As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal 100 can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal. The location information module 115 is to obtain the position of the mobile terminal 100 and thus is not limited to any module for directly detect or calculate the position of the mobile terminal 100.
The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.
The microphone 122 is generally implemented to permit audio input to the mobile terminal 100. The audio input can be processed in various manners according to a function being executed in the mobile terminal 100. If desired, the microphone 122 may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.
The user input unit 123 is a component that permits input by a user. Such user input may enable the controller 180 to control operation of the mobile terminal 100.

As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.
The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.
The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.
The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.
The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like). In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.
A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.
As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.
When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180, the controller 180, and combinations thereof.
In some embodiments, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.
The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.
If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.
The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.
Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.
The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images.
A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.
A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.
Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.
The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.
An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.
A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.
The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.
The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.
When the mobile terminal 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.
The memory 170 can store programs to support operations of the controller 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.

The mobile terminal 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.
The controller 180 may typically control the general operations of the mobile terminal 100. For example, the controller 180 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.
The controller 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.
The power supply unit 190 receives external power or provides internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.
The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 160 to which an external charger for supplying power to recharge the battery is electrically connected.
As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.
Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.
Referring now to
In the followings, a terminal body is used to designate the mobile terminal 100 as a single assembly.
The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally positioned between the front case 101 and the rear case 102.
The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151a of the display unit 151 may be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.
In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 are externally exposed.
As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121b or an audio output module 152b.
The cases 101, 102, 103 may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like.
As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal 100 may be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body is formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface.
If desired, the mobile terminal 100 may include a waterproofing unit (not shown) for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.
The mobile terminal 100 may include a display unit 151, first and second audio output modules 152a, 152b, a proximity sensor 141, an illumination sensor 142, an optical output module 154, first and second cameras 121a, 121b, first and second manipulation units 123a, 123b, a microphone 122, an interface unit 160 and the like.
However, it is to be understood that alternative arrangements are possible and within the teachings of the instant disclosure. Some components may be omitted or rearranged. For example, the first manipulation unit 123a may be located on another surface of the terminal body, and the second audio output module 152b may be located on the side surface of the terminal body.
The display unit 151 outputs information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application executed at the mobile terminal 100, or user interface (UI)/graphic user interface (GUI) information according to the execution screen information.
Examples of such suitable display devices include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, an e-ink display, and combinations thereof.
The display unit 151 may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.
The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.
The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window 151a and a display on a rear surface of the window 151a, or a metal wire which is patterned directly on the rear surface of the window 151a. Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.
The display unit 151 may also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see
The first audio output module 152a may be implemented in the form of a speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like.
The window 151a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151a and the front case 101). In this case, a hole independently formed to output audio sounds may not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.
The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit 154 to stop the light output.
The first camera 121a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170.
The first and second manipulation units 123a and 123b are examples of the user input unit 123, which may be manipulated by a user to provide input to the mobile terminal 100. The first and second manipulation units 123a and 123b may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123a and 123b may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.
Input received at the first and second manipulation units 123a and 123b may be used in various ways. For example, the first manipulation unit 123a may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit 123b may be used by the user to provide an input to control a volume level being output from the first or second audio output modules 152a or 152b, to switch to a touch recognition mode of the display unit 151, or the like.
As another example of the user input unit 123, a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152a or 152b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof.
The rear input unit may be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body.
Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123a in the rear input unit. As such, in situations where the first manipulation unit 123a is omitted from the front side, the display unit 151 can have a larger screen.
As a further alternative, the mobile terminal 100 may include a finger scan sensor which scans a user's fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit 151 or implemented in the user input unit 123.
The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.
The interface unit 160 may serve as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.
The second camera 121b is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121a. If desired, second camera 121a may alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown.
The second camera 121b can include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera 121b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.
As shown in
As shown in
At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.
A power supply unit 190 (see
The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance.
The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.
An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 can be also provided on the mobile terminal 100. As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch may cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen.
A vibrator 210 generates a high frequency that repels a mosquito by vibration. The vibrator 210 may include a copperplate layer 211 and a ceramic layer 212. Terminals may be respectively connected to the copperplate layer 211 and the ceramic layer 212, and may vibrate as an electric signal is received. One of the two terminals may be electrically connected to the copperplate layer 211, and the other thereof may be electrically connected to the ceramic layer 212. The two terminals may be drawn to the outside through a flexible printed circuit board 213.
