An earphone charger 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 5.

As shown in fig. 1, the earphone charger 100 according to the embodiment of the present invention includes: body 1 and charging connector 2.

As shown in fig. 1, the body 1 has a working surface 11, and the working surface 11 is provided with an insertion hole 12 for inserting the earphone rod 5. The charging connector 2 is arranged on the working surface 11, the charging connector 2 comprises a positive connector 21 and a negative connector 22, the positive connector 21 is circular or arc-shaped and surrounds the jack 12, and the negative connector 22 is circular or arc-shaped and surrounds the jack 12. That is, the positive tab 21 and the negative tab 22 are wound around the insertion hole 12. For example, the positive tab 21 and the negative tab 22 are concentrically arranged, and the centers of the positive tab 21 and the negative tab 22 are in the insertion hole 12.

As shown in fig. 1 and 2, the positive electrode tab 21 and the negative electrode tab 22 may each have a circular ring shape. Alternatively, as shown in fig. 3, the positive electrode tab 21 and the negative electrode tab 22 may each have a circular arc shape. In another embodiment, the positive electrode tab 21 is circular and the negative electrode tab 22 is circular, or the positive electrode tab 21 is circular and the negative electrode tab 22 is circular. It is not limited here whether each joint is circular or circular arc-shaped in particular.

As shown in fig. 1 to 3, the positive electrode tab 21 and the negative electrode tab 22 are spaced apart in the radial direction of the circular ring shape or circular arc shape. Taking the positive electrode tab 21 as a circular ring as an example, that is, the positive electrode tab 21 and the negative electrode tab 22 are arranged along the radial direction of the circular ring, and the positive electrode tab 21 and the negative electrode tab 22 are spaced apart from each other, so as to avoid short circuit caused by the erroneous contact between the positive electrode tab 21 and the negative electrode tab 22.

Since the positive electrode tab 21 and the negative electrode tab 22 are spaced apart in the radial direction, the positive electrode tab 21 and the negative electrode tab 22 are also spaced apart from the insertion hole 12. As shown in fig. 4, the radius of the positive tab 21 is r1, the radius of the negative tab 22 is r2, r1 is not equal to r2, and a spacer 23 with a width of r0 is formed between the positive tab 21 and the negative tab 22, so that the positive tab 21 and the negative tab 22 can be spaced apart in the radial direction.

Thus, when the earphone charger 100 is used, as shown in fig. 10, if the positive terminal 41 and the negative terminal 42 for charging on the earphone 200 are also configured to match with each other, the earphone charger 100 can be properly charged by the electricity regardless of whether the earphone 200 is a left-ear earphone or a right-ear earphone.

Specifically, as shown in fig. 10 and 11, when the distance between the positive terminal 41 and the center of the earphone rod 5 is n1, the distance between the negative terminal 42 and the center of the earphone rod 5 is n2, and the distance between the positive terminal 41 and the negative terminal 42 is n 0. When the earphone rod 5 of the earphone 200 is inserted into the jack 12, the positive terminal 41 directly falls on the positive connector 21, and the negative terminal 42 directly falls on the negative connector 22 when n1 is equal to r1, n2 is equal to r2, and n0 is equal to r 0. Even when the positive tab 21 or the negative tab 22 has a circular ring shape, the user can easily adjust the angle of the earphone head 4 so that the positive terminal 41 falls on the positive tab 21 and the negative terminal 42 falls on the negative tab 22. The arrangement can avoid the situation that the positive electrode and the negative electrode are reversely connected, so that the earphone 200 can be correctly charged from the earphone charger 100 in a contact manner.

The scheme ensures that the jack 12 does not need to be divided into a left ear charging hole and a right ear charging hole, or the scheme ensures that the jacks 12 finish the unification of the positions of the positive electrode and the negative electrode. Therefore, no matter the earphone of the left ear or the earphone of the right ear, as long as the distance between the positive and negative terminals of the earphone 200 and the earphone rod 5 is consistent with the corresponding radius of the corresponding connector, the correct power connection can be realized after the earphone 200 is inserted into the jack 12, so that the earphone 200 can be more conveniently placed during charging.

It can be understood that, in order to avoid the left and right earphones from being inserted reversely in the prior art, a fool-proof structure is usually arranged. For example, in some schemes, can set up the columniform lug on the earphone pole of left earphone, charge and set up the columniform recess in the left ear charging hole of box, then set up square lug on the earphone pole of right earphone, charge and set up the square recess in the right ear charging hole of box, the earphone pole of left earphone can only inject left ear charging hole like this, the earphone pole of right earphone can only inject right ear charging hole. With such a fool-proof structure, the user can only find that the insertion is not performed when the insertion is reversed, which results in the need of reinsertion. However, according to the scheme of the application, the jack 12 unifies the power connection characteristics of the left ear charging hole and the right ear charging hole, the earphone charger 100 does not need to be provided with a fool-proof structure, and the structure of the earphone charger 100 is simplified.

In the scheme of the application, the positive electrode connector 21 and the negative electrode connector 22 are arranged to be circular or arc-shaped, after the earphone rod 5 of the earphone 200 is inserted into the jack 12, the positive electrode terminal and the negative electrode terminal are easily contacted with the positive electrode connector and the negative electrode connector at one time, and the probability that a user readjusts the angle of the earphone 200 on the earphone charger 100 is small, so that the convenience of placing the earphone 200 is further improved.

In the present embodiment, the positive electrode tab 21 may be disposed outside the negative electrode tab 22 as shown in fig. 1, or the positive electrode tab 21 may be disposed inside the negative electrode tab 22 as shown in fig. 2.

