Abstract

PURPOSE:To prevent the generation of abnormal sound, by providing holes under the yoke constituting the magnetic circuit, inserting the tool holding the voice coil at the center of the magnetic pole space from these holes, and positioning the coil along this tool. CONSTITUTION:A plurality of holes 9 are placed under the yoke 4 constituting the magnetic circuit, the assembling tool 8 is inserted through the holes 9 from the back of the magnetic circuit, the voice coil 7 is inserted to the external circumference of the assembling tool 8, and the voice coil 7 is held at the center of magnetic pole. Further, the spider 6 is put in the voice coil 7 and fixed to the frame 1 and the voice coil 7, and after that, the diaphragm 5 is covered on the voice coil 7, it is fixed and bonded with the frame 1 and the voice coil 7, the assembling tool 8 is picked up after the adhesives is dried, thereby preventing the voice coil 7 from being removed from the center of magnetic pole, which is cuased at the assembling of the diaphragm 5, and the occurrence of abnormal tone can be avoided.
