The invention discloses a noise generator, which comprises a single sound production body and a base, wherein the base is used for placing the single sound production body; the base is arranged on a bracket; a battery and a controller are also placed on the bracket; the controller is connected to the battery and the single sound production body; the single sound production body comprises a sound absorption ear; the sound absorption ear is sequentially connected with a primary transducer and a secondary transducer; the primary transducer comprises a sound transmission channel which is connected to the sound absorption ear; one end of the sound transmission channel is sealed by a PVDF film to form a pipeline with a closed end, so that a sound wave and the PVDF film generate resonance; the secondary transducer comprises an induction coil which is arranged at the other end of the PVDF film; the induction coil is arranged in a permanent magnet; and an iron core is arranged in the induction coil. According to the noise generator, the noise energy is absorbed by the single sound production body and is converted into available electric energy while the noise is not directly removed, so that the target of eliminating the noise is reached; the noise is utilized to generate electricity; and waste is changed into treasures, so that useless environmental noise is changed into available electric energy, and recycling and utilizing of an energy source are achieved.
Description
technical field [0001] The invention belongs to the technical field of energy conversion, in particular to a noise generator capable of generating electricity by using noise. Background technique [0002] Facing the pressure of the global energy crisis and environmental pollution, low-carbon economy and green development are imperative. How to make more reasonable use of the energy around us and turn waste into treasure is an important way to solve the energy crisis. [0003] With the development of modern industry, environmental pollution is also produced. Noise pollution is actually a kind of energy pollution. According to relevant research, the energy of noise is very large. A jet aircraft with a noise of 160 decibels The noise power within 20 meters can reach 10 kilowatts, that is to say, it can generate 10 kilowatt-hours of electricity in one hour. If a noise generator is installed at the airport, the electric energy generated by aircraft taking off and landing every d...
