Please refer to fig. 1, which discloses a schematic structure of a human ear. The human ear 000 is positioned behind the eyes, and has a function of discriminating vibration, converting sound generated by the vibration into a neural signal, and then transmitting the neural signal to the brain. In the brain, these signals are in turn translated into words, music, and other sounds that we can understand. People can distinguish various natural and biological phenomena because of the ears 000; the world can be heard with strange sounds to feel holy. The ear 000 may include structures such as helix 001, helix base 002, antihelix 003, antihelix superior base 004, antihelix inferior base 005, antitragus 006, tragus 007, intertragic notch 008 and external auditory canal 009. Wherein, the crus of the concha 002, the antitragus 006 and the tragus 007 enclose the concha cavity 010.

Unless the context clearly dictates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

Please refer to fig. 2, which discloses a schematic structural diagram of an earphone according to an embodiment of the present application. The headset 100 can be worn on the ear 000 and used as an audio source. Specifically, the earphone 100 may include a main body 10, a sound emitting portion 20, and a grip 30. The main body portion 10 and the sound emitting portion 20 may be case-shaped. The main body 10 and the sound outlet 20 are buckled to form the earphone body. The main body 10 and the sound outlet 20 are engaged to form a receiving space for receiving electronic components inside the earphone 100. The grip 30 is used to facilitate the user's handling of the headset 100. The grip 30 extends from the main body 10 to one side. The electronic components in the earphone 100 generate sound in the receiving space, and the sound can be transmitted from the sound output portion 20.

When the earphone 100 is worn, the sound output portion 20 may be inserted into the external auditory canal 009 and contact the canal wall of the external auditory canal 009, but does not press the canal wall of the external auditory canal 009 nor closely adhere to the canal wall of the external auditory canal 009 to form a sealed state. In the case where the sound emitting portion 20 does not generate a sense of pressure on the wall of the external auditory canal 009, the user can be prevented from feeling uncomfortable with the sense of pressure as a result of the sense of pressure. The main body part 10 is arranged in the concha cavity 010, the main body part 10 can be tightly attached to the auricle wall in the concha cavity 010, and the main body part 10 and the external auditory canal 009 form a closed space to improve the sound effect and improve the listening experience of a user.

The conventional earphones are various and are classified into a flat type, an in-ear type, and a half-in-ear type (shallow in-ear type) according to the form and the depth of insertion into the ear canal. But the flat-top earplug does not have a hermetic seal with the external auditory canal 009. The in-ear and semi-in-ear plugs enter the external ear canal 009 through a portion of the earplug and seal in cooperation with the canal walls of the external ear canal 009. That is, the flat-head earplug can not be effectively sealed with the external auditory canal 009, can appear leaking sound scheduling problem, and can't realize noise reduction effect. The in-ear and shallow-in-ear earplugs are sealed by fitting with the ear canal wall of the external ear canal 009, and since the ear canal wall of the external ear canal 009 has abundant blood vessels and nerves, the sealing of the earplugs with the ear canal wall of the external ear canal 009 may cause a sense of pressure to the external ear canal 009, causing the user to feel uncomfortable distending the ear. While the headset 100 as shown in fig. 2 avoids the problems of the prior art. The earphone 100 is not sealed with the external auditory canal 009, effectively solving the problem of ear expansion when wearing the existing earplug. The earphone 100 does not form a closed space with the external auditory canal 009, which can improve the sound effect and improve the listening experience of the user.

In one embodiment, the headset 100 may be a wired headset. The earphone 100 may be electrically connected to a mobile terminal, such as a mobile phone or a computer, through a data line. The data line is electrically connected to the electronic components of the headset 100.
