The giant magnetostrictive material (GMM) is an ideal functional material for low frequency transducer. The basic properties of GMM are introduced and the magnetostrictive phenomenon is explained. The material is compared with traditional magnetostrictive material and electromagnetism material, piezoelectric material which are both widely applied in bone-conduction hearing device. The present application status of bone-conduction hearing device is overviewed. Particularly the design of the GMM pronunciation vibrator is introduced and the future that bone-conduction hearing device with GMM will be applied in military communication is also looked far ahead.
