[0002] A loudspeaker is a device that converts electrical energy into sound energy. It works on the principle of vibration generated by electromagnetic induction, converting electrical energy into sound energy through an "electricity-force-sound" conversion process. To meet diverse usage needs and provide a wide range of functions, loudspeakers can be equipped with displays, combining audio playback and visual display to enhance the user's audiovisual experience. A loudspeaker typically includes a housing, with the display mounted on it.

[0003] However, the display screen is usually at a fixed angle, which makes it inconvenient for users. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a flip screen structure and a speaker. The flip screen can be flipped and adjusted to a suitable angle, allowing users to adjust the angle as needed, which improves ease of use.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0006] In a first aspect, the present invention provides a flip screen structure, including a base; a flip screen rotatably mounted on the base; and a friction component disposed between the base and the flip screen, wherein the friction component causes the flip screen to self-lock due to friction.

[0007] In some implementations, the flip screen includes a bottom shell that is rotatably connected to the base. The bottom shell has a guide groove, and when the flip screen rotates, the friction assembly moves along the guide groove.

[0008] In some implementations, the base is provided with a connecting seat, and the connecting seat is provided with a rotating shaft; the bottom shell is provided with a rotating hole, and the rotating shaft passes through the rotating hole and is rotatably connected to the bottom shell.

[0009] In some implementations, the friction assembly includes a friction shaft disposed on the base, the friction shaft including a guide end that is slidably connected to the bottom shell within the guide groove; and a damping sleeve fitted onto the guide end, the outer wall of the damping sleeve abutting against the inner wall of the guide groove.

[0010] In some implementations, the friction shaft is provided with a limiting groove for cooperating with the bottom shell to restrict the movement of the damping sleeve, and the damping sleeve is disposed in the limiting groove.

[0011] In some implementations, an auxiliary positioning component for assisting in locking the flip screen is provided between the friction shaft and the base.

[0012] In some implementations, the flip screen includes a top shell disposed on the bottom shell and detachably connected to the bottom shell; a display panel disposed on the top shell; and a PCB board disposed inside the bottom shell.

[0013] In some implementations, the base has a receiving groove adapted to the flip screen, and the rotating screen is rotatably disposed in the receiving groove.

[0014] Secondly, this utility model provides a speaker, including the aforementioned flip-screen structure.

[0036] Example 1:

[0037] Please see the appendix Figures 1-3 The flip screen structure of this utility model includes a base 1, a flip screen 2 rotatably mounted on the base 1, and a friction component 3 between the flip screen 2 and the base 1. The flip screen 2 can be flipped to a suitable angle for the user to view, thus improving the convenience of use.

[0038] Please see the appendix Figures 4-7 In a preferred embodiment, the flip screen 2 includes a bottom shell 21, on which a top shell 22 is disposed. The bottom shell 21 is rotatably connected to the base 1, and the bottom shell 21 and the top shell 22 are fitted together and detachably connected. As shown in some specific embodiments, a connecting sleeve 214 is provided inside the bottom shell 21, and a connecting post 221 is provided on the side of the top shell 22 near the base 1. The connecting post 221 and the connecting sleeve 214 are interference-fitted to achieve quick assembly and disassembly of the bottom shell 21 and the top shell 22. In other specific embodiments, the bottom shell 21 and the top shell 22 can be assembled by bolts. Specifically, a protrusion 216 is provided on the inner wall of the bottom shell 21, and a notch 222 adapted to the protrusion 216 is provided on the top shell 22. When the top shell 22 and the bottom shell 21 are fitted together, the protrusion 216 is inserted into the notch 222, and the top shell 22 is positioned.

[0039] A display panel 23 is provided on the top shell 22. Specifically, the display panel 23 is preferably, but not limited to, made of acrylic sheet, and the display panel 23 can be bonded to the top shell 22. In some specific embodiments shown, a side groove 213 is provided on the bottom shell 21. When the top shell 22 and the bottom shell 21 are closed, the display panel 23 is embedded in the side groove 213.

