The present invention provides a speaker device in which assembly is easy,
and which has high sensitivity and low distortion. The speaker device
comprises a frame member, a piezoelectric element to which a sound signal
is applied, a diaphragm attached to the piezoelectric element, a coil for
boosting the sound signal, and a damper attached to the piezoelectric
element in the opposite side face to the diaphragm to elastically support
the piezoelectric element. The coil is wound with respect to the frame
member, and the damper is attached on the frame member.
