PURPOSE: A vibration motor integrated with a speaker and a mobile communication terminal using the vibration motor are provided to secure an occupied space within the mobile communication terminal, add the other service function by attaching the other function element to the secured space, and reduce the whole size of the mobile communication terminal. CONSTITUTION: A rim is attached to an outer wall of a speaker(21) in a round shape and forms a main body of a vibration motor(22). A coil(23) is wound on the outer part of the rim to be separated from the speaker(21) so as to form an electric field at the rim by a current applied from an electric equipment mounting the speaker(21). A semicircular magnet is mounted in the rim and rotates in the rim by the electric field unbalancedly for vibrating the rim. Oil is inserted into the rim to be contacted with the magnet so as to lubricate the magnet and cool heat generated when the magnet rotates.
