DETAILED DESCRIPTION

[0021] In the related art, not only FPC needs to be attached on the inner wall surface of the OWS earphone shell, but also an LDS engraved antenna needs to be passed through. However, the inner wall surface of the OWS earphone shell has a large number of structural features, which makes the clearance of the FPC and the antenna insufficient. On the one hand, it will greatly limit the layout and direction of the antenna, and on the other hand, it will cause the antenna to be too close to other electronic elements or metal components in the shell, which is easy to cause electromagnetic interference, ultimately affecting the radiation efficiency and signal transceiving ability of the antenna, and reducing the antenna performance of the OWS earphone. In view of this, the present application proposes an OWS earphone shell and an OWS earphone in the following embodiments to solve the above-mentioned drawbacks existing in the related art.

[0022] In order to make the purpose, technical scheme and advantages of the present application more obvious and easy to understand, the present application will be described clearly and completely below in combination with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. It should be understood that the embodiments of the present application described below are only used to explain the present application and do not limit the present application, that is, based on the various embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0023] Please refer to Figure 1 , Figure 1is a structural schematic diagram of an OWS earphone shell. The embodiment provides an OWS earphone shell, which comprises a front shell 1 and a rear shell 2, the front shell 1 and the rear shell 2 are connected and surrounded to form a containing cavity 3, the containing cavity 3 is used for containing a PCB (i.e. a printed circuit board, not shown in the figure), an inner wall of the rear shell 2 is used for attaching an FPC (i.e. a flexible circuit board, not shown in the figure) electrically connected with the PCB, an outer wall of the rear shell 2 is laser-engraved with an antenna (not shown in the figure), at least one end of the antenna penetrates into the rear shell 2 and is used for electrically connecting the FPC, that is, the electrical connection between the antenna and the PCB is established through the FPC, and the antenna is mainly used for transmitting and receiving wireless signals, so as to realize the functions of wireless connection (such as WiFi and Bluetooth), wireless communication, intelligent interaction (such as wireless charging and interaction with Xiaoai and Xiaodu), positioning and navigation of the OWS earphone. In addition, it should be noted that the containing cavity 3 is not only used for containing the PCB and the FPC, but also used for containing other devices required for the operation of the OWS earphone in the art, such as microphones, sensors and sound generating units, etc., which will not be enumerated one by one in the embodiment. It should be further noted that the material of the OWS earphone shell can be plastic (such as ABS plastic, PC plastic and PP plastic), metal (such as aluminum alloy and stainless steel), composite material (such as carbon fiber composite material and glass fiber composite material) and the like, which can be selected according to actual needs, and the embodiment does not make a unique limitation thereto.

[0024] In the embodiment, the PCB is actually the core circuit carrier of the OWS earphone, which can integrate Bluetooth chips, audio decoding chips, power management chips and the like, so as to provide stable circuit connection and signal transmission for various function implementations of the OWS earphone; at the same time, the PCB also has good mechanical strength and electrical performance, which can ensure the stability and reliability of the OWS earphone in the long-term use process, and is suitable for carrying circuit modules with high requirements for performance and stability.

[0025] In the embodiment, the OWS earphone needs to realize multiple functions in a limited space, and the flexible characteristics of the FPC enable it to flexibly wire in a narrow and irregular space, adapt to the complex structure inside the OWS earphone, such as bending and folding the FPC to make it fit the shape of the OWS earphone shell and connect electronic components at different positions, so as to fully utilize the space and realize a more compact design. Specifically, the FPC can be used to connect the PCB and the antenna, the sound generating unit, the microphone, the sensor and the like, and in order to reduce interference in the signal transmission process, short-distance and high-frequency signal transmission also needs to be realized through the FPC to ensure accurate transmission of audio signals and control signals. In addition, the FPC has a certain flexibility, which can to some extent play a role in shock absorption, reduce the influence of shaking, collision and the like in the wearing process of the OWS earphone on circuit connection, and at the same time, through reasonable design and shielding measures, the FPC can also effectively reduce the mutual interference between signals and improve the performance of the OWS earphone.

