Embodiment Construction

[0006] The key to the titanium sound film used in loudspeakers is to use titanium foil. Specifically, it is made according to the following process: the titanium strip or foil is processed by a multi-roller foil rolling mill and rolled more than twice to a thickness of 0.02mm-0.1mm, annealed at 530--640 degrees in a vacuum annealing furnace, and kept for 2-- After 4 hours, the degree of vacuum reached more than 10 to the negative 5th power, and the oven was released at room temperature. Take it out to be the finished product.

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of audio equipment, in particular to the improvement of the sound membrane in the loudspeaker. Background technique [0002] For a long time, high-quality titanium foil has been dependent on imports. The sound film in the loudspeaker is a key component of sound generation. Titanium sound film is one of them. All have high demands. Its performance directly determines the quality and sound effect of the loudspeaker. None of the existing domestic products can compare with imported products. Contents of the invention [0003] The invention aims to provide a titanium sound film for a loudspeaker to achieve the purpose of improving the sound quality of the loudspeaker. [0004] Specifically, the titanium sound film for the loudspeaker is made of titanium foil according to the following process: the titanium strip is processed by a multi-roll foil rolling mill or the foil is rolled to a thickness of 0.02mm-0.1...
