INTERNAL COMBINATION STRUCTURE OF MICRO SPEAKER FOR TELECOMMUNICATION TERMINAL

摘要

PURPOSE: An internal combination structure of a micro speaker for a telecommunication terminal is provided, which can increase an electromagnetic force by increasing a magnetic flux and preventing a leakage of a magnetic force, and can reduce the inside space consumption of the terminal. CONSTITUTION: An upper top plate(20) and a bottom top plate(20') are installed separately on an inner wheel magnet(30) and an outer wheel magnet(30'). The upper top plate is separated into an inner wheel top plate(21) installed on the inner wheel magnet and an outer wheel top plate(21') installed on the outer wheel magnet, and the inner wheel top plate and the outer wheel top plate are installed on the inner wheel magnet and the outer wheel magnet individually. The bottom top plate is installed below the inner wheel magnet and the outer wheel magnet.
