     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to FIGS. 1,  2  and  3 , the present invention provides a pen with multiple lighting colors variably accompanying sound actuation basically comprising at least a pen body  10 , a tubular cylindrical holder  20  and a pen head  30 . 
     The pen body  10  is adapted to receive a writing cartridge  11  therein and is made of a transparent material such as transparent plastic in order to guide the light source, generated by a music-light generating means  50  of the invention, and to diffuse the light source emitted outwards. 
     The tubular cylindrical holder  20 , connected to the top of said pen body  10 , is provided with a hollow chamber  22  formed like a sound box for resonance so that several sound holes  21  are opened and properly positioned on its surface for generating sweet sounds resonating inside said chamber. Also, the tubular cylindrical holder  20  of the invention is especially made of metal material making its surrounding walls capable of electrical conduction. 
     With reference to FIGS. 2,  3  and  4 , a music-light generating means  50 , capable of generating sound and light simultaneously, includes a multicolor LED base  51 , an integrate circuit  52  directly installed on the bottom of said multicolor LED  51 , an electro-magnetic transducer  55  with a pair of connecting feet  56  connected to said beak) multicolor LED base  51  and said integrate circuit  52 , and a pair of bending positive electrode  53  and inclined negative electrode  54 . The outer dimension of said music-light generating means  50  is properly smaller than the interior dimension of the tubular cylindrical holder  20  in such a manner as to define said music-light generating means  50  positioned therein. 
     With reference to FIGS. 4 and 5, said multicolor LED base  51  contains a plurality of LED chips capable of generating different color of light source. The practical embodiment of the invention is to provide multiple LED chips, including at least red LED chip, green LED chip and blue LED chip connected to L 1 , L 2  and L 3  of said integrate circuit  52  shown in FIG. 5 to generate multiple colors corresponding to the musical scale of music. The multiple colors lighting may be emitted by multiple chips on board, Surface Mounted Devices or multiple through-hole lamps. Under the control of predetermined programs of said integrate circuit  52  and according the cadence or rhythm of song or music, each single LED chip may be alternately selected in such a way to emit its own mono-color light, or two or more single LED chip may be alternately selected in such a way to simultaneously emit and mix their own mono-color lights as other different color lights. Therefore, said multicolor LED base  51  of the invention is capable of generating at least seven color light sources which variably accompanies the rise and fall of sound or music played by the programs of said integrate circuit  52 . 
     The electro-magnetic transducer  55  of the invention, is not like a buzzer or a sound generating device commonly used in several prior art. The prior art invention are designed without sound resonating media; therefore, sounds generated are almost hardly heard because they are not generated through resonance sound media. In contrast, the tubular cylindrical holder  20  of the invention is invented as a sound resonance box which is used as a sound resonance medium for said electro-magnetic transducer  55  to generate sound by resonance effect. Using the tubular cylindrical holder  20  as a resonance box constitutes a drastic and very important improvement over the prior art. Using the resonance medium of this invention sound is generated from said electro-magnetic transducer  55  and transmitted through said sound hole  21  of said tubular cylindrical holder  20  thereby producing outward sweeter sound than that of the prior art. 
     The electro-magnetic transducer (referred as E.M.T.)  55  of the invention provides a pair of connecting feet  56  connected to said multicolor LED base  51  as shown in FIG. 4, and said pair of connecting feet  56  is respectively connected to the M 01  (Music Output  1 ) and M 02  (Music Output  2 ) of said integrate circuit  52  as shown in FIG.  5 . Accordingly, under the control of said integrate circuit  52  of the invention, said music-light generating means  50  may be reduced to practice and simultaneously generate pleasant sound or music for hearing and for synchronously accompanying the variety of cadence or rhythm of sound or music played to emit at least seven different color light sources for sight purposes, when power is supplied through said bending positive electrode  53  and said inclined negative electrode  54  to said music-light generating means  50 . 
     The bending positive electrode  53 , with both ends bent, is connected to VCC of said integrate circuit  52  by its one end as shown in FIG. 5, and its other end is positioned on the position above the top of said electro-magnetic transducer  55 . In order to prevent short circuiting, the shape of said bending positive electrode  53  is desired to be kept at a distance from both said tubular cylindrical holder  20  and said electro-magnetic transducer  55  as shown in FIG.  3 . The inclined negative electrode  54  is folded into an inclined shape, wherein one electrode is connected to GND of said integrate circuit  52  as shown in FIG. 5, and the inclined end is positioned on the position against the surrounding walls of said tubular cylindrical holder  20  for conductance when said music-light generating means  50  is securely positioned inside the chamber of said tubular cylindrical holder  20  as shown in FIG.  3 . 
     Referring to FIGS. 2 and 3, a set of batteries  40 , used as a power source of said music-light generating means  50  are connected to said bending positive electrode  53  with their positive electrode. When both said music-light generating means  50  and said batteries  40  are fitted into the chamber  22  of said tubular cylindrical holder  20 , a pen head  30 , made of metal material, is used to fasten on the top end of said tubular cylindrical holder  20  to completely form said chamber of said tubular cylindrical holder  20  as a sound box, and simultaneously to secure said music-light generating means  50  and said batteries  40  in their proper positions by way of a insulator  32  installed on front end of said pen head  30  securely against the top of said batteries  40 . The pen head  30  is also provided with a push-button switch  31  whose bottom has a connecting spring  33  to serve as a contact with said batteries  40 . 
     When push-button switch  31  is pushed down the connecting spring  33  is moved down and is totally against the top of the batteries  40 . A close circuit conductance path is constituted by said connecting spring  33 , said pen head  30  made of metal, said tubular cylindrical holder  20  made of metal, said music-light generating means  50  (through said inclined negative electrode  54 , said integrate circuit  52 , said bending positive electrode  53 ), and said batteries  40 . Thus, once supplied power from said batteries  40  is provided said music-light generating means  50  immediately activates said multicolor LED base  51  capable of generating up to seven color light sources variably accompanying the cadence or rhythm of sound or music played according to predetermined programs of the integrate circuit  52 . 
     When the push-button switch  31  is pushed again, said connecting spring  33  of said push-button switch  31  is released and a gap is maintained from the top of said batteries  40 . The power from said batteries supplied to said music-light generating means  50  is stopped so that those different color light sources variably accompanying the cadence or rhythm of sound or music played are deactivated. 
     While particular embodiments of this invention have been shown in the drawings and described above, it will be apparent, that many changes may be made in the form, arrangement and positioning of the various elements of the combination. In consideration thereof it should be understood that preferred embodiments of this invention disclosed herein are intended to be illustrative only and not intended to limit the scope of the invention.
