[0048] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0050] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0051] Ginseng Figure 1 The present application discloses an earphone 100. The earphone 100 includes a housing 10, a speaker 20 disposed within the housing 10, a ventilation duct 30, an inflatable earplug 40, and a control assembly 50. At least a portion of the ventilation duct 30 is disposed within the housing 10. The inflatable earplug 40 is connected to the ventilation duct 30 and is detachably disposed outside the housing 10. The control assembly 50 is disposed outside the housing 10 and is used to inflate or deflate the inflatable earplug 40 through the ventilation duct 30.

[0052] In this application, a portion of the space within the housing 10 is used as a ventilation duct 30, which is then connected to the inflatable earplug 40. A control assembly 50 is then used to inflate and deflate the inflatable earplug 40, thereby adjusting the size of the inflatable earplug 40 according to the size of the user's ear canal. Thus, compared to prior art earphones that come with earplugs of varying sizes, the earphones 100 of this application do not require additional earplugs. The size of the inflatable earplug 40 can be adjusted to the size of the user's ear canal to achieve optimal listening experience, effectively reducing the manufacturing cost of the earphones 100 and being more environmentally friendly. Furthermore, the inflatable earplug 40 is detachably mounted on the outside of the housing 10 for easy replacement.

[0053] Ginseng Figure 1 and Figure 2 The housing 10 is provided with a receiving chamber 11. The receiving chamber 11 is provided with an isolating portion 12. The isolating portion 12 separates the receiving chamber 11 into a sound channel 111 and the ventilation duct 30. The speaker 20 is provided in the sound channel 111.

[0054] Ginseng Figure 1 and Figure 2 The housing 10 includes a front end 101 and a rear end 102 away from the front end 101. The sound channel 111 and the ventilation duct 30 both extend from the rear end 102 toward the front end 101. The inflatable earplug 40 is sleeved on the front end 101.

[0055] In this embodiment, Figure 1 and Figure 2The inflatable earplug 40 is in a hollow ring structure, and a through hole 401 is formed in a substantially middle position of the inflatable earplug 40. In this way, the inflatable earplug 40 is sleeved on the front end 101 through the through hole 401. That is, the front end 101 is sleeved in the through hole 401. At this time, part of the air passage 30 and part of the sound passage 111 are located in the through hole 401 of the inflatable earplug 40.

[0056] In other embodiments, the position where the through hole 401 is formed on the inflatable earplug 40 can not be limited to the middle position, but can also be a position close to the edge, etc.

[0057] Further, referring to Figure 1 The earphone 100 further comprises a fitting piece 60. The fitting piece 60 is connected to the connection between the inflatable earplug 40 and the air passage 30, and is used to cooperate with the control assembly 50 to inflate or deflate the inflatable earplug 40. At the same time, the fitting piece 60 is also used to ensure the air tightness of the inflatable earplug 40 when the inflatable earplug 40 is not inflated or deflated, so as to avoid the leakage of the gas entering the inflatable earplug 40.

[0058] Specifically, referring to Figure 1 And Figure 2 A first opening 104 is formed in the shell 10 and communicates with the air passage 30. A second opening 402 is formed in the inflatable earplug 40 and cooperates with the first opening 104. The fitting piece 60 is arranged in the first opening 104 and the second opening 402.

[0059] Referring to Figure 1 And Figure 2 The control assembly 50 comprises a pump 501. The pump 501 is connected to the air passage 30 and is located in the rear end 102. The pump 501 inflates the inflatable earplug 40 through the air passage 30 and the fitting piece 60, so as to adjust the size of the inflatable earplug 40 according to the size of the ear canal of the user.

[0060] Further, the control assembly 50 further comprises a deflation valve 502. The deflation valve 502 is connected to the air passage 30 and is located in the rear end 102. The deflation valve 502 deflates the inflatable earplug 40 through the air passage 30 and the fitting piece 60, so as to further adjust the size of the inflatable earplug 40 according to the size of the ear canal of the user.
