|This paper describes the design process of a new electromagnetic transducer for implantable bone conduction hearing aids. The proposed electromagnetic transducer uses a dual coil and a magnetic circuit to generate high electromagnetic force. In addition, to satisfy the function as a transducer for implantable bone conduction hearing aids for treating conductive hearing loss, a vibrating membrane with a cantilever structure was used to generate high vibrational force in a specific frequency band. The vibrational membrane, which determines the frequency characteristics of the bone conduction transducer, was analyzed through mathematical modeling and finite element analysis was performed to derive the optimum structure. Based on the results of finite element analysis, transducers were fabricated through chemical etching process and CNC process. To verify the output characteristics of fabricated bone conduction transducer, the frequency response characteristics were measured under no-load condition and compared with the finite element analysis results. As a result, it is expected that the proposed transducer could be used as a transducer for implantable bone conduction hearing aid.
