Rectangle Piezoelectric Bimorph Bone Conduction Auditory Device

Abstract:

Article Preview

The piezoelectric bone conduction auditory device (PBCAD) with a rectangular piezoelectric bimorph as a driving components was designed based on the principle of bone conduction(BC), the audio signal converted to a vibration signal stimulate the auditory nerve via the skull to create hearing. Finite element analysis of rectangular piezoelectric vibrator means to support and optimize the structure of the program and improve equipment sound effects in the regional auditory signals of low-frequency, the experiment of rectangular PBCAD chalks up the curve of structure parameters. Experimental studies show: rectangular piezoelectric BC unit can achieve better function of bone conduction auditory device (BCAD).
