Abstract
A printed circuit board includes a pad to receive an electric signal from a controller, a plurality of signal lines connected to the pad to transmit the electric signal received at the pad, and a signal transmission unit connected to the signal lines to transmit the electric signal to a coil. The plurality of signal lines are configured to face each other in at least a partial region and/or disposed in a zigzag form in at least a partial region. If the printed circuit board and a vibration actuator including the printed circuit board are used, it is possible to change a high frequency interference region according to a pattern by changing a pattern of the printed circuit board, and to improve receiving efficiency of an antenna by reducing high frequency noise.