An upper casing 220 and a lower casing 230 mount the vibrator 210 therebetween to fix the vibrator 210 and to simultaneously secure a vibration space of the vibrator 210.
The upper casing 220 may be disposed in a direction in which the high frequency generated from the vibrator 210 is emitted. The upper casing 220 may define multi-holes therein to secure a path through which the high frequency is emitted. The multi-holes of the upper casing 220 are defined as first multi-holes 221 to be distinguished from multi-holes of another component to be described later.
The lower casing 230 may be coupled to the upper casing 220 to define a separate space 241 therein. At least a portion of the separate space 241 may be the vibration space of the vibrator 210.
A first face 2201 of the upper casing 220 may provide a face with the first multi-holes 221 defined therein. The first face 2201 may be spaced apart from a top face of the vibrator 210 by a first distance. The first distance may be 0.5 mm.
A second face 2202 of the upper casing 220 may form a step from the first face 2201 to support an outer peripheral region of a front face 2101 of the vibrator 210. That is, the second face 2202 serves to hold the vibrator 210. The support of the front face 2101 of the vibrator 210 by the second face 2202 may be implemented using an adhesive tape. For convenience, the adhesive tape disposed on the front face 2101 of the vibrator 210 is defined as an upper tape 242. A spacing between the second face 2202 and the vibrator 210 may be specified in consideration of a thickness of the upper tape 242.
A planar portion 232 of the lower casing 230 may include a face corresponding to the first face 2201 of the upper casing 220. That is, the planar portion 232 may be disposed to be spaced apart from a bottom face of the vibrator 210 by a second distance. Like the first distance, the second distance may be 0.5 mm from a rear face of the vibrator 210. The first distance or the second distance is based on the most front face or the most rear face of the vibrator 210.
The separate space 241 may be defined between the first face 2201 of the upper casing 220 and the planar portion 232 of the lower casing 230 to secure the vibration space of the vibrator 210.
The protruding portion 231 may form a bend from the planar portion 232 of the lower casing 230 to protrude inward to support an outer peripheral region of the bottom face of the vibrator 210. That is, the second face 2202 of the upper casing 220 and the protruding portion 231 respectively hold the outer peripheral regions of the front and the rear faces of the vibrator 210. Like the front face 2101 of the vibrator 210, an adhesive tape may be disposed between the protruding portion 231 and the vibrator 210, so that the protruding portion 231 and the vibrator 210 may be fixed to each other. For convenience, such adhesive tape is defined as a lower tape 243.
The upper tape 242 and the lower tape 243 may contain a soft material so as not to affect the number of vibrations considered in a design as much as possible. When the upper tape 242 and the lower tape 243 are made of a hard material, in addition to the vibrator 210, the upper casing 220 and the lower casing 230 may also function as a single vibrating member, so that an unintended number of vibrations may occur. The upper tape 242 and the lower tape 243 of the soft material allow the vibrator 210 to vibrate independently. For the same purpose, each of the upper tape 242 and the lower tape 243 may have a thickness of 0.2 mm in order to perform a sufficient damping action against the vibration. In addition, the sufficient thickness of 0.2 mm also prevents an occurrence of short by a contact of the vibrator 210 to the upper casing 220 or the lower casing 230 by the vibration thereof or by a flow of an unintended current from the upper casing 220 or the lower casing 230 to the vibrator 210.
The upper casing 220 and the lower casing 230 may be made of a rigid material for protection of the vibrator 210. Representatively, the upper casing 220 and the lower casing 230 may contain STS. When the upper casing 220 and the lower casing 230 are made of the STS, the mosquito repellent apparatus 200 may be implemented with a smaller thickness than that with the upper casing 220 and the lower casing 230 made of a PC injection product, thereby reducing an overall thickness of the rear cover 103.
The planar portion 232 may include an inner planar portion 2321 inward of the protruding portion 231 supporting the outer peripheral region of the rear face 2102 of the vibrator 210, and an outer planar portion 2322 outward of the protruding portion 231. The inner planar portion 2321 serves to secure a distance from the vibrator 210 described above, and the outer planar portion 2322 serves as a region extended from the inner planar portion 2321. Accordingly, the outer planar portion 2232 may form the same face as the inner planar portion 2321. The outer planar portion 2322 serves as a counterpart for coupling when the mosquito repellent apparatus 200 is coupled with another apparatus to be described later.
A third face 2203 of the upper casing 220 forms a step from the second face 2202 of the upper casing 220 to be in contact with one region of the planar portion 232 of the lower casing 230, that is, the outer planar portion 2322.
