Title:
FAN AND THRUST GENERATION DEVICE WHICH USE SPEAKER
Document Type and Number:
WIPO Patent Application WO/2020/060078
Kind Code:
A1
Abstract:
The present invention relates to a fan using a speaker. When the speaker is waterproofed and sparse/dense waves generated by the speaker are made to be jetted through a jetting port in water, a compressed dense part, together with impact waves, generates thrust, and a sparse part is formed due to expansion by an expanding part. If the sparse part, at the time of being formed, is rapidly offset to uniformize the density of water from above/below the sparse part to the sparse part, a force of backwardly pulling a body is greatly offset due to the sparse part, and thrust due to the law of action and reaction is applied as is due to impact waves, so that a propellant can obtain thrust. In addition, soundwaves are stored and regenerated, so as to make the speaker ring at frequencies below audible frequencies and to form sparse/dense waves, so that wind comes out from the speaker. According to the present invention, by adjusting the amplitude of a sound to be larger or smaller, that is, by forming a variable resistor, the intensity of wind can be adjusted according to a volume size by sparse/dense waves.
