[New type of technology to the jaw] [0001] This creation is related to / kind of piezoelectric taste 八', especially regarding the use of a piezoelectric fiber sheet. [Prior Art] [0002] At present, a speaker (speaker) is one of the weakest devices in an audio device, and it is one of the most important components for sound effects. There are many types of speakers. According to the conversion mechanism, it can be divided into moving coil type, electrostatic type, and piezoelectric type. [0003] The moving coil type using the magnet and the coil is still the main working mode of the horn, and the magnetic field generated by the current through the coil interacts with the magnetic field of the permanent magnet to generate a force on the coil, which drives the diaphragm to vibrate and sound. The layout and density of the flux density determine the magnitude of the force. Since the low-frequency current can produce the current force, the low-frequency response is best. With the design of the speaker, the dynamic small speaker can achieve a low sound response of about 400 Hz, and the thickness is in the range of several millimeters. In line with the trend of thinning electronic products, the design of moving coil speakers is also becoming thinner, but limited by the fact that the magnetic circuit is not easily concentrated in a thin enough space, resulting in a thinned dynamic horn with nonlinear and low frequency distortion. The problem is to compensate for the lack of low-range, thin-type speaker design has become an auxiliary tool, only in the case of sub-millimeter thickness (ie <1 ram), the dynamic horn has a problem of poor low-frequency response. The dynamic size of the dynamic-style eight is relatively complete, so it is often made into a portable speaker product, as an additional addition of electronic products. Eight, the remaining thickness is generally above the public grade. [0004] Electrostatic ( Or an electret type horn uses an ultra-thin electrostatic film, through the third page / a total of 21 pages form number Α 0101 M429277 plus AC signal to attract or repel the electrostatic film, pushing the diaphragm to produce sound. Due to the electrostatic film It is easy to be affected by humidity and loses electricity. Therefore, the electrostatic repulsion force is reduced. Therefore, it is necessary to have a good humidity to block the package. The static electricity is not affected by the applied electric field, so as not to lose the resident electricity. The electrostatic film must not have excessive displacement. Therefore, there is an insulating sheet for spacing between the electrodes and the insulating sheet, and the insulating sheet reduces the effective area of the diaphragm, resulting in poor electrostatic response at low frequencies. Although the size of the overall electrostatic film can be increased to obtain the low range. Improvement, too large area makes it limited to use in portable electronic products, and is still in addition to La. Eight products are mainly in the form of moving coils. Compared with the flexible characteristics, the total thickness can reach ultra-thinness of about 100 micrometers, and the application of the built-in speaker in electronic products can not be exerted. [0005] Piezoelectric La "Equipped with electromechanical conversion film, driven by external electric field Mechanical deformation, driving the diaphragm to make it sound. Piezoelectric material is a highly rigid ceramic material, the vibration generated by the combination of the diaphragm is not conducive to the performance of the low range, although the low-range response can be improved by the thickness reduction, only limited by the fragile nature of the ceramic. It is not easy to make piezoelectric ceramic sheets with a thin thickness. For example, Murata, which has the ability to make the thinnest 30/zm piezoelectric sheets in the world, has a low range of about 1 kHz. The performance of the low range is still quite improved. Space. The use of multi-layer structure can improve the fragility of ceramic sheets. For example, Murata's multi-layer piezoelectric small-size eight-product product, the sound pressure can also be increased by the superposition of multiple layers, but the improvement of the response of the low-range is still insufficient. [0006] In order to improve the low-range response problem, NXT Corporation uses dis-tributed modeactuator (DMA) to obtain a wide-range flat racquet, its DMA Using the moving coil or piezoelectric type, since the resonant mode is divided into the form number A0101, page 4 / 21 pages, the produced plane la α has a wide frequency domain response characteristic, only to obtain enough low range (< The volume of the 300 Ηζ), the size of the à eight is often tens of centimeters, so it is only suitable for external speaker applications, such as the inability to provide the high-quality sound contained in the electronic products. The demand for eight. [0007] Of course, this case The piezoelectric ceramic fiber used and the longitudinal 1-3 structural composite material have the advantages of easy process and high piezoelectricity. The fiber and composite materials have patent applications, which can strengthen the competitiveness of domestic manufacturers and avoid being restricted by foreign companies. Patent: Using 1-3 structural piezoelectric composite material to reduce the rigidity of the material while maintaining a sufficiently high piezoelectricity, the thin-type η8 produced by the conventional piezoelectric ceramics has better low-frequency characteristics. It has a thinner advantage than the moving coil type Lama. The piezoelectric fiber composite material is a simple structure and thinning type of piezoelectric ceramics, and the low frequency response of the moving coil type is better. The existing system σ eight has more competitive advantages[New Content] [0008] In view of the above-mentioned shortcomings of the prior art, the present invention designs a piezoelectric fiber horn having patents such as novelty, advancement, and industrial utilization, in order to overcome the difficulties of the prior art.

