Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless earphone technology, specifically to a wireless earphone with a dustproof structure. Background Technology
[0002] With the development of technology, wireless headphones have become widely popular due to their convenience. However, in daily use, wireless headphones are easily invaded by dust, especially in dusty environments such as outdoors or construction sites. Dust entering the headphones may affect the sound quality, damage internal components, or even cause malfunctions, shortening their lifespan. Furthermore, when wireless headphones are turned off, the contact between the earbuds and the charging case produces a crisp sound, which can disturb those nearby. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a wireless earphone with a dustproof structure, which has the advantage of dustproof protection and solves the problems mentioned in the background technology.
[0004] To achieve the above-mentioned dustproof purpose, this utility model provides the following technical solution: a wireless earphone with a dustproof structure, including an earphone case body and two earphone bodies, wherein two earphone slots are provided inside the earphone case body, and an earphone cover is hinged to the upper rear part of the earphone case body;
[0005] Two arc-shaped blocks are provided at the rear of each earphone slot. A rotating frame is rotatably mounted in the middle of each arc-shaped block. A dust cover is installed on the upper end of each rotating frame. A transparent film is provided in the middle of each dust cover.
[0006] As a further improvement of this utility model: a second sealing strip is provided at the bottom of the earphone cover, and a first sealing strip is provided at the bottom of the dust cover. Both the first and second sealing strips are made of silicone material. The second sealing strip improves the sealing performance of the contact surface between the earphone cover and the earphone case body, preventing moisture and dust from entering the earphone case body. It can also reduce noise when the earphone cover contacts the earphone case body, preventing loud noise and not disturbing the rest of people around.
[0007] As a further improvement of this utility model: a protective pad is provided on the outside of the earphone case body. The protective pad is made of rubber material and can protect the surface of the earphone case body to prevent scratches.
[0008] As a further improvement of this utility model: a buffer pad is provided at the bottom of the inner side of the protective pad, which can cushion the bottom of the earphone box body and play a protective role.
[0009] As a further improvement of this utility model: a hanging port is provided in the middle of the front wall of the protective pad, through which the headphone box body can be easily hung to achieve portability.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] In this invention, by covering the two dust covers, the first sealing strip increases the sealing performance with the outer ring of the earphone slot, improves the dust and water resistance, and prevents the earphone body from falling off and being lost. Then, by covering the earphone cover, the second sealing strip improves the sealing performance of the contact surface between the earphone cover and the earphone case body, preventing moisture and dust from entering the earphone case body. It also reduces noise when the earphone cover contacts the earphone case body, avoiding loud noise and not disturbing the rest of the surrounding people. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-4 In this embodiment of the utility model, a wireless earphone with a dustproof structure includes an earphone box body 1 and two earphone bodies 11. The earphone box body 1 has two earphone slots 4 inside, and an earphone cover 6 is hinged to the upper rear part of the earphone box body 1.
[0019] Two arc-shaped blocks 9 are provided at the rear of the earphone slot 4. A rotating frame 10 is rotatably mounted in the middle of the arc-shaped block 9. A dust cover 5 is installed on the upper end of the rotating frame 10. A transparent film 7 is provided in the middle of the dust cover 5.
[0020] The headphone cover 6 has a second sealing strip 13 at its bottom, and the dust cover 5 has a first sealing strip 8 at its bottom. Both the first sealing strip 8 and the second sealing strip 13 are made of silicone. The second sealing strip 13 improves the sealing of the contact surface between the headphone cover 6 and the headphone case body 1, preventing moisture and dust from entering the headphone case body 1. It also reduces noise when the headphone cover 6 contacts the headphone case body 1, preventing loud noise and avoiding disturbing the rest of the surrounding people. The headphone case body 1 has a protective pad 3 on its outside. The protective pad 3 is made of rubber and can protect the surface of the headphone case body 1 from scratches. The bottom of the inner end of the protective pad 3 has a cushioning pad 12, which can cushion the bottom of the headphone case body 1 and provide protection. The protective pad 3 has a hanging hole 2 in the middle of the front wall of the front end, which allows the headphone case body 1 to be hung for easy portability.
[0021] The working principle of this utility model is as follows: Insert the two earphone bodies 11 into the corresponding earphone slots 4, and then cover them with two dust covers 5. The first sealing strip 8 increases the sealing with the outer ring of the earphone slot 4, improves the dust and water resistance, and prevents the earphone bodies 11 from falling off and being lost. Then cover them with the earphone cover 6. The second sealing strip 13 improves the sealing of the contact surface between the earphone cover 6 and the earphone case body 1, preventing moisture and dust from entering the earphone case body 1. It can also reduce noise when the earphone cover 6 contacts the earphone case body 1, preventing loud noise. Charge the earphone case body 1 through the charging interface. The earphone case body 1 can be easily hung through the hanging port 2. The protective pad 3 can protect the surface of the earphone case body 1 to prevent scratches, and the buffer pad 12 can cushion the bottom of the earphone case body 1, playing a protective role.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
