[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a Bluetooth headset structure with waterproof film protection, including an earphone body 1 and a waterproof breathable membrane 3, wherein the waterproof breathable membrane 3 covers the port of the sound outlet tube 2 of the earphone body 1, both ends of the waterproof breathable membrane 3 are bent inwardly and extend along the outer wall of the sound outlet tube 2, and are both equipped with adjustment plates 4 for pulling the waterproof breathable membrane 3, and limit blocks 5 are installed on both sides of the end face of the sound outlet tube 2 facing the waterproof breathable membrane 3.

[0023] In this embodiment, adjustment grooves 7 are axially provided on the top and bottom surfaces of the sound outlet tube 2, and adjustment blocks 9 are installed on the inner side surfaces of the adjustment plate 4 opposite to the adjustment grooves 7. The adjustment blocks 9 are slidably set in the adjustment grooves 7. A plurality of clamping grooves 8 are provided on the inner wall surfaces of the adjustment grooves 7. Clamping blocks 10 are protruded on the opposite surfaces of the adjustment blocks 9. The clamping blocks 10 are inserted into the corresponding clamping grooves 8 and are clamped and fixed with the clamping grooves 8.

[0024] In this embodiment, the cross-sections of the adjusting groove 7 and the adjusting block 9 are both arranged in a trapezoidal structure, so that the adjusting block can only move along the axial direction of the adjusting groove, thereby avoiding direct separation from the adjusting groove.

[0025] In this embodiment, the middle of the sound outlet tube 2 protrudes to form a plurality of limiting parts 6 for clamping the earplugs. The limiting parts 6 are arranged on both sides of the waterproof breathable membrane 3, so that after the earplugs are put on the sound outlet tube, they can be clamped with the limiting parts to fix the ear frame.

[0026] In this embodiment, the adjustment plates 4 are all arranged in an arc-shaped structure, and the arc degree of the adjustment plates 4 is the same as the arc degree of the outer arc of the sound outlet tube 2. The inner side surfaces of the adjustment plates 4 are in contact with the outer wall surface of the sound outlet tube 2, so that the adjustment plates can only move along the axial direction of the sound outlet tube, avoiding rotation and deviation, and increasing stability.

[0027] In this embodiment, the width of the waterproof breathable membrane 3 is greater than the width of the sound outlet hole on the sound outlet tube 2, so that the waterproof breathable membrane can fully cover the sound outlet hole to achieve a waterproof effect.

[0028] In this embodiment, the limit block 5 and the sound outlet pipe 2 are integrally injection molded, and the distance between the limit blocks 5 matches the width of the waterproof breathable membrane 3, which can position the waterproof breathable membrane at one end located in front of the sound outlet pipe to the left and right, thereby increasing stability.

[0029] During installation, the waterproof breathable membrane can cover the front of the sound outlet pipe, and the adjustment plate can be slidably arranged in the adjustment groove through the adjustment block until the card block on the adjustment block is inserted into the corresponding card slot, thereby fixing the waterproof breathable membrane on the sound outlet pipe. The waterproof breathable membrane can effectively intercept water vapor, preventing water vapor from entering the interior of the earphone body, thereby increasing safety and providing waterproof protection.

[0030] Among them, after long-term use, a section of the waterproof breathable membrane located in front of the sound outlet pipe is prone to blockage or excessive impurities. In order to ensure the sound quality effect, the upper adjustment plate can be pulled outward to make the waterproof breathable membrane in a loose state. At this time, the lower adjustment plate can be pulled toward the earphone body to tighten the loose waterproof breathable membrane again, and the section that has been used for a long time and blocked can be removed, and the section of the waterproof breathable membrane that has not been used before can be moved to the front of the sound outlet pipe to ensure the sound transmission effect. After the movement, the card block can be inserted into the corresponding card slot again to position the moved adjustment plate;

[0031] When not needed, the adjustment block can be directly removed from the adjustment slot to complete the disassembly and replacement of the waterproof breathable membrane.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
