  • Ventilation apparatus
    Patent number: 7485991
    Abstract: A ventilation apparatus includes a stator, a vibrator arranged close to the stator, a permanent magnet to generate a magnet flux to form a path of the magnet flux along the stator and the vibrator, a coil wound around the stator or vibrator, and a ventilator coupled to the vibrator and operated by a linear reciprocating motion of the vibrator generated when an electric current is applied to the coil to change the magnet flux of the permanent magnet. Thus, the ventilation apparatus having a simplified ventilation structure increases a ventilation efficiency.
    Type: Grant
