Magnetic sensing based on the color center of nitrogen vacancy in diamond has been considered by scientists as a promising candidate for high sensitivity and integrated solid-state quantum sensors. In this paper,a displacement vibration detection method based on electron spin resonance effect is proposed, which takes the diamond nitrogen vacancy color center as the sensitive unit and uses its high sensitivity mechanism to the magnetic field intensity. We designed and built a vibration generator and a magnetic field detection system. The system consists of a fluorescence focusing system, a current carrying magnetic coil and a ruler. Here, we design an optimal parameter coil under the experimental conditions, change the inner diameter, outer diameter, height and current of the coil respectively, and use the control variable method to determine the final parameters. The fluorescence focusing system is responsible for efficiently exciting and collecting fluorescenceand determining the Zeeman splitting degree of electron spin effect. The current carrying coil is responsible for generating a high linear gradient magnetic field, and the scale is employed as the vibration source to generate vibration signals, so as to drive the current carrying coil to vibrate. In this way, the distance between the coil and the diamond is modulated, and the fluorescence intensity changes accordingly. Then, through rigorous static and dynamic experimental analysis, when the magnetic coil carries a current of 0.1 A, the displacement sensitivity is 25.11 nmHz12, and the theoretical displacement sensitivity is about 2.106 nmHz12, the minimum magnetic sensitivity limit is 0.198 nTHz12, the frequency of the vibration signal is 6.31 Hz, and the amplitude is 0.744 mm. The experiment verifies the feasibility of displacement vibration detection method. It provides a new way for high-precisiondisplacement and vibration detection methods.
