Description

TECHNICAL FIELD

[0001] The present invention relates to a manufacturing method of a loudspeaker diaphragm, and more particularly, to a manufacturing method of a loudspeaker diaphragm with elastic fatigue. BACKGROUND

[0002] Generally, a moving coil loudspeaker produces sound by using the principle that a magnetic field is moved in the opposite direction by the reaction force of another magnetic field (i.e., opposite poles attract, and like poles repel). In further detail, power alternating current from a power amplifier is transmitted to a voice coil through a wire to change the polarity of a magnetic field, so that the voice coil generates a reaction force with respect to a fixed magnetic field generated by a magnetic gap of a magnetic circuit device. A positive pulse causes a diaphragm to move outward with respect to a magnet, and a negative pulse causes the diaphragm to move inward with respect to the magnet. When the voice coil pushes the diaphragm to move back and forth, the diaphragm pushes air, and the air pressure is changed to form a sound wave. A spider serves to maintain the voice coil in a correct position in a gap of an iron core of the magnet, and to ensure that the voice coil moves back and forth in the axial direction when a force is applied. A suspension is provided between the diaphragm and an outer frame to support the diaphragm.

[0003] Generally, non-metallic parts included in a loudspeaker are made of a base material. The main reason for this is that the base material, which has