The present invention provides a mobile terminal comprising: a terminal body including an opening region through which a sound is outputted; and a waterproof speaker module arranged adjacently to the opening region and outputting the sound, wherein the waterproof speaker module includes a speaker module forming the sound, a housing accommodating the speaker module and including a sound hole through which the sound is outputted, and a cover part connected to the housing so as to form a separation space in which the sound is outputted by the sound hole, and moved by a water pressure at least that of a certain reference pressure so as to cover the sound hole, thereby preventing the inflow of water into the speaker module.

Mobile terminal

The mobile terminal is disclosed. The mobile terminal of the present invention may include a display unit, a body, a first signal unit, a second signal unit, and a signal connection module. The signal connection module may be disposed in a hole formed in the body to shield the hole. The signal connection module may electrically connect the first signal unit and the second signal unit. The first signal unit may be various circuit boards. The second signal unit may have a function of receiving an input or an antenna function.

A mobile terminal comprises: a case that has an insertion hole formed on a side surface thereof; a metal beam that includes a side metal covering the side surface of the case, and a connection bridge penetrating the insertion hole and extending towards the inside of the case from the side metal; a fixing device that is inserted into a fixing hole formed on the connection bridge so as to be fastened to the case; and a waterproof packing that is interposed between the side surface of the case and the side metal, and that has an opening part through which the connection bridge passes. As a result, water cannot get inside the terminal, and malfunctioning due to water permeation can be prevented thereby.

Provided is a mobile terminal comprising: a case comprising a button hole; a main board mounted within the case; a button module which is exposed to the outside through the button hole; a sealing rubber comprising an opening into which the button module is inserted; a first waterproof tape in the form of a closed curve, which joins the sealing rubber and the button module; and a second waterproof tape in the form of a closed curve, which joins the sealing rubber and the case. The button module comprises: a fingerprint recognition module for recognizing a user's fingerprint when touched by a user's finger; a switch for generating a signal when pressed; and a flexible board comprising a mounting portion for mounting the fingerprint recognition module and the switch therein, a contact portion contacting the main board, and a connection portion for connecting the mounting portion and the contact portion.

The durability of a mobile terminal can be improved by improving the heat-dissipating performance thereof, the mobile terminal comprising an inner space and having a camera hole formed on the rear surface thereof; a substrate located in the inner space and having an electric element mounted thereon; a camera module including a lens part and mounted at a location corresponding to the camera hole; a deco frame, which includes a lens hole for exposing a lens part of the camera module and a heat-dissipating hole formed on the circumference of the lens hole, and is inserted into the camera hole; and a heat-dissipating sheet located in the inner space and including a heat-absorbing part coming in contact with the electric element, a heat-dissipating part located on the inner side of the deco frame and covering the heat-dissipating hole, and a heat transfer part connecting the heat absorbing part and the heat-dissipating part.

A mobile terminal is disclosed. The mobile terminal includes a body; a body hole formed in the body, the body hole communicating an inside and an outside of the body; and a waterproof unit positioned and movable in the body hole, the waterproof unit including: a rod extended in a communicating direction of the body hole; a stopper connected to an end of the rod, a portion of the stopper having a inclined shape with respect to a longitudinal direction of the rod; and a packing ring surrounding the rod, the packing ring sealing the body hole.
