The second sound output unit 152b may be additionally disposed on the terminal body. The second sound output unit 152b may implement a stereo function together with the first sound output unit 152a and may be used to implement a speakerphone mode during a call.

The terminal body may be provided with at least one antenna for wireless communication. The antenna may be built in the terminal body or formed in the case. For example, an antenna that forms part of the broadcast receiving module 111 (refer to FIG. 1A) may be configured to be pulled out from the terminal body. Alternatively, the antenna may be formed in a film type and attached to the inner side of the rear cover 103, or may be configured such that a case including a conductive material functions as an antenna.

The terminal body is provided with a power supply unit 190 (see FIG. 1A) for supplying power to the mobile terminal 100. The power supply unit 190 may include a battery 191 embedded in the terminal body or detachably configured from the outside of the terminal body.

The battery 191 may be configured to receive power through a power cable connected to the interface unit 160. In addition, the battery 191 may be configured to enable wireless charging through a wireless charger. The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

Meanwhile, in the drawing, the rear cover 103 is coupled to the rear case 102 to cover the battery 191 to limit the detachment of the battery 191 and to protect the battery 191 from external shock and foreign matter. To illustrate. When the battery 191 is detachably configured to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

An accessory may be added to the mobile terminal 100 to protect the appearance or to assist or expand the function of the mobile terminal 100. An example of such an accessory may be a cover or pouch that covers or accommodates at least one surface of the mobile terminal 100. The cover or pouch may be configured to be linked with the display unit 151 to expand the function of the mobile terminal 100. Another example of the accessory may be a touch pen for assisting or extending a touch input to a touch screen.

Meanwhile, in the present invention, the information processed by the mobile terminal can be displayed using a flexible display. Hereinafter, this will be described in more detail with reference to the accompanying drawings.

2 is a conceptual diagram illustrating another example of a deformable mobile terminal 200 according to the present invention.

As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of bending, bending, folding, twisting, and curling of the display unit 251. The deformable display unit 251 may be referred to as a "flexible display unit". Herein, the flexible display unit 251 may include both a general flexible display, an electronic paper, and a combination thereof. In general, the mobile terminal 200 may include features of or similar to the features of the mobile terminal 100 of FIGS. 1A-1C.

A general flexible display is a light and durable display that is fabricated on a thin and flexible substrate that can be bent, bent, folded, twisted or curled like a paper while maintaining the characteristics of a conventional flat panel display.

In addition, electronic paper is a display technology to which the characteristics of general ink are applied, and the use of reflected light may be different from that of a conventional flat panel display. Electronic paper can change information using twist balls or electrophoresis using capsules.

In a state where the flexible display unit 251 is not deformed (for example, a state having an infinite curvature radius, hereinafter referred to as a first state), the display area of the flexible display unit 251 is flat. In the state deformed by the external force in the first state (for example, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As shown, the information displayed in the second state may be visual information output on a curved surface. Such visual information is implemented by independently controlling light emission of a sub-pixel disposed in a matrix form. The unit pixel refers to a minimum unit for implementing one color.

The flexible display unit 251 may be placed in a bent state (eg, bent vertically or horizontally) instead of being flat in the first state. In this case, when an external force is applied to the flexible display unit 251, the flexible display unit 251 may be deformed into a flat state (or less curved state) or more curved state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made with respect to the flexible touch screen, the controller 180 (refer to FIG. 1A) may perform control corresponding to the touch input. The flexible touch screen may be configured to detect a touch input not only in the first state but also in the second state.

On the other hand, the mobile terminal 200 according to the present modification may be provided with deformation detection means for detecting the deformation of the flexible display unit 251. Such deformation detection means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting means may be provided in the flexible display unit 251 or the case 201 to sense information related to deformation of the flexible display unit 251. Herein, the information related to the deformation may include a direction in which the flexible display unit 251 is deformed, a degree of deformation, a deformation position, a deformation time, and an acceleration in which the flexible display 251 is restored. In addition, due to the bending of the flexible display unit 251 may be a variety of information that can be detected.

In addition, the controller 180 changes the information displayed on the flexible display unit 251 or changes the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251 detected by the deformation detecting means. It can generate a control signal for controlling the function of.

Meanwhile, the mobile terminal 200 according to the present modified example may include a case 201 for accommodating the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of characteristics of the flexible display unit 251.

In addition, the battery (not shown) included in the mobile terminal 200 may also be configured to be deformable together with the flexible display unit 251 by an external force in consideration of characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked up may be applied.

The state deformation of the flexible display unit 251 is not limited only by external force. For example, when the flexible display unit 251 has the first state, the flexible display unit 251 may be transformed into the second state by a command of a user or an application.

On the other hand, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the user mainly holding in the hand. Such wearable devices include a smart watch, a smart glass, a head mounted display (HMD), and the like. Hereinafter, examples of the mobile terminal extended to the wearable device will be described.

The wearable device may be configured to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 may detect (or recognize) a wearable device that can communicate around the mobile terminal 100. In addition, when the detected wearable device is a device that is authenticated to communicate with the mobile terminal 100, the controller 180 transmits at least a portion of data processed by the mobile terminal 100 through the short range communication module 114. Can be sent to. Therefore, the user may use data processed by the mobile terminal 100 through the wearable device. For example, when a call is received by the mobile terminal 100, a phone call may be performed through the wearable device, or when the message is received by the mobile terminal 100, the received message may be confirmed through the wearable device. .

