Title: Diaphragm for speaker
Inventor: TAKEUCHI HIROSHI
IPC: B32B3/12
Filed: 1981-03-13
Abstract: PURPOSE:To improve the efficiency of a speaker by pasting a honeycomb core and a skin material composed of Mg-Li alloy to constitute a diaphragm. CONSTITUTION:A skin material is pasted to a single or both sides of a core 2 constituted by gathering unit cells with adherent 3 to produce a diaphragm for a speaker. Mg-Li alloy mainly composed of Mg and Li is used as the skin material. When the contents of Li are >=5.7wt% in the Mg-Li alloy, plastic deformation workability is made easy. The density of alloy is reduced by increasing the contents of Li and reaches a half of Al weight. However, since the corrosion resistance is reduced by the increment of Li, it is desirable to fix the contents of Li in the Mg-Li alloy on 5.7-2.0wt%. The diaphragm produced in this procedure has sufficient strength and can improve the efficiency of a speaker without improvement of a driving system.
