CONSTITUTION: According to the 2-way speaker unit, a high-pitched tone part(a) comprises a yoke(11) and a magnet(12) arranged in a center of a frame(10), and a magnet plate(13) and a diaphragm using a polyester film and a silk and a comb wafer selectively and a voice coil(15). A low-pitched tone part(b) comprises a yoke(21) and a magnet(22) arranged in the outer of the high-pitched tone part, and a magnet plate(23) and a diaphragm(24) using a polyester film and a voice coil(25). A penetration hole(30) is formed on a boundary of the high-pitched tone part and the low-pitched tone part, and a ring type frame(20) fixes the boundary of diaphragms of the high-pitched tone part and the low-pitched tone part. And conducting wires(16,26) are connected to the diaphragms and are connected to its own terminal through the penetration hole. In the diaphragm of the low-pitched tone part, a silk(24a) and a polyester film(24b) are arranged in the inside and in the outside respectively using the voice coil(25) as a boundary, and the inside and the outside parts are adhered in a body, and then the voice coil(25) is attached on its bottom.
