[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0028] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0029] Embodiment 1

[0030] This embodiment provides a headphone pressure relief hole structure. Referring to Figure 1 , Figure 2 and Figure 3 , it is disposed at the headphone face cover 102 and includes a gear-shaped nut 103 and a pressure relief adjustment component 101.

[0031] The pressure relief adjustment component 101 is installed on the first surface of the headphone face cover 102, the gear-shaped nut 103 is installed on the second surface of the headphone face cover 102. A pressure relief hole 1013 is provided on the pressure relief adjustment component 101, and an opening is provided on the headphone face cover 102. The pressure relief hole 1013 and the opening are opposite in position, and the bottom of the pressure relief adjustment component 101 passes through the opening and is connected to the gear-shaped nut 103.

[0032] In this embodiment, the pressure relief adjustment component 101 and the gear-shaped nut 103 are connected by a threaded structure.

[0033] As a preferred solution of this embodiment, a columnar connecting piece 1012 is provided on the bottom surface of the pressure relief adjustment component 101. A first thread is provided on the outer surface of the columnar connecting piece 1012. A connecting hole 1031 is provided on the gear-shaped nut 103, and a second thread is provided at the connecting hole 1031. The first thread and the second thread are matched, and the pressure relief adjustment component 101 is connected to the gear-shaped nut 103 through the columnar connecting piece 1012 and the connecting hole 1031.

[0034] Meanwhile, the pressure relief hole 1013 longitudinally penetrates through the columnar connecting piece 1012.

[0035] On the other hand, a handle 1011 is installed on the top surface of the pressure relief adjustment component 101.

[0036] Further, the handle 1011 covers above the air vent hole 1013.

[0037] Based on the technical solution of this embodiment, a gear-shaped nut 103 is precisely installed together with the pressure relief adjustment component 101 located on the earphone panel. This process is preferably achieved by matching the pre-set threads on the pressure relief adjustment component 101. Subsequently, the entire pressure relief adjustment component 101 is fixed to the earphone face cover 102. Such an assembly ensures a firm connection between components and provides the necessary structural support for subsequent air release operations.

[0038] Specifically, the combination of the pressure relief adjustment component 101 of the earphone and the gear-shaped nut 103, as well as its fixation to the earphone face cover 102, cooperate with the sound generating unit assembly in the earphone cavity to jointly form a precise pressure relief system. This system realizes fine adjustment of the earphone sound output through the air release from the air vent holes, thereby optimizing the user's auditory experience. At the same time, through the carefully designed pressure relief component, the pressure relief hole structure is fixed by combining the thread with the gear-shaped nut 103. This design effectively manages the sound pressure in the front cavity of the earphone and can also adjust the airtightness of the earphone. Through this adjustment, the tightness between the earphone and the ear canal is optimized, bringing a more comfortable wearing experience. In addition, the handle 1011 is designed on the pressure relief adjustment component 101, which not only simplifies the process of taking off and wearing the earphone but also effectively acts as a dust-proof barrier. Therefore, this design significantly solves the problems of airtightness and usability in traditional customized earphones, improves the quality of frequency response, and thus provides an excellent listening experience. Compared with the existing multi-unit hybrid customized earphones on the market, the solution of this embodiment shows a higher level in terms of wearing comfort and acoustic performance, comprehensively considering the actual usage needs and auditory feelings of users.

[0039] Embodiment 2

[0040] The present utility model also provides an earphone with an earphone pressure relief hole structure. Based on the earphone pressure relief hole structure described in any one of the above, the earphone pressure relief hole structure is provided at the earphone face cover 102 of the earphone.

[0041] Refer to Figure 4 , taking the in-ear monitor customized earphone under parametric design as an example here. The air release function of the earphone is responsible for by the air vent hole 1013 located on the pressure relief adjustment component 101 and the duct hole G located on the inner cavity sound output duct. When the dynamic coil unit emits sound, the sound pressure generated in the front cavity F can escape through the duct hole G on the internal sound output duct and then reach the air vent hole 1013 on the pressure relief adjustment component 101 of the customized earphone for air release operation. By controlling the air flow rate escaping from the pressure relief hole, the adjustment of the internal sound pressure of the earphone can be realized.

[0042] Refer toFigure 5 , another case is a customized in-ear monitor with a dynamic driver and a balanced armature under a manual assembly design. The air leakage function of the earphone is responsible by the air leakage hole 1013 located in the pressure relief adjustment component 101 and the module hole G located in the double-ring opposed bass module. When the dynamic driver DD1 and the dynamic driver DD2 emit sound together, the sound pressure generated in the front cavity F of the double-ring opposed bass module can escape through the module hole G of the double-ring opposed bass module and perform the air leakage operation at the air leakage hole 1013 of the pressure relief adjustment component 101 of the customized earphone. By the air flow rate escaping from the pressure relief hole, the adjustment of the internal sound pressure of the earphone can be achieved.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
