Bluetooth earphone capable of being conveniently matched with ear cap

Abstract

A Bluetooth earphone capable of being conveniently matched with an ear cap comprises an earphone body and the ear cap, a sound outlet is formed in the earphone body, a part of a shell in the circumferential direction of the sound outlet axially extends to form a cylindrical jack, the ear cap comprises a sound transmission cylinder which is integrally connected, a sound transmission channel is formed in the sound transmission cylinder, and the sound transmission channel is communicated with the sound outlet. The peripheral contour of the sound transmission cylinder is matched with the contour of a hole cavity of the cylindrical jack, the outer diameter of the sound transmission cylinder is not larger than the inner diameter of the cylindrical jack, close-fitting protrusions are arranged on the outer wall of the sound transmission cylinder, the ear caps are inserted into the cylindrical jack through the sound transmission cylinder to be detachably connected with the earphone body, and the close-fitting protrusions are in interference connection with the inner wall of the cylindrical jack. According to the utility model, the portable disassembly and assembly of the ear cap and the earphone body are realized through the plug-in fit of the sound transmission cylinder and the cylindrical jack, and meanwhile, the annular close-fitting projection is designed for close-fitting and sealing the connection between the ear cap and the earphone body, so that not only is the in-ear state of the earphone switched conveniently, but also the use quality of the earphone in different in-ear states is ensured.
