A cylinder-shaped speaker casing(131) is injection-molded with plastics to set the speaker(132) while rotating. A wire(135) supplies a voice signal to the speaker(132). The speaker(132) consists of as follows. A diaphragm unit(132c) includes a diaphragm to generate the sound wave. A coil unit(132b) generates a vibration on the diaphragm.
