Physics of the Turntable :: physics sound music

Have you ever wondered how a record player works? Probably not. After all, who still listens to records? astonishingly enough, turntables be making a come back. With the recent surge of hobby in hip bound off music, popular attention has been turned towards the turntable, utilise by DJs to provide beats, loops and scratching for virtually all of todays hip hop groups.The inner workings of the turntable may seem complex at first but after reading this paper it should become piddle that, like all things, the record player works on introductory principals of physics. In fact, the turntable is remarkable in that the basic physical principles nooky it are quite simple. Some of these will be explored here. Please screw your visit.How a record player works is quite simple. A ride is somehow connected to a solid saucer so that the saucer is outflankd at a constant speed. On top of the rotating disc ( phonograph recording), The record is placed on top, with a slip mat in between. The slip mat can serve two functions. In the old to hold the record in place so that it would not rotate independently of the record. Now, however, the slip mat serves a more than different function. preferably of holding the record in place, the slip mat is now apply to reduce the friction between the spinning platter and the record. This way a DJ can scratch (manually move the record, usually at high-pitched speeds) the record while the platter continues to spin underneath. Once the record is rotating, a stylus glides along the grooves and picks up the vibrations, these are then converted into sounding sound.There are many an(prenominal) different models of turntables still macrocosm manufactured. Of those being sold, it is possible to divide them into two separate categories based upon their motor system. or so all record players being manufactured today have any belt drive or direct drive motors. For the reasons discussed below, direct drives are accepted as the indu stry standard for professional DJs and turntabilists.Belt contain-There are two advantages to the belt drive design. The motor in a belt driven turntable is set away from the platter by means of a continuous belt loop. This minimizes vibration to the platter and thus needle skipping. Also, belt drive models tend to be much cheaper than their direct drive counter parts.These advantages, however, do not balance the many short falls of the belt drive design.
