In addition, when wind blows from behind the user's ear to the cheek side of the user, the auricle (antitragus) can also play a role of shielding, preventing wind from directly blowing into the first sound pickup hole 32 to increase wind noise of the earphone 100.

In some embodiments, at least a portion of the second surface 212 is a curved surface 212a, and the first pick-up hole 32 is disposed on the curved surface 212a. The second surface 212 may be entirely curved 212a or a portion of the area may be curved 212a. Through setting up first pickup hole 32 and locating on curved surface 212a, can utilize the basic attribute of air fluid, the air current is blown to the flow path of earphone 100 department in the outline department when earphone 100, when the air current is through smooth curved surface 212a, the air current can not stop on the curved surface basically, can continue the backward motion along curved surface 212a, can reduce the turbulent flow that causes the wind noise in the air current and the contact of first pickup hole 32, reduce the intensity that the air current got into first microphone 31, reach the effect that suppresses the wind noise, and the influence of other direction wind is less to the second surface, also can reduce the wind intensity of the wind that gets into first pickup hole.

In some embodiments, third surface 213 is planar. By providing the third surface 213 to be planar, the cooperation of the third surface 213 with the second surface 212 may effectively direct the flow path of the wind at the surface of the body portion 21 after the wind contacts the earphone 100, and the third surface 213 is planar, which may increase the rate at which the wind flows at the third surface 213. In addition, when wind blows from other angles, such as from the head of the user to the foot, the third surface 213 is provided to be a plane, so that the rebound refraction amount of the wind on the third surface 213 is improved, and only a small part of the wind can reach the third surface 213, so that the effect of reducing wind noise can be achieved.

It can be appreciated that the first surface 211, the second surface 212, the third surface 213 and the fourth surface are respectively connected to different sides of the first outer surface 21a, and in the embodiment of the present application, by providing the second surface 212 with at least a portion of a curved surface, the third surface 213 is a plane, and it can also be considered that the first outer surface 21a may be substantially track-shaped, the side wall 21b may be track-shaped, and the first surface 211 and the second surface 212 may be opposite annular portions, which is also beneficial for improving the smoothness and the aesthetic appearance of the earphone 100.

In some embodiments, the side wall 21b is further provided with a protrusion 214, the protrusion 214 protruding with respect to the outer surface of the first sound pickup hole 32, and the protrusion 214 being provided near the edge of the first sound pickup hole 32. The number of the protrusions 214 may be one, two or more, by providing the protrusions 214 protruding with respect to the outer surface of the first sound pickup hole 32, the protrusions 214 may play a role of shielding wind, blocking a part of wind from entering the first sound pickup hole 32, and the protrusions 214 may also play a role of dispersing air turbulence, so as to break up and reduce the intensity of air flow generating wind noise, and reduce the intensity of wind entering the first sound pickup hole 32, so as to reduce wind noise.

In some embodiments, the earphone 100 further comprises a second microphone (not shown in fig. 1 to 4), which may be located in the receiving cavity 101, and the first surface 211 may be provided with a second sound pick-up hole 35 for picking up sound of an external space of the earphone 100 through the second sound pick-up hole 35, both the second microphone and the second sound pick-up hole 35 being close to the first side 103 of the earphone 100 at the second side 104 of the earphone 100. That is, the first sound pickup hole 32 is disposed close to the first microphone with respect to the second microphone, and the second sound pickup hole 35 is disposed close to the second microphone with respect to the first microphone, so that the length of the track 33 between the first sound pickup hole 32 and the first microphone, and the length of the track 33 between the second sound pickup hole 35 and the second microphone are shortened, facilitating miniaturization of the earphone. At this time, when the wind blows from the back of the user to the cheek side of the user, the auricle and part of the body of the earphone 100 can effectively shield the wind blown from the back of the ear, that is, the second sound pickup hole 35 is located at the wind shielding position, and also can effectively reduce the contact between the turbulence of wind noise in the air flow and the second sound pickup hole 35, thereby reducing the intensity of the air flow entering the second microphone, reducing the influence of the air flow on the sound pickup of the second microphone, and achieving the effect of suppressing the wind noise.

