[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Please refer to Figures 1 to 5The present invention provides a charging box body 10, which is used in conjunction with a wireless headset 20. The wireless headset 20 includes an earphone body 21 and an earphone side magnetic member 22 connected to the earphone body 21. The wireless headset 20 has an installation cavity 201. The earphone side magnetic member 22 is installed on the cavity wall of the installation cavity 201. The earphone side magnetic member 22 has a first magnetic pole and a second magnetic pole with opposite magnetic properties and arranged in sequence along an operating direction. The operating direction in this embodiment is from bottom to top.

[0029] Please refer to Figures 1 to 3 , wherein the charging box body 10 includes a bottom shell 11, an upper cover 12, a box body power supply 17, a unipolar Hall switch 14, a box body side magnetic part 13 and an indicator light 16, the box body power supply 17, the unipolar Hall switch 14 and the box body side magnetic part 13 are all connected to the bottom shell 11, the box body side magnetic part 13 and the earphone side magnetic part 22 are arranged in sequence in the working direction, the box body side magnetic part 13 has a first magnetic pole and a second magnetic pole with opposite magnetic properties and arranged in sequence along the working direction, the first magnetic pole of the earphone side magnetic part 22 can be magnetically attracted to the second magnetic pole of the box body side magnetic part 13, and the upper cover 12 is rotatably connected to the bottom shell 11 and can cover the bottom shell 11. The box body power supply 17 has an on state in which power can be supplied and a off state in which power is disconnected. The unipolar Hall switch 14 is electrically connected to the box power supply 17 and is used to switch the box power supply 17 between an on state and an off state. The unipolar Hall switch 14 is used to sense the first magnetic pole of the earphone side magnetic member 22 and to turn the box power supply 17 on when sensing its first magnetic pole. The box power supply 17 charges the earphone body 21 when it is on. The unipolar Hall switch 14 can also be used to sense the first magnetic pole of the box side magnetic member 13. The first magnetic pole of the box side magnetic member 13 has a magnetic field coverage area that can be covered by its magnetic field, that is, the unipolar Hall switch 14 can sense the first magnetic pole of the box side magnetic member 13 when it is located in the magnetic field coverage area. The unipolar Hall switch 14 is set to avoid the magnetic field radiation area, that is, the unipolar Hall switch 14 is set at a position where the box side magnetic member 13 cannot be sensed, so as not to affect the switching operation of the unipolar Hall switch 14 on the box power supply 17.

[0030] The charging box 10 of the present invention enables the earphone body 21 to be accurately aligned and fixed in position by magnetically attracting the second magnetic pole of the box side magnetic part 13 to the first magnetic pole of the earphone side magnetic part 22, so as to realize the charging connection of the box power supply 17 to the wireless earphone 20, and prevent poor contact due to shaking of the wireless earphone 20. The charging box 10 of the present invention also sets the unipolar Hall switch 14 at a position where the box side magnetic part 13 cannot be sensed, so that the installation of the box side magnetic part 13 does not affect the control of the box power supply 17 by the unipolar Hall switch 14. When the wireless earphone 20 is close to the charging box 10, the unipolar Hall switch 14 can only sense the first magnetic pole of the earphone side magnetic part 22, and when the first magnetic pole is sensed, the box power supply 17 is switched from the closed state to the open state. When the box side magnetic part 13 and the earphone side magnetic part 22 are magnetically attracted and in the open state, the box power supply 17 can charge the earphone body 21. In this way, the charging box 10 can realize automatic alignment of the wireless headset 20 through the magnetic part 13 on the side of the box, and the unipolar Hall switch 14 can start the box power supply 17 only by approaching the wireless headset 20, without the need to cover the upper cover 12, thereby ensuring the smooth progress of the charging process.

