When a BLUETOOTH earphone is needed to be charged, the BLUETOOTH earphone is put into the earphone charger, the BLUETOOTH earphone then is conducted with the two charging resilient pieces, and meanwhile, through the anti-disengagement component, it is ensured that the BLUETOOTH earphone abuts against the charging resilient pieces to achieve continuous charging. Therefore, the neck-mounted portable power supply provided by the embodiments of the disclosure allows a user to charge the earphone while using the earphone. Moreover, the earphone charging cables of different colors or lengths can be quickly replaced, which is more flexible in use, and has low replacement cost and prolonged product service life.

First Embodiment

As shown in FIG. 1, an earphone charger adapted for various generations of BLUETOOTH earphones according to the first embodiment includes an earphone seat 10. The earphone seat 10 is fixedly disposed with two charging resilient pieces 11 for respectively abutting against a positive electrode conductive strip 20 and a negative electrode conductive strip 21 on a charging end of the BLUETOOTH earphone 2 (see FIGS. 4-5), and each of the charging resilient pieces 11 extends obliquely. A distance between the two charging resilient pieces 11 gradually decreases along an insertion direction (e.g., the direction as denoted by an arrow in FIG. 1) of the BLUETOOTH earphone 2. The earphone seat 10 is further fixedly disposed with an anti-disengagement component 12 used to prevent the BLUETOOTH earphone 2 from disengaging from the charging resilient pieces 11 during charging. The earphone charger of the embodiment has the advantage of being capable of charging BLUETOOTH earphones of various generations. A specific working process is as follows: the BLUETOOTH earphone 2 is moved to the earphone seat 10, the two charging resilient pieces 11 are deformed laterally under the pressing of the BLUETOOTH earphone 2, and the positive electrode conductive strip 20 and the negative electrode conductive strip 21 of the BLUETOOTH earphone 2 respectively abut against the two charging resilient pieces 11. Meanwhile, through the holding function of the anti-disengagement component 12 to the BLUETOOTH earphone, it can be ensured that the BLUETOOTH earphone is tightly attached to the charging resilient pieces 11 during the charging to thereby realize continuous charging. After the charging is completed, the BLUETOOTH earphone 2 is taken out, and the charging resilient pieces 11 can rapidly rebound.

For the first-generation or the second-generation BLUETOOTH earphone, the positive electrode conductive strip 20 and the negative electrode conductive strip 21 are disposed on a lower surface of the earphone; and for the third-generation BLUETOOTH earphone, the positive electrode conductive strip 20 and the negative electrode conductive strip 21 are located on an outer round surface of a lower end of the earphone. Therefore, when the inserted BLUETOOTH earphone 2 is the first-generation or the second-generation, a degree of being opened outwards of the two charging resilient pieces 11 is relatively large; and when the inserted BLUETOOTH earphone 2 is the third-generation, the degree of being opened outwards of the two charging resilient pieces 11 is relatively small. That is, a contact position between the first/second-generation BLUETOOTH earphone and the charging resilient pieces 11 is lower than a contact position between the third-generation BLUETOOTH earphone and the charging resilient pieces 11. In this situation, through the adaptive adjustment of the degree of being opened outwards of the two charging resilient pieces 11, it can be adapted to various generations of BLUETOOTH earphones, and thus is convenient to use and has good applicability.

In an embodiment, as shown in FIG. 1, the earphone seat 10 is further disposed with a resilient piece mounting block 13, and a mounting groove 180 for mounting the resilient piece mounting block 13. During mounting, the charging resilient pieces 11 are fixed to the resilient piece mounting block 13, and then the charging resilient pieces 11 and the resilient piece mounting block 13 together are put into the mounting groove 180 together, and thus it is convenient for mounting. The resilient piece mounting block 13 is located on a side where the distance between the two charging resilient pieces 11 is smaller, the resilient piece mounting block 13 is fixed to the earphone seat 10, and the resilient piece mounting block 13 is fixedly disposed with two fixing pieces 14 corresponding to the two charging resilient pieces 11 in a one-to-one manner. Each of the two fixing pieces 14 is fixed to an end of a corresponding one of the charging resilient pieces 11, and the fixing pieces 14 may be resilient pieces.

