Accompanying drawing explanation
Fig. 1 is the schematic diagram of the high-fidelity static sound box of the employing single-layer vibrating diaphragm that provides of the embodiment of the present invention;
Fig. 2 is the A-A cutaway view in Fig. 1.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As depicted in figs. 1 and 2, the high-fidelity static sound box of the employing single-layer vibrating diaphragm that the embodiment of the present invention provides, comprise the hollow housing by two framework 1 mix proportions, in described housing, centre position is provided with a single-layer vibrating diaphragm 2, described single-layer vibrating diaphragm 2 both sides are respectively interval with an opposite polarity pcb board 3, and the gap between described single-layer vibrating diaphragm 2 and pcb board 3 can guarantee can not produce any work flaw in assembling and the course of work; Described single-layer vibrating diaphragm 2 top layers are provided with the conductive layer of the high resistance of 500～1200 megaohms, and described pcb board 3 surfaces are provided with the conductive metal layer 31 of multiple concentric circles from inside to outside successively.
Particularly, offer equally distributed hole (not shown) on described pcb board 3, described hole can guarantee the penetrability of sound, is conducive to propagation and the transmission of sound.Totally 8 layers from the inside to surface of conductive metal layers 31 on described pcb board 3, are labeled with respectively alphabetical A～H; In addition, in order to reduce material consumption, the thickness of the conductive metal layer 31 on described pcb board 3 is 0.3～0.8mm.
Preferably, described single-layer vibrating diaphragm 2 adopts PET or PP material to make, and makes this single-layer vibrating diaphragm 2 have very excellent elasticity and anti-fatigue performance, and certainly, single-layer vibrating diaphragm 2 also can adopt other materials with this performance to make.
Particularly, the thickness of described single-layer vibrating diaphragm 2 is 4～12 microns; Conductive layer on described single-layer vibrating diaphragm 2 adopts deposit metal films or is coated on this single-layer vibrating diaphragm 2, so that this conductive layer has high resistance value.
Particularly, between described framework 1, pcb board 3, single-layer vibrating diaphragm 2, adopt the connected mode of rigidity, flexibility, rigidity and flexible and use to be assembled together, with ideally reproducing audio signal of electrostatic loudspeaker in assurance work fully, eliminate various to the dysgenic factor of sound.
Installation process of the present invention is as follows: (1) first, fixed frame 1 reliably, guarantees that it can not produce deformation in construction; (2) then, adopt flexible connection mode that framework 1 and pcb board 3 are combined, connecting media can be that glue or other can meet the material of instructions for use, but must assurance can bear long-term alternate load between the two; (3) next, the single-layer vibrating diaphragm 2 that is coated with conductive coating is combined on framework 1, the mode pcb board 3 is fixed together in employing, and strict guarantee single-layer vibrating diaphragm 2 has the initial tension meeting the requirements; (4) last, adopt rigidly connected mode to combine reliably all cell cubes that are fully assembled, meanwhile, also need to adopt elastic fastener to fix equably this two frameworks 1 in the surrounding of two frameworks 1; So far, complete the assembly work of static sound box, the utility model has been improved construction technology and construction equipment, has reduced workmen's quality and Capability Requirement, and conforming product rate improves greatly, and cost is minimized, and can realize the large production of scale of product.
The course of work of the high-fidelity static sound box of the employing single-layer vibrating diaphragm that the embodiment of the present invention provides is as follows: after energising, be connected with all the time the forward electrostatic potential of thousands of volts on single-layer vibrating diaphragm 2, a constant electric field environment is provided; When phonation unit is in running order, having passed through of being come by the circuit transmission of particular design boosted and the audio signal of polarity processing, under the impact of the high voltage electric field producing at single-layer vibrating diaphragm 2 places, make successively to the single-layer vibrating diaphragm 2 in digital H region, to produce favourable first after vibration from digital A, be that first digital a-quadrant produces vibration, then being that digital B region produces vibration, then producing vibration to digital C region, is finally that the region of digital H produces vibration.Like this, can simulate reliably sphere vibration, produce the sounding effect of true point sound source, when guaranteeing tonequality, can obtain the sufficiently high sound intensity.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
