Description

Technical Field

[0001] This utility model relates to the field of loudspeaker device technology, specifically to a polygonal external magnetic conductive sheet. Background Technology

[0002] Loudspeakers are widely used in audio systems and electronic products such as televisions. Most existing loudspeakers consist of a T-iron, magnet, washer, voice coil, frame, and diaphragm. The washer is usually a flat washer, also known as a magnetic conductor. Common magnetic conductors are generally molded in one piece, requiring replacement of the entire unit if damaged. Furthermore, to ensure minimal sound distortion, the magnetic conductor is generally quite thick, resulting in higher costs, which needs improvement. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a polygonal external magnetic conductive sheet, including a first part and a second part. The first part has a T-shaped cross-section and a through hole formed along the axial direction at its longitudinal end. The second part includes a ring body and protrusions that bulge outward at intervals on the peripheral wall of the ring body. Protruding fixing blocks are provided at intervals on the inner peripheral wall of the ring body. A fixing groove is provided on the peripheral wall of the longitudinal end of the first part. In the second part, the ring body is fitted onto the longitudinal end of the first part and the fixing blocks are embedded in the fixing groove. The bottom surface of the ring body in the second part abuts against the transverse end of the first part.

[0005] In this design, the magnetic sheet is assembled from a first part and a second part. The second part is fitted onto the longitudinal end of the first part by a ring, and the transverse end of the first part abuts against the supporting ring. A fixing block is embedded in a fixing groove to fix the ring in the second part to the first part. The spaced protrusions help reduce weight and lower costs. The first and second parts of the assembly structure can be replaced as needed during subsequent maintenance, and the material of the second part, which plays a major supporting and fixing role, can be selected according to requirements, which helps to reduce costs.

[0006] Furthermore, the thickness of the ring in the second segment is consistent with the height of the longitudinal end in the first segment, and the outer diameter of the ring in the second segment is larger than the diameter of the transverse end in the first segment, which helps to improve structural strength, and limiting the size of the transverse end helps to reduce weight.

[0007] Furthermore, the cross-section of the fixing block is trapezoidal, but it can also be triangular, rectangular, or other shapes.

[0008] Furthermore, a fixing hole is provided on the protrusion along the thickness direction to facilitate the connection of mechanisms such as springs in the speaker through screws or the like.

[0009] Furthermore, a groove is provided on the top surface of the protrusion, and the two ends of the groove extend to the opposite side of the protrusion. A fixing hole is provided on the bottom wall of the groove. During installation, the side of the spring is inserted into the groove for pre-positioning, and then the spring can be fixed by screws or the like engaging with the fixing hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The magnetic conductive sheet in this utility model is a first split and a second split assembled structure. The material of the second split can be selected according to the needs, which helps to reduce the molding cost and subsequent maintenance cost. The spaced protrusions help to reduce weight and further reduce costs. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 , Figure 2 As shown, in this example, the polygonal external magnetic conductive sheet includes a first part 1 and a second part 2. The magnetic conductive sheet adopts a split assembly structure, wherein the cross section of the first part 1 is T-shaped and its longitudinal end 11 is formed with a through hole 12 along the axial direction, and it is fitted onto the T-iron of the speaker through the through hole 12.

[0020] The second component 2 includes a ring 21 and protrusions 22 that bulge outwards at intervals along the periphery of the ring 21. The shape of the protrusions 22 can be selected according to requirements, such as a rectangular shape in this example, but arc-shaped, triangular, or other shapes can also be selected. Protruding fixing blocks 23 are formed at intervals along the inner periphery of the ring 21, such as a trapezoidal cross-section, but triangular, rectangular, or other shapes can also be used. Corresponding fixing grooves are formed at intervals along the longitudinal end periphery of the first component 1. During assembly, the ring 21 of the second component 2 is fitted onto the longitudinal end 11 of the first component 1, and the fixing blocks 23 are embedded in the fixing grooves. The first and second components are fixed together by this fitting and fixing. Furthermore, the bottom surface of the ring 21 in the second component 2 abuts against the transverse end of the first component 1, which helps improve stability under the support of the transverse end.

[0021] In this example, the protrusion 22 is spaced out, which helps reduce weight. Furthermore, the second part 2 can be made of a different material than the first part, such as a higher-strength material, which helps reduce costs. If the second part is damaged during subsequent use, only the second part needs to be replaced, helping to reduce maintenance costs.

[0022] In this example, the thickness of the ring 21 in the second part 2 is the same as the height of the longitudinal end in the first part 1, so that the top ends are flush. The outer diameter of the ring 21 in the second part 2 is larger than the diameter of the transverse end 10 in the first part 1, which helps to reduce the amount of the first part used.

[0023] To facilitate the connection between the protrusion and the spring, in this example, a fixing hole 25 is formed along the thickness direction on the protrusion 22. During installation, the side of the spring is placed on the protrusion, and then the spring and the magnetic sheet are fixed together by screws. Preferably, a groove 24 is formed on the top surface of the protrusion 22, and both ends of the groove 24 extend to the opposite sides of the protrusion 22. A fixing hole 25 is formed on the bottom wall of the groove 24. During installation, the side of the spring is inserted into the groove for pre-positioning, and then the spring can be fixed by screws or the like engaging with the fixing hole.

[0024] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
