Title:
A GENERATOR FOR PRODUCING INFRASOUND WAVE
Document Type and Number:
WIPO Patent Application WO/2009/018750
Kind Code:
A1
Abstract:
A generator for producing infrasound wave, which includes an electromagnetic
vibratory generator for forcing the air vibrate to produce the infrasound wave,
and a frequency control system for controlling the frequency of the vibratory
generator. The vibratory generator comprises a high magnetic permeability
long strip core beam (3), a plurality of rare earth permanent-magnet thin sheet
provided around the core beam, a high magnetic permeability thin board (4) placed
around the sheet and a plurality of layer coils supplied with alternate current
provided between them. The coils are connected with a vibratory plate (1) through
a nonmagnetic connected rod (2). The coils vibrate along the core beam, thereby
drive the vibratory plate vibrating to produce infrasound wave.
