Abstract
Description
Technical Field
[0001] The invention relates to an earphone structure, and in particular to a wireless charging earphone. Background Art
[0002] In order to avoid the restrictions of wires, time-consuming wire rewinding, and line damage, wireless headphones have gradually replaced traditional wired headphones for listening to music, talking, watching videos, and playing games. Nowadays, wireless headphones are equipped with induction coils inside, giving them wireless charging functions.
[0003] However, the wireless headset has a front shell placed on the ear on one side and an exposed back shell on the other side. The induction coil is mainly fixed in the middle of the inner side of the back shell. In order for the induction coil to perform electromagnetic induction stably, the electromagnetic induction needs to be evenly attached to the charging plate or without interference from other electronic components, resulting in the back shell being unable to be designed with curved surfaces, inclined surfaces, etc. or to install other electronic components (such as display lights, buttons, etc.).
[0004] In view of this, the inventor has devoted himself to studying the above-mentioned prior art and has applied the theory to try his best to solve the above-mentioned problems, which has become the goal of the inventor's development. Summary of the invention
[0005] The present invention provides a wireless charging headset, which utilizes a ring-shaped wireless charging module to be arranged between a front housing and a speaker module, so that the wireless charging headset has good design, assembly convenience and operation stability.
[0006] In an embodiment of the present invention, the present invention provides a wireless charging headset, comprising: an earphone shell, having a front shell and a cavity, the front shell being provided with a plurality of sound holes; a speaker module, accommodated in the cavity and configured corresponding to the plurality of sound holes; and an annular wireless charging module, accommodated in the cavity, the annular wireless charging module being arranged between the front shell and the speaker module.
[0007] Based on the above, the annular wireless charging module is arranged between the front shell and the speaker module. Since no other electronic components are installed near the position of the front shell, the operation of the annular wireless charging module will not be affected by the speaker module or other electronic components, and the appearance design of the rear shell and the configuration of electronic components (such as display lights, buttons, etc.) do not need to be changed due to the constraints of the annular wireless charging module, thereby improving the design, assembly convenience and operational stability of the wireless charging headset.

[0035] The detailed description and technical contents of the present invention will be described as follows with reference to the accompanying drawings, however, the drawings are only for illustrative purposes and are not intended to limit the present invention.
[0036] Please refer to Figures 1 to 5 As shown, the present invention provides a wireless charging headset. The wireless charging headset 10 mainly includes one or more headset housings 1, one or more speaker modules 2 and one or more ring-shaped wireless charging modules 3.
[0037] like Figures 1 to 5 As shown, the earphone housing 1 comprises a front housing 11 and a rear housing 12 which are arranged opposite to each other, the front housing 11 is provided with a plurality of sound outlets 111, and the earphone housing 1 has a cavity s inside. The front housing 11 is used to be placed on the ear of the user.
[0038] like Figure 3 As shown, the speaker module 2 is accommodated in the cavity s and is arranged corresponding to a plurality of sound outlet holes 111 , so that the sound generated by the speaker module 2 can be transmitted to the outside of the front housing 11 through the sound outlet holes 111 .
[0039] like Figures 1 to 5 As shown, the annular wireless charging module 3 is accommodated in the cavity s, and the annular wireless charging module 3 is arranged between the front shell 11 and the speaker module 2, and is arranged around the periphery of the speaker module 2 to avoid blocking the sound generated by the speaker module 2.
[0040] The detailed description is as follows: the annular wireless charging module 3 is fixed to the front housing 11 and is arranged around the periphery of the sound holes 111 so that the annular wireless charging module 3 will not block the sound holes 111, so that the sound generated by the speaker module 2 can be smoothly transmitted to the sound holes 111.
[0041] In addition, the annular wireless charging module 3 of the present embodiment includes an annular circuit board 31 and an annular magnetic resonance coil 32 mounted on the annular circuit board 31 . The annular magnetic resonance coil 32 is fixedly connected to the surface of the annular circuit board 31 adjacent to the front housing 11 .
[0042] Furthermore, the annular magnetic resonance coil 32 is a ring-shaped magnetic resonance coil, which uses "magnetic resonance" for wireless charging. Compared with "electromagnetic induction", the "magnetic resonance" method can allow the charging distance to reach several meters and the charging efficiency is also improved.
