An electro-acoustic transducer includes a tone generator, a vibrator, and
a case. The tone generator includes a diaphragm, and a voice coil joined
to the diaphragm. The vibrator includes a magnetic circuit having a
magnetic gap at which the voice coil is positioned, and a suspension made
of metal and having a first end joined to the magnetic circuit to suspend
the magnetic circuit for allowing the magnetic circuit to vibrate. The
case is joined to a periphery of the diaphragm, and includes a metal
plate joined to a second end of the suspension. The metal plate is joined
to the suspensions reliably, hence allowing the electro-acoustic
transducer to be manufactured stably.
