As shown in fig. 1 and fig. 2, the wireless headset kit of the present embodiment includes a wireless headset 10 and a headset charging box 40, or adds accessories such as a charger and a data line on the basis.

The wireless headset 10 preferably includes a left headset and a right headset, each having a handset 11 and an in-ear 12. The hand-held part 11 is internally provided with a rechargeable battery 13, and the shell is provided with electrodes for connecting external power supply to charge the rechargeable battery 13. A speaker (not shown) is disposed in the ear insertion portion 12, and a sound output hole is formed in the housing for inserting into an ear canal to output sound waves when in use.

The earphone charging case 40 preferably includes a body 30 and a case cover 20 rotatably coupled to the body 30. Wherein, two earphone chambers 31 are formed in the body 30 for inserting a left earphone and a right earphone, respectively. An electrode spring is arranged in the earphone chamber 31 and is used for being in contact conduction with an electrode on the wireless earphone 10. The battery 32 is installed in the body 30, and is used for charging the rechargeable battery 13 in the wireless earphone 10 through the contact-conducted electrode spring and the electrode when the wireless earphone 10 is inserted into the earphone chamber 31, so as to achieve the design purpose of replenishing electric quantity to the wireless earphone 10 while accommodating the wireless earphone 10.

In order to realize the function of automatically opening the cover on the earphone charging box 40, in this embodiment, a pair of magnetic elements, which may specifically include an electromagnet 33 and a permanent magnet 23, are added to the earphone charging box 40, and for clarity of description, the pair of magnetic elements may be defined as a first electromagnet 33 and a first permanent magnet 23, and are respectively disposed in the box cover 20 and the body 30 of the earphone charging box 40. The magnetism generated by the first electromagnet 33 during the power-on period is configured to generate a repulsive force with the first permanent magnet 23, and the lid 20 and the body 30 are automatically opened by the repulsive force of the magnetism.

As a preferred embodiment, for simple wiring, the first electromagnet 33 is preferably disposed within the body 30 of the earphone charging box 40 and adjacent to the top surface 35 of the body 30, and preferably centrally disposed as shown in fig. 2 and 3. Meanwhile, a cover opening key 36 is arranged on the shell of the body 30, the cover opening key is connected with a PCT board arranged in the body 30, and a control module 37 is arranged on the PCT board and used for detecting the trigger state of the cover opening key 36 and further controlling the power-on and power-off state of the first electromagnet 33 according to the trigger state.

Specifically, as shown in fig. 4, the first electromagnet 33 may be arranged to be connected to the battery 32 in the main body 30 via a power line, and a switch K1 may be connected in series to the power line. When the control module 37 detects that the door opening button 36 is triggered, a control signal is output, the control switch K1 is closed, the power-on loop of the battery 32 and the first electromagnet 33 is communicated, the first electromagnet 33 is powered on to generate magnetism, and the door opening operation is responded.

The first permanent magnet 23 is preferably disposed in the case cover 20 of the earphone charging case 40. The lid 20 can be divided into a front half 21 and a rear half 22, and the bottom 27 of the rear half 22 is connected to the body 30 by a rotational connector 25 (e.g., a hinge, etc.), so that the lid 20 and the body 30 can be rotatably assembled. The first permanent magnet 23 is arranged in the front half 21 of the lid 20, adjacent to the bottom 27, preferably centrally, so that the first permanent magnet 23 is exactly aligned with the first electromagnet 33 arranged in the body 30 in the closed state of the lid 20. When the door opening button 36 on the body 30 is pressed by a user, the first electromagnet 33 is energized to generate magnetism, the magnetic poles of the adjacent surfaces of the first electromagnet 33 and the first permanent magnet 23 are configured to be the same, and then a repulsive force F1 is generated to push the box cover 20 to open.

