[0026] The following is a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0027] The present invention provides a speaker comprising a speaker body, a display screen, and a rotating structure disposed between the speaker body and the display screen for rotating the display screen. The speaker body is a conventional sound system, including a control terminal, an amplifier, a speaker, etc., while the display screen is a component electrically connected to the speaker body and can be used to display lyrics, song titles, etc. For details, refer to the configuration of conventional speakers and will not be described in detail here.

[0028] The rotating structure includes at least the following two installation methods:

[0029] (1) The rotating structure can be installed above the speaker body, and the display screen can be installed above the rotating structure. A component for supporting the display screen can also be added between the rotating structure and the display screen, and can be added according to actual usage needs.

[0030] (2) The rotating structure can be installed on the side of the speaker body, and the display screen can be installed on the side of the rotating structure, which can specifically be the front side. In addition, a component for supporting the display screen can be added between the rotating structure and the display screen, which can be added according to actual usage requirements.

[0031] The rotating structure is: Figures 1-2As shown, it includes a first support member 1, a second support member 2, a limiting member and a rotating member 4, wherein the first support member 1 is used to connect with the audio body; the second support member 2 is used to connect with the display screen; the limiting member is used to limit and fix the first support member 1 and the second support member 2, and the second support member 2 can make a circular rotation relative to the limiting member; the rotating member 4 is arranged between the first support member 1 and the second support member 2, and is concentric with the limiting member; the second support member 2 makes a circular rotation relative to the first support member 1 through the rotating member 4 to drive the display screen to rotate.

[0032] In some embodiments, as Figure 4 As shown, the first support member 1 or the second support member 2 defines a first groove 7 that cooperates with the rotating member 4. The rotating member 4 is embedded in the first groove 7 and at least a portion is exposed outside the first groove 7, with the exposed portion abutting the other support member, so that the second support member 2 can perform circular rotational motion relative to the first support member 1. Preferably, the first groove 7 is provided on the first support member 1, and the exposed portion abuts the second support member 2. In conjunction with the subsequent polyoxymethylene rotating ring design, the user rotates the second support member 2 to rotate the display screen. The friction between the second support member 2 and the rotating ring is relatively small, and the rotation is smoother.

[0033] In some embodiments, the first support member 1 and the second support member 2 are both provided with first grooves 7 at relative positions that cooperate with the rotating member 4. A portion of the rotating member 4 is embedded in one of the first grooves 7, a portion is embedded in the other first groove 7, and a portion remains exposed outside the two first grooves 7, thereby reserving a portion of space for the second support member 2 to perform circular rotational motion relative to the first support member 1. Compared to a design with only one first groove 7, the arrangement of two first grooves 7 allows the second support member 2 to rotate more smoothly, and also provides better protection for the rotating member 4, thereby extending its service life. However, the rotating member 4 needs to be designed to be relatively thicker to keep the middle portion exposed outside the two first grooves 7, thereby ensuring that a portion of space is reserved between the first support member 1 and the second support member 2.

[0034] In some embodiments, the thickness of the rotating member 4 exposed outside the first groove 7 is 30% to 70% of the total thickness of the rotating member 4. Controlling the exposed thickness of the rotating ring prevents excessive exposure from widening the distance between the first support member 1 and the second support member 2, thereby affecting the rotation effect, while also preventing insufficient exposure from causing the distance between the first support member 1 and the second support member 2 to be too close, which would also be detrimental to long-term rotation.

[0035] In some embodiments, the diameter of the rotating member 4 is larger than the diameter of the limiting member. Providing a relatively large diameter rotating member 4 allows the rotating member 4 to travel a larger circle, further dispersing the rotational pressure of the entire second support member 2 and making the rotation smoother.

