     The invention relates in general to an electronic device module, an electronic device thereof, a protection element thereof and a method of raising working frequency thereof, and more particularly to an electronic device module with sensor, an electronic device thereof, a protection element thereof and a method of raising working frequency thereof. 
     2. Description of the Related Art 
     Conventional electronic device, such as a tablet PC, cannot be equipped with a fan for dissipating the heat due to the limitation of the space. Therefore, as long as the CPU of the tablet PC raises a working frequency thereof for a while, the tablet PC will generate extra heat and make the user&#39;s palm feel hot, not only causing nuisance to the user but also making it difficult to increase the working frequency of the CPU for the tablet PC.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 1A , an explosion diagram of an electronic device module according to an embodiment of the invention is shown. The electronic device module  100  comprises an electronic device  110 , an adhesive layer  130  and a protection element  120 . 
     The electronic device  110  is such as a tablet PC, a mobile phone or a hand-held electronic device. The electronic device  110  comprises a main body  111 , a device detection element  112  and a CPU  113 , wherein the device detection element  112  and the CPU  113  are disposed within the main body  111 . In the present embodiment, the device detection element  112  is a magnetic field sensor which can be disposed within the main body  111  or on an outer surface of the main body  111 . 
     The protection element  120  comprises a protection cover  121  and a protection cover detection element  122 . The adhesive layer  130  is such as a non-setting adhesive disposed between the main body  111  and the protection cover  121  for stabilizing relative positions between the main body  111  and the protection cover  121 . In the present embodiment, the protection cover detection element  122  is a magnetic element such as a permanent magnet disposed within the protection cover  121  or on an outer surface of the protection cover  121 . The protection cover  121  and the main body  111  can be combined together to avoid the main body  111  being worn and torn or to absorb the impact received by the main body  111  when falling to the ground and avoid the main body  111  being severely damaged. 
     Referring to  FIG. 1B , an assembly diagram of the electronic device module of  FIG. 1A  is shown. The protection cover  121  is formed by such as a thermal insulating material. The thermal barrier provided by the protection cover  121  impedes the main body  111  conducting the heat to the user&#39;s palm so that the user&#39;s palm will not feel hot. For instance, in a method of raising a working frequency of an electronic device, when the protection cover  121  and the main body  111  are combined together, the device detection element  112  and the protection cover detection element  122  will approach each other and generate electromagnetic induction, so that the CPU  113  of the electronic device  110  raises a working frequency thereof according to the electromagnetic induction. By doing so, the CPU  113  will generate extra heat, but the user&#39;s palm does not feel hot due to the thermal barrier of the protection cover  121 . Here, “approach” refers to “get close but not directly contact” or “directly contact”. In another embodiment, when the device detection element  112  and the protection cover detection element  122  are separated from each other, the CPU  113  reduces a working frequency thereof according to a departing movement between the device detection element  112  and the protection cover detection element  122 . 
     The CPU  113  may raise a working frequency thereof according to an electromagnetic induction between the device detection element  112  and the protection cover detection element  122  as well as a mechanical detection exemplified below. 
     Referring to  FIG. 2 , an explosion diagram of an electronic device module according to another embodiment of the invention is shown. The electronic device module  200  comprises an electronic device  210 , an adhesive layer  130  and a protection element  220 . 
     The electronic device  210  is such as a tablet PC, a mobile phone or a hand-held electronic device. The electronic device  210  comprises a main body  111 , a device detection element  212  and a CPU  113 , wherein the device detection element  212  and the CPU  113  are disposed within the main body  111 . In the present embodiment, the device detection element  212  is such as a mechanical button disposed on an outer surface of the main body  111 . 
     The protection element  220  comprises a protection cover  121  and a protection cover detection element  222 , wherein the protection cover detection element  222  is such as a protruding portion which cooperates with the device detection element  212 . The protruding portion is protruded from an outer surface of the protection cover  121  for triggering the device detection element  212 . 
     The position of the device detection element  112  corresponds to that of the protection cover detection element  122 . Therefore, when the protection cover  121  and the main body  111  are combined together, the protection cover detection element  122  triggers the device detection element  112 , and the CPU  113  raises a working frequency thereof accordingly. Although the CPU  113  generates extra heat, the heat is blocked by the protection cover  121  and the user&#39;s palm will not feel hot. 
     Referring to  FIG. 3 , an explosion diagram of an electronic device module according to another embodiment of the invention is shown. The electronic device module  300  comprises an electronic device  110 , an adhesive layer  130  and a protection element  320 . The electronic device  110  comprises a main body  111 , a device detection element  112  and a CPU  113 , wherein the device detection element  112  and the CPU  113  are disposed within the main body  111 . The protection element  320  comprises a protection cover  121 , a protection cover detection element  122  and a thermal conductive element  323 , wherein the protection cover detection element  122  and the thermal conductive element  323  are disposed on the protection cover  121 . The thermal conductive element  323 , such as a heat pipe, is disposed within the protection cover  121  for quickly conducting the heat to the outside of the electronic device  110 . When the protection cover  121  and the main body  111  are combined together, the CPU  113  raises a working frequency thereof according to an approaching movement between the protection cover detection element  122  and the device detection element  112 . By doing so, the CPU  113  will generate extra heat. However, the thermal conductive element  323  is capable of conducting the heat to the outside of the electronic device  110 , and the palm will not feel too hot. 
     In an embodiment, the electronic device  110  of the electronic device module  300  can be replaced by the electronic device  210 . In another embodiment, the protection cover  121  of the electronic device module  300  can be formed by a thermal insulating material. Under such design, the electronic device module  300  can selectively omit the thermal conductive element  323 . 
     While the invention has been described by way of example and in terms of the preferred embodiment(s), it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