3 is a perspective view illustrating an example of a watch type mobile terminal 300 according to another embodiment of the present invention.

Referring to FIG. 3, the watch-type mobile terminal 300 includes a main body 301 having a display unit 351 and a band 302 connected to the main body 301 to be worn on a wrist. In general, the mobile terminal 300 may include the features of the mobile terminal 100 of FIGS. 1A to 1C or similar features.

The main body 301 includes a case forming an external appearance. As shown in the drawing, the case may include a first case 301a and a second case 301b that provide an interior space for accommodating various electronic components.

The watch type mobile terminal 300 is configured to enable wireless communication, and the main body 301 may be provided with an antenna for wireless communication. On the other hand, the antenna can extend the performance using a case. For example, a case containing a conductive material may be configured to be electrically connected with the antenna to extend the ground area or the radiation area.

The display unit 351 may be disposed on the front surface of the main body 301 to output information, and the display unit 351 may be provided with a touch sensor and implemented as a touch screen. As illustrated, the window 351a of the display unit 351 may be mounted on the first case 301a to form the front surface of the terminal body together with the first case 301a.

The main body 301 may include a sound output unit 352, a camera 321, a microphone 322, a user input unit 323, and the like. When the display unit 351 is implemented as a touch screen, the display unit 351 may function as the user input unit 323, and thus a separate key may not be provided in the main body 301.

The band 302 is made to be worn on the wrist to surround the wrist, and may be formed of a flexible material to facilitate wearing. As such an example, the band 302 may be formed of leather, rubber, silicone, synthetic resin, or the like. In addition, the band 302 is configured to be detachable to the main body 301, the user can be configured to be replaced with various types of bands according to taste.

On the other hand, the band 302 can be used to extend the performance of the antenna. For example, the band may include a ground extension (not shown) electrically connected to the antenna to extend the ground area.

The band 302 may be provided with a fastener 302a. The fastener 302a may be implemented by a buckle, a snap-fit hook structure, a velcro (trade name), or the like, and may include an elastic section or material. . In this figure, an example in which the fastener 302a is implemented in the form of a buckle is shown.

4 is a perspective view illustrating an example of a glass type mobile terminal 400 according to another embodiment of the present invention.

Glass-type mobile terminal 400 is configured to be worn on the head of the human body, it may be provided with a frame portion (case, housing, etc.) for this. The frame portion may be formed of a flexible material to facilitate wearing. In the drawing, the frame part includes a first frame 401 and a second frame 402 of different materials. In general, the mobile terminal 400 may include features of or similar to the features of the mobile terminal 100 of FIGS. 1A-1C.

The frame part is supported by the head, and provides a space for mounting various components. As illustrated, electronic components such as the control module 480, the sound output module 452, and the like may be mounted in the frame unit. In addition, the lens 403 covering at least one of the left eye and the right eye may be detachably mounted to the frame part.

The control module 480 is configured to control various electronic components provided in the mobile terminal 400. The control module 480 may be understood as a configuration corresponding to the controller 180 described above. In this figure, the control module 480 is illustrated to be installed in the frame portion on one side head. However, the position of the control module 480 is not limited thereto.

The display unit 451 may be implemented in the form of a head mounted display (HMD). The HMD type is a display method mounted on the head and showing an image directly in front of the user's eyes. When the user wears the glass type mobile terminal 400, the display unit 451 may be disposed to correspond to at least one of the left eye and the right eye so as to provide an image directly in front of the user's eyes. In this figure, the display unit 451 is located at a portion corresponding to the right eye so that an image can be output toward the right eye of the user.

The display unit 451 may project an image to the eyes of a user using a prism. In addition, the prism can be formed translucent so that the user can see the projected image together with the general field of view (the range the user sees through the eye) together.

As such, the image output through the display unit 451 may be seen to overlap with the general field of view. The mobile terminal 400 may provide an augmented reality (AR) that displays a single image by superimposing a virtual image on a real image or a background using the characteristics of the display.

The camera 421 is disposed adjacent to at least one of the left eye and the right eye, and is formed to capture an image of the front. Since the camera 421 is located adjacent to the eye, the camera 421 may acquire a scene viewed by the user as an image.

In this figure, the camera 421 is provided in the control module 480, but is not necessarily limited thereto. The camera 421 may be installed in the frame portion, or may be provided in plural to acquire a stereoscopic image.

The glass type mobile terminal 400 may include user input units 423a and 423b operated to receive a control command. The user input units 423a and 423b may be adopted in any manner as long as it is a tactile manner in which the user operates while having a tactile feeling such as touch or push. In the drawing, the frame unit and the control module 480 are provided with push and touch input user input units 423a and 423b, respectively.

In addition, the glass-type mobile terminal 400 may be provided with a microphone (not shown) for receiving sound and processing it as electrical voice data and a sound output module 452 for outputting sound. The sound output module 452 may be configured to transmit sound in a general sound output method or a bone conduction method. When the sound output module 452 is implemented in a bone conduction manner, when the user wears the mobile terminal 400, the sound output module 452 is in close contact with the head and vibrates the skull to transmit sound.

Hereinafter, with reference to the accompanying drawings for the embodiments related to the present invention. It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

5 is a conceptual diagram of a mobile terminal 500 according to an embodiment of the present invention.

An acoustic discharge hole 503a is formed at the rear of the terminal body. For example, the sound discharge holes 503a may be formed in the rear cover 503. Sound generated inside the terminal body is emitted through the sound discharge hole 503a. Sound emitted through the sound discharge hole 503a may be transmitted to the user.

