Embodiment Construction
[0026] An inertial vibrator based on a double-coil single-moving magnet according to the present invention will be described in detail below with reference to the drawings and embodiments.
[0027] Such as figure 1 As shown, an inertial vibrator based on a double-coil single moving magnet structure provided by the present invention includes: a moving magnet 1 , a casing 2 , an upper leaf spring 8 , a lower leaf spring 9 , an upper coil 13 , and a lower coil 14 . Both the upper leaf spring and the lower leaf spring 9 are annular plate-shaped elastic structures, which are used to support the moving magnet 1 in the casing 2, and limit the non-axial displacement of the moving magnet 1. The two sides of the moving magnet 1 The end is a symmetrically arranged annular tubular structure, so that the magnetic field generated by the moving magnet 1 forms a loop along the wall of the annular tubular structure, and an annular hole 17 is arranged on the outer end face of each annular tubul...

The invention provides an inertial vibration exciter based on a double-coil single-moving-magnet structure. The inertial vibration exciter comprises a moving magnet (1), an upper coil (13), a lower coil (14), plate springs and an outer shell (2). The two ends of the moving magnet (1) are of symmetrically-arranged annular tubular structures, and therefore a loop is formed by a magnetic field generated by the moving magnet (1) along the tube walls of the annular tubular structures. An annular hole (17) is formed in the outer end face of each annular tubular structure. The upper coil (13) and the lower coil (14) are symmetrically located in the two annular holes (17). After the reverse alternating current is introduced into the two coils, homodromous electromagnetic exciting force is generated among the upper coil (13), the lower coil (14) and the moving magnet (1), and opposite movement is generated between the moving magnet (1) and the outer shell (2) to form vibration excitation. The inertial vibration exciter has the higher force output capacity under the same size and weight, and stronger vibration can be excited.
Description
technical field [0001] The invention relates to the technical field of mechanical vibration, in particular to an inertial vibrator based on a double-coil single-moving magnet structure. Background technique [0002] A vibration exciter (referred to as an exciter, also known as an actuator) is a vibration excitation device that converts electrical energy into mechanical energy. Driven by an input signal, it excites the target in the form of an output force to generate the expected vibration. With the advancement of technology, in various fields such as scientific research, military affairs, automobiles, entertainment, etc., as people's demand for vibration generation or control becomes stronger, the application of vibration exciters is becoming more and more extensive. [0003] According to the different transducer devices, the exciter can be divided into electromagnetic type, piezoelectric type, magnetostrictive type, hydraulic type and other types. Among them, piezoelectri...
