1. Field of the Disclosure
The present invention relates to a capacitive type stylus with easy storage and portability and a mobile terminal including the same, more particularly, to a capacitive type stylus that is wearable on a user's body part for easy storage and portability even as a fashion item, and a mobile terminal including the capacitive type stylus.
2. Discussion of the Related Art
A mobile terminal is a device which may be configured to perform various functions. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files and outputting music via a speaker system, and displaying images and video on a display. Some terminals include additional functionality which supports game playing, while other terminals are also configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of contents, such as videos and television programs.
Generally, terminals can be classified into mobile terminals and stationary terminals according to their degree (e.g., ease) of mobility. Further, the mobile terminals can be further classified into handheld terminals and vehicle mount terminals according to the manner of portability.
Such a mobile terminal may be operated via a touchscreen and the functions mentioned above may be implemented on a touchscreen. A user has one of the fingers or an auxiliary pen contacting with the touchscreen to operate the mobile terminal. Such an auxiliary stylus may enable more sensitive operation, compared with the finger, and the auxiliary stylus can be provided in the mobile terminal as an accessory or mounted in the mobile terminal.
However, the stylus provided as an accessory is difficult to carry, with a high risk of loss. The stylus mounted in the mobile terminal may occupy a predetermined space that reduces the mounting space for the other parts. Also, the space for the stylus makes the mobile terminal thick. If a diameter of the stylus is reduced to reduce the space occupied by the stylus, it might be uncomfortable for the user to hold such a stylus and usability might deteriorate. Touch input of a conventional stylus might fail to be recognized even when touch is implemented.
Moreover, such the captive type stylus has technical restriction and simply monotonous design, only to disadvantageously fail to reflect users' personalities or sensitivities.

As shown in
The body 210 is made of a conductive material to pass electric currents there through. The body 210 elastically deforms and it can maintain the deformed appearance until forced otherwise. For example, the body 210 may be made of one metal and such a metal can be deformed by a force applied by a user. Even without the force applied by the user, the deformed shape of the body 210 can be maintained. When the user holds the body 210 to use the stylus, the body 210 collects a static electricity from the user's body and the static electricity is transferred to the pen tip 300.
As shown in
In other words, the body 210 according to this embodiment is kept in a straight metal strip as shown in
As shown in
The connecting portion 320 is made of a metal and it is extended in a longitudinal direction. For example, the connecting portion 320 is formed in a cylindrical shape having a partially variable diameter along a longitudinal direction. An end of the connecting portion 320 is connected to the end of the body 210 and the contacting portion 310 is provided in the other end of the connecting portion 320. As the connecting portion 320 is made of a metal, the static electricity of the human body transferred to the body 210 may be transferred to the pen tip 300. Preferably, the diameter of the connecting portion 320 may be larger than the thickness of the body 210. In this instance, an area of the contacting portion 310 contacting with a touchpad can be enlarged to operate the capacitive type stylus more stably.
In one embodiment, the connecting portion 320 may be independently with respect to the body 210 and it may be connected to the end of the body 210 after that. In this instance, the metal used in forming the connecting portion 320 may be different from the metal used in forming the body 210.
In another embodiment, the connecting portion 320 may be integrally connected to the body 210. According to this embodiment, the connecting portion 320 is molded together with the body 210 to be longitudinally projected from the end of the body 210. In this instance, the connecting portion 320 and the body 210 may be made of the same metal. When the connecting portion 320 is projected from the end of the body 210 configured of the metal strip, the contacting portion 310 covers an end of the connecting portion 320 to form the pen tip 300.
The contacting portion 310 is made of a conductive and elastic material and it covers the other end of the connecting portion 320. For example, such a conductive material having elasticity may include conductive silicon, conductive rubber and the like. The contacting portion 310 can contact with the touch pad provided in the mobile terminal to implement input to the mobile terminal. The display provided in the mobile terminal and the touch pad are configured to form a mutual layer structure to form a touchscreen. The contacting portion 310 can contact with the touchscreen.
