DETAILED DESCRIPTION OF THE INVENTION

Figs. 1A to 3B are illustrations of a magnetic sound box device according to an embodiment of the present invention. The magnetic sound box device comprises a sound box 1 and an antimagnetic plate 2.
A plurality of speakers 11, a sound source signal processing module 12 and an electrical source module 13 are disposed in the sound box 1. The sound source signal processing module 12 comprises a wire connection interface 121 and a wireless connection interface 122 for connecting with an electronic device (not shown in the drawings) in order to receive sound source signals from the electronic device and to amplify the sound source signals, and to transmit the amplified sound source signals to the speakers 11 to play the sound source signals. The wire connection interface 121 is a sound source importing insertion hole for connecting with the electronic device electrically and obtaining the sound source signals. The wireless connection interface 122 is a wireless Bluetooth receiving and transmitting interface, and the sound source signal processing module 12 connects with a wireless Bluetooth receiving and transmitting unit of the electronic device via the wireless Bluetooth receiving and transmitting interface 122 in order to obtain the sound source signals. The electrical source module 13 comprises a chargeable battery unit 131 and a universal serial bus (USB) interface 132. The chargeable battery unit 131 supplies electricity to the sound source signal processing module 12. The sound source signal processing module 12 and the electrical source module 13 obtains the sound source signals and an external power supply via the universal serial bus (USB) interface 132, and the chargeable battery unit 131 is charged with electricity.
A coupling portion 14 is disposed on a back side of the sound box 1, and six magnets 141 are disposed on a left part and a right part of the coupling portion 14 respectively. The back side of the sound box 1 and the magnets 141 are covered by a back plate 142 of the coupling portion 14. A positioning element 143 like a positioning groove is concavely disposed at a middle of the back plate 142.
The antimagnetic plate 2 comprises an outer covering layer 21 and an inner antimagnetic sheet 22. The inner antimagnetic sheet 22 is made with an antimagnetic material or a magneto-conductive material, and the outer covering layer 21 is made with rubber. An upper edge of the antimagnetic plate 2 is connected with a lower periphery of the back side of the sound box 1, therefore the antimagnetic plate 2 can be movably connected to the periphery of the coupling portion 14, and the antimagnetic plate 2 can be turned relative to the sound box 1. Thereby, by turning the antimagnetic plate 2 to cover the coupling portion 14 of the sound box 1, the inner antimagnetic sheet 22 of the antimagnetic plate 2 is attracted to the magnets 141 of the coupling portion 14, and the magnetism of the magnets 141 of the coupling portion 14 can be blocked by the inner antimagnetic sheet 22.
Please refer to Fig. 4.

The metal plate 31 of the protection case 3 of the electronic device can be made with a metal, such as iron, which possesses magnetism after it is attracted or magnetized by the magnets 141. A position limiting structure 32 like a position limiting block is convexly disposed at a middle of the metal plate 31 in order that the position limiting structure 32 can be inserted into the positioning groove 143 of the sound box 1 to prevent the sound box 1 from sliding on the protection case 3 of the electronic device. Therefore, when the antimagnetic plate 2 is turned underneath the sound box 1 and the sound box 1 is magnetically attracted to a back side of the protection case 3 of the electronic device, the protection case 3 of the electronic device can be stand on a surface by the supporting of the antimagnetic plate 2 as shown in Figs. 5 and 6. Or the sound box 1 with the antimagnetic plate 2 can be turned upside down and the sound box 1 is magnetically attracted to the back side of the protection case 3 of the electronic device, the protection case 3 of the electronic device can be stand on a surface by the supporting of the sound box 1 as shown in Figs. 7 and 8. Thereby, a screen of the electronic device (e.g. a screen of a tablet computer) disposed inside the protection case 3 can be viewed with different angles.
Therefore, the magnetic sound box device of the present invention has the following advantages:
1. The magnetic sound box device is compact and convenient to carry around. The sound source signals from the electronic device can be played via the wire or wireless connection. After the magnetic sound box device is coupled with the back side of the protection case of the electronic device, it can support the protection case of the electronic device, and so that the practicability and additional value of the magnetic sound box device can be enhanced.
2. The magnetism of the magnets on the coupling portion of the sound box can be blocked by the antimagnetic plate in order to prevent other storage devices with magnetic materials from being damaged by the magnets before the magnetic sound box device is magnetically attracted to the metal case or protection case of the electronic device.
