[0041] like Figure 1-11 As shown, an embodiment of this utility model provides a gesture-sensing rotary switch, including a middle frame body 1, a knob ring 2, a sensing control component 3, and a contact 4. A first mounting base 5 is provided on the middle frame body 1, and a knob hole 6 is formed on the first mounting base 5. A bracket body 7 is mounted on the first mounting base 5, with its upper part inserted into the knob hole 6. A knob bearing 8 is mounted on the bracket body 7 and is electrically conductive. The knob ring 2 is rotatably fitted onto the knob bearing 8, with its surface exposed in the knob hole 6. The knob ring 2 is electrically conductive, and the knob ring 2 and the knob bearing 8 are electrically connected. The sensing control component 3 includes a circuit board 9. The touch panel 10 and the sensing control component 3 are securely connected to the bracket 7. A sensing chip (not shown) and a button backlight 11 are integrated on the circuit board 9. The touch panel 10 is located inside the knob ring 2. One end of the contact 4 is electrically connected to the circuit board 9, and the other end of the contact 4 abuts against the knob bearing 8. The contact 4 is conductive. The circuit board 9 provides induced current, which is conducted through the contact 4 and the knob bearing 8 to the knob ring 2, forming an induced magnetic field on the knob ring 2. When a hand approaches the knob ring 2, the induced magnetic field changes. The sensing chip senses the change in the induced magnetic field and illuminates the button backlight 11, which then illuminates the touch panel 10. The gesture-sensing rotary switch, by conducting the induced current to the conductive knob ring 2, forms a 360-degree circular induced magnetic field on the knob ring 2, increasing the sensing area and improving the sensing activation rate. It also eliminates the need for additional sensing components, effectively reducing product costs and providing better market competitiveness.

[0042] Specifically, in this embodiment, the main function of the gesture-sensing rotary switch is to turn on the light after sensing a gesture, wherein, for example... Figure 4 As shown, the middle frame body 1 is a shell structure, and an internal space is formed within the middle frame body 1 for mounting components. The middle frame body 1 serves as the main support for other components. More specifically, the middle frame body 1 is rectangular, and a first mounting base 5 is formed on the inner side of the upper end face of the middle frame body. A knob hole 6 is formed on the first mounting base 5, penetrating the front of the middle frame body 1. The first mounting base 5 is adapted to be fastened to the bracket body 7, and the upper part of the bracket body 7 is engaged with the knob hole 6. The bracket body 7 is fastened to the first mounting base 5 with screws, such as... Figure 5 As shown, the bracket body 7 has a cover plate structure, which is suitable for installing and sealing the knob hole 6 inside the knob hole 6. The bracket body 7 also serves as a support for other components, supporting the installation of the knob ring 2 and the sensor control component 3. The bracket body 7 can be integrally molded from plastic material, resulting in lower manufacturing costs and helping to reduce product production costs. The bracket body 7 is securely mounted on the middle frame body 1. The knob bearing 8 is installed inside the bracket body 7. The knob bearing 8 is used to realize the rotation of the knob ring 2 on the middle frame body 1. The knob ring 2 usually serves as the volume control switch of the speaker. Rotation can adjust the volume of the speaker to meet the speaker's setting requirements.

