For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from one another, or may be disposed integrally with one another, and may be disposed on different surfaces, respectively.

When the display unit 151 and a sensor for detecting a touch operation (hereinafter, referred to as a “touch sensor”) form a mutual layer structure (hereinafter referred to as a “touch screen”), the display unit 151 may be used in addition to an output device. Can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched.

In addition, a proximity sensor may be disposed in the inner region of the mobile terminal or by the touch screen, which is covered by the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays.

Hereinafter, for convenience of explanation, the act of allowing the pointer to be recognized without being in contact with the touch screen so that the pointer is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching the pointer on the screen is called "contact touch." The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

[ The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. Vibration is a representative example of the haptic effect generated by the haptic module 154. The intensity and pattern of vibration generated by the haptic module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

As shown in FIG. 10, the support 320 in which the second hinge shaft 315 provided on the other side of the earphone connecting plate 310 and the second hinge shaft 315 of the plurality of earphone connecting plates 310 are coupled to each other. ) May be further included.

Both sides of the second hinge shaft 315 are inserted into the coupling portion 321 formed on the support 320, and coupled to the support 320 so that the earphone connecting plate 310 rotates around the second hinge shaft 315. do. Since the second hinge shafts 315 of the plurality of earphone connecting plates 310 are all coupled to one support 320, the plurality of earphone connecting plates 310 may be integrally rotated.

The second hinge shaft 315 of the plurality of earphone connecting plates 310 is coupled to the support 320 to be positioned in parallel with the surface of the case 200. By the user moving the support 320, it is possible to easily adjust the rotation of the plurality of earphone connecting plate 310.

When the support 320 is not used, the earphone 320 is inserted into the insertion unit 210 so that the top surface of the support 320 coincides with the surface of the case 200 so that the earphone connecting plate 310 is stored in the insertion unit 210. do. In this case, the support 320 covers the opened upper surface of the insertion unit 210 so that the contact terminal 313 of the earphone connecting plate 310 is not exposed to the outside. Therefore, it is possible to prevent the failure caused by the inflow of foreign matters or the deterioration of the earphone sound quality.

At this time, the support 320 may further include a handle portion 322 formed to protrude on the upper surface. In the state in which the support 320 is inserted into the insertion unit 210 of the case 200, the user conveniently uses the handle 322 of the support 320 to insert the earphone connecting plate 310 from the insertion unit 210. Can be withdrawn.

Meanwhile, the mobile terminal according to the present invention may include three or four earphone connecting plates 310 as shown in FIG. 11. The number of earphone connecting plates 310 coupled to the case 200 corresponds to the number of terminals of the earphone plug P. Since the three-pole earphone and the four-pole earphone used in the mobile terminal have three and four terminals, respectively, three or four earphone connection plates 310 are also provided corresponding to the number of terminals of the earphone plug P.

The plurality of earphone connecting plates 310 are spaced apart from each other according to the position of the terminal of the earphone plug (P) to be contacted. Therefore, the contact terminals 313 (see FIG. 8) of the earphone connecting plate 310 are electrically connected to the terminals of the earphone plug P, respectively.

The mobile terminal according to the second preferred embodiment of the present invention includes an earphone connector coupled to the insertion unit and connected to the insertion unit so as to rotate about the first hinge shaft provided at one side of the case and the insertion unit.

According to the present invention, when the earphone is used, the earphone connector located inside the insertion part is rotated so that the connector of the side surface is exposed so that the earphone plug can be inserted in a diagonal direction. Therefore, the earphone plug insertion space inside the mobile terminal can be positioned horizontally with the case surface inside the insertion portion of the mobile terminal without using the vertical space with respect to the case surface, thereby utilizing the side space of the mobile terminal. Accordingly, it is possible to increase the utilization of the space inside the mobile terminal and to miniaturize the mobile terminal.

Hereinafter, the earphone connector of the present invention will be described in detail with reference to the accompanying drawings.

12 is a perspective view of a mobile terminal having an earphone connector according to a second exemplary embodiment of the present invention, and FIG. 13 is a partially enlarged view of the earphone connector.

First, the case 200 of the present invention includes an insertion portion 210 formed to be recessed inward. Insertion portion 210 is a space for positioning the earphone connector 500 therein when the earphone is not in use. Insertion portion 210 is formed to have a space larger than the size of the earphone connector 500 itself so that the earphone connector 500 can be rotated therein.

At this time, the insertion unit 210 is formed on the side of the case 200, the earphone connector 500 is coupled to the insertion unit 210 can eliminate the inconvenience of the user due to the earphone line when using the earphone.

Next, the earphone connector 500 of the present invention is a device that the earphone plug (P) is connected, it is coupled to the insertion portion 210 so that one side can rotate.
