It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

For convenience of understanding and explanation, the earphone ejection device provided by the embodiment of the present application is explained in detail by fig. 1 to 5.

Please refer to fig. 1, which is a schematic structural diagram of an earphone ejection device according to an embodiment of the present application. The earphone ejection device 10 comprises a cavity 101 for accommodating the earphone 11, a first hall element 102 and an electromagnetic coil 103 which are arranged at the bottom of the cavity 101, and a controller which is respectively connected with the first hall element 102 and the electromagnetic coil 103.

Wherein the first hall element 102 is used for sensing whether the earphone 11 is in the cavity 101, the electromagnetic coil 103 is used for generating magnetism with the same polarity as the magnetic element 111 in the energized state, and the controller is used for controlling the electromagnetic coil 103 to be powered on and powered off according to the instruction sent by the first hall element 102, for example, the electromagnetic coil 103 can include but is not limited to an iron core coil. Illustratively, as shown in fig. 2, the rear portion of the earphone 11 is provided with a magnetic element 111, the magnetic element 111 is glued between a circuit board and a tail plug 112 in the earphone 11, so when the first hall element 102 senses that the earphone 11 is in the cavity 101, the first hall element 102 sends a command for controlling the energization of the electromagnetic coil 103 to the controller, and the electromagnetic coil 103 can generate magnetism with the same polarity as the magnetic element 111 at the rear portion of the earphone 11, so that the earphone 11 can be automatically ejected against its own weight under the action of the repulsive force between the electromagnetic coil 103 and the magnetic element 111.

Optionally, some embodiments of the present application further provide a charging assembly 104 at the bottom of the cavity 101 for charging the earphone 11. Correspondingly, a copper post 113 is provided in the tail plug 112 of the earphone 11 and is connectable to the charging unit 104. Illustratively, the charging assembly 104 may include a needle, a needle cannula secured to the bottom of the housing 101, and a spring disposed within the needle cannula. Wherein, one end of the spring is connected with the needle tube, and the other end is connected with the needle head. The advantage of this arrangement is that the duration of the earphone 11 can be increased, and the volume of the earphone ejecting device 10 can be reduced, so as to save space and facilitate carrying.

Optionally, in some embodiments of the present application, the earphone ejecting apparatus 10 further includes a distance sensor 105 connected to the controller, and the distance sensor 105 is configured to detect a lifting height of the earphone 11 and send the lifting height to the controller, so that the controller can adjust the current intensity of the electromagnetic coil 103 according to the lifting height. The advantage of setting up like this is because earphone 11 is by the lifting in-process, and the effort between the magnet can present nonlinear variation along with the increase of lifting height, therefore the controller of the embodiment of this application is through the current strength who adjusts solenoid 103, and then changes the trend of change of repulsion force between solenoid 103 and earphone 11 afterbody magnetic element 111, can make earphone 11 can be popped out smoothly, avoids lifting uncontrollable, the risk that earphone 11 is popped off even appears.

Further, for example, when the sound outlet 114 of the earphone 11 is completely exposed out of the lower cover of the earphone ejection device 10, the lifting height of the earphone 11 is 12mm, and the controller adjusts the current in the electromagnetic coil 103 to be a constant current so as to output an electromagnetic repulsion force balanced with the gravity and the electromagnetic attraction force of the earphone, so that the earphone 11 can be suspended smoothly. When the user takes the earphone 11 away, the lifting height of the earphone 11 is greater than a preset threshold value, for example, the preset threshold value is 12mm, so that the electromagnetic coil 103 is powered off. Optionally, for the in-ear earphone, the outer surface of the sound outlet nozzle 114 may be further provided with a rubber plug, so that impurities can be prevented from entering the sound outlet nozzle 114, and the sound quality of the earphone can be further affected.

Optionally, the distance sensor 105 may be disposed on the cavity 101 at a position corresponding to a position below the rear portion of the earphone 11 in some embodiments of the present disclosure. Alternatively, as shown in fig. 1, the distance sensor 105 may be disposed on the cavity 101 at a position corresponding to the position below the sound outlet 114 of the head of the earphone 11, which has the advantages that the measured lifting height is more accurate and reliable because the weight of the head of the earphone is greater than that of the rod of the earphone.

