Description

Technical Field

[0001] The utility model relates to the technical field of earphone design, in particular to a wireless earphone stacking structure and a wireless earphone. Background Art

[0002] Wireless earphones, which eliminate the need for wires, are popular among people of all ages and backgrounds (especially drivers and athletes). Antennas are key components for wireless transmission.

[0003] Since wireless earphones are small in size, there is not much space left for antennas after PCB boards, batteries and other components are placed inside the housing of the wireless earphones. Figure 3 As shown, in the existing wireless headset, the battery, PCB board and antenna are stacked in sequence in the height direction of the shell. The large battery volume seriously encroaches on the height space inside the shell, which undoubtedly causes the antenna and the PCB board to be too close. The antenna's clearance area is seriously insufficient, which affects the antenna's radiation effect, resulting in a serious decline in the communication quality of the wireless headset, bringing a poor experience to users.

[0004] Therefore, finding a technical solution that can solve the above technical problems has become an important topic studied by those skilled in the art. Utility Model Content

[0024] The utility model discloses a wireless headset stacking structure and a wireless headset, which are used to solve the technical problem that the distance between the antenna and the PCB in the existing wireless headset is relatively close, resulting in insufficient clearance area of the antenna, causing poor radiation effect of the antenna and thus affecting call quality.

[0025] To help those skilled in the art better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a portion of the present invention, not all of the embodiments. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 2 , an embodiment of the present utility model provides a wireless headset stacking structure, including a housing 1, a battery 3, a PCB board 2 and an antenna 4;

[0027] The battery 3, the PCB board 2 and the antenna 4 are installed inside the shell 1, and the battery 3 and the antenna 4 are electrically connected to the PCB board 2. The battery 3 and the PCB board 2 are at a first horizontal height of the shell 1, and the antenna 4 is at a second horizontal height of the shell 1.

[0028] In the stacked structure of the wireless headset of this embodiment, the battery 3 and PCB board 2 are located at a first level within the housing 1, while the antenna 4 is located at a second level within the housing 1. This design ensures that the battery 3 and PCB board 2 are at the same height, so the larger battery 3 does not encroach on the height space of the housing 1. This leaves sufficient clearance between the antenna 4 and the PCB board 2, effectively enhancing the radiation effect of the antenna 4 and improving the communication quality of the wireless headset.

[0029] Furthermore, the battery 3 in this embodiment is located on the side of the PCB board 2 , and the battery 3 is arranged parallel to the PCB board 2 .

[0030] It should be noted that the battery 3 in this embodiment can be specifically arranged on the front side, left side, right side, or rear side of the PCB board 2. Designers can choose a suitable installation position according to actual conditions, and this embodiment does not impose any restrictions on this.

[0031] Furthermore, the distance between the antenna 4 and the PCB board 2 in this embodiment ranges from 2.5 mm to 4 mm.

[0032] It should be noted that the distance between the antenna 4 and the PCB board 2 in this embodiment can be 2.5 mm, 3 mm, 4 mm, etc., among which the preferred distance between the antenna 4 and the PCB board 2 is 3 mm.

[0033] Furthermore, the PCB board 2 in this embodiment has a first surface and a second surface that are arranged opposite to each other, wherein the antenna 4 is located above the first surface or the antenna 4 is located below the second surface.

[0034] It should be noted that the PCB board 2 in this embodiment has a certain thickness. Therefore, the PCB board 2 has a first surface and a second surface that are relatively arranged in its thickness direction. It can be simply understood that the first surface is the front side of the PCB board 2 and the second surface is the back side of the PCB board 2. In this embodiment, the antenna 4 can be set above the first surface or below the second surface. The designer can select the specific installation position of the antenna 4 according to actual design requirements.

[0035] Furthermore, the housing 1 in this embodiment protrudes in a direction away from the PCB board 2 to form an accommodating cavity on its inner side wall;

[0036] The antenna 4 is located in the accommodating cavity.

[0037] It should be noted that through the above design, the internal space of the shell 1 can be further expanded, and the antenna 4 can be placed in the above-mentioned accommodating cavity, which can further increase the distance between the antenna 4 and the PCB board 2, thereby increasing the clearance area of the antenna 4 and further improving the radiation effect of the antenna 4.

[0038] Furthermore, the wireless headset stacking structure in this embodiment further includes a first conductive wire and a second conductive wire;

[0039] The battery 3 is electrically connected to the PCB board 2 through the first conductive wire, and the antenna 4 is electrically connected to the PCB board 2 through the second conductive wire.

[0040] It should be noted that in this embodiment, the antenna 4, battery 3 and PCB board 2 are electrically connected by wire connection. This design can avoid the antenna 4 being electrically connected to the PCB board 2 by welding, which causes the distance between the antenna 4 and the PCB board 2 to be too close, thereby reducing the clearance area of the antenna 4.

[0041] Furthermore, the antenna 4 in this embodiment is a plate-shaped structure antenna 4 .

[0042] It should be noted that, preferably, the antenna 4 in this embodiment can be a flat plate structure or a curved plate structure that fits the inner wall of the housing 1 , thereby further increasing the clearance area of the antenna 4 .

[0043] See also Figure 1 and Figure 2 , an embodiment of the present invention provides a wireless headset, including the above-mentioned wireless headset stacking structure.

[0044] In the wireless headset of this embodiment, the battery 3 and PCB board 2 are located at a first level within the housing 1, while the antenna 4 is located at a second level within the housing 1. This design ensures that the battery 3 and PCB board 2 are at the same height, so the larger battery 3 does not encroach upon the height space of the housing 1. This leaves sufficient clearance between the antenna 4 and the PCB board 2, effectively enhancing the radiation effect of the antenna 4 and improving the communication quality of the wireless headset.

[0045] The above is a detailed introduction to a wireless headset stacking structure and a wireless headset provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