[0031] The box body side magnetic part 13 and the earphone side magnetic part 22 can be permanent magnets or electromagnets, respectively. That is, the first magnetic pole and the second magnetic pole of the box body side magnetic part 13 and the earphone side magnetic part 22 are both two magnetic poles of a magnet, that is, the two are N poles and S poles, respectively, wherein, when the first magnetic pole is N pole and the second magnetic pole is S pole; when the first magnetic pole is S pole and the second magnetic pole is N pole. The unipolar Hall switch 14 can only sense one polarity. In this embodiment, it can sense the first magnetic pole. The following embodiments take the first magnetic pole as N pole as an example. When the unipolar Hall switch 14 senses the N pole, it can switch the box body power supply 17 from the off state to the on state, ready to supply power. When the unipolar Hall switch 14 cannot sense the N pole, it can switch the box body power supply 17 from the on state to the off state to avoid leakage. The magnetic part 13 on the box body side also has an N pole, and this N pole has a magnetic field coverage area. When the unipolar Hall switch 14 is located in this magnetic field coverage area, it can sense the N pole of the magnetic part 13 on the box body side. In order to prevent this N pole from affecting the operation of the unipolar Hall switch 14, the unipolar Hall switch 14 is set to avoid the magnetic field coverage area, that is, it is set at a position where the N pole of the magnetic part 13 on the box body side cannot be sensed.

[0032] Please refer to Figures 1 to 3The bottom shell 11 has a shell cavity 101, the box body power supply 17, the unipolar Hall switch 14, the box body side magnetic part 13 and the indicator light 16 are all located in the shell cavity 101, the surface of the bottom shell 11 has a placement position for placing the wireless headset 20, and the placement position can be on a plane. Preferably, the bottom shell 11 is provided with a receiving groove 102 adapted to the wireless headset 20, and the upper cover 12 can cover the receiving groove 102, and the placement position is located in the receiving groove 102. The receiving groove 102 is used to limit the position of the wireless headset 20 and play a role in positioning the wireless headset 20. The upper cover 12 is used to protect the wireless headset 20 placed in the receiving groove 102 to prevent the wireless headset 20 from falling out or falling dust.

[0033] The bottom shell is provided with two receiving grooves 102, which are arranged along the left-right direction. One receiving groove 102 is used to adapt a wireless headset 20. Preferably, the two receiving grooves 102 are symmetrically arranged so as to place two symmetrical wireless headsets 20 suitable for the left and right ears respectively.

[0034] In one embodiment, the box body side magnetic part 13 and the unipolar Hall switch 14 may both be provided with one and located in the shell cavity 101 between the two accommodating grooves 102. At this time, the S pole of the box body side magnetic part 13 can be attracted to the N pole of the earphone side magnetic part 22 of the two wireless headphones 20. The unipolar Hall switch 14 can start the box body power supply 17 when it senses the N pole of any earphone side magnetic part 22, and switch the box body power supply 17 to the off state when the two wireless headphones 20 are away from the box body side magnetic part 13.

[0035] In another embodiment, a magnetic part 13 on the box body side is provided and is located in the shell cavity 101 between the two accommodating grooves 102, and the line connecting the N pole and the S pole of the magnetic part 13 on the box body side extends in the left and right directions. A unipolar Hall switch 14 is provided and is located on the side facing the S pole of the magnetic part 13 on the box body side. Taking the case where the N pole of the magnetic part 13 on the box body side faces left and the S pole faces right as an example, the unipolar Hall switch 14 is located between the magnetic part 13 on the box body side and the right accommodating groove 102. The wireless headset 20 in the left accommodating groove 102 is arranged so that the S pole of its earphone side magnetic part 22 faces the magnetic part 13 on the box body side, and the wireless headset 20 in the right accommodating groove 102 is arranged so that the N pole of the earphone side magnetic part 22 faces the magnetic part 13 on the box body side. At this time, the N pole and S pole of the box body side magnetic member 13 are attracted to the S pole and N pole of the two earphone side magnetic members 22 respectively, and the unipolar Hall switch 14 is used to sense the N pole of the earphone side magnetic member 22 in the right receiving groove 102. The unipolar Hall switch 14 starts the box body power supply 17 when sensing the N pole of the right earphone side magnetic member 22, and switches the box body power supply 17 to the off state when the right wireless earphone 20 is away from the box body side magnetic member 13. The placement and removal of the wireless earphone 20 in the left receiving groove 102 does not affect the control of the box body power supply 17 by the unipolar Hall switch 14.

