Abstract

La présente invention concerne un module de haut-parleur et un dispositif intelligent monté sur la tête. Le module de haut-parleur comprend un boîtier de module et une unité de haut-parleur. Le boîtier de module est pourvu d'une cavité de réception à l'intérieur de celui-ci. Le haut-parleur est placé dans la cavité de logement et divise la cavité de logement en une cavité sonore avant et une cavité sonore arrière. Un trou de sortie du son, qui est en communication avec la cavité sonore avant, et un trou de fuite du son, qui est en communication avec la cavité sonore arrière, sont prévus dans le boîtier du module. Une surface extérieure du boîtier du module comprend une première surface plane, une deuxième surface plane et une surface en forme d'arc, la première surface plane et la deuxième surface plane étant opposées l'une à l'autre ; la surface en forme d'arc est en liaison lisse avec la première surface plane ; le trou de sortie du son est prévu dans la surface en forme d'arc et la première surface plane ; et le trou de fuite du son est prévu dans la deuxième surface plane. Par rapport à l'art apparenté, le module de haut-parleur fourni dans les modes de réalisation de la présente invention peut avoir la fonction d'atténuer le son d'un champ sonore externe, de sorte que le problème de fuite sonore du champ sonore externe est résolu, ce qui est bénéfique pour protéger la vie privée d'un utilisateur, ce qui permet d'avoir une expérience d'utilisation relativement bonne.
