The speaker housing(102) is coupled with one surface of the antenna housing(101) in a state of being protruded. The hinge device(200) rotatably couples the speaker housing(102) with the antenna housing(101). The hinge device(200) rotates in the center of a rotary axis extended in a direction of being protruded from one surface of the antenna housing(101). The cover(115) is attached to the other surface of the antenna housing(101). The switch button(119) is attached to the other surface of the antenna housing(101).
