Form the positioning part to fix the voice coil; D, combined into a speaker. [Prior Art] φ Press, there is a cylindrical electromagnetic shock absorber in the speaker currently used, but because of its large size, it causes various kinds of use, so it is like the Republic of China New Bulletin No. 538647 "Pielet shock absorber" 'patent case, as shown in the fifth figure, is provided with a shock plate (A) which is glued or drawn on a printed circuit board for several times. In the circuit, etc., a voice coil (A1) is fixed, and a top plate (A2)' is provided at the top end of the shock plate (A) for bonding with the surface of the excitation film, and on the two sides of the shock plate (A). Extending out a square column cantilever comprising a φ upper cantilever (A3) and a lower cantilever (A4), the other ends of the upper cantilever (A3) and the lower cantilever (A4) being connected to a fixed seat ( A5), a magnet (not shown) is provided on the front and rear sides of the shock plate (A), and when the voice coil (丨) is energized, an excitation action is generated with the magnet 'to make the shock plate (A) or more cantilever (eight 3) and the lower cantilever (eight 4) can be used as a support to vibrate up and down, and The excitation film is raised to generate a flexible vibration, but since the voice coil is fixed to the shock plate (A) by gluing or the like, the manufacturing is time-consuming, the strength after bonding is weak, and the long-term vibration is easy to use. The shock plate (B) is separated and separated, resulting in poor quality and reliability. 1339079 [Description of the Invention] In view of the fact that the conventional planar speaker is time-consuming to manufacture, the voice coil and the vibration strength of the vibration plate are insufficient, and the quality and reliability are not good, the present invention provides a plane with a sheet-shaped shock absorber. The speaker manufacturing method is that the first A. first produces a planar voice coil: a planar voice coil is formed by a winding method; the ring is placed in a forming mold: the voice coil is placed and fixed to the shock plate to form a forming cooker; c • Forming the positioning part to fix the voice coil: then inserting the voice coil and the excitation plate together, so that the voice coil is surrounded and fixed and integrally formed into a clamping part, D. is combined into a speaker: finally, the vibration plate and the speaker are excited. Film bonding. The upper part of the upper side of the shock plate is provided with an upper cantilever, and the lower side is provided with a lower cantilever, and the other ends of the upper cantilever and the lower cantilever are connected to the fixed seat. In the above step D, the cantilever on both sides of the shock plate can be removed. The present invention has the following advantages: 1. The manufacturing method of the present invention is easy and rapid, and is particularly suitable for mass production, so that the manufacturing cost can be greatly reduced. The invention is formed around the voice coil on the shock plate by injection molding with a positioning 4' to surround and fix the voice coil, so that the voice coil is tightly fixed on the shock plate. After long-term vibration, it will not fall off arbitrarily, and the fixing can be increased. strength. 3. The present invention utilizes (4) the slinger to pinch the voice coil so that the voice coil is formed after the shot is formed, and the heat-dissipating area of the plane voice coil is hollowed out before and after the shock plate. VIII 4. After the shock plate of the present invention is combined with the vibration of the speaker, the benefit is 1339079: used. The two sides of the sea-vibration membrane support the it and the knot respectively. If the sides of the shock plate are cut and removed, there will be a large vibration expansion space, which can reduce the rigidity of the upper and lower vibration directions. The board is more susceptible to vibration, and it is known to have a large sound pressure value to give a better sound quality. [Embodiment] First, referring to the first figure and the second figure, the method of the present invention includes: φ A. First, a planar voice coil is produced: it is first made by a winding method using a winding device to form a square shape. Flat voice coil (2). B. The voice coil is placed in the forming mold: the wound voice coil (2) is placed and positioned in the injection molding die (B) of the shock plate (1) so that its positioning does not move. C. Forming the positioning part to fix the voice coil: as shown in the third figure, the voice coil (2) and the shock plate (1) are injection-molded together in the injection molding die (B) by injection molding, and the shock plate is formed. (1) The upper voice coil (2) is integrally formed with a positioning lu ° (16), thereby surrounding and fixing the voice coil (2), so that the voice coil (2) is tightly fixed on the shock plate (1). It does not fall off arbitrarily and can increase its fixing strength. The shock plate (1) is formed in a piece shape, a top plate (11) is arranged at the top end of the shock plate (1), and an upper cantilever (12) is further extended above the two sides of the shock plate (1). The lower cantilever (13) is disposed at the bottom, and the other ends of the upper cantilever (12) and the lower cantilever (13) are connected to the fixed seat (14), wherein the lower cantilever (13) and the fixed seat (14) There is a flexible section (15) of a type [or υ type, upper concave arc type, concave concave type, continuous wavy shape). D. Synthesizing the speaker: As shown in the fourth figure, finally, the formed 1339079 is excited, and the top plate (1) of the plate (1) is combined with the excitation film (3) of the speaker. The excitation diaphragm (3) is surrounded by the periphery and the periphery. The suspension support (31) is connected to form a speaker. If the connection between the speaker and the excitation film (3) is made into a suspension support (31) with rear, left and right symmetry and rigidity in the up and down direction, the cantilever (12) on both sides of the shock plate (1) is cut. Drop removal, also 'can be combined into another speaker constructor. The cantilever (12) on both sides of the shock plate (1) is cut off and used. It is called to prevent the shock plate by using the suspension symmetrical support (31) in the plane direction around the excitation film (3). The mechanism that swings back and forth and left and right, so when the shock plate (1) generates up and down vibration, it can assist the shock plate (1) to vibrate up and down at a fixed position on the plane to avoid the shock plate (1) swinging back and forth, left and right, and then The cantilever (12) on both sides of the shock plate (1) is cut off to reduce the rigidity of the vibration direction support; and the door type elastic section (15) is arranged between the lower cantilever (13) and the fixed seat (14). Therefore, it has a large vibration expansion space to reduce the rigidity of the upper and lower vibration directions, so that the shock plate (1) can be more easily shocked and a larger sound pressure value is obtained; and the width of the lower cantilever (13) is matched. The flat type surface elastic section (15) can increase the rigidity of the front and rear swing directions, so that the shock plate (1) reduces the amplitude of the front and rear swings, avoids friction with the magnet, and the voice coil (2) is subjected to the positioning portion formed around. (16) Surround and fix to make the voice coil (2) Under long-term vibration, it can still be tightly fixed on the shock plate ο) without arbitrarily falling off.