Optionally, in some embodiments of the present invention, a first fixed magnet 1011 is disposed on a side surface of the earphone 11, and a second fixed magnet 1012 is disposed on an inner wall of the cavity 101 at a position corresponding to the first fixed magnet 1011. The first fixed magnet 1011 and the second fixed magnet 1012 have opposite polarities, so that the two fixed magnets can attract each other to fix the earphone 11, so that the earphone 11 does not shake in the earphone slot and is in good contact with the charging assembly 104. For example, as shown in fig. 3, since the weight of the headset head is greater than that of the headset rod, the first fixing magnet 1011 is disposed on the head of the headset 11 and the second fixing magnet 1012 is disposed on the upper end of the inner wall of the cavity 101 in the embodiment of the present application, so that the headset 11 can be intensively stressed and fixed more firmly.

Based on the foregoing embodiments, the present application provides an overall structure schematic diagram of a headphone pop-up device. Referring to fig. 4, the earphone ejection device 10 includes a cavity 101 and a cover 106 connected to the cavity 101, wherein the cavity 101 may include two earphone slots, i.e., a left earphone slot 1013 and a right earphone slot 1014.

Optionally, in the embodiment of the present application, an induction magnet is disposed on the cover 106. As shown in fig. 5, a second hall element 107 is disposed above the chamber 101 at a position corresponding to the sensing magnet, and the second hall element 107 is used for sensing the open/close state of the cover 106.

In the actual use process, when the user opens the cover 106, the second hall element 107 connected to the main board senses the change of the magnetic flux, and the first hall element 102 connected to the sub board detects that the earphone 11 is in the cavity 101, and then the first hall element 102 sends a power-on command to the controller, so that the electromagnetic coil 103 glued to the bottom of the cavity 101 can generate magnetism with the same polarity as the magnetic element 111 at the tail of the earphone 11. Under the action of the repulsive force between the electromagnetic coil 103 and the magnetic element 111, the earphone 11 can be automatically ejected against the self-gravity. Optionally, in some embodiments of the present application, the first hall element 102 may also send a matching instruction to the controller at the same time, so that the earphone 11 can be automatically matched with the previously connected electronic device, thereby improving the connection efficiency. In addition, when the headset 11 and the electronic device are connected for the first time, the user is required to manually connect.

Further, as the lifting height of the earphone 11 increases, the controller continuously adjusts the current intensity of the electromagnetic coil 103 according to the lifting height, so that the earphone 11 can be suspended stably. When the user takes the earphone 11 away, the lifting height of the earphone 11 is greater than the preset threshold value 12mm, and therefore the electromagnetic coil 103 is powered off.

Further, when the user needs to put the earphone 11 back into the cavity 101, the user opens the cover 106, the second hall element 107 senses that the magnetic flux changes, but the first hall element 102 detects that the earphone 11 is not in the cavity 101, and then the first hall element 102 sends a power-off instruction to the controller, so that the electromagnetic coil 103 is not powered on, and therefore the user can easily put the earphone 11 into the cavity 101.

Alternatively, in some embodiments of the present application, when the user opens the cover 106 but the earphone 11 is not removed, the electromagnetic coil 103 is always in the energized state. To save power, the user can turn off the power to the electromagnetic coil 103 through the button 108 disposed on the outer wall of the cavity 101, and then the earphone 11 can automatically fall back to the corresponding earphone slot.

It should be noted that, for the descriptions of the same contents in this embodiment as in the other embodiments, reference may be made to the descriptions in the other embodiments, and details are not described here again.

The earphone popping device provided by the embodiment of the application comprises a cavity for accommodating the earphone, a first Hall element and an electromagnetic coil which are arranged at the bottom of the cavity, and a controller respectively connected with the first Hall element and the electromagnetic coil. In the in-service use process, when first hall element sensed the earphone in the cavity, this first hall element sent the instruction that control solenoid circular telegram to the controller, and then solenoid can produce the magnetism the same with earphone afterbody magnetic element polarity, consequently under the effect of repulsion between solenoid and magnetic element, the earphone can overcome self gravity and auto-eject, has improved the availability factor.
