DETAILED DESCRIPTION OF THE INVENTION
The preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a mobile terminal 1 according to a first embodiment of the present invention. FIG. 2 is a side view of the mobile terminal 1 according to the first embodiment of the present invention. FIG. 3 is a view showing an operational state of the mobile terminal 1 according to the first embodiment of the present invention.
The mobile terminal 1 includes a first body 10 having a display 12 for displaying various information and a speaker 14 for outputting sound. A second body 20 is mounted at the first body 10 such that the second body can be slidably moved and has a keypad 24 with key buttons 22 formed on its front surface for allowing a user to input information and a battery 26 mounted at a rear surface. A fragrance emanating unit 30 is disposed at a position on at least the first body 10 or the second body 20 that is near the nose 40 of a user when the user performs call communication. A slide module 16 is installed between the first body 10 and second body 20 and facilitates the first body 10 sliding over the second body 20.
The second body 20 also includes a microphone 28 for receiving the user's voice during call communication. The keypad 24 can be integrally formed with the case of the second body 20 in order to have a key button region or the keypad can have push-type key buttons and be mounted on an upper surface of the case of the second body 20.
As illustrated in FIGS. 1-3, the fragrance emanating unit 30 is mounted at one side of the second body 20 which is close to the nose 40 of the user when the user slides the first body 10 in an opening direction and places the mobile terminal to his or her face for call communication. Because the fragrance emanating unit 30 is positioned such that it is close to the user's nose during call communication, the user can smell fragrance emanated from the fragrance emanating unit 30 effectively.
The fragrance emanating unit 30 can be attached on one side of the keypad 24 disposed on the second body 20 or can be integrally formed with the keypad 24 and have a pad containing a material capable of emanating fragrance or a pad including a fragrance emanating capsule. The fragrance emanating unit 30 can be mounted at a location on the front surface of the case of the second body 20, other than on the keypad 24, or can be insertedly disposed in a groove formed on the front surface of the case of the second body 20.
The fragrance emanating unit 30 can be positioned at any position as long as it is close to the user's nose when the user puts the mobile terminal near his or her face to perform call communication after sliding the first body 10 in the opening direction. Preferably, the fragrance emanating unit 30 is positioned at a midpoint between the left and right sides of the second body 20. Furthermore, the fragrance emanating unit 30 can be installed such that it is exposed either partially or entirely when the first body 10 is slid in the opening direction.
Specifically, the fragrance emanating unit 30 can be installed at the center of an upper side of the second body 20 such that when the first body 10 is slidably moved in a closing direction, the fragrance emanating unit is covered by the first body, and when the first body 10 is slidably moved in the opening direction, a portion of the fragrance emanating unit 30 is exposed to emanate fragrance. The fragrance emanating unit 30 is formed as a semi-circular pad such that it can be fixedly attached on the front surface of the keypad 24 or mounted in a groove formed on the upper surface of the case of the second body 24.
The fragrance emanating unit 30 can be detachably mounted on the second body 20 so that it can be replaced when completely used up. Specifically, the fragrance emanating unit 30 can be changed through an attachment/detachment process, and has a form that facilitates easy replacement. Any structure that facilitates replacement of the fragrance emanating unit 30 may be utilized.
In the mobile terminal according to the first embodiment, when the first body 10 is slid in the opening direction, the fragrance emanating unit 30 is exposed. When a user puts the mobile terminal near his or her face to perform call communication, the fragrance emanating unit 30 is near the user's nose, thereby allowing the user to smell the fragrance emanated from the fragrance emanating unit effectively.
FIG. 4 is a perspective view of a mobile terminal 100 according to a second embodiment of the present invention. As illustrated in FIG. 4, a fragrance emanating unit 130 is formed as a band in a widthwise direction of the second body 120. Specifically, the fragrance emanating unit 130 is disposed in the widthwise direction of the keypad 24 mounted on the second body 120 or on an upper surface of the case of the second body that is close to the user's nose during call communication.
Similar to the fragrance emanating unit 30 in the first embodiment of the present invention, the fragrance emanating unit 130 of the second embodiment of the present invention has a pad and can be detachably mounted on the second body such that the fragrance emanating unit is replaceable. Because the fragrance emanating unit 130 is mounted in the widthwise direction of the second body 120, a minimum distance can be maintained between the fragrance emanating unit and the user's nose when the user puts the mobile terminal close to his or her face for call communication even when the position of the mobile terminal 100 is changed.
FIG. 5 is a perspective view of a mobile terminal 200 according to a third embodiment of the present invention. As illustrated in FIG. 5, the mobile terminal includes a fragrance emanating unit 230 mounted at a bottom edge of the first body 210.
