Description

Technical Field

[0001] This utility model relates to the field of rotary switch technology, and in particular to a rotary switch that can produce sound. Background Technology

[0002] In the current field of electronic products, knobs, as core interactive components for parameter adjustment and function switching, are widely used in audio equipment, automotive center consoles, professional mixing consoles, and home appliances. Their tactile feel and feedback directly impact user satisfaction. Currently, most mainstream electronic product knobs on the market use electronic sound generation for operation feedback. This involves using a built-in buzzer or audio chip to output preset electronic sound effects, such as "tick-tock" or "notification tone," when the knob is turned. While this electronic sound generation solution has advantages such as simple structure, low cost, and ease of integration, and allows for flexible adjustment of sound frequency and volume via software to adapt to different product interaction scenarios, it has significant shortcomings in terms of realistic physical feedback. It cannot simulate the unique "tactile feedback" and "physical feedback" of mechanical structures, making it difficult to meet the needs of professional users or high-end products that demand a refined operating experience. In contrast, a few products that prioritize physical feedback employ mechanically designed knobs that produce sound. These knobs primarily generate sound through mechanical friction or impact, such as the contact between a metal spring and a gear slot, or the collision between a plastic locking point and a limiting protrusion. However, these mechanically designed knobs generally suffer from two major problems: First, the operation feels rough and not smooth. Due to the lack of a buffer structure between the rigid contact parts, the knob is prone to jamming and stiffness when turned, especially after long-term use, as wear and tear further exacerbates the deterioration of the feel. Second, the sound effect is singular and cannot be changed. The sound effect is entirely determined by multiple factors, including the material, shape, and assembly precision of the mechanical structure. Once the product leaves the factory, the pitch, loudness, and rhythm of the sound are fixed and cannot be personalized according to user preferences or different usage scenarios (such as quiet or noisy environments). Changing the sound often requires significant modifications to the entire knob structure, which is costly and greatly limits the product's interactive flexibility and user adaptability. In summary, existing electronic product knobs still have significant technological gaps in terms of balancing sound output and tactile feel, as well as personalization adaptability. There is an urgent need for a new knob design that can both guarantee the smooth feel and realistic physical feedback provided by the mechanical structure, and allow for flexible changes in sound output. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sound-emitting knob.

[0004] To achieve the above objectives, a sound-emitting knob includes a housing and a base fitted inside the housing. The housing and the base are connected by a bearing. A sound-emitting area is provided on the inner circumference of the housing. The sound-emitting area has multiple impact grooves arranged in a circular array. A transition arc surface is provided between adjacent impact grooves. A spring groove is provided on the outer side of the base at a position corresponding to the sound-emitting area. A spring and a sound-emitting element that is connected to the spring and can extend and retract out of the spring groove are provided in the spring groove. The end of the sound-emitting element near the sound-emitting area is provided with an outwardly tapered shape. The base is provided with a limiting post that prevents the sound-emitting element from shifting left or right and is connected to the sound-emitting element.

[0005] The outer shell and the base are connected by a bearing, which ensures the coaxiality of the outer shell and the base shell. The smooth rotation of the bearing provides a silky smooth feel when the product rotates. The outer shell has an undulating structure with impact grooves and transition arc surfaces, which facilitates better extension and retraction of the sound-generating component when the outer shell rotates. This ensures that there is no sense of lag during rotation and facilitates a smooth transition. In addition, the end of the sound-generating component is designed with a tapered shape to better fit the transition arc surface. The design of the limiting post is to ensure that the sound-generating component does not shift to the left or right during extension and retraction, thus improving the smoothness of the outer shell rotation.

[0006] Preferably, the spring groove extends towards the base axis in the length direction, the sound-generating component is provided with a stroke groove, the stroke groove is arranged in the same direction as the spring groove, and the limiting post is arranged in the stroke groove to restrict the sound-generating component from moving back and forth along the stroke in the active direction.

[0007] The orientation of the spring groove can prevent the sound-generating component from being subjected to forces from multiple different directions when the outer shell rotates, which is conducive to the contraction of the sound-generating component. When the sound-generating component pops out, it can directly impact the sound-generating area with a large impact force. The stroke groove is designed to guide the movement of the sound-generating component, and together with the limit post, it drives the precise extension and retraction of the sound-generating component.

[0008] Preferably, the impact groove is an arc-shaped groove, and the end of the sound-generating element near the sound-generating area is provided with an impact arc surface corresponding to the impact groove.

[0009] The curved design makes it less prone to damage when the sound-generating component collides with the impact groove, and also facilitates the sound-generating component to detach from the impact groove, ensuring a smooth feel when the outer shell rotates.

[0010] Preferably, the base is interference-fitted with the inner circumference of the bearing, and the outer shell is interference-fitted with the outer circumference of the bearing.

[0011] Preferably, the base is provided with a support platform for supporting the bottom of the bearing, and the base is provided with a fixing member for fixing the upper end of the bearing.

[0012] The design of the support platform and fixing components is to fix the lower and upper ends of the bearing, thereby fixing the bearing position.

[0013] Preferably, the base and the fixing member are connected and fixed by screws, the base is provided with multiple positioning posts, and the fixing member is provided with multiple positioning grooves that correspond one-to-one with the positioning posts.

[0014] To facilitate the installation of the fasteners, the base and the fasteners are fixed together with screws. To ensure the accurate alignment of the screws, positioning posts and positioning slots are used to position and install the fasteners.

