Description of the Invention: [Technical Field] The present invention relates to a planar speaker, and more particularly to a planar electrostatic speaker having a support structure. [Prior Art] Nowadays, vision and hearing are the two most direct sensory responses of human beings. Therefore, scientists have been developing various regenerative visual and auditory related systems for a long time. At present, the way of regenerating the speaker is mainly dominated by the moving coils to dominate the entire market. However, with the increasing demands on sensory quality in recent years, and 3C products (c〇mputer, umCati〇n, consumer dectr〇nics) in the pursuit of short and light and soothing two provinces 'light L ergonomic needs design Yang's i-machine: 2 with large-sized flat speakers 11 'still small to the Walkman = a few 丄, the phone, in the foreseeable tomorrow, this aspect of the technology will have a big need for the development of the application. (4) At present, the classification of electroacoustic sounds is mainly divided into direct and indirect light-emitting types. The ° method is roughly divided into moving coil type, piezoelectric type and electrostatic type speaker φ. The ring type speaker is currently used the most lucrative, 弋%ί thief.

It is known that the scale structure is flat and the value is limited by the sound quality of 201116075 P51980017TW3l772twf.d〇c/n. The machine pure electrostatic speaker 11 mesh material market is mainly for the view (Hi_end) ear 11 y, the traditional electrostatic speaker is based on the principle of fixed electrode holding Murray twisted # # 疋 liver two pieces of open, 厌,,, Electron into a capacitor, by supplying the diaphragm straight 2B 1 and giving the AC voltage of the two fixed electrode audio, using the positive bin ===== to drive the vibrating diaphragm of the conductive diaphragm and igniting the sound out of the I (four) ΐ electrostatic EMF The pressure needs to be hundreds to thousands of volts, and it is necessary to expand the size of the machine and the size of the magic machine, so it cannot be popularized. Acoustic 11 is made in a way that is designed to produce a single-unit, and is produced in the form of a patent, such as U.S. Patent No. 3,894,199. Regarding the electrostatic type H', as in the US Patent No. 3,894,199, it is mainly disclosed that the structure of the electro-acoustic turn (Eleetn) a_tie t_d_) is as shown in Fig. 1, including the fixed electrodes (7) placed on both sides. ) 11〇 and 12〇. The fixed electrodes 11A and 12A have a plurality of openings for distributing the sound generated. The diaphragm (Vibfatingmm) 13〇 is disposed between the fixed electrodes 110 and 12〇. The fixed structure 14A is made of an insulating material and is used to fix the fixed electrodes 110, 12A and the diaphragm 130. The fixed electrodes 11〇 and 12〇 are respectively connected to a parent voltage source 16 via the transformer 15〇<5. When the alternating current signal is transmitted to the fixed electrode and 120, the potential will be alternately changed to cause the diaphragm 13 to be subjected to both sides. The difference in potential produces a shock, which produces a corresponding sound. However, the above configuration requires enhanced sound pressure output, so that extra power components are required to be driven together, so that the device is bulky and uses more components: the cost is also higher. In addition, since the fixed structure 14A must fix the fixed electrodes 110160, 120, 120 and the diaphragm 130, such an electroacoustic conversion test structure cannot achieve the flexible characteristics. In addition, the traditional technology needs to complete individual monomers one by one in mass production, and the sound has basically a fixed size or shape limitation, so no, effective mass production and cost reduction, and can not achieve soft = thin in appearance Low drive voltage and flexibility. Φ [Summary of the Invention] In an embodiment, a sounder structure is provided. The speaker structure has the characteristics of softness, thinness, low driving voltage and flexibility, and includes a diaphragm, a perforated electrode having a base with an opening, a frame support for fixing the diaphragm and the base on the corresponding sides, And at least one set of supports disposed on the substrate and between the substrate and the diaphragm. Wherein, each set of support body may be composed of at least two strip-shaped elements, and the area between the strip-shaped elements of the same set of support bodies does not overlap with the openings; or each set of support bodies may be composed of a miscellaneous 70 The member is formed of at least one strip-like member, and the region between the point-like member and the strip-like member is not overlapped with the opening. Through the above-mentioned arrangement of the substrate and the support, the material can be saved: the material can be easily cured when the support is produced by the printing method, and the process of bonding and bonding on the support can be easily performed. The difficulty of the process of the upper glue further enhances the sound quality of the sound state. In order to make the above features and advantages of the present invention more comprehensible, the detailed description of the present invention will be described in detail with reference to the accompanying drawings. 