X-rays are commonly produced by accelerating (or decelerating) charged particles; examples include a beam of electrons striking a metal plate in an X-ray tube and a circulating beam of electrons in a synchrotron particle accelerator or storage ring.
Examine your computer for jacks and ports that support your audio device. The location of certain jacks and ports will vary depending on your computer's make and model. For example, most jacks on a desktop computer will be located in the back; whereas jacks on a laptop computer are usually located on its sides.
First, check that your speaker cable is properly connected to the sound card on the back of the computer. As seen in the picture to the right, the sound card has multiple jacks. Speakers must be plugged into the Line Out connector, which usually indicated by an image of sound waves with an arrow pointing out. The jack itself is usually green in color. If your speakers connect through USB, plug them into any of the USB ports.