The mesh cover 553 is installed inside the terminal body. The mesh cover 553 covers the sound discharge holes 503a to prevent foreign substances from entering the inside of the terminal body through the sound discharge holes 503a. Accordingly, at least a part of the mesh cover 553 is exposed to the outside through the sound discharge hole 503a.

The present invention relates to a mobile terminal 500 capable of charging the battery 590 by placing the mobile terminal 500 on the charging cradle (520 of FIG. 9), and the terminal body is charged for charging the battery 590. It is formed to be mounted on the cradle. In particular, the present invention is characterized in that the battery 590 can be charged using the mesh cover 553 exposed through the sound discharge hole 503a. Therefore, the mobile terminal 500 proposed in the present invention does not have a separate terminal in contact with the charging cradle on the exterior as shown in FIG. 5.

Hereinafter, a detailed configuration of the present invention will be described with reference to the drawings related to the internal structure, the disassembled state, and the cross section of the mobile terminal 500 illustrated in FIG. 5.

FIG. 6 is a conceptual diagram illustrating the inside of the mobile terminal 500 shown in FIG. 5.

6 may be understood that the rear cover 503 and the rear case 502 are separated from the mobile terminal 500 of FIG. 5. However, unnecessary components are omitted for convenience of description. When the rear cover 503 is removed from the mobile terminal 500, the printed circuit board 580, the battery 590, the sound output module 552, the mesh cover 553, the interface unit 560, and the like are exposed.

The printed circuit board 580 is disposed inside the terminal body. The printed circuit board 580 may not overlap the battery 590 in the thickness direction of the mobile terminal 500 so as to minimize the thickness of the terminal body.

Most electronic components mounted on the mobile terminal 500 are electrically connected to the printed circuit board 580. The printed circuit board 580 may be understood as the controller 180 described with reference to FIG. 1A. Electronic components are electrically connected to the printed circuit board 580 to be controlled by the printed circuit board 580. The sound output module 552 and the battery 590 are also electrically connected to the printed circuit board 580.

The battery 590 supplies power required for the operation of the mobile terminal 500. Since the electronic components are electrically connected to the printed circuit board 580, the battery 590 may supply power required by the electronic components through the printed circuit board 580. On the contrary, the battery 590 receives the charging power supplied from the outside through the printed circuit board 580. Accordingly, the printed circuit board 580 is electrically connected to the battery 590 to transfer the charging power supplied through the charging cradle 520 of FIG. 9 to the battery 590.

The sound output module 552 is mounted inside the terminal body and is electrically connected to the printed circuit board 580. The mesh cover 553 is coupled to the sound output module 552. The sound output module 552 and the mesh cover 553 may be adhered to each other by double-sided tape. In the present invention, the mesh cover 553 not only prevents the inflow of foreign matter, but also functions as a terminal receiving charging power from the charging terminal 521 of FIG. 9.

The charging terminal includes a positive charging terminal (521a in FIG. 9) and a negative charging terminal (521b in FIG. 9) to supply charging power. Correspondingly, the mesh cover 553 has a positive terminal 553a and a negative terminal 553b, and the mesh cover 553 is electrically connected to the printed circuit board 580 by the conductive connecting member 554.

FIG. 7 is an exploded perspective view of the mobile terminal 500 shown in FIG. 5.

The rear cover 503 forms the appearance of the terminal body. The rear cover 503 may be combined with the front case 501 or the rear case 502. An acoustic discharge hole 503a may be formed in the rear cover 503.

The rear case 502 may set an arrangement area of the battery 590, the sound output module 552, and the mesh cover 553 through the openings 502b and 502c. The openings 502b and 502c include a first opening 502b and a second opening 502c. The first opening 502b sets up an arrangement area of the battery 590. The second opening portion 502c sets the arrangement area of the sound output module 552 and the mesh cover 553. The first opening 502b and the second opening 502c may be spaced apart from each other, but are not necessarily limited thereto.

The antenna module 510 may be disposed between the rear case 502 and the rear cover 503. The fastening hole 510a of the antenna module 510 corresponds to the fastening hole 502a of the rear case 502. Therefore, when one fastening member (not shown) such as a bolt is inserted into each of the fastening holes 510a and 502a, the antenna module 510 and the rear case 502 may be coupled to each other.

The mesh cover 553 is disposed between the sound output module 552 and the sound discharge hole 503a. As shown, the sound output module 552 may include a receiving portion 552a for receiving the mesh cover 553. The receiving portion 552a is formed so that at least part thereof corresponds to the mesh cover 553. When the mesh cover 553 is disposed in the accommodating portion, the mesh cover 553 is naturally disposed to correspond to the acoustic discharge hole 503a.

 The mesh cover 553 is formed of a conductive material so as to be electrically connected to the charging terminal (521 of FIG. 9) protruding toward the acoustic discharge hole 503a from the charging cradle (520 of FIG. 9). The mesh cover 553 is disposed to correspond to the charging terminal. Therefore, when the terminal body is mounted on the charging cradle for charging the battery 590, the charging terminal protruding from the charging cradle enters the acoustic discharge hole 503a and contacts the mesh cover 553. Since the mesh cover 553 is formed of a conductive material, the mesh cover 553 may be electrically connected to the charging terminal.

In addition, the mesh cover 553 is electrically connected to the printed circuit board 580 by the conductive connection member 554 to transfer the charging power supplied through the charging terminal to the battery 590. The conductive connecting member 554 may be integrally formed with the mesh cover 553. Electrical connection between the mesh cover 553 and the printed circuit board 580 is made by the conductive connecting member 554 and the contact terminal 581.

