[0038] Embodiment 1

[0039] like Figures 1 to 4As shown, the present invention provides an earphone box, which includes a box body 1 and a power generation module 2, the box body 1 is provided with a accommodating cavity 11, the accommodating cavity 11 is used to accommodate an earphone monomer 100, at least part of the outer surface of the box body 1 is provided with a rolling arc surface, and the box body 1 can roll along the rolling arc surface; the power generation module 2 includes a stator component 21 and a rotor component 22, the stator component 21 and the rotor component 22, one includes a conductive coil 221, and the other includes a permanent magnet 211, the stator component 21 is rotatably connected to the box body 1, and the rotor component 22 is fixedly connected to the box body 1, the conductive coil 221 can be electrically connected to the earphone monomer 100 in the accommodating cavity 11, and when the box body 1 rolls along the rolling arc surface, the stator component 21 rotates relative to the rotor component 22 to generate current. In this embodiment, since the box body 1 of the earphone box has a accommodating cavity 11 that matches the earphone monomer 100, the earphone monomer 100 can be stored in the box body 1, so that the user can carry it easily; the earphone box also includes a power generation module 2, and the power generation module 2 includes a stator assembly 21 and a rotor assembly 22. Since the stator assembly 21 includes one of the conductive coil 221 and the permanent magnet 211 and the rotor assembly 22 includes the other of the conductive coil 221 and the permanent magnet 211, the rotation of the stator assembly 21 relative to the rotor assembly 22 can generate an induced electromotive force, thereby generating current in the conductive coil 221, and since the conductive coil 221 can be electrically connected to the earphone monomer 100, the power generation module 2 can The earphone monomer 100 is charged; since at least part of the outer surface of the box body 1 is provided with a rolling arc surface, the box body 1 can roll along the rolling arc surface, and since the rotor assembly 22 is fixedly connected to the box body 1 and the stator assembly 21 is fixedly connected to the box body 1, when the box body 1 rolls, it can drive the rotor assembly 22 to rotate relative to the stator assembly 21, so that an induced current is generated in the conductive coil 221 to charge the earphone monomer 100, and the endurance requirement of the earphone monomer 100 can be met without connecting an external power supply; the earphone box can generate electricity and charge the earphone monomer 100 by rolling itself, has low charging conditions, strong environmental adaptability, good practicality, and is exquisitely designed and interesting.

[0040] It is understandable that the relative rotation of the stator assembly 21 and the rotor assembly 22 to generate current is based on the law of electromagnetic induction, and the current is generated by the conductive coil 221 cutting the magnetic flux lines of the permanent magnet 211; wherein the structure and positional relationship of the conductive coil 221 and the permanent magnet 211 can be set according to actual needs, as long as it can meet the conductive coil 221 cutting the magnetic flux lines when the box body 1 rolls along the rolling arc surface. Exemplarily, the conductive coil 221 and the permanent magnet 211 are both arranged inside the box body 1, and the conductive coil 221 is wound around the outside of the permanent magnet 211 along the length direction of the permanent magnet 211.

[0041] Specifically, Figure 3 and Figure 4As shown, the power generation module 2 further includes a fixed shaft 23 , which is disposed inside the box body 1 and fixedly connected to the box body 1 at both ends, and the stator assembly 21 is rotatably disposed on the fixed shaft 23 . In this embodiment, the stator assembly 21 includes two permanent magnets 211 with opposite magnetic properties, and the two permanent magnets 211 are rotatably arranged on the fixed shaft 23 through bearings. The rotor assembly 22 includes a conductive coil 221 and a mounting shell 222. The mounting shell 222 is a hollow cylindrical shell structure made of magnetic material. The conductive coil 221 is penetrated in the side wall of the mounting shell 222, and the mounting shell 222 is fixed inside the box body 1; the fixed shaft 23 is arranged in the mounting shell 222 along the axial direction of the mounting shell 222, and the two ends of the fixed shaft 23 are respectively fixed on the two end faces of the mounting shell 222, and the angle between the axial direction of the fixed shaft 23 and the rolling axis of the box body 1 is less than 90°; when the box body 1 rolls, the mounting shell 222 will drive the conductive coil 221 mounted on its side wall to move synchronously with the box body 1, while the permanent magnet 211 rotatably arranged on the fixed shaft 23 does not rotate due to inertia or rotates relatively with the mounting shell 222, so that the conductive coil 221 cuts the magnetic flux lines.

[0042] In another embodiment, both ends of the fixed shaft 23 are rotatably connected to the two end surfaces of the mounting shell 222 through bearings, and the permanent magnet 211 is fixedly connected to the fixed shaft 23; when the box body 1 rolls, the mounting shell 222 drives the conductive coil 221 to move synchronously with the box body 1, and the fixed shaft 23 does not rotate due to inertia or rotates relative to the mounting shell 222, thereby causing the conductive coil 221 to cut the magnetic flux lines.

[0043] In order to prevent the earphone unit 100 from escaping from the accommodating cavity 11, Figure 2 As shown, a magnetic attraction member 111 is provided in the accommodating cavity 11 , and the magnetic attraction member 111 is used to attract the earphone monomer 100 , so that the earphone monomer 100 can be stably and firmly attracted in the accommodating cavity 11 under the action of magnetic force.

