Title:
SMART HEAD-MOUNTED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/027230
Kind Code:
A1
Abstract:
A smart head-mounted device comprising at least one lens (102) and at least one leg portion. The leg portion comprises a fixed section (104) and an engagement section (105). One end of the fixed section (104) is connected to the lens (102), and the other end of the fixed section (104) extends so as to form the engagement section (105). The engagement section (105) has an arc. The engagement section (105) is configured such that the engagement section (105) engages with the ear of a user. A sound emitting apparatus is provided in the fixed section (104) and a sound output hole (109) is provided on the fixed section (104). At least a part of the structure of the sound output hole (109) faces a region surrounded by the engagement section (105). The sound output hole (109) is configured to guide sound of the sound emitting apparatus to the exterior. The position of the sound output hole (109) is configured such that when the user wears the smart head-mounted device, the sound output hole (109) does not directly contact the head of the user, and is spaced from the earhole of the user by a predetermined distance. The predetermined distance is greater than or equal to 0.5 cm. The invention achieves open coupling between the sound emitting apparatus and the earhole.