The contact terminal 581 is mounted on the printed circuit board 580 to electrically connect the contact object to the printed circuit board 580. As illustrated in FIG. 7, at least a part of the contact terminal 581 may protrude from the printed circuit board 580. Corresponding to the positive terminal 553a and the negative terminal 553b of the mesh cover 553, the contact terminal 581 may also include a positive contact terminal 581a and a negative contact terminal 581b.

The conductive connecting member 554 extends from the mesh cover 553 and contacts the contact terminal 581. The conductive connection member 554 may also include a positive connection member 554a and a negative connection member 554b. The positive connection member 554a electrically connects the positive terminal 553a and the positive contact terminal 581a of the mesh cover 553 to each other. The negative electrode connecting member 554b electrically connects the negative terminal 553b of the mesh cover 553 and the negative contact terminal 581b.

The sound output module 552 may be disposed to cover at least a portion of the printed circuit board 580. The sound output module 552 includes a penetrating portion 552b at a portion corresponding to the contact terminal 581 so as to expose the contact terminal 581. Thus, even when the sound output module 552 is disposed to cover the printed circuit board 580, the contact terminal 581 may be exposed through the through part 552b and the conductive connection member 554 may be contact terminal 581. Can be contacted.

FIG. 8 is a cross-sectional view taken along the line A-A of FIG. 5.

The acoustic discharge holes 503a are formed in the rear cover 503. The acoustic discharge hole 503a may penetrate the rear cover 503. The sound output module 552 is disposed to correspond to the sound discharge hole 503a.

The mesh cover 553 is disposed between the sound discharge hole 503a and the sound output module 552. The mesh cover 553 covers the sound discharge holes 503a. The sound output module 552 and the printed circuit board 580 may be disposed adjacent to each other.

The contact terminal 581 is mounted on the printed circuit board 580. The contact terminal 581 may be formed at least partially bent to provide an elastic force. The conductive connecting member 554 extends from the mesh cover 553 and contacts the contact terminal 581. The rear case 502 presses a contact point between the conductive connecting member 554 and the contact terminal 581 so as to maintain physical contact between the conductive connecting member 554 and the contact terminal 581. In detail, the rear case 502 may press the contact point as it is coupled to the front case 501. Thus, the electrical connection between the conductive connecting member 554 and the contact terminal 581 can be more reliably maintained by the rear case 502.

9 is a conceptual diagram illustrating charging the battery 590 by mounting the mobile terminal 500 of FIG. 5 to the charging cradle 520.

The charging cradle 520 is provided with a charging terminal 521 for supplying charging power to the contact object. The charging terminal 521 protrudes from the charging cradle 520. The charging terminal 521 includes a positive charging terminal 521a and a negative charging terminal 521b.

The terminal body is formed to be mounted on the charging cradle 520. For example, the charging cradle 520 may be formed with a seating portion 522 to seat the terminal body. When the terminal body is seated on the seating portion 522, the charging terminal 521 enters the sound discharge hole 503a and naturally contacts the mesh cover 553.

The charging power is supplied to the mobile terminal 500 through the charging terminal 521 and the mesh cover 553. The mesh cover 553 is electrically connected to the printed circuit board 580, and the printed circuit board 580 is electrically connected to the battery 590. Therefore, the charging power supplied through the charging terminal 521 and the mesh cover 553 may be transferred to the battery 590 through the printed circuit board 580.

When the terminal body is mounted on the charging cradle 520 to charge the battery 590, the mesh cover 553 is continuously pressed by the charging terminal 521. Accordingly, the durability of the mesh cover 553 can be lowered. However, in the present invention, since the mesh cover 553 is supported by the sound output module 552, degradation in durability of the mesh cover 553 can be prevented.

Hereinafter, another embodiment of the present invention will be described.

10 is a conceptual diagram of a mobile terminal 600 according to another embodiment of the present invention.

The acoustic discharge hole 603a is formed in the bottom surface of the terminal body. An interface unit 660 may be disposed in the center of the lower surface, and the acoustic discharge hole 603a may be disposed on the left side or the right side of the interface unit 660. In FIG. 10, the acoustic discharge holes 603a are disposed on the left side of the interface unit 660.

The mesh cover 653 covers the sound discharge holes 603a to prevent foreign substances from entering the inside of the terminal body through the sound discharge holes 603a. Since the mesh cover 653 is installed inside the terminal body, at least a part of the mesh cover 653 is exposed to the outside through the sound discharge hole 603a.

A dummy hole or a microphone hole 603b may be formed on the opposite side of the sound discharge hole 603a based on the interface unit 660. The dummy hole or the microphone hole 603b forms an symmetrical appearance with the acoustic discharge hole 603a. The mesh cover 653 'is disposed to cover the dummy hole or the microphone hole 603b similarly to the acoustic discharge hole 603a.

The dummy hole is to form an appearance symmetrical with the acoustic discharge hole 503a and does not have an additional function. On the other hand, a microphone module (not shown) is installed inside the microphone hole 603b. The microphone module receives the sound wave flowing through the microphone hole 603b and generates an electric signal according to the vibration of the sound wave.

However, the present invention is not necessarily limited to that shown in FIG. For example, the sound discharge holes 603a may be formed at left and right sides of the interface unit 660, respectively. For example, in the present invention, the mesh cover 653 includes a positive electrode terminal 603a and a negative electrode terminal 603b for charging a battery (not shown), and is disposed in the left and right acoustic discharge holes 603a. One of the mesh covers 653 may correspond to the positive terminal 653a and the other may correspond to the negative terminal 653b.

