Description of the invention: [Technical field to which the invention pertains] A flexible type The present invention relates to a sound generating device, particularly a sound generating device and a method of manufacturing the same. [Prior Art] In the industry's pursuit of light, short, and multi-functional product development trends, in order to improve the market competitiveness of products, the industry hopes to apply advanced technology to develop and manufacture products. In the case of Loudspeaker, the sounding principle of the speaker is to vibrate the diaphragm through the generation of electrical signals to produce sound. The sounds and sounds are more varied and can emit music, and can be applied to, for example, flat panel displays, notes. Consumer electronics such as computers, mobile phones, personal digital assistants (PDAs), and digital cameras, among which flat-panel displays are being developed with the help of Flexible Electronics technology; Related electronic products are produced from flexible % electronic components such as flexible plastic or thin metal substrates. The products manufactured by using such flexible technology have the characteristics of light weight, low cost and impact resistance, which not only have great development value, but also increase the imagination space of the designer on the product appearance and the user carrying Convenience, this technology is expected to bring revolutionary changes to industrial structure and human life. In terms of the type of the towerer, the speaker can be roughly divided into three types, such as a dynamic speaker, a piezoelectric speaker, and an electrostatic speaker. 19180 5 1293233, moving coil speakers are the most widely used and mature technology. The principle of motion is based on Fleming & hand rules, using magnetic field, current, and force to intersect at right angles. Control the reciprocating motion of the diaphragm piston to drive the air to produce sound, which is widely used in various types of electricity, audio, headphones and mobile phones. #, Due to the shortcomings of the congenital structure of moving coil speakers, it is not possible to flatten the volume, making this conventional technology unable to meet the trend of 3C products becoming smaller and flattering in home theaters. The σ piezoelectric speaker utilizes the piezoelectric effect of the piezoelectric material, and the additional electric field is used to induce the deformation of the material by the piezoelectric material, which is used to promote the diaphragm and the sound of the Diaphragm. However, such a conventional technique can be flattened: miniaturized, but limited by the fact that the resonant frequency of the piezoelectric material is high and the frequency I can be utilized is small, thus limiting the application field, and currently only the alarm is mostly 0 The role of the electrostatic speaker is to use the principle of the two-hole fixed electrode plate to hold the conductive diaphragm to form a capacitor to cry the ^ ^ ^ ^ (Condenser), by supplying the vibration with the direct & bias And the two AC electrodes are synchronized with the positive and negative phase of the AC voltage, and the electrostatic force generated by the tooth = 2 charge 'brings the brewing and will sound; radiate out. However, due to this kind of practice ^ ^ ^ ^ ^ in the white technology to supply the diaphragm bias requires hundreds to thousands of volts on the island, but must be external ρ.., ^ ^ shells back to the early and large expansion branches Therefore, it not only consumes energy, but also reduces the scope of the industry. At the same time, the patents related to the loudspeakers. Fi.fi ΟΟΛ 爻 patents include, for example, US Patent Announcement j 3, 646, 280, US Patent 3, 894, 199, Suo Meiwu Patent Notice No. 3, 892, 927, wearing an attack,, Mumu, Laos Patent Announcement No. 3, 896, 27 19180 6 1293233 _, US Patent Notice No. 3, The 935, 397 case, and the Taiwan Patent Publication No. 234232 and other technologies. Wu Guo Patent Publication No. 3,646, 28 () discloses an electrostatic speaker using an electret material. The structure of the patent consists of a main film conductor diaphragm, a pair of electrodes which are subsequently opened to the electret, and the 彖 and 彖 members are symmetrically clamped by the H-edge member in the middle of the two-charged resident version. In the middle, by using the conductive fiber and the electret interface 'can improve the electret is not easy to stick, and the electret opening and the back plate opening pair, the accuracy is not good, and the magnetic fiber density provides the diaphragm dustproof, The water vapor is blocked and the acoustic resistance coefficient is adjusted. |*隹&The patent application requires a hard suspension to fix the diaphragm to protect the diaphragm from tension, thereby allowing the diaphragm to vibrate by external force to drive the surrounding empty milk to produce sound' and the open back plate It is