In some embodiments, the jack 12 of the headset charger 100 is a cylindrical hole, and the positive tab 21 and the negative tab 22 are both disposed concentrically with the jack 12. Compared with holes with other shapes (such as polygonal shapes like oval, square and the like), the circular jack 12 is more convenient and quicker to insert the earphone, and the hole is not easy to be blocked when the earphone jack is inserted.

As shown in fig. 4, the radius of the positive tab 21 is r1, the radius of the negative tab 22 is r2, and a spacer 23 having a width of r0 is formed between the positive tab 21 and the negative tab 22. The positive electrode tap 21 and the negative electrode tap 22 are concentrically arranged with the jack 12, and the width r0 of the spacing band 23 is uniform, so that the earphone can be charged smoothly even if the earphone 200 is rotated in the jack 12 after the earphone 200 is inserted into the jack 12.

In some embodiments, as shown in fig. 11, the positive tab 21 and the negative tab 22 are both protrusions disposed on the working surface 11, and the groove between the positive tab 21 and the negative tab 22 is used for spacing, that is, the spacer tape 23 forms a groove. The height of the positive electrode tab 21 and the negative electrode tab 22 is higher than that of the working surface 11, so that when the working surface 11 is deformed or foreign particles are on the working surface 11, the positive electrode tab 21 and the negative electrode tab 22 protrude from the working surface 11, the positive electrode tab 21 and the negative electrode tab 22 can still be easily contacted with the earphone 200, and the connection between the positive electrode tab 21 and the negative electrode tab 22 and the earphone 200 is more stable.

Further, the heights of the positive electrode tab 21 and the negative electrode tab 22 are equal to each other with respect to the working surface 11, so that the stability of the earphone 200 during connection is ensured, and the earphone is simple and beautiful. In addition, if the earphone charger 100 is impacted on the working surface 11, for example, when a bump occurs, the positive electrode tab 21 and the negative electrode tab 22 have equal heights, so that the positive electrode tab 21 and the negative electrode tab 22 can differentiate the impact force, and the impact force is prevented from being concentrated at one of the tabs and being damaged.

In some embodiments, as shown in fig. 1, the working surface 11 of the earphone charger 100 is provided with two spaced apart jacks 12, and each jack 12 is provided with a circular positive connector 21 and a circular negative connector 22. In daily life, generally all can use two earphones simultaneously, set up two spaced apart jacks 12 on the earphone charger 100, both satisfied people daily demand to the earphone charging, the volume of earphone charger 100 is also less simultaneously, conveniently carries. As shown in fig. 7 and 8, when the earphone charger 100 is used to charge earphones, two earphones may be charged at the same time, or only one earphone may be charged.

Of course, the present invention is not limited to this, and as shown in fig. 5, only one jack 12 may be provided on the headset charger 100, and when there are two headsets 200, the two headsets may be alternately charged. The design of the single jack 12 simplifies the structure of the earphone charger 100, reduces the production cost, and has small volume and convenient carrying.

In some embodiments, the headset charger 100 is provided with a plurality of jacks 12, which can be placed in a public area for a plurality of users.

In some embodiments, the headset charger 100 further comprises: a cover body 3 for covering the working surface 11, the cover body 3 being rotatably connected to the body 1. The cover 3 can protect the internal structures of the earphone 200 and the earphone charger 100 from entering foreign matters (dust, water, etc.), and can also prevent the earphone 200 from falling off from the jack 12 of the earphone charger 100, so that the connection between the earphone 200 and the earphone charger 100 is more stable and the carrying is convenient.

In summary, the headset charger 100 disclosed in the present application enables a TWS headset user to arbitrarily place the headset 200 in the headset charger 100 (without distinguishing between the left and right ears), and achieve the effect of contact charging.

The structure of the earphone 200 according to an embodiment of the present invention is described below with reference to fig. 6 to 11.

As shown in fig. 6, the earphone 200 according to the embodiment of the present invention includes: a headset head 4 and a headset stem 5. The earphone head 4 is provided with a positive terminal 41 and a negative terminal 42 for charging, the earphone rod 5 is connected to the earphone head 4, and the distances between the positive terminal 41 and the negative terminal 42 and the earphone rod 5 are different.

The earphone 200 according to the present invention can be used with the earphone charger 100 according to the above embodiments. Specifically, the distance between the positive terminal 41 and the center of the earphone rod 5 is n1, the distance between the negative terminal 42 and the center of the earphone rod 5 is n2, and the pitch between the positive terminal 41 and the negative terminal 42 is n 0. When the earphone rod 5 of the earphone 200 is inserted into the jack 12, the positive terminal 41 directly falls on the positive connector 21, and the negative terminal 42 directly falls on the negative connector 22 when n1 is equal to r1, n2 is equal to r2, and n0 is equal to r 0.

The matching arrangement of the distances can avoid the situation that the positive electrode and the negative electrode are reversely connected, so that the earphone 200 can be correctly charged from the earphone charger 100 in a contact manner.

In some embodiments, as shown in fig. 6, the positive terminal 41 and the negative terminal 42 of the earphone 200 are pins respectively, and the pins have an extending end extending out of the earphone head 4, so that the pins can be prevented from being influenced by the structure of the earphone head 4 when being connected to the earphone charger 100, the connection between the pins and the earphone charger 100 is more stable, the overall structure of the pins is smaller, the user experience of the user on the earphone 200 cannot be influenced, and the overall beauty of the earphone 200 is also ensured.
