Title:
BONE CONDUCTION VIBRATION TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/2020/096356
Kind Code:
A1
Abstract:
The present invention relates to the structure of a magnetic circuit of a bone conduction vibration transducer capable of maximizing driving force. The purpose of the present invention is to divide a winding into two and separate and place the same number of winding coils in two narrower pores to reduce a gap between the pores, thereby maximizing magnetic flux interlinked to the coils and enhancing electromagnetic force.
