  • the ESA is activated because it is larger than the first reference volume and less than the second reference volume, the sound that is continuously detected repeatedly is not filtered and provided to the user, but only the sound of another size suddenly detected, such as a car horn, is provided according to the acoustic data. External beeps can be heard while maintaining the sound quality.
  • the external sound having a smaller size than the sound for warning the user may not be provided to the user by filtering, but may provide only a predetermined sound or more.
  • this method is to set the magnitude of the first reference volume higher, or to activate the ESA function, but to set the third reference volume between the first reference volume and the second reference volume to filter external sounds below the third reference volume. Can be implemented.

  • ESA function has the advantage that usability is improved by ON / OFF automatically according to the usage environment rather than manual ON / OFF by user.
  • the user may not provide noise due to friction between the main body and the user's body, so that the sound quality of the portable acoustic apparatus 200 is not degraded.

Abstract

L'invention concerne un dispositif audio portable comprenant : un corps principal ; un écouteur-bouton connecté au corps principal et monté sur l'oreille d'un utilisateur ; un microphone permettant de collecter des sons externes ; une unité de détection permettant de collecter les informations d'état du dispositif audio portable ; et une unité de commande permettant d'amener l'écouteur-bouton à fournir des sons en fonction des données sonores. Lorsque les informations d'état collectées par l'unité de détection satisfont à une référence prédéterminée, l'unité de commande active une fonction de perception sonore externe (ESA) qui est une fonction permettant de fournir les sons externes collectés par le microphone par le biais de l'écouteur-bouton. Le dispositif audio portable permet d'éviter qu'un utilisateur n'entendant pas les sons externes n'ait un accident même lorsqu'il utilise le dispositif audio portable.
