It relates to a speaker characterized by using one component. Conventionally, as shown in FIG. 1, this kind of spi or 'ioj :;-. The vibrating part is the coil (1), the damper (2), the lead wires (4), 2 (4) ', and the cone (4 yo yo corn cone suspension (9) ,! り。 It is composed of -C. The damper (2) is a sleeve-like base material formed by applying electric current, impregnating a resin into a cloth and pressing # 7Jl so as to grow concentric folds, and the inner circular end portion is insulated by winding a coil 4- The end of the outer circle connected to the upper end of the bobbin is fixed to the frame (d) to hold the coil (1). Further, the top of a cone (3) made of a special paper diaphragm is connected and fixed to the upper end of the coil, and the cone (the cocoon is fixed to the frame by a cone suspension (9)). The electrical input is led to the coil (1) from the external terminals (8), (By the lead (in season, (4) 'from the lead wire); Ilk (1) is a magnet (ω and km (6),! The electric input placed in the magnetic field formed by 、 and introduced to the coil (1) is converted to acoustic tremor. This vibration is properly (= propagated and amplified) to the cone (3) by the holding of the damper (2). However, conventionally, as thin line # (4), (4) 'for guiding the electric input to the coil (1), the thin 411! In spite of using 3 soft bales wound with thin copper foil band on a bundle of cotton yarn or thread, lead (4), (4 / end of coil winding at the top of cone (3) Connect one part with the cone and attach a part of the lead 12-05-2019 1 wire directly to the surface of the cone (the attachment is fixed from iso-sini, etc. These give an adverse effect to the above-mentioned cone (the force's proper vibration, Zhou #! I was impressed with the number characteristics. In addition, in the conventional coil winding 4II structure, there is a limit to @ quantification of the speaker displacing portion, and the acoustic characteristics of the speaker are influenced. In order to overcome the above-mentioned drawbacks and to provide superior acoustic characteristics, the coil and the terminal wiring of the coil are formed on the surface of a flexible electrically insulating plastic molding by a printed circuit in order to improve the excellent acoustic characteristics. Enables the lightweight coil of the coil, and at the same time, without using the conventional lead wire, the conductor layer provided on both sides of the damper portion as a coil terminal and one end edge of the damper is fixed to the frame and simultaneously connected to the external terminal As a result, the cone's appropriate vibration t is inhibited. It is intended to improve the speaker's circumferential mantissa characteristic 4 by removing self-conditions. That is, the present invention has four layers on the entire surface except the end of the damper part in a soft, electrically insulating plastic molded body having concentric folds, one consisting of the damper part and the cylinder f part. The present invention relates to a speaker which is provided with a conductive layer such as a conductive layer facing the outer periphery of a round collar portion and a solenoid pattern (== print coil formed by ==). As a flexible electrically insulating plastic molding in the present invention, cloth-Eboxy airi I! 布 Cloth-7 enol rosin, paper-eboki $ '1il &, 祇-pheno, a small thickness of a flexible electric insulating sheet molding such as resin laminate, or an electric insulating film such as varnish, polyolefin, fluorine-based rosin, etc. These are used by heating and molding into a molded body comprising concentric dampers as shown at 3C; and a circular damper portion and a circular tube portion. In addition, as the conductor layer portion on the surface of the electrically insulating def-tick molded body 4, as the d, a PIi film such as steel 5 or aluminum is made to be electrically charged by true wall deposition or plating, or by application such as silver mirror reaction! And the like are preferably used. Apply coating, drying and solidifying photoresist on these conductor layers, and C, forming a mask layer with the desired original pattern on the photoresist surface by the method of 31aT5, consisting of coil and terminal area The desired circuit is one lint to form a single lint coil and a conductor layer (b), d. That is, the abovementioned mask layer is exposed to actinic light 2 from the upper side, the mask layer is removed, a developer is used to develop a predetermined relief image by the photoresist layer, and a conductor layer of a portion not blurred by the photoresist layer Is removed by etching with an etching solution. In this case, the conductor layer (b) and d are initially provided on the entire surface of the molded body except for the damper end edge (2) of the electrically insulating plastic molded body shaft, and the conductor 1mQ4 under the damper portion Is connected to the external terminal-attached to the frame (2) by means of a hammer 6 or the like, and the conductor layer α of the first line is connected to the external terminal by soldering or the like. One end of the tamper may be adhesively fixed via the adhesive layer (b). The electrical 12-05-2019 2 input is led from the external terminal (7) through the conductor layer to the printed coil (b) printed on the outer peripheral surface of the cylindrical tube portion, and C: from the coil (b) to the inner peripheral surface of the cylindrical tube And the upper conductor layer of a part of the damper lead to the external terminal. The following is a more detailed description of the uninvented case according to one reason. FIG. 3 shows the electrically insulating plastic cage (2) and the printed coil (2) which constitute the vibrating portion of the speaker according to the present invention of FIG. It is an expanded sectional view showing the conductor layer (ii), 041 ', external terminal (good), QI 9', and the top of a cone (3). Thickness 0.5 m-2. Ome degree soft, electric insulating plastic molding (2) (2 in (2), in the second part of the die bar, the thickness is made of a copper coating on the entire surface except for the part (2)) Conductor layer α 、 of about 10μ to 50μ ((14 'is formed by the conventional black plating method, and a photoresist material (eg, 7 parts of KFR Kodak) is applied thereon to a thickness of 1μm to 5μ) Dry, print a solenoid pattern with a conductor width of 1.0 麿 and a pitch interval of about 1.5111 on the cylindrical tube part of the conductor layer, print coil (2) and the print coil and external terminals (2), (2) Forming a circuit consisting of the connection with the conductor, ie, the conductor layer (2), u, to produce a speaker part. In order to use this speaker component as the second component, as the vibration component of the speaker, the top of the cone (3) is applied to the circumference @ + of the cylindrical tube of the molded body (2) Through the conductor of the damper (at one end of the damper) in the vicinity of the place where the frame external terminal (至),-'is provided, or through the electrically insulating adhesive layer The construction is fixed only through the adhesive layer (ii), and the conductor layers (2) and (ii) 'are directly connected to the external terminals (d) and d. Mataframe Q (where 1 は 2 is fixed at the bottom of the cone (3) by means of a cone suspension (9)). In the present invention (in FIG. 2, the cone (3) as shown in FIG. 2) is one end edge (2) of the damper (9) and the flexible electrically insulating plastic molding (d) The frame is shredded (: fixedly supported, and the lead wire is not fixed to the cone (3) as in the prior art, and does not prevent proper vibration of the cone as compared with the conventional case. Also, conventionally, enamel coated steel 4I is wound around electrically insulating cylindrical tube in a transverse wave manner, coil increase is stopped by holding agent, and it is attached to a cone (terminal fitting attached near the verge) On the other hand, a conductor layer (b) provided on the surface of a flexible electrically insulating plastic molding (b) consisting of a damper-like damper portion and a cylindrical tube portion according to the present invention; It is connected continuously with the printed coil formed by the pattern, and it is possible to eliminate the location of the conventional copper wire attachment at all. Also, instead of the conventional enameled copper wire winding, by using a printed steel plating layer C, the weight of the film can be reduced, and the entire vibration portion of the speaker can also be reduced in weight. As a result, the present invention can improve the nine vibration 12-05-2019 3 characteristics of the vibration portion of the speaker, and can reliably obtain a speaker having excellent frequency characteristics and C2 excellent acoustic characteristics. 12-05-2019 4
