[0018] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by terms such as “upper”, “lower”, “front”, “rear”, “left”, “right”, “inside”, “outside”, “vertical” and “circumferential” are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The hand-cranked power-generating headset of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Combined with Figure 1-3The specific implementation process of the hand-cranked power-generating headset of the present invention is as follows:

[0022] A hand-cranked headphone mainly comprises a headphone body 1 and a hand-cranked power generation mechanism 2. The headphone body 1 comprises two left and right earmuffs 6 for wrapping the user's ears and providing audio output. The hand-cranked power generation mechanism 2 is cleverly integrated on the outside of one of the earmuffs 6, which does not affect the wearing comfort and can be easily operated.

[0023] The hand-cranked generator mechanism 2 is composed of a hand-cranked component 3, a generator 4 and a rectifier circuit 5. The hand-cranked component 3 is arranged on the outside of an earmuff 6 of the headset body 1, and extends into the inside of the earmuff 6, and is connected to the generator 4 through a transmission shaft 11. The user can drive the generator 4 to rotate and generate electricity by turning the hand-cranked component 3.

[0024] The hand crank assembly 3 specifically includes a handle 9, a handle 10 and a transmission shaft 11. The handle 9 is disposed at the top of the handle 10 and is rotatably connected to the handle 10, so that the user can hold and rotate it. The transmission shaft 11 is disposed at the bottom of the handle 10 and is responsible for transmitting the rotational torque to the generator 4.

[0025] The electric energy generated by the generator 4 is first processed by the rectifier circuit 5. The rectifier circuit 5 includes a rectifier unit 13, a filter unit 14 and a voltage reducer 15, which rectifies, filters and reduces the voltage of the electric energy in sequence to ensure that the output is stable and meets the voltage requirements of the control circuit board 7. The rectified electric energy is transmitted to the power module 8 of the control circuit board 7 in the earmuff 6 of the headphone body 1.

[0026] The control circuit board 7 is integrated with a Bluetooth music receiving MP3 mainboard 16, which supports Bluetooth connection to mobile phones or other audio devices to achieve wireless music playback. At the same time, the earmuffs 6 are also provided with a number of control buttons 17 electrically connected to the control circuit board 7, which are convenient for users to adjust the volume, switch songs, etc.

[0027] In order to optimize the power generation efficiency, a reducer 12 is further provided inside the earmuff 6, and the transmission shaft 11 is connected to the three-phase brushless generator 4 through the reducer 12. The reducer 12 can reduce the rotation speed and increase the torque, thereby increasing the output efficiency of the generator 4.

[0028] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