also hard, so it cannot be made into a type, a type, or a "冓. As a result, this kind of conventional technology does not have the flexibility to develop products that can be developed by H剌flexible electronic technology. Patent Publication No. 3,894,199 (4) discloses an electroacoustic transducer (Electroacoustic Transducer), in which both sides of the patent are positively charged, and the sensing conductor diaphragm is at a negative potential, which can replace the original DC biasing device for the diaphragm. At the same time, the two sides of the electrode from the transformer supply and port with the ν positive and negative phase parent flow signal, according to the electrostatic force formula, and the central diaphragm directly * bias, the push pull (push - electrostatic force, push the diaphragm vibration. However, 'this patent requires the use of a transformer to supply synchronous positive and negative phase AC signals. Therefore, two large capacitors and rectifying elements are required in the device; thus, 19180 (S) 7 1293233 = but the device is bulky and uses many components. The cost of Yemen's application of this conventional technology still requires the use of hard vibration and the same non-flexible function, and limits its application to US Patent Publication No. 3, 892, 927. Jielu-species with different widths ^ This patented structure is divided into two, electric and plate 'symmetrically holding the conductive diaphragm in the middle, using the same split electrode and the thunder-leaf win T is not used, and generates The electrostatic force of 98 and 3 corresponds to the effective resonance area of the diaphragm. The first resonance frequency of the diaphragm is different. Thus, the use of one or two electrode areas results in different resonance frequencies. The structure of the patent is complex, and the required cost is: 4:: is high and cannot be accepted by the general consumer. At the same time, the structure is composed of many electrodes with different widths. It is not known to be so large that it can not be applied to small electric sound elements such as hearing aids or earphones::::2 In the application of this conventional technology, additional voltage is required to generate DC = 'more power consumption, and the driving device is also large and complicated and expensive. In addition, the conventional technology still needs to use a rigid suspension to fix the diaphragm, and the opening moon plate is also hard, so it is not flexible. The patent publication No. 3,896,274 in the case of the State of the People's Republic of China The entire electret is adhered to the center of the electrode, and the number of holes is sighed around the electret. The electret has the advantages of stable charge and sticking, and is easy to stick. In this patent, the relative position is The electret, which resists the central position diaphragm, becomes a constant current bias potential. 19180 8 1293233 However, the opening of this patent is not evenly distributed, causing the diaphragm to vibrate and compress the air, the sound cannot be radiated smoothly, and The space between the electret and the diaphragm generates a standing wave, which makes the speaker inefficient and has other resonances formed. In addition, this prior art also requires a rigid suspension to fix the diaphragm 'and the back of the aperture The board is still hard, so there is still a lack of the aforementioned prior art. In the case of the US Patent Publication No. 3, 935, 397, a Wire Grid electrode electrostatic speaker element is provided with an insulating spacer. The diaphragm is symmetrically clamped between the two electrode bodies. The electrode structure of this patent is wound by a frame with a dense groove and end-tightened to form a mesh thumb. In addition to uniformly providing an electrostatic induction electrode to the diaphragm, Monomer dust protection is also provided. However, since the structure of this patent requires an additional device to generate direct pressure, it is more power-consuming, and the drive device is also relatively large and expensive. At the same time, the grid structure applied by such conventional technology is complicated and the price is high, so it is inconsistent to meet the market demand. In addition, Xi (4) = a hard suspension is required to fix the diaphragm, and the open back plate is also a hard type 2 which is inflexible and has a narrow application range. ΛTaiwan Patent Announcement No. 234232 reveals that a large static type of sound is crying, Jin, pulling out the pressure of crying:: The outer electrode is divided into multiple segments, and the device is changed into two:=! Different voltages of the electrodes. In the dance, the position of the DC polarizing film with different voltages and the central conductive diaphragm can be uniformly displaced. Force the knife cloth so that 19180 9 1293233, because the displacement of the diaphragm of the electrostatic electroacoustic device is very small, the