Abstract
Official abstract text for this publication.
Provided is an inexpensive speaker diaphragm which can suppress inter-layer peeling. A speaker diaphragm includes a first diaphragm layer and a second diaphragm layer which are respectively configured by sheet-forming bodies of materials and stacked to each other, and the first diaphragm layer and the second diaphragm layer are integrally formed in a boundary portion.
First claim
Opening claim text (preview).
1 . A speaker diaphragm comprising: a plurality of sheet-forming bodies configured to be stacked, wherein two sheet-forming bodies adjacent to each other are integrated, and these integrated two sheet-forming bodies are peelable to be two sheet-forming bodies, and wherein an entangled portion is provided over the entire boundary between the adjacent two sheet-forming bodies. 2 . The speaker diaphragm according to claim 1 , wherein the entangled portion is formed by entangling fiber of one sheet-forming body permeating another sheet-forming body with fiber of the another sheet-forming body. 3 . The speaker diaphragm according to claim 2 , wherein a thickness of the entangled portion is smaller than a thickness of one sheet-forming body of the two sheet-forming bodies. 4 . The speaker diaphragm according to claim 2 , wherein a peeling strength is provided between the two sheet-forming bodies. 5 . The speaker diaphragm according to claim 4 , wherein a space of the another sheet-forming body is smaller than a space of the one sheet-forming body. 6 . The speaker diaphragm according to claim 5 , wherein a direction of the fiber in the boundary other than the entangled portion is a direction along the boundary, and a direction of the fiber in the entangled portion is a direction from the another sheet-forming body to the one sheet-forming body. 7 . The speaker diaphragm according to claim 6 , wherein a Young's modulus of the another sheet-forming body is larger than a Young's modulus of the one sheet-forming body. 8 . The speaker diaphragm according to claim 6 , wherein the one sheet-forming body is a surface layer in the plurality of sheet-forming bodies, and the one sheet-forming body has a uniform thickness over the entire area. 9 . The speaker diaphragm according to claim 8 , wherein the another sheet-forming body adjacent to the one sheet-forming body has a uniform thickness over the entire area.
