The lasers mixed with sound information are processed and sorted out through technical processing, and restored to sound, so that the sound of conversation in the room can be heard.

[0004] When facing a laser eavesdropping device, the existing anti-eavesdropping backpack cannot effectively deal with it, resulting in the inability to protect the user's personal information. Utility Model Content

[0010] A further improvement of the technical solution of the utility model is that: a side of the oscillation chamber away from the capacitor is fixedly connected to a fixing frame, and one end of the fixing frame is fixedly connected to a permanent magnet electromagnet.

[0011] A further improvement of the technical solution of the utility model is that one end of the receiving block is fixedly connected to a receiving bin, the inner wall of the receiving bin is overlapped with a natural permanent magnet, the middle part of one side of the inner wall of the receiving bin is fixedly connected to a conducting column, and the outer wall of the conducting column is overlapped with a copper coil.

[0012] A further improvement of the technical solution of the utility model is that one end of the copper coil is fixedly connected to a linkage tube, one end of the linkage tube is fixedly connected to a tympanic membrane, and the outer wall of the linkage tube is fixedly connected to a vibration membrane.

[0013] A further improvement of the technical solution of the utility model is that: the top of the fixing box is fixedly connected to a limit box, and the inner wall of the limit box is plugged with a power box.
