The glue sealing operation is complicated, the cost is high, the quality control is poor, and the glue has a time limit. After a long time, the glue is aged or debonded, resulting in a high possibility of water ingress. Due to the limitations of the gluing process equipment on the production line, it is necessary to disassemble the parts at the bottom of the ear handle, which has a high cost and can easily lead to reduced sealing performance.

[0007] Therefore, how to achieve a long-term stable waterproof effect of the headphone microphone, improve the waterproof performance of the headphone microphone, and facilitate the installation of the headphone microphone and the waterproof structure is a technical problem faced by technical personnel in this field.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Please refer to Figure 1 , Figure 1 The present invention provides a schematic diagram of the overall structure of a specific implementation method.

[0033] In a specific implementation manner provided by the present invention, the microphone waterproof mounting module mainly includes a mounting groove 2, a mounting bracket 3, a microphone 4, a waterproof patch 5, an elastic arm 6 and a first positioning column 7.

[0034] The mounting groove 2 is provided at the end of the earphone housing 1 to facilitate receiving the user's voice signal. The mounting bracket 3 is detachably arranged in the mounting groove 2. The mounting bracket 3 is generally concave in shape and has an inner end face 3a, an outer end face 3b and two side walls.

[0035] The microphone 4 is attached to the inner end surface 3a of the mounting bracket 3, and the waterproof patch 5 is attached to the outer end surface 3b of the mounting bracket 3. The two generally remain opposite to each other, and the outer end surface 3b of the mounting bracket 3 also remains opposite to and abuts against the inner end surface of the mounting groove 2, thereby pressing the waterproof patch 5 between the outer end surface 3b of the mounting bracket 3 and the inner end surface of the mounting groove 2.

[0036] It is important that a recessed groove 21 is provided on the inner side wall of the mounting groove 2, and an elastic arm 6 is provided on the side wall of the mounting bracket 3, and a first positioning column 7 is also provided on the elastic arm 6. The first positioning column 7 is mainly used to abut against the recessed groove 21 under the elastic reaction force of the elastic arm 6, thereby forming a snap fit with the recessed groove 21, and the elastic arm 6 and the mounting bracket 3 are firmly installed in the mounting groove 2. At the same time, by relying on the fixation of the mounting bracket 3, the outer end face 3b of the mounting bracket 3 and the inner end face of the mounting groove 2 are strengthened and maintained to press and abut, thereby positively (vertically) pressing the waterproof patch 5 to prevent the waterproof patch 5 from being displaced or loosened, so that it can stably exert its waterproof effect, ensure the long-term and stable waterproof effect of the microphone, and improve the waterproof performance of the headphone microphone.

[0037] In a preferred embodiment of the waterproof patch 5, the waterproof patch 5 is specifically a composite layer component, mainly including an elastic waterproof layer 51, a waterproof filter layer 52 and a double-sided adhesive layer 53, which are overlapped and tightly combined into one. Among them, one side surface (outer surface) of the elastic waterproof layer 51 is attached to the outer end surface 3b of the mounting bracket 3, the waterproof filter layer 52 is attached between the elastic waterproof layer 51 and the double-sided adhesive layer 53, and one side outer surface (outer surface) of the double-sided adhesive layer 53 is attached to the inner end surface of the mounting groove 2. The elastic waterproof layer 51, the waterproof filter layer 52 and the double-sided adhesive layer 53 can all be in the shape of a circular plate, and a central through hole can be opened in the central area of ​​the elastic waterproof layer 51 and the double-sided adhesive layer 53 to facilitate the transmission of sound waves to the microphone 4.

[0038] Specifically, the elastic waterproof layer 51 can be an elastic waterproof foam, which is elastic and has the maximum waterproof effect when it is positively (vertically) pressed, and the positive contact between the outer end surface 3b of the mounting bracket 3 and the inner end surface of the mounting groove 2 can keep the elastic waterproof layer 51 positively pressed. The waterproof filter layer 52 can be a waterproof mesh, which not only has a waterproof effect, but also can filter out impurities in water or air. The double-sided adhesive layer 53 can be a double-sided tape, one side of which is stably attached to the waterproof filter layer 52, and the other side of which is stably attached to the inner end surface of the mounting groove 2.

[0039] In order to facilitate the first positioning column 7 to smoothly form a snap fit with the sink 21 during the installation of the mounting bracket 3, the present embodiment further provides a track groove 22 of a certain length and a preset track on the inner side wall of the mounting groove 2. The track groove 22 is mainly used for the first positioning column 7 to slide during its installation stroke, and the end of the track groove 22 is connected to the opening of the sink 21. With such a configuration, during the installation of the mounting bracket 3, the first positioning column 7 can gradually slide in the track groove 22 to achieve the gradual installation of the mounting bracket 3 in the mounting groove 2, until the first positioning column 7 slides to the end of the track groove 22 and forms a snap fit with the sink 21, and the mounting bracket 3 is installed and fixed in the mounting groove 2.

[0040] At the same time, in order to ensure that the outer end surface 3b of the mounting bracket 3 can positively abut the waterproof patch 5, in this embodiment, the end of the track groove 22 is perpendicular to the inner end surface of the mounting groove 2, and of course, it is also perpendicular to the outer end surface of the mounting groove 2. Generally, since the waterproof patch 5 is tightly attached to the outer end surface 3b of the mounting bracket 3, when the first positioning column 7 slides to its end along with the track groove 22 and cooperates with the sink 21, the movement direction of the mounting bracket 3 can be kept perpendicular to the waterproof patch 5, thereby achieving vertical abutment with the waterproof patch 5.

[0041] like Figure 5 As shown, Figure 5 for Figure 1 The specific structural schematic diagram of the track groove 22 is shown in FIG.

