Description

1255148 IX. Description of the Invention: [Technical Field of the Invention] A vibration system of a flat speaker, in particular, a sound film of a Ribbon Type Planar Speaker and a method of manufacturing the same. [Prior Art] The use and development of ribbon-type flat-panel speakers have been well-known, such as the patents of Jue 4273968, 4480155, 6104825, 4471173, and 5021613, revealing the structure and related content of the ribbon-type flat speaker. Generally, the crucible of the ribbon type flat speaker is as shown in Fig. i. The metal conductor 14 is directly on the insulating thin crucible 15 to form a sound film having an electric circuit. When the sound is emitted, the current signal is passed. The electric current through the electric circuit generates an electromagnetic force with the magnetic field of the magnet 11 on the ribbon type flat speaker, so that the sound film vibrates, and the sound is transmitted through the sound film to promote the sound of the air, thereby converting the electric energy into sound energy. Different from the general moving-coil loudspeaker, the electrical circuit on the sound film of the ribbon-type Pingnan speaker itself, that is, the function of the voice coil, can drive the vibration of the sound film, and the two general moving coil speakers The membrane needs to be connected to the voice coil (VoiceCoil), and the voice coil is vibrated to drive the sound of the sound film. Since the ribbon type flat speaker has a thin film and a light weight, the quality of the vibration system is lighter than that of the general moving picture speaker, so the ribbon type flat speaker has a higher spiritual singer. The magnetic circuit system of the ribbon type flat speaker is also designed in the manner as disclosed in Fig. 2, and the strip magnets 21, 22 which are parallel to the electric line direction are disposed on the upper and lower sides or the side of the sound film. The strip magnets 21, 22' are arranged symmetrically on the upper and lower sides of the sound film to make the magnetic field above and below the sound film uniform and symmetrical, so that there is a large linear dynamic range and high sensitivity. Ribbon-type flat speakers, like moving coil speakers, can be used with the piston 1255148

Hm〇n) way, with the infinite obstacle board (Infinite's condition 'bringing __ unified power m' output audio characteristics. * * Lawrence E. Kinsier i^, ^rentals〇of -t ^ ^ ^ ^ The relative relationship between the far field and the equivalent radius and distance of the Far Field sound dust and the frequency filter is as follows: Sound pressure ρ = (,2 *ττ2 * p〇* a2 * / r ί ^ For the drunk, PQ is the air density, a is the radius of the county sound film piston, and f is the vibration frequency, !: the amplitude of the piston for the sound film, r is the distance between the test point and the speaker. Under the same sound film area and the same test distance 卞, the sound pressure private frequency ^ square and the amplitude - the power of the square is proportional. In order to produce the same sound pressure, at the local frequency, the sound film requires only a small amplitude In contrast, at low frequencies, the sound film has a large amplitude to produce the same sound pressure. Unless the area of the sound film is enlarged, the low-frequency response (Lqw Frequency Response) of the ribbon-type flat speaker is not good. The sound film of the ribbon type flat speaker, one of which is made of aluminum foil and Mylar plastic Or a laminated material of a polyfluorene film (p〇iyifflide) formed by a metal electrode line through an etching process, although the sound can generate a high frequency response, but cannot generate a low frequency response. In addition, there is also a metal wire. Or a sound film formed by Mylar and aluminum foil laminated on a pre-formed flat plastic drum paper or a flat honeycomb structure board (Honeyc〇ne pia cut) or a polystyrene foam board (Styrofoam), and then 贞i The upper suspension forms a composite sound film. Alternatively, the metal wire or the sound film formed by laminating the aluminum film and the aluminum foil is directly embedded in the polystyrene foam board and integrally formed with the hanging edge. Responsive, but the weight is too heavy, the sound pressure is low. SUMMARY OF THE INVENTION The object of the present invention is to provide a ribbon type flat speaker sound film, which has a good balance of low frequency response and sensitivity. Another object of the present invention is to provide a ribbon type flat speaker, which can eliminate the low frequency response of the ribbon type flat speaker; SUMMARY OF THE INVENTION The present invention provides a method for manufacturing a ribbon type flat speaker sound film, comprising the following steps: first providing a composite metal film composed of a metal layer and a high-g insulating layer, and then the metal layer in the composite metal film Etching, the metal layer is formed into a conductor line to form a ribbon g sound film. In addition, an impregnated fiber is used as a planar reinforcing structure, and the wire is placed on one side of the planar reinforcing structure, and A composite sound film having a j-hanging edge is obtained by combining heat. The present invention has a large-amplitude structure due to the presence of a hanging edge, and has a low-frequency response, and a planar reinforcing structure. Formed integrally with the overhang, the method of manufacture is simpler. In addition, the present invention also provides a composite sound film of a ribbon type flat speaker, comprising: a metal layer formed in the shape of a conductor line; and a polymer insulating layer forming a composite metal film with the metal layer. In addition, a planar reinforcing structure formed by impregnating resin fibers and containing a suspension is formed, and the integrally formed planar reinforcing structure is combined with one side of the polymer insulating layer of the composite metal film to form a composite structure. Composite sound film for ribbon flat speakers. Since the present invention is provided with a planar reinforcing structure containing a suspension, it has a good low frequency response, and further, because of the use of impregnated resin fibers to form a planar reinforcing structure, the weight is light and the sensitivity is good. Further advantages of the invention, as well as further details, are further illustrated by the following examples. [Embodiment] 1255148 Please refer to Fig. 3, which is a cross-sectional view showing an embodiment of a ribbon type flat speaker of the present invention. The composite sound film 31 of the speaker includes an upper ribbon type sound film, a planar reinforcing structure 37, and a lower ribbon type sound film. The upper ribbon type sound film is composed of an upper insulating layer 31A and an upper upper insulating layer <metal electrode line 33a. The lower ribbon type sound film is composed of a lower insulating layer 31B and a metal electrode line on the lower side of the lower insulating layer. The planar reinforcing structure 36 further has a hanging edge structure 37. Among them, the upper ribbon type sound film is a double-layer composite metal film of the metal foil/polymer insulating layer 31A, 31B. It is made of a two-layer soft printed circuit board composed of two layers of aluminum having a thickness of 23 mm and a layer of polypyrene (P〇lyimide) having a thickness of 10 μm. Thereafter, ribbon-type sound film guide lines 33A, 33B are produced. In the production of a double-layered composite metal film, a metal foil is first coated with a solution of a polyamic acid (Polyamic Acid) and then baked and dried. However, it is also possible to produce a metal layer by a method of physical vapor deposition and electroless plating on a polyimide film. Since the double-layer composite metal film has no adhesive layer as a buffer layer, the thermal expansion coefficients of the metal layer and the polymer insulating layers 31A and 31B must be as uniform as possible to avoid curling of the composite gold film due to the difference in thermal expansion coefficient. And interlayer stress. Two planar reinforcing structures 36 having a hanging edge structure 37 are made of Nomex temperature-resistant fiber paper (DuPont products, model N〇mex 411) having a thickness of 0·13 mm, and a solid content of 5-20% by weight.
