发明名称 VIBRATION AND SOUND GENERATING DEVICE
摘要 PURPOSE: A vibration and sound generating device is provided to improve a vibration power by increasing the width of a spring at vibration function and prevent a spring from colliding with other parts although an over-voltage is applied. CONSTITUTION: A terminal plate(54) is attached on one side of a case(50). A magnetic generating part(52) generates a magnetic field and is embodied at a lower side of the case(50). A voice coil(56) is placed at a top of the magnetic generating part(52) and generates an electric field when a power is supplied. A vibration plate(58) generates a sound and is placed at a top of the voice coil(56). A spring(60) is placed between the magnetic generating part(52) and the case(50) and transfers the vibration from the vibration plate(58) into the exterior. An upper cover(62) and a lower cover(64) are mounted at upper and lower sides of the case(50), respectively.
