Method of manufacturing speaker with diaphragm arrangement |
摘要 |
A manufacturing method of a diaphragm arrangement for a speaker includes the steps of mold injecting polypropylene material as a raw material to form a middle foaming layer, and sandwiching the middle foaming layer between first and second layers to form a flat speaker diaphragm. The flat speaker diaphragm is arranged to mount at an opening of a supporting frame of a speaker for receiving a vibration force generated from an electromagnetic provider in the supporting frame. |

1. A manufacturing method of a flat planar diaphragm arrangement for a speaker, comprising the steps of:
(a) mold injecting a raw material to form a middle foaming layer, wherein said raw material is polypropylene material and said middle foaming layer has a planar configuration; (b) applying two adhering films onto two opposed sides of said middle foaming layer respectively; and (c) forming first and second layers, and adhering and sandwiching said middle foaming layer between said first and second layers to form a flat speaker diaphragm in a planar configuration, wherein said first and second layers are made of different materials of said middle foaming layer, and a thickness of said middle foaming layer is larger than a thickness of each of said first and second layers. |
