摘要 |
The present invention relates to a bone conduction speaker using a vibrating plate. The bone conduction speaker using a vibrating plate according to the present invention is characterized in that the bone conducting speaker comprises: a body having a shape of a cylinder with an upper portion and a lower portion opened; a mastoid having a lower diameter and a upper diameter, wherein the lower diameter is relatively smaller than the upper diameter; a vibrating late being inserted to a lower portion of the mastoid to close an upper opening portion of the body, wherein the vibrating plate is made of an elastic material; an auxiliary vibrating plate being inserted to a lower portion of the mastoid under the vibrating plate which is inserted to the mastoid; a vibrating coil being attached on a lower side of the auxiliary vibrating plate; a speaker plate being fixed at an inner central portion of the body having the shape of the cylinder, wherein a central hole is provided at the central portion of the speaker plate; a ring type magnet being fixed on the speaker plate; a yoke, wherein an edge portion of the yoke is fixed on the ring type magnet and a central portion of the yoke has a protrusion which protrudes in the inside direction of the central hole of the speaker plate; an acoustic vibrating plate being fixed at a lower portion of the body to close a lower plane of the body; an acoustic coil being fixed on the acoustic vibrating plate and being inserted between the ring type magnet and the yoke; and an electrical signal input unit for applying a predetermined electrical signal to at least one of the vibrating coil and acoustic coil. |
