed at the end of the transmission portion 53 away from the contact portion 52.

[0080] In some embodiments, such as Figure 5 As shown, the snap-fit ​​member 521 can be a protrusion on the contact portion 52, and the snap-fit ​​mating member 531 can be a groove on the transmission portion 53 that matches the protrusion. In some embodiments, the snap-fit ​​member 521 can be a groove on the contact portion 52, and the snap-fit ​​mating member 531 can be a protrusion on the transmission portion 53 that matches the protrusion.

[0081] In some embodiments, the snap-fit ​​member 521 and the snap-fit ​​mating member 531 may also be other mutually engaging snap-fit ​​structures. For example, the snap-fit ​​member 521 and the snap-fit ​​mating member 531 may be gears, teeth, snap-fits, keyways, etc., with matching shapes.

[0082] The reset member 54 is used to connect the contact portion 52 and the transmission portion 53, and to drive the contact portion 52 back to its initial position. The reset member 54 can be a spring, rubber rod, elastic strip, or other elastic structure. In some embodiments, one end of the reset member 54 is connected to the contact portion 52, and the other end is connected to the transmission portion 53.

[0083] In some embodiments, in the natural state, the latching member 521 and the latching engagement member 531 are separated, and the reset member 54 is in a relaxed state. When the user touches or accidentally scratches the contact portion 52, the contact portion 52 can rotate freely, but it will not cause the lower transmission part 53 and encoder 2 to rotate. When the user applies pressure to the contact portion 52, the contact portion 52 moves closer to the transmission part 53 until the latching member 521 and the latching engagement member 531 contact and engage. Maintaining the pressure and applying a rotational force to the contact portion 52 can drive the transmission part 53 to rotate, which in turn drives the knob sleeve 4 to rotate. The knob sleeve 4 drives the encoder 2 to rotate synchronously, thereby realizing the volume adjustment function. Releasing the button, under the action of the reset member 54, the latching member 521 and the latching engagement member 531 separate, and the contact portion 52 returns to its initial position.

[0084] In some embodiments, by dividing the knob housing 5 into a contact portion 52 and a transmission portion 53, and providing a snap-fit ​​member 521, a snap-fit ​​engagement member 531, and a reset member 54, the knob can obtain axial pressing feedback and automatic reset capabilities while maintaining its rotation function, thereby improving the interactive experience and further preventing accidental touches.

[0085] In some embodiments, a sealing gasket (not shown) is provided between the knob housing 5 and the mounting panel 1. The sealing gasket is fixed to the outer periphery of the knob housing 5 and covers the gap between the knob housing 5 and the mounting panel 1.

[0086] A gasket is a shim used to isolate the knob from the external environment. In some embodiments, the gasket may be made of low-friction silicone or rubber to minimize its impact on the rotation feel. The gasket may be an O-ring or a ring gasket. The size of the gasket matches the clearance between the knob housing 5 and the mounting panel 1.

[0087] In some embodiments, by providing a sealing gasket, the gap between the mounting panel 1 and the knob housing 5 can be effectively filled, effectively preventing dust and liquid from splashing in.

[0089] In some embodiments, such as Figure 6 and Figure 7 As shown, the knob housing 5 includes an operating part 55 and a light-transmitting part 56. The operating part 55 is sleeved around the light-transmitting part 56, and an indicator light 57 is provided inside the knob housing 5.

[0090] The operating section 55 is the area where the user applies external force. The surface of the operating section 55 can be made of a rough material or have an anti-slip structure.

[0091] The light-transmitting part 56 is the area through which light passes through the knob assembly. The light-transmitting part 56 can be made of light-transmitting materials such as inorganic glass, plexiglass, or polycarbonate.

[0092] In some embodiments, the operating part 55 and the light-transmitting part 56 can be integrally formed or connected by means of bonding, snap-fitting, etc.

[0093] Indicator light 57 is a component that emits light. For example, indicator light 57 may include LED lights, fluorescent lights, etc.

[0094] In some embodiments, the color and state of indicator light 57 can be used to indicate different operating states of the speaker. The color and state of indicator light 57 can be preset as needed. For example, a solid white light indicates normal power-on or normal Wi-Fi connection; a flashing blue light indicates Bluetooth pairing; and a red breathing light indicates that the speaker is in mute mode.

[0095] In some embodiments, when the power button is pressed, indicator light 57 may display a preset effect. The preset effect can be set as needed; for example, the preset effect may be a ring light or other dynamic effects.

[0096] In some embodiments, such as Figure 7 As shown, indicator light 57 is a ring containing multiple LED beads.

[0097] In some embodiments, multiple LEDs are evenly distributed along the axial direction of the LED ring. When the user rotates the knob housing 5, the multiple LEDs of the indicator light 57 illuminate sequentially. The number of illuminated LEDs is related to the rotation angle of the knob housing 5. For example, the indicator light 57 is an LED ring including 12 LEDs, and for every 30° increase in the rotation angle, one more LED is illuminated in the indicator light 57.

[0098] In some embodiments of this specification, by setting the indicator light 57 as a ring of LEDs, the current volume adjustment range can be intuitively displayed by the number of LEDs lit.

[0099] In some embodiments, by setting an operation section 5 and a light-transmitting section 56, and setting an indicator light 57 (e.g., a light ring) inside the light-transmitting section 56, an integrated design of visual indication function and operation function is realized, so that users can clearly understand the working status of the device or the current adjustment level through the light indication of the indicator light 57 (such as color and brightness changes), which significantly enhances the interactivity of the knob.

Therefore, it should be emphasized and noted that references to "an embodiment," "one embodiment," or "an alternative embodiment" in different locations throughout this specification do not necessarily refer to the same embodiment. Moreover, certain features, structures, or characteristics in one or more embodiments of this specification can be appropriately combined.

[0102] Similarly, it should be noted that, in order to simplify the descriptions disclosed herein and thus aid in the understanding of one or more embodiments, the foregoing descriptions of embodiments in this specification sometimes combine multiple features into a single embodiment, drawing, or description thereof. In fact, the embodiments have fewer features than all the features of the single embodiments disclosed above.

[0103] In some embodiments, numbers describing the quantity of components and attributes are used. It should be understood that such numbers used in the description of embodiments are modified in some examples with the terms "approximately," "approximately," or "generally." Unless otherwise stated, "approximately," "approximately," or "generally" indicates that the numbers are allowed to vary by ±20%. Accordingly, in some embodiments, the numerical parameters used in the specification are approximate values, which may be changed depending on the characteristics required by individual embodiments. In some embodiments, numerical parameters should take into account specified significant digits and employ a general method of digit reservation. Although the numerical ranges and parameters used to confirm their breadth of range in some embodiments of this specification are approximate values, in specific embodiments, such values ​​are set as precisely as feasible.

[0104] Finally, it should be understood that the embodiments described in this specification are merely illustrative of the principles of the embodiments described herein. Other variations may also fall within the scope of this specification. Therefore, alternative configurations of the embodiments described herein are intended to be illustrative rather than limiting, and should be considered consistent with the teachings of this specification.