[0026] As can be seen from the above, compared with the traditional scheme in which the FPC and the antenna are both arranged on the inner wall of the rear shell 2, the antenna is etched on the outer wall of the rear shell 2 in the embodiment, which can improve the clearance of the FPC and the antenna (the value of the increased antenna clearance is equal to the wall thickness of the rear shell 2), is more conducive to the wiring and debugging of the antenna, and can also avoid electromagnetic interference caused by the proximity of the antenna to other electronic elements or metal components in the rear shell 2, thereby improving the radiation efficiency and signal transceiving capability of the antenna, and further improving the antenna performance of the OWS earphone (experimentally verified, the antenna performance can be improved by more than 1.5 db), and the ID size of the OWS earphone (the space size of the OWS earphone shell for accommodating various electronic elements and structures) can also be smaller.

[0027] In some embodiments, referring to Figure 2 and Figure 3 , Figure 2 is an exploded view of the OWS earphone shell from one perspective, Figure 3 is an exploded view of the OWS earphone shell from another perspective; the front shell 1 has a first shell opening 11 which is in communication with the inside, the rear shell 2 has a second shell opening 21 which is in communication with the inside, and when the front shell 1 and the rear shell 2 are in abutment, the first shell opening 11 and the second shell opening 21 are connected.

[0028] Further, a plurality of first connecting pieces 4 are arranged on the periphery of the first shell opening 11, a plurality of second connecting pieces 5 are arranged on the periphery of the second shell opening 21, and when the front shell 1 and the rear shell 2 are in abutment, the plurality of first connecting pieces 4 are matched with the plurality of second connecting pieces 5 respectively, so that the front shell 1 and the rear shell 2 are relatively fixed, thereby reducing the risk of separation of the front shell 1 and the rear shell 2 during use of the OWS earphone and ensuring the stability of the abutment of the front shell 1 and the rear shell 2. Exemplarily, the first connecting piece 4 and the second connecting piece 5 each include three, one of the three first connecting pieces 4 is located at one end of the front shell 1, the other two first connecting pieces 4 are respectively located at opposite sides of the front shell 1, one of the three second connecting pieces 5 is located at one end of the rear shell 2, the other two second connecting pieces 5 are respectively located at opposite sides of the rear shell 2, and the three first connecting pieces 4 correspond to the three second connecting pieces 5 one by one, so as to realize the matching of the three first connecting pieces 4 with the three second connecting pieces 5 respectively.

[0029] As one or more of the embodiments, the first connecting member 4 is a buckle 41, and the second connecting member 5 is a buckle groove 51, so that the front shell 1 and the rear shell 2 are stably connected by the buckling cooperation of the buckle 41 and the buckle groove 51. Of course, in other embodiments, the first connecting member 4 can be a buckle groove 51, and the second connecting member 5 can be a buckle 41. The specific setting can be based on actual needs, and the present application does not make a unique limitation. Preferably, taking the first connecting member 4 as a buckle 41 and the second connecting member 5 as a buckle groove 51 as an example, the buckle 41 is a protrusion extending outward from the periphery of the first shell opening 11, and the buckle groove 51 is a groove recessed inward from the periphery of the second shell opening 21, and the two are compatible in shape.

[0030] In some embodiments, referring to Figure 2 , the outer wall of the rear shell 2 includes a non-threading area 22 and at least one threading area 23 other than the non-threading area 22, the thickness of the threading area 23 is less than the thickness of the non-threading area 22, and the at least one threading area 23 is used for the at least one end of the antenna to pass into the rear shell 2, so that the antenna is electrically connected with the FPC. It can be understood that the purpose of the thickness of the threading area 23 being less than the thickness of the non-threading area 22 is to facilitate the end of the antenna to pass into the rear shell 2 through the threading area 23. Preferably, the length of the threading area 23 is greater than 0.6 mm, the width is greater than 0.6 mm, and the thickness is 0.3-0.5 mm; for example, the length, width and thickness of the threading area 23 are 1 mm, 0.8 mm and 0.35 mm respectively, the thickness of the non-threading area 22 is 0.7 mm, and since the value added by the antenna clearance is the wall thickness of the rear shell 2, the antenna clearance is increased by 0.7 mm.

