SPEAKER DEVICE OF A PORTABLE TERMINAL, SPECIALLY IN CONNECTION WITH SMOOTHLY TRANSMITTING A SOUND WAVE FROM A SPEAKER, SO THAT A USE CAN CLEARLY LISTEN TO A VOICE OF OTHER PARTY WITHOUT DISTORTION

摘要

PURPOSE: A speaker device of a portable terminal is provided to further comprise a speaker casing which is rotated to control a sound wave transmitting direction of a speaker, thereby smoothly transmitting a sound wave from the speaker in a call waiting state while directly controlling a speaker direction to enable a user to clearly listen to a voice of other party without distortion. CONSTITUTION: A speaker device(130) comprises as follows. A speaker(132) is embedded in a folder casing(122), and converts an electrical signal into a high-quality sound wave. 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. Fixing units(132a) are protruded from both side ends of the speaker(132) to be fixed to the speaker casing(131).
