FIELD OF THE INVENTION 
     The present invention is in the field of trampoline accessories. 
     DISCUSSION OF RELATED ART 
     With development in industry and commerce and improved lifestyle, people are paying more attention to exercise. People need varying levels of physical activities and a variety of different types of sports to match these different needs. The progress has led to developing varying sorts of both exercise types and fitness equipments. The backyard trampoline has become more popular recently for body conditioning. It is said that the trampoline can train one&#39;s jumping ability and also improve one&#39;s power, balance, and reaction. 
     A typical trampoline frame is round or rectangular. The trampoline support mostly relies on the bottom of the frame to support the frame above the ground. There is a first bed side which is formed as a net or mesh having an outside face that provides upward restoring force on the surface of the net. When force is applied downward, the surface of the net restores to a neutral position to rebound the mesh bed. Springs connecting the bed to the trampoline frame provide restoring force. Thus, users can bounce on the face of the net for a jumping movement exercise. 
     Besides providing a rebound surface, the traditional trampoline provides no other feature. Unfortunately, sometimes users become bored with the traditional trampoline leading to dangerous and unsafe activity. Sometimes users discontinue use of the trampoline. It is desired to have an improvement upon the traditional trampoline. 
     Over time, inventors have improved the traditional trampoline. In United States Patent Publication 2005/0227812, of Oct. 13, 2005 in inventor James describes a trampoline mat and method of making the trampoline. This is an improved trampoline mat is capable of being attached to a trampoline frame using a plurality of coil springs. A variety of structural improvements have been added to the traditional trampoline over time. 
     Inventor Samuel Chen improved the trampoline United States Patent Publication 2006/0135321 of Jun. 22, 2006 by providing a lighted trampoline, the disclosure of which is incorporated herein by reference. 
     SUMMARY OF THE INVENTION 
     A trampoline has a bed. The bed is made of a sheet of fabric having an exterior periphery. A frame includes legs supporting the frame from the ground. A plurality of springs attach the bed to the frame. A light sound module is suspended under the bed. The light sound module includes a light emitting element mounted on a rotation rod. The rotation rod is mounted on a rotation axis, and the rotation rod is driven to rotate by a motor. A plurality of elastic cords has a length, namely a first elastic cord, a second elastic cord, and a third elastic cord. 
     The first elastic cord has a first elastic cord inside end connected to the light sound module. The second elastic cord has a second elastic cord inside end connected to the light sound module. The third elastic cord has a third elastic cord inside end connected to the light sound module. The first elastic cord has a first elastic cord outside end connected to either the bed or frame. The first elastic cord has a first elastic cord outside end connected to either the bed or the exterior periphery. The second elastic cord has a second elastic cord outside end connected to either the bed or the exterior periphery. The third elastic cord has a third elastic cord outside end connected to either the bed or the exterior periphery. 
     A plurality of buckle hooks includes a first buckle hook attached to the first elastic cord outside end, a second buckle hook attached to the second elastic cord outside end, and a third buckle hook attached to the third elastic cord outside end. The trampoline may also have a fourth elastic cord having a fourth elastic cord inside end attached to the light sound module, and having a fourth elastic cord outside end connected to either the bed or the exterior periphery. 
     A first adjustment buckle is attached to the first elastic cord inside end, and the first adjustment buckle adjusts the length of the first elastic cord. A second adjustment buckle is attached to the second elastic cord inside end. The second adjustment buckle adjusts the length of the second elastic cord. The third adjustment buckle is attached to the third elastic cord inside end, and the third adjustment buckle adjusts the length of the third elastic cord. 
     The light emitting element of the light sound module includes a first LED element at a first radius and a second LED element at a second radius. As the first LED element spins and as the second LED element spins, the first LED element can draw a circle having a first radius and the second LED element can draw a circle having a second radius. The first radius is closer than the second radius to the rotation axis. The first radius can be called the inside radius and the second radius can be called the outside radius. Additional light emitting elements can be linearly disposed on the rotation arm. The rotation arm can be a flexible or rigid printed circuit. 