[0044] like Figure 1 and Figure 2 As shown, the accommodating cavity 11 is recessed in the outer surface of the box body 1. When the earphone monomer 100 is placed in the accommodating cavity 11, the end surface of the earphone monomer 100 facing away from the box body 1 smoothly transitions to the outer surface of the box body 1. Therefore, the earphone monomer 100 can serve as a part of the box body 1 and together with the outer surface of the box body 1 form a complete earphone box surface. The earphone monomer 100 can be covered and protected without setting up a flip cover. The storage is convenient and the maintenance cost is low. In addition, the end surface of the earphone monomer 100 smoothly transitions to the outer surface of the box body 1, which greatly increases the area of ​​the rolling arc surface, making the box body 1 smoother and more stable when rolling.

[0045] Furthermore, if Figure 1 and Figure 3As shown, a stationary plane 12 is provided on the outer surface of the box body 1. When the earphone box needs to be placed stably, the user can place the earphone box on a desktop or a cabinet through the stationary plane 12 to keep the earphone box still.

[0046] In order to improve the stability of the earphone box when it is placed still, an anti-skid pad is provided on the stationary plane 12. The anti-skid pad is made of a flexible material and has a high friction coefficient, which can improve the stability of the earphone box.

[0047] Furthermore, if Figure 2 and Figure 4 As shown, the earphone box further includes a push mechanism 3, which is disposed on the box body 1 and can drive the earphone monomer 100 to leave the accommodating cavity 11. Since the end surface of the earphone monomer 100 facing away from the box body 1 smoothly transitions with the outer surface of the box body 1, the push mechanism 3 is provided to drive the earphone monomer 100 to leave the accommodating cavity 11, thereby avoiding the inconvenience of taking out caused by the smooth splicing of the end surface of the earphone monomer 100 and the outer surface of the box body 1, and the earphone monomer 100 can be taken out of the accommodating cavity 11 without the user's fingers lifting, which greatly facilitates the user.

[0048] The structure of the push mechanism 3 can be set according to actual needs, as long as it can assist the user to take the earphone unit 100 out of the accommodating cavity 11. Figure 3 and Figure 4 As shown, the pushing mechanism 3 includes a pushing member 31 and a control button 32. The pushing member 31 is arranged inside the box body 1, and the control button 32 is arranged on the outer surface of the box body 1. The control button 32 is electrically connected to the pushing member 31. Pressing the control button 32 can drive the pushing member 31 to push the earphone unit 100 in a direction away from the accommodating cavity 11. The pushing member 31 can be a micro cylinder commonly used in the field, or it can be a micro electric push rod. In this embodiment, the push member 31 is a miniature electric push rod, and its built-in motor is electrically connected to the control button 32. Pressing the control button 32 can control the push rod of the push member 31 to extend or retract through the built-in motor; when the earphone monomer 100 needs to be taken out, the user presses the control button 32, and the built-in motor of the push member 31 receives the signal and extends the push rod to push the earphone monomer 100 outward, so that the end face of the earphone monomer 100 protrudes from the outer surface of the box body 1, and the earphone monomer 100 is magnetically attracted by the magnetic attraction member 111 and will not fall out of the accommodating cavity 11, thereby making it easy for the user to take it; when putting the earphone monomer 100 back, the user needs to press the control button 32 again to control the push member 31 to retract the push rod, and then put the earphone monomer 100 into the accommodating cavity 11.

[0049] In this embodiment, if Figure 1 and Figure 2As shown, the box body 1 is spherical and can roll in any direction and angle. However, only when the angle between the rolling axis of the box body 1 and the axis of the fixed axis 23 is less than 90°, the conductive coil 221 can cut the magnetic flux lines and generate current. The spherical box body 1 enhances the comfort of human hand holding and is more interesting.

[0050] Furthermore, if Figure 3 and Figure 4 As shown, the earphone box also includes a battery 4, which is arranged inside the box body 1. The battery 4 is electrically connected to the conductive coil 221. The battery 4 is used to charge the earphone unit 100 in the accommodating cavity 11. The battery 4 can store electrical energy and charge the earphone unit 100, thereby further improving the battery life of the earphone box.

[0051] Specifically, the conductive coil 221 can be electrically connected only to the battery 4, in which case the conductive coil 221 is used to charge the battery 4, and the battery 4 charges the earphone unit 100 in the accommodating cavity 11; the conductive coil 221 can also be electrically connected to both the battery 4 and the earphone unit 100 in the accommodating cavity 11, in which case both the conductive coil 221 and the battery 4 can charge the earphone unit 100.

[0052] This embodiment also provides an earphone device, which includes an earphone unit 100 and the earphone box, and the earphone unit 100 can be accommodated in the accommodating cavity 11 of the box body 1 to form a rolling arc surface. The earphone device is exquisitely designed, easy to hold, and has strong interest. At the same time, it can generate electricity by rolling, which greatly facilitates the user.

[0053] Embodiment 2

[0054] like Figure 5 As shown, this embodiment provides an earphone box, which is basically the same as the earphone box in the first embodiment, and the main difference is that the box body 1 is cylindrical. In order to improve the stability and smoothness of the box body 1 rolling, specifically, the box body 1 is a regular cylinder, the side of the box body 1 is its rolling arc surface, and the two end surfaces are static planes 12; when the earphone box needs to be rolled to charge the earphone monomer 100, the user rolls the earphone box along the side of the box body 1, and the box body 1 drives the conductive coil 221 in the rotor assembly 22 to cut the magnetic flux line, thereby generating electricity and charging the earphone monomer 100 in the accommodating cavity 11.

[0055] In order to fully convert the mechanical energy of the earphone box rolling into electrical energy, the fixed axis 23 is arranged inside the box body 1 parallel to the axis of the box body 1. When the box body 1 rolls along its side, it can synchronously drive the conductive coil 221 to rotate around the axis of the fixed axis 23 relative to the permanent magnet 211 on the fixed axis 23.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