When the static electricity of the human body is transferred to the contacting portion 310 via the body 210, a static electricity is also generated in the contacting portion 310. When the static electricity generated in the contacting portion 310 is a predetermined minim electrostatic capacitance or more, a magnetic field of the touch pad contacting with the contacting portion 310 is changed to allow the touch pad to recognize the touch as an input signal. In other words, to enable the capacitive type stylus to operate, the contacting portion 310 of the pen tip 300 has to transfer the static electricity with the minimum capacitance or more to the touch pad. At this time, the electromagnetic capacitance transmitted from the contacting portion 310 is determined by a contact area of the contacting portion 310 with the touch pad. The size of the contact area (hereinafter, referred to as ‘a necessary contact area’) corresponding to the size of the minimum capacitance with respect to the touch pad may be set differently based on the configuration and function of the touch pad.
As shown in
Meanwhile, the connecting portion 320 is projected form a rear end of the contacting portion 310 and it is connected to the end of the body 210. The connection between the connecting portion 320 and the body 210 may enable the pen tip 300 connected to the end of the body 210. Also, the connecting portion 320 may be made of a conductive material. In this instance, the human static electricity collected via the body 210 may be transmitted to the contacting portion 310 via the connecting portion 320. In one embodiment, the connecting portion 320 may be integrally connected to the contacting portion 310.
According to the present invention, the body capable of maintaining the deformed shape after the bending deformation may deform the shape of the stylus. The user straightens the body 210 to use the stylus as a pen. In case of not using the stylus, the user rolls the body 210 to wear the stylus on the wrist 10. Accordingly, the user can carry and keep the stylus conveniently and easily even without putting it in a bag separately. Also, the user can wear it on one of body parts and prevent risks of loss.
In one embodiment, the capacitive type stylus as shown in
The cover 220 may be conductive or non-conductive. Even in case it is made of a non-conductive material, the cover 220 is formed thin. When the user is holding the body 210 covered by the cover 220, the human static electricity traverses the thin cover 220 and reaches the body 210. As shown in
The cover can be made of such various materials to have various colors and textures, such that the user may select a color and a texture according to his or her taste. Accordingly, the user can wear the stylus so that his or her personality is reflected therein and utilize it as a fashion item.
The main configuration of the capacitive type stylus according to the present invention is described above. Referring to
In one embodiment, the end of the body 210 is inserted in the connecting portion 320 of the pen tip 300 as shown in
The width of the inserting groove 3210 formed in the connecting portion 320 may be the same as or smaller than the thickness of the body 210. When the width of the inserting groove 3210 is smaller than the thickness of the body 210, the connecting portion 320 and the body 210 may be forcibly coupled to each other in inserting the end of the body 210 in the connecting portion 320. Accordingly, the pen tip 300 may be fixed to the body firmly.
Optionally, before the end of the body 210 is inserted in the inserting groove 3210, an adhesive may be applied to at least one of an inner surface of the inserting groove 3210 and the end of the body 210. When the body 210 is inserted in the inserting groove 3210, with the adhesive applied thereto, the pen tip 300 can be effectively fixed to the body 210 by the adhesion of the adhesive.
In another embodiment, the pen tip 300 may be detachably coupled to the body 210. In this instance, the connecting portion 320 of the pen tip 300 and the body 210 are not connected with each other by using the forcible coupling or the adhesive. There may be provided a plurality of pen tips 300 including contacting portions 310 with different diameters or shapes with respect to one body 210, respectively.
One of examples, as shown in

As shown in
To make the stylus operated in a capacitive way, the pen tip 300 has to the static electricity having a predetermined capacitance or more to a touch pad. The electrostatic capacitance transferred from the pen tip 300 may be determined based on a contact area between the pen tip 300 and the touch pad. To satisfy the minimum contact area for the electrostatic capacitance, an end of the pen tip 300 may has a blunt shape as shown in
Referring to
As shown in
For example, the metal cable 212 defining the body 210 may be configured of a cobra-pipe shown in
In this embodiment, a cover 220 having various colors and textures covers the body 210 configured of the metal cable 212. As mentioned above, even when the cover 220 is non-conductive, the human static electricity may be transferred to the body 210 via the cover 220 and the user may express his or her personality via the various-colored and textured cover 200.
As shown in
When the body 210 of the stylus is configured of the metal cable 212, it is preferred that a plurality of metal cables 212 may be provided. Both ends of two or more metal cables 212 are fixed to first and second supporting portions 230 and 240, respectively, to arrange the two or more metal cables 212 in parallel. After that, the metal cables 212 repeat bending deformation several times, to prevent entanglement. Accordingly, the body 210 of the stylus may not be distorted even if the user repeats usage and storage of the stylus and the durability and usability of the stylus can be enhanced.
