New description: ♦ 【New technology field】 This creation is about the kind of sound H, especially related to a thin electrostatic speaker. [First-hand technology] The commonly used speakers are divided into three types: dynamic, piezoelectric (piez〇) and electrostatic. Among them, moving coil speakers are the most widely used, but The portability of the speaker H is not good enough to meet the needs of people (4) light and thin electronic products. Piezoelectric speakers are based on the electric effect that deforms the piezoelectric material to produce sound, but such speakers are not widely used because of their resonance and sound. Electret Green has recently developed a kind of electrostatic speaker. The electret speaker has the advantages of light weight, wide bandwidth and no distortion, and no need for additional bias. Fig. 1 is a view showing the structure of a conventional electrostatic speaker. A conventional electrostatic speaker includes an electret diaphragm u, a conductive layer 12 disposed on the surface of the electret diaphragm u, a package spacer 14 and an electrode 15. The electret diaphragm 11 can hold a charge, and the spacer I4 is disposed between the electrode 15 and the electret diaphragm u, and the (four) pole 15 and the conductive layer 12 are separated from each other by the sealing material 13 for sealing the edges of the above elements. The electret diaphragm u is permeable to the electric field between the conductive layer 12 and the electrode to generate sound, and the sound is transmitted through the miscellaneous isp to release the plurality of side holes 16. In the electrostatic speaker 1 of the above-mentioned %, the conductive layer is directly deposited on the electret diaphragm η. Since the electret body vibration mi is generally a porous structure, the porous structure tends to cause the formation of the conductive layer 12 to be poor, causing the surface of the conductive layer 12 to undulate or even form a fracture structure, so that the problem of poor conductivity is 3 M430769 . Furthermore, since the electret diaphragm 11 itself is expensive, if the electret diaphragm 11 is purchased from the supplier, the conductive layer 12 is plated, and the conductive layer 12 is plated on the electret diaphragm u. If the quality is not good, it cannot be used or even discarded completely, so there is a problem of high production cost. In view of this, how to provide an electrostatic speaker to solve the problem of high cost and poor conductivity caused by plating a conductive layer on the surface of an electrostatic film is a goal that the industry needs to work hard. [New Content] The purpose of this creation is to provide a thin electrostatic speaker that solves the problem of the high cost and poor conductivity of the conventional conductive layer recorded on the surface of the electrostatic film. According to the foregoing purpose, the present invention provides a thin electrostatic speaker comprising: - an electrode; - an electrostatic film "a film capable of retaining an electrostatic charge for a long period of time; a spacer material disposed between the electrode and the electrostatic film" The electrode and the electrostatic film; and a polymer film having a first surface and a first surface, the first surface is provided with a conductive layer, and the second surface is in direct contact with the electrostatic film. The present invention further provides a thin electrostatic speaker comprising: - a first electrode and an electric and a first electrostatic film, and a second electrostatic film, the first electrostatic film and the second electrostatic cymbal long listening to an electrostatic film; a first spacer disposed between the first electrode and the first electrostatic discharge to separate the first electrode from the first electrostatic film; - the second interval ^, the second t first and the second Between the static faces, the second electrode and the second film are separated; and - the first polymer film and the second polymer layer, the first polymer is thin (four), a first surface and a first surface 1. The first surface of the first surface is plated with a first conductive layer, and the second surface of the M430769 is in direct contact with the first electrostatic film. The second polymer film has a third surface and a fourth surface. The third surface is provided with a second conductive layer, and the fourth surface is in direct contact with the second electrostatic film. The present invention is characterized by a conductive layer on the surface of the polymer, due to the polymer film. The cost is low, if the quality of the plated conductive layer is not good, it can be disposed of immediately, and the surface of the polymer film is flat. It does not affect the formation of the conductive layer. Therefore, the present invention can solve the problem of high cost and poor conductivity caused by the conventional bonding of the conductive layer to the surface of the electrostatic film. [Embodiment] The technical content and structure of the present invention will be described in detail. The purpose of the smear, the purpose and the effect are as follows, and the drawings are explained in detail with reference to the drawings. Fig. 2A is a schematic view showing the assembly of the thin electrostatic speaker of the first embodiment of the present invention, and Fig. 2B is a view showing the thin type of the first embodiment of the present invention. A schematic diagram of the assembly of the electrostatic speaker is completed. As shown in FIG. 2 and FIG. 2B, the thin electrostatic speaker 2 of the first embodiment of the present invention comprises an electrode 25, an electrostatic film 2, a spacer 24, and a polymer film. 2〇 and the conductive layer 22 disposed on the surface of the polymer film 2〇.

