VIBRATION MOTOR INTEGRATED WITH SPEAKER

摘要

PURPOSE: A vibration motor integrated with a speaker is provided to minimize the space occupied by the vibration motor and speaker, while allowing for a simplicity of production and assembly and increasing vibrations. CONSTITUTION: A speaker includes a magnet(18) and a plate(28) sequentially deposited on the center of a yoke(30) which is molded integrally with a housing(11); a dual dome-shaped vibration plate(26) attached to the upper surface of a vertical plate arranged in the outer periphery of the housing; and a coil(27) attached to the lower surface of the vibration plate in such a manner that the coil reaches the gap formed between the magnet and the yoke. A vibration motor includes one or more pairs of coils(16a,16b) which are wound in the directions opposite from each other and disposed in the space of the housing; a magnets(29) spaced apart from the coils and eccentrically coupled with a rotating shaft(20) coupled between a fixing groove(14) of the housing and a fixing hole(22) of a grill(12); and the grill coupled to an end of the housing in such a manner as to provide an internal space for rotation of the magnet and fix the rotating shaft.