The mobile terminal 600 shown in FIG. 10 also has an acoustic discharge hole 603a and a mesh cover 653 in its exterior, but contacts the charging terminal (621 in FIG. 13) of the charging cradle (620 in FIG. 13) in its exterior. It does not have a separate terminal.

FIG. 11 is a conceptual diagram illustrating the inside of the mobile terminal 600 shown in FIG. 10.

11 may be understood that the rear cover 603 is separated from the mobile terminal 600 of FIG. 10. When the rear cover 603 is removed from the mobile terminal 600, the rear case 602 is exposed, and most of the components inside the mobile terminal 600 are covered by the rear case 602. However, as shown in FIG. 11, an opening 602c may be formed in at least a portion of the rear case 602, and the printed circuit board 680, the sound output module 652, and the conductive portion may be formed through the opening 602c. The connection member 654 may be exposed.

The contact terminal 681 may be mounted on the printed circuit board 680. The contact terminal 681 is electrically connected to the printed circuit board 680, and electrically connects the contact object to the printed circuit board 680. The contact terminal 681 may protrude from the printed circuit board 680.

The mesh cover 653 disposed on the bottom surface of the terminal body is electrically connected to the printed circuit board 680 by the conductive connecting member 654 and the contact terminal 681. The conductive connecting member 654 extends from the mesh cover 653 and contacts the contact terminal 581.

The mesh cover 653 is disposed to cover the sound discharge holes 603a. The mesh cover 653 includes a positive terminal 653a and a negative terminal 653b. A nonconductive member 655 is disposed between the positive terminal 653a and the negative terminal 653b to prevent a short circuit.

If the positive electrode terminal 653a and the negative electrode terminal 653b are respectively disposed to cover two acoustic discharge holes 503a spaced apart from each other, a short circuit does not occur even if there is no separate non-conductive member 655. However, as shown in FIG. 11, when the positive electrode terminal 653a and the negative electrode terminal 653b come into contact with each other to cover one acoustic discharge hole 603a, a short circuit occurs in the mesh cover 653. If the positive terminal 653a and the negative terminal 653b are spaced apart from each other, even if the non-conductive member 655 does not exist, a short circuit does not occur, but foreign substances may flow through the spaced gaps. Therefore, in the case where the positive electrode terminal 653a and the negative electrode terminal 653b cover one acoustic discharge hole 603a, it is preferable that the non-conductive member 655 is disposed to prevent a short circuit.

12 is a cross-sectional view taken along line B-B of FIG. 10.

The display unit 651 forms the front surface of the terminal body, and the rear cover 603 forms the rear surface of the terminal body. The rear case 602 is disposed inside the terminal body. At least a portion of the rear case 602 is exposed to the bottom surface of the terminal body, and the acoustic discharge hole 603a is disposed on the bottom surface of the terminal body.

The sound output module 652 is disposed to correspond to the sound discharge hole 603a to emit sound toward the sound discharge hole 603a. The mesh cover 653 is disposed to cover the sound discharge holes 603a.

The sound guide portion 602d may be formed in the rear case 602. The sound guide part 602d extends from the edge of the sound discharge hole 603a to the mesh cover 653 so as to guide the sound emitted from the sound output module 652 to the sound discharge hole 603a. In addition, the sound guide unit 602d may press the net cover 653 in the direction in which the sound output module 652 is disposed to prevent the net cover 653 from being separated.

The contact terminal 681 is mounted on the printed circuit board 680. The contact terminal 681 may be formed at least partially bent to provide an elastic force. The conductive connecting member 654 extends from the mesh cover 653 and contacts the contact terminal 581.

The antenna module 610 is disposed inside the terminal body. The antenna module 610 is disposed in the opening 602c described with reference to FIG. 11, and the antenna module 610 has a conductive connecting member 654 to maintain a physical contact state between the conductive connecting member 654 and the contact terminal 681. And the contact point of the contact terminal 681 can be pressed.

FIG. 13 is a conceptual view illustrating charging the battery 690 by mounting the mobile terminal 600 of FIG. 10 to the charging cradle 520.

The charging cradle 620 is provided with a charging terminal 621 that can supply charging power to the contact object. The charging terminal 621 protrudes from the charging cradle 620. The charging terminal 621 includes a positive charging terminal 621a and a negative charging terminal 621b.

The terminal body is formed to be mounted on the charging cradle 620. For example, the charging cradle 620 may be formed with a seating portion 622 to seat the terminal body. When the terminal body is seated on the seating portion 622, the charging terminal 621 naturally contacts the mesh cover 653 through the sound discharge hole 603a.

The charging power is supplied to the mobile terminal 600 through the charging terminal 621 and the mesh cover 653. The mesh cover 653 is electrically connected to the printed circuit board 680 of FIG. 12, and the printed circuit board 680 is electrically connected to the battery 690. Therefore, the charging power supplied through the charging terminal 621 and the mesh cover 653 may be transferred to the battery 690 through the printed circuit board 680.

When the terminal body is mounted on the charging cradle 620 to charge the battery 690, the mesh cover 653 is continuously pressed by the charging terminal 621. Accordingly, the durability of the mesh cover 653 can be lowered. However, in the present invention, since the mesh cover 653 is supported by the sound output module 652, the degradation in durability of the mesh cover 653 can be prevented.