[0043] Furthermore, in this embodiment, as Figure 10 As shown, the knob ring 2 is made of conductive metal material so that the gesture-sensing rotary switch can form a sensing magnetic field on the metal knob ring 2. Preferably, the knob ring 2 is made of stainless steel to improve the appearance quality of the gesture-sensing rotary switch. The knob ring 2 is rotatably mounted on the middle frame body 1 with a knob bearing 8, and the outer surface of the knob ring 2 is exposed through the knob hole 6 to facilitate user operation of the knob ring 2 for volume adjustment. The knob bearing 8 is a conductive metal bearing, so that current can be conducted when the knob ring 2 is fitted onto the knob bearing 8, thereby forming a sensing magnetic field on the knob ring 2. In this embodiment, the sensing control component 3 includes a circuit board 9 and a touch panel 10. The touch panel 10 abuts against the circuit board 9, and the circuit board 9 is a control circuit board. The sensing control component 3 is securely mounted on the bracket body 7. Figure 8-9As shown, the circuit board 9 integrates a sensor chip and button backlights 11. The touch panel 10 is an IML panel, and operation keys 12 are printed on the touch panel 10 using a concealed silkscreen method. The button backlights 11 are arranged at the positions of the operation keys 12. The number of operation keys 12 can be designed as needed to control various modes. By touching the operation keys 12 on the touch panel 10, the circuit board 9 can be activated to control the speaker to perform the corresponding operation. Preferably, in this embodiment, the touch panel 10 is silkscreened with a forward key, a pause / play key, and a rewind key. The three operation keys 12 are arranged in a horizontal straight line. Correspondingly, at least three button backlights 11 are integrated on the circuit board 9. When the three button backlights 11 are lit, the user can more clearly see the accurate position of the operation keys 12, making it easier for the user to perform touch operations. When the user touches the forward key on the touch panel 10, the circuit board 9 controls the speaker to perform fast forward playback or play the next track.

[0044] Furthermore, in this embodiment, the sensing chip is used to sense changes in the magnetic field on the knob ring 2. When the sensing chip detects a change in the magnetic field on the knob ring 2, the circuit board 9 controls the button backlight 11 to illuminate. Specifically, as shown... Figure 1 and Figure 3As shown, a contact 4 is disposed on the circuit board 9. The contact 4 is conductive, with one end electrically connected to the circuit board 9 and the other end abutting against the end face of the knob bearing 8. The knob bearing 8 is then electrically connected to the knob ring 2, so that the induced current on the circuit board 9 can be conducted to the knob ring 2 through the contact 4 and the knob bearing 8 to form an induced magnetic field. More specifically, in this embodiment, the contact 4 is a conductive terminal. Preferably, the contact 4 is a spring pin 13, with one end of the spring pin 13 being an elastic end that compressibly contacts the end face of the knob bearing 8, ensuring good contact between the spring pin 13 and the knob bearing 8. To prevent the spring pin 13 from failing, two or more spring pins 13 are soldered on the circuit board 9, with both spring pins 13 abutting against the knob bearing 8. Thus, when one spring pin 13 fails, the other spring pins 13 can still ensure electrical continuity between the circuit board 9 and the knob bearing 8. Preferably, in this embodiment, there are two spring pins 13. This ensures electrical connection between the circuit board 9 and the knob bearing 8 while controlling production costs. In this embodiment, the circuit board 9 provides induced current, which is conducted to the knob ring 2 via the spring pins 13 and the knob bearing 8. A 360-degree induced magnetic field is formed on the knob ring 2, increasing the sensing area. When a hand approaches the knob ring 2, the induced magnetic field changes. The sensing chip detects this change and illuminates the button backlight 11, which then illuminates the touch panel 10, facilitating the user's touch operation keys 12. By forming a large-area induced magnetic field on the knob ring 2, the user's hand can be activated as long as it is near the main frame 1, regardless of the direction from which the user's hand approaches the gesture-sensing knob switch, thus illuminating the button backlight 11 and improving the activation rate. Furthermore, there is no need to add or set up other sensing components, effectively reducing product costs and enhancing market competitiveness.

