Further, the output slab 11 is provided with volume adjustment knob, power generation indicator light, 12V power output interfaces
And 5.5V standard USB power source output interfaces.
The present apparatus chooses frequency centered on f=144Hz according to Fibonacci sequence, and making Rc resonance circuits, (centre frequency is
144Hz positive and negative 10% is fine-tuning), 6.5 cun of loud speakers (a diameter of 16.7 centimetres) of connection, impedance are 8 ohm, power P=5 watt
And adaptation power amplifier (LM386 power amplifiers).Each component, is fixed in closed voice box line.Control twists joint line in corresponding position.
(speaker can improve 15% sound wave gain, the acoustic wave excitation input of constitution equipment)
According to input frequency f=144Hz, wavelength X=2.36 meter, Helmholtz resonator is done.
The calculation formula of the frequency and acoustic resonator size of Helmholtz resonator：
Wherein, f0Indicate the resonant frequency of Helmholtz resonator；
C indicates the velocity of sound；
S indicates the sectional area of the bottom opening of neck or the Helmholtz resonator 5；
D indicates neck or opening diameter；
L indicates the length of neck；

In addition to Helmholtz resonator opening half is open, the top of acoustic resonator, bottom, side face seam require hermetically sealed, finishing
(water, gas, without leakage).
In addition to the sealing fixing screws of bottom three, foreign in acoustic resonator.
3, the selection at Helmholtz resonator vibration power generation position
Acoustic resonator external surface area can be utilized, for generating electricity.
During conservative, present case only selects the lateral area of acoustic resonator for generating electricity.
The sides S=3.14*40*58.9=7397.84 square centimeters.
Acoustic resonator outer wall and electrification component bottom surface (one of electrode) the gapless bonding of conductive glue.All hairs
Electrical component circuit, which is helped, to be connected in parallel.
The budget of generated output：
It can the sides arrangement the piece number S/Sf=308 pieces.
Wherein Sf is the area of power generation monolithic module.
Output voltage V=5 volt, I=308*5mA=1540 milliamperes
The maximum general power of output：P=5 lies prostrate * 1.54 amperes=7.7 watts
It can two ports of mating output by booster circuit：
V=5.5 volt, I=1400 milliamperes=1.4 amperes
V=12 volt, I=640 milliamperes=0.64 ampere
The power supply or charging directly to small-power electrical equipment are met.
The resonance pairing process of sound source and Helmholtz resonator is as follows：
1, sound wave source switch is opened, 2/3 position is transferred in volume torsion or arrives maximum.At this point, Helmholtz resonator should produce
Raw slight resonance.
2, it adjusts frequency trim to turn round, resonance is made to be enhanced to maximum.
3, three screws at the top of equipment are adjusted separately, Helmholtz's sympathetic response mouth and sound wave source speaker of voice box can be changed
Distance (about 5.5 centimetres adjustable).Sound wave source and resonant wavelength error when manufacture acoustic resonator are solved, makes acoustic resonator resonance best.
(1,2,3 steps observe power generation indicator light to most bright as benefit.)
4, the voltage of detection power generation delivery outlet is in normal value.
Operation principle is as follows：
Sound wave source is opened, resonator receives sound source excitation and does resonance excitation, shakes potential energy until resonator generates, will be mechanical
Potential energy is changed into electric energy output.(adjusting device output voltage can be used as the power supply or charging output end of a variety of electrical equipments)
It is shaken by resonant cavity autoexcitation with continuous special sound, wave source, the resonance potential energy of cavity (acoustic resonator) is for shaking
Dynamic power generation, at rectifying and voltage-stabilizing or boosting in after, equipment is powered or is charged.
Using resonance potential energy much larger than this advantage of excitation energy.
Major part:Sound source, resonant cavity (acoustic resonator) power generation (resonant cavity, vibration power generation), rectification output, noise reduction are made an uproar only.
Note：The equipment is applicable in the power generation of city low noise resonator, can be used as green power supply.
The resonant frequency of adjustment resonator is not discharged in later stage.Adapt to environmental demand, compact apparatus.Array is cumulative provide compared with
Big energy power supply.
