PROBLEM TO BE SOLVED: To provide a "loudspeaker" with a plurality of dampers which are shaped to relax rolling of a voice coil bobbin and reduce a drive load of a diaphragm. SOLUTION: A plurality of the dampers 3a, 3b provided between a frame 1 and the diaphragm 2 gradually approach each other toward the diaphragm 2 and are located at the same span, so that the rectilinearity of the bobbin 7 in a vibrating direction is enhanced, the rolling is eliminated, and the load due to expansion/contraction of the dampers 3a, 3b is reduced to enhance the sensitivity of the loudspeaker thereby establishing the compatibility between the improvement of sound quality and a high output at a low sound frequency band.
