The invention discloses a
headset capable of improving the low-
frequency sound insulation performance. The
headset comprises an earmuff shell forming an earmuff cavity, a
loudspeaker located in the earmuff cavity and a
guide tube with two ends open; and one end of the
guide tube stretches into the
loudspeaker and is located under a diaphragm of the
loudspeaker, and the other end of the guide tubepenetrates through the earmuff shell to be communicated with the outside. According to the
headset, by adopting the mode of installing the
guide tube on the earmuff shell and stretching the guide tubeinto the position under the diaphragm of the loudspeaker, the corner frequency of a
low pass filter formed by an earmuff is reduced, and then the condition that outside
noise in more frequency bandspenetrates through the earmuff shell to enter the earmuff cavity can be prevented to improve the low-
frequency noise insulation performance of the headset product; and meanwhile, by stretching the guide tube out to the outer side of the earmuff shell, sound holes do not need to be formed in the earmuff shell, not only can the audio output requirement of the loudspeaker be met, but also the condition that the outside
noise passes through the sound holes to enter a back cavity of the loudspeaker can be prevented, therefore, the sound insulation and
noise reduction capacity of the headset is further improved, and the audio rendering quality of the headset is improved.