201116075 P51980017TW 31772twf.doc/n [Embodiment] According to an embodiment of the present invention, a speaker device may include a substrate, a diaphragm located above the substrate, an electrode above the diaphragm, a plurality of first supports, and a plurality of second Support body. In particular, the first or higher chamber is enclosed between the electrode and the diaphragm, and the second or lower chamber is enclosed between the diaphragm and the substrate. The first support body is provided in the space of the higher chamber and the second support body is provided in the space of the lower chamber, which may be referred to as a sound chamber. In some embodiments, the support can have a different configuration pattern or orientation' which can vary depending on the application or specification. The chamber chamber can be placed in a space corresponding to the speaker's S〇niferous hole area, that is, a higher chamber, and the position of the first support and the position of the second support can be It is symmetrical. In various embodiments, the number of first supports may be greater than, equal to, the number of bites being less than the number of second supports. In some embodiments, the sound chamber structure of a 'flat-type electrostatic speaker can be manufactured by a process of integrating existing manufacturing of a planar electrostatic speaker, and thus, mass production. When the diaphragm is excited by an external voltage, the planar electrostatic speaker can operate according to the surface of the diaphragm according to the charge characteristics of the diaphragm material and the electrostatic force. The deformation of the diaphragm drives the air surrounding the diaphragm to produce a sound. The force applied to the vibration = can be derived or estimated according to the electrostatic force formula and the energy law. For example, the force can be the entire sounding field, the electric field of the part, and the input voltage. Generally speaking, the force applied to the diaphragm/large inside 201116075 P51980017TW 31772twf.doc/n The sound output becomes larger. The electrostatic speaker can be designed to be light, thin and/or flexible. In some embodiments, a sound chamber structure having light, thin, and/or distorted features can be placed in a space opposite the sound hole area of the speaker. The sound chamber structure can include a plurality of suitable supports on the substrate, which can be the second building. The chamber support and the support may be fabricated separately or formed on the substrate or diaphragm electrode. The support can be placed over the electrode, substrate or diaphragm with or without an adhesive. These chamber supports can also be fabricated in advance and then placed between the diaphragm and the substrate. The layout of the body can vary depending on one or more design considerations, such as the electrostatic effect of the diaphragm, its frequency response, and so on. The arrangement of the support may be designed in a different pattern or height depending on the audio characteristics of the support in the plane of the planar electrostatic speaker opposite the support, which may be the first support. In one embodiment, the chamber may comprise a sound absorbing material that enhances the far field effect and/or the Omni-directivity effect of the sound field. In one embodiment, the sound chamber structure design of the planar electrostatic speaker can include a support within the sound chamber space. The design of the support can be adjusted or optimized based on design considerations such as auditory frequency requirements, frequency response, or other auditory or structural factors. The above design changes may include at least a change in the placement and height of the support. For example, the support may have a dot shape, a mesh shape, a cross shape, any other shape, or a combination of two or more shapes. Formulating the design under different design considerations may also include adjusting the distance between any two adjacent supports based on the frequency requirements, frequency response, or other auditory or structural considerations of auditory 201116075 P51980017TW 31772twf.doc/n. Transfer printing, decaling or direct printing such as Inkjet printing or screen printing is applied over the substrate to produce a support. In the other Bega example, the support can be made by direct adhesion. For example, the support can be fabricated in advance, and then the previously produced support is placed between the apertured electrode and the diaphragm or between the substrate and the diaphragm. The support can be placed over the diaphragm, substrate or apertured electrode using a diaphragm, substrate or aperture electrode that is directly or not directly adhered to the underlying membrane. In other embodiments, the support can be fabricated using Etching, Photolithography, and/or Adhesive-dispensing techniques. Referring to Figure 2, for a diaphragm 210 positioned between any two adjacent supports, the speaker 200 can have several working areas. Both sides of the diaphragm 21 can define or define their working areas in the same manner in different ways. The green sound chamber structure can have two chamber spaces to create a resonant sound field or effect of the speaker' one of which is above the diaphragm 210 and below one of the diaphragms. The speaker 200 can have a plurality of supports that can be designed to have a particular shape and placed within the upper and lower chamber spaces. In one embodiment, the higher chamber space of Figure 2 can be a sound hole area, and the lower chamber space of Figure 2 opposite the sound hole area can be a sound chamber structure 272. The space of the lower chamber between the substrate 260 and the diaphragm 210 can be produced by the plurality of diaphragm working areas between any two adjacent chamber supports 201116075 P51980017TW 31772twf.doc/n Resonate the sound field. The speaker unit 200 may include a diaphragm 210, a perforated electrode 220, a frame supporting member 230, and a plurality of subscripts 240 positioned between the electrode 220 and the diaphragm 210. On the side of the diaphragm 210 opposite the electrode layer 220, there is a sound chamber structure 272 which is surrounded or partially surrounded by the substrate 260 and a plurality of supports 270 located between the diaphragm 210 and the substrate 260. The substrate 260, the support 270, and the chamber structure φ 272 it surrounds are selective 'that is, the speaker structure may not include the substrate 260, the support 270, and the sound chamber structure 272 enclosed thereby. The diaphragm 21A may include a body layer 212 and a metal film electrode 214. In some embodiments, the upper