[0036] In another embodiment, two magnetic parts 13 are provided on the box body side, one box body side magnetic part 13 corresponds to one wireless headset 20, and one unipolar Hall switch 14 is provided, which is located in the shell cavity 101 between the two accommodating grooves 102. At this time, the S poles of the two box body side magnetic parts 13 are both facing the wireless headset 20, and can be attracted with the N poles of the earphone side magnetic parts 22 of the two wireless headsets 20. The unipolar Hall switch 14 can start the box body power supply 17 when it senses the N pole of any earphone side magnetic part 22, and switch the box body power supply 17 to the off state when the two wireless headsets 20 are away from the box body side magnetic part 13.

[0037] In this embodiment, two magnetic parts 13 are provided on the box body side, and one magnetic part 13 on the box body side corresponds to one wireless headset 20. Two unipolar Hall switches 14 are provided and are respectively located between the magnetic part 13 on the box body side and the magnetic part 22 on the headset side. At this time, the S poles of the two magnetic parts 13 on the box body side are facing the wireless headset 20, and can be attracted to the N poles of the earphone side magnetic parts 22 of the two wireless headsets 20. Any unipolar Hall switch 14 can start the box body power supply 17 when it senses the N pole of the corresponding earphone side magnetic part 22, and the box body power supply 17 can be switched to the off state only when the two wireless headsets 20 are away from the magnetic part 13 on the box body side.

[0038] In other embodiments, two magnetic parts 13 are provided on the box body side, and one magnetic part 13 on the box body side corresponds to one wireless headset 20. Two unipolar Hall switches 14 are provided and are respectively located between the magnetic part 13 on the box body side and the magnetic part 22 on the headset side. The two magnetic parts 13 on the box body side can respectively face the S pole and the N pole toward the wireless headset 20. The two unipolar Hall switches 14 can respectively sense the N pole and the S pole. If the magnetic part 13 on the box body side corresponding to the left side accommodating groove 102 faces the wireless headset 20 with the S pole, the unipolar Hall switch 14 that can sense the N pole will correspond to it, and the wireless headset 20 with the earphone side magnetic part 22 with the N pole facing the magnetic part 13 on the box body side will be placed in the left side accommodating groove 102. If the magnetic part 13 on the box body side corresponding to the right side accommodating groove 102 faces the wireless headset 20 with the N pole facing the wireless headset 20, the unipolar Hall switch 14 that can sense the S pole will correspond to it, and the wireless headset 20 with the earphone side magnetic part 22 with the S pole facing the magnetic part 13 on the box body side will be placed in the right side accommodating groove 102. The S pole of the magnetic part 13 on the left side of the box body is attracted to the N pole of the magnetic part 22 on the left side of the earphone, and the unipolar Hall switch 14 on the left side starts the box body power supply 17 when sensing the N pole of the magnetic part 22 on the left side of the earphone. The N pole of the magnetic part 13 on the right side of the box body is attracted to the S pole of the magnetic part 22 on the right side of the earphone, and the unipolar Hall switch 14 on the right side starts the box body power supply 17 when sensing the S pole of the magnetic part 22 on the right side of the earphone. The box body power supply 17 can be switched to the off state only when both wireless earphones 20 are away from the magnetic part 13 on the box body.

[0039] Please refer to Figure 5 , the N pole of the earphone side magnetic member 22 faces outward and the S pole faces the inside of the mounting cavity 201, please refer to Figure 3 , the N pole of the magnetic part 13 on the box body side faces the inner cavity 101 of the shell, and its S pole faces outward, that is, toward the accommodating groove 102, and the unipolar Hall switch 14 is located on the S pole side of the magnetic part 13 on the box body side, that is, the space facing the S pole with the plane where the magnetic part 13 on the box body side is located as the interface. When the wireless headset 20 is in the placement position, the N pole of the earphone side magnetic part 22 faces the S pole of the magnetic part 13 on the box body side and can be magnetically attracted to the S pole of the magnetic part 13 on the box body side. The earphone side magnetic part 22 is located within the sensing range of the unipolar Hall switch 14. The unipolar Hall switch 14 is used to sense the N pole of the earphone side magnetic part 22. When the S pole of the magnetic part 13 on the box body side is magnetically attracted to the N pole of the earphone side magnetic part 22, the unipolar Hall switch 14 can switch the box body power supply 17 from the off state to the on state by sensing the N pole of the earphone side magnetic part 22. At this time, the box body power supply 17 can charge the earphone body 21. The charging connection between the box power supply 17 and the earphone body 21 can be realized by wireless connection or contact electrical connection. The unipolar Hall switch 14 is preferably located between the box side magnetic member 13 and the earphone side magnetic member 22.

