Description

Technical Field

[0001] This utility model belongs to the field of loudspeaker diaphragm production technology, specifically relating to a cutting machine for loudspeaker diaphragm production. Background Technology

[0002] Speaker diaphragms can be made of paper or plastic. The reason a speaker produces sound is that the current signal output by the amplifier interacts with the magnet, which in turn drives the voice coil in the magnetic field to make a piston-like reciprocating motion. Since the diaphragm and the voice coil are glued together, the diaphragm vibrates back and forth, compressing air to generate sound waves, which are then transmitted to the ear, allowing people to hear the sound.

[0003] A search revealed a Chinese utility model patent application with Chinese patent publication number CN 221337137 U, which discloses a laser cutting and trimming device for a loudspeaker diaphragm. The device includes a frame, a crossbeam, a moving mechanism, a cutting mechanism, and a transmission mechanism. The frame is equipped with a transmission mechanism, the frame surface is equipped with a crossbeam, the crossbeam is equipped with a moving mechanism, the moving mechanism is equipped with a cutting mechanism, and the moving mechanism is equipped with a positioning mechanism. The positioning mechanism is a structure for manually adjusting the diameter of the ring. A partition is provided below the frame.

[0004] Regarding the aforementioned technologies, the cutting of the diaphragm is adjusted according to different needs during cutting, and it is impossible to limit and guide the cutting position based on the diaphragm cutting position, resulting in inaccurate cutting positioning. Therefore, it is urgent to design a cutting machine for loudspeaker diaphragm production to solve these problems. Utility Model Content
