Description

Technical Field

[0001] The utility model relates to a loudspeaker, in particular to a circular magnet single-sided damping loudspeaker. Background Art

[0002] Patent No.: 2023214511454 is a patent applied by the same applicant on June 8, 2023, with the patent name of: A damping loudspeaker. The damping structure in this application is a split type. The split type damping structure has the optimal damping effect on the strip-shaped magnetic circuit assembly, and can also improve the sound quality. However, when the split type damping is applied to the circular magnetic circuit assembly, the elastic pieces need to be mirror-mounted on both sides of the circular magnetic circuit assembly, and alignment is required for each installation. Once there is a deviation, it will affect the damping effect and sound quality. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to provide a circular magnet single-sided damping loudspeaker in order to solve the problems existing in the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a circular magnet single-sided damping loudspeaker, including a chassis and a magnetic circuit assembly, further including an elastic piece for single-sided damping. The central position of the elastic piece has an installation position for accommodating the magnetic circuit assembly. Both the installation position and the magnetic circuit assembly are circular. After the magnetic circuit assembly is arranged in the installation position, the magnetic circuit assembly and the elastic piece form a damping magnetic circuit, and the magnetic circuit assembly is connected to the chassis through the elastic piece.

[0005] Further, the magnetic circuit assembly is fixedly installed in the installation position.

[0006] Further, the magnetic circuit assembly is fixedly connected to the chassis through the elastic piece.

[0007] Further, the elastic piece is a metal sheet or a plastic sheet that is wide in the middle and narrow at both ends, and the elastic pieces on both sides of the installation position are of a hollow structure.

[0008] Further, both ends of the elastic piece are provided with positioning holes, and positioning posts for cooperating with the positioning holes are provided on the frame bodies on both sides of the chassis.

[0009] The beneficial effect of the utility model is that for the circular magnet single-sided damping loudspeaker of the utility model, a damping structure is designed for the circular magnetic circuit assembly. The elastic piece is a whole piece, with a hole opened in the central position, and then the magnetic circuit assembly is placed in the hole to achieve damping. The hole is the installation position mentioned in the text. During installation, the magnetic circuit assembly only needs to be inserted into the installation position and then fixed, with high production capacity and stable quality.

[0010] In summary, the utility model has the characteristics of simple structure, convenient installation and good sound quality. Description of the Drawings

[0020] The present utility model will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] As Figures 1 to 6 shown, a circular magnet single-sided damping loudspeaker includes a chassis 1, a magnetic circuit assembly 2, and a shrapnel 3. A circular mounting position is provided at the center of the shrapnel. The magnetic circuit assembly 2 is circular and is welded in the mounting position so that the magnetic circuit assembly 2 and the shrapnel 3 form an integral body, that is, a damping magnetic circuit is formed. The two ends of the shrapnel 3 rest on the chassis 1, and the shrapnel 3 and the chassis 1 are fixedly connected by laser welding.

[0022] The fixed installation of the magnetic circuit assembly 2 and the shrapnel 3 is to improve the service life. In the case of frequent vibrations, it is easy for the magnetic circuit assembly 2 and the shrapnel 3 to separate when using other fixing methods; similarly, the shrapnel 3 and the chassis 1 are also fixedly connected.

[0023] To improve the sensitivity and shock absorption effect of the shrapnel 3, the shrapnel 3 is a metal sheet or plastic sheet that is wider in the middle and narrower at both ends. The shrapnel 3 on both sides of the installation position is a hollow structure. Since it was mentioned above that the shrapnel 3 needs to be welded to the magnetic circuit component 2, the shrapnel 3 is usually made of metal material. Figure 2 and Figure 6 The difference lies in the different hollow patterns of the shrapnel 3, that is to say, the hollow structure does not limit the fixed pattern.

[0024] To improve the assembly efficiency and assembly accuracy, the end parts on both sides of the shrapnel 3 are provided with positioning holes 4, and the frame bodies on both sides of the speaker frame 1 are provided with positioning posts 5 that cooperate with the positioning holes 4 for positioning.

[0025] Figure 7 Figure is a comparison chart of the shell vibration displacement test between the present utility model and the existing speaker. In the figure, A is the existing speaker, and B is the present utility model. In the same area, the shell vibration of the present utility model is smaller, that is, the shock absorption effect is good.

[0026] What is described in the above specification is only the specific implementation manner of the present utility model. Various examples do not constitute a limitation to the essence of the present utility model. Those of ordinary skill in the art can make modifications or deformations to the previously described specific implementation manner after reading the specification without departing from the essence and scope of the utility model.