[0040] Please refer to Figure 2 and Figure 3 In this embodiment, the charging box body 10 also includes a contact pin 15 connected to the bottom shell 11 and electrically connected to the box body power supply 17, please refer to Figure 3 The contact pin 15 extends to the outside of the bottom shell 11. Preferably, the contact pin 15 extends upward. When the S pole of the box side magnetic member 13 and the N pole of the earphone side magnetic member 22 are magnetically attracted, the contact pin 15 can contact the earphone body 21 and be electrically connected with the earphone body 21, so that the box body power supply 17 can charge the earphone body 21. The arrangement of the contact pin 15 and the electrical contact sheet 213 realizes the direct docking of the charging box 10 and the wireless earphone 20.

[0041] Preferably, the contact pin 15 includes a probe that is arranged on the groove wall of the accommodating groove 102 and extends outward, and an elastic member connected to the probe and connected to the bottom shell 11. The wireless earphone 20 can contact the probe and cause the elastic member to deform elastically when the box body side magnetic member 13 and the earphone side magnetic member 22 are magnetically attracted. Under the action of the elastic member, the probe can be tightly contacted with the wireless earphone 20 within a certain elastic range, preventing poor contact caused by slight shaking of the wireless earphone 20, thereby improving connection reliability.

[0042] Please refer to Figure 2The charging box body 10 also includes an upper magnetic component 18 provided on the upper cover 12 and a lower magnetic component 19 provided on the bottom shell 11. The S pole of the upper magnetic component 18 faces the bottom shell 11 when the upper cover 12 is covered on the accommodating groove 102 to prevent the upper magnetic component 18 from affecting the unipolar Hall switch 14. When the upper cover 12 is covered on the accommodating groove 102, the upper magnetic component 18 can be magnetically attracted to the lower magnetic component 19, so that the upper cover 12 and the bottom shell 11 can achieve automatic closure and automatic alignment during the closing process, preventing the upper cover 12 from shaking or opening without the action of external force, and preventing the wireless headset 20 from falling off.

[0043] The lower magnetic component 19 can be a magnet with magnetic properties. The unipolar Hall switch 14 is arranged at a position where the lower magnetic component 19 cannot be sensed. The upper magnetic component 18 and the lower magnetic component 19 both have an N pole and an S pole. The N pole of the lower magnetic component 19 can be oriented toward the S pole of the upper magnetic component 18 and magnetically attracted to the S pole of the upper magnetic component 18 when the upper cover 12 is covered on the accommodating groove 102, and the S pole of the lower magnetic component 19 is oriented toward the unipolar Hall switch 14 to prevent the unipolar Hall switch 14 from being affected by the N pole of the fourth magnetic component.

[0044] The lower magnetic member 19 is an iron block, which can be magnetically attracted to the upper magnetic member 18 when the upper cover 12 is covered on the receiving groove 102 without affecting the normal operation of the unipolar Hall switch 14 . The installation range and position are not affected by the unipolar Hall switch 14 .

[0045] Please refer to Figure 1 and Figure 2 The indicator light 16 is electrically connected to the unipolar Hall switch 14, and the indicator light 16 can be activated when the box power supply 17 and the headset body 21 are connected to each other for charging. When the wireless headset 20 is placed in the receiving slot 102 and the charging connection is successful, the indicator light 16 lights up, and the user can know the charging connection status by observing whether the indicator light 16 is on, thereby realizing the visibility of the charging connection and improving the charging reliability.

