The conventional hinge device has a structure in which two hinge modules are mounted symmetrically. According to this structure, the hinge device has a configuration that is opened and closed while rotating from the bottom to the top with the rotation center axis. In addition, it was a configuration having a mechanism capable of electrically connecting the speaker installed in the flip cover to the printed circuit board of the main body. At this time, the two wires drawn from the speaker were directed toward the main body through the hinge knuckle via the neck of each flip cover.

However, in general, the basic configuration of the mobile phone has a configuration in which the antenna device is located in the uppermost corner of the main body, the LCD module is located below the antenna device, and then the keypad and the microphone are mounted.

In the flip-up type mobile phone, when the flip cover is opened, an interference phenomenon occurs between the speaker mounted on the flip cover and the antenna unit, thereby deteriorating antenna characteristics. That is, when the flip cover is opened, the interference phenomenon with the speaker wire located at a close distance to the antenna becomes very severe and exists at a distance that may affect the antenna device, thereby causing a problem of degrading the performance of the antenna device. .

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to flip the interference phenomenon between the antenna of the speaker wire and the speaker installed in the flip cover, the flip cover type opening and closing operation in the flip-up mobile phone, By minimizing, it provides a speaker wire mounting structure with improved antenna characteristics.

Still another object of the present invention is to provide a wire mounting structure of a speaker, which is improved in assembly from the viewpoint of the assembly industry.

In order to achieve the above objects, the present invention includes a main body including an antenna device and an LCD module and the like, and a speaker to which both wires are drawn and connected to the main body, and a neck through which both wires pass respectively extends. In the flip-up type mobile phone comprising a flip cover having a knuckle formed at the end of the neck, and a hinge device for mechanically connecting the body and the flip cover,

When the flip cover mechanically connected by the hinge device performs the opening and closing operation about the rotation axis in the main body, in order to minimize the interference between the antenna device installed in the main body and the speaker installed in the flip cover.

Both wires provided in the flip cover are electrically connected to the main body via a hole formed in a neck far from the antenna device.
