Detailed Description
Unless defined otherwise, technical or scientific terms used in the specification and claims should be given the ordinary meaning as understood by one of ordinary skill in the art to which the invention pertains. In the following, specific embodiments of the present invention will be described with reference to the drawings, and it should be noted that in the course of the detailed description of these embodiments, it is not possible in the present specification to describe all features of an actual embodiment in detail for the sake of brevity.

In order to prevent the earphone from shaking at will in the charging bin, the earphone is fixed by the attraction of the magnet after being placed in the charging bin, and meanwhile, the shape in the charging bin is basically equal to the shape of the earphone. The earphone is arranged in and can be restrained by magnetic force all the time when taking out after charging the storehouse, and appearance design is taken out laboriously in addition, especially when earphone body designs into smooth surface or user's hand has greasy dirt water stain, takes out more difficultly.

As shown in fig. 4, the second conductive elastic element 107 and the fourth conductive elastic element 110 are connected to the positive electrode of the battery.
The structure of the charging bin provided by the application is introduced. The working principle of the charging bin is described below.
First, the charging characteristics of the wireless earphone will be described.
As shown in fig. 5, when the battery voltage inside the wireless earphone is under-voltage protected, the wireless earphone enters a trickle-charge mode (trickle-charge mode) after being connected to an external charging device, and trickle charging is started, so that the trickle charging current is low. The Battery Voltage (Battery Voltage) during trickle charging will slowly rise with charging of the charging Current (Charge Current). When the battery voltage detection module detects that the battery voltage has reached a first voltage set point (e.g., 2V), it shifts to a pre-charge mode. And after the battery voltage continues to rise to the second voltage set value, the battery enters a fast charging mode, the fast charging mode is a constant current charging mode, the charging current is maximum, and the battery voltage is slowly raised. When the battery voltage rises to the third voltage set value in the constant voltage charging mode, the constant voltage charging is changed, that is, the battery voltage is unchanged, and the charging current is gradually reduced. And when the charging current is reduced to the cut-off current set by the software, stopping charging, wherein the charging current is 0mA, and the charging is completed. If the external charging device is not disconnected, when the battery voltage in the wireless earphone drops to the fourth voltage set value, a new charging is started.
The relationship between the magnetic field generated by the electromagnet 103 and the charging current is that the larger the charging current is, the stronger the magnetic field intensity formed by the energizing coil is, the smaller the reverse charging current is, the weaker the magnetic field intensity is, and the larger the number of turns of the energizing coil is, the stronger the magnetic field intensity formed by the energizing coil is, the smaller the reverse number is, and the weaker the magnetic field intensity is. The magnetic field direction satisfies the left hand spiral law.
The charging of the first wireless headset is exemplified below.
When the battery of the first wireless earphone is not powered, the first wireless earphone is placed in the first accommodating cavity 1051 of the charging bin, the first conductive elastic element 102 on the bottom of the charging bin is contacted with the first charging interface C1 of the first wireless earphone, the second conductive elastic element 107 is contacted with the second charging interface C2 of the first wireless earphone, a charging mode is started, when charging current flows through the electromagnet 103 composed of a coil and ferrite, the electromagnet 103 can generate a magnetic field, because of direct current charging, the magnetic pole of the electromagnet 103 can be controlled by controlling the winding direction of the coil. The electromagnet 103 and the permanent magnet on the sound cavity of the first wireless earphone are attracted mutually, and the electromagnet 103 is fixed in the charging bin, so that the magnetic force attracts the first wireless earphone to ensure the charging process.
And stopping charging when the first wireless earphone is charged to reach the set cut-off current, wherein the charging current is zero. The magnetic force of the electromagnet 103 disappears, and the first conductive elastic element 102 and the second conductive elastic element 107 at the bottom of the charging bin slightly jack up the first wireless earphone because of no electromagnetic force constraint, so that a user can conveniently take the first wireless earphone.
Meanwhile, if the battery voltage of the first wireless earphone drops due to long-time non-use, the charging bin charges the first wireless earphone again (the first conductive elastic element 102 is in contact with the first wireless earphone, and the whole charging circuit is not broken). The first wireless earphone is sucked into the charging bin due to electromagnetic force.
When the first wireless earphone is in a charging state in the charging bin, the first wireless earphone is sucked by the suction force of the electromagnet 103, at the moment, if a user wants to take out the first wireless earphone, the key 101 can be pressed, the charging loop is cut off, so that the electromagnet 103 loses magnetism and does not suck the first wireless earphone, the first conductive elastic element 102 at the bottom of the charging bin slightly pushes up the first wireless earphone, and therefore the user can conveniently and still easily take the first wireless earphone when the first wireless earphone is charged, and the influence of the battery charging state of the first wireless earphone is avoided.
When the user does not press the key 101 any more, the two ends of the bottom D of the touch switch 104 are restored to be connected with the first wire 108, and when the first wireless earphone is placed in the charging bin, the charging state is again entered.
In this embodiment, when the wireless earphone is charging, the first conductive elastic element jacks up the wireless earphone, so that the user can easily take out the wireless earphone from the charging bin. Therefore, the technical scheme provided by the application can be convenient for a user to take the wireless earphone out of the charging bin. Moreover, when the wireless earphone is being charged, the wireless earphone is jacked up by the first conductive elastic element, so that the wireless earphone is completely charged, and a user can clearly know that the wireless earphone is completely charged when seeing that the wireless earphone is jacked up. The charging state of the battery of the wireless earphone is prompted to the user through the form of the wireless earphone in the charging bin, and the problem that the user misunderstands to be drift because the user cannot know the charging state of the battery of the wireless earphone is avoided.
In this embodiment, the change of the charging current and the relationship between the magnetic field and the charging current are used to convert the charging current into a force to control whether the wireless earphone is sucked or not.
The application further provides a charging bin. In the above embodiment, the touch switch 104 is connected between the first conductive elastic element 102 and the first pole of the battery, and in the present embodiment, the touch switch 104 is connected between the second conductive elastic element 107 and the second pole of the battery.
In this embodiment, the charging bin may include a bin body 100, a housing 105, a first conductive elastic element 102, a second conductive elastic element 107, an electromagnet 103, a battery, a touch switch 104, a key 101, and a second conductive wire, where an opening is provided on the bin body 100.
