Analysis and Research of GMM Bone Conduction Pronunciation Vibrator Output Characteristics

Abstract:

A new bone conduction pronunciation vibrator with a bow-type structure is proposed based on the excellent characteristics of the giant magnetostrictive material (GMM); The theoretical derivation of displacement amplification ratio is carried on based on the elastic mechanics theory; And the theoretical result is simulated in magnetic-structure coupling field through ANSYS; Eventually the actual output displacement is measured using some equipment such as the laser displacement sensor. And the reliability of the theoretical derivation is vertified by the simulation and the test. All the work done in the paper provides reference and basis for the structure parameters design and optimization of the pronunciation vibrator.
