PREFERRED EMBODIMENTS OF THE INVENTION
To make objectives, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail hereinafter with combination of the accompanying drawings. It should be noted that, in case of no conflict, the embodiments and features of the embodiments in the present application could be combined randomly with each other.
The handwriting pen provided in the present invention is applicable to mobile terminals such as mobile phones, and this embodiment will be described by taking the mobile phone as an example, and it should be noted that the handwriting pen in the present invention is not limited to the application in mobile phones.
As shown in FIG. 1, a mobile terminal handwriting pen in accordance with an embodiment of the present invention comprises: pen nib 1, pen body 2 and pen cap 3. Wherein, said pen nib 1 is used to write on a touch screen, and said pen body 2 is easy to be held by a user, and said pen cap 3 is used to enclose said pen body 2 and for the beautiful appearance of the handwriting pen.
Said pen nib 1 is the earphone plug 5. The audio can be obtained through the earphone plug 5, the outer layer of the earphone plug 5 is metal, and it can be directly used as said pen nib 1 of the handwriting pen, that is, the earphone plug 5 can be used directly to perform handwriting input on the mobile phone touch screen.
One end of said pen body 2 is fixedly connected with said pen nib 1, and the other end is movably connected with said pen cap 3. The length and thickness of the pen body 2 are designed to be easily grabbed and carried. The shape of said pen body 2 is generally cylindrical, polygonal columnar and so on, and the material of said pen body 2 can be metal or plastic. Said pen body 2 is provided with earphone cord 4, both ends of which are respectively connected with said earphone plug 5 and earplug 6. The length of said earphone cord 4 is greater than the length of said pen body 2, and said earphone cord 4 can be wrapped and stored inside said pen body 2, and can be pulled out when used.
Said pen cap 3 movably cooperate and connect with said pen body 2, and it can be integrated with said pen body 2 and can also be easily removed from said pen body 2 and used alone. Said earplug 6 is disposed on said ear cap 3 and is the same as other earplugs in order to be fit into a human ear. A connection structure is set on said earplug 6 to facilitate the quick connection with said pen body 2.
In the embodiment of the present invention, said pen nib 1 is the earphone plug 5, said earplug 6 is disposed on said pen cap 3, and said earphone cord 4 is provided inside said pen body 2, which can achieve not only the mobile phone handwriting pen function, but also the earphone function, and it is easy to be carried and has a simple structure, which does not increase the phone's production costs and has beautiful appearance.
