[0029] To describe in detail the technical content, achieved objectives and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.
[0030] Please refer to Figures 1-11, the present utility model provides a technical solution: a walkie-talkie, including a housing, a battery 16, a first circuit board 11, a second circuit board 32 and an antenna 15. The housing is composed of a lower housing 1 and an upper housing 2;
[0031] The battery 16 is in a flat shape and is arranged in a stacked manner with the first circuit board 11, and the battery 16 is electrically connected to the first circuit board 11;
[0032] The first circuit board 11 is located inside the housing near the inner side wall of the lower housing 1;
[0033] The antenna 15 is vertically placed inside the housing relative to the first circuit board 11, and one end of the antenna 15 is welded to the second circuit board 32;
[0034] The first circuit board 15 is electrically connected to the second circuit board 32;
[0035] The antenna 15 is a bent spring antenna, and the bent part is far away from the first circuit board 11;
[0036] A Z-shaped light guide plate 20 is installed on the first circuit board 11.
[0037] From the above description, the beneficial effect of the present utility model is that by adopting a bent spring antenna, the effective length of the antenna can be increased in a limited space, thereby enhancing the radiation and reception capabilities of the antenna, which helps to improve the signal coverage, signal strength and stability of the walkie-talkie, so that good communication quality can be maintained in long-distance communication or environments with weak signals.
[0038] Further, a first receiving groove 23 is provided at the bottom of the Z-shaped light guide plate 20;
[0039] An LED lamp 19 is installed between the first circuit board 11 and the Z-shaped light guide plate 20;
[0040] The LED lamp 19 is located inside the first receiving groove 23.
[0041] From the above description, by arranging the LED lamp 19 inside the first receiving groove 23, the light flux path can be changed to the greatest extent, so that the light is conducted from the bottom to the top along the route of the Z-shaped light guide plate.
[0042] Further, a transparent decorative member 6 is installed at the top of the Z-shaped light guide plate 20;
[0043] The shape of the transparent decorative member 6 is a frustum of a cone;
[0044] The upper housing 2 is provided with a limiting hole 13, and the diameter of the limiting hole 13 is larger than the minimum diameter of the transparent decorative member 6 and smaller than the maximum diameter of the transparent decorative member 6;
[0045] The transparent decorative member 6 is exposed from the upper housing 2 through the limiting hole 13.
[0046] As can be seen from the above description, the transparent decorative member 6 is exposed from the upper housing 2 through the limiting hole 13. The LED lamp 19 generates bright light, and the light changes its path under the action of the Z-shaped light guide plate 20 and is displayed through the transparent decorative member 6. The light displayed by the transparent decorative member 6 is more likely to be noticed by the user. At the same time, the LED lamp 19 is not exposed outside the upper housing 2, which can play a waterproof role to a certain extent.
[0047] Furthermore, a first positioning hole 26 is provided at the position of the LED lamp 19 on the Z-shaped light guide plate 20, and a first positioning post 24 is provided on the inner side of the upper housing 2. The first positioning post 24 is inserted into the inner side of the first positioning hole 26.
[0048] A second positioning hole 27 is provided at the position of the transparent decorative member 6 on the Z-shaped light guide plate 20, and a second positioning post 25 is provided on the inner side of the upper housing 2. The second positioning post 25 passes through the second positioning hole 27.
[0049] As can be seen from the above description, the positioning post also plays a limiting role and can prevent the displacement of the Z-shaped light guide plate and the transparent decorative member during daily use.
[0050] Furthermore, a sound pickup hole 8 is provided on one side of the bottom of the lower housing 1.
[0051] A second receiving groove 28 is provided on the inner side of the bottom of the lower housing 1, and a microphone is installed in the second receiving groove 28. The microphone receives external sounds through the sound pickup hole 8.
[0052] As can be seen from the above description, both the microphone and the sound pickup hole 8 are provided at the bottom of the lower housing 1. During the use process by the user, this area is closer to the user's mouth, which is convenient for collecting and receiving the user's voice.
[0053] Furthermore, an earplug 5 is provided on one side of the lower housing 1.
[0054] A clamping protrusion 21 is provided at the end of the connecting end of the earplug 5.
[0055] An annular clamping groove 22 is provided on the inner side wall of the lower housing 1, and a limiting block 29 is provided in the annular clamping groove 22.
[0056] The earplug 5 is movably connected to the inner side of the annular clamping groove 22 through the clamping protrusion 21.
