A speaker is provided to transmit uniformly vibration to top and bottom directions by forming a neck of a diaphragm with an upper unit and a lower unit. An upper member(25) fixed to a voice coil(16) is formed at a neck part(23) of a diaphragm(22). A receiving groove(23a) is formed between the diaphragm and the upper member. An adhesive is inserted into the receiving groove. The adhesive is moved from the receiving groove to a gap between a voice coil and the neck part while an edge is pressed to the receiving groove. A center cap(18), the diaphragm, and the voice coil are fixed mutually by moving the adhesive from the receiving groove to the gap between the voice coil and the neck part. |