In order to fully open the box cover 20, in the present embodiment, a cover opening weight 24 is further disposed in the box cover 20, and as shown in fig. 1 and 2, the cover opening weight is preferably disposed at the rear half portion 22 of the box cover 20 and near the top surface 26 of the box cover 20. In the process that the box cover 20 is opened by the repulsive force F1, the cover opening counterweight 24 can generate a certain torque F in the cover opening direction by utilizing the weight of the cover opening counterweight 24, so that the box cover 20 is assisted to be fully opened, and the automatic cover opening function is realized.

After the box cover 20 is opened smoothly, the power supply of the first electromagnet 33 can be cut off to save the electric quantity of the battery 32 in the earphone charging box. For the purpose of this design, the embodiment further provides a hall sensor (not shown in the figure) on the body 30 of the earphone charging box, for sensing the magnetism of the first electromagnet 33 and generating a sensing signal to be sent to the control module 37, as shown in fig. 4. When the box cover 20 is in a closed state, the hall sensor can sense the magnetism of the first electromagnet 33; on the contrary, when the lid 20 is completely opened, the hall sensor does not sense the magnetism of the first electromagnet 33. The control module 37 judges the open/close state of the box cover 20 according to the sensing signal fed back by the hall sensor. When the control module 37 controls the first electromagnet 33 to be energized, if the hall sensor does not detect the magnetism of the first electromagnet 33, it is determined that the box cover 20 is completely opened. At this time, the control module 37 controls the switch K1 to be turned off, so as to cut off the power supply loop between the battery 32 and the first electromagnet 33, and to turn off the first electromagnet 33, thereby saving the power of the battery 32.

Of course, the arrangement positions of the first electromagnet 33 and the first permanent magnet 23 can be interchanged, that is, the first electromagnet 33 is arranged on the box cover 20, and the first permanent magnet 23 is arranged in the body 30, which can also meet the design requirement. However, this arrangement requires a lead from the body 30 to the lid 20, and the wiring design is relatively complicated.

In order to facilitate the user to take out the wireless headset 10 from the body 30 after the lid 20 is opened, in this embodiment, a pair of magnetic elements, such as the second electromagnet 14 and the second permanent magnet 34, are preferably disposed in the body 30 of the wireless headset 10 and the headset charging box, as shown in fig. 1 and 3, respectively, so that the wireless headset 10 can be automatically ejected from the headset cavity 31 of the body 30 after the lid 20 is opened.

In some embodiments, the second electromagnet 14 may be disposed in the wireless headset 10 and the second permanent magnet 34 may be disposed in the body 30 of the headset charging box.

Specifically, as shown in fig. 3, in the body 30 of the earphone charging box, two earphone pods 31 form a transition surface 36 with the top surface 35 of the body 30. When the wireless headset 10 is inserted into the headset cavity 31, the bottom surface of the in-ear portion 12 of the wireless headset 10 abuts against the transition surface 36. The second electromagnet 14 is arranged in the ear-entering part 12 of the wireless earphone 10 and is close to the bottom surface of the ear-entering part 12; the second permanent magnet 34 is disposed within the body 30 of the earphone charging box and adjacent to the transition surface 36. When the ear-entering part 12 of the wireless earphone 10 is pressed on the transition surface 36 of the body 30, the second electromagnet 14 and the second permanent magnet 34 are just in a vertically opposite position relation. The second electromagnet 14 is configured such that when energized, the second electromagnet 14 has the same magnetic polarity as the adjacent face of the second permanent magnet 34, which in turn generates a repulsive force F2 to urge the wireless headset 10 to partially eject out of the headset housing 31.

As shown in fig. 4, in order to control the on/off state of the second electromagnet 14, the wireless module is further disposed in the main body 30 of the charging box of the earphone, preferably disposed on the PCB, and connected to the control module 37. After detecting that the cover 20 of the earphone charging box is completely opened, the control module 37 generates an earphone ejection instruction, and sends the earphone ejection instruction to the wireless earphone 10 through the wireless module. The wireless earphone 10 receives the earphone ejecting instruction by using the wireless communication control unit configured in the wireless earphone 10, and then controls the rechargeable battery 13 in the wireless earphone 10 to supply power to the second electromagnet 14.

