Referring to fig. 2, 3 and 16, the top of the lower cover 100 has a first opening 101. The upper cover 200 is mounted with the second magnetic member 220, and the upper cover 200 is mounted on the lower cover 100 to open and close the first opening 101. When the upper cover 200 closes the first opening 101, the second magnetic member 220 is attracted to the first magnetic member 406.

If the wireless microphone 10 or the wireless receiver 20 is placed in a conventional microphone charging device, it is easy to fall out of the microphone charging device during the transition process, resulting in insufficient charging time and poor charging effect. In the microphone charging device provided by the present invention, the device accommodating groove 401 is used for accommodating the wireless microphone 10 or the wireless receiver 20, the charging assembly 300 charges the wireless microphone 10 or the wireless receiver 20 located in the device accommodating groove 401 through the charging hole 403, the upper cover 200 is covered on the lower cover 100, and the second magnetic member 220 is attracted to the first magnetic member 406, so that the upper cover 200 is stably and accurately closed to the first opening 101, the wireless microphone 10 or the wireless receiver 20 is prevented from shaking in the device accommodating groove 401, interference in the charging process is reduced, a technical problem of poor charging effect of the existing microphone charging device is solved, and the charging effect is improved.

For another example, one end of the upper cover 200 is rotatably coupled to one end of the lower cover 100 to open and close the first opening 101. Specifically, a plug is installed at one end of the upper cover 200, a socket is formed at one end of the lower cover 100, the upper cover 200 is rotatably installed on the lower cover 100 by inserting the plug into the socket, and the plug is not exposed and does not protrude out of the outer surface of the lower cover 100.

It should be noted that the charging assembly 300 has many structural forms.

For example, referring to fig. 2 and 5, the charging assembly 300 includes a first control board 310, a first battery 320 and a first conductive member 330, the first control board 310 is electrically connected to the first battery 320 and the first conductive member 330, respectively, one end of the first conductive member 330 extends into the charging hole 403, so that after the wireless microphone 10 or the wireless receiver 20 is received in the device receiving groove 401, the first conductive member 330 is electrically connected to the wireless microphone 10 or the wireless receiver 20, and the charging assembly 300 charges the wireless microphone 10 or the wireless receiver 20.

Accordingly, referring to fig. 9, the wireless microphone 10 includes a second control board 11, a second battery 12, and a second conductive member 13. The second control board 11 is electrically connected to the second battery 12 and the second conductive member 13, respectively. Referring to fig. 4 and 5, when the wireless microphone 10 is vertically inserted into the device accommodating groove 401, the first conductive member 330 is electrically connected to the second conductive member 13 through the charging hole 403, so that the first battery 320 charges the second battery 12 of the wireless microphone 10 through the first control board 310 and the first conductive member 330.

Optionally, the first conductive member 330 is a first charging contact and the second conductive member 13 is a second charging contact.

Optionally, the charging structure of the wireless receiver 20 is the same as that of the wireless microphone 10, so that when the wireless receiver 20 is vertically inserted into the device accommodating groove 401, the first conductive member 330 is electrically connected to the battery of the wireless receiver 20 through the charging hole 403, so that the first battery 320 charges the battery of the wireless receiver 20 through the first control board 310 and the first conductive member 330.

Specifically, referring to fig. 2 and fig. 11, the charging assembly 300 further includes a magnetic sensor 340 electrically connected to the first control board 310, and the magnetic sensor 340 is used for controlling on/off of a charging circuit of the first control board 310. Specifically, the first magnetic member 406 and the magnetic sensor 340 are spaced apart along the second direction Y, so as to avoid interference of the first magnetic member 406 with the magnetic sensor 340. When the upper cover 200 closes the first opening 101, the second magnetic member 220 and the first magnetic member 406 attract each other and trigger the magnetic sensor, so that the magnetic sensor 340 generates an electrical signal for controlling the conduction of the charging circuit of the first control board 310.

In this way, one second magnetic member 220 can be used to both generate an attraction effect with the first magnetic member 406 to stably close the upper cover 200 on the lower cover 100 and trigger the magnetic sensor 340 to work, so that the charging assembly 300 can only charge the wireless microphone 10 or the wireless receiver 20 when the upper cover 200 is closed.

Specifically, the projection of the second magnetic member 220 in the third direction partially falls on the first magnetic member 406 and partially falls on the magnetic sensor 340.

Further, the number of the second magnetic members 220, the first magnetic members 406 and the magnetic sensors 340 is two or more and is the same. For example, the number of the second magnetic members 220, the first magnetic members 406, and the magnetic sensors 340 is two, three, four, and so on.

When the upper cover 200 closes the first opening 101, the corresponding second magnetic member 220 and the corresponding first magnetic member 406 attract each other and trigger the corresponding magnetic sensor 340. When each magnetic sensor 340 is triggered, the charging circuit of the first control board 310 is turned on, so that the magnetic sensors 340 caused by the false touch of a user are reduced.

For example, in some scenarios, a user holds the inner case 400 by hand or wears some magnetic members close to the inner case, which causes one of the magnetic sensors 340 to be turned on, and when the number of the magnetic sensors 340 is more than two, the user is difficult to touch all the magnetic sensors 340 by mistake, thereby ensuring the charging safety.

Alternatively, the magnetic sensors 340 are serially connected in sequence, so that all the magnetic sensors 340 are triggered, and the charging circuit of the first control board 310 is turned on.
