As shown in fig. 1 to 12, the present embodiment provides an earphone box 100 including:

a main casing 1 having an earphone placement groove 13 capable of accommodating the earphone 200;

An ejector mechanism 2 provided in the main casing 1 and having an ejection position state and a storage position state; in the storage position state, the earphone 200 may be completely stored in the earphone storing slot 13; in the ejection position state, the ejector mechanism 2 can eject the earphone 200 out of the earphone placement groove 13; the push-out mechanism 2 is pushed by the pushed earphone 200, so that the push-out position state and the storage position state can be switched.

Specifically, when accomodating, earphone 200 is placed in earphone standing groove 13 entirely, avoids the problem that earphone 200 dropped easily, for optimizing the product outward appearance, preferably, earphone standing groove 13's size corresponds with earphone 200's size for under accomodating the state, earphone 200 can fill earphone standing groove 13 entirely just, makes the wholeness of product outward appearance better. The earphone 200 completely stored in the earphone placing groove 13 cannot be taken out by a human hand, so the scheme is provided with the ejection mechanism 2, and the ejection mechanism 2 has the effect that when a user needs to take out the earphone, the earphone 200 can be ejected out by a certain height, so that a position is provided for grabbing the earphone by the human hand, and the user can conveniently take out the earphone 200 easily.

In order to hide the ejection mechanism 2 and facilitate manual operation, the ejection mechanism 2 in the scheme is indirectly controlled through the earphone 200 placed in the earphone placement groove 13, that is, when the earphone 200 is taken out or put in, the earphone 200 is pressed, the pushed earphone 200 is utilized to push the ejection mechanism 2 to move, and then the ejection mechanism 2 can be switched between the ejection position state and the storage position state.

In the earphone box 100 of the present embodiment, an ejection mechanism 2 is provided in the main housing 1, the ejection mechanism 2 has an ejection position state and a storage position state, when the earphone 200 in the earphone placement groove 13 needs to be taken out, only the earphone 200 needs to be pressed, the ejection mechanism 2 is pushed by the earphone 200, so that the ejection mechanism 2 is switched to the ejection position state to eject the earphone 200, and at this time, a person can easily take out the earphone 200; when the earphone 200 is placed, after the earphone 200 is aligned to the earphone placing groove 13, the earphone 200 is pressed again, the ejector mechanism 2 is pushed by the earphone 200, so that the ejector mechanism 2 is switched to a state of being in a storage position, and at the moment, the earphone 200 can be completely stored in the earphone placing groove 13, so that the problem that the earphone 200 is easy to fall off due to outward protrusion is avoided.

In summary, the earphone box 100 of the present embodiment omits the structure of the earphone box cover while maintaining the protection of the earphone 200 and facilitating the operation of taking and placing the earphone 200, which is beneficial to the downsizing of the earphone box 100 and convenient for the user to carry. Meanwhile, in the process of taking and placing the earphone 200, only the earphone 200 is needed to be pressed towards the same direction, and the taking and placing mode is simple and quick and good in experience.

In one embodiment, the ejection mechanism 2 includes an elastic member 24, a slider 21 and a limiting member 23, where the slider 21 is slidably mounted in the main housing 1, and the elastic member 24 is connected to the slider 21, and is capable of pushing the slider 21 to maintain a tendency toward the ejection position; the sliding block 21 is provided with a limiting part 212 corresponding to the storage position, and the limiting piece 23 can be matched with the limiting part 212 to lock the sliding block 21 at the storage position; pushing the stopper 23 into or out of engagement with the stopper 212 is achieved by pushing the slider 21 to move by the pressed earphone 200.

Specifically, in the state shown in fig. 3 to 4, the upper ejection mechanism 2 is used as a reference for description, and in the state of the storage position, the slider 21 is in the downward position, and the ejection mechanism 2 reserves enough space for the earphone 200, so that the earphone 200 can be completely stored in the earphone box 100; in the ejection position state, the sliding block 21 is in an upward position, and the ejection mechanism 2 can eject the earphone 200 upward, so that the earphone 200 can be taken out by a human hand conveniently. Regarding the control of the slider 21, the slider 21 is connected with an elastic member 24, and under the action of the elastic force of the elastic member 24, the slider 21 is continuously pulled to keep moving upwards, i.e. push the earphone 200 to eject. Referring to fig. 10, when the stopper 23 hooks the stopper 212 on the slider 21, the slider 21 can be restricted from ascending so that the slider 21 can be held in the storage position; when the limiting piece 23 is separated from the limiting portion 212, the elastic piece 24 pulls the slider 21 to move upwards, so that the slider 21 can jack up the earphone 200.

It will be appreciated that, in order to be able to switch the ejector mechanism 2 between the ejection position and the storage position by pressing, the relationship between the stopper 23 and the stopper 212 should be such that, when the slider 21 is pushed to move, the stopper 23 can enter or leave the engagement with the stopper 212.
