DETAILED DESCRIPTION

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0032] The present utility model provides an earphone charging box 1, such as Figures 1 to 9As shown, the earphone charging box 1 includes an earphone compartment body 11 and a flip cover 12. The earphone compartment body 11 is provided with a storage cavity 111 for storing and charging the earphone 2; the flip cover 12 is rotatably mounted on one side of the top of the earphone compartment body 11 to open or cover the storage cavity 111. A main control circuit board 112 is provided at the bottom of the earphone compartment body 11, and a Hall sensor 112a is provided on the main control circuit board 112.

[0033] On the side opposite to the side where the flip cover 12 and the earphone compartment body 11 are rotatably connected, a first magnet 113 is disposed in the flip cover 12, and a second magnet 121 that is magnetically attracted to the first magnet 113 is disposed at the top of the earphone compartment body 11 corresponding to the first magnet 113. A magnetic rod 114 is also disposed in the earphone compartment body 11, one end of the magnetic rod 114 corresponds to the Hall sensor 112a, and the other end corresponds to the first magnet 113; the second magnet 121 is located beside the magnetic rod 114.

[0034] The earphone charging box 1 of the utility model is also provided with a magnetic rod 114 in the earphone compartment body 11, one end of the magnetic rod 114 corresponds to the Hall sensor 112a, and the other end corresponds to the first magnet 113. At the same time, the second magnet 121 is arranged beside the magnetic rod 114. In this way, when the flip cover 12 is closed on the earphone 2 compartment body, the first magnet 113 is close to the magnetic rod 114, and the magnetic conduction of the magnetic rod 114 can conduct the magnetic field of the first magnet 113 to the Hall sensor 112a. After the Hall sensor 112a senses the magnetic field, it generates a first signal so that the earphone charging box 1 controls the earphone 2, for example, controls the earphone 2 to disconnect the Bluetooth connection with the connected device; similarly, when the flip cover 12 is opened, the first magnet 113 is away from the magnetic rod 114, and the Hall sensor 112a cannot sense the magnetic field, thereby generating a second signal so that the earphone charging box 1 controls the earphone 2, for example, controls the earphone 2 to connect to the connected device through Bluetooth. Such an earphone charging box 1 can realize the direct placement of the Hall sensor 112a on the main control circuit board 112, and conduct magnetism through the magnetic rod 114, without having to set up a relatively expensive FPC circuit board (Flexible Printed Circuit, FPC), thereby reducing costs. At the same time, since the magnetic rod 114 can not only conduct magnetism, but also can be magnetically attracted to the first magnet 113 together with the second magnet 121 arranged on the side, the magnetic attraction and closing of the flip cover 12 can be achieved through the cooperation of the magnetic rod 114 and the second magnet 121, and the closing of the flip cover 12 is more secure.

[0035] Specifically, the magnetic rod 114 can be an iron rod, a cobalt rod, a nickel rod or an iron-cobalt alloy rod, etc., and the first magnet 113 and the second magnet 121 are magnets. When the flip cover 12 is opened to generate a second signal, the earphone charging box 1 controls the earphone 2 to connect to a connected device such as a mobile phone via Bluetooth, realizing an automatic connection function when the cover is opened. When the flip cover 12 is closed to generate a first signal, the earphone charging box 1 controls the earphone 2 to disconnect the Bluetooth connection with a connected device such as a mobile phone, realizing an automatic disconnection function when the flip cover 12 is closed.

[0036] Specifically, Figure 4 , Figure 7 As shown, a mounting post 115 is provided in the earphone compartment body 11, and a mounting cavity 115a is provided in the mounting post 115, which is open toward the main control circuit board 112 side, and one end of the magnetic rod 114 is inserted into the mounting cavity 115a. By providing the mounting post 115 in the earphone compartment body 11, and opening the mounting cavity 115a in the mounting post 115, the magnetic rod 114 can be conveniently and firmly installed in the mounting cavity 115a. The magnetic rod 114 can be fixedly installed in the mounting cavity 115a by interference fit, or can be glued to the mounting cavity 115a by glue.

In this solution, the mounting column 115 is disposed between the two storage chambers 111 and is respectively connected to the walls of the two storage chambers 111, and the structural strength of the mounting column 115 can be improved by utilizing the two existing storage chambers 111 structures, so that the structural strength of the mounting column 115 is stronger and it is not easy to be damaged during production and assembly.

[0038] Furthermore, the mounting column 115 includes two oppositely disposed plug-in column walls 115b, the two sides of the two plug-in column walls 115b are respectively connected to the wall surfaces of the two receiving cavities 111, and the two plug-in column walls 115b protrude outward to form a protrusion 115b1, and the protrusion 115b1 surrounds the mounting plug-in cavity 115a. By disposing two oppositely disposed plug-in column walls 115b and connecting them to the wall surfaces of the two receiving cavities 111 respectively, and forming the mounting plug-in cavity 115a through the protrusion 115b1 protruding outward, the mounting plug-in cavity 115a is ensured to be formed, and the connection between the mounting column 115 and the two receiving cavities 111 is made more secure. The two plug-in column walls 115b can be respectively connected to the two receiving cavities 111 in one piece.

[0039] The inner wall surfaces of the two protrusions 115b1 are both provided with axially extending ribs 115b11, and the provision of the ribs 115b11 facilitates the fixing of the installation cavity 115a to the magnetic rod 114, making the installation of the magnetic rod 114 more secure. Specifically, the inner wall surface of one protrusion 115b1 is provided with two ribs 115b11 located on both sides of the inner wall surface, and the inner side surface of the other protrusion 115b1 is provided with a rib 115b11 located in the middle of the inner wall surface.

[0040] like Figure 2 and Figure 7 As shown, two mounting studs 116 are provided in the earphone compartment body 11, and the two mounting studs 116 are integrally formed on the walls of the two storage chambers 111; the main control circuit board 112 is mounted on the two mounting studs 116 by screws. By providing the mounting studs 116 on the walls of the two storage chambers 111, a mounting position is provided for the main control circuit board 112, so that the main control circuit board 112 can be conveniently and firmly installed.

[0041] Furthermore, if Figure 7 As shown, a mounting groove 117 is provided in the earphone compartment body 11, and the second magnet 121 is installed in the mounting groove 117, so that the second magnet 121 can be firmly installed. In one embodiment, the mounting groove 117 can be surrounded by several convex strips, and the second magnet 121 can be fixed in the mounting groove 117 by glue. Specifically, the magnetic rod 114 is straight, which is convenient for production and assembly.

[0042] The utility model also discloses an earphone set, including an earphone 2 and the earphone charging box 1, wherein the earphone 2 can be stored in the storage cavity 111 and charged. Since the earphone set has the earphone charging box 1, it also has the same technical effects as the earphone charging box 1, which will not be described in detail.

[0043] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
