Description

Technical Field

[0001] This utility model relates to the technical field of speaker component assembly equipment, and in particular to a speaker diaphragm assembly and fixing device. Background Technology

[0002] The speaker diaphragm is the core component for sound production in a speaker, and its assembly precision directly affects the speaker's acoustic performance. During diaphragm assembly, it must be stably pressed and fixed to ensure precise and unbiased contact between the diaphragm and the speaker housing. Existing diaphragm assembly and fixing devices are mostly single-specification designs, only suitable for diaphragms of a certain diameter. When assembling diaphragms of different diameters is required, the entire pressing and fixing assembly must be replaced, increasing equipment costs, interrupting the assembly process, and reducing production efficiency. While some adjustable devices can achieve diameter adaptation within a certain range, the adjustment process requires manual adjustment of each pressing component individually, resulting in low adjustment efficiency and poor synchronization of components. This can easily cause uneven stress on the diaphragm, leading to assembly deformation or positional deviation, affecting product quality.

[0003] To address the aforementioned issues, this invention proposes a speaker diaphragm assembly and fixing device. By incorporating components with adjustable radial positions and a synchronous control structure, it enables rapid, synchronous adjustment and stable clamping of diaphragms of different diameters, thereby improving assembly efficiency and compatibility.

[0004] Therefore, the existing technology of speaker component assembly equipment needs further improvement. Utility Model Content

[0005] The purpose of this invention is to provide a speaker diaphragm assembly and fixing device, and a device that can flexibly adjust the auxiliary pressing and fixing during the assembly of speaker diaphragms of different diameters, so as to achieve efficient and precise assembly of diaphragms of various specifications.

[0006] To achieve the above objectives, the present invention adopts the following solution:

A pressing shaft is provided at the lower end of the radially adjustable components, and a symmetrical flipping flexible pressing plate assembly is provided at the lower end of the pressing shaft. A synchronous opening and closing control assembly for synchronously controlling the movement of the plurality of radially adjustable components is provided on the lifting and fixing assembly.

[0008] Furthermore, the lifting and fixing assembly includes a connecting shaft for connecting the lifting assembly, and a clamping and fixing plate is provided at the lower end of the connecting shaft.

[0009] Furthermore, the radial adjustment assembly includes a radial guide groove disposed on the clamping and fixing plate, and a sliding member is movably disposed within the radial guide groove.

[0010] Furthermore, the symmetrical flipping flexible pressing assembly includes a gear plate disposed at the lower end of the pressing shaft, a gear seat disposed on each side of the gear plate, a rotating gear rotatably disposed on the gear seat, the two rotating gears meshing and transmitting power to each other, and an arc-shaped pressing sheet disposed on the lower surface of the rotating gear.

[0011] Furthermore, the synchronous opening and closing control component includes an annular groove disposed on the outer circumference of the connecting shaft, a rotating ring rotatably disposed within the annular groove, a plurality of inclined guide grooves disposed on the rotating ring, a drive shaft disposed on the upper surface of the sliding member, and the drive shaft being movably installed in a corresponding inclined guide groove.

[0012] Furthermore, the connecting shaft is provided with a locking nut assembly for pressing the rotation angle of the rotating ring.