[0040] Please see the appendix Figure 8 A PCB board 24 is disposed between the bottom shell 21 and the top shell 22. Specifically, the PCB board 24 has a first connecting hole 241. A connecting post 221 passes through the first connecting hole 241 and is interference-fitted with a connecting sleeve 214, thus fixing the PCB board 24 inside the bottom shell 21 for easy assembly and disassembly. Furthermore, the PCB board 24 has a second connecting hole 242. A positioning post 215 is disposed inside the bottom shell 21. When the PCB board 24 is placed inside the bottom shell 21, the positioning post 215 passes through the second connecting hole 242, and the PCB board 24 is initially positioned.

[0041] The flip screen has a simple structure and is easy to disassemble and assemble, which facilitates the maintenance of the flip screen 2.

[0042] Please see the appendix Figure 9 In a preferred embodiment, the base 1 is provided with a receiving groove 11. Specifically, the receiving groove 11 is a groove that is adapted to the flip screen 2. The flip screen 2 can be flipped to be stored in the receiving groove 11. When the user needs to use the flip screen 2, the flip screen 2 can be flipped out of the receiving groove 11 and adjusted to a suitable angle for transportation, etc.

[0043] Please see the appendix Figure 10 In a preferred embodiment, the bottom shell 21 includes a rotating end, and a guide groove 211 is formed on the rotating end of the bottom shell 21. As shown in some specific embodiments, the guide groove 211 is an arc-shaped groove. When the flip screen 2 rotates, the friction component 3 moves along the guide groove 211 and realizes timely locking of the flip screen 2. Specifically, the base 1 has a clearance hole 113 formed on the bottom wall of the receiving groove 11. When the flip screen 2 rotates, the rotating end of the bottom shell 21 rotates within the clearance hole 113, so that the bottom shell 21 rotates relative to the friction component 3 and the base 1.

[0044] Please see the appendix Figures 1-3 When the flip screen 2 is rotated, the bottom shell 21 rotates relative to the pivot 41 to adjust to a suitable angle. The friction component 3 locks the flip screen 2 by friction, which makes it easier for users to view the content on the flip screen 2. Compared with traditional displays, it improves the convenience and flexibility of use.

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the friction component 3 of this utility model. Please refer to [link / reference]. Figures 9-13 .

[0047] Please see Figure 9 In this embodiment, the base 1 has a first through hole 111 and a second through hole 112 on the inner wall of the receiving groove 11. The base 1 is provided with a connecting seat 4 on one side of the first through hole 111 and the second through hole 112. The connecting seat 4 is located on the side of the base 1 away from the receiving groove 11. As shown in some specific embodiments, the connecting seat 4 is detachably connected to the base 1, such as by bolts.

[0048] Please see Figures 10-13In a preferred embodiment, the friction assembly 3 includes a friction shaft 31. Specifically, the friction shaft 31 is mounted on the connecting seat 4. The friction shaft 31 includes a guide end 311, which passes through the second through hole 112 into the guide groove 211 and moves along the guide groove 211 when the flip screen 2 flips. A limiting groove 312 is formed in the guide end 311 of the friction shaft 31. The limiting groove 312 is a groove formed annularly along the surface of the friction shaft 31. A damping sleeve 32 is provided in the limiting groove 312 of the friction shaft 31. The damping sleeve 32 is fitted onto the friction shaft 31, and the outer wall of the damping sleeve 32 abuts against the inner wall of the guide groove 211, which can increase the friction between the guide end 311 and the inner wall of the guide groove 211, so that the flip screen 2 can achieve self-locking through friction. The limiting groove 312 can cooperate with the bottom shell 21 to restrict the free movement of the damping sleeve 32.

