Description

Technical Field

[0001] The utility model belongs to the technical field of sound box drum paper, and in particular relates to a drum paper. Background Art

[0002] The drum paper is the main sound-producing component of the speaker, and the sound quality of the speaker is closely related to the drum paper.

[0003] The drum paper mainly consists of three parts: the body, the side and the gasket. The gasket is an auxiliary shaping component. Some different models of drum paper may not have this component, mainly based on customer requirements. Drum paper is divided into full paper drum paper, composite drum paper, Mylar drum paper, etc. according to different materials. Drum paper has three inherent characteristics: (1) light weight; (2) high elastic coefficient; (3) appropriate mechanical loss.

[0004] The drum paper is generally composed of three parts: the body, the hanging edge and the pressing edge. The body, the hanging edge and the pressing edge are sequentially bonded and connected during the drum paper production process to form a finished drum paper. Most common drum papers are composite drum papers, that is, the body and the edge are made of different materials, which are bonded together to form a complete drum paper. The common material of the body is paper, and there are also PP materials, aluminum bodies, copper bodies, etc. Common materials for the hanging edge are: foam, cloth, rubber, ESMA, TPU, etc. When the existing drum paper structure is glued, the glue is easy to flow out, and the glue outflow is easy to affect the hardness of the hanging edge. For this reason, an improved drum paper is designed. Utility Model Content
