Laser 3D horn cone paper carcass composite basin, dustproof cover and manufacturing method thereof

Abstract

The invention relates to the technical field of drum paper carcasses, and discloses a laser D stereo horn drum paper carcass composite basin and dustproof cover, which comprises a horn-shaped drum basin, the bottom of the drum basin is fixedly provided with a magnetic circuit system, and the magnetic circuit system is provided with a dustproof cover, a laser 3D stereo horn drum paper carcass composite basin and a dustproof cover. After the annular block is in threaded connection with the annular connecting block, the positions of the semicircular grooves correspond to those of the rectangular grooves, at the moment, the clamping balls and the elastic waves lose extrusion force on the clamping balls and the elastic waves from the inner wall of the annular block, then the elastic waves rebound, the rectangular grooves are pushed, the clamping balls are clamped into the semicircular grooves, and the secondary fixing effect is achieved; and therefore, the falling of the dustproof cover due to the vibration generated by the audio during the subsequent music playing process can be avoided.

Description

technical field [0001] The invention relates to the technical field of drum paper carcasses, in particular to a laser 3D three-dimensional trumpet drum carcass composite basin, a dustproof cover and a manufacturing method. Background technique [0002] In the past, the laser surface or bright surface of the carcass was obtained by electroplating, but because the electroplating area is not environmentally friendly, many processing factories are unwilling to accept electroplating, so the electroplated products are relatively relatively few. [0003] And the existing drum paper carcass has the problems of easy scratch and insufficient rigidity due to the reason of its technology. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the invention provides a laser 3D three-dimensional trumpet drum carcass composite basin, a dustproof cover and a manufacturing method. [0006] (2) Technical solution [0007] I...
