BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to an earbud charging storage case, and more particularly to an earbud charging storage case of which first charging connectors fully contact with earbud charging connectors of a pair of earbuds accommodated in the earbud charging storage case.

2. The Related Art

As is known to all, a conventional earbud charging storage case is used for storing and charging an earbud matched with the conventional earbud charging storage case. The conventional earbud charging storage case has an accommodating groove for accommodating the earbud. A bottom wall of the accommodating groove is equipped with a first charging connector. A bottom of the earbud also has a second charging connector. When the earbud needs charging, the earbud is accommodated in the earbud charging storage case, and the second charging connector of the earbud is in contact with the first charging connector in the earbud charging storage case for charging the earbud.

However, when the second charging connector of the earbud is in contact with the first charging connector in the earbud charging storage case, the first charging connector of the earbud charging storage case will produce an upward resilience, so the first charging connector of the earbud charging storage case has no way of fully contacting with the second charging connector of the earbud.

Therefore, it is necessary to provide a new-typed earbud charging storage case, so that first charging connectors of the new-typed earbud charging storage case fully contact with earbud charging connectors of a pair of earbuds accommodated in the earbud charging storage case.

SUMMARY OF THE INVENTION

An object of the present invention is to provide an earbud charging storage case for storing and charging a pair of earbuds. The earbud charging storage case includes an earbud holder and a magnetic component bracket. Each earbud has a magnetic element. The earbud holder has a base portion. Two sides of a bottom surface of the base portion protrude downward to form two hollow accommodating portions. Two sides of a top surface of the base portion are recessed downward to form two lower receiving grooves, respectively. Insides of the two accommodating portions have two accommodating grooves penetrating upward through top surfaces of the two accommodating portions, respectively. Tops of the two accommodating grooves are connected and communicated with the two lower receiving grooves, respectively. The two lower receiving grooves and the two accommodating grooves together define two storing grooves, respectively. The pair of the earbuds are accommodated in the two storing grooves, respectively. Bottom walls of the two accommodating grooves open two charging holes for facilitating charging the pair of the earbuds. The magnetic component bracket is looped around the earbud holder. The magnetic component bracket opens two holding grooves corresponding to the two accommodating portions, respectively. The two accommodating portions pass downward through the two holding grooves. Several portions of a bottom surface of the magnetic component bracket are recessed upward to form a plurality of buckling grooves. Each of the plurality of the buckling grooves is equipped with a first magnetic component. A first magnetic north pole and a first magnetic south pole of the first magnetic component are transversely arranged. When each earbud stores in the earbud charging storage case, the magnetic element of each earbud is located between two of the first magnetic components of the magnetic component bracket, a height difference between top surfaces of the first magnetic components and top surfaces of the two magnetic elements is generated. The height difference between the top surfaces of the first magnetic components and the top surfaces of the two magnetic elements of the pair of the earbuds improve a mutual attraction characteristic of the first magnetic north poles and the first magnetic south poles of the first magnetic components, and the second magnetic north poles and the second magnetic south poles of the two magnetic elements of the pair of the earbuds, so a downward magnetic attraction force is generated among the two magnetic elements of the pair of the earbuds and the first magnetic components.

Another object of the present invention is to provide an earbud charging storage case for storing and charging at least one earbud which has at least one magnetic element. The earbud charging storage case includes an outer shell, an earbud holder, a magnetic component bracket, and an upper cover mounted on the outer shell. The earbud holder is received in the outer shell. The earbud holder has a base portion. At least one portion of a bottom surface of the base portion protrudes downward to form at least one hollow accommodating portion. At least one portion of a top surface of the base portion is recessed downward to form at least one lower receiving groove. An inside of the at least one accommodating portion has at least one accommodating groove penetrating upward through a top surface of the at least one accommodating portion. A top of the at least one accommodating groove is connected and communicated with the at least one lower receiving groove. The at least one lower receiving groove and the at least one accommodating groove together define at least one storing groove. The at least one earbud is accommodated in the at least one storing groove. The magnetic component bracket is positioned around the at least one accommodating portion. The magnetic component bracket has at least one first magnetic component magnetically attracting the at least one magnetic element of the at least one earbud. A height difference between a top surface of the at least one first magnetic component and a top surface of the at least one magnetic element is generated, so a downward magnetic attraction force is generated between the at least one magnetic element of the at least one earbud and the at least one first magnetic component.

Another object of the present invention is to provide an earbud charging storage case for storing and charging at least one earbud. The earbud charging storage case includes an outer shell having at least one plane side wall, an earbud holder received in the outer shell for accommodating the at least one earbud, a locating bracket positioned between the earbud holder and the plane side wall, a battery positioned between the locating bracket and the earbud holder, a rigid printed circuit board received in the outer shell, and an upper cover mounted on the outer shell.

As described above, the downward magnetic attraction force generated by each of the first magnetic components is exerted on corresponding one of the two magnetic elements by virtue of an up-down misaligned disposition way of each of the first magnetic components and the corresponding one of the two magnetic elements, so that two earbud charging connectors can resist against resilience forces generated by two first charging connectors of the earbud charging storage case to fully contact with the two first charging connectors of the earbud charging storage case to achieve a charging effect.
