Description

Technical Field

[0001] This utility model relates to the field of headphones, and in particular to a wind noise-canceling headphone and its windproof sticker. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. When you wear open-back headphones on a windy street, the wind is a complex and variable noise source. Even headphones with call noise cancellation technology rely on microphones to capture ambient noise and algorithms to process and eliminate it. However, in strong winds, current algorithms struggle to effectively eliminate all wind noise, so you may still hear a whistling sound during calls. This is normal and not a problem with the headphones themselves.

[0003] When making calls using Bluetooth headsets, wind noise often becomes a source of interference. The direction and intensity of the wind can affect call quality. Especially outdoors, wind can make your voice unclear, impacting call quality or the overall listening experience. Users typically try adjusting the angle or position of the headset to reduce the chance of wind blowing directly on the microphone. While this reduces wind noise, it still makes using the headset inconvenient. Therefore, it's necessary to improve existing headsets. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a wind noise-canceling headset and its windproof sticker, which can effectively solve the problem that existing headsets are easily affected by wind noise, resulting in poor call quality and listening experience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A windproof sticker includes a first windproof layer and a second windproof layer. The second windproof layer is stacked and fixed on the inner wall of the first windproof layer by a first adhesive layer. The inner side of the second windproof layer and the inner wall of the first windproof layer form an entrance cavity. A second adhesive layer is provided on the inner wall of the second windproof layer.

[0007] As a preferred embodiment, both the first adhesive layer and the second adhesive layer are double-sided adhesive.

[0008] As a preferred embodiment, both the first and second windproof layers are made of EVA material.

[0009] As a preferred embodiment, the thickness of both the first windproof layer and the second windproof layer is 1.0 mm.

[0010] As a preferred embodiment, the acoustic cavity includes a buffer section and an acoustic section that are connected sequentially from top to bottom.

[0011] As a preferred embodiment, release paper is bonded and fixed onto the second adhesive layer.

[0012] As a preferred embodiment, the release paper extends outward with an easy-tear portion.

[0013] A wind noise-canceling headphone includes a shell and the aforementioned windproof sticker. The shell has a microphone hole. The windproof sticker is attached to the shell and covers the microphone hole through a second adhesive layer. The inner side of the second windproof layer, the inner wall of the first windproof layer, and the surface of the shell form the aforementioned sound cavity. The opening of the sound cavity faces vertically downward, and the microphone hole communicates with the sound cavity.

[0014] As a preferred embodiment, the outer shell is recessed with a positioning groove, and the aforementioned pore is opened on the end face of the positioning groove. The windproof sticker is attached to the positioning groove and covers the pore through a second adhesive layer.

[0015] As a preferred embodiment, the microphone aperture is connected to the incoming sound segment.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] The second windproof layer is stacked and fixed on the inner wall of the first windproof layer by the first adhesive layer. The second adhesive layer is also provided on the inner wall of the second windproof layer. When the windproof sticker is attached to the earphone shell, the windproof sticker covers the microphone hole. The inner side of the second windproof layer, the inner wall of the first windproof layer and the surface of the shell form the aforementioned sound inlet cavity. When wind noise comes, the windproof sticker protects the microphone hole inside. Most of the wind noise energy is blocked, reflected or absorbed by the first windproof layer. When the person wearing the earphone is talking, the sound waves can be transmitted to the microphone hole through the sound inlet cavity of the windproof sticker without affecting normal voice reception. The installation is simple and can be selectively used according to individual requirements for wind noise. It is also suitable for various types of earphones.

[0032] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a housing 10 and a windproof sticker 20.

[0033] The outer casing 10 has a vent hole 11. In this embodiment, the outer casing 10 has a recessed positioning groove 12. The aforementioned vent hole 11 is located on the end face of the positioning groove 12, and the groove depth of the positioning groove 12 is 0.3 mm or more.

[0034] The windproof patch 20 includes a first windproof layer 21 and a second windproof layer 22. The second windproof layer 22 is stacked and fixed to the inner wall of the first windproof layer 21 by a first adhesive layer 23. The inner side of the second windproof layer 22 and the inner wall of the first windproof layer 21 form a sound inlet cavity 24. A second adhesive layer 25 is disposed on the inner wall of the second windproof layer 22. The windproof patch 20 is attached to the outer shell 10 and covers the microphone hole 11 by the second adhesive layer 25. Specifically, the inner side of the second windproof layer 22, the inner wall of the first windproof layer 21, and the surface of the outer shell 10 form the aforementioned sound inlet cavity 24. The opening of the sound inlet cavity 24 faces vertically downward, and the microphone hole 11 communicates with the sound inlet cavity 24. In this embodiment, both the first adhesive layer 22 and the second adhesive layer 25 are double-sided adhesives, and the first windproof layer 21... Both the first windproof layer 21 and the second windproof layer 22 are made of EVA material, and the thickness of both the first windproof layer 21 and the second windproof layer 22 is 1.0mm. In addition, the sound inlet cavity 24 includes a buffer section 241 and a sound inlet section 242 connected from top to bottom. The microphone 11 is connected to the sound inlet section 242. The design of the buffer section 241 is such that after the wind noise enters from the opening of the sound inlet cavity 24, it does not directly enter the microphone 11 after passing through the sound inlet section 242. Instead, a part of the wind noise enters the buffer section 241 through the sound inlet section 242. This part of the wind noise is weakened after a series of reflections in the buffer section 241 before it can enter the microphone 11. This design further reduces the wind noise. It should be noted that before the windproof sticker 20 is assembled with the outer shell 10, release paper 26 is glued and fixed on the second adhesive layer 25 to prevent dust and other debris from adhering to it. This results in insufficient adhesion of the second adhesive layer 25, and the release paper 26 extends outward with an easy-tear portion 261; and the windproof sticker 20 is attached to the positioning groove 12 through the second adhesive layer 25 and covers the microphone hole 11. The inner side of the second windproof layer 22, the inner wall of the first windproof layer 21, the surface of the outer shell 10 and the end face of the positioning groove 12 together form the aforementioned sound cavity 24.

[0035] The manufacturing process of this embodiment is described in detail below:

[0036] First, peel off the release paper 26. Then, attach the windproof sticker 20 to the end face of the positioning groove 12, so that the inner side of the second windproof layer 22, the inner wall of the first windproof layer 21, the surface of the outer shell 10 and the end face of the positioning groove 12 together form the sound cavity 24.

[0037] The key design feature of this invention is that the second windproof layer is stacked and fixed on the inner wall of the first windproof layer through the first adhesive layer, and the second adhesive layer is also provided on the inner wall of the second windproof layer. When the windproof sticker is attached to the earphone shell, the windproof sticker covers the microphone hole, and the inner side of the second windproof layer, the inner wall of the first windproof layer, and the surface of the shell form the aforementioned sound inlet cavity. When wind noise occurs, the windproof sticker protects the microphone hole inside, and most of the wind noise energy is blocked, reflected, or absorbed by the first windproof layer. When the person wearing the earphone is making a call, the sound waves can be transmitted to the microphone hole through the sound inlet cavity of the windproof sticker without affecting normal voice reception. The installation is simple, and it can be selectively used according to individual requirements for wind noise. It is also suitable for various types of earphones.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
