[0032] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0033] The following is for reference. Figures 1-7 The present invention describes a knob-generating sound device 100 according to an embodiment of the present invention, and also proposes a seat according to an embodiment of the present invention.

[0034] Reference Figures 1-7 As shown, the knob sound-generating device 100 of this utility model embodiment includes: a rotating base 10, a knob assembly 20, and a second sound-generating element 30.

[0035] The two ends of the rotating base 10 are respectively connected to the massage mechanism, which is used to massage the user.

[0036] The knob assembly 20 includes a knob 21, a rotating shaft 22, and a first sound-emitting element 23. One end of the knob 21 is connected to the rotating shaft 22, and the other end of the rotating shaft 22 is connected to the rotating base 10. Specifically, the knob 21 can be rotated by the user. The user rotates the knob 21, causing the rotating shaft 22 to rotate. One end of the rotating shaft 22 is connected to the rotating base 10, and both ends of the rotating base 10 are connected to the massage mechanism. Therefore, the force exerted by the user rotating the knob 21 can ultimately be applied to the massage mechanism to achieve the relevant operation.

[0037] A first sound-emitting element 23 is mounted on a rotating shaft 22 and has multiple first sound-emitting sections. A second sound-emitting element 30 is mounted on a rotating base 10 and is positioned opposite to the first sound-emitting sections. The second sound-emitting element 30 is configured to strike the first sound-emitting sections to produce sound when the knob 21 is rotated. Thus, when the user rotates the knob 21, the first sound-emitting element 23 mounted on the rotating shaft 22 rotates with the shaft 22. During rotation, the second sound-emitting element 30 strikes the first sound-emitting sections, producing sound.

[0038] The second sound-emitting element 30 strikes the first sound-emitting part to produce sound, which can provide operation feedback to the user. The sound indicates that the knob 21 has been turned successfully. In situations where vision is limited, such as when the user operates blindly, sound can replace vision to confirm whether the operation of the knob 21 has taken effect.

[0039] Furthermore, the first sound-emitting component 23 is provided with multiple first sound-emitting parts. The sound emitted by the second sound-emitting component 30 when striking the first sound-emitting part corresponds to the multiple first sound-emitting parts inside. Each sound represents striking a first sound-emitting part, which makes it easy for the user to accurately understand the rotation of the knob 21 and avoid incorrect adjustment caused by continuous and too fast rotation.

[0040] The second sound-emitting component 30 can be made of metal, plastic, rubber or other elastic materials, or a composite material combining metal and plastic or metal and rubber. Different materials produce different timbres, which enhances the auditory pleasure of the user when turning the knob 21, makes the device more stylish, and enhances the sense of ritual when the user operates it.

[0041] Therefore, by striking the first sound-emitting part with the second sound-emitting element 30 to produce sound, operation feedback can be provided to the user. Sound can replace visual confirmation of whether the operation of the knob 21 is effective, making it easier for the user to accurately understand the rotation of the knob 21, avoiding incorrect adjustment caused by continuous and too fast rotation, while enhancing the auditory pleasure of the user when turning the knob 21, making the device more aesthetically pleasing, and enhancing the sense of ritual when the user operates it.

[0042] Reference Figures 2-5 As shown, the rotating base 10 is provided with a first receiving groove 11, and a portion of the second sound-emitting element 30 is disposed within the first receiving groove 11. The knob sound-emitting device 100 also includes an elastic element 41, which abuts against the inner wall of the second sound-emitting element 30 and the first receiving groove 11. Specifically, the elastic element 41 can be a spring, with one end abutting against the inner wall of the first receiving groove 11 and the other end abutting against the second sound-emitting element 31. The elastic force of the elastic element 41 can cause the second sound-emitting element 30 to strike the first sound-emitting element, thereby producing sound.

[0043] Reference Figures 5-6 As shown, a clearance opening 12 is provided on the first receiving groove 11. The clearance opening 12 is disposed opposite to the first sound-emitting part, and another part of the second sound-emitting element 30 protrudes relative to the clearance opening 12. That is, the bottom of the second sound-emitting element 30 protrudes relative to the clearance opening 12, so that the second sound-emitting element 30 contacts the first sound-emitting part, and the remaining part of the second sound-emitting element 30 is confined within the receiving groove. This can prevent the position of the second sound-emitting element 30 from shifting, which would prevent it from striking the first sound-emitting part and improve the stability of the rotating sound-emitting device.

[0044] Reference Figures 5-6As shown, the second sound-emitting component 30 is provided with a second sound-emitting part 31, which protrudes relative to the clearance opening 12, and the cross-section of the second sound-emitting part 31 in the axial direction of the rotating shaft 22 is triangular. That is to say, the contact area between the second sound-emitting part 31 and the first sound-emitting part is small, and the sound emitted during the impact propagates from the narrow end to the surroundings. As the area of ​​the second sound-emitting part 31 gradually increases, the sound propagation range increases accordingly, avoiding the concentration of sound waves, thereby improving the sound propagation efficiency and coverage.

