The invention discloses an alloy titanium foil for manufacturing high-quality voice diaphragms. The alloy titanium foil is composed of the following raw materials in parts by weight: 180-200 parts oftitanium powder, 10-15 parts of tin powder, 5-10 parts of nano titanium dioxide, 5-10 parts of indium powder and 8-12 parts of molybdenum powder. The alloy titanium foil for manufacturing the high-quality voice diaphragms disclosed by the invention has simple manufacturing procedures and can be made into high-quality voice diaphragms with thicknesses being 0.05mm or below according to needs. The voice diaphragms manufactured by the alloy titanium foil disclosed by the invention has relatively high rated power, the timbre of alto voice and high pitch parts is plump and excellent, and the degreeof distortion is very low. 本发明公开了种用于制作高品质音膜的合金钛箔，由如下重量份的原料组成：钛粉180-200份，锡粉10-15份，纳米二氧化钛5-10份，铟粉5-10份，钼粉8-12份。本发明的用于制作高品质音膜的合金钛箔的加工工序简单，可以根据需要制成厚度在0.05mm以下的高品质音膜。用本发明的合金钛箔制成的音膜的额定功率较高，中音与高音部分音色饱满出色，失真度很低。