[0057] As can be seen from the above description, the earplug 5 is movably connected to the inner side of the annular engaging groove 22 through the engaging protrusion 21. On the premise of keeping the position of the earplug 5 unchanged, the user is allowed to adjust the position of the sound pickup hole 8 so that it fits the most comfortable position of different users, enabling the walkie-talkie to better adapt to the needs of different users and environmental changes.
[0058] Furthermore, a speaker 9 is provided inside the earplug 5, and the speaker 9 is electrically connected to the first circuit board 11 through a through hole 30.
[0059] As can be seen from the above description, the speaker 9 is electrically connected to the first circuit board 11 through the through hole 30. When rotating the outer shell of the walkie-talkie, the winding of the internal wires will be avoided.
[0060] Furthermore, a conductive spring 14 is connected to the first circuit board 11, and a touch area 4 is provided on the outer surface of the upper shell 2 on one side of the conductive spring 14;
[0061] A conductive cloth 31 is bonded to the inner wall of the upper shell 2 at the position of the conductive spring 14.
[0062] As can be seen from the above description, when the user touches the touch area 4, the sensed signal can be transmitted to the conductive cloth 31, so that the conductive spring 14 conveys the signal to the circuit board, thereby completing the intercom function of the walkie-talkie; the PTT key corresponding to the touch area 4 is a commonly used key of the walkie-talkie and adopts a non-mechanical structure. This product has good waterproof performance and relatively stable sensitivity.
[0063] Furthermore, the touch area 4 is provided with granular protrusions 35.
[0064] As can be seen from the above description, when the user touches the touch area 4, the area of the touch area 4 can be easily recognized through the granular protrusions 35 on the touch area 4, improving the user experience.
[0065] Furthermore, a third positioning hole 33 is formed on the second circuit board 32, and a third positioning post 34 is provided inside the lower shell 1. The third positioning post 34 is inserted into the inner side of the third positioning hole 33.
[0066] As can be seen from the above description, the positioning post also plays a limiting role and can prevent the displacement of the antenna 15 during daily use.
[0067] Working principle: When a walkie-talkie is needed, first hang the ear hook 7 on the outside of the ear and insert the earplug 5 into one side of the ear canal. At this time, when the user touches the touch area 4 with a finger, the first circuit board 11 can be controlled to work, thereby realizing the intercom function of the walkie-talkie. At the same time, the button group 3 respectively has volume control and power switch control, and the volume size and the switch of the walkie-talkie can be controlled through the button group 3. At this time, the speaker 9 inputs the sound into the inner side of the user's ear, and at the same time, the microphone inside the sound pickup hole 8 receives the user's voice;
[0068] When it is necessary to adjust the position of the sound pickup hole 8 on one side of the lower housing 1 of the walkie-talkie, only the outer shell needs to be rotated. At this time, the engaging protrusion 21 slides inside the annular engaging groove 22, and the limiting block 29 inside the annular engaging groove 22 causes the engaging protrusion 21 on one side of the earplug 5 to slide at an angle of about 30 degrees, adjusting the position of the sound pickup hole 8 so that the walkie-talkie can better adapt to the needs of different users and environmental changes;
[0069] At the same time, when the first circuit board 11 is working, the LED lamp 19 generates light at this time. The light changes its route under the action of the Z-shaped light guide plate 20 and is displayed through the transparent decorative member 6. The maximum size of the transparent decorative member 6 is larger than the size of the LED lamp 19, and the light diffuses in the transparent decorative member 6, forming a larger luminous area, making the light displayed by the transparent decorative member 6 easier to be noticed by users, improving the overall use experience. At the same time, the LED lamp 19 is not exposed on one side of the upper housing 2, which can play a waterproof role to a certain extent and extend the service life of the device;
[0070] The antenna 15 on one side of the first circuit board 11 is bent. Inside the same upper housing 2, an antenna 15 with a longer length can be inserted, making the signal transceiver effect of the walkie-talkie better;
[0071] When the battery power of the walkie-talkie is insufficient, the charger is inserted inside the charging connector 10. At this time, the charging connector 10 charges the battery 16;
[0072] In summary, by adopting the bent spring antenna 15, the effective length of the antenna 15 can be increased in a limited space, thereby enhancing the radiation and reception capabilities of the antenna 15, which helps to improve the signal coverage, signal strength and stability of the walkie-talkie, enabling good communication quality to be maintained even in long-distance communication or environments with weak signals. The bent antenna 15 can be more compactly installed between the first circuit board 11 and the upper housing 2, effectively utilizing the limited space, not only reducing the interference of other components' antennas inside the device to 15, but also making the overall structure of the walkie-talkie more compact, lightweight, and convenient to carry and use;
[0073] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are equally included in the patent protection scope of the present invention.