movement is almost linear, even if the unequal electrostatic force is used to cause the displacement of the diaphragm in the whole region, it is not obvious. Let the sound quality improve. Moreover, the signal-driven amplifying device of the prior art is complicated, expensive, and bulky, and is suitable for applications such as earphones, hearing aids, and mobile phones that require micro-small speakers. In addition, the use of the conventional technology still requires a hard county to fix the diaphragm, and the aperture backplane is also hard, and cannot be made to be holdable. As such, there is also a lack of the aforementioned patents, so that it is impossible to develop products using flexible electronic technology. = In the above-mentioned conventional technology, the limitation of the pronunciation principle is that the fixed suspension boat does not have a flexible function, and has a large volume, a structure, a high frequency, a high energy consumption, and is not conducive to mass production. All kinds of shortcomings, such as how to effectively solve the problems that the prior art has to overcome in the current industry. It is [invention content]

When the invention is in the technical field of the invention, it has the usual knowledge that the thickness of each layer structure is modified. At the same time, (4) Extreme protection: through #_ flexible drive member 19 can also be used as a flexible drive member made of diaphragm material, but it is not the heart of the step, combined with the first The diaphragm and the first = 艮. -surface. In this embodiment, the skin of the skin is a smashing ϊβ + &隹"Haidi electrode 15 and the first >^ pole 6 coating-layer silver glue (not shown), and face to face 璧The first and second membranes are combined with the first surface of the second diaphragm. In this way, the first electrode 16 of the second diaphragm 13 grounds the first diaphragm 11 and the ground, and the straight __ 4 of the first diaphragm is charged by, for example, Xie Jun to make the diaphragm 11 and The second x internal charge is charged with piezoelectric characteristics. The principle of electroacoustic conversion of an electret piezoelectric diaphragm is as follows: when the electret is bipolar, it will have piezoelectric characteristics, and the molecular structure of the electret is non-, The polymer (Am〇rph〇us p〇l, er) is coated with a conductive material on both sides to form an electrode insulated from each other on both sides. After heating the structure to the glass transition temperature of the polymer (Glass Transition TemPerature), the two electrodes are used. The period is continuously charged with high voltage for a period of time to form a bipolar charge such as PVDF. In this embodiment, the two-pole H-book charge characteristic and the electrostatic force effect inside the electret material can be utilized, and when the electret diaphragm is subjected to external pressure, the deformation is perpendicular or parallel to the surface of the diaphragm. Therefore, if the diaphragm is fixed, the deformation 21 19180 (S) 1293233, which is perpendicular or parallel to the surface of the diaphragm, can be turned into a bending deformation, which in turn drives the air around the diaphragm to produce sound, =6 ® The °# shown by the electrostatic force formula and energy, the diaphragm force is the capacitance value of the positive body speaker multiplied by the internal electric field size and the external input sound voltage signal, if the diaphragm is stressed, the output sound is louder. Therefore, in this embodiment, a microporous structure can be fabricated inside the electret piezoelectric diaphragm (ie, the first vibrating membrane and the second vibrating membrane 13) to increase the surface area of the internal helium storage and significantly improve the permanent Stores the amount of charge and piezoelectric properties. Moreover, when the fluoropolymer film material has a nanoporous structure, a light transmissive electret material (for example, FEp) may be formed to make the flexible speaker in the embodiment transmit light to increase its applicability. . Therefore, it can be seen that the inside of the vibration plate of the present invention can include a nanometer structure to increase the output volume and light transmittance. The flexible speaker of the present embodiment and the method for manufacturing the same can be seen that the wide-spread electret piezoelectric film used for the vibration is driven by the flexible driving member to generate sound, and the structure is extremely simple and low in cost, and is very suitable for large-scale production: At the same time, because of the flexibility of the structure, it not only saves energy, but also saves energy. In addition, the Knocker's flexible speaker can be applied to the current development of flexible:: for example, in the display, in addition to the display; =, ::::, and can become a future portable The master of multimedia