众所周知,铍在扬声器上早有应用,但由于它的成本及制造工艺的原因至今未得到广泛应用。现在,随着加工工艺水平的提高,已有铝铍合金的音膜,这一产品大大降低了成本;另一方面对铍的加工工艺也有了新的突破,使得铍有可能有更多的应用。因此,《电声技术》将“铍音膜”这篇文章推介给读者。 It is well known that beryllium has been used in loudspeakers for a long time, but it has not yet been widely used due to its cost and manufacturing process. Now, with the improvement of the level of processing technology, the sound film of aluminum beryllium alloy is already available, which greatly reduces the cost of the product; on the other hand, there has been a new breakthrough in beryllium processing technology, making beryllium likely to have more applications . Therefore, “electro-acoustic technology” will be “beryllium film” article to introduce readers.
