Abstract: A motor-integrated acoustic output unit, comprising: a speaker frame of which one surface and the other surface are open; a diaphragm covering an opening part of the one surface of the speaker frame and being coupled to the speaker frame; a yoke covering the other surface of the speaker frame; a motor unit which is coupled to the yoke and which has at least a portion positioned inside the speaker frame; a voice coil positioned on the circumference of the motor unit, vibrating in the directions of the one surface and the other surface, and causing the diaphragm to vibrate; and an outer magnet positioned outside the voice coil, wherein the motor unit comprises: a motor frame coupled to the yoke; a motor coil fixed to the motor frame; an elastic part of which one side is coupled to the motor frame; and a motor magnet coupled to the other side of the elastic part, implements speaker, receiver, and motor functions with one module so as to reduce a mounting space, thereby reducing the number of components such that a manufacturing process is simplified and manufacturing costs can be reduced.