In one embodiment, the capacitive stylus according to the third embodiment may further include a length adjusting module 600 provided in the second supporting portion 240. Not to interfere with the pen tip 300, the length adjusting module 600 may be provided in the second supporting portion 240 not connected with the pen tip 300, out of the first and second supporting portions 230 and 240 connected to both ends of each metal cable 212. The length adjusting module 600 provided in the second supporting portion 240 may be extendible longitudinally to adjust the overall length of the stylus.
As the overall length of the stylus is adjustable by the length adjusting module 600, the stylus can be worn by the user on a body part, regardless of the user's body size. For example, in case the user is an adult male having a relatively large body size, the length adjusting module 600 extends the overall length of the stylus to make him or her wearing the stylus comfortably. In case the user is a child having a relatively small body size, the length adjusting module 600 may reduce the overall length of the stylus.
Specifically, as shown in
The insert screw 620 and the adjusting screw 610 may engage with each other to allow the adjusting screw 610 to move in a longitudinal direction of the body 210 while rotating in communication with the insert screw 620. For that, a screw thread formed in an outer peripheral surface of the insert screw 620 may be spiral to engage with a screw thread of the adjusting screw 210. As shown in
As shown in an arrow of
In another embodiment, the capacitive type stylus according to the third embodiment may further include a battery 510 mounted in the body 210 of the stylus, and a display module 520 formed in the body 210 of the stylus to output an image when receiving the electric power, as shown in
The battery 510 may be mounted in either of the first and second supporting portions 230 and 240 and it may supply the electric power to the stylus. The display module 520 may be formed in the other one of the first and second supporting portions 230 and 240 where the battery 510 is not mounted. The battery 510 and the display module 520 are provided in different positions, such that the sizes of the first and second supporting portions 230 and 240 may be reduced as much as possible to make the stylus maintain a slim shape.
The display module 520 formed in opposite to the battery 510 to be supplied the electric power of the battery 510 via one or more conductive metal cable 212 defining the body 210. For that, an end of the metal cable 212 may be connected to the battery 510 and the other end of the metal cable 212 may be connected to a PCB configured to drive the display module 520. In one embodiment, the display module 520 may be configured of an organic light emitting diode and it may be driven with a low electric power accordingly.
The usability of the capacitive type stylus can be enhanced by the display module 520 formed in the body 210. For example, the display module 520 outputs an image of an electronic watch and the capacitive type stylus can be used as an electronic watch. Optionally, the display module 520 outputs images including various photographs and it can be used as a tool for expressing the user's personality and sensitivity.
The body and the pen tip that compose the capacitive type stylus according to the first to third embodiments of the present invention are described above. Next, referring to
As shown in
The components will be sequentially described as follows.
The short-range communication module 230 facilitates relatively short-range communications with a mobile terminal in a short-range. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few. Specifically, the short-range communication module 230 communicates with an auxiliary short-range communication module (114, see
As the short-range communication module 230 is provided, the capacitive type stylus can be operated in communication with the mobile terminal. When the capacitive type stylus is in communication with the mobile terminal, the operation of the mobile terminal can be controlled by using the capacitive type stylus. Also, the operation of the stylus can be controlled by using the mobile terminal. As a result, the usage range of the capacitive type stylus is enlarged remarkably.
The sensing unit generates electric signals and relating data for sensing status measurements of various aspects of the user wearing the capacitive type stylus. The generated electric signals and data may be transmitted to the control module 240. The control module 240 receiving the electric signal or data may control the other components of the capacitive type stylus based on the electric signal or data, or control the electric signal or data transmitted to the case of the mobile terminal. The case of the mobile terminal may control the operations of the mobile terminal based on the electric signal or data.
Specifically, the sensing unit may include at least one of a first sensor 251 for sensing motion of the body, a second sensor 252 for sensing deformation of the body and a third sensor for sensing body motion made by the user wearing the capacitive type stylus.