In the present invention, the mesh cover of the conductive material is disposed in the sound discharge hole for the sound output, the mesh cover is electrically connected to the printed circuit board by the conductive connecting member. By such a configuration, the present invention may not include a separate terminal for charging in the appearance of the terminal body. The present invention can transfer the charging power supplied from the charging terminal to the battery using a mesh cover for preventing the foreign matter as a terminal.

Compared with the prior art each having a net cover of the sound discharge hole and a terminal for charging, the present invention can reduce the number of components exposed to the appearance of the terminal body. As a result, the number of parts and manufacturing cost of the mobile terminal can be saved, and the internal space of the terminal can be saved. In addition, there is an advantage that can reduce the number of processes in the manufacturing process of the mobile terminal.

14 is a conceptual diagram of a mobile terminal 700 according to another embodiment of the present invention.

The mobile terminal 700 includes an interface unit 760 for electrical connection between the terminal 700 and an external device. The interface unit 760 serves as a path for an external device connected to the mobile terminal 700. The mobile terminal 700 may perform appropriate control related to the external device in response to the connection of the external device to the interface unit 760.

The interface unit 760 may be formed on the terminal body, and as illustrated, the interface unit 760 may be formed on the bottom surface of the terminal body. However, the present invention is not necessarily limited thereto, and the interface unit 760 may be formed on the side or the rear of the terminal body.

The interface unit 760 includes a cover 762, and the cover (see 762 in FIG. 15) is formed to protect the interface unit 760. In order to form a unitary appearance of the terminal body, the outer circumferential surface of the cover 762 may be formed with the same curvature as the terminal body. A socket (see 761 of FIG. 15) is disposed inside the cover 762. The case where the cover 762 is disposed to cover the socket 761 may be referred to as a closed state, and the exposed state of the socket 761 may be referred to as an open state (hereinafter, referred to as a closed state and an open state). Description is omitted). 14 illustrates a closed state, and opening the cover 762 exposes the socket 761. When an external device such as a connector is inserted into the socket 761, the external device and the terminal 700 are electrically connected to each other.

The present invention relates to a mobile terminal 700 capable of charging a battery by mounting the mobile terminal 700 in a charging cradle (see 720 of FIG. 20), and the terminal body is connected to a charging cradle 720 for charging a battery. It is formed to be mountable. In particular, the present invention is characterized in that the battery (see 790 of FIG. 20) can be charged using the cover 762 of the interface unit 760. Therefore, in the present invention, the mobile terminal 700 does not have a separate terminal in contact with the charging cradle 720 on its exterior as shown in FIG. 14.

Hereinafter, an internal structure of the interface unit 760 exposed when the cover 762 is opened will be described.

FIG. 15 is a conceptual diagram illustrating an open state in which the cover 762 is opened to expose the socket 761 in the mobile terminal 700 illustrated in FIG. 14.

The terminal body 701 has a lever groove 702 formed adjacent to the cover 762 so that the cover 762 can be switched from the closed state to the open state. When a finger or other object is inserted into the lever groove and pulled using the principle of the lever, the coupling relationship between the cover 762 and the terminal body 701 is partially released. Then, when the cover 762 is rotated, the cover 762 is switched from the closed state to the open state covering the socket 761.

When the cover 762 is switched to the open state, the cover 762 is not completely separated from the terminal body 701. At least part of the cover 762 is constrained to the terminal body 701, and only the other part is spaced apart from the terminal body 701.

When the cover 762 is switched to the open state, the socket 761 is exposed to the outside of the terminal body 701. The socket 761 is formed to receive at least a portion of an external device inserted therein. When an external device is inserted into the socket 761, the external device may be electrically connected to the printed circuit board 780. The external device may be a charging cable or a data cable, and the mobile terminal 700 may receive charging power through the charging cable or perform data communication with an external device via a data cable in a wired manner. However, the present invention does not limit the type of external device.

The socket 761 is electrically connected to the printed circuit board 780. In addition, the printed circuit board 780 and the battery (see 790 of FIG. 20) may be electrically connected. Therefore, the charging power supplied through the external device connected to the socket 761 may be transferred to the battery 790 through the printed circuit board 780. However, the present invention is formed so that the external terminal 764 of the cover 762 can be used for charging in addition to the method of charging by inserting an external device such as a cable into the socket 761.

The terminal body 701 may include a magnet 703 at a position adjacent to the socket 761. The magnet part 703 will be described later with reference to FIG. 16.

Hereinafter, a structure capable of charging the battery 790 of FIG. 20 using the interface unit 760 will be described with reference to an internal structure diagram of the mobile terminal 700.

FIG. 16 is a conceptual diagram illustrating the inside of the mobile terminal 700 illustrated in FIG. 14.

The printed circuit board 780 is disposed in the terminal body 701. The printed circuit board 780 is electrically connected to the battery 790 of FIG. 20 to transfer the charging power supplied through the charging terminal of the charging cradle 720 of FIG. 20 (FIG. 1421 of FIG. 20) to the battery.

The interface unit 760 includes a socket 761, a cover 762, an internal connection 763, and an external terminal 764, which will be described in detail below for each component of the interface unit 760. .

The socket 761 is electrically connected to the printed circuit board 780. As shown in FIG. 16, the socket 761 may be directly mounted on the printed circuit board 780 to be electrically connected to the printed circuit board 780. Alternatively, the socket 761 may be connected to the printed circuit board 780 by a separate connector (not shown) or a flexible printed circuit board (not shown).

