The following problem: the side wall end of the yoke can only be manufactured in a one-line structure, and thus the characteristics of the magnetic circuit are degraded. [New content] The purpose of this creation is to solve the above problems. The purpose of the present invention is to provide a yoke for a speaker which is formed at the end of the side wall of the yoke to form a protrusion, or a yoke. The metal ring is joined to enable a high density and uniform magnetic field to be obtained in the gap. Another object of the present invention is to provide a speaker which enhances its characteristics by using a yoke of improved structure. In order to achieve the above object, the yoke of the present invention is constituted by a U-shaped yoke body formed by inwardly forming a side edge of the flat edge of the flat plate and a metal ring joined to the inner side of the side wall of the main body of the body so as to be able to be between the board and the vehicle. A magnetic force is formed in the formed magnetic circuit and is uniform. 1 - The mind is confused. The speaker of this creation includes: a vibrating plate that generates sound through vibration; a voice coil attached to the vibrating plate, and located in the magnetic circuit, vibrating the vibrating plate when the current is secret a frame that supports the vibrating body and which is placed at the inner side of the frame of the _ mu mu ς frame, and is mounted in the production room, where the metal is joined to the inside of the end portion of the side wall: a central portion of the yoke; and a plate attached to the magnet to form a magnetic circuit with the yoke through the gap. Forming the sound 11 of the original $, at the end of the (four) side wall, forming a stop projection on the inner side of the inner side of the stop L, so that the metal ring is mounted on the yoke = -3⁄45 to force the insertion or welding The metal ring is connected to the gap of the pre-shaped side wall of the yoke to obtain a high density and uniform magnetic force, and can be formed by the plate and the wheel. [Embodiment], a preferred embodiment of the present invention is The steps clearly explain the creation of this M384484 and the technical issues solved according to this creation. The following examples are merely illustrative of the present invention and are not intended to limit the scope of the present invention. The second figure is an interlocking perspective view using the yoke speaker of the present invention, and the third figure is a diagram for explaining the action of the yoke of the present invention. As shown in the second and third figures, the 14 〇 of the present invention is formed with a stopper projection 14〇a on the inner side of the U-shaped side wall end, and a metal ring 142 is mounted on the stopper projection 140a, or The metal ring' is joined by forced insertion or welding so that a high density and uniform magnetic force can be obtained. As shown in the second figure, the speaker of the yoke 140 using the present invention is composed of a vibrating plate 11'' which is acoustically transmitted through vibration; a voice coil 120 attached to the vibrating plate no and located at the magnetic circuit The vibrating plate no vibrates when the current flows; the frame 130' supports the vibrating plate n; the vehicle 14 is mounted in the mounting space inside the frame 130 at the stop projection 140a at the end of the side wall A metal ring 142 is attached or weldedly joined; a magnet 150 attached to the center of the vehicle 140; a plate 16A; and a cover 17〇 that engages the frame 13 to protect the internal components. Here, the metal ring 142 is formed to protrude from the vehicle 14 , and is a circular ring or a rectangular ring having a width larger than the width of the plate 160. As shown in the second and third figures, in the speaker 1 of the present invention, the edge of the vibrating plate 11 is supported by the frame 130, and the voice coil 120 is attached to the bottom surface of the vibrating plate 11A. A u-shaped yoke 140' is attached to the inner space of the frame 130. A magnet 15A and a plate 16'' are attached to the central portion of the yoke to form a magnetic path between the plate 160 and the yoke 14'. At this time, according to this creation, at. A stopper projection 140a is formed on the inner side of the side end of the side wall of the yoke, so that the metal ring 142 is attached or joined to the stopper projection 14 〇 & 5 M384484 by forced insertion or welding so as to be able to be slid by the yoke A high density and uniform magnetic force is obtained in the magnetic circuit formed with the plate 160. Also, as shown in the third figure, the metal ring 142 may protrude more than the yoke 140 and be wider than the width of the plate 16'. The following describes the operation of the speaker constituting the present creation as described above. First, as shown in the second figure, the speaker of the present creation forms a magnetic path from the plate 16 to the yoke 14 through a gap (Gap) between the yoke 140 and the plate 160, and is attached to the vibrating plate 11 in the gap. The voice coil of the cymbal is 12 years old. In this case, when an electric signal is applied to the voice coil 120, an electric field is formed by a current flowing in the voice coil 120 between the magnetic paths, and the diaphragm 11 is vibrated to generate a sound. Further, according to the speaker of the present invention, the metal ring 142 is attached to the stopper projection 140a on the inner side of the inline end portion of the yoke 14〇 or is forcibly inserted or welded, so that the panel 16 can be A high density and uniform magnetic force is obtained in the gap (Gap) formed by the yoke 14 . Further, as shown in Fig. 4, according to the yoke 14 of the present invention, the protrusion 142 can be integrally formed on the inner side of the side wall end of the yoke 14 without using a separate metal ring. The present invention has been described above with reference to the embodiments shown in the drawings, but it should be understood by those skilled in the art that the present invention can be variously modified and equivalent embodiments. [Simple description of the drawing] The first figure is a schematic view showing the existing speaker. The second figure is an interlocking perspective view using the present yoke speaker.