Specifically, the second electromagnet 14 may be configured to be connected to the rechargeable battery 13 in the wireless headset 10 via a power cord, and the switch K2 may be connected in series to the power cord. After receiving an earphone ejecting instruction sent by the earphone charging box 40, the wireless communication control unit controls the switch K2 to be closed, and the switch K is communicated with an electrifying loop of the second electromagnet 14, so that the second electromagnet 14 generates magnetism and is mutually exclusive with the second permanent magnet 34 in the earphone charging box 40, and the wireless earphone 10 is further pushed to eject out of the earphone bin 31, and a user can take the wireless earphone conveniently.

After the wireless earphone 10 is taken out from the earphone chamber 31, in order to control the second electromagnet 14 to be powered off in time so as to save the electric quantity of the rechargeable battery 13, in this embodiment, an optical sensor (not shown in the figure) is preferably added on the handheld portion 11 of the wireless earphone 10, so as to detect whether the handheld portion 11 is located in the earphone chamber 31, and generate a corresponding detection signal to be sent to the wireless communication control unit. Specifically, while the wireless communication control unit controls the second electromagnet 14 to be energized, if the optical sensor does not detect an optical signal, it is determined that the wireless headset 10 is not taken out, and the energized state of the second electromagnet 14 is maintained. When the optical signal is collected by the optical sensor, the wireless headset 10 is considered to be removed. At this time, the wireless communication control unit controls the switch K2 to be turned off, and cuts off the power supply from the rechargeable battery 13 to the second electromagnet 14, so as to save the power and prolong the endurance time of the wireless headset 10.

In other embodiments, the second electromagnet 14 may be disposed in the body 30 of the charging box and the second permanent magnet 34 may be disposed in the wireless headset 10.

Specifically, the second electromagnet 14 is disposed in the main body 30 of the charging box of the earphone and near the transition surface 36, and the second permanent magnet 34 is disposed in the ear insertion portion 12 of the wireless earphone 10 and near the bottom surface of the ear insertion portion 12. When the ear entrance part 12 of the wireless earphone 10 is pressed against the transition surface 36 of the earphone charging box body 30, the second electromagnet 14 and the second permanent magnet 34 are just in a vertically opposite position relation. The second electromagnet 14 is configured such that when energized, the adjacent faces of the second electromagnet 14 and the second permanent magnet 34 have the same magnetic polarity, which in turn generates a repulsive force F2 that pushes the wireless headset 10 partially out of the headset housing 31.

With this arrangement, the switch K2 and the optical sensor can be arranged on the body 30 of the earphone charging box, as shown in fig. 5. The switch K2 is connected in series in the power line connecting the battery 32 and the second electromagnet 14 and receives a control signal from the control module 37 in the body 30. An optical sensor is arranged on the inner wall of the earpiece cavity 31 for detecting the presence of the wireless earpiece 10 inside the earpiece cavity 31.

The working principle is as follows: after detecting that the box cover 20 of the earphone charging box is completely opened, the control module 37 outputs a control signal to control the switch K2 to be closed, and the power-on loop of the second electromagnet 14 is connected, so that the second electromagnet 14 and the second permanent magnet 34 disposed in the wireless earphone 10 generate a repulsive force F2, and then the wireless earphone 10 is pushed to partially eject out of the earphone chamber 31, so that the user can take out the earphone.

When the wireless headset 10 is taken out of the headset housing 31, the optical sensor collects the optical signal and outputs a detection signal to the control module 37. At this time, the control module 37 controls the switch K2 to be turned off, and cuts off the power supply from the battery 32 to the second electromagnet 14, so as to save the power of the battery 32.

This embodiment carries out institutional advancement to wireless earphone and supporting earphone charging box based on electromagnetism principle, has realized the lid of charging box and has opened and wireless earphone auto-eject's function automatically, has made things convenient for user's use, has improved the intellectuality of product.