[0042] Furthermore, in order to facilitate the first positioning column 7 to slide smoothly into the track groove 22 at the beginning of installation, in this embodiment, the first end opening of the track groove 22 can be directly opened at the top position of the inner side wall of the installation groove 2 to form a top through structure. At the same time, the first end opening of the track groove 22 can face the vertical (height) direction, which is convenient for the installation bracket 3 to be smoothly installed into the installation groove 2 in the horizontal direction.

[0043] Since the opening of the first end of the track groove 22 faces the vertical direction, and the opening of the end of the track groove 22 faces the horizontal direction, the middle area of ​​the track groove 22 needs to transition at an angle of about 90°. Therefore, in this embodiment, the track groove 22 can be a curved groove with a smooth wall transition. In this way, the track groove 22 can be curved as a whole, and the first positioning column 7 can slide smoothly to the end along the groove wall of the track groove 22.

[0044] In addition, this embodiment also opens a chamfer 10 at the opening of the head end of the track groove 22 and the sink groove 21 at the end, and also opens a chamfer 10 at the top of the first positioning column 7 (and the subsequent second positioning column 8). With this arrangement, the inclination angle of the chamfer 10 can make it easier for the first positioning column 7 (and the second positioning column 8) to slide into the track groove 22 or the sink groove 21.

[0045] In order to improve the installation stability and balance of the mounting bracket 3 during the installation process, and to avoid the mounting bracket 3 from shaking and causing deviation from the waterproof sticker 5, in this embodiment, the sink groove 21 and the track groove 22 can be distributed on both sides of the inner wall of the mounting groove 2, and the sink grooves 21 and the track grooves 22 on both sides are axially symmetrically distributed. Similarly, in this embodiment, the elastic arm 6 and the first positioning column 7 can be distributed on both sides of the outer wall of the mounting bracket 3, and the elastic arm 6 and the first positioning column 7 on both sides are axially symmetrically distributed. Of course, the sink groove 21 and the track groove 22, the elastic arm 6 and the first positioning column 7 can also be set on one side.

[0046] like Figure 2-Figure 3 , Figure 6 As shown, Figure 2 for Figure 1 The specific structural diagram of the mounting bracket 3 is shown in FIG. Figure 3 for Figure 2 Another perspective diagram, Figure 6 for Figure 2 A schematic diagram of the specific structure of the first positioning column 7 and the second positioning column 8 is shown in FIG.

[0047] In addition, considering that during the sliding of the first positioning column 7 in the track groove 22, the gravity of the mounting bracket 3 itself may have an adverse effect on the instantaneous movement direction or movement posture of the mounting bracket 3, resulting in deviation, in view of this, the second positioning column 8 is also erected on the outer walls of both sides of the mounting bracket 3 in this embodiment. Specifically, the shape of the second positioning column 8 can be the same as that of the first positioning column 7, but since it does not need to cooperate with the sink 21, the height can be slightly lower. The second positioning column 8 can be specifically set at the top corner position of the mounting bracket 3, and the first positioning column 7 can be specifically located at the bottom corner position of the mounting bracket 3, and the two are diagonally distributed - this distribution form is the same as the distribution form of the head end opening and the end position of the track groove 22. In this way, when the first positioning column 7 slides a certain distance in the track groove 22, the second positioning column 8 also slides into the track groove 22 at the same time, so that the movement direction or posture of the mounting bracket 3 in the installation stroke is adjusted through the abutment force between the second positioning column 8 and the groove wall of the track groove 22 to prevent the movement direction from deviating, and ensure that when the first positioning column 7 slides to the end of the track groove 22 and the sink groove 21 forms a snap fit, the outer end surface 3b of the mounting bracket 3 can positively abut the waterproof sticker 5. Figure 4 As shown, Figure 4 It is a schematic diagram of the installation process of the mounting bracket 3 in the mounting groove 2.

[0048] In order to facilitate the installation of the elastic arm 6 and the first positioning column 7, a strip through hole is provided on the outer wall of the mounting bracket 3 in this embodiment, and the strip through hole can extend horizontally along the width direction of the mounting bracket 3. At the same time, one end of the elastic arm 6 can be connected to one side wall of the strip through hole and extend to the other side wall of the strip through hole. The first positioning column 7 can be vertically arranged on the end surface of the elastic arm 6 and extend outward by a certain length. Generally, the elastic arm 6 can be flush with the outer wall surface of the mounting bracket 3 or deviate outward from the strip through hole by a certain angle in a natural state. When the mounting bracket 3 starts to be installed in the mounting groove 2, the elastic arms 6 on both sides are abutted by the side walls of the mounting groove 2, so that the elastic arms 6 are elastically compressed. When the first positioning column 7 slides to the end position of the track groove 22, the abutment effect of the side wall of the mounting groove 2 disappears. Under the elastic reaction force of the elastic arm 6, the first positioning column 7 is ejected into the sink 21 at the end of the track groove 22 to form a snap fit with it.

[0049] In addition, in order to improve the structural strength of the mounting bracket 3, the present embodiment connects reinforcing ribs 9 between the inner end surface 3a of the mounting bracket 3 and the inner walls on both sides thereof, thereby enhancing the connection stability and structural strength between the inner end surface 3a of the mounting bracket 3 and the inner walls on both sides thereof through the action of the reinforcing ribs 9.

[0050] This embodiment also provides an earphone, which mainly includes an earphone housing 1 and a microphone waterproof mounting module arranged in the earphone housing 1, wherein the specific content of the microphone waterproof mounting module is the same as the above-mentioned related content and is not repeated here. The earphone described in this embodiment refers to a wireless Bluetooth earphone or a TWS earphone.

[0051] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