     The present invention of a flash spinner is a more sophisticated improvement on the prior art. This invention incorporates a lighted trampoline having a frame, a bounce member and a bounce sensor, sensing bounces to activate lights and provide sounds for entertaining and training purposes. The present invention uses the bouncing movement of the user to activate a sound and light module on a trampoline to provide safety and entertainment to trampoline users. 
     The present invention provides a trampoline with entertaining sound and light effects including: a frame, a net, an elastic component, a light device, and frame legs. The bottom of the frame has the legs that primarily supports the frame. The bed is mounted to the frame by a set number of springs, also known as elastic components such as helical springs. The bed is is bounded within the frame to form a margin and a bed surface edge. The light device is fixed underneath the bed to be contacted by a user when a user jumps on the bed. 
     The electrical circuit board at the bottom of the box set is connected to a transparent superstructure. An electric circuit board is connected to vibration sensors. A light and sound emitting unit is powered by a power supply unit that can be a battery box or household electric current. The box set has a peripheral edge with rope holes for receiving a number of elastic rope connections at one end. The elastic rope other end connects to frame. A fixed sound light device vibration trigger can be a spring and pole vibration switch mounted to achieve conduction actuation. The vibration switch is typically soldered to the circuit board to control the light emitting unit. The light-emitting unit of the central box set bottom has a combination of a rotating rod with light emitting elements such as LED&#39;s mounted in an array on the rotating rod. The rotating rod is set on the motor shaft. The LED&#39;s can be mounted at an angle other than a normal angle. The angular difference can provide a greater field of display. For example, the LEDs can be mounted at a 45° angle to the plane of the rotating rod. 
     The sound and light device circuit board connection is used to issue music, voice and sound on mounted speakers. To provide additional adjustability, one end of the elastic rope can be connected to an adjustment buckle with the other end of the connection being a button hook. 
     A sound element is mounted to an electronic circuit housed within the light sound module, and the electronic circuit is actuated by a vibration sensor preferably soldered on the electronic circuit board. The rotation rod can be a printed circuit formed as a strip. 
     An object of the invention is to allow the user to activate a sound and light device under the mesh bed while the user bounces on the trampoline. The device includes an automatic sensor in the form of the vibration switch that enhances trampoline fun and safety with flashing sound and spinning lights.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention provides the structure of the trampoline with sound and light effects for entertainment. The invention includes: a frame  1 , a net  2 , an elastic component  3 , and sound light device  4 , where the bottom of the frame features a majority of the supporting leg  11 . The mesh in the frame contains a set number of elastic components connected at set intervals between the frame  1 , margin, and net surface edge. The light device is set at the bottom of the bed  2  that be formed as a net or made of a mesh. The frame  1  has a bed supporting portion and supporting legs. The bed supporting portion has connections for receiving springs  3 . Springs are elastic elements that can be made of metal or fiberglass or even plastic elements. The elastic elements can also be called elastic components. 
     The sound light device is preferably made as a plastic box that can be round. The plastic box may have an upper transparent superstructure  412  which acts as a lens that fits over a capacity set box  41  that acts as a main housing for the sound light device. The electrical circuit board  42  at the bottom of the capacity set box  41  is connected to a transparent superstructure that can be snapped into place over the capacity set box  41 . The upper transparent superstructure  412  is preferably made of an impact resistant plastic that is soft enough not to crack when jumped upon. 
     Electric circuit boards  42  are connected to the vibration sensors  43  such that the vibration sensors are part of the electric circuit of the electric circuit boards. The electric circuit boards are preferably printed circuit boards with component soldered on the printed circuit boards. 
     A light-emitting unit  44  includes a power supply unit  45  to power the lights and speakers of the light emitting unit  44 . The electric circuit board  42  is connected to the driver of the speaker. The driver of the speaker can be a rectangular element mounted facing downward on an underside of the electric circuit board  42 . The electric circuit board  42  can be mounted on a pair of mounting posts with openings disposed on the printed circuit board for allowing a pair of screws to secure the openings to the mounting posts. The driver of the speaker is preferably soldered to the printed circuit board and facing downward. The driver of the speaker emanates sound initially downward which vibrates the capacity set box. The sound then transmits to the transparent superstructure such that the transparent superstructure and the capacity set box become a speaker for transmitting sound vibrations through the air to the user. The bottom surface of the capacity set box  41  can be open with a plurality of openings to allow sound to travel to the user. 