The third face 2203 of the upper casing 220 may be in contact with the outer planar portion 2322 of the lower casing 230 to form the coupling counterpart. A screw hole may be defined at at least one point of the third face 2203 and the outer planar portion 2322 in contact with each other, so that the upper casing 220 and the lower casing 230 may be coupled with each other by screw coupling. For convenience of description, the screw holes defined in the planar portion 232 and the third face 2203 are defined as first screw holes 222 and 233.
The outer planar portion 2322 and the third face 2203 are provided to be in contact with each other to minimize unnecessary volume increase.
When the vibrator 210, the upper casing 220, and the lower casing 230 have circular shapes, the third face 2203 of the upper casing 220 and the outer planar portion 2322 of the lower casing 230 may have donut shapes. In this connection, each of the first screw holes 222 and 233 may include four holes positioned at four points on a donut-shaped plane and spaced apart from each other. Each of the first screw holes 222 and 233 including the four holes spaced apart from each other on the donut-shaped plane may form a stable structure.
The structure of the upper casing 220 and the lower casing 230 may have a specific shape by a stamping process. That is, the upper casing 220 forms each of the steps between the first face 2201, the second face 2202, and the third face 2203 by the stamping process on a parent member of a flat plate layer, and simultaneously define the first multi-holes 221. In addition, the protruding portion 231 may be protruded from the lower casing 230 by the stamping process on the parent member of the flat plate layer.
The first screw holes 222 and 233 may also be defined through the stamping process.
A blocking film 251 is disposed on the rear face of the lower casing 230 to prevent inflow of dust and the like from the outside.
The mosquito repellent apparatus 200 may operate alone, or as described above, may be coupled to the apparatus that performs another function, for example, the mobile terminal 100 that performs the mobile function to perform a function. In this case, the present disclosure may be largely divided into two embodiments based on arrangements of the mosquito repellent apparatus 200.
The mosquito repellent apparatus 200 may be disposed on the rear cover 103 of the mobile terminal 100. The rear cover 103 refers to a cover disposed at the rearmost portion for covering the battery in the mobile terminal 100 with the removable battery structure as described above. Because the rear cover 103 is able to be detachably coupled to the rear faces of the frames 101 and 102, the rear cover 103 may be replaced with another rear cover 103 when it is necessary. Thus, when the mosquito repellent apparatus 200 is disposed on the rear cover 103, there is an advantage in that the mosquito repellent apparatus 200 may be attached to or removed from the mobile terminal 100 as necessary.
The mosquito repellent apparatus 200 may be coupled to an inner face of the rear cover 103. At least one region of the rear cover 103 may have rearwardly protruding shape for disposing the mosquito repellent apparatus 200 thereon. Said one region is defined as an extended region 1031.
For example, the extended region 1031 may mean a bottom half region of the rear cover 103 as in the embodiment of the mobile terminal 100 of
When the bottom half region becomes the extended region 1031 as in the embodiment of the mobile terminal 100 of
On the other hand, as shown in
Hereinafter, a description will be achieved based on the shape of the mobile terminal 100 of
A seating portion 1032 for defining a region in which the mosquito repellent apparatus 200 is seated may be defined in one region of the inner face of the rear cover 103 corresponding to the extended region 1031. In particular, the upper casing 220 may be seated in the seating portion 1032 such that the face of the upper casing 220 of the mosquito repellent apparatus 200 faces the inner face of the rear cover 103.
The mosquito repellent apparatus 200 may be screwed to the seating portion 1032 of the rear cover 103. A second screw hole 1033 corresponding to the positions of the first screw holes 222 and 233 described above may be defined in the rear cover 103.
An outlet portion may be defined in the seating portion 1032 to define second multi-holes 1034 corresponding to the first multi-holes 221 therein. The number of holes of the first multi-holes 221 may be the same as the number of holes of the second multi-holes 1034. This is to minimize blockage of the high frequency emitted from the first multi-holes 221 by the rear cover 103.
However, hole shapes of the first multi-holes 221 and the second multi-holes 1034 do not need to be completely coincident with each other. For example, each of the first multi-holes 221 may be formed in a circular shape, and each hole of the second multi-holes 1034 may be formed in a triangular shape.
A pad 261 may be disposed between a mosquito repellent module and the seating portion 1032. The pad 261 may be made of a thin mesh material to block foreign substances from entering the mosquito repellent apparatus 200 from the outside and simultaneously to allow the high frequency to pass therethrough.