In the third embodiment of the present invention, the fragrance emanating unit 230 is mounted at a bottom edge of the first body 210 in the widthwise direction. The bottom edge is near a user's nose 40 when the first body is moved in the opening direction for call communication. A groove 232 is formed in the widthwise direction at the lower edge of the first body 210 and the fragrance emanating unit 230 is inserted in the groove. In this way, the fragrance emanating unit 230 can be detachably mounted in the groove 232.
FIG. 6 is a perspective view of a mobile terminal 300 according to a fourth embodiment of the present invention. FIG. 7 is a sectional view of the mobile terminal 300 according to the fourth embodiment of the present invention. FIG. 8 is a perspective view of a second body 320 of the mobile terminal 300 according to the fourth embodiment of the present invention. FIG. 9 is a view showing an operational state of the mobile terminal 300 according to the fourth embodiment of the present invention.
As illustrated in FIG. 6, a fragrance emanating unit 330 is mounted on the second body 320 such that it is near a user's nose 40 during call communication. When the first body 10 is slid in the opening direction, the fragrance emanating unit 330 emanates fragrance. The fragrance emanating unit 330 may also be provided on the first body 10, either in addition to or in place of the fragrance emanating unit provided on the second body 320.
The fragrance emanating unit 330 includes a sealing member 332 fixed on the keypad 24 on the upper surface of the second body 320 and is sealed when the mobile terminal 300 is in a closed state and is partially exposed when the mobile terminal is in an opened state. A fragrance emanating member 334 is received inside the sealing member 332 and emanates fragrance.
Preferably, the sealing member 332 has a space portion 336 therein, a circumferential surface protruded with a certain height and is formed in a container with its upper surface open. Preferably, the sealing member 332 is made of an elastic rubber material so that when the first body 10 is closed, the upper surface of the sealing member is attached to the lower surface of the first body 10 to thereby seal the interior of the fragrance emanating unit 330.
In this way, when the first body 10 is in the closed state, the upper surface of the sealing member 332 is tightly attached to the lower surface of the first body 10 to seal the interior of the sealing member. When the first body 10 is slid in the opening direction, a portion of the interior of the sealing member 332 is exposed.
Preferably, the fragrance emanating member 334 is formed as a pad including a fragrance generating capsule. The fragrance emanating member 334 may have any form, such as the pad or a gel, as long as it can emanate fragrance.
When the first body 10 is in a closed state, the upper surface of the sealing member 332 is tightly attached to the upper surface of the first body 10 such that the fragrance emanating in unit 330 is sealed. Accordingly, the fragrance emanating member 332 received inside the sealing member 332 is in a sealed state in order to prevent fragrance from emanating.
When the first body 10 is opened to use the mobile terminal, the first body 10 is slid over the second body 320 and a portion of the sealing member 332 that is fixed on the second body is exposed. In this state, when a user puts the mobile terminal 300 near his or her face, the fragrance emanating member 334 is close to the user's nose 40, thereby emanating fragrance such that the user can small the fragrance effectively.
When the mobile terminal 300 is in the closed state, the fragrance emanating member 334 is sealed by the sealing member 332 to prevent fragrance from being emanated externally. When the mobile terminal 300 is opened, the fragrance emanating member 334 is exposed to emanate fragrance externally.
Although described with respect to a slide type mobile terminal, the present invention may be applied to other types of mobile terminals. The fragrance emanating unit described above is also applicable to a folder type or a swing type mobile terminal.
Specifically, in a folder type mobile terminal, the fragrance emanating unit can be positioned on a portion of the terminal body that is close to a user's nose when the user opens the folder by rotating it about a hinge connection portion and puts it near his or her ear. One of the key buttons of a keypad mounted on the terminal body, such as a key button positioned on a portion of the keypad that is close to the user's nose when the mobile terminal is used, can be replaced with the fragrance emanating unit. Likewise, in a swing type mobile terminal where a first body is rotated in a swinging manner over a second body, the fragrance emanating unit can be positioned on a certain portion of the first body or the second body that is close to the user's nose when the user opens the first body in the swinging manner and puts it to his or her ear.
The mobile terminal according to the present invention has many advantages. When a user puts the mobile terminal near his or her face for call communication, the fragrance emanating unit is close to the user's nose such that the user can effectively smell the fragrance during call communication. Additionally, when the first body is in the closed state, the fragrance emanating member is prevented from emanating fragrance externally and when the first body is opened, the fragrance emanating member is partially exposed to emanate fragrance externally, thereby reducing waste of the fragrance emanating material and extending the period during which fragrance is emanated from the mobile terminal.
The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses.
The description of the present invention is intended to be illustrative and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. In the claims, means-plus-function clauses are intended to cover the structure described herein as performing the recited function and not only structural equivalents but also equivalent structures.
