The mobile terminal 100 may include two or more display units according to its embodiment. For example, a plurality of display units may be separately or integrally disposed on one surface or disposed on different surfaces of the mobile terminal, respectively.
The mobile electronic device 200 illustrated in FIG. 3 may include a reading device 204, and after the reading device 204 is separated, a communication module 210 (See FIG. 5) may be mounted to the area from which the reading device 204 has been removed. The communication module 210 will now be described in more detail with reference to FIGS. 4 and 5. FIG. 4 is an exploded perspective view showing a portion of the mobile electronic device of FIG. 2, and FIG. 5 is an exploded view of a communication module mounted in an accommodation chamber of FIG. 4.
With reference to FIG. 4, the reading device 204 of a storage medium is detachably mounted to the side of the first body 201. The storage medium may be a CD, a DVD, and the like, and the reading device 204, which may be a CD ROM driver, a DVD ROM driver, and the like, reads the records of the storage medium.
As illustrated, the first body 201 includes an accommodation chamber 205 in order to receive the reading device 204 when the reading device 204 is coupled to the mobile electronic device 200. The accommodation chamber 205 is limited by a front case 201a and a rear case 201b of the first body 201. An opening of the accommodation chamber 205 is formed at the side of the first body 201, and a connection port 206 electrically connected to the reading device 204 is disposed in the accommodation chamber 205. When the reading device 204 is separated, the communication module 210 may be inserted in the accommodation chamber 205.
With reference to FIGS. 4 and 5, the communication module 210 is formed to transmit and receive a radio signal, and is electrically connected to the first body 201 to perform controlling corresponding to the radio signal. For example, the communication module 210 includes a communication port 215 which can be connected to the connection port 20, and in this case, the communication port 215 is configured to be connected to the connection port 206 in a similar or same manner as a connection port 204a of the reading device 204 does.
As illustrated in FIG. 5, the communication module 210 includes a housing 211, antennas 212a and 212b, a circuit board 213, and a card socket 2114.
The housing 211 is configured to have the same or similar external appearance as that of the reading device 204 so as to be accommodated in the accommodation chamber 205.
The antennas 212a and 212b are configured to transmit and receive a radio signal. The antennas 212a and 212b may be configured such that their length varies, and a frequency band for a transmission and reception may be set according to the length of the antennas 212a and 212b. The antennas 212a and 212b may be pivotably mounted on the housing 211 such that they are protruded from the first body 201.
For example, mounting holes 216a and 216b are formed on one surface of the housing 211 and the antenna 212a and 212b are detachably inserted in the mounting holes 216a and 216b and rotated in the mounting holes 216a and 216b. In addition, the antennas 212a and 212b may be formed to be folded by a hinge, and a plurality of antennas may be provided to transmit and receive radio signals of multiple bands.
The circuit board 213 is disposed within the housing 211. The circuit board 213 may be formed to process a radio signal transmitted and received through the antennas. For example, an electronic element 217 may be mounted on one surface of the circuit board 213 in order to perform 3G or 4G radio communication. The circuit board 213 may be connected to the communication port 215 by means of a flexible circuit board. However, the present invention is not limited thereto, and the 3G or 4G radio communication device may be installed in the first body 201 or the second body 202, and the electronic device 217 may be optional to perform radio communication such as EV-DO, HSPA, WiBro, LTE, and the like.
The card socket 214 is stacked on the circuit board 213 and configured to accommodate an external card. In detail, the accommodated external card, having a standardized form such as a SIM (Subscriber Identification Module) or a UIM (User Information Module), is inserted into the card socket 214 and electrically connected to the circuit board 213. The card socket 214 is mounted on the opposite side of the electronic element 217 on the circuit board 213, thereby exhibiting an effect of shield can.
As illustrated, the card socket 214 is disposed between the mounting holes 216a and 216b of the antennas 212a and 212b, and a door 218 for opening and closing the card socket 214 may be mounted on the housing 211. The mounting holes 216a and 216b and the door 218 may be disposed on the side of the first body 201 when the communication module 210 is mounted on the first body 201.
In this manner, the interface allowing the reading device 204 to be detachably mounted and the communication module 210 to be selectively mounted is configured, so when the user does not use the reading device 204, he may use an Internet service, or the like, using a mobile communication network. Also, because the communication module 210 is not always mounted in the mobile electronic device, the mobile electronic device can have a smaller size.
Also, because the communication module 210 is mounted in the accommodation chamber 205 of the first body 201, it does not affect the transmission and reception performance of the communication module 210. Accordingly, the components in relation to radio communication can be packaged into the communication module 210.
FIG. 6 is a flow chart illustrating the process of a method of using the communication module of FIG. 4, and FIG. 7 is a circuit diagram showing a circuit connection of the connection port 206 of FIG. 4.
A method of using the communication module will now be described. The reading device is usually mounted in the mobile electronic device, and in order to use a mobile communication data service, the user may separate the reading device from the mobile electronic device.
With reference to FIG. 6, the user mounts the communication module and boots the mobile electronic device. A newly mounted mobile communication product is searched on an O/S, and the user may install software (driver, application) of the corresponding communication module. The user mounts the antennas, positions them upright, executes a CM (Connection Manager) program, and connects the Internet.
An electrical connection circuit of the connection port 206 and the communication port 215 (See FIG. 5) may be designed such that a particular pin may be used for a USB D+/D− signal for using the communication module in order to share a connector with an existing ODD (Optical Disk Drive) interface.
For example, as shown in FIG. 7, pins #45 and #46 of the connection port 206 may be designated as ground (GND) pins of the reading device, and as the pins #45 and #46 are connected to a USB port of the electronic element, an interface is implemented between the firs body and the electronic element. Also, the card socket may be implemented as an 8-pin socket interface in a push-push form.
FIG. 8 is an exploded view showing a mobile electronic device according to another exemplary embodiment of the present invention. Description of the same or similar configuration as that of the former embodiment described above with reference to FIG. 5 will be omitted.
As illustrated, antennas 312a and 312b are coupled to a housing 311 of a communication module 310 such that they are not separated. In detail, the antennas 312a and 312b are disposed to pivot on a circumferential surface of the housing 311.
A portion of a front surface of a front case 301a corresponding to the opening of the accommodation chamber may be cut out, and the antennas 312a and 312b are disposed on the cutout portion 301c when the communication module 310 is mounted in the accommodation chamber. The antennas 312a and 312b are protruded through the cutout portion 301c through pivoting operation, whereby a transmission and reception of a radio signal can be facilitated.
The mobile electronic device according to an exemplary embodiment of the present invention does not require a component installation space for radio communication because the communication module is electively coupled.
In addition, because the communication module is mounted in the accommodation chamber of the reading device, the display does not affect the transmission and reception performance of the communication module. Also, the design space corresponding to the accommodation chamber can be secured, whereby the components in relation to radio communication can be packaged to the communication module.
As the exemplary embodiments may be implemented in several forms without departing from the characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims. Therefore, various changes and modifications that fall within the scope of the claims, or equivalents of such scope are therefore intended to be embraced by the appended claims.