[0043] like Figure 3As shown, the wireless charging headset 10 of the present invention further includes one or more control modules 4, which are accommodated in the cavity s. The control module 4 includes a control circuit board 41 and a battery 42. The control circuit board 41 is electrically connected to the speaker module 2, the annular circuit board 31 and the battery 42 respectively. Figure 1 , Figures 4 to 5 As shown, the wireless charging headset 10 of the present invention further includes a bracket 5. The number of the headset housing 1, the speaker module 2, the annular wireless charging module 3 and the control module 4 of this embodiment are two respectively. Each speaker module 2, the annular wireless charging module 3 and the control module 4 are respectively accommodated in the cavity s of each headset housing 1, and the two headset housings 1 are respectively assembled at the two ends of the bracket 5. The shape of the bracket 5 is U-shaped, so that the bracket 5 is suitable for wearing on the top of the head, the back of the head or the back of the neck of the human body, but it is not limited to this. Figure 1 , Figures 4 to 5 As shown, the wireless charging headset 10 of the present invention further includes two rotating shafts 6 , which are assembled between two ends of the bracket 5 and the two earphone housings 1 . Each earphone housing 1 can rotate relative to the bracket 5 via each rotating shaft 6 .
[0044] like Figures 3 to 5 The wireless charging headset 10 of the present invention is used in a state where the front housing 11 is rotated outward by the rotating shaft 6 using the housing 1 of the headset, and then the front housing 11 is placed on the charging plate 100. The transmitting end induction coil 101 in the charging plate 100 transmits wireless power according to the "magnetic resonance" theory. The transmitting end induction coil 101 vibrates at a resonant frequency and emits an alternating magnetic field to the surroundings. The annular magnetic resonance coil 32 of the annular wireless charging module 3 senses the alternating magnetic field and converts it into alternating current. Finally, the alternating current is stored in the battery 42 via the annular circuit board 31 and the control circuit board 41. The control circuit board 41 then powers other electronic components such as the speaker module 2 through the battery 42.
[0045] In addition, the conventional induction coil is mainly fixed at the middle of the inner side of the back shell, which makes it impossible to design the back shell with curved surfaces, inclined surfaces, etc. or install other electronic components (such as display lights, buttons, etc.). In contrast, the annular wireless charging module 3 of the wireless charging headset 10 of the present invention is arranged between the front shell 11 and the speaker module 2 and is arranged around the periphery of the speaker module 2. Since no other electronic components are installed near the position of the front shell 11, the annular wireless charging module 3 will not be affected by the speaker module 2 or other electronic components in operation, and the appearance design of the rear shell 12 and the configuration of electronic components (such as display lights, buttons, etc.) do not need to be changed by the annular wireless charging module 3, thereby improving the design, assembly convenience and operation stability of the wireless charging headset 10.
[0046] Please refer to Figure 6 FIG. 2 is another embodiment of the wireless charging headset 10 of the present invention. Figure 6 Examples and Figures 1 to 5 The embodiments are roughly the same. Figure 6 Examples and Figures 1 to 5 The embodiment is different in that the structure of the ring-shaped wireless charging module 3 is different.
[0047] The details are as follows. The annular circuit board 31 of this embodiment is fixed to the front shell 11. A groove 311 is provided on the surface of the annular circuit board 31 adjacent to the front shell 11. The annular magnetic resonance coil 32 is embedded in the groove 311 so that the annular magnetic resonance coil 32 is more firmly fixed on the annular circuit board 31.
[0048] Please refer to Figure 7 As shown, another embodiment of the wireless charging headset 10 of the present invention is shown. Figure 7 Examples and Figures 1 to 5 The embodiments are roughly the same. Figure 7 Examples and Figures 1 to 5 The embodiment is different in that the structure of the ring-shaped wireless charging module 3 is different.
[0049] Further description is as follows: the annular circuit board 31 of this embodiment is fixed to the front housing 11 , a groove 311 ′ is formed on the outer periphery of the annular circuit board 31 , and the annular magnetic resonance coil 32 is embedded in the groove 311 ′ so that the annular magnetic resonance coil 32 is more firmly fixed on the annular circuit board 31 .
[0050] Please refer to Figure 8 FIG. 1 is another embodiment of the wireless charging headset 10 of the present invention. Figure 8 Examples and Figures 1 to 5 The embodiments are roughly the same. Figure 8 Examples and Figures 1 to 5 The embodiment is different in that the structure of the ring-shaped wireless charging module 3 is different.
[0051] The details are as follows: the annular wireless charging module 3 of this embodiment omits the components of the annular circuit board 31 (such as Figures 1 to 5 As shown in FIG. 1 ), the annular wireless charging module 3 only includes an annular magnetic resonance coil 32 ′ fixedly connected to the front housing 11 , and the annular magnetic resonance coil 32 ′ is electrically connected to the control circuit board 41 , so that the annular wireless charging module 3 has the advantages of reducing components and saving costs.
