Abstract

The invention discloses a miniature columnar low-frequency vibrator, which belongs to the technical field of vibrators. Theminiature columnar low-frequency vibrator comprises an end cover, stator magnetic steel, vibrator magnetic steel, magnetic conductive sheets, a sleeve, a positioning shaft, a coil, a magnetic protection sleeve and a circuit board. A magnetic conductive area is formed by attaching a plurality of thin magnetic conductive sheets, and eddy current loss can be effectively reduced; the magnetic protection sleeve is arranged on the outermost layer of the cylinder, so that the magnetic induction intensity of a working air gap can be improved, an internal magnetic field can be shielded, and electromagnetic interference to peripheral electronic components is avoided; the vibrator is positioned by two ends of the positioning shaft, so that the operation is more stable; a traditional elastic piece or other elastic elements are replaced with the repulsive characteristic of the same polarity of the magnetic steel, wider frequency response can be obtained, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the field of vibrators, in particular to a vibrator with a smaller volume, a response frequency lower than 500 Hz and a greater impact force. Background technique [0002] In electro-acoustic equipment, the audio signal is restored to sound through the vibration of the sound film of the speaker. If you want to reflect the subwoofer and bass (below 200Hz), you must use a large-diameter speaker. For headphones and small audio equipment, due to the limitation of installation space, it is impossible to install subwoofer speakers, and only mid-frequency speakers can be used, which cannot reflect the dynamic and shocking effect of subwoofers. [0003] Most gamepads, e-sports peripherals, and VR helmets use DC eccentric motors to provide vibration. Car steering wheels, seats, and central touch screens are also beginning to introduce vibration feedback functions. However, the current ordinary vibrator has the defects of large volume, ...
