Abstract
The utility model relates to a generating set, in particular to a noise electric generator. The electric generator comprises a generating coil and a magnet matched with the coil, the coil is fixed on a diaphragm sensing sound waves, and the vibration direction of the diaphragm is vertical to the magnetic force line of the magnet. The diaphragm is used for sensing the sound waves and drives the coil to move vertically to the magnetic force line, thus voltage is generated in the coil and is output and stored through the coil or used directly. The utility model is novel in design, simple in structure and practical, can be directly arranged in the occasions such as an airport, a factory and a Kara OK hall with heavy noise as well as roads with heavy sound to convert noise waves into electrical energy to be output, is energy saving and environment friendly, and changes waste into valuable.
Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), specifically a kind of noise generator that sound wave is converted to electric energy.
Background technology
No matter in the city or the rural area, sound wave is ubiquitous.Particularly in the road of airport, factory and prosperity, be full of various sound in the air, formed ubiquitous noise pollution.
As everyone knows, sound wave is a kind of energy, turns waste into wealth if can be used, and will be a kind of energy source endlessly.In the prior art, still do not find to utilize the device of acoustic wave generation.
The utility model content
The technical problems to be solved in the utility model provides a kind of noise generator that utilizes acoustic wave generation.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of noise generator comprises power coil and the magnet that matches with coil, and described coil stationary is on the vibrating diaphragm of perception sound wave, and the vibrating diaphragm direction of vibration is vertical with the magnet magnetic line of force.Vibrating diaphragm is used for the perception sound wave and drives the vertical magnetic line of force motion of coil, thereby produces voltage and export storage or directly utilization by coil in coil.
Because the center Oscillation Amplitude maximum of vibrating diaphragm, so coil is positioned at the vibrating diaphragm center, the relative magnet in the edge of vibrating diaphragm is fixed.
As the improvement to such scheme, above-mentioned vibrating diaphragm comprises the interior vibrating diaphragm of the direct fixed coil of outer vibrating diaphragm and center, and interior vibrating diaphragm developed area forms sealed hollow less than outer vibrating diaphragm developed area between outer vibrating diaphragm and the interior vibrating diaphragm.Outer vibrating diaphragm can be used for accepting large-area sound wave, and with transfer of vibration by transfer of air to the interior vibrating diaphragm, thereby vibrating diaphragm produces bigger vibration in making.
As the improvement to such scheme, above-mentioned interior vibrating diaphragm is positioned at outer vibrating diaphragm rear.Perhaps, the air duct by sealing is communicated with between outer vibrating diaphragm and the interior vibrating diaphragm.The both can reach the effect that maximum efficiency is transmitted sound wave.
The utility model modern design, simple in structure, practical, can directly be installed on the bigger airport of noise, factory, karaoke halls and the bigger occasions such as road of sound, the noise sound wave is converted to electric energy output, energy-conserving and environment-protective are turned waste into wealth.
Description of drawings
Accompanying drawing 1 is the utility model embodiment one structural representation; Accompanying drawing 2 is the utility model embodiment two structural representations; Accompanying drawing 3 is the utility model embodiment three structural representations.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
Embodiment one: as shown in Figure 1, the noise generator that this programme disclosed mainly is made up of interior vibrating diaphragm 31, power coil 1 and magnet 2.Wherein, interior vibrating diaphragm 31 is discoid, is used for the perception sound wave and produces vibration, can adopt Loudspeaker diaphragm commonly used now.1 of power coil is fixed in interior vibrating diaphragm 31 centers, moves along with interior vibrating diaphragm 31 vibrations.Magnet 2 is positioned at coil 1 center, and the direction of motion of coil 1 is vertical with magnet 2 magnetic lines of force, and when interior vibrating diaphragm 31 drove coil 1 motion, coil 1 formed cutting magnetic line movement, thereby in coil 1, form electromotive force, coil 1 two ends connecting wire is connected to formation electric current in back in the outside line.
This noise generator can be applicable to a lot of occasions, as is applied in airport, factory and the road, can connect charge in batteries with storage battery, and the power supply that also can directly connect with illumination or indicator light as light fixture uses, and occupation mode flexibly, conveniently.
Embodiment two: as shown in Figure 2, be another implementation of the utility model.We can say that this scheme is the improvement to technology among the embodiment one, can receive sound wave more delicately.The main improvement of this scheme is in interior vibrating diaphragm 31 the place aheads vibrating diaphragm 32 outside to be installed, and outer vibrating diaphragm 32 areas are greater than interior vibrating diaphragm 31 areas, and outer vibrating diaphragm 32 forms the cavity that seals with interior vibrating diaphragm 31.Because outer vibrating diaphragm 32 areas are bigger, so inspiration more, the sound wave of collection is more.To interior vibrating diaphragm 31, because interior vibrating diaphragm 31 areas are less, so interior vibrating diaphragm 31 amplitudes are bigger, the electromotive force that coil 1 produces is then bigger with the transfer of vibration of gathering for outer vibrating diaphragm 32, and generating efficiency is higher.Other part-structures of this programme are all consistent with embodiment one, are not described herein at this.
Embodiment three: as shown in Figure 3, this programme also is the improvement to embodiment one.The main improvement of the relative embodiment one of this scheme is to be provided with air duct 4 in interior vibrating diaphragm 31 the place aheads, air duct 4 ends are equipped with an outer vibrating diaphragm 32, interior vibrating diaphragm 31, outer vibrating diaphragm 32 and air duct 4 form closed cavity, and outer vibrating diaphragm 32 areas are greater than interior vibrating diaphragm 31 areas.Consistent with embodiment two principles, outer vibrating diaphragm 32 is sensitive more, and the sound wave of collection is more, thereby the electromotive force that produces in the coil 1 is bigger.Other part-structures of this programme are all consistent with embodiment one, also repeat no more at this.
Above-mentioned each scheme is the preferable implementation of the utility model; in addition; all right other implementations of the utility model need to prove that any conspicuous replacement is all within the utility model protection range under the prerequisite that does not break away from the present utility model design.
