Abstract

L'invention concerne une structure de réception vocale pour une machine à laver à tambour, comprenant une entrée vocale formée entre un élément de porte de machine à laver et une plaque avant de boîte, et une paroi de guidage s'étendant le long de la plaque avant de boîte. Une barre de décoration est située au niveau de l'entrée vocale, et un trou borgne est ménagé dans la barre de décoration. Un module vocal et un composant de microphone sont situés dans l'élément de porte de machine à laver qui comprend un cadre externe et un cadre interne ; un trou traversant de microphone, conçu de façon à correspondre au composant de microphone, est situé sur le cadre interne et est orienté vers la paroi de guidage. Une barre d'étanchéité est disposée entre la paroi de guidage et le cadre interne ; la paroi de guidage, la barre d'étanchéité et le cadre interne se rejoignent pour former une cavité de capture de voix. La présente invention peut réduire l'influence de la reconnaissance vocale provoquée par des facteurs tels que le bruit, la réverbération, l'interférence vocale humaine et l'écho. Le trou borgne ménagé dans la barre de décoration au niveau de l'entrée vocale peut guider l'utilisateur à émettre un signal vocal vers la cavité de capture vocale, ce qui permet d'empêcher le module vocal de venir en contact avec l'eau de lavage tout en garantissant l'effet d'utilisation du module vocal, et d'améliorer la stabilité de fonctionnement du module vocal.
