A multi-functional vibrating microspeaker is provided to offer a variety of application services, such as tactile vibrations, a bone-conduction function, and an attached speaker when a vibration coil unit is attached downward at an upper housing. A multi-functional microspeaker includes housing, an elastic supporting unit(11), a magnet supporting unit(12), a center magnet(14) and an outer ring magnet(15), and a vibration coil unit(16). The elastic supporting unit is disposed beneath the magnet supporting unit and includes at least one elastic bridge. The elastic bridge is concentrically assembled with the magnet supporting unit to prevent eccentricity of the elastic supporting unit. The magnet supporting unit is concentrically assembled with the elastic supporting member. The magnet supporter has an enough size to be spaced apart from a lateral housing. The central magnet and the outer ring magnet are attached to the magnet supporting unit. The outer ring surrounds the central magnet with a space therebetween. The vibration coil unit is inserted into a space formed between the center magnet and the outer ring magnet. |