[0045] Furthermore, in this embodiment, the knob bearing 8 is equipped with an upper pressure cover 14 and a lower pressure cover 15. The upper pressure cover 14 is fastened to the bracket body 7, and the upper pressure cover 14 and the lower pressure cover 15 press the knob bearing 8 together for installation. Specifically, as shown... Figure 3 , Figure 6 and Figure 7As shown, to securely install the knob bearing 8 and allow the knob ring 2 to rotate smoothly, the knob bearing 8 is secured with an upper pressure cover 14 and a lower pressure cover 15. The upper pressure cover 14 is a plate structure, and the lower pressure cover 15 is an L-shaped cover structure. The upper pressure cover 14 and the lower pressure cover 15 press the knob bearing 8 together for installation. More specifically, a stepped groove 16 is provided on the bracket body 7. The inner ring of the knob bearing 8 abuts against the stepped groove 16. The upper pressure cover 14 presses the inner ring of the knob bearing 8 and is fastened to the bracket body 7 with screws, thereby pressing the knob bearing 8 so that the knob bearing 8 can be securely installed on the bracket body 7, while the outer ring of the knob bearing 8 can rotate. Preferably, a first countersunk hole 17 is provided on the bracket body 7, and a first mounting post 18 is provided on the upper pressure cover 14. The lower end of the first mounting post 18 is embedded in the first countersunk hole 17 for positioning and installation, and screws pass through the first mounting post 18 to fasten the first countersunk hole 17. Preferably, the outer side of the lower pressure cover 15 is formed as an outer ring portion 19, and the inner side of the bottom end of the lower pressure cover 15 is formed as an inner ring portion 20. The outer ring portion 19 is provided with a plurality of fourth through holes 21 evenly arranged in a circle. The lower end face of the knob ring 2 is provided with a plurality of first screw holes 22 corresponding to the fourth through holes 21. The inner ring portion 20 of the lower pressure cover 15 is supported by the lower end face of the outer ring of the knob bearing 8. The outer ring portion 19 of the lower pressure cover 15 is fitted onto the outer ring of the knob bearing 8. The screw passes through the fourth through holes 21 and is fastened to the first screw holes 22, so that the knob ring 2 is fastened to the lower pressure cover 15. With the cooperation of the outer ring of the knob bearing 8, the knob ring 2 can rotate on the middle frame body 1 and cannot come off the middle frame body 1. Preferably, in this embodiment, in order to facilitate the assembly of the knob ring 2 and the lower pressure cover 15, a first positioning protrusion 23 is provided on the upper end surface of the lower pressure cover 15, and a first positioning groove 24 is correspondingly provided on the lower end surface of the knob ring 2. The first positioning protrusion 23 is embedded in the first positioning groove 24 for positioning and installation, so that the lower pressure cover 15 and the knob ring 2 can be accurately matched, making it easy for the fourth through hole 21 to be aligned with the first screw hole 22, and facilitating the fastening installation of the knob ring 2 and the lower pressure cover 15.

[0046] Furthermore, in this embodiment, the knob bearing 8 is also equipped with an isolation sleeve 25, which is fitted onto the knob bearing 8 and isolates the knob bearing 8 from the support body 7. Specifically, as shown... Figure 3As shown, to achieve soft contact between the bracket body 7 and the knob bearing 8, an isolation sleeve 25 is fitted onto the knob bearing 8. The isolation sleeve 25 fits snugly against the bracket body 7, and the upper pressure cap 14 presses down on the upper end of the isolation sleeve 25. The isolation sleeve 25 isolates the knob bearing 8 from the bracket body 7, allowing the small vibrations generated when the knob bearing 8 rotates to be filtered out by the isolation sleeve 25, eliminating rotational noise. Preferably, in this embodiment, the isolation sleeve 25 is a silicone sleeve. Silicone sleeves have good elasticity and low manufacturing cost, which helps to reduce product cost and improve product quality. More specifically, to facilitate the assembly of the knob bearing 8 and the isolation sleeve 25, the bracket body 7 is provided with a third mounting base 26. The third mounting base 26 has a cylindrical structure, and the bottom of the third mounting base 26 is a stepped groove 16. The isolation sleeve 25 is fitted onto the third mounting base 26, with the bottom surface of the isolation sleeve 25 abutting against the stepped groove 16. The upper pressure cap 14 presses down on the upper end of the isolation sleeve 25 to press down on the isolation sleeve 25 and the knob bearing 8.

