四、晶体拾音器的设计晶体拾音器的设计首先应从临界负载重量开始,即计算一下采取那种振动方式可使唱针尖的临界压力(即维持唱针尖与音纹保持接触的最低压力)最小.目前采取的振动方式有:伸张或压缩、弯曲、扭曲三种(图8).从弹性理论可知:各向同性固体的弹性常数,杨氏 Crystal Pickup Design Crystal pickup design should first start with the critical load weight, that is calculated to take that kind of vibration can make the critical pressure of singing tip (that is, to maintain the minimum pressure of the stylus tip and voiceprint to keep in contact) minimum. The vibration modes are as follows: stretching or compressing, bending and twisting (Figure 8). From the theory of elasticity, the elastic constants of isotropic solid, Young’s
