Title:
磁気ギャップ方式の垂直振動運動器
Document Type and Number:
Japanese Patent JP4683361
Kind Code:
B2
Abstract:
A vertical movement vibrator of a magnetic gap type is provided. The vibrator can provide a sufficient vertical movement force by a structure that a bobbin coil connected to a vibration plate is disposed in a magnetic gap of a magnetic circuit. The vibrator includes a magnetic circuit which forms an annular magnetic gap, and forms a DC magnetic field in the magnetic gap, a driving coil which is movably inserted into the magnetic gap, the driving coil being vibrated up and down when a driving signal is applied, a driving signal supply unit for supplying the driving signal, a vibration plate to the lower side of which the bobbin is attached to accomplish vibration up and down, a vertical movement guide unit for guiding the vibration plate to perform vertical movement, and a unit which limits a movement range of the vibration plate, and simultaneously absorbs an impact.
