It should be noted that the earphone may be an in-ear wired earphone or a wireless earphone, and the earphone body 10 may be in communication connection with a mobile phone, a notebook computer, a desktop computer, an MP3, a wearable audio device, and other playing devices. The sound outlet pipe 11 is used for being inserted into an ear canal of a user, when the sound outlet pipe 11 is inserted into the ear canal, the sound outlet hole 112 is located in the ear canal, and sound played by the playing device can be transmitted to the ear canal through the sound channel 111 and the sound outlet hole 112 in sequence. The specific working principle of the earphone has been disclosed in the related art for a long time, and the present application is not exhaustive. The earcap 20 can prevent the ear canal from being damaged due to direct contact with the sound outlet tube 11, and meanwhile, the earcap 20 can bring good wearing comfort to people. The sound outlet passage 212 of the main body 21 is used to communicate with the sound outlet hole 112 of the earphone body 10, when the sound outlet tube 11 is inserted into the ear canal, the outer side of the main body 21 contacts with the ear canal to form a closed cavity, and the sound coming out from the sound outlet hole 112 can be transmitted to the ear canal through the sound outlet passage 212.

More specifically, the earcap 20 further includes a noise reduction portion 22, at least a portion of the noise reduction portion 22 is located in the accommodating cavity 211, an outer diameter of the noise reduction portion 22 decreases along the sound emitting direction, and a noise reduction cavity 30 is configured between an outer side wall of the noise reduction portion 22 and an inner side wall of the main body 21.

It should be noted that, in this application, the earcap 20 adopts the double-seal structure of the main body 21 combined with the noise reduction part 22, the thickness of the earcap 20 can be greatly increased, and the noise reduction cavity 30 can further increase the thickness of the earcap 20, the external noise needs to pass through the noise reduction part 22, the noise reduction cavity 30 and the main body 21 can enter the human ear, and meanwhile, when the noise enters the relatively airtight noise reduction cavity 30, the noise can be gradually absorbed, distorted and attenuated by the damping of the noise reduction cavity 30, so that the earcap 20 has good noise reduction performance, and the external noise can be effectively prevented from penetrating through the earcap 20 to enter the ear canal.

With continued reference to fig. 1 and 2, the main body 21 includes a contact portion 213 and a sound emitting portion 214; the contact portion 213 has a housing cavity 211; the sound emitting portion 214 is connected to the contact portion 213, and the sound emitting portion 214 has a sound emitting passage 212.

One end of the noise reduction part 22 close to the sound outlet channel is connected with the sound outlet part 214, and the noise reduction cavity 30 is formed by the noise reduction part 22, the contact part 213 and the sound outlet part 214 which are enclosed together, so that no air leakage gap exists between the noise reduction part 22 and the sound outlet part 214, and the sealing performance of the noise reduction cavity 30 can be improved.

With continued reference to fig. 1 and 2, in some embodiments of the present application, the noise reducer 22 includes a first noise reduction segment 221 and a second noise reduction segment 222; the first noise reduction section 221 is connected to the sound emitting portion 214, the second noise reduction section 222 is located on a side of the first noise reduction section 221 away from the sound emitting portion 214 and connected to the first noise reduction section 221, and the second noise reduction section 222 and the first noise reduction section 221 are arranged at an included angle. It should be noted that, the outer diameter of the noise reduction portion 22 is in the decreasing setting along the sound emitting direction, so that the second noise reduction segment 222 is outwards unfolded relative to the first noise reduction segment 221, and meanwhile, the second noise reduction segment 222 and the first noise reduction segment 221 are in the included angle setting, so that the joint of the second noise reduction segment 222 and the first noise reduction segment 221 can be inwards recessed, so as to increase the volume of the noise reduction cavity 30, improve the noise shielding effect, and make the diameter of the first noise reduction segment 221 smaller, so as to improve the ear comfort of the earphone, and meanwhile, when the second noise reduction segment 222 is far away from the end of the first noise reduction segment 221 and extends out of the accommodating cavity 211, the main body 21 can better support the second noise reduction segment 222, so that the second noise reduction segment 222 is not easy to deform.

Furthermore, the outer side surface of the second noise reduction section 222 and the outer side surface of the first noise reduction section 221 form an included angle of 150 degrees to 160 degrees. The outer side surface of the second noise reduction section 222 and the outer side surface of the first noise reduction section 221 form an included angle of 150 degrees, 155 degrees, 160 degrees, and the like. It can be understood that the larger the included angle formed by the outer side surface of the second noise reduction section 222 and the outer side surface of the first noise reduction section 221 is, the larger the outward expansion degree of the outer side surface of the second noise reduction section 222 relative to the outer side surface of the first noise reduction section 221 is, when the included angle formed by the outer side surface of the second noise reduction section 222 and the outer side surface of the first noise reduction section 221 is too large, the main body 21 may be in too close contact with the ear canal, which may cause discomfort to a user, and when the included angle formed by the outer side surface of the second noise reduction section 222 and the outer side surface of the first noise reduction section 221 is too small, the connection between the second noise reduction section 222 and the main body 21 may not be tight, which may easily cause the sealing failure of the noise reduction cavity 30.
