Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to the accompanying drawings the Noise Suppression Device based on collection of energy of the utility model embodiment is described.
Composition graphs 1 to Fig. 3, should comprising perforated plate 11, side plate 12, rear plate 13 and at least one friction generator 20 based on the Noise Suppression Device of collection of energy, wherein, perforated plate 11 being provided with at least one hole 14, for collecting noise; Side plate 12 mutually docks with perforated plate 11 and rear plate 13 respectively and forms cavity 15; At least one friction generator 20 is arranged on rear plate 13, for when noise enters cavity 15 by least one hole 14 on perforated plate 11, noise is converted to electric energy.
Wherein, as depicted in figs. 1 and 2, at least one hole 14 on perforated plate 11 can be circular hole, the random geometry such as square hole, prismatic hole, tri-angle-holed, five-pointed star hole, slotted hole; When hole 15 is circular hole, the diameter of hole 15 can be 0.5-1.5mm, and preferred value is 1mm.
In addition, the hole 14 on perforated plate 11 can be one, and also can be multiple, those skilled in the art can select as required, do not limit herein.When the hole 14 on perforated plate 11 is multiple, the spread configuration form of hole 14 on perforated plate 11 can be arbitrary form, such as: array can be adopted to arrange form and be arranged on perforated plate 11 by hole 14.
Wherein, at least one friction generator 20 can be the shapes such as cylinder, six prisms, eight prisms, and its quantity can be one, also can be multiple, and those skilled in the art can select shape and the quantity of friction generator 20 as required, does not limit herein.When the quantity of friction generator 20 is multiple, multiple friction generator 20 not only can be arranged on rear plate 13 by the form of array, also can be arranged on rear plate 13 by the form of stacked tiling, and be connected by mode that is in parallel and/or series connection between multiple friction generator 20.Particularly, as shown in fig. 4 a, the friction generator 20 of multiple hexagonal prism shape is arranged on rear plate 13 by the form of array; As shown in Figure 4 b, the stacked tiling of friction generator 20 of rectangular shape is arranged on rear plate 13, is also arranged on rear plate 13 by large-area friction generator 20.Wherein, at least one friction generator 20 can be fixed on rear plate 13 by forms such as stickups.
In the present embodiment, because perforated plate 11 has multiple hole 14, therefore be conducive to the collection to noise, noise is inhaled into the vibration that can cause friction generator after in cavity through multiple hole, thus makes friction generator contact friction convert noise to electric energy.
It should be noted that, the friction generator 20 shown in Fig. 4 a can and one_to_one corresponding relative with the hole 14 on perforated plate 11 be arranged, and also can not arrange by one_to_one corresponding, those skilled in the art can select as required, do not limit herein.
For the friction generator shown in Fig. 4 a, because the system class of the air layer composition corresponding thereto of each hole 14 on perforated plate 11 is similar to Helmholtz resonator, therefore the multiple holes 14 on perforated plate 11 can be regarded as the parallel connection of many Helmholtz resonators.Just air vibration in cavity 15 is excited when sound wave enters after hole 14, if when noise frequency is identical with this structure resonant frequency, in cavity 15, air just resonates, perforated plate 11 pore-throat place air column double vibrations, speed, amplitude reach maximum, friction is also maximum with damping, now, a noise part changes heat energy into, noise transition is electric energy by friction generator by a part, thus play high-efficient noise-reducing effect, and traditional noise-reducing structure can only to be heat energy by noise transition carry out noise reduction, far away from the noise reduction of this programme.
In addition, perforated plate 11 can be, but not limited to adopt the one in following material: corrosion resistant plate, aluminium sheet, iron plate, low carbon steel plate, copper coin etc.; Side plate 12 or rear plate 13 can be, but not limited to adopt one or more in following material: double glazing, compound glass, rubber, polyester fiber cotton, Sound-proof material, centrifugally glass-wool, rock wool, mineral wool and string etc., those skilled in the art can also select the material of perforated plate 11, side plate 12 and rear plate 13 as required.
Further, it should be noted that, rear plate 13 is provided with at least one wire guide (not shown), electrode output is connected with external devices by least one the wire guide (not shown) on rear plate 13, and the hole between at least one wire guide (not shown) and electrode output on rear plate 13 is filled by sealing substance, thus avoid noise to discharge from cavity 15, impact reduces the effect of noise and collection of energy conversion.
Friction generator in the utility model can adopt any one friction generator of the prior art, and such as: the friction generator of three-decker, four-layer structure and five-layer structure, those skilled in the art can select as required, do not limit herein.
The three-decker of the friction generator in the utility model, four-layer structure and five-layer structure is specifically introduced below by example one to example four.The friction generator of each Rotating fields at least comprises two surfaces forming frictional interface, and at least one formation in two surfaces of frictional interface is provided with micro-nano structure on the surface.
