A hinge device of a flip type mobile telephone including a body and a flip cover with a speaker mounted thereon. In the hinge device, a hinge assembly includes a spring connector pin; a hinge shaft having at least one open end, a pair of opposite protrusions, a pair of opposite indents, and a cylindrical inner wall into which the connector pin is pressed, the shaft being movable along a rotation axis; a hinge housing having at least one open end into which the hinge shaft is inserted; guide means for enabling the hinge shaft to move rectilinearly in the hinge housing; and securing means for preventing separation of the hinge shaft from the hinge housing. The hinge device further includes a coupling member having a pair of opposite protrusions and a pair of opposite indents, for keeping in sliding surface contact with the hinge shaft; and conducting means interposed between the hinge assembly and the coupling member, for electrically connecting the speaker to a printed circuit board housed within the body. In this manner, the hinge device can connect the speaker mounted on the flip cover to the body, thus contributing to miniaturization of the mobile telephone.
