| titleOfInvention | Laser 3D three-dimensional horn drum paper carcass composite basin, dust cover and production method |
| abstract | The invention relates to the technical field of drum paper carcasses, and discloses a laser D three-dimensional horn drum paper carcass composite basin and a dust cover, including a drum basin, the drum basin is in the shape of a horn, and a magnetic circuit system is fixedly installed at the bottom of the drum basin , The magnetic circuit system is provided with a dust cover, a laser 3D three-dimensional horn drum paper carcass composite basin, and a dust cover. When the annular block and the annular connecting block are screwed together, the position of the semicircular groove will correspond to the rectangular groove. , at this time, the snapping ball and the elastic wave will lose the pressing force of the inner wall of the annular block on it, and then the elastic wave will rebound and push the rectangular groove, so that the snapping ball will be stuck inside the semicircular groove to achieve the effect of secondary fixation. It avoids the dust cover falling off due to the vibration generated by the audio when the music is played later. |
