EARPHONE
Document Type and Number:
WIPO Patent Application WO/2024/067318
Kind Code:
A1
Abstract:
An earphone (100), comprising an earbud (10) and a measurement sensor (30), which is arranged inside the earbud (10), wherein the measurement sensor (30) is used for measuring blood oxygen saturation and a heart rate. The earbud (10) comprises a first contact portion (11) and a second contact portion (12), wherein when the earphone (100) is worn on the ear (300), the first contact portion (11) is in contact with the inner bottom face of the cavum conchae (301) of the ear (300), and the second contact portion (12) is in contact with the inner surface of the tragus (302) of the ear (300). A measurement sensor (30) is arranged on at least one of a first contact portion (11) and a second contact portion (12) of an earbud (10), which are in contact with the skin of the ear (300), such that the transmission distance between the measurement sensor (30) and the skin can be reduced, thereby effectively improving the precision of measurement performed by the measurement sensor (30) on health indexes such as blood oxygen saturation and a heart rate. Moreover, since the contact between the first contact portion (11) and the cavum conchae (301) and the contact between the second contact portion (12) and the tragus (302) are also relatively stable, the earphone (100) still has relatively good stability even in a moving scenario, such that the precision of measurement can be further improved.