warfare is very valuable. Compared with the conventional technology, the flexible function = complex, tree-forming, and squeaky, the present invention provides a sleek speaker for use in a product with a weight characteristic of 19180 22 1293233, 'can save energy And the design of the structure can make the cost-lowering function and can be miniaturized, and the invention has the flexibility of the nickname, and does not require additional volume, which is advantageous for mass production and no additional consumption. Energy, and coherence, has solved the problems of the prior art. EMBODIMENT 2 - Figure 7 is a diagram of the flexible speaker of the present invention and its method of manufacture: In the above, the same or similar reference numerals are used to denote the same or similar elements, and the detailed description is omitted to make the description of the present case clearer and easier to understand. The first example is different from the first embodiment in that the first flexible driving member and the second flexible driving member in the first embodiment are composed of, for example, a flexible conductive aperture plate and a spacer, and the second embodiment The first of the examples can be used when the driving member and the second flexible driving member are 1, the second: Fig. 2, the second method in the embodiment ===; the second surface of one of the diaphragms The electrodes are formed without having to form two electrodes as in one embodiment. In addition, the first flexible driving member and the second flexible driving member may be, for example, a conductive metal sheet, and the conductive full-lined rainbow cymbal is, for example, a w-heart 1 having a staggered grid instead of the first For example, the opening and the protruding portion of the mesh may replace the first hanging portion as a spacing point. In this way, it is possible to simplify the two required parts: the first flexible and movable parts in the above embodiment can be electrically conductive, thus simplifying the method and the method of the first embodiment. Need material 19180 23 1293233 material. For example, in the case of the polar polymer film of the solar device, a film having a thickness of 4 μm can be fixed to a steel ring with a thickness of 4 μm, and the mode of the thin H is applied to the first ring. The film and the vibration of the second diaphragm (four) ΓΓ-surface) have a thickness of 〇.05 micrometers as the grounding lightning rod> genus mesh, the opening is all a thickness of 〇. 2 PCT The opening gold _ M , 3⁄4 ^ , 0 , , genus , 罔 is a conductive gold as an external signal input terminal • The six opening ratio can be, for example, 5〇%, and combined with the mesh of the open-hole metal mesh itself Can be fixed in the four '(four) (four) (four) open hole metal with a glue ▼. The subsequent method of production can be the same as the first and the same, so it will not be explained here. In combination with the foregoing, the present invention proposes a flexible speaker system that uses an external material structure of a speaker, and uses a soft pressure η ten as a vibration technique, so that the invention can be made into a large = speaker like a cloth. , can be pronounced after cutting into different shapes, and can change the structure of the drive / arbitrarily change the sound frequency band, and can be attached with the application product::= to meet the actual needs. In this way, it can be used in miniature 2, , and . The problem of the prior art is relatively solved. The above-described embodiments are merely illustrative of the principles of the invention and its functions are not intended to limit the invention. In any of the technical fields, there is a general spirit and a fan of the invention, and the above embodiments are: 亍二ΐ /, = double. For example, the first and second embodiments may be modified to simultaneously manufacture the first and second diaphragms, the electrodes, and the first and second pullable drivers, instead of first having a diaphragm, an electrode, and a removable drive member therein. For the group structure 19180 24 1293233, the unit ' is pressed after making another set of the same structure; or, the first embodiment can be modified to connect the input signal to the opposite electrode at the same time, for example, the first picture is connected to the same The signal of the first flexible driving member 17 can also be connected to the electrode 16 at the same time, and the signal connected to the second flexible driving member 19 can also be connected to the electrode 15 at the same time, that is, the electrode can be used as a grounding ground. Alternatively, an external enamel may be attached, and at this time, an insulating layer may be added between the two electrodes of the first embodiment. Alternatively, the supporting portion may be provided to the first diaphragm and the second diaphragm. Therefore, the scope of protection of the present invention should be as listed below.