[0036] In some embodiments, as Figures 3-4 As shown, the retaining member includes a retaining ring 31 and a washer 32. The retaining ring 31 is embedded at both ends in the first support member 1 and the second support member 2, respectively, allowing the second support member 2 to rotate in a circular motion relative to the retaining ring 31. The washer 32 is disposed around the periphery of the retaining ring 31 and positioned between the first support member 1 and the second support member 2. The retaining ring 31 also includes a through-hole for passing electrical wires to achieve electrical connection between the display screen and the speaker body. Because there is a certain gap between the first support member 1 and the second support member 2, the addition of the washer 32 fills this gap, further improving the retaining and fixing effect of the retaining ring 31 on the first and second support members 1 and 2. However, it should be noted that when the retaining ring 31 is embedded in the second support member 2, some clearance should be left between the periphery of the retaining ring 31 and the second support member 2 to ensure the second support member 2 can rotate in a circular motion.

[0037] In some embodiments, the rotating member 4 is a polyoxymethylene rotating ring. Polyoxymethylene material (POM) is a hard and dense material with a smooth and shiny surface. It has the characteristics of high strength, high rigidity, good elasticity, and good wear resistance. When it is used as the preparation material of the rotating member 4, when it abuts against the surface of another support member, compared with conventional metal materials, the rotating ring will not produce the harsh sound caused by bimetallic friction when rubbing against the other support member during rotation, which can effectively reduce the damage to the abutting support member, and does not require the use of a large amount of lubricating oil, the surface is cleaner, and assembly is easier; in addition, it has good wear resistance, sufficient hardness and rigidity, and compared with general PP plastic products, it can still maintain effective abutment and rotation with another support member after long-term rotation. Correspondingly, the first groove 7 is a ring groove structure so that a part of the rotating ring is embedded therein.

[0038] In some embodiments, the structure further includes a retaining member 5 provided on the first support member 1 or the second support member 2, and a limiting groove 6 matching the retaining member 5; the retaining member 5 and the limiting groove 6 move relative to each other following the circumferential rotation of the second support member 2. Specifically, the limiting groove 6 can be provided on the second support member 2, and the retaining member 5 can be provided on the first support member 1; the limiting groove 6 moves relative to the retaining member 5 following the circumferential rotation of the second support member 2.

[0039] In some embodiments, the limiting groove 6 is composed of a plurality of limiting bead grooves, which are arranged at intervals and form a limiting arc groove or a limiting ring groove concentric with the rotating member 4 .

[0040] By employing a plurality of spaced-apart retaining bead grooves, the retaining member 5 emits a pleasant rotating sound as it moves relative to the retaining groove 6, allowing the user to truly feel the rotation of the second support member 2. Furthermore, if no rotational thrust is provided for the display screen, the retaining bead grooves can also serve as a retaining mechanism, keeping the display screen securely in the desired rotational position. The retaining member 5 can be a spring-loaded ball bearing, the elasticity of which further facilitates the relative movement of the retaining member 5 and the retaining groove 6.

[0041] Preferably, the diameter of the arc groove or ring groove formed by the plurality of limiting bead grooves is larger than the diameter of the polyoxymethylene rotating ring. By setting the limiting groove 6 with a relatively larger diameter, more limiting bead grooves can be arranged, which can more flexibly control the orientation of the display screen after rotation.

[0042] In some embodiments, the first support member 1 further defines a second groove 8, and the second support member 2 is provided with a limiting post 9 that cooperates with the second groove 8, or the second support member 2 defines a second groove 8, and the first support member 1 is provided with a limiting post 9 that cooperates with the second groove 8, and the second groove 8 is an arc groove or an annular groove. The design of the arc groove or annular groove can be determined according to the maximum rotation angle of the display screen. For example, when the maximum rotation angle of the display screen is 180 degrees, the second groove 8 can be designed as a semicircular arc groove (such as Figure 4 When the maximum rotation angle of the display screen is 360 degrees, the second groove 8 can be designed as a ring groove. Preferably, the diameter of the second groove 8 is smaller than the diameter of the polyoxymethylene rotating ring.