[0049] As shown in some specific embodiments, the damping sleeve 32 is provided with a reinforcing rib 321. Specifically, the reinforcing rib 321 is an annular protrusion, and its outer wall abuts against the inner wall of the guide groove 211. The reinforcing rib 321 helps to extend the service life of the damping sleeve 32, and at the same time, it forms a suitable friction between the damping sleeve 32 and the bottom shell 21 so that the flip screen 2 can rotate smoothly. In other specific embodiments, an extension groove is formed on the inner wall of the guide groove 211, and the reinforcing rib 321 is embedded in the extension groove. The cooperation between the reinforcing rib 321 and the extension groove can further guide and limit the rotation of the flip screen 2.

[0050] In a preferred embodiment, a rotating shaft 41 is provided on the connecting seat 4. The rotating shaft 41 is located on one side of the friction shaft 31. The rotating shaft 41 passes through the first mounting hole and into the receiving groove 11. The first mounting hole can limit the rotation of the rotating shaft 41. A rotating hole 212 is provided on the bottom shell 21. The rotating shaft 41 passes through the first mounting hole and is installed in the rotating hole 212. When the flip screen 2 is flipped, the bottom shell 21 rotates relative to the rotating shaft 41.

[0051] Pull the flip screen 2 to make the flip screen 2 rotate. The bottom shell 21 rotates relative to the rotating shaft 41. The base 1 rotates relative to the friction shaft 31 and the damping sleeve 32 at the guide groove. That is, the guide end 311 and the damping sleeve 32 can move along the guide groove 211. The bottom shell 21 is locked by the friction between it and the damping sleeve 32. The friction assembly 3 has a simple structure and is easy to operate.

[0052] Example 3:

[0053] The difference between this embodiment and the above embodiments is that this embodiment further optimizes the structure of the friction component 3 of the present invention.

[0054] In this embodiment, a fixed sleeve is provided on the connecting seat 4. The friction shaft 31 passes through the fixed sleeve and is slidably connected to the fixed sleeve. A groove is provided on the inner wall of the fixed sleeve. Specifically, the length direction of the groove is consistent with the axial direction of the friction shaft 31. A slider is provided on the outer wall of the friction shaft 31. The slider is slidably connected to the fixed sleeve in the groove. When the friction shaft 31 slides relative to the fixed sleeve, the slider slides along the groove to limit the movement of the friction shaft 31.

[0055] An elastic element is provided between the friction shaft 31 and the fixed sleeve. The elastic element is preferably, but not limited to, a spring. One end of the elastic element is connected to the fixed sleeve in the compression direction, and the other end is connected to the friction shaft 31. When the guide end 311 of the friction shaft 31 passes through the guide groove 211, the elastic element is compressed to provide a further clamping force between the friction shaft 31 and the inner wall of the guide groove 211. The elastic element presses the guide end 311 of the friction shaft 31 and the damping sleeve 32 against the inner wall of the guide groove 211, which can improve the stability of the flip screen 2 when locked.

[0056] Example 4:

[0057] This embodiment provides a loudspeaker based on the above embodiments.

[0058] A speaker, including the aforementioned flip-screen structure, please refer to [link / reference]. Figure 9 In a preferred embodiment, the base 1 has a storage slot 12. Specifically, the storage slot 12 is a long strip groove that is connected to the receiving slot 11. The storage slot 12 can hold items. When a tablet computer is placed in the storage slot 12, the support angle of the tablet computer can be adjusted synchronously by adjusting the angle of the flip screen 2. When the flip screen 2 is flipped away from the receiving slot 11, one side of the tablet computer is supported on the bottom of the base shell 21, and the other side is supported in the storage slot 12. The flip screen structure works with the storage slot 12 to adjust the placement angle of the tablet computer, which is beneficial for viewing the flip screen 2 and the tablet computer at the same time, improving the convenience of use.

[0059] Specifically, the base 1 is provided with magnets, coils, a vibrating diaphragm, and a centering support plate. It is understood that the way the loudspeaker converts electrical energy into sound energy is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.

[0060] The flip-screen design allows the speaker to be used in different scenarios, such as dimly lit or brightly lit environments, which helps users view the content on the flip-screen 2. Users can adjust the angle according to their own needs.
