Abstract
The invention discloses a diaphragm electromagneticvibration exciter, and belongs to the field of machine manufacturing. The conventional electromagneticvibration exciter has the disadvantage that an elastic part is a plate spring or a spiral spring, has a big size and is hard to maintain. An elastic part of the diaphragm electromagneticvibration exciter is a platy elastic vibrating diaphragm. An armature is firmly connected to the geometric center of the elastic vibrating diaphragm. An electromagnet is connected with a power supply to attract the armature, the armature pulls the elastic vibrating diaphragm to deform and store energy; and the electromagnet is disconnected from the power supply, the elastic vibrating diaphragm resets and releases energy and drives the armature to obtain exciting force. The elastic vibrating diaphragm is wide in material selection space and provides a wide range of coefficient of stiffness. On equal conditions, a round elastic vibrating diaphragm can provide the coefficient of stiffnesswhich is many times higher than that of the plate spring. The axial geometric dimension of the elastic vibrating diaphragm is close to zero, the designed dimension of the electromagneticvibration exciter can be greatly reduced, and the amplitude can be convenient to adjust. Matched with the conventional power source technology, the diaphragm electromagneticvibration exciter can provide exciting force with different magnitudes, amplitudes and frequencies under the simplest structural design, and the application field of the electromagneticvibration exciter is greatly expanded.
