Metal vibration film forming equipment

Abstract

The invention relates to metal vibration film forming equipment, which comprises a machine seat, a forming mechanism and a control mechanism, wherein the forming mechanism comprises a vibration film forming mold and a driving assembly, wherein the control mechanism comprises an upper mold cylinder pushing control circuit, a lower mold cylinder pushing control circuit and an air pressure control circuit, the upper mold cylinder pushing control circuit is used for controlling the upper mold cylinder pushing action, the lower mold cylinder pushing control circuit is used for controlling the lower mold cylinder pushing action, and the air pressure control circuit is used for controlling the air blowing of an air pressure source. The metal vibration film forming equipment is specially used for metal vibration film forming, in addition, the energy consumption is low, and the forming quality is good.

Description

technical field [0001] The invention relates to a diaphragm forming device, in particular to a metal diaphragm forming device. Background technique [0002] Loudspeaker is a common electro-acoustic transducer device, which is widely used in electronic equipment in daily life and work. The diaphragm is an important component of the sound of the speaker. The sound of the speaker is completely derived from the movement mode of the diaphragm, and determines the timbre and sound quality of the speaker. As people's requirements for speaker sound effects are getting higher and higher, the requirements for diaphragm quality are also getting higher and higher. The material of the diaphragm has experienced development from paper, plastic, metal, composite materials, etc. Due to the high technical difficulty in preparing a metal diaphragm that meets the requirements, the cost of the metal diaphragm dome unit is relatively expensive, and the metal diaphragm dome is used. Most of the u...

AI Technical Summary

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
