应用于扬声器的泡沫金属适于作扬声器的材料把电能转换成声能,最主要的问题是如何做到逼真的能量转换。对扬声器来说,扬声器的振动膜最好是按活塞运动方式动作。扬声器的振动膜能否充分地作活塞运动关键的因素是振动膜的抗弯刚性。而振动膜的抗弯刚性一般要由振动膜的形状、边缘状态和振 Foam metal used in loudspeakers Suitable materials for loudspeakers Convert electrical energy into acoustic energy. The most important issue is how to achieve realistic energy conversion. For loudspeakers, the diaphragm of the loudspeaker is preferably actuated in a piston-like manner. Loudspeaker diaphragm can make adequate piston movement is the key factor in the bending stiffness of the diaphragm. The flexural rigidity of the diaphragm is generally determined by the shape, edge condition and vibration of the diaphragm
