Abstract

La présente invention concerne un dispositif, un procédé et un appareil de déverminage d'écouteur, et un support de stockage lisible par ordinateur. Le dispositif de déverminage d'écouteur comprend une bobine conductrice fermée et un compartiment d'écouteur. Le compartiment d'écouteur est utilisé pour placer des écouteurs, la bobine conductrice fermée est utilisée pour générer un champ magnétique alternatif lorsqu'elle est excitée, et le champ magnétique alternatif est utilisé pour faire vibrer les diaphragmes des écouteurs placés dans le compartiment d'écouteur. Selon la présente invention, un déverminage d'écouteur automatique est obtenu.
