Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art. It should be understood that the embodiments described below are only some embodiments of the invention, and not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive step, without departing from the spirit and scope of the present invention as defined and defined by the appended claims, belong to the protection scope of the present invention.

As shown in fig. 1, 2 and 3, the self-generating type bluetooth headset comprises a body 1, a magnetic induction module is arranged in a vertical end 2 of the body 1, the magnetic induction module comprises a first magnet 6, second magnet and third magnet 9, first magnet 6 and the fixed setting of second magnet 7 are in erecting end 2, vertical suspension under the interact of first magnet 6 and third magnet 9 of second magnet 7, be provided with coil 8 in the magnetic induction line scope of second magnet 7, whole or partial second magnet 7 is encircleed to the middle part heliciform of coil 8, the fixed setting in middle part of coil 8, coil 8's output and rectifier module 5's input are connected, rectifier module 5's output and energy collection module 4's input are connected, energy collection module 4's output is connected with electric energy storage module 3's input, electric energy storage module 3's the output and body 1's play system is connected.

The working principle of the utility model is as follows: the second magnet 7 is driven by the walking action of the user to break the original balance, and moves up and down, so that the total magnetic flux passing through the coil 8 is changed, and an induced current is formed. The induced current is converted into direct current after passing through the rectifying module 5, and then the electric energy is collected and stored through the energy collecting module 4 and the electric energy storage module 3 to supply power for the playing system.

When in use, the user can wear the utility model on the head. In addition, when the outdoor user does not use the electric charger, the electric charger can be worn on the head or hung on a backpack, and the charging process is carried out.

As shown in fig. 3, the first magnet, the second magnet 7, and the third magnet 9 are cylindrical magnets, and are located on the same straight line. The N-pole of the first magnet 6 is disposed opposite to the N-pole of the second magnet 7 so that the second magnet 7 is kept in levitation by the repulsive force of the first magnet 6 and the second magnet 7. By adopting the arrangement, the magnetic induction module occupies a smaller volume, and simultaneously ensures that the coil 8 has larger magnetic flux change in the process of shaking the second magnet 7 up and down under the action of external force, thereby ensuring the generated energy.

Wherein, first magnet 6 and third magnet 9 are diameter 10mm, thickness 2 mm's neodymium iron boron magnet, and second magnet 7 is diameter 10mm, thickness 10 mm's neodymium iron boron magnet, and the interval between first magnet 6 and the third magnet 9 is 32 mm. In the static state, the second magnet 7 and the third magnet are spaced apart by 10 mm. The diameter of the coil is 0.5mm, and the inner diameter of a circle formed by enclosing a single coil is 15 mm. The coil had 60 turns with the center points thereof spaced 17mm and 15mm from the first magnet 6 and the third magnet 9, respectively. When the gait frequency of the pedestrian is 60 to 100/min, the charging voltage of the storage battery can reach 4.8 to 5.2 v. In addition, in order to further restrict the motion track of the second magnet 7 and enhance the stability of the earphone, a circular plastic tube with a smooth inner wall is fixedly arranged in the earphone, and the circular plastic tube takes the central point of the coil as the center, and has an inner diameter of 12mm, an outer diameter of 14mm and a height of 32 mm.

For the convenience also can charge for electric energy storage module 3 when quiescent condition, electric energy storage module 3's input and the USB interface connection that charges, the USB interface that charges is located the surface of body 1, utilizes the USB interface that charges for its quick charge, has enlarged its range of application.
