Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of an International Application No. PCT/CN2024/130590, filed on November 7, 2024, the contents of which are hereby incorporated by reference. TECHNICAL FIELD The present disclosure generally relates to a field of electronic devices, and in particular to an earphone. BACKGROUND With a continuous popularization of electronic devices, the electronic devices have become indispensable social and entertainment tools in people’s daily lives. People have increasingly higher requirements for the electronic devices. The electronic devices such as earphones and smart glasses have been widely used in people’s daily lives. These electronic devices may be used in conjunction with terminal devices such as mobile phones and computers to provide users with an auditory feast. With the increasingly complex application scenarios of earphones, modern earphones are typically equipped with a microphone to collect user’s voice. However, it is difficult for the microphone to be fixedly assembled in an earphone housing. A sealing performance of the microphone is relatively poor, which also increases a difficulty of earphone manufacturing.
