[0047] Currently, users have higher and higher requirements for audio speakers, and there are also more and more types of audio speakers. Buttons are an important part of the audio speaker structure. The functions of traditional audio speaker buttons are relatively single, often only able to achieve a single function such as rotary adjustment or press-and-switch. Some buttons can rotate while being pressed, but their specific structures cannot effectively separate and distinguish the rotary and pressing actions, making it difficult to meet the actual requirements during use.

[0048] The present utility model proposes a button structure and an electronic product to solve the above problems.

[0049] Please refer to Figures 1 to 3, in an embodiment of the present utility model, the disclosed button structure 100 is different from the traditional button structure 100. Most of the traditional button structures 100 are either a single pressing structure or a single rotating structure. In this embodiment, the rotating function of the rotary button and the pressing function of the pressing button are integrated on the same button structure 100, so that the same button structure 100 has the ability to perform both rotary adjustment and pressing adjustment at the same time, which is beneficial to the integration of button functions and the compact design of equipment specifications. Specifically, the button structure 100 mainly includes an encoder 1, a knob 2 and a button 3. The inner ring portion 11 and the outer ring portion 12 of the encoder 1 can rotate coaxially relative to each other. The knob 2 is fixedly connected to the outer ring portion 12. During use, by screwing the outer ring portion 12, relative rotation can be generated between the outer ring portion 12 and the inner ring portion 11, thereby realizing the rotary adjustment function of the button structure 100. Additionally, the button 3 has a movement stroke along the axis direction of the inner ring portion 11 on the inner wall of the inner ring portion 11, and can realize the pressing function of the pressing button. In this embodiment, the rotary function and the pressing function of the traditional button are integrated on one button structure 100. During actual use, the functions of turning on / off and adjusting / switching can be realized through one button. This button structure 100 not only has a good integration degree, but also the structures for realizing the rotary and pressing functions have complete and independent motion states, and are more stable in structure, which is beneficial to improving the user experience. Moreover, in the specific installation structure, it can also achieve a good effect of saving installation space.

[0050] Specifically, the rotary button includes a first hole section 21 with a larger aperture and a second hole section 22 with a smaller aperture. The second hole section 22 is mainly an installation structure for forming a fixed connection with the outer ring portion 12. The corresponding button includes a pressing portion 31 with a larger cross-section and a connecting portion 32 with a smaller cross-section. Among them, the connecting portion 32 is movably arranged inside the inner ring portion 11, and the pressing portion 31 is arranged inside the first hole section 21. Since the cross-sectional area at the first hole section 21 is larger, a relatively large pressing space can be provided as much as possible for the operator to better contact the pressing portion 31 for operation.

[0051] When performing a pressing operation, pressing one end of the pressing portion 31 will drive the connecting portion 32 to slide downward on the inner side wall of the inner ring portion 11. In this embodiment, a shock-absorbing pad is provided on the connecting portion 32 at a position corresponding to between the pressing portion 31 and the step surface 23. On the one hand, the shock-absorbing pad can absorb part of the vibration generated during the use of the entire button structure 100. On the other hand, it has the effect of deformation recovery, which can prompt the connecting portion 32 to perform a reset movement upward on the inner wall of the inner ring portion 11, thereby driving the pressing portion 31 to automatically reset. It can be imagined that the shock-absorbing pad should preferably be made of a flexible rebound material, including but not limited to a silicone pad or a rubber pad, etc.

[0052] It can be imagined that there is a relative movement effect between some structures in the button structure 100, and it is difficult to achieve a very tight fit. Therefore, there is generally a certain gap between the structures that move relative to each other. In a vibrating environment, noise is easily generated due to the collision between the structures. In this embodiment, a circular skirt portion 41 is formed by protruding outward from the side of the circular shock-absorbing pad 4, and the circular skirt portion 41 protrudes laterally from the pressing portion 31. With such a setting, during the process that the pressing portion 31 moves toward the inner wall of the first hole section 21 due to vibration, the circular skirt portion 41 will first come into contact with the inner wall of the first hole section 21. Because the circular skirt portion 41 and the circular shock-absorbing pad 4 are both made of flexible materials, noise can be effectively avoided during the contact process. In particular, when the button structure 100 is applied to a music playing device, it can eliminate the vibration noise on the button 3 and the knob 2 when playing music, which is beneficial to improving the user experience.

