The present invention provides a titanium sound film for loudspeaker. The invention is characterized in that the titanium foil is manufactured through the following processes: processing titanium strip material through a multi-roller foil mill or executing more than two times of rolling to a thickness of 0.02mm-0.1mm, cleaning for degreasing after aligning and leveling, annealing through a vacuum annealing oven in the temperature of 530-640 DEG C, keeping the temperature for 2-4 hours, facilitating the vacuum degree to above 10, and taking the titanium sound film out from the furnace. The finished product is obtained after taking out. The acoustic quality of titanium sound film according to the invention is excellent. The punching capability, plasticity and material hardness can totally obtain the using requirement.
