Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0057] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings).

[0060] The speaker is the terminal of the entire audio system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. In the related art, a volume adjustment knob for controlling the volume of the speaker and function buttons for controlling functions such as the switch and play progress of the speaker are usually provided on the housing of the speaker. The volume adjustment knob and the function buttons are generally arranged at intervals, resulting in a large area of the control panel, an unsightly appearance that is not abrupt, and at the same time occupying a large amount of space on the surface of the speaker, resulting in low space utilization rate on the surface of the speaker.

[0061] Currently, the mainstream requirements for smart speakers are to have both touch functions and mechanical knobs, resulting in relatively strict appearance requirements.

[0062] Based on the above concepts and problems, the present invention proposes a control mechanism 100. It can be understood that the control mechanism 100 is applied to an electronic device, and the electronic device can be a speaker 700 or other smart devices, etc., which is not limited herein.

[0063] Please refer to Figures 1 to 9As shown, in the embodiment of the present invention, the control mechanism 100 includes a housing 1, a main circuit board 2, a touch component 3 and a knob component 4. Among them, the housing 1 is provided with a fixing cavity 11, a partition 12 and a bracket 13. The partition 12 is arranged in the fixing cavity 11 and divides the fixing cavity 11 into a fixing groove 121 and an installation groove 122 which are arranged away from each other. The bracket 13 is arranged in the fixing groove 121, and a calibration member 131 is provided on the periphery of the bracket 13. The main circuit board 2 is arranged in the installation groove 122, and the main circuit board 2 is provided with an electrical connection key 21. The touch component 3 is arranged on the side of the bracket 13 facing away from the bottom wall of the fixing groove 121 and is electrically connected to the main circuit board 2. The knob component 4 is rotatably arranged in the fixing groove 121 and is arranged around the bracket 13 and the touch component 3, so that at least part of the inner wall of the knob component 4 is rotationally abutted against the calibration member 131, and part of the knob component 4 penetrates through the partition 12 and is connected to the electrical connection key 21.

[0064] In this embodiment, the housing 1 is used to install, fix, protect and support components such as the main circuit board 2, the touch component 3 and the knob component 4. That is, the housing 1 provides an installation basis for components such as the main circuit board 2, the touch component 3 and the knob component 4. It can be understood that the housing 1 can be a metal housing, a plastic housing or a housing formed by integrally injecting metal and plastic, and is not limited herein.

[0065] It can be understood that the housing 1 has a fixing cavity 11. Optionally, the housing 1 has a cylindrical structure with openings at both ends. A partition 12 is arranged in the housing 1, that is, the partition 12 is arranged in the fixing cavity 11 of the housing 1 and divides the fixing cavity 11 into a fixing groove 121 and an installation groove 122. In order to facilitate the installation of components such as the main circuit board 2, the touch component 3 and the knob component 4, optionally, the openings of the fixing groove 121 and the installation groove 122 are arranged away from each other.

[0066] It should be noted that the housing 1 and the partition 12 can be separately arranged and connected into one body by a fixed connection or a detachable connection method. Of course, in other embodiments, the housing 1 and the partition 12 can also be arranged as an integrally formed structure, such as being formed into an integral structure by an injection molding method, etc., and are not limited herein. It can be understood that the partition 12 is arranged at an angle with the axial direction of the fixing cavity 11. Optionally, the partition 12 is arranged perpendicular to the axial direction of the fixing cavity 11.

[0067] In this embodiment, by arranging the main circuit board 2 in the installation groove 122 and installing the touch component 3 and the knob component 4 in the fixing groove 121 through the cooperation of the bracket 13, the spatial structure of the housing 1 is reasonably distributed, which can not only avoid mutual interference or interference between multiple components, but also integrate the touch component 3 and the knob component 4 on the housing 1.

[0068] It can be understood that the touch component 3 is arranged on the side of the bracket 13 facing away from the partition 12 and is electrically connected to the main circuit board 2, so that the touch operation function can be realized through the touch component 3. The knob component 4 is rotatably arranged in the fixing groove 121, surrounds the bracket 13 and the touch component 3, and part of the knob component 4 penetrates through the partition 12 and is connected to the electrical connection key 21, so that the mechanical knob operation function of the control mechanism 100 can be realized by rotating the knob component 4.

[0069] In this embodiment, the knob component 4 has a hollow structure, so that the knob component 4 can rotate relative to the housing 1 and the touch component 3, and the hollow structure can be used to avoid the bracket 13 and the touch component 3, so as to ensure that there is no interference problem between the knob component 4 and the touch component 3 in terms of structure. At the same time, in order to ensure the rotation operation of the knob component 4 and avoid problems such as displacement of the knob component 4 during rotation, a calibration part 131 is arranged on the periphery of the bracket 13. In this way, when the knob component 4 is rotatably arranged in the fixing groove 121, at least part of the inner wall of the knob component 4 is rotationally abutted against the calibration part 131, so that the calibration part 131 can be used to perform centering or centering adjustment or calibration on the knob component 4.