Referring to Fig. 3A, the thin electrostatic speaker 3 of the second embodiment of the present invention can be produced by the following method. The first molecular film 31 and the second polymer film 32 are provided, and the first conductive layer 32 is deposited on the first surface of the first polymer film 31, and the third polymer film 32 is disposed on the third surface.

In the prior art, the conductive layer is directly plated on the electrostatic film. Since the electrostatic film is relatively expensive, if the conductive layer provided on the electrostatic chip is of poor quality, it cannot be used or even completely discarded. Moreover, the aperture structure of the electrostatic film is caused to cause the surface of the conductive layer to undulate during the recording, and even to form a broken matrix, which leads to miscellaneous. In this creation, the conductive layer is touched on the surface of the polymer film. Since the cost of the polymer film is low, if the quality of the conductive layer of the mine is not good, it can be disposed of immediately, and the Xiezi fine table is supplemented, and the conductive material is formed. This creation can solve the problem of high cost and poor navigation caused by the electrostatic film watch riding. Figure 4 is a graph showing the sound pressure and frequency of a thin electrostatic speaker implemented in accordance with the present creation. It can be seen from Fig. 4 that the sound electrostatic performance of the thin electrostatic speaker of the present invention is quite stable in various frequency ranges, and there is no _ job or special _ in the other, which means that the thin electrostatic speaker H of the creation is followed by Wei __ Paste (10), from the actual data shown in Figure 4, it can be seen that the sound performance of the thin electrostatic speaker made directly from the surface transfer layer is the same. In the present creation, the area of the original first electrode 251 and the second electrode can be reduced, and 9 M430769 makes the area occupied by the first pole 251 smaller than the area occupied by the first spacer 23, and the area occupied by the second electrode is smaller than the first The area occupied by the two spacers 23. As shown in Fig. 5, the upper, lower, left, and right sides of the first electrode 251 are each predetermined distance based on the side of the first spacer member 23, for example, two faces 'e.g., the length (1) of the first-electrostatic film 211) The width (W1) is different from the length (10) and the width (W2) of the first spacer 23, and when the size of the first spacer 23 is _24 _2 (ie, L2 = 164, W2424), the size of the first electrode 251 It is 16〇χΐ2〇 ugly 2 (ie L3=i6〇, W3=12〇). Similarly, the upper, lower, left, and right sides of the second electrode 252 are inwardly contracted by a predetermined distance according to the side of the second spacer 23, for example, two positions, for example, the length and width of the second electrostatic film are respectively The length and width of the second spacer 23, and the size of the second spacer 23 are 2, and the size of the two electrodes 252 is 16 〇χ 12 〇 2 . With the above configuration, it is possible to prevent the sides of the first electrode 251 and the second electrode 252 from coming into contact with each other, so that the problem of short-circuiting of the electrode burrs can be improved, thereby improving the sound performance and improving the yield of the product. In an embodiment, as shown in FIG. 6, the thin electrostatic speaker further includes a first electrode ear 61 and a second electrode ear 62.

In order to speed up the speed of the wire to the electrode ear, the present invention adopts a configuration in which the distance between the first electrode ear 61 and the second electrode ear 62 is short. The preferred configuration is: the first hole of the first electrode ear 61 The ratio of the distance between the 61 〇 and the second hole of the second electrode ear 62 to the side length of the side where the first electrode 61 and the second electrode ear 62 are located is between five and two. For example, 'assuming that the size of the first electrode (5) and the second electrode Μ2 is chest 2 即 a (ie, L-160 'W=12 〇), the first electrode ear 61 and the second electrode ear are located in the corresponding On the side in the width direction, the first hole (10) of the first electrode ear 61 and the second hole of the second electrode ear are preferably 35 Å. Thus, since the distance between the first hole and the second hole 62〇 is relatively close, when the wire is riveted to the electrode ear using the riveting machine, the two wires can be riveted at one time, greatly improving the speed of riveting. Therefore, it can improve production efficiency. On the other hand, since the distance between the first hole 61〇 and the second hole 62〇 is shortened, the length of the wire can be reduced as compared with the original design, which can greatly reduce the cost of wire use in mass production. .
