ELECTRICITY GENERATING DEVICE FIELD OF THE INVENTION

[0001] The present invention generally relates to the field of an electricity generating device. The invention, particularly relates to an electricity generating device which generates electricity using sound energy of the environment. The present invention uses fundamental concept of faraday law of electromagnetic induction for the generation of electricity.

BACKGROUND OF THE INVENTION

[0002] In today modem life charging a discharge appliance (battery) by electricity is very common, but what would happen if we charge the discharge appliance or battery with the help or source of sound vibration effect. The sound energy associated with the vibration of matter an abundant source of noise pollution, wherein the least of all types of pollution which most people ignore to recycle and turn into electricity sources. The purpose of this project is to design and develop a device that can make useful energy from noise known as noise pollution-based power bank, which can be used further for charging other electronic devices. Charging is performed with different gadgets that are most likely use power bank and found effective and efficient.

[0003] One of the main problems for this generation is pollution. However, recycling is the only solution that we can do to lessen it. These are noise pollution or noise disturbances and this is the kind pollution are being ignored which happened because there is no possible way to clean our surroundings from noise. On the other hand there is a way to recycle it into electrical energy produced by sound vibrations, these vibrations cause waves of pressure, which translate them into noise of varying levels change sound to mechanical to electrical energy.

[0004] A number of different type of the tools and methods for replacing/changing the electricity generating device are available in the prior art. For example, the following patents are provided for their supportive teachings and are all incorporated by reference: CN102820804A discloses a sound-electricity transducer made of novel piezoelectric materials. The acoustical-electrical transducer is capable of reducing noise pollution and simultaneously generating electric energy current in shortage and has the advantage of environmental-friendliness. A sound collecting device is designed into a horn and can provide a fixed base for a piezoelectric membrane while effectively receiving sound waves. The angle of an opening of the horn is controlled within 80-85 degrees since the sound is reflected back when being transmitted to a receiving plate and cannot be absorbed by the piezoelectric membrane if the angle is too large, and the sound waves cannot be effectively absorbed if the angle is too small. Meanwhile, a sound receiving device is provided with two active pivots which can be rotated at any angle to receive sound waves from different directions. When the sound waves are transmitted onto the piezoelectric membrane, electric energy generated via direct piezoelectric effect is stored inside a lithium battery, and an LED lamp can emit light when stored electric energy in the lithium battery is sufficient. However, this prior art document does not appear to disclose a device which can generate electricity using sound vibrating source like speaker.

[0005] Another prior art document, US20060082158A1 discloses a system to provide power comprising an acoustic-to-electric transducer electronically connected to a converter, said transducer optionally including a collector, said converter electronically connected to a diode, said diode electronically connected to, harmonized with, and providing energy to turn, a shaft of a flywheel, said flywheel comprising magnets that turn when the shaft turns to create an electric current in a stator that stores dischargeable power, said stator electronically connected to a rectifier, said rectifier connectable to an appliance requiring power. However, this prior art document does not appear to provide a portable device which can generate electricity with the environmental noise.

[0006] Another prior art document, US7358621B2 discloses an electric power generating and gaining device using sound waves and photic energy to generate magnetism together using a crystal microphone device providing a metallic film with metallic coil leading wires to sense and receive the frequency of external sound waves and pressure to form a vibratile magnetic field (N and S poles), using the magnetic field and leading wire thereof and the leading wire and coil magnetic field (N and S poles) of the solar cell to mutually cut to form electromagnet. However, this prior art document is costly and complex. Hence, unable to provide an economic device for electricity generation.

[0007] Another prior art document, US7567013B2 discloses a vibration-based electrical power generation is provided. In one aspect, a vibration-based power generator is embodied within a machine dampener and includes an electromotive power generation module and a piezoelectric power generation module. A power storage device is operably coupled to the electromotive power generation module and the piezoelectric power generation module. In another aspect, a device for generating electrical energy based is provided. The device includes a housing operably couplable to a source of vibration. The housing defines a chamber inside. A first circular permanent magnet is located within the chamber and has an outer diameter. A ring-type permanent magnet is located around the first circular permanent magnet and defines an annular space therebetween. At least one voice coil portion is located in the annular space and is coupled to a flexure structure to allow the voice coil portion(s) to move within the flux of the permanent magnets in response to vibration. However, this prior art document provides less efficient power generation with high operating risk.