In an embodiment, as shown in FIG. 1, an end of the earphone seat 10 is fixedly disposed with the charging resilient pieces 11, and an opposite end thereof is disposed with a wire-passing through slot 181. The wire-passing through slot 181 is used to allow conductive wires to pass through and then form electrical connections with the charging resilient pieces 11, thereby conducting the charging resilient pieces 11 with an external power supply through the conductive wires.

In an embodiment, as shown in FIG. 1, the earphone seat 10 is further fixedly disposed with an anti-shifting resilient piece 15 used to prevent the BLUETOOTH earphone 2 from side-shifting during the charging. The anti-shifting resilient piece 15 and the two charging resilient pieces 11 are annularly distributed, so that the anti-shifting resilient piece 15 and the two charging resilient pieces 11 cooperate to position the BLUETOOTH earphone 2 during the charging. The three resilient pieces (i.e., the anti-shifting resilient piece 15 and the two charging resilient pieces 11) are triangularly arranged and are uniformly stressed, which is beneficial to the BLUETOOTH earphone 2 to tightly adhere to the charging resilient piece 11 to achieve continuous charging. It can also be seen from FIG. 1 that each of the charging resilient pieces 11 has a fixed end connected to a corresponding one of the two fixing pieces 14 and a free end away from the corresponding one of the two fixing pieces 14, and a distance between the free ends of the two charging resilient pieces 11 is smaller than a distance between the fixed ends of the two charging resilient pieces 11. In other words, the free ends are closer to the resilient piece mounting block 13 than the fixed ends. That is to say, the two charging resilient pieces 11 are disposed obliquely in a manner of approaching towards each other along the insertion direction of the BLUETOOTH earphone 2.

It is worth mentioning that, as shown in FIG. 1, the anti-disengagement component 12 includes a hollow rubber sleeve, that is, the anti-disengagement component 12 includes an annular elastic member having a hollow area. The hollow rubber sleeve is fixed to the earphone seat 10 and matched with the charging end of the BLUETOOTH earphone 2. The rubber sleeve is employed to limit the position of the BLUETOOTH earphone 2, so that the cost is low and the damage to the BLUETOOTH earphone 2 is small. Specifically, the hollow rubber sleeve may, for example, provide a downward friction force to the BLUETOOTH earphone 2 during the charging, and the two charging resilient pieces 11 and the anti-shifting resilient pieces 15 all are exposed to the hollow area of the anti-disengagement component 12.

Second Embodiment

The earphone charger adapted for various generations of BLUETOOTH earphone according to the second embodiment is shown in FIG. 2 to FIG. 5, the similarities with first embodiment will not be described again, and the differences are as follows.

As shown in FIGS. 2 to 5, the earphone seat 10 is disposed with an earphone insertion cavity 182 used to allow the charging end of the BLUETOOTH earphone 2 to be inserted. A side wall of the earphone insertion cavity 182 is disposed with two avoidance slots 183 corresponding to the two charging resilient pieces 11 in a one-to-one manner. The avoidance slots 183 respectively corresponds to ends (i.e., free ends) of the charging resilient pieces 11 facing towards an opening of the earphone insertion cavity 182 to avoid scratching the earphone seat 10.

As shown in FIG. 2 and FIG. 3, the anti-disengagement component 12 includes an annular rubber strip used to surround a periphery of the BLUETOOTH earphone 2 during the charging, that is, the anti-disengagement component 12 includes an annular elastic member having a hollow area. The annular rubber strip is fixed to the earphone seat 10, and is located at a side of the charging resilient pieces 11 facing towards the opening of the earphone insertion cavity 182. The rubber strip is used for limiting, which is low in cost and does not scratch the BLUETOOTH earphone 2. In addition, as can be seen from FIG. 3, the two charging resilient pieces 11 and the anti-shifting resilient pieces 15 are exposed to the hollow area of the anti-disengagement component 12, and the two charging resilient pieces 11 are obliquely arranged in a manner of approaching towards each other along the insertion direction (e.g., the direction as denoted by an arrow in FIGS. 4-5) of the BLUETOOTH earphone 2.

Third Embodiment

The earphone charger adapted for various generations of BLUETOOTH earphone according to the third embodiment is shown in FIG. 6 to FIG. 8, the similarities with first embodiment will not be described again, and the differences are as follows.