The cover 762 forms the appearance of the terminal body 701 in the closed state.

The internal connection 763 protrudes from the cover 762. The internal connection 763 is formed to be inserted into the socket 761 so as to be electrically connected to the printed circuit board 780. With the cover 762 closed, the internal connection 763 is inserted into the socket 761. Accordingly, the internal connection 763 may be electrically connected to the socket 761, and the internal connection 763 may be electrically connected to the printed circuit board 780 through the socket 761.

Conversely, with the cover 762 open, the internal connection 763 is drawn out of the socket 761. The socket 761 may be provided with a guide part (not shown) for guiding insertion and withdrawal of the internal connection part 763. The internal connection 763 can be inserted into or withdrawn from the socket 761 along the guide.

The external terminal 764 is electrically connected to the internal connection 763. The internal connection 763 and the external terminal 764 may be connected to each other through the cover 762. Therefore, when a current flows through the internal connection portion 763, a current also flows through the external terminal 764.

The cover 762 is formed of a non-conductive material to prevent a short circuit. When the external terminals 764 are in contact with each other, a short circuit may occur while an arbitrary closed circuit is formed. Therefore, since the cover 762 is formed of a non-conductive material, the external terminals 764 may be separated from each other to prevent occurrence of a short circuit.

The external terminal 764 is formed on the opposite side of the internal connection 763 and exposed to the outside of the terminal body 701. For example, the cover 762 may include a non-exposed surface (see 762a of FIG. 17A) that is not exposed to the outside in a closed state, and an exposed surface (see 762b of FIG. 17B) that is exposed to the outside. The non-exposed surface 762a and the exposed surface 762b are formed on opposite surfaces of each other. The external terminal 764 may be formed on the exposed surface 762b, and the internal connection 763 may be formed on the non-exposed surface 762a.

A charging terminal (721 of FIG. 20) may be formed in the charging cradle (720 of FIG. 20) for charging the battery (790 of FIG. 20), and the external terminal 764 may be charged with the charging terminal 721. It may be disposed to correspond to the charging terminal 721 to receive the. The specific contact structure of the external terminal 764 and the charging terminal 721 will be described later.

The interface unit 760 further includes a connection member 765.

The connecting member 765 protrudes from the cover 762 to be coupled to the terminal body 701 to prevent the cover 762 from being completely separated or separated from the terminal body 701 during the process of switching from the closed state to the open state. do. When the cover 762 is switched from the closed state to the open state, the cover 762 is spaced apart from the socket 761. However, the connection member 765 is constrained to the terminal body 701. Thus, even when the cover 762 is switched from the closed state to the open state, the cover 762 only moves away from the terminal body 701 and is not completely separated.

The cover 762 may include a metal member 766, and the terminal body 701 may include a magnet part 703 corresponding to the metal member 766. The metal member 766 is disposed on the opposite side of the connecting member 765 on the non-exposed surface 761a of the cover 762 with respect to the internal connecting member 763. For example, the metal member 766 may be formed at one side of the internal connection part 763 on the non-exposed surface 761a of the cover 762, and the metal member 766 may be formed at the other side of the internal connection part 763. .

The magnet part 703 is disposed to correspond to the metal member 766 to prevent the cover 762 from being spaced apart by using a magnetic force (human force). While the cover 762 is switched from the open state to the closed state, the metal member 766 becomes closer to the magnet portion 703. When the metal member 766 enters the magnetic field region of the magnet portion 703, a magnetic force (human force) acts between the magnet portion 703 and the metal member 766. Therefore, the magnet 703 may prevent the cover 762 from being spaced apart from the terminal body 701 until an external force is applied to overcome the attraction force.

Hereinafter, the detailed structure of the cover 762 will be described.

17A is a conceptual diagram illustrating a cover 762 separated from the mobile terminal 700 of FIG. 14. 17B is a conceptual view of the cover 762 of FIG. 17A viewed from another direction.

Referring first to FIG. 17A, an internal connection 763 is formed to protrude from the non-exposed surface 762a of the cover 762. The internal connection 763 is removably formed in the socket 761 and has pins 763a electrically connected to the socket 761 when inserted into the socket 761. The pins 763a may be formed in a number corresponding to the pins (see 761a of FIG. 19) of the socket 761, and correspond to the external terminal 764. 17A and 17B, the pins 763a of the internal connection 763 are formed in a one-to-one correspondence with the external terminal 764. Thus, the inner connection 763 has five pins 763a to correspond to the five external terminals 764.

The internal connection 763 may have a hook coupling 763b. The hook coupling portion 763b is formed to correspond to the groove 761b of FIG. 19 formed in the socket 761. The hook coupling portion 763b may be partially flipped while the internal connection 763 is inserted into the socket 761. When the internal connection 763 is fully inserted into the socket 761, the hooked-up portion 763b that has been folded is restored and seated in the groove 761b of the socket 761. The hook coupling 763b prevents any detachment of the internal connection 763 from the socket 761 and maintains contact between the socket 761 and the internal connection 763.

The connection member 765 is disposed on one side of the internal connection 763 and protrudes from the cover 762. The connection member 765 is coupled to the terminal body 701, and the locking jaw 765a is formed at the end of the connection member 765. Accordingly, the connecting member 765 may be withdrawn from the terminal body 701 by the length protruding from the cover 762, but is not separated from the terminal body 701 by the locking step 765a.