[0047] Furthermore, in this embodiment, the gesture-sensing rotary switch also includes an optical gear ring 27, which is mounted abutting against the upper end face of the rotary bearing 8, and the rotary ring 2 presses against the optical gear ring 27. Specifically, to improve the appearance quality of the gesture-sensing rotary switch, an optical gear ring 27 is installed on the inner side of the rotary ring 2, and the optical gear ring 27 can guide light. Figure 11 As shown, the optical gear ring 27 has multiple teeth 28 with gaps between them, allowing light to be continuously transmitted and reflected through the teeth 28, resulting in a softer light ring formed by the optical gear ring 27. An inner convex ring 29 is provided on the inner side of the knob ring 2, pressing the optical gear ring 27 against the upper surface of the knob bearing 8. The optical gear ring 27 is located on the bottom surface of the circuit board 9 and distributed along the edge of the circuit board 9. Thus, when the button backlight 11 is lit on the circuit board 9, the light simultaneously illuminates the optical gear ring 27, guiding the light to form a bright light ring that can be seen on the touch panel 10, improving the product's appearance.

[0048] Furthermore, in some embodiments, such as Figure 3 As shown, several ambient lights 30 can also be evenly distributed along the outer edge of the bottom surface of the circuit board 9. When the button backlight 11 of the circuit board 9 is lit, the ambient lights 30 are also lit simultaneously. The ambient lights 30 can also form a halo on the optical gear ring 27, which can be observed through the touch panel 10. At this time, the button backlight 11 can be surrounded by a light fence 31 to prevent the light from leaking out and to illuminate only the area of ​​the operation keys 12 on the touch panel 10. The light fence 31 can be made of sponge or EVA foam to avoid scratching the touch panel 10.

[0049] Furthermore, in this embodiment, the support body 7 has an insert groove 32, and the knob ring 2 has an inner flange 33, which is rotatably fitted into the insert groove 32. Specifically, as shown... Figure 5 and Figure 10 As shown, to facilitate the assembly of the knob ring 2 and improve the product's appearance, an insert groove 32 is provided on the upper surface of the bracket body 7. The outer wall of the insert groove 32 is formed as an outwardly protruding ring 34, which is fitted into the knob hole 6. The outer edge of the knob ring 2 forms an inwardly turned edge 33, which is fitted into the insert groove 32. The knob ring 2 is suspended on the bracket body 7 via the knob bearing 8 and is located entirely within the middle frame body 1. The outer surface of the knob ring 2 is exposed outside the middle frame body 1. By rotating the knob ring 2 using its outer surface, the speaker volume can be adjusted. Preferably, a sealing groove 35 is provided on the bracket body 7 outside the outwardly protruding ring 34. The sealing groove 35 can be filled with sealing cotton. When the bracket body 7 is securely installed to the middle frame body 1, the middle frame body 1 can press the sealing cotton into the sealing groove 35 to form a seal, providing a certain degree of dust and moisture protection. It should be noted that in some embodiments, the bracket 7 can also be set as a light guide bracket, that is, the bracket 7 is made of light guide plastic. When the bracket 7 is illuminated by the light of the button backlight 11 or the ambient light 30, a light ring is also formed on the outer convex ring 34 of the mounting groove 32, which further improves the appearance quality of the product.

[0050] Furthermore, in this embodiment, as Figure 4 and Figure 5 As shown, the bracket body 7 is provided with a first through hole 36, and the first mounting base 5 is provided with a first screw post 37. The screw passes through the first through hole 36 and is fastened to the first screw post 37. Specifically, in order to achieve a fast connection between the bracket body 7 and the middle frame body 1, multiple first through holes 36 are symmetrically provided at the four corners of the bracket body 7. Corresponding to the first through holes 36, multiple first screw posts 37 are provided on the inner side of the first mounting base 5. The screw passes through the first through holes 36 and is fastened to the first screw post 37, thereby making the bracket body 7 stably installed inside the middle frame body 1. Preferably, in order to facilitate the positioning and installation of the bracket body 7 and the middle frame body 1, a second countersunk hole 38 is formed on the upper side of the first through hole 36. The first screw post 37 is embedded in the second countersunk hole 38 to position and install the bracket body 7, which improves the convenience of product assembly and improves the production efficiency of the product.