     The light-emitting unit  44  may include a set of assembled components including the motor  441 , formed as a bottom box mounted to a top surface of the capacity set box on a pair of mounting posts. Preferably, the shaft of the motor directly connects without gearing to a rotation rod  442 . The rotation rod  442  can be flexible and also can be a printed circuit. The rotation rod  442  can also be a printed circuit board in a rigid form. 
     The rotation rod  442  is formed as a rotating lever and preferably has a counterbalance which can also be lighted. A plurality of light-emitting elements  443  such as a light-emitting diode (LED) can be mounted to a top or bottom surface of the rotation rod  442 . When the light emitting unit  44  is activated, it plays sound to the speaker which can be a discrete element mounted to a bottom side of the circuit board  42  or the speaker can be the entire housing of the sound light device  4 . When the light emitting unit  44  is activated, the motor  441  spins and rotates the rotation rod  442 . The rotation rod  442  as a plurality of light emitting elements that can display a message, display a sequence, or display a light design. 
     The power supply unit  45  is a battery box. The battery box preferably has a screw for preventing young children from accessing and swallowing the batteries. The power switch  46  pierces the bottom of the box  411  and is accessible from the bottom of the box. The capacity set box  41  peripheral edge has rope holes  413  for a number of elastic rope  47  to connect at an inside end. The adjustment buckle  48  can be used for adjusting a length of elastic cord. The adjustment buckle  48  can be installed toward the inside end of the elastic cord. 
     The elastic rope  47  connects at an outside end to the frame. When the light sound device receives vibration, it activates. A buckle hook  49  facilitates triggering conduction of vibrations. The circuit board may have a processor to control the light emitting unit. The frame receives a buckle hook mounted on the elastic cord  47 . Alternatively, the buckle hook can be attached to the springs or the external periphery of the bed. 
     When assembled according to  FIG. 10 , the user will stand atop the bed  2  to jump. The mechanical operation is similar to traditional trampoline operation. When the user exerts force on the the bed, the bed  2  will subside in the direction of the force. This will produce a change in the springs  3 , so that original condition of the bed  2  will be restored by the springs  3 . The recovery of the bed rebounds the user upward. 
     Each time force is exerted on the bed  2 , the bed  2  will subside below the location of the sound light device  4  of the capacity set box  41 . As a result, the elastic rope  47  will pull and stretch, which will cause the elastic rope  47  to pull the capacity set box  41  back to its original condition. The impact of the bed on the sound light device sound light device  4  causes vibrations that trigger vibration sensors  43  to activate by closing circuit on the electric circuit board  42 . The electric circuit board controls the light-emitting unit  44  for moving the light-emitting unit and for activating other sound devices. 
     The light-emitting unit  44  of the motor  441  drives the rotation rod  442 . While the rotation rod  442  spins, the light-emitting element  443  flickers. This illumination can be intermittent or continuous, and dazzling lighting effects can form around the ring of the trampoline. In addition, the sound light device power switch  46  turns off the device. This allows for the lighting and sound effect to be terminated at the user&#39;s discretion. 
     The present invention preferably provides a trampoline having both sound and light entertainment simultaneously in addition to the bouncing movement. Moreover, in combination with the under bed  2  sound light device  4 , the light-emitting unit  44  preferably provides a spinning motion to the lights, and also affecting the sound to further enhance the fun factor of the trampoline. 
     The above is the preferred embodiment. It should be pointed out that a person of ordinary skill in the art can further make improvements and polish these improvements without departing from the original scope of the claims. Alterations to the specification can be made within the scope of the claims. For example, the brightness of the lights may be adjusted according to the trampoline bed fabric mesh so that the lights are visible to the user through the trampoline bed.