[0070] It can be understood that when the knob component 4 rotates relative to the housing 1 and the touch component 3, the calibration part 131 on the periphery of the bracket 13 always abuts against the inner wall of the knob component 4, so as to realize the limit of the knob component 4 during rotation to ensure that the knob component 4 is always in the centered state. In order to improve the aesthetics, in this embodiment, the side of the touch component 3 facing away from the bracket 13 is flush with the end face of the knob component 4, which is convenient for users to operate.

[0071] In this embodiment, the knob component 4 has a hollow cavity for accommodating the touch component 3 and the bracket 13, and the periphery of the touch component 3 is in clearance fit with the inner wall of the hollow cavity of the knob component 4, so as to avoid interference of the touch component 3 on the rotation action of the knob component 4. It can be understood that the main circuit board 2 can be a rigid circuit board structure or a flexible circuit board structure, which is not limited here. The main circuit board 2 can not only supply power to the touch component 3, but also realize functions such as signal reception and feedback for the touch component 3 and the knob component 4.

[0072] The control mechanism 100 of the present invention sets a fixed cavity 11 in the housing 1 and arranges a partition 12 in the fixed cavity 11 to divide the fixed cavity 11 into a fixed slot 121 and a mounting slot 122 arranged away from each other. In this way, the touch component 3 and the knob component 4 can be installed and fixed in the fixed slot 121, and the main circuit board 2 can be installed and fixed in the mounting slot 122, so as to realize the reasonable allocation of the installation space of the housing 1 and avoid mutual influence or interference between components. At the same time, by arranging the bracket 13 in the fixed slot 121, the touch component 3 can be installed, fixed and supported by the bracket 13, and the knob component 4 is rotatably arranged in the fixed slot 121, so that the knob component 4 surrounds the bracket 13 and the touch component 3, and part of the knob component 4 penetrates through the partition 12 and is connected to the electrical connection key 21, thus integrating touch and knob, and reasonably arranging the spatial structure to avoid interference between the knob component 4 and the touch component 3. Further, by providing a calibration member 131 on the periphery of the bracket 13, when the knob component 4 is rotatably arranged in the fixed slot 121, at least part of the inner wall of the knob component 4 is rotationally abutted against the calibration member 131. In this way, the calibration member 131 on the bracket 13 can calibrate the knob component 4 during rotation to ensure that the knob component 4 is always in the centered state, thus effectively ensuring the mechanical rotation operation of the knob component 4 and avoiding contact between the knob component 4 and the touch component 3 during rotation.

[0073] In an embodiment, the knob component 4 includes an outer gear 41, an inner gear 42 and a knob 43. Among them, the outer gear 41 has an inner ring 411, and the outer gear 41 is rotatably arranged in the fixed slot 121 so that the inner ring 411 is rotationally abutted against the calibration member 131. The inner gear 42 is arranged in the inner ring 411 and is located between the partition 12 and the bracket 13. The inner gear 42 is meshed and connected with the outer gear 41, and part of the inner gear 42 penetrates through the partition 12 and is connected to the electrical connection key 21. The knob 43 is rotationally abutted against the housing 1 and is connected to the outer gear 41.

[0074] In this embodiment, as Figures 1 to 8 shown, by setting the knob component 4 as a double-gear structure of the knob 43 cooperating with the outer gear 41 and the inner gear 42, it is ensured that the knob 43 of the knob component 4 moves more smoothly during rotation. At the same time, through the gear transmission method, the mechanical knob operation function can be better experienced without affecting touch. It can be understood that the knob 43 of the knob component 4 is arranged in a ring structure, so that the knob 43 has a hollow cavity, which is convenient for providing an accommodation space for the bracket 13 and the touch component 3. At the same time, the touch component 3 is located at the top, and the knob 43 of the knob component 4 is located at the side, so as to integrate the touch component 3 and the knob component 4 into one body, improving the appearance beauty while avoiding mutual interference between the touch component 3 and the knob component 4.

