Headset

The utility model discloses a headset which comprises a loudspeaker monomer, an audio signal line which is electrically connected with the loudspeaker monomer, a casing which accommodates the loudspeaker monomer, and a front cover which is laid on the casing. A front cavity is formed by a space between the front cover and the loudspeaker monomer. A rear cavity is formed by a space between the casing and the loudspeaker monomer. The rear cavity is divided into a main rear cavity and a bass rear cavity by a partition wall. An acoustic duct is laid in the cavity body of the bass rear cavity. The acoustic duct is curvedly bent and is filled in the cavity body of the bass rear cavity. One end of the acoustic duct is connected with the main rear cavity through a through hole of the partition wall, and the other end is communicated with the outside through a sound effusion hole in the casing of the bass rear cavity. According to the headset structure provided by the technical scheme, the low frequency performance and the medium frequency performance of the headset are effectively improved; the headset stability is ensured; and the headset has the advantage of beautiful appearance.
