     DETAILED DESCRIPTION OF THE INVENTION 
       [0019]    Now, preferred embodiments in accordance with will be described in detail with reference to the annexed drawings. 
         [0020]      FIG. 1  is a perspective view of the tent with a flood alarm in accordance with the present invention.  FIG. 2  is an instigating view of setting the tent with a flood alarm at the valley.  FIG. 3  is a cross-sectional view of a fixing bracket in accordance with the present 
         [0021]    As figured in  FIG. 1  to  FIG. 3 , the present invention is composed of a speaker( 110 ) which is assembled to the frame with fixing bracket( 500 ), a power supply( 210 ) which is connected with the speaker( 110 ) with wires( 120 ) and providing electricity, a sensor( 200 ) which includes the power supply( 210 ) and has sensing paper( 210 ) that absorbs water, and a fixing ball( 300 ) which is attached to an aspect of the sensor( 200 ) 
         [0022]    Now, each parts will be explained in detail. 
         [0023]    The speaker( 110 ) in located in the tent warns crisis situations to users who sleep in the tent. 
         [0024]    The speaker( 110 ) is assembled to the frame( 50 ) with the fixing bracket( 500 ). 
         [0025]    Desirably, the fixing bracket( 500 ) consists of an elastic material, and the assembling ball( 510 ) whose radius is same with that of the circular frame is penetrated and forming the incision part( 520 ) whose radius in smaller than that of the frame and trough the incision part, it is inserted to the frame by pressure. 
         [0026]    In other word, the fixing bracket( 500 ) which is assembled with the back of the speaker( 110 ) is located to meet the frame( 50 ) with the incision part( 520 ) and inserted by pressure, which makes the fixing ball insert to the frame( 50 ). 
         [0027]    The sensor( 200 ) consists of the case( 260 ) and the power supply( 260 ) which generates power by chemical batteries using the standard reduction potential in side of the case( 260 ) and the sensing paper( 240 ). 
         [0028]    The case( 260 ) is an rectangular exterior that covers the power supply( 210 ) and the sensing paper( 240 ). And its preferred that for simple structure and low price, the case( 260 ) should consist of a transparent coating paper. 
         [0029]    At first, looking into the chemical battery, an oxidation/reduction reaction occurs as a movement of electrons and electrical energy is generated by the movement of electrons. Since an availability to lose electrons is different for each metal, an electromotive force of a Nickel-Cadmium battery is 1.1V, Alkali battery is 1.5V by comparison Lithium ion battery is 3.6V. For reference, a Lithium ion battery uses carbon for cathode, transition metal oxide for anode and the electric energy is generated by moving ions of transition metal oxide to lattice structure of carbon atoms. A Nickel-Cadmium battery uses Nickel oxide for anode, Cadmium for cathode. However, because of the difference of oxidizing power between two substances is so small, the voltage is measured as 1.1V. 
         [0030]    Therefore, every battery consists of anode and cathode and when oxidation occurs in cathode, reduction occurs in anode and the chemical energy is converted to electric energy by moving electrons from cathode to anode. In other word, an electromotive force of a battery can be measured only if anode and cathode exists as a pair. Therefore, to figure an intensity of oxidation or reduction of metal concretely, there has to be an standard which makes us notice the reactions when oxidation or reduction happens. 
         [0031]    To solve above mentioned problem, Hydrogen is the atom which is needed because the standard for ionization tendency of metal is Hydrogen. Generally, the electrode that is manufactured by relieving Hydrogen gas of 1 atm to a Platinum electrode which is inserted in the 1M of Hydrogen solution at 25° C., 1 atm is called the standard Hydrogen electrode and the electromotive force of the electrode is E 0 =0.00V. A standard reduction potential is the voltage of the battery which is made of a standard Hydrogen electrode. In addition, 25° C., 1 atmosphere pressure, (metal) ion 1M are standards and metal is not a only material for standard reduction electrodes. 
         [0032]    The power supply( 210 ) is equipped in the case( 260 ), over the metal( 22 ) of the (+) pole the sensing paper( 240 ) is formed which absorbs water and upper surface of the sensing paper( 240 ) the metal( 230 ) of the (−) pole is formed. At this point, the sensing paper is extended from inside of the case( 260 ) toward lower direction. 
         [0033]    The wire( 120 ) connects metal( 230 ) of the (−) pole and the metal( 22 ) of the (+) pole to speaker( 110 ) as a series connection. 
         [0034]    It is preferred that multiple series circuits of the metal of the (−) pole and the sensing paper and the metal( 22 ) of the (+) pole to generate large voltage. 
         [0035]    This is one example of consisting a power supply of sensor in accordance with the present invention. 
         [0036]    First, prepare the lower case( 260 )(coating paper) of 8˜10 cm *5˜7 cm. 
         [0037]    Second, locate the copper plate which is the metal( 22 ) of (+) side by side on the lower coating paper. 
         [0038]    Third, attach the sensing paper( 240 ) which absorbs water to the copper plate. 
         [0039]    Fourth, put a copper chloride, an electrolyte, to the sensing paper( 240 ) 
         [0040]    Fifth, locate a magnesium which is the metal( 230 ) of the (−) pole on the sensing paper( 240 ) 
         [0041]    Sixth, After connect power supply( 210 ) which consists of two part as series connection with the enamel wire( 28 ), coat the power supply( 210 ) with the upper coating paper. 
         [0042]    At this point, the sensing paper is better to use a traditional Korean paper or rice paper to absorb water more efficiently. 
         [0043]    The fixing ball( 300 ) is formed at an aspect of the sensor and fixes the sensor( 200 ) tightly to valleys. 
         [0044]    The fixing ball( 300 ) is composed of the piece shaped spur( 340 ) at one side and the rubber band( 320 ) on another side, and the spur is inserted to crack of rocks or trees at valleys tightly first, fastens at trees in the vicinity secondly.  FIG. 4  illustrates one exemplary application of the floor alarm unit of the present invention. 
         [0045]    The fixing ball( 30 ) is manufacture to enable portability and easy set, and the spur( 340 ) can be used glue, not only piece shape. 
         [0046]    As above, the basic technological idea of the present invention is manufacturing a tent with a speaker that enables flood alarm. However, because this is just an example, and a person who has common knowledge of this field can apply various versions and examples, the true technological protection scope must be decided according to the scope of an request for a patent attached.
