MOVING COIL TYPE DYNAMIC ARMATURE SPEAKER

摘要

The present invention relates to a moving coil type dynamic armature speaker capable of: decreasing distortions and increasing conversion efficiency by minimizing air resistance which is generated when a vibration plate vibrates by performing the vibration of the vibration plate in a way in which a vibration module is operated to rotate in a reciprocating motion based on a pivot; and easily forming a super slim shape. The moving coil type dynamic armature speaker by the present invention includes: a case which has an opening for sound propagation in one side; a vibration module which is installed to be operated by a pivot to rotate in a reciprocating motion in the case; and a magnetic circuit module which operates the vibration module in order to rotate in the reciprocating motion which operates the vibration module to rotate in the reciprocating motion. The vibration module includes: a vibration plate which is installed in the opening side, for sound propagation, of the case by having an edge as a medium; a coil unit which is connected with one end part of the vibration plate in a direction which is perpendicular to the longitudinal direction of the vibration plate; and a pivot which is installed to be adjacent to an end part of the vibration plate.