[0051] Furthermore, in this embodiment, as Figure 5 and Figure 8As shown, the bracket body 7 is provided with a first positioning post 39, and a second through hole 40 is formed on the first positioning post 39. The circuit board 9 is provided with a third through hole 41, and a second screw post 42 is formed on the touch panel 10. The second screw post 42 passes through the third through hole 41 and engages with the first positioning post 39. A screw passes through the second through hole 40 and is fastened to the second screw post 42. Specifically, in order to facilitate the stable installation of the sensing control component 3 on the bracket body 7, four first positioning posts 39 are evenly arranged on the upper end surface of the third mounting base 26 on the bracket body 7. The second through hole 40 is formed on the first positioning post 39. The upper pressure cover 14 is provided with four fifth through holes 43 corresponding to the first positioning posts 39. The first positioning posts 39 are installed by passing through the fifth through holes 43. Four second screw posts 42 are evenly arranged on the back of the touch panel 10. Four third through holes 41 are provided on the circuit board 9 corresponding to the second screw posts 42. The second screw posts 42 pass through the third through holes 41 and engage with the first positioning post 39. Screws pass through the second through holes 40 to securely connect the second screw posts 42, thereby achieving a secure connection between the bracket body 7 and the sensing control component 3. Preferably, to facilitate the positioning and engagement of the second screw posts 42 and the first positioning post 39, a third countersunk hole 44 is formed on the first positioning post 39. The lower end of the second screw post 42 is embedded in the third countersunk hole 44 for positioning and installation, improving the ease of product assembly and increasing production efficiency.

[0052] Furthermore, in this embodiment, a touch button 45 is integrated on the circuit board 9, the touch button 45 abuts against the touch panel 10, and the button backlight 11 is arranged around the touch button 45. Specifically, as shown... Figure 8 and Figure 9 As shown, to realize the touch operation function of the gesture-sensing rotary switch, a touch button 45 is integrated on the circuit board 9. The touch button 45 is arranged corresponding to the position of the operation key 12 on the touch panel 10. The touch button 45 is installed abutting or close to the touch panel 10. When the user touches the operation key 12 on the touch panel 10, the circuit board 9 activates the touch button 45 and executes the corresponding button function. In order to clearly display the operation key 12 on the touch panel 10, a button backlight 11 is arranged around the touch button 45. Since the touch button 45 is installed corresponding to the position of the operation key 12, when the button backlight 11 is lit, the position of the operation key 12 can be highlighted.

[0053] Furthermore, in this embodiment, as Figure 1 and Figure 2As shown, a second mounting base 46 is provided on the main body 1 of the middle frame, and a switch button 47 is mounted on the second mounting base 46. The switch button 47 is electrically connected to the circuit board 9. Specifically, the switch button 47 is used to activate the circuit board 9 or the speaker. The switch button 47 is installed on the front of the main body 1 of the middle frame, and the second mounting base 46 is provided on the front of the main body 1 of the middle frame. The second mounting base 46 can be located outside the knob hole 6. The switch button 47 is fastened to the second mounting base 46 by screws. The switch button 47 is electrically connected to the circuit board 9. When the switch button 47 is turned on, the circuit board 9 is powered on. After the circuit board 9 is powered on, it conducts an induced current to the knob ring 2. The induced current is conducted to the knob bearing 8 through the spring pin 13, and then to the knob ring 2. This causes the induced current to form an induced magnetic field on the knob ring 2. When the induced magnetic field changes, the induced current also changes. At this time, the sensing chip senses the change in magnetic field and activates the button backlight 11 through the circuit board 9 to light up.

[0054] Furthermore, this embodiment of the invention also provides a speaker using the aforementioned gesture-sensing rotary switch. The gesture-sensing rotary switch is mounted on the speaker housing, and the circuit board 9 can be electrically connected to the speaker or the main control board. When the aforementioned gesture-sensing rotary switch is applied to a speaker, a large-area induction magnetic field is formed on the knob ring 2. Regardless of the direction from which the user's hand extends towards the gesture-sensing rotary switch, as long as it is near the middle frame body 1, it can be sensed and activated, thereby illuminating the button backlight 11, thus improving the activation rate. At the same time, there is no need to set or add other sensing components, effectively reducing product costs and possessing better market competitiveness. It should be noted that the gesture-sensing rotary switch can be applied to smart speakers with gesture sensing functions, as well as other gesture-sensing electronic and electrical devices.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
