Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2023/143663 filed on Dec. 29, 2023, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the field of waterproof earphones, and in particular to, a core assembly of a waterproof earphone and a waterproof earphone using the core assembly. BACKGROUND With the rapid development of consumer electronic products, electronic products such as smartphones and earphones have become a part of people's lives. Among them, an earphone, as a conversion unit, can receive an electrical signal from a media player or a receiver and convert the electrical signal into a sound wave that can be heard by a human ear, so that a user can clearly hear the sound wave in a noisy environment. The earphones are used in a wide range of scenarios. Among the many usage scenarios, there are some specific usage scenarios (e.g., scenarios of using earphones in outdoor rain or while swimming) in which the earphones are required to have good waterproof performance, especially for a core assembly of the earphones. Therefore, a core assembly with better waterproof performance and a waterproof earphone including the core assembly are needed.