[0015] Preferably, the base has a hollowed-out center, and the inner center of the outer shell has a mounting groove corresponding to the buttons of the electronic product.

[0016] Preferably, the outer periphery of the outer casing is provided with anti-slip texture.

[0017] Preferably, the sound-generating element is made of any material that can produce sound upon impact.

[0018] Preferably, the sound-generating component is made of plastic, aluminum alloy, or zinc-magnesium alloy.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This utility model connects the outer shell and the base via a bearing. The bearing ensures coaxiality between the outer shell and the base, and its smooth rotation provides a silky-smooth feel to the product. The outer shell features an impact groove and a transition arc surface, creating an undulating structure that facilitates better extension and retraction of the sound-generating component during rotation, ensuring a smooth transition without any lag. The end of the sound-generating component also incorporates a tapered design to better fit the transition arc surface, while the limiting post design prevents lateral deviation during extension and retraction, further enhancing the smoothness of the outer shell's rotation. Different impact sounds can be produced by using sound-generating components made of different materials. Therefore, users can simply replace the sound-generating component according to their desired impact sound, saving costs and offering a wide range of choices. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] This utility model provides a sound-emitting knob, such as Figures 1-7 As shown, the device includes a housing 1 and a base 2 fitted inside the housing 1. The housing 1 and the base 2 are connected by a bearing 3. The base 2 and the bearing 3 are interference-fitted on their inner and outer circumferences, allowing the housing 1 to rotate smoothly on the base 2. A sound-emitting area 11 is provided on the inner circumference of the housing 1, surrounding the inner circumference of the housing 1. The sound-emitting area 11 has multiple impact grooves 12 arranged in a circular array, with transition arc surfaces 13 provided between adjacent impact grooves 12. A spring groove 21 is provided on the outer side of the base 2 at a position corresponding to the sound-emitting area 11. A spring 22 and a sound-emitting element 23 that is connected to the spring 22 and can extend and retract out of the spring groove 21 are provided in the spring groove 21. When the sound-emitting component 23 contacts the transition arc surface 13, it retracts into the spring groove 21. As the outer shell 1 continues to rotate, the sound-emitting component 23 is misaligned with the transition arc surface 13 and falls into the impact groove 12. The height difference between the transition arc surface 13 and the impact groove 12, along with the return of the spring 22, causes the sound-emitting component 23 to pop out and impact the impact groove 13 of the sound-emitting area 11, thereby producing sound. To ensure a smooth connection between the sound-emitting component 23 and the impact groove 13, the end of the sound-emitting component 23 near the sound-emitting area 11 is provided with an outwardly tapered section. To ensure that the extension and retraction direction of the sound-emitting component 23 is accurate and does not deviate, the base 2 is provided with a limiting post 24 to prevent the sound-emitting component 23 from shifting left or right and is connected to the sound-emitting component 23. The transition arc surface 13 is provided to better guide the extension and retraction of the sound-emitting component 23 when the outer shell 1 rotates, ensuring smooth rotation.

[0030] The rotation of the outer casing 1 drives the sound-generating element 23 to extend and retract, colliding with the impact groove 13 to produce sound. Considering that the retraction of the sound-generating element 23 should minimize the force it experiences from multiple directions, and that the direct collision of the sound-generating element 23 with the impact groove 13 when it extends can make the sound crisper, the spring groove 21 is configured to extend towards the axis of the base 2 in the length direction. The sound-generating element 23 needs to be guided during extension and retraction to ensure the accuracy of its movement. The sound-generating element 23 is provided with a stroke groove 25, which is arranged in the same direction as the spring groove 21. The limiting post 24 is arranged in the stroke groove 25 to restrict the sound-generating element 23 from moving back and forth along the stroke in the active direction.

[0031] The impact groove 13 is an arc-shaped groove. The end of the sound-generating element 23 near the sound-generating area 11 is provided with an impact arc surface 26 corresponding to the impact groove 13. The arc surface design makes the sound-generating element 23 have sufficient contact surface when it is impacted and is not easily damaged. It also facilitates the outer shell 1 to detach from the impact groove 13 when it rotates.

[0032] The base 2 is provided with a support platform 27 for supporting the bottom of the bearing 3. When the bearing 3 is installed, the support platform 27 is used to position the lower end of the bearing 3. The base 2 is provided with a fixing member 4 for fixing the upper end of the bearing 3. The function of the fixing member 4 is to limit the upper end of the bearing 3, thereby ensuring the installation accuracy of the bearing 3.

[0033] The base 2 and the fixing member 4 are connected and fixed by screws 5, which makes the installation convenient. To ensure the accurate alignment of the fixing member 4 and the base 2, the base 2 is provided with multiple positioning posts 28, and the fixing member 4 is provided with multiple positioning slots 41 that correspond one-to-one with the positioning posts 28. The positioning posts 28 and the positioning slots 41 are matched to achieve convenient positioning.

[0034] The base 2 has a hollowed-out section in the middle, and the inner center of the outer shell 1 has a mounting groove 14 corresponding to the electronic product button. The electronic product button can pass through the hollowed-out section and connect with the mounting groove 14.

[0035] The outer periphery of the outer shell 1 is provided with anti-slip texture 15.

[0036] The sound-generating component 23 is made of any material that can produce sound upon impact, and different sounds can be produced by replacing different sound-generating components.

[0037] The sound-generating component 23 is made of plastic, aluminum alloy, or zinc-magnesium alloy.

[0038] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