The surface 302 is plated with a second conductive layer 322, and the second conductive layer 322 and the second conductive layer 322 on the second surface 302 are electrically connected to each other, and one end of the first conductive element 42 is connected to the electrode portion 12, and the other end The first conductive layer 321 is disposed on the first conductive layer 321 , and one end of the second conductive element 52 is also connected to the electrode portion 12 , and the other end is disposed on the second conductive layer 322 . As shown in Fig. i, the original second conductive member 50 is connected between the piezoelectric fiber sheet 3 and the thin flag 2〇, which may cause a problem that the bonding of the piezoelectric fiber sheet and the film may not be tight enough. Therefore, as shown in FIG. 3, the first block 331 and the second block 332 are separated by the mask 33 on the first surface 3〇1 insulating region, and the first conductive layer on the second block 332 is formed. 322 is electrically connected to the second conductive layer 322 on the second surface 3〇2, thereby improving the connection position of the second conductive element 52 to avoid the above problem. Just refer to Figure 4, and Figure 4 is the second schematic diagram of the first example of the remaining 8 of the grinding fiber. As shown in the figure, the piezoelectric fiber is different from the foregoing as a film, and the film can be a conductive film 21. Therefore, one end of the first conductive member 43 is still connected to the electrode portion 〖2, and the other end is set at the second end. - Conductive film 311, and the conductive film 21 is used to replace the second conductive element of the M429277 which is originally connected to the electrode portion, Form No. A0101, page 9 / 21 pages, thereby improving the second conductive element on the piezoelectric fiber. Between the sheet and the film, the adhesion of the piezoelectric fiber sheet to the film may not be tight enough. [0023] As shown in FIGS. 5 to 9, a second embodiment of the piezoelectric fiber horn of the present invention is shown. [0024] Please refer to FIG. 5 and FIG. 6 , and FIG. 5 is a piezoelectric fiber of the present invention. A first exploded view of the second embodiment of the eighth embodiment; and a sixth schematic view of the second embodiment of the piezoelectric fiber sigma of the present invention. As shown in FIG. 5, the difference between the embodiment and the first embodiment is that the piezoelectric fiber horn 4 can include a metal damper 60 including a metal outer frame 61, a metal inner frame 62 and a plurality of connecting portions. 63. The connecting portion 63 connects the metal outer frame 61 and the metal inner frame 62, and the metal damper 60 is provided on one surface of the film 20. As shown in Fig. 6, the metal inner frame 62 is spaced apart from the piezoelectric fiber sheet 30 by a space 70, so that the metal inner frame 62 does not come into contact with the peripheral edge of the piezoelectric fiber sheet 30. [0025] Please refer to FIG. 7 to FIG. 9 , and FIG. 7 is a second exploded view of the second embodiment of the piezoelectric fiber Rakou eight of the present invention; FIG. 8 is a piezoelectric fiber of the present invention. "Second schematic diagram of the second embodiment of the eighth; FIG. 9 is the piezoelectric fiber of the present invention. A third schematic diagram of the second embodiment of the eighth embodiment (the dotted line in the figure indicates an element that cannot be displayed by overlapping). As shown in Fig. 7, the piezoelectric fiber horn 5 is different from the above in that the metal damper 60 is provided on the other side of the film 20. As shown in Fig. 8, the metal inner frame 62 corresponds to the position of the piezoelectric fiber sheet 30 via the film 20. As shown in Fig. 9, the metal inner frame 62 may also be spaced apart from the space of the piezoelectric fiber sheet 30 by a space 70 spaced apart from the film 20. [0026] The second embodiment of the present invention is based on the piezoelectric fiber of the second figure, for example, the form number Α0101, the 10th page, the total of 21 pages, and the piezoelectric fiber horns of the third and fourth figures. Metal dampers can also be installed, although not graphically expressed, should not be limited to this. [0027] The foregoing is illustrative only and not limiting. Any equivalent modifications or changes made to the spirit and scope of this creation shall be included in the scope of the appended patent application.