[0046] Please refer to Figures 1 to 5 The embodiment of the present invention also provides an earphone charging system, including the charging box body 10 mentioned in the above embodiment. The charging box body 10 has the same structure and the same function as the charging box body 10 in the above embodiment, which will not be described here. Figure 4 and Figure 5 The earphone charging system also includes a wireless earphone 20, which includes an earphone body 21 and an earphone side magnetic member 22 connected to the earphone body 21. When the earphone body 21 is placed in the receiving groove 102, the first magnetic pole of the earphone side magnetic member is used to magnetically attract the second magnetic pole of the box body side magnetic member. At this time, the earphone body 21 and the contact pin 15 are in conflict and electrically connected. The magnetic attraction between the earphone side magnetic member 22 and the box body side magnetic member 13 realizes the automatic alignment of the earphone body 21 to avoid poor contact.

[0047] Please refer to Figure 5 The earphone body 21 includes an earphone box body 211, an earphone battery 212, an electrical contact piece 213 and a loudspeaker magnetic component 214. The earphone box body 211 has an installation cavity 201. The electrical contact piece 213, the earphone side magnetic component 22 and the loudspeaker magnetic component 214 are all located in the installation cavity 201 and connected to the earphone box body 211. The loudspeaker magnetic component 214 is used for sound emission. The earphone box body 211 is provided with a sound outlet 202 connected to the installation cavity 201, so that the sound emitted by the loudspeaker magnetic component 214 can be emitted from the sound outlet 202. The electrical contact piece 213 extends to the outside of the earphone box body 211 and is used to contact with the contact pin 15 to achieve electrical connection between the box body power supply 17 and the earphone battery 212. The electrical contact piece 213 extends downward when the wireless earphone 20 is in the placement position.

[0048] The speaker magnetic element 214 is a permanent magnet. Please refer to the figure. The N pole of the speaker magnetic element 214 faces the S pole of the earphone side magnetic element 22. This can prevent the magnetic repulsion of the earphone side magnetic element 22 from the speaker magnetic element 214 and affect the sound of the speaker magnetic element 214.

[0049] In this embodiment, the headset charging system includes two wireless headsets 20 . The two wireless headsets 20 are symmetrically arranged to accommodate the use of the left and right ears of the human body. When charging, the two wireless headsets 20 are placed in the two receiving grooves 102 respectively.

[0050] The present invention arranges a box body side magnetic part 13 on the bottom shell 11 and an earphone side magnetic part 22 on the earphone box body 211, so that when the wireless earphone 20 is placed in the placement position, it can be accurately aligned and fixed in position through the magnetic attraction between the box body side magnetic part 13 and the earphone side magnetic part 22. The unipolar Hall switch 14 can only sense the magnetism of the N pole. Therefore, when the unipolar Hall switch 14 is located on the S pole side of the box body side magnetic part 13, its N pole cannot be sensed, and the box body power supply 17 cannot be started. The N pole of the earphone side magnetic part 22 faces outward. When the wireless earphone 20 is placed in the placement position and the N pole of the earphone side magnetic part 22 is magnetically attracted to the S pole of the box body side magnetic part 13, the unipolar Hall switch 14 can sense the N pole of the earphone side magnetic part 22. At this time, the unipolar Hall switch 14 switches the box body power supply 17 from the off state to the on state. When the box body power supply 17 is in the on state, it can charge the earphone main body 21. The present invention arranges the unipolar Hall switch 14 and the box body side magnetic part 13 in such a way that the unipolar Hall switch 14 is located on the S pole side of the box body side magnetic part 13, so that the installation of the box body side magnetic part 13 does not affect the control of the box body power supply 17 by the unipolar Hall switch 14, and by making the N pole of the earphone side magnetic part 22 face outward, when the wireless earphone 20 is placed in the placement position, the box body side magnetic part 13 can be magnetically attracted to the earphone side magnetic part 22 to achieve alignment and fixation, thereby preventing the wireless earphone 20 from shaking, and the unipolar Hall switch 14 can start the box body power supply 17, thereby charging the wireless earphone 20, so that the bottom shell 11 can control the unipolar Hall switch 14 without being covered by the upper cover 12, thereby ensuring the smooth progress of the charging process.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