In some embodiments, the headset 100 may further include a processor (not shown in fig. 1-4) that may electrically connect the first microphone 31 and the second microphone. Wherein the processor may be in electrical and communicative connection with the first microphone 31 and the second microphone. Illustratively, the processor may obtain a first sound signal collected by the first microphone 31 through the first sound pickup hole 32, where the first sound signal may include a first wind noise signal and a first sound pickup signal, such as a corresponding voice signal when a user speaks, etc., and obtain a second sound signal collected by the second microphone through the second sound pickup hole 35, where the second sound signal may include a second wind noise signal and a second sound pickup signal. The processor may analyze and determine a difference in magnitude between the first wind noise signal and the second wind noise signal, and selectively process the first sound signal picked up by the first microphone 31 or the second sound signal picked up by the second microphone according to the different magnitudes. For example, when the first noise signal of the first sound signal is smaller than the second noise signal of the second sound signal, the processor will stop processing the second sound signal picked up by the second microphone, and the processor will output the corresponding first signal after the first sound signal is processed by filtering, in other words, at this time, the first microphone 31 is a microphone working in the earphone 100, the first microphone 31 in the earphone 100 bears the pick-up function, and the second microphone is in the off state; if the second acoustic noise signal of the second acoustic signal is smaller than the first acoustic noise signal of the first acoustic signal, the processor stops processing the first acoustic signal picked up by the first microphone 31, and outputs a second signal corresponding to the second acoustic signal after filtering. In other words, the second microphone is a microphone operating in the earphone 100, the second microphone in the earphone 100 performs the sound pick-up function, and the first microphone 31 is in the off state.

Specifically, when the wind blows to the user from the head on, the first pickup hole 32 is located on the second surface 212, that is, the first pickup hole 32 is located at the back position where the turbulent flow of the air flow is severe, so that the first wind noise signal picked up by the first microphone 31 is smaller, the first microphone 31 is a working microphone, and the second microphone is turned off; when wind blows to the user from behind, the second pickup hole 35 is arranged on the first surface 211, that is, the second pickup hole 35 is arranged at the back position with severe air flow turbulence, so that the second wind noise signal picked up by the second microphone is smaller, the second microphone is an operating microphone, and the first microphone 31 is closed. In this embodiment, the earphone 100 provided by the embodiment of the present application can select the microphone that is less affected by the external airflow to work according to the environmental adaptability, which is beneficial to reducing the wind noise of the earphone 100 and improving the hearing experience of the user. In other embodiments, the earphone 100 may not include the second microphone, or the earphone 100 may not include the first microphone 31, which the present application is not limited to.

In some embodiments, the earphone 100 further includes a wind-proof component 36, where the wind-proof component 36 is fixed to the first sound-collecting hole 32 and covers the first sound-collecting hole 32, and a plurality of through holes 361 may be formed in the wind-proof component 36. The wind-proof component 36 can be made of plastic materials or steel materials, through the arrangement of the wind-proof component 36, flowing air turbulence which causes wind noise can be effectively prevented from entering the first sound pick-up hole 32, meanwhile, the through holes 361 can also have a dispersing effect on the air turbulence which passes through the wind-proof component 36, so that the air intensity which generates the wind noise can be dispersed and reduced, the impact of the air turbulence which causes the wind noise on the first microphone 31 can be weakened, the amplitude of the wind noise picked up by the first microphone 31 can be reduced, and the purpose of reducing the wind noise can be achieved. In other embodiments, the wind-proof assembly 36 may be fixed to the second sound-collecting hole 35 and cover the second sound-collecting hole 35, and the position, connection relationship between the wind-proof assembly 36 and the second sound-collecting hole 35 may refer to the position, connection relationship between the wind-proof assembly 36 and the first sound-collecting hole 32, which will not be repeated in the present application.

In some embodiments, the outer surface edge of the wind guard assembly 36 may be smoothly joined with the second surface 212, or the outer surface edge of the wind guard assembly 36 may be recessed relative to the second surface 212. Illustratively, when the edge of the outer surface of the wind-proof component 36 is recessed relative to the second surface 212, a recessed section is formed between the edge of the outer surface of the wind-proof component 36 and the second surface 212, which can protect the structural member at the recess, so that the first sound pick-up hole 32 at the recess is less affected by the air flow outside the recess, and thus the wind noise caused by the air flow is less generated by the sound input from the first sound pick-up hole 32, i.e. the wind noise interference during the weakening of the sound pick-up is relatively reduced, thereby improving the sound pick-up quality of the first microphone 31 and the use experience of the user.

In some embodiments, the earphone 100 further includes a waterproof and breathable member (not shown in fig. 1-4) and a dust-proof member (not shown in fig. 1-4), wherein the wind-proof assembly 36, the dust-proof member and the waterproof and breathable member are stacked, are fixed to the first sound pickup hole 32, and cover the first sound pickup hole 32.