[0045] Reference Figure 3 and Figure 5 As shown, the first sound-generating element 23 includes a gear disk 24 and a disc 25, which are connected to each other in the axial direction of the rotating shaft 22. The gear disk 24 has multiple first sound-generating parts, and the outer diameter of the disc 25 is larger than that of the gear disk 24. Specifically, rotation of the rotating shaft 22 drives the gear and gear disk 24 to rotate. During the rotation of the gear, the second sound-generating part 31 strikes the first sound-generating parts on the gear disk 24 to produce sound. Further, the first sound-generating parts are multiple tooth gaps on the gear disk 24. During the rotation of the gear disk 24, the tooth tip is higher than the tooth gap, causing the second sound-generating element 30 to move upward. The elastic element 41 abuts against and compresses the first receiving groove 11. When the second sound-generating element 30 corresponds to the tooth gap position, the elastic element 41 provides elastic force to cause the second sound-generating element 30 to strike the tooth gap downward, thereby producing sound.

[0046] Reference Figure 7 and Figure 5 As shown, the rotating base 10 is provided with a second receiving groove 13 and a third receiving groove 14, which are interconnected. The geared disk 24 is disposed in the second receiving groove 13, and the disc 25 is disposed in the third receiving groove 14. That is to say, the second receiving groove 13 and the third receiving groove 14 on the rotating base 10 form a stepped surface. The outer diameter of the disc 25 is larger than the outer diameter of the geared disk 24. The disc 25 mates with the third receiving groove 14 with a larger diameter, and the geared disk 24 mates with the second receiving groove 13 with a smaller diameter. The stepped surface can help the first sound-generating element 23 to be accurately positioned during assembly and can also prevent the first sound-generating element 23 from shifting during operation.

[0047] Reference Figure 7As shown, the knob 21 is provided with a first circumferential limiting part 26, the rotating shaft 22 is provided with a second circumferential limiting part, and the first sound-emitting element 23 is provided with a third circumferential limiting part. The second circumferential limiting part, the first circumferential limiting part 26, and the third circumferential limiting part are mutually limiting and engaged. That is, the knob 21 is provided with a polygonal hole that mates with the rotating shaft 22. The rotating shaft 22 is a polygonal rotating shaft 22, and the first sound-emitting element 23 is also provided with a polygonal hole that mates with the rotating shaft 22. The polygonal rotating shaft 22 does not have the same continuous rotation capability as a circular shaft. The rotating shaft 22 is restricted after rotating at a certain angle. By engaging the polygonal rotating shaft 22 with the corresponding polygonal hole, accidental rotation of the rotating shaft 22 is prevented. During initial assembly, it is ensured that the rotating shaft 22, the knob 21, and the first sound-emitting element 23 are in the correct positions to ensure that the knob sound-emitting device 100 remains stable during operation. In this embodiment, a hexagonal rotating shaft 22 and a hexagonal hole are used.

[0048] The knob 21, the rotating shaft 22, and the first sound-generating component 23 are all integrally molded. This integral molding structure saves the steps of separate manufacturing and assembly, simplifies the production process, saves assembly time, eliminates errors caused by connection errors, loose assembly, or tolerance issues in traditional assembly processes, and reduces weaknesses at joints, thereby improving the overall strength and durability of the structure.

[0049] Reference Figures 2-3 As shown, the rotating base 10 includes a first housing 15, a second housing 16, and a reciprocating component. The first housing 15 and the second housing 16 are fastened together. The reciprocating component is disposed inside the first housing 15 and the second housing 16 and is connected to the rotating shaft 22 for transmission. The reciprocating component is also connected to the massage mechanism for transmission.

[0050] The first housing 15 is provided with a first snap-fit ​​part 17, and the second housing 16 is provided with a second snap-fit ​​part 18. The first snap-fit ​​part 17 and the second snap-fit ​​part 18 are snapped together so that the first housing 15 and the second housing 16 are fastened together.

[0051] Alternatively, in some embodiments, a first positioning part is provided on the first housing 15, and a second positioning part is provided on the second housing 16. The first positioning part and the second positioning part are positioned and engaged so that the first housing 15 and the second housing 16 are fastened together.

[0052] According to a second aspect of the present invention, a seat includes a backrest and a massage assembly, the massage assembly being disposed on the backrest to provide a massage function to the user.

[0053] The massage assembly includes a support, a knob-generating device 100, and a massage mechanism. The knob-generating device 100 is mounted on the support, and the massage mechanism is vertically mounted on the support and connected to the knob-generating device 100. Specifically, the rotating base 10 also includes a drive assembly, the reciprocating element of which can be a traction cable. The massage mechanism is vertically mounted on the support, and the traction cable connects the drive assembly and the massage mechanism. The drive assembly selectively drives the massage mechanism to move up and down via the traction cable, thereby adjusting the position of the massage mechanism on the support.

[0054] This massage mechanism is a product of existing technology. Different types of massage mechanisms can be selected according to different user needs, and it has good adaptability.

[0055] Furthermore, since the traction line connects the drive assembly and the massage mechanism, the drive assembly can provide an upward pulling force to the massage mechanism through the traction line, and can also provide a downward pulling force to the massage mechanism through the traction line, thereby realizing the raising and lowering of the massage mechanism.

[0056] Furthermore, the drive assembly and the massage mechanism are connected by a traction cable, which avoids friction between the drive assembly and the massage mechanism, prevents vibration and impact during transmission, and reduces the number of parts and the volume occupied.

[0057] In this way, the massage mechanism can rise and fall, allowing users to adjust the massage position to their liking and enhancing the user experience. When adjusting the position of the massage mechanism, users can confirm the effectiveness of the operation and the degree of adjustment through the sound feedback emitted by the knob sound device 100, avoiding continuous or incorrect adjustments and improving the convenience of operation.
