Abstract
(EN)
The present invention provides a vibration motor. The vibration motor comprises a housing having an inner cavity, magnetic oscillators separately accommodated in the inner cavity of the housing, and a magnetic component for driving the oscillator to vibrate. A first coil is fixed onto the housing. A second coil is fixed onto the magnetic component. An alternating current is applied to the first coil to drive the oscillator to vibrate along the direction of the inner cavity of the housing. An adjustable current is applied to the second coil to make the magnetic field of the magnetic component repel the magnetic field of the oscillator, and provide the restoring force at which the oscillator rebounds, so that the oscillator performs reciprocating motion in the inner cavity of the housing. The size of the restoring force generated by the magnetic component is changed by adjusting the size of the magnetic field generated by the magnetic component, thereby adjusting the resonant frequency when the oscillator vibrates. The vibration motor of the present invention can adjust the resonant frequency, so that the vibration motor can have a sufficiently high response within a wide range of frequency band.

La présente invention concerne un moteur à vibrations. Le moteur à vibrations comprend un boîtier ayant une cavité interne, des oscillateurs magnétiques logés séparément dans la cavité interne du boîtier et un composant magnétique pour amener l'oscillateur à vibrer. Une première bobine est fixée sur le boîtier. Une seconde bobine est fixée sur le composant magnétique. Un courant alternatif est appliqué à la première bobine pour amener l'oscillateur à vibrer le long de la direction de la cavité interne du boîtier. Un courant réglable est appliqué à la seconde bobine pour amener le champ magnétique du composant magnétique à repousser le champ magnétique de l'oscillateur, et fournir la force de rappel à laquelle l'oscillateur rebondit, de telle sorte que l'oscillateur effectue un mouvement de va-et-vient dans la cavité interne du boîtier. La taille de la force de rappel générée par le composant magnétique est modifiée par réglage de la taille du champ magnétique généré par le composant magnétique, ce qui permet d'ajuster la fréquence de résonance lorsque l'oscillateur vibre. Le moteur à vibrations de la présente invention peut ajuster la fréquence de résonance, de telle sorte que le moteur à vibrations peut avoir une réponse suffisamment élevée dans une large plage de bandes de fréquence.