The first sensor 151 may be mounted in the body of the capacitive type stylus and it may convert the sensed motion of the body into an electric signal. The motion of the body may include the translation performed by the body in up-and-down/right-and-left directions and the rotation of the body. Optionally, the motion of the body may include a case where those translation and rotation are performed simultaneously. For example, the first sensor 251 may detect the motion of the body rotating on a center space in a bent state. Also, the first sensor 251 may detect the motion of the body in the direction the force of gravity activates or in the reverse direction. The first sensor 251 may include a Gyro sensor, an acceleration sensor, a gravity sensor and a motion recognition sensor including a geo-magnetic sensor.
The second sensor 252 may be mounted in the body of the capacitive type stylus and it may convert a bent or straightened state of the body into an electric signal. As mentioned above, the body of the capacitive type stylus according to the present invention has the convex portion deformed concavely to be rolled. The user applies a force to the rolled body to change the concavely deformed surface into a convex portion again and then the body is straightened. In other words, the body of the capacitive type stylus may have two shapes configured of the bent state or the linearly straightened state. The second sensor 252 may detect the bent state of the body and the linearly straightened state of the body. For example, the second sensor 252 may include a flex sensor (or a bending sensor) attached to the body to be bent together when the body is rolled to covert a bending level into an electric signal.
The third sensor 253 may be mounted in the body of the capacitive type stylus to collect biometric information on a person contacting with the body. As mentioned above, the body of the capacitive type stylus has a deformable shape that can be rolled curvedly such that the user may wear the stylus on the wrist 10 like a bracelet. When the user puts on the body on the wrist 10, biometric information on the user may be directly transmitted to the body and the third sensor 253 may collect the biometric information. The biometric information may include Electrocardiogram (ECG), a heart rate per minute, a pulse rate and a temperature. The third sensor 253 may measure such the biometric information at preset regular intervals and it may generate biometric information data based on the collected biometric information.
The display module 520 may be formed in a surface of the body and it may output the information processed in the control module 240 of the capacitive type stylus or transmitted from the case of the mobile terminal. For example, the display module 520 may output user interface (UI) provided with input of a command by the user via touch input. The display module 520 may output information associated with data on a call signal, a message and a social network service (SNS) transmitted to the case of the mobile terminal.
The display module 520 may be configured of an organic light emitting diode (OLED) or a flexible display. In this instance, the shape of the display module formed in the surface of the body can be deformed and the body can be curvedly rolled or linearly straightened with no interference of the display module 520.
Optionally, the display module 520 may be configured of a touchscreen. For that, the display module 520 and the touch pad may form a mutual layered structure or they may be integrally formed with each other as one body. In case the display module 520 is configured of a touchscreen, the display module 520 detects and coverts a touch input implemented on the display module 520 by the user into an electric signal. The electric signal may be transmitted to the control module 240 and the control module 240 may control the capacitive type stylus based on the electric signal or transmit the electric signal to the case of the mobile terminal.
The informing module 540 may be provided in the body of the capacitive type stylus to output a signal to inform event generation. At this time, such an event may be generated in the case of the mobile terminal. When an event is generated, the case of the mobile terminal may generate and transmit an electric signal to the short-range communication module of the capacitive type stylus. When receiving the electric signal, the control module 240 may control the informing module 540 to output a signal. The signal the informing module is able to output may include all of video, audio, tactile signals. For example, the informing module 540 may include LED elements emitting specific color lights, respectively, a vibration module generating vibration and a bone conduction vibrating device for vibrating the user's bone conduction.
The control module controls the short-range communication module, the sensing unit, the display module 520 and the informing module 540, to control the general operation of the capacitive type stylus. For example, the control module 240 may control the operations of the other components based on the electric signal generated in the sensing unit. Optionally, the control module may control the short-range communication module to exchange an electric signal or data with the case of the mobile terminal or it may recognize written input implemented on the display module 520 configured of the touchscreen as letters.
The power supply unit may provide the electric power to the short-range communication module, the sensing unit, the display module 520, the informing module 540 and the control module 240 which are provided in the capacitive type stylus. For example, the power supply unit may be a rechargeable battery 510. The battery 510 may be mounted in the body of the capacitive type stylus or detachably coupled to the body. As another example, the power supply unit may be a solar cell panel 512 converting solar light into electric energy. Such a solar cell panel 512 may be provided in a surface of the body, with being electrically connected with the short-range communication module and the control module 240.

