蜂鸣器中的发音膜片是用IJ50软磁合金薄带制成的。除了要求材料具有一定的磁性能外,对硬度和厚度一致性及板型也都有很高要求。为此开展了一系列工艺研究试验,以寻求最佳生产工艺,稳定产品质量。最终达到了预期目的。
The diaphragm in the buzzer is made of IJ50 soft magnetic alloy ribbon. In addition to the material has a certain magnetic properties, the consistency of hardness and thickness and shape also have high requirements. To this end launched a series of process research trials to find the best production technology and stability of product quality. Eventually reached the desired goal.