[0008] Another prior art document, CN103236802A discloses a sound energy power generation device which is characterized by consisting of a sound energy acquisition device, a cantilever beam, a heavy object and piezoelectric ceramics; the rear end of the sound energy acquisition device is provided with an opening; the heavy object is arranged at the opening; and the rear side of the heavy object is provided with the piezoelectric ceramics. A sound energy conversion device can convert sound energy into electric energy, has a simple structure, is convenient to install and carry, and can adapt to the acoustical-electrical conversion on different occasions; and acoustical-electrical conversion devices for different occasions can be designed by changing the size of the sound energy acquisition device, the length of the cantilever beam, the size and the weight of the heavy object on the front end of the cantilever beam, and the size of the piezoelectric ceramics and considering the service life of a material. The sound energy acquisition device not only can be applied to sound energy collection but also can be widely applied to the collection of light, fluid and electromagnetic wave, so that the popularization of sound energy power generation is possible. However, this prior art document is complex and unable to generate electricity with noise of environment.

[0009] Another prior art document, JP2011097661A discloses a double-supported beam or a cantilever beam provided at the center of a movable weight between supports is not bent in a low frequency region due to its rigidity, and the amount of power generated by a piezoelectric element provided on the beam is extremely small. A support body 101 having a cavity 101a formed in the center, a cuboid movable weight 102 provided at the center of the cavity 101a and excited by mechanical vibration due to external vibration, and a support body In the piezoelectric vibration power generator 10 constituted by a pair of elastic beams 103a and 103b with a piezoelectric layer provided between the 101 and the movable weight 102, one end of each elastic beam 103a and 103b is a support 101. The other end is coupled to the upper end of the movable weight 102, and each elastic beam 103a, 103b has a folded structure. However, this prior art document does not appear to provide a device which can generate electricity using electromagnetic induction.

[0010] Another non-prior art document (Generation of electrical energy from sound energy IEEE Conference Publication) discloses Noise (sound) energy can be converted into viable source of electric power by using a suitable transducer. This can be done by using a transducer by converting vibrations caused by noise into electrical energy. An application is proposed for the same, in which a speaker and a transformer are used to convert noise produced by car horn into electrical energy. The vibrations created by noise can be converted into electrical energy through the principle of electromagnetic induction. The received signal was stepped up using a transformer. A similar setup was placed at distance of1 meter from the exhaust pipe of a 350 cubic centimeter engine of a motorbike. The demonstrated ideas probe into a clean and readily available source of energy.

[0011] However, above mentioned references and many other similar references has one or more of the following shortcomings: (a) Non-portable; (b) Unable to generate electricity with noise of environment; (c) High operating risk; (d) Complex and costly; (e) Less efficiency; and (f) Not generating electricity using electromagnetic induction. The present application addresses the above-mentioned concerns and shortcomings (and other similar concerns/shortcomings) with regard to provide a electricity generating device using environmental noise.

Before describing the detailed embodiments that are in accordance with the present disclosure, it should be observed that the embodiments reside primarily in combinations arrangement of the system according to an embodiment herein and as exemplified in FIG. 1 - FIG. 4.

[0030] In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of the arrangement of the device according to an embodiment herein. It will be apparent, however, to one skilled in the art, that the present embodiment can be practiced without these specific details. In other instances, structures are shown in block diagram form only in order to avoid obscuring the present invention.

[0031] Fig. 1 illustrates an electricity generating system 100 using sound energy of the environment for charging different electronic gadgets, according to an embodiment herein. In today modern life charging a discharge appliance (battery) by electricity is very common, but what would happen if we charge the discharge appliance or battery with the help or source of sound vibration effect. The electricity generating system 100 provides an electricity generating device 101, which may self-generate an electricity with the help of sound vibration effect later when the electricity start generating inside it then plug in that device to the discharged battery or appliances for charging it.

[0032] The electricity generating system 100 comprising a sound vibration source 102, vibration of sound 103, an electricity generating device 101, and a WSN device 104. The sound vibration source 102 may generate the vibration of sound 103 which may be received by the electricity generating device 101. Further, the electricity generated by the electricity generated device 101 may be used for charging different types of WSN devices 104.

