PURPOSE: A speaker device is provided to draw interest of users by increasing the volume of a sound output part by a volume control part. CONSTITUTION: A speaker device (100) comprises a main body, a sound output part (400), and a volume control part (500). The main body comprises first and second rotary members (200, 300) having one ends rotatably combined by a hinge shaft. The sound output part is mounted at the first rotary member or the second rotary member and outputs a sound corresponding to a sound signal received through a signal input terminal mounted at the main body. The volume control part is mounted at a signal transfer system connected from the signal input terminal to the volume output part. The volume control part increases the volume of the sound output part as the other ends of the first and second rotary members being separated by controlling the volume of the sound outputting part according to the rotation angle of the hinge shaft. |
