The electromagnetic member 50 is installed at the bottom of the case 10. The electromagnetic member 50 is composed of an iron core 61 and an electromagnetic coil 62 wound around the surface of the iron core 61. The electromagnetic member 50 can change the magnetic poles at both ends of the electromagnetic member 50 by being energized and de-energized.

Wherein, in case that the opening of the case 10 is away from the ground, the conductive rod 73 is engaged with the conductive block 72, and the electromagnetic member 50 is electrically conductive. When the opening of the case 10 faces the ground, the conductive rod 73 and the conductive block 72 are disconnected, and the electromagnetic member 50 is de-energized.

That is, as shown in fig. 1 and 2, the earphone box 100 is further provided with a power supply 71, a conductive block 72, and a conductive rod 73, wherein the power supply 71 is provided inside the box body 10, and the conductive block 72 is connected with the power supply 71.

Meanwhile, the slide cylinder 30 drives the slide cylinder 30 to slide out of the chute 11 under the gravity action of the magnetic attraction piece 40, so as to carry the earphone 80.

In the case where the opening of the case 10 is away from the ground, the case 10 is in a state of being laid right, see fig. 1, in which one conductive rod 73 supports the conductive block 72 and one end of the other conductive rod is connected to the power supply 71. The conductive block 72 is located on a conductive rod 73, the conductive rod 73 supports the conductive block 72, and the conductive block 72 is engaged with the conductive rod 73. The power source 71, the conductive block 72, the conductive rod 73 and the electromagnetic element 50 form a current path therebetween, the electromagnetic coil 62 is energized, and the electromagnetic element 50 and the magnetic element 40 are attracted by the iron core 61 under the current action of the electromagnetic coil 60, so as to ensure that the slide cylinder 30 and the magnetic element 40 can be firmly and stably fixed at the bottom of the earphone box 100.

According to an embodiment of the present invention, the sliding grooves 11 are arc-shaped grooves, each sliding groove 11 extends from the upper end of the box 10 toward the bottom of the box 10, and the two sliding grooves 11 are symmetrically distributed. The cross-sectional shape of the slide cylinder 30 corresponds to the cross-sectional shape of the slide groove 11, and the cross-sectional arc length of the slide cylinder 30 is equal to the cross-sectional arc length of the slide groove 11.

That is, as shown in fig. 1 and 2, the sliding grooves 11 in the box 10 may be processed into arc-shaped grooves, each sliding groove 11 may extend from the upper end of the box 10 toward the bottom of the box 10, respectively, and the two sliding grooves 11 are symmetrically distributed. By providing the slide groove 11 as an arc-shaped groove, the slide cylinder 30 is facilitated to move relative to the slide groove 11. When the box body 10 is in an inverted state, the speed of the slide cylinder 30 sliding out of the slide groove 11 is improved, and the slide cylinder 30 can timely receive the two earphones 80. The cross section of the slide cylinder 30 corresponds to the cross section of the sliding groove 11, and the arc length of the cross section of the slide cylinder 30 is equal to that of the sliding groove 11, so that the earphone 80 can be smoothly received when the slide cylinder 30 slides out. Of course, in the present application, the specific shape of the sliding slot 11 and the specific size of the sliding barrel 30 can be set according to actual requirements, and the design scheme that the sliding barrel 30 can carry the earphone 80 when the sliding barrel 30 is switched between the normal state and the leading state is all within the protection scope of the present application.

In the present application, as shown in fig. 2, when the earphone 80 is placed in the earphone box 100, the inverted false open mode occurs, that is, the earphone box 100 is in an inverted state. At this time, the conductive piece 72 is separated from the conductive rod 73 by gravity, and the current path is broken. The electromagnetic member 50 loses its magnetism due to the power failure. The two magnetic elements 40 are disengaged from the electromagnetic element 50 and each magnetic element 40 moves down to the first end of the slide 30. Then, the magnetic attraction pieces 40 are driven by the gravity (the gravity of the magnetic attraction pieces 40 is far greater than that of the slide cylinder 30), so as to drive the slide cylinder 30 to move downwards. And because the two magnetic suction pieces 40 act on the lower part of the earphone body due to the attraction acting force and the self gravity, the two sliding cylinders 30 just drag the earphone 80, and the falling-off prevention effect is achieved.

In summary, according to the earphone box 100 of the embodiment of the present invention, the slide groove 11 is disposed in the box body 10, the slide cylinder 30 is disposed in the slide groove 11, and the electromagnetic force action between the electromagnet 50 and the magnetic attraction member 40 is utilized. When the box 10 is in the inverted state, the electromagnetic element 50 is powered off, the magnetism of the electromagnetic element 50 disappears, and the electromagnetic element 50 and the magnetic element 40 are separated from each other. Under the action of the magnetic attraction piece 40, the sliding cylinder 30 drives a part of the sliding cylinder 30 to slide out of the sliding slot 11 by the magnetic attraction piece 40. And under the condition that the box body 10 is plugged with the earphones 80, the part of the slide cylinder 30, which slides out of the slide groove 11, is used for bearing the earphones 80, so that the slide cylinder 30 can be used for dragging the earphones 80, and the earphones 80 are prevented from falling off from the box body 10. This application bears earphone 80 through slide cartridge 30, can guarantee that earphone box 100 can also prevent effectively that earphone 80 from droing under the violent condition of shake, more effectual protection earphone 80, extension earphone 80 life.
