Beschreibung
Zusammenfassung:	The invention discloses a preparation method and application of an ultrathin wood diaphragm with excellent acoustic characteristics and dimensional stability, wood is immersed in a sulfamic acid/urea/lactic acid ternary eutectic system, microwave treatment is carried out at a specific temperature, then deionized water is used for washing, and then hot pressing is carried out to obtain the ultrathin wood diaphragm. The prepared wood vibrating diaphragm shows excellent acoustic characteristics and dimensional stability. 本发明公开了一种具有优异声学特性和尺寸稳定性的超薄木质振膜的制备方法及应用，将木材浸入氨基磺酸/尿素/乳酸三元低共熔体系中，在特定温度下微波处理，再用去离子水洗涤，然后热压得到超薄木质振膜，所制备的木质振膜表现出优异的声学特性和尺寸稳定性。
