Abstract
(EN)
A vibration motor, including a shell defining a cavity therein, an axis disposed entirely within the cavity, a first magnet which is rotationally movable relative to the shell and which includes at least two sections having alternating poles, and a second magnet including at least two sections having alternating poles. A first extension tab is attached to the first magnet and extends out of the shell via a slot. An unbalanced rotor is disposed between the first and the second magnets and is rotatable relative to the axis. The first extension tab is movable within the slot, such that moving the tab causes movement of the first magnet and changes a rotational position of the first magnet relative to the second magnet, thereby to change the efficiency of operation of the motor.

L'invention concerne un moteur à vibrations comprenant une coque dont l'intérieur forme une cavité, un axe disposé entièrement à l'intérieur de la cavité, un premier aimant mobile en rotation par rapport à la coque comprenant au moins deux sections ayant des pôles alternés et un second aimant comprenant au moins deux sections ayant des pôles alternés. Une première languette d'extension est fixée au premier aimant et s'étend hors de la coque par l'intermédiaire d'une fente. Un rotor déséquilibré est disposé entre les premier et second aimants et peut tourner par rapport à l'axe. La première languette d'extension est mobile à l'intérieur de la fente, de telle sorte que le déplacement de la languette provoque le mouvement du premier aimant et modifie une position de rotation du premier aimant par rapport au second aimant, ce qui permet de modifier l'efficacité de fonctionnement du moteur.