[0075] It can be understood that the external gear 41 can be selected as an annular structure, that is, the external gear 41 has an inner ring 411. In this way, the inner ring 411 of the external gear 41 can continue to provide an accommodation space for the installation of the bracket 13. At the same time, by using the calibration member 131 on the periphery of the bracket 13 to rotatably abut against the inner ring 411 of the external gear 41, the external gear 41 can be centered and positioned. In this embodiment, by connecting the knob 43 to the external gear 41, and arranging the internal gear 42 inside the inner ring 411, between the partition 12 and the bracket 13, and making part of the internal gear 42 penetrate through the partition 12 to be connected to the electrical connection key 21, the internal gear 42 is meshed and connected with the external gear 41. When the knob 43 is rotated, the knob 43 drives the external gear 41 to rotate. At this time, the external gear 41 drives the internal gear 42 to rotate. In this way, the internal gear 42 can be used to operate the electrical connection key 21, so as to realize the mechanical knob function operation.

[0076] In this embodiment, the double-gear transmission method of the cooperation between the internal gear 42 and the external gear 41 is adopted to better experience the mechanical knob operation function without affecting the touch, and the knob 43 can move more smoothly during the rotation process, improving the user's rotation operation experience.

[0077] Optionally, the internal gear 42 has a disc-shaped structure, and the outer diameter of the internal gear 42 is smaller than the inner diameter of the inner ring 411 of the external gear 41. In this way, when the internal gear 42 is located inside the inner ring 411 of the external gear 41, a space structure is formed between the internal gear 42 and the external gear 41, which is convenient for the installation and fixation of the bracket 13 and the partition 12 of the housing 1. In this embodiment, the internal gear 42 is located on one side of the inner ring 411 of the external gear 41 or is eccentrically arranged, that is, the rotation center of the internal gear 42 and the rotation center of the external gear 41 are spaced and parallel.

[0078] In one embodiment, internal teeth 412 are provided on the inner wall of the inner ring 411, and external teeth 421 are provided on the periphery of the internal gear 42. The external teeth 421 are meshed and connected with the internal teeth 412.

[0079] It can be understood that as Figures 1 to 3 、 Figure 7 and Figure 8 shown, by providing internal teeth 412 on the wall of the inner ring 411 of the external gear 41 and external teeth 421 on the periphery of the internal gear 42, the internal gear 42 is connected to the external gear 41 through the meshing of the external teeth 421 and the internal teeth 412. In this embodiment, the external gear 41 is centered and calibrated by using the calibration member 131 on the periphery of the bracket 13, so as to ensure a good meshing connection state between the external teeth 421 of the internal gear 42 and the internal teeth 412 of the external gear 41, and to ensure that no jamming or hysteresis occurs during the transmission process.

[0080] In one embodiment, one of the knob 43 and the outer gear 41 is provided with a limiting groove 431, and one of them is provided with a limiting protrusion 413, and the limiting protrusion 413 is limited in the limiting groove 431.

[0081] In this embodiment, as Figure 2 and Figure 3 shown, by respectively providing the limiting groove 431 and the limiting protrusion 413 on the knob 43 and the outer gear 41, the limiting protrusion 413 is limited in the limiting groove 431, so that the knob 43 and the outer gear 41 are fixedly connected, ensuring that the outer gear 41 is smoothly driven to rotate when the knob 43 is rotated. It can be understood that the limiting groove 431 is provided on the knob 43 and the limiting protrusion 413 is provided on the outer gear 41; or, the limiting groove 431 is provided on the outer gear 41 and the limiting protrusion 413 is provided on the knob 43; or, the limiting grooves 431 and the limiting protrusions 413 are spaced apart on the outer gear 41, and the limiting protrusions 413 and the limiting grooves 431 are spaced apart on the knob 43, so that the limiting groove 431 of the outer gear 41 corresponds to the limiting protrusion 413 of the knob 43, and the limiting protrusion 413 of the outer gear 41 corresponds to the corresponding limiting groove 431 of the knob 43, which is not limited herein.

[0082] It can be understood that the limiting groove 431 can be an annular groove structure arranged along the circumference of the knob 43. At this time, the limiting protrusion 413 is an annular protrusion structure; or, the limiting protrusion 413 is a plurality of spaced protrusion structures, and the plurality of protrusion structures are all spaced and received in the annular limiting groove 431, which is not limited herein. Of course, in other embodiments, a plurality of limiting grooves 431 and a plurality of limiting protrusions 413 are respectively provided, the plurality of limiting grooves 431 are arranged at intervals along the circumference of the knob 43, and the plurality of limiting grooves 431 and the plurality of limiting protrusions 413 are arranged in one-to-one correspondence, which is not limited herein.

[0083] In one embodiment, the inner gear 42 is provided with a rotating shaft 422, the bracket 13 is provided with a first rotating hole 132, the partition 12 is provided with a second rotating hole 123, one end of the rotating shaft 422 is rotatably connected to the first rotating hole 132, and the other end of the rotating shaft 422 rotatably passes through the second rotating hole 123 and is connected to the electrical connection key 21.