As an example, consider the mobile terminal 100 being configured as a slide-type mobile terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device.

The display 151 is typically implemented to visually display (output) information associated with the mobile terminal 100. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface (UI) or graphical user interface (GUI) which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display 151 may additionally or alternatively display images which are associated with these modes, the UI or the GUI.

The mobile terminal 100 may include one or more of such displays.
Some of the above displays can be implemented in a transparent or optical transmittive type, which can be named a transparent display. As a representative example for the transparent display, there is TOLED (transparent OLED) or the like. A rear configuration of the display 151 can be implemented in the optical transmittive type as well. In this configuration, a user is able to see an object in rear of a terminal body via the area occupied by the display 151 of the terminal body.
At least two displays 151 can be provided to the mobile terminal 100 in accordance with the implemented configuration of the mobile terminal 100. For instance, a plurality of displays can be arranged on a single face of the mobile terminal 100 in a manner of being spaced apart from each other or being built in one body. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal 100.
In case that the display 151 and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) configures a mutual layer structure (hereinafter called ‘touchscreen’), it is able to use the display 151 as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, a touchpad or the like.
The touch sensor can be configured to convert a pressure applied to a specific portion of the display 151 or a variation of a capacitance generated from a specific portion of the display 151 to an electric input signal. Moreover, it is able to configure the touch sensor to detect a pressure of a touch as well as a touched position or size.
If a touch input is made to the touch sensor, signal(s) corresponding to the touch is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 180. Therefore, the controller 180 is able to know whether a prescribed portion of the display 151 is touched.

Next, the detailed structure of the capacitive type stylus and various examples of operations performed in communication between the capacitive type stylus and the case of the mobile terminal will be described as follows, referring to
To distinguish the capacitive type stylus 200 from the components provided in the case 100 of the mobile terminal, a prefix of “first” is given to the short-range communication module provided in the case 100 of the mobile terminal. A prefix of “second” is given to the short-range communication module provided in the capacitive type stylus 200.
In other words, the short-range communication module provided in the case 100 of the mobile terminal will be referenced to as “a first short-range communication module 114” and the short-range communication module provided in the capacitive type stylus 200 will be referenced to as “a second short-range communication module 230” as follows.
As shown in
A pen tip receiving groove 410 may be formed in an end of the module box 400 coupled to the body 210 of the capacitive type stylus 200. The pen tip receiving groove 410 is recessed from the end of the module box 400 and it may have a predetermined shape and size configured to insert a contacting portion of the pen tip 300 therein. It is preferred that the end of the module box 400 where the pen tip receiving groove 410 is formed is the end in opposite to the pen tip 300 in a straightened state of the body 210 as shown in
As shown in
In this embodiment, various electronic components are mounted in the module box 400 and various functions can be provided to the capacitive type stylus 200, with no interference of the electronic parts to the deformation of the body 210. Accordingly, the capacitive type stylus 200 can be simply worn by the user on the wrist 10 and the various functions can be realized simultaneously. In addition, when the capacitive type stylus 200 is worn by the user on the wrist 10, the contacting portion of the pen tip 300 is inserted in the pen tip receiving groove 410 and the end of the body 210 may be coupled to the other end of the body. Accordingly, the capacitive type stylus 200 can be worn more stably.
As shown in
When the solar cell panel 512 is provided in the body 210, no auxiliary battery has to be provided to supply the power to the second short-range communication module 230 and the control module 240. If a battery is provided, the second short-range communication module 230 and the others can be provided with the power even without regular recharging. Accordingly, the usability of the capacitive type stylus 200 may be enhanced.
Meanwhile,
As shown in
The first sensor 251 detects and converts a specific patterned motion into an electric signal. The control module 240 of the capacitive type stylus 200 transmits the electric signal to the case 100 of the mobile terminal via the second short-range communication module 230. Hence, the first short-range communication module receives the electric signal and the controller 180 of the mobile terminal case 100 recognizes the electric signal as a user command, to implement a control command corresponding to the specific patterned motion. In a memory 160 of the mobile terminal case 100 may be stored database including various patterned motions and control commands corresponding to the various patterned motions, respectively.