The metal member 766 is disposed on the other side of the internal connection 763. The metal member 766 is disposed to correspond to the magnet part 703 of the terminal body 701. Therefore, when the internal connection portion 763 is inserted into the socket 761, the metal member 766 abuts against the magnet portion 703, and a magnetic force (gravity) between the magnet portion 703 and the metal member 766. This will work. It is possible to prevent the cover 762 from being arbitrarily separated from the terminal body 701 by the magnetic force of the magnet part 703 and the metal member 766.

The interface unit 760 may further include an airtight unit 767a. Since the interface unit 760 is for connection with an external device, the socket 761 may be exposed to the outside of the terminal body 701 for connection with an external device. Accordingly, fluid may flow into the terminal body 701 through the socket 761. In addition, if there is no airtight portion 767a, the fluid may flow through the gap between the cover 762 and the terminal body 701 even when the cover 762 is closed.

The airtight portion 767a is formed to surround the edge of the cover 762 to prevent the fluid from flowing into the terminal body 701 through the socket 761. The airtight portion 767a may be formed of an elastic material such as rubber, for example, and may be formed in the form of an O-ring. The airtight unit 767a may implement the waterproof terminal 700.

Next, referring to FIG. 17B, the cover 762 has an exposed surface exposed to the outside of the terminal body 701 in a closed state. The external terminal 764 is disposed on the exposed surface of the cover 762. When the terminal body 701 is mounted on the charging cradle (see 720 of FIG. 20), the external terminal 764 contacts the charging terminal (721 of FIG. 20) of the charging cradle 720. Accordingly, the external terminal 764 and the charging terminal 721 is electrically connected.

In FIG. 17B, the airtight portion 767a described above is removed from the edge of the cover 762. A seating groove 767b may be formed at an edge of the cover 762, and the seating groove 767b provides a coupling space of the airtight portion 767a.

Hereinafter, an internal structure of the mobile terminal 700 illustrated in FIG. 14 will be described.

18 is a conceptual diagram illustrating an internal structure of the mobile terminal 700 illustrated in FIG. 14.

The cover 762 is in a closed state, and the internal connection 763 is inserted into the socket 761. The socket 761 is mounted on the printed circuit board 780 and is electrically connected to the printed circuit board 780. Therefore, in the state where the internal connection part 763 is inserted into the socket 761, the printed circuit board 780, the internal connection part 763, and the external terminal 764 are electrically connected to each other.

Since the metal member 766 is disposed adjacent to the magnet portion 703, a magnetic force (human force) acts between the magnet portion 703 and the metal member 766. In addition, the connection member 765 is inserted into the terminal body 701 and has a length that can be drawn out from the terminal body 701. Since the locking jaw 765a is formed at the end of the connection member 765, the arbitrary separation of the connection member 765 from the terminal body 701 is limited.

When the cover 762 is spaced apart from the terminal body 701 by applying an external force sufficient to overcome the attractive force of the metal member 766 and the magnet portion 703, the internal connection 763 is drawn out of the socket 761. In addition, the connection member 765 is withdrawn from the terminal body 701 until the locking jaw 765a is caught by the terminal body 701. Through this process, the cover 762 may be switched from the closed state to the open state.

19 is a cross-sectional view taken along line C-C of FIG. 14.

19, the cover 762 is closed as in FIG. 18, and the internal connection 763 is inserted into the socket 761. The pins 763a of the internal connection 763 contact each other with the pins 761a of the socket 761, so that the internal connection 763 and the socket 761 are electrically connected to each other.

The internal connection 763 has a hook coupling 763b and is seated in a groove 761b formed in the socket 761. Accordingly, the internal connection 763 may not be randomly released from the socket 761.

20 is a conceptual diagram illustrating charging the battery 790 by mounting the mobile terminal 700 of FIG. 14 to a charging cradle 720.

The charging cradle 720 is provided with a charging terminal 721 for supplying charging power to the contact object. The charging terminal 721 may protrude from the charging cradle 720.

The terminal body is formed to be mounted on the charging cradle 720. For example, the charging cradle 720 may be formed with a seating portion 722 to seat the terminal body. When the terminal body is mounted on the seating portion 722, the charging terminal 721 naturally contacts the external terminal 764.

The charging power is supplied to the mobile terminal 700 through the charging terminal 721 and the external terminal 764. The external terminal 764 is electrically connected to the printed circuit board 780 through an internal connection 763 and a socket 761, and the printed circuit board 780 is electrically connected to the battery. Therefore, the charging power supplied through the charging terminal 721 and the external terminal 764 may be transferred to the battery 790 through the printed circuit board 780.

In the present invention, the inner connection portion and the outer terminal are formed on both sides of the cover for protecting the socket of the interface portion, respectively. In addition, the internal connection is inserted into the socket, which is electrically connected to the printed circuit board. It is electrically connected to each other by internal connection and external terminal. By such a configuration, the present invention may not include a separate terminal for charging in the appearance of the terminal body. The present invention can transfer the charging power supplied from the charging terminal to the battery using the external terminal formed on the cover as a terminal.

Compared with the prior art each having a terminal and an interface unit for charging, the present invention can reduce the number of components exposed to the appearance of the terminal body. As a result, the number of parts and manufacturing cost of the mobile terminal can be saved, and the internal space of the terminal can be saved. In addition, there is an advantage that can reduce the number of processes in the manufacturing process of the mobile terminal.

The mobile terminal described above is not limited to the configuration and method of the embodiments described above, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications can be made.

The present invention can be used in a variety of industries, including a mobile terminal for charging the battery mounted on the charging cradle.
