Problems solved by technology
In actual production, this kind of molding equipment has complex structure, high power consumption, low efficiency, and difficult to control the molding process conditions. The size, density, and shape of the produced diaphragm cannot be guaranteed, which affects the quality of the speaker.
In particular, the softening of the metal diaphragm requires a higher temperature, and the metal diaphragm is prone to thermal expansion and contraction during the process of heating and cooling, which will affect the quality of the metal diaphragm. Therefore, this patented technology is not applicable to Metal Diaphragm Forming

Description
technical field [0001] The invention relates to a vibrating film forming device, in particular to a metal vibrating film forming device. Background technique [0002] Speaker is a common electro-acoustic transducer, which is widely used in electronic equipment in daily life and work. The diaphragm is an important component of the speaker's sound. The sound of the speaker is completely derived from the movement mode of the diaphragm, and determines the sound and sound quality of the speaker. As people have higher and higher requirements for the sound effect of speakers, the requirements for the quality of the diaphragm are also higher and higher. The material of the diaphragm has undergone the development of paper, plastic, metal, composite materials, etc. Due to the high technical difficulty in preparing the required metal diaphragm, the cost of the metal diaphragm dome unit is relatively expensive, and the metal diaphragm dome is used. Most of the units are high-end speak...