For example, as shown in

The second sensor 252 detects change of the shape from the bent state into the straightened state (hereinafter, referred to as “a first shape deformation”) and change of the shape from the straightened state into the curvedly bent state (hereinafter, referred to as “a second shape deformation”). After that, the second sensor 252 converts the detected deformation into an electric signal. The control module 240 controls the second short-range communication module 230 to transmit the electric signal to the mobile terminal case 100. When the first short-range communication module 114 receives the electric signal, the controller 180 recognizes the electric signal as the user command and implements a control command corresponding to the deformed shape. As mentioned above, in the memory 160 of the mobile terminal case 100 may be stored the first shape deformation and the second shape deformation and control commands corresponding to the first and second shape deformations, respectively.

In another case, as shown in
In this embodiment, as soon as the user puts on the stylus 200 on the wrist 10 to keep the stylus 200 after completing the usage of the capacitive type stylus 200, the application implemented in the mobile terminal case 100 is completed and contents associated with the application may be stored. Accordingly, the usability of the capacitive type stylus 200 can be enhanced.
As shown in
In one embodiment, various mode screens may be displayed on the display module 520. Screen modes that can be displayed on the display module 520 may include a receiving inform mode, a clock mode and a biometric information display mode In the receiving inform mode, the display module 520 displays information associated with the mobile terminal case 100 receiving a call signal, a message and SNS in communication with another mobile terminal.

For that, the capacitive type stylus 200 may include a third sensor 253. The third sensor 253 collects the user's biometric information data and the control module 240 controls the biometric information to be displayed on the display module 520.
Optionally, the user's biometric information data collected by the third sensor 253 may be displayed on the display 151 of the mobile terminal case 100. In this instance, the control module 240 controls the second short-range communication module 230 to transmit the collected biometric information data to the mobile terminal case 100. The user may select or change whether the biometric information data is displayed on the display module 520 of the capacitive type stylus 200 or on the display 151 of the mobile terminal case 100.
The display module 520 provided in the capacitive type stylus 200 enables the user to acquire the received and transmitted information of the mobile terminal case 100, without seeing the case 100 directly. Accordingly, the inconvenience of taking out the mobile terminal whenever a call signal and a message are received can be reduced. Together with that, the display module 520 may be employed as a watch and a biometric information display. As a result, the usability of the capacitive type stylus and the mobile terminal may be enhanced.
As shown in
For example, as shown in
In this embodiment, the display module 520 may be configured of a touchscreen. The display module 520 detects touch input on the touchscreen and converts the detected touch input into an electric signal. After that, it may transmit the converted electric signal to the control module 240. The control module 240 may control the second short-range communication module 230 to transmit the electric signal to the mobile terminal case 100 when detecting the touch input on the touchscreen. When the mobile terminal case 100 receives the electric signal, the controller 180 of the mobile terminal case 100 implements a command corresponding to the electric signal and controls the mobile terminal according to the touch inputted on the touchscreen.

As another example, as shown in
As a further example, the informing module 540 maybe a bone conduction vibration device. Such a bone conduction vibration device vibrates the bone possessed by the user contacting with the body 210 to make him or her to hear a sound. When the mobile terminal receives the message, the electric signal is transmitted to the capacitive type stylus 200 and the bone conduction vibration device may output vibration. If the user is wearing the capacitive type stylus 200 on the wrist 10 for storage, the vibration of the bone conduction vibration device vibrates the user's bone to make the user hear an informing sound. In this instance, the informing sound cam be transmitted to the user's ears effectively, compared with the informing sound transmitted through the air. Accordingly, definite informing may be enabled and such the informing sound is not heard by the other people not wearing the capacitive type stylus 200 only to enhance convenience.
According to this embodiment, the user can be effectively informed via the capacitive type stylus 200 whether the mobile terminal receives a call signal or message. Accordingly, even if storing the mobile terminal case 100 in another space, the user can make response to a call signal or message without missing.
In addition, the above-described methods can be implemented in a program recorded medium as computer-readable codes. The computer-readable media include all kinds of recording devices in which data readable by a computer system are stored. The computer-readable media include ROM, RAM, CD-ROM, magnetic tapes, floppy discs, optical data storage devices, and the like for example and also include carrier-wave type implementations (e.g., transmission via Internet). And, the computer can include the control unit 180 of the terminal.
