Abstract
A high stability loudspeaker has a yoke with a plurality of vents installed therein. The yoke is combined to a bottom of a frame of the loudspeaker. A magnet is placed in the yoke. A washer is arranged above the magnet. A periphery of the magnet is surrounded by a voice coil. A coil winding surrounds the voice coil. A combining portion is formed at a periphery of the yoke. The combining portion serves to be combined with a surround connected to a bottom of end of the voice coil. The voice coils is vertically installed in a gap between the portions of the yoke. The top of the voice coil is connected to another surround. Thereby, vibration of the voice coil is confined at the two ends. As a result, the gap between portions of the yoke structure into which the voice coil extends between portions of the yoke is reduced and therefore, the sensitivity of the loudspeaker is increased and the distortion is decreased.
