Abstract
The invention discloses a magnetic attraction vibration device comprising a power supply, a switch, and a lead wire. The switch is disposed on the lead wire, and the magnetic attraction vibration device comprises a high frequency vibrator. The lead wire is connected between the high frequency vibrator and the power supply, and a first magnetic sheet is disposed on the bottom part of the high frequency vibrator. The lower part of the first magnetic sheet is provided with a second magnetic sheet corresponding to the first magnetic sheet, and the lower surface of the first magnetic sheet is magnetically attracted to the upper surface of the second magnetic sheet. By adopting the above mentioned technical scheme, the magnetic attraction vibration device is advantageous in that the second magnetic sheet is disposed on the lower part of the circuit board, and by adopting the magnetic attraction of the first magnetic sheet to the second magnetic sheet, the high frequency vibrator can be fixedly disposed on the upper part of the circuit board, and then the circuit board can be vibrated along with the high frequency vibrator in a small-amplitude and high-frequency way, and therefore the line problem of the circuit board can be exposed, and the detection working efficiency can be improved.