[0031] As one or more of the embodiments, a threading hole (not shown in the figure) is formed in the threading area 23 and communicates with the inside of the rear shell 2, and the threading hole is used for the end of the antenna to pass into the rear shell 2, so that the antenna is electrically connected with the FPC. Preferably, the diameter of the threading hole is 0.15-0.5 mm, such as 0.2 mm.

[0032] In the one or more embodiments, a hole sealing member (not shown in the figure) is arranged in the threading hole, and the hole sealing member is used to seal the threading hole. Illustratively, the hole sealing member includes any one of a glue block and a metal block. It can be understood that in the chemical plating process of the laser-engraved antenna, the chemical solution will deposit metal in the threading hole, and eventually form a metal block in the threading hole, thereby achieving the sealing of the threading hole, and ensuring that the subsequent gluing process (i.e. the process of integrating the glue layer 7 described below) will not shrink; of course, after the end of the antenna is passed into the rear shell 2 through the threading hole, a hard glue such as silicone glue can be injected into the threading hole, and a glue block is formed after the glue is solidified, thereby also achieving the sealing of the threading hole.

[0033] Referring to Figure 4 and Figure 5 ,Figure 4 is a structural schematic diagram of an OWS earphone, Figure 5 is an exploded schematic diagram of an OWS earphone. The embodiment provides an OWS earphone, which comprises a core wire (not shown in the figure), a shape memory steel wire (not shown in the figure), a battery shell 6, a battery (not shown in the figure), a PCB (not shown in the figure), an FPC (not shown in the figure) and the OWS earphone shell described above, the battery is arranged in the battery shell 6, the PCB and the FPC are arranged in the OWS earphone shell, the FPC is attached to the inner wall of the rear shell 2 in the OWS earphone shell, one end of the shape memory steel wire is inserted into the battery shell 6 and the other end is inserted into the OWS earphone shell, one end of the core wire is inserted into the battery shell 6 and electrically connected to the battery, the other end of the core wire is inserted into the OWS earphone shell and electrically connected to the PCB, that is, the electrical connection between the battery and the PCB is established through the core wire, the shape memory steel wire and the core wire both present a preset radian bending, at least one end of the antenna engraved on the outer wall of the rear shell 2 penetrates into the rear shell 2 and is electrically connected to the FPC, and the FPC is electrically connected to the PCB, that is, the electrical connection between the antenna and the PCB is established through the FPC.

[0034] It can be understood that the shape memory steel wire and the core wire both present a preset radian bending, because this part needs to be used as an ear hook of the OWS earphone to facilitate the user to wear. In the embodiment, the outer surfaces of the rear shell 2, the core wire, the shape memory steel wire and the battery shell 6 are coated with a glue layer 7, the glue layer 7 is integrally formed, the glue layer 7 is, for example, a silica gel layer, a rubber layer, a polyurethane glue layer, a hot melt glue layer, an acrylic ester glue layer and the like, and the specific selection can be made according to the actual needs, and the embodiment does not make a unique limitation. In addition, it should be noted that the material of the battery shell 6 can be plastic (such as ABS plastic, PC plastic and PP plastic), metal (such as aluminum alloy and stainless steel), composite material (such as carbon fiber composite material and glass fiber composite material) and the like, and the embodiment does not make a unique limitation.

[0035] The above embodiments are only preferred implementations of the present application, and are not the only limitations of the OWS earphone shell and the OWS earphone. Based on the above embodiments, a person skilled in the art can flexibly set according to the actual application scene.

As can be seen, compared with the conventional scheme in which the FPC and the antenna are both arranged on the inner wall of the rear shell 2, the present application laser-engraves the antenna on the outer wall of the rear shell 2, which can improve the clearance of the FPC and the antenna (the value of the increased antenna clearance is equal to the wall thickness of the rear shell 2), is more conducive to the wiring and debugging of the antenna, and can also avoid the electromagnetic interference caused by the too close distance between the antenna and other electronic elements or metal components in the rear shell 2, thereby improving the radiation efficiency and signal transmitting and receiving capability of the antenna, and further improving the antenna performance of the OWS earphone (it is verified by experiments that the antenna performance can be improved by more than 1.5 db).
