PROBLEM TO BE SOLVED: To provide a speaker unit in which bending stress incident to vibration is not applied to a specific portion of a feeder (tinselled wire) for supplying a drive signal to a voice coil. SOLUTION: A drive cone 11 and a diaphragm 14 are driven integrally by a voice coil 6 arranged movably in a magnetic gap 5. Peripheral edges of the drive cone 11 and the diaphragm 14 are supported on the frame 12 through edge portions 13 and 15, respectively. A part of a feeder for supplying a drive signal to the voice coil 6 is arranged in the edge portion 13 supporting the drive cone 11 while being embedded as shown by a code 21a. With such an arrangement, the tinselled wire 21a follows up deformation of the edge portion 13 in the drive cone 11 according to vibration of the diaphragm 14 thus preventing bending stress incident to vibration from being applied to a part of the tinselled wire 21a.
