Abstract
A linear coil for inhibiting acoustic noise is provided. A rubber spacer is disposed in addition to the conventional linear coil. By means of the spacer, the vibration, generated when the deflection current passes through the linear coil, is absorbed. As a result, acoustic noise, caused by the collision between the linear coil and the printed circuit board, can be inhibited.
