METHOD FOR DRIVING A SPEAKER CAPABLE OF CONTROLLING THE ROTATIONAL DIRECTION, THE ROTATION QUANTITY, AND THE ROTATION PATTERN OF AN EXERCISING OBJECT WITH THE DRIVING SIGNAL TRANSFERRED TO A MOTOR

摘要

PURPOSE: A method for driving a speaker is provided to prevent the degradation of performance and eliminate noises by preventing the cracking of a vibration plate due to a physical impact through the removal of the vibration plate.;CONSTITUTION: An input unit receives the signal of a sound source(S210). A signal converting part receives the signal of the sound source(S220). The signal converting part distributes the signal of the sound source to a plurality of signals(S230). The number of the signal, which is divided through the signal converting part, depends on the structure of a driving part. A driving signal is formed by modulating a divided signal(S240). The driving signal is transferred to the driving part to perform a driving operation(S250). The driving part rotates a motor into a forward direction and a reverse direction through a plurality of driving signals.;COPYRIGHT KIPO 2012