[0033] The electricity generating device 101 may convert sound energy into electric energy using piezoelectric materials which may include but may not be limited to Lead zirconium titanate, Barrium titanate, Zinc oxide, or the like. Electricity can be generated directly from sound energy by piezoelectric effect. In the electricity generating device 101, the mechanical energy of sound is applied directly to a crystal (or possibly a ceramic) with strong piezoelectric characteristics, and the crystal may generate a small amount of voltage in response to the application of that mechanical energy (sound). A squeeze in the piezoelectric materials may generate a small voltage for the duration of the squeeze. When the crystal is released, another small voltage may be generated in the opposite polarity.

[0034] Fig. 2 depicts schematic diagram of electricity generating device 101 for sensing voltage through the vibration of sound waves, according to an embodiment herein. The electricity generating device 101 comprises a fan motor 201 with a rotating shaft, a magnetic bar 202, a sound vibration source 102, a plurality of magnetic coil 203, a voltmeter 204, a battery, a memory and a processor communicatively coupled to the memory. The sound vibration source 102 may include but may not be limited to horn of vehicle, speakers, noise of engine, or the like. The sound vibration source 102 may generate the vibration of sound 103 which may be received by the piezoelectric material used in the electricity generating device 101.

[0035] The electricity generating device 101 works on the fundamental concept of faraday law of electromagnetic induction which states that change in magnetic flux cause the production of electric current inside the coil. In the electricity generating device 101, magnetic flux between the two poles of the magnetic bar 202 generates. Once the sound vibration source 102 start sounding it would produce vibration by virtue of vibrating the tiny network of the fan motor 201 fitted between the magnetic bar across the border of the electricity generating device 101 start moving as consequence of that magnetic flux would changes which automatically will generate electricity inside the plurality of magnetic coils 203 in the electricity generating device 101.

[0036] Hence, the electricity generating device 101 may start possessing electricity which would be further use to electrically charge the discharged battery. So, in the electricity generating device 101, the principle of faraday law is used for producing electricity energy using the mechanical energy (sound vibration effect for the movement of shaft fan motor between the two magnet bars).

[0037] Fig. 3 depicts internal view of the electricity generating device 101 for generating electricity using noise, according to an embodiment herein. The internal view of the electricity generating device 101 depicts generation of sensing voltage using vibration of sound waves of speaker. The shaft of the fan motor 201 surrounded by two magnetic coils 203 having magnetic flux due to vibration of sound waves. If the Sound vibration from the sound vibration source 102 starts producing by the virtue of it, the kept fan shaft automatic starts rotating, as a consequence of this phenomena which is totally based on faraday law of electromagnetic induction, the rotating fan shaft disturb the static magnetic field across magnetic coil which will lead the cause for change in magnetic flux (=-dP/dt) with result of small amount of electric current generation in wire which will later obtained by the volt meter due the heavy vibration of electric shaft.

[0038] By way of an example, a person may place the electricity generating device 101 near the speaker used in home. The piezoelectric material used in the electricity generating device

101 may receive the vibration of the sound of speaker and the fan motor 102 may start rotating. It should be noted that the shaft of the fan motor 201 also rotates due to rotation of the fan motor 102. Hence, magnetic flux may be generated between the plurality of coils 203 and an electricity produces dur to that which may be stored in the battery. Further, the person may use the voltage in the battery to charge different electronic devices.

[0039] Fig. 4 depicts an exemplary method 400 of generating electricity using sound energy of the environment, according to an embodiment herein. At step 401, the electricity generating device 101 may receive vibration of sound from said sound vibration source 102 to generate magnetic flux between two poles of said magnetic bar 202. Further at step 402 the electricity generating device 101 may rotate said fan motor 201 fitted between said magnetic bar 202 due to vibration of sound received from said sound vibration source 102 for changing magnetic flux.

[0040] Further at step 403 the electricity generating device 101 may generate electricity in said plurality of magnetic coil 203 due to change in magnetic flux by rotating said fan motor 201. Further at step 404 the electricity generating device 101 may storing, by said electricity generating device 101, said electricity in said battery for further use.

[0041] It should be noted that the electricity generating device 101 receives vibration of sound to rotate said fan motor 201 though a piezoelectric sensor. Moreover, the sound vibration source 102 comprises speakers, horn of vehicle, engine producing high frequency sound, sound releasing from aircraft, aquatic material, or the like.
