초록

Recently, hearing loss patients have been increasing to excessive use of various multimedia devices. One of the hearing rehabilitation systems, bone conduction hearing aid can be used to conductive deafness patients efficiently. However, the conventional bone conduction hearing systems has some problems such as skin diseases, repulsion of patients, and vibration power reduction by skin damping. In this paper, to overcome the conventional problems, we proposed power improvement method by curved beam diaphragm. The proposed method is skin attachment system which is non-implantable, and then the power of transducer is improved by the proposed method. In order to improve the vibration power of diaphragm, variable that has correlation with displacement are extracted, the diaphragm designed by extracted variable. To verify efficient of the proposed method, experiment conducted by finite element analysis. As a result of, the proposed method confirmed improved power to compare with the conventional method and proposed method.