surface 212a of the electret layer 212 can electrically couple the frame support 230 and the support 240, and the lower surface 212b of the electret layer 212 can electrically couple the metal thin film electrode 214 described above. The insulating layer 216 can be sandwiched between the electret layer 212 and the electrode 214. The aperture electrode 220 may be composed of metal. In one embodiment, the aperture electrode 22 can also be formed on the paper or non-conductive material by, for example, paper or an extremely thin, non-lubricated material. "When the aperture electrode 220 is composed of a layer of non-conductive material coated with a metal film layer, the non-conductive material may be plastic, rubber, paper, non-conductive cloth (cotton fiber or polymer fiber) or other Non-conductive material; and the metal film may be aluminum, gold, silver, copper, nickel/gold bimetal, indium tin oxide (IT0), indium zinc oxide (], ndium zinc oxide; IZO), Macromolecular conductive material polydioxyethylene thiophene 201116075 P51980017TW 31772twf.doc/n (Polyethylenedioxythiophene; PEDOX), etc., human or any combination of listed materials or their equivalent materials. When 220 uses conductive materials, this The conductive material may be ^ = copper = or its alloy conductive cloth (metal fiber, oxide gold 、, stone fiber or graphite fiber), etc., or any combination of these materials or other materials. Treated or charged to retain static charge for a period of time or an extended time interval, and have a resident or electrostatic effect in the material after charging. The electret layer m can have There are one or more dielectric layers. Examples of dielectric materials include Fluorinated hylene propylene (FEp), Polytetrafluoroethylene (PTFE), Polyvinylidene fluoride (PVDF), and fluorine polymerization. Materials or other suitable materials. The above dielectric materials may include holes having a micron or nanometer diameter. Because the electret layer 212 can retain static charge for an extended time interval and can be subjected to charging treatment It has piezoelectric properties, so holes in the diaphragm enhance transmission and enhance the piezoelectric properties of the material. In one embodiment, bipolar charges can be generated after corona charging (Dipolar) Charges) and remain in the dielectric material to create a resident or electrostatic effect. To provide good tension and/or vibration effects of the diaphragm 210, the metal film electrode 214 can be a very thin metal film electrode. The thickness may be between 0.2 microns and 8 microns or between 2 microns and 0.4 microns. In some embodiments it may be approximately 0.3 μm. The scale shown is 201116075 P51980017TW 31772twf.d〇c/n The range is usually considered to be “ultra-thin”. Taking the electret layer 212 having a negative charge as an example, when an input sound is supplied and the signal is applied to the aperture electrode 22 and the metal thin film electrode 214 having the holes, the positive voltage of the input signal can attract the negative charge of the diaphragm. And the negative voltage of the input signal can generate a repulsive force to the negative charge of the unit, thereby causing the diaphragm 210 to move in one direction. In contrast, when the voltage phase of the input sound source signal changes, 'the same positive voltage can generate a suction force on the negative charge of the diaphragm, and the negative voltage can generate a repulsive force to the negative charge of the unit, thus causing the diaphragm 210 to be in the previous stage. The direction moves in the opposite direction. The diaphragm repeatedly moves back and forth and vibrates to compress the surrounding air to produce sound through interaction of different forces in different directions. In one embodiment, the film 250 may cover one or both sides of the speaker unit 20''. Film 250 may be breathable but water resistant, such as a G0RE-TEX® film comprising Expanded polytetrafluoroethyiene (ePTFE) or the like. Gore-TEX® or similar materials prevent the effects of water and oxygen, thus avoiding the electret layer 212 _ losing its charge and reducing its electrification effect. A plurality of working areas of the diaphragm 210 may be formed between any two adjacent supports 240 and between the aperture electrodes 220 and the diaphragm 21A. These working areas of the higher chamber 242 can be used to produce a resonance sound % of the speaker 2 。. A plurality of working areas of the diaphragm 210 may be formed between any two adjacent supports 270 and between the substrate 260 and the diaphragm 210. These working areas of the lower chamber 272 can also be used to create a resonant sound field of the speaker 2〇〇. The position, height and shape of the chamber of both the support body 240 and the support body 270 can be adjusted. 11 201116075 P519800l7TW31772twf.doc/n As part of the design of the sound state. In addition, the number of the support bodies 27〇 may be greater than or less than the number of the support bodies 240, and the support body 240 or the support body 270 may be directly fabricated on or above the aperture electrode 220 or the substrate 260. The surface of the metal film electrode 214 of the film 210 can be designed by considering the audio characteristics of the speaker or other hearing or structure. The sound chamber may include a sound absorbing material; and the support body or the sound chamber body may be designed in various shapes. The chamber space formed by the frame support body 23 has a sound hole in the frame support body to release the pressure generated by the sonar, and in some cases, produces a better sound field effect. In order to improve the sound quality of the above-mentioned speaker low frequency response, the height of the body can be improved. However, in the process of using printing technology to improve the support == process, as the height of the support increases, in addition to the difficulty in printing the plastic, the curing of the rubber will also increase the support. _ flat speaker.
