Abstract

PURPOSE:To make easy the coaxial arrangement of diaphragms, by constituting the magnetic circuit with polygonal arrangement of the fields in straight line and locating each magnetic circuit corresponding to each diaphragm. CONSTITUTION:The diaphragms 1, 2, 3, 4 for low, medium, high and ultra-high tone parts are coaxially located in square shape. Each diaphragm is provided with the voice coil bobbins 11, 21, 31, 41 and voice coils 12, 22, 32, 42. The magnetic circuits 10, 20, 30, 40 are located corresponding to each voice coil. Since the magnetic circuits are formed in straight line, the space of inner circumference of external magnetic circuits can be increased, allowing the coaxial location of three or more diaphragms.
