Title: Electronic apparatus for preventing speakers from making unwanted noise

Description:
BACKGROUND 
     1. Technical Field 
     The disclosure relates to electronic apparatuses and, more particularly, to an electronic apparatus for preventing speakers from making unwanted noise. 
     2. Description of Related Art 
     Electronic apparatuses, such as tablet computers, mobile phones, have become thinner and thinner. It is easy to get unwanted noise from a speaker when the speaker of the electronic apparatus is playing sound due to space restriction. For example, when the speaker plays sounds in a predetermined frequency, the speaker and the cover of the electronic apparatus may easily resonate, which results in the speaker making unwanted resonating noise. 
     Therefore, what is needed is an electronic apparatus for preventing speakers from making unwanted noise to overcome the described shortcoming.

     DETAILED DESCRIPTION 
       FIGS. 1-3 , show an electronic apparatus employing a speaker for playing sounds. For illustration purposes, a tablet computer  1  is used as an example. The tablet computer  1  includes a front cover  10 , a back cover  20 , and a screen  30 . The screen  30  is accommodated between the front cover  10  and the back cover  20 . 
       FIGS. 4-5 , show a joint element  40  fixed on the back cover  20  and abutting a rear side of the screen  30 . The joint element  40  is made of elastic material. Therefore, the back cover  20  is in contact with the screen  30  via the joint element  40  constantly. 
     The joint element  40  is a cantilever and can be designed with a number of shapes, such as, substantially, L-shaped, T-shaped, upside-down L-shaped, or upside-down T-shaped. In the embodiment, the joint element  40  is a shape of “L” and comprises a body  41 , a connection portion  42 , and a protrusion portion  43 . The body  41  is a rectangular, the connection portion  42  vertically extends from the body  41  and is fixed on the back cover  20 , and the protrusion portion  43  is positioned on the external surface of the body  41 . 
     A speaker  50  is positioned on the front cover  10 . The back cover  20  is connected with the screen  30  via the joint element  40 . The protrusion portion  43  of the joint element  40  is on the top of the screen  30 , and therefore, four elements which include the speaker  50 , the front cover  10 , the back cover  20 , and the screen  30  are directly or indirectly connected with each other, thereby avoiding resonating points when the speaker  50  plays sounds and prevents the speaker  50  from making unwanted noise. 
     Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