As shown in FIG. 6 to FIG. 8, the earphone seat 10 is disposed with an earphone insertion cavity 182 used to allow the charging end of the BLUETOOTH earphone 2 to be inserted. A side wall of the earphone insertion cavity 182 is disposed with two avoidance slots 183 corresponding to the two charging resilient pieces 11 in a one-to-one manner. The avoidance slots 183 corresponds to ends (i.e., free end) of the charging resilient pieces 11 facing towards an opening of the earphone insertion cavity 182 to avoid scratching the earphone seat 10.

As shown in FIG. 6 and FIG. 7, the earphone seat 10 includes an earphone seat body 111 used to mount the resilient piece mounting block 13 and a protection casing 112 used to accommodate the earphone seat body. The protection casing 112 is used to accommodate the resilient piece mounting block 13 mounted on the earphone seat body 111, the anti-shifting resilient piece 15 and the charging resilient pieces 11 fixed on the resilient piece mounting block 13, and the anti-disengagement component 12. In addition, the BLUETOOTH earphones of various generations can be partially accommodated in the protection casing 112 of the earphone seat 10 during the charging. Under the protection of the protection casing 112, all components are compactly accommodated in the protection casing 112 to prevent the various generations of BLUETOOTH earphones from affecting charging due to the side-shifting of components during the charging. Moreover, the earphone seat body 111 of the earphone seat 10 is further fixedly disposed with limiting posts 184, and two sides of the resilient piece mounting block 13 abut against the limiting posts 184 to prevent the resilient piece mounting block 13 from side-shifting, thereby preventing the charging resilient pieces 11 mounted on the resilient piece mounting block 13 from side-shifting during the charging, and ensuring the stability of the charging of the BLUETOOTH earphone.

As shown in FIG. 6 and FIG. 7, the anti-disengagement component 12 includes a hollow rubber sleeve used to surround a periphery of the BLUETOOTH earphone 2 during the charging, that is, the anti-disengagement component 12 includes an annular elastic member having a hollow area. The anti-disengagement component 12 further includes a limit block connected to the hollow rubber sleeve, and the limit block 121 is disposed with through grooves 1212 corresponding to the anti-shifting piece 15 and the two charging resilient pieces 11 in a one-to-one manner. The through grooves 1212 are used to allow the anti-shifting resilient piece 15 and the two charging resilient pieces 11 to pass through and expose the anti-shifting resilient piece 15 and the two charging resilient pieces 11 in the hollow area of the anti-disengagement component 12.

In addition, the limit block 121 is further disposed with limit grooves 1211 for accommodating the limiting posts respectively, and the limiting posts 184 are engaged with the limit grooves 1211, to prevent the anti-disengagement component 12 from side-shifting during the charging.

In summary, in the embodiment of the disclosure, the earphone seat, the resilient piece mounting block and the anti-disengagement component are tightly connected and mutually limited by providing the limiting posts, the limit grooves, and the through grooves positioning the anti-shifting resilient piece and the charging resilient pieces, so as to ensure that the components will not be side-shifting during the charging for the BLUETOOTH earphone. On the basis of being adapted for the charging of the BLUETOOTH earphones of various generations, the stability of the BLUETOOTH earphone during the charging is further improved.