[0053] Specifically, when installing the circular shock-absorbing pad 4, the first mating convex portion 321c on the circular shock-absorbing pad 4 is fixed in the first circular limiting groove 311 in a bonding manner to limit the movement of the circular shock-absorbing pad 4. In addition, a second circular limiting groove 24 and a second circular mating convex portion 43 that cooperate with each other are provided between the circular shock-absorbing pad 4 and the step surface 23. When the knob 2 rotates, the second circular mating convex portion 43 slides in contact with the bottom of the second circular limiting groove 24, and the reset movement of the pressing portion 31 is mainly driven by the deformation of the second circular mating convex portion 43.

[0054] After the plastic molded part is molded, the surface is prone to shrinkage and form water marks. In order to improve the aesthetics of the outer exposed end of the pressing portion 31, a decorative plate 7 is provided on the side of the pressing portion 31 facing away from the connecting portion 32 (the operation side of pressing), and the decorative plate 7 is fixedly connected to the pressing portion 31 in a bonding manner.

[0055] The connecting part 32 is installed inside the inner ring part 11 and can slide along the inner wall of the inner ring part 11. At the same time, the effect of pressing down and contacting needs to be achieved. Specifically, it mainly includes an outer annular guiding part 321 and a pressing core part 322. The outer wall of the outer annular guiding part 321 is slidably connected to the inner wall of the inner ring part 11, so that the connecting part 32 can move along the axis direction of the inner ring part 11 on the inner wall of the inner ring part 11. One end of the pressing core part 322 extends outwards from the opening 321b to the outside of the outer annular guiding part 321. When the pressing part moves downwards, the downward end of the pressing core part 322 abuts against the contact switch 6 inside the electronic product, thereby realizing the functional effect of a traditional pressing button.

[0056] Wherein, a guiding structure is provided between the outer ring guiding part and the inner ring part 11 to guide the movement of the connecting part 32. Specifically, a plurality of convex ribs 321a on the outer annular guiding part 321 cooperate with a plurality of guiding grooves 112 on the inner wall of the inner ring part 11, enabling the connecting part 32 to move along the axis direction of the inner ring part 11 and restricting its rotation around the axis.

[0057] A plurality of rubber scooping parts are provided on both the pressing core part 322 and the inner ring part 11. Firstly, it can avoid the shrinkage from affecting the appearance and fit of the components. Secondly, it can save production materials as much as possible while ensuring the structural strength.

[0058] The connecting part 32 moves on the inner wall of the inner ring part 11, and a corresponding limiting structure is provided between the two to prevent the connecting part 32 from detaching from the inner ring part 11. Specifically, when the second annular mating convex part 43 contacts the bottom of the second annular limiting groove 24, the convex part 321c on the outer wall of the outer annular guiding part 321 abuts against one end of the limiting protrusion 111 away from the pressing part 31. At this time, the upward movement stroke of the connecting part 32 along the axis direction of the inner ring part 11 in the inner ring part 11 can be restricted, thereby ensuring the installation stability of the button 3 on the inner ring part 11.

[0059] The present utility model also discloses an electronic product, which includes a button structure 100. The button structure 100 refers to the above embodiments. Since the button structure 100 of this electronic product adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0060] Wherein, the electronic product further includes a housing (not shown), a main circuit board 5, and a touch switch 6. Specifically, the pressing portion 31 and the knob 2 in the button structure 100 are disposed outside the housing for relevant personnel to operate. The inner ring portion 11 is fixedly connected to the main circuit board 5. During the process of rotating the knob 2, the inner ring portion 11 rotates relative to the outer ring portion 12, thereby realizing the adjustment and switching function. When the exposed end of the pressing portion 31 is pressed and the downward pressing core portion 322 and the contact portion 61 exert forces on each other, the touch switch 6 can realize the pressing and switching function.

[0061] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