A region other than the seating portion 1032 of the inner face of the protruding region defines a recessed portion that is a recessed region. When the recessed portion is defined simply, as the rear cover 103 is pressed from the outside, the recessed portion may be pressed or bent, which may cause damage to the mosquito repellent apparatus 200 or the rear cover 103.
The ribs 1035 are formed on an inner face of the recessed portion to secure a rigidity of the rear cover 103. The ribs 1035 may form a lattice pattern on the inner face of the recessed portion.
The flexible printed circuit board 213 may be drawn out between the upper casing 220 and the lower casing 230, so that a terminal of one region of the flexible printed circuit board 213 may be exposed to the inner face of the rear cover 103. The terminal of one region of the flexible printed circuit board 213 exposed to the inner face of the rear cover 103 may be electrically connected to a terminal disposed on the frame rear face in a state in which the rear cover 103 is coupled to the frame, thereby performing a function of generating the high frequency.
The seating portion 1032 of the rear cover 103 may include a first bracket 10351 for supporting the first face 2201 of the mosquito repellent apparatus 200, a second bracket 10352 for supporting the second face 2202, and a third bracket 10353 for supporting the third face 2203. The first bracket 10351, the second bracket 10352, and the third bracket 10353 may protrude from the inner face of the rear cover 103 to support the upper casing 220. In particular, the pad 261 described above may perform a role of the first bracket 10351 instead of the first bracket 10351.
The third bracket 10353 supports the third face 2203, and at the same time, secures a space in which the second screw hole 1033 is defined. The second screw hole 1033 may be integrally defined with the rear cover 103 in a manner such as injection or the like when forming the rear cover 103, or may be coupled to the rear cover 103 by forming a separate additional member as shown.
The outer planar portion 2232 of the lower casing 230 forms the same plane as the inner planar portion 2321, so that the third face 2203 is disposed to be biased to the lower casing 230 as much as possible, thereby securing a space in which a thread of the second screw hole 1033 is disposed.
The second bracket 10352 and the third bracket 10353 may be arranged as a portion of the region in which the ribs 1035 described above are arranged. That is, the second bracket 10352 and the third bracket 10353 have lengths different from a length of the ribs 1035 described above, but have the same pattern as the ribs 1035, thereby serving as the ribs 1035.
As in the previous embodiment, the screw 245 may fix the upper casing 220 and the lower casing 230 to the rear cover 103, but may fix only between the upper casing 220 and the rear cover 103 to minimize a coupling thickness of the mosquito repellent apparatus 200 and the rear cover 103. When the first screw hole 233 of the lower casing 230 is formed larger than a screw head 2452, the screw head 2452 may be seated inside the first screw hole 233 of the lower casing 230 to minimize the increase in thickness.
The embodiments of the mobile terminal 100 of
The rear frame refers to a frame coupled to the rear face of the front frame as described above. The coupling of the front frame and the rear frame may define an electronic component portion between the front frame and the rear frame, so that main electronic components such as a main-PCB and the like may be mounted in the electronic component portion. In some cases, without classification of the front frame and the rear frame, the frames may be formed as a single frame on which the display unit is seated and forming the electronic component portion. The present embodiment will be described on the premise that the rear cover 103 is disposed on the rear face of the rear frame.
In the embodiments of the mobile terminal 100 of
The embodiment of the mobile terminal 100 of
The rear frame is coupled to the rear face of the front frame to define the electronic component portion of the mobile terminal 100 therebetween. The main-printed circuit board (main-PCB) for mounting electronic components thereon may be disposed inside the rear frame.
In the present embodiment, the mosquito repellent apparatus 200 may be mounted on a rear face of the main PCB.
The rear frame may define an opening 1021 for exposing the mosquito repellent apparatus 200 to the outside. The mosquito repellent apparatus 200 may be coupled with the rear frame instead of the main PCB to prevent damage to the main PCB during the coupling process. The rear frame has a third screw hole 1022 at a point corresponding to the first screw holes 222 and 233 of the mosquito repellent apparatus 200 on the inner face thereof. Further, the first screw holes 222 and 233 and the third screw hole 1022 may be fastened with each other by the screw 245.
It is apparent to those skilled in the art that the present disclosure may be embodied in other specific forms without departing from the spirit and essential characteristics of the present disclosure.
The above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the present disclosure should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present disclosure are included in the scope of the present disclosure.
As described above, all or some of the features of the present disclosure may be used in any mosquito repellent apparatus or mobile terminal.
