The invention discloses a vibrating diaphragm type high frequency pressure regulating device which comprises a braking assembly and a vibrating diaphragm system. The device is controlled by an electronic control unit. When a braking pedal is trodden by manpower, the braking assembly can achieve the electronic braking on a vehicle. When a driving device in the braking assembly is damaged, manpower braking of the vehicle can be achieved. The vibrating diaphragm system achieves control over vibrating frequency of a vibrating diaphragm by controlling an electromagnetic coil, further regulates hydraulic pressure in a liquid cavity in the breaking assembly through reciprocating motion of iron cores arranged on the vibrating diaphragm, and regulating output pressure of a hydraulic system can be achieved. The vibrating diaphragm type high frequency pressure regulating device has the advantages that problem that vehicle braking performance can not be satisfied due to the fact of low change frequency of the hydraulic pressure and a small change amplitude value is solved, and the braking performance of the vehicle, the response speeds and the dynamic performance of systems needing to regulate hydraulic pressure quickly are effectively improved.
