The earphone (100) comprises a shell
assembly (10) and an
air conduction loudspeaker (12), and the shell
assembly (10) is provided with accommodating cavities (1001 and 1002) and a sound outlet hole (1080) used for communicating the accommodating cavities (1001 and 1002) with the external environment; the
air conduction loudspeaker (12) comprises a
magnetic circuit assembly (120), a
voice coil (122) and a vibrating diaphragm (123), the
magnetic circuit assembly (120) comprises a cover body (121) with an opening end (1211) and an annular
flange (1212) which is arranged at the opening end (1211) of the cover body (121) and protrudes out of the outer circumferential surface of the cover body (121), the edge of the vibrating diaphragm (123) is fixed to the annular
flange (1212) and covers the opening end (1211) of the cover body (121), the
voice coil (122) is connected with the vibrating diaphragm (123), and the opening end (1211) of the cover body (121) protrudes out of the annular
flange (1212). The diaphragm (123) is located on a side of the cover body (121) facing away from the sound outlet hole (1080). Through the mode, the space
utilization rate of the shell assembly (10) can be effectively improved, the overall size of the whole shell assembly (10) can be reduced, and the
sound quality can be effectively improved through the mode.
