Description:
CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    The present application claims and enjoys a priority of the Chinese patent application No. 201410114164.7, filed on Mar. 25, 2014 and entitled “auxiliary device for mobile terminal and mobile terminal product”, which is incorporated herein by reference in its entirety. 
       TECHNICAL FIELD 
       [0002]    The present invention relates to the field of telecommunication technology, in particular to an auxiliary device for a mobile terminal, and a mobile terminal product. 
       BACKGROUND 
       [0003]    Along with the rapid development of IC technologies, the mobile communication industry is going to a real mobile information age. A mobile terminal, with strong processing capacity, is now changing from a simple communication tool to a comprehensive information processing platform, which results in a board space for the development of the mobile terminal. In order to view information on the mobile terminal in a clearer manner, the mobile terminal, such as a mobile phone, is required to have a larger volume and thereby a larger screen. As a result, it is harder to operate the mobile terminal to some extent. 
         [0004]    In the prior art, a Chinese patent application (CN01258909.8), entitled “additional rocker for mobile phone”, discloses a method for controlling keys via a rocker, in which the keyboard is sheathed with the rocker and controlled via the rocker in a mechanical transmission manner. 
         [0005]    This method is merely used to change “control by keyboard” into “control by rocker” through the mechanical transmission. However, it is hard to implement this method and operate the mobile phone, because a thickness of the mobile phone will increase due to the addition of the rocker. Moreover, a development trend of the current mobile phone is to gradually omit the keys, so it is impossible for the method using the rocker to effectively operate the mobile terminal without any keys. 
         [0006]    Hence, there is a need to provide an auxiliary device for the mobile terminal so as to overcome the above-mentioned drawbacks.
