A multi-function vibration micro-speaker according to the present invention includes a fixing part for providing an inner space having a predetermined size; at least one permanent magnet disposed at the inner space of the fixing part to generate magnetic force; a coil disposed to face the permanent magnet to generate electromagnetic force by interworking with the permanent magnet; a vibration part integrally coupled to the coil and including a support member disposed at a lower side of the coil; an elastic member coupled to the fixing part and the vibration part to provide elastic force; and a power supply coupled to the vibration part, disposed on a lower end of the permanent magnet to prevent a contact with the permanent magnet, and having a part formed in a spiral shape, wherein another permanent magnet surrounding the outside of an inner permanent magnet while being spaced apart therefrom by a predetermined interval is disposed and plural permanent magnets are provided such that the magnetic force is increased, A coil is disposed between the permanent magnets to generate strong vibration force such that the coil may be operated by a micro signal, and a ferromagnetic substance surrounds the outside of the micro-speaker to block leakage flux generated from the permanent magnet so that the magnetic flux does not influence an electronic device or a human body. |