Fourth Embodiment

As shown in FIG. 9 to FIG. 12, the neck-mounted portable power supply with detachable (i.e., split-type) earphone charging cables provided by the fourth embodiment includes a neck-mounted member 30 with a head and a tail not connected, two power supply boards 31 respectively fixed at two ends of the neck-mounted member 30 (i.e., a head end and a tail end, or a first end and a second end), and two earphone charging cables 32 corresponding to the two power supply boards 31 in a one-to-one manner. One of the power supply board 31 and the earphone charging cable 32 paired therewith is fixedly disposed with a power supply interface 33 at one end, and the other one of the power supply board and the earphone charging cable paired therewith is fixedly disposed with a plug 34 corresponding to the power supply interface 33 at one end. An end of each of the earphone charging cables 32 facing away from the corresponding power supply board 31 paired therewith is fixedly disposed with an earphone charger 35. The earphone charger 35 is, for example, the earphone charger described in the second embodiment, the earphone seat 10 is disposed with the two charging resilient pieces 11 that cooperate to supply power to the BLUETOOTH earphone, and the anti-disengagement component 12 used to prevent the BLUETOOTH earphone from disengaging from the charging resilient pieces 11 during the charging. The two charging resilient pieces 11 are electrically connected to the earphone charging cable 32. The neck-mounted portable power supply of this embodiment has the advantages of convenient replacement and flexible use. Specifically, when it needs to replace the BLUETOOTH earphone with another BLUETOOTH earphone of the same type, the BLUETOOTH earphone can be directly taken out from the earphone charger 35; and when the earphone charging cable 32 needs to be replaced, the plug 34 can be pulled out from the power supply interface 33. When a BLUETOOTH earphone is needed to be charged, the BLUETOOTH earphone is put into the earphone charger 35, the BLUETOOTH earphone then is conducted with the two charging resilient pieces 11, and meanwhile, through the anti-disengagement component 12, it is ensured that the BLUETOOTH earphone abuts against the charging resilient pieces 11 to achieve continuous charging. Therefore, compared with the neck-mounted BLUETOOTH earphone that integrates the BLUETOOTH earphone and a power supply, one end of the earphone charging cable is fixed to the BLUETOOTH earphone and the other end is fixed to the power supply board on a collar, the user cannot quickly replace the earphone charging cable or the BLUETOOTH earphone according to actual needs, which is inconvenient to use; while the neck-mounted portable power supply of the fourth embodiment allows a user to charge the earphone while using the earphone. In addition, the user can quickly change the earphone charging cable of different colors or lengths, which is more flexible in use, and has low replacement cost and prolonged product service life.

Among them, the neck-mounted member 30 may be made of hard plastic or rubber, and the plug 34 may be a universal serial bus (USB) plug or a TYPE-C plug.

As shown in FIG. 9 and FIG. 12, the neck-mounted portable power supply further includes two sets of mounting casings 38 respectively fixed at two ends of the neck-mounted member 30. Each of the power supply boards 31 is disposed in corresponding one set of mounting casings of the two sets of mounting casings 38 and fixed with the corresponding one set of mounting casings 38. The power supply interface 33 and the plug 34 may be respectively disposed on the power supply board 31 and the earphone charging cable 32. Each set of mounting casings are disposed with an opening 380 for exposing the power supply interface 33. The technical solution of this embodiment has advantages of stronger protection and more aesthetically pleasing products.

For example, each set of mounting casings of the two sets of mounting casings 38 are disposed with a wire-passing through slot 381 allowing the first conductive wire 311 and the second conductive wire 312 to pass through. The technical solution of this embodiment has the advantages of portability, compactness and better use experience. Specifically, only one battery 39 is required to supply power, and the overall product is lighter in weight. In addition, one set of conductive wires 310 are embedded into the neck-mounted member 30, which is neater and more beautiful, and the user will not be caught by the conductive wires when wearing or taking off the neck-mounted member 30.

As shown in FIG. 9 and FIG. 12, lower ends of the two sets of mounting casings 38 are arranged opposite to each other, the opening 380 is located at an upper end of the each set of mounting casings 38, which makes pulling and inserting of the earphone charging cable 32 more convenient.

As shown in FIG. 9 and FIG. 10, the earphone seat 10 of the earphone charger 35 may be disposed with an earphone insertion cavity 182. The charging resilient pieces 11 are located at a bottom of the earphone insertion cavity 182, and the earphone insertion cavity 182 corresponds to a flathead type BLUETOOTH earphone or a shallow-in BLUETOOTH earphone. The anti-disengagement component may include an elastic member, such as an annular elastic member, which is pressed by the BLUETOOTH earphone and fixedly disposed on a wall of the earphone insertion cavity 182. When in use, the BLUETOOTH earphone is inserted into the earphone charger 35, and the elastic member and the BLUETOOTH earphone are abutted against each other, so that the BLUETOOTH earphone can be quickly clamped on the earphone charger 35, and a good anti-disengagement effect is achieved; and when the BLUETOOTH earphone is further inserted, the BLUETOOTH earphone and the charging resilient pieces 11 are conducted, and the power charging can be performed. Among them, the elastic member may be an annular rubber strip (as shown in FIG. 10) or other elastic body.

In addition, it is worth noting that the earphone charger 35 may also be replaced with the earphone charger described in the first embodiment or the third embodiment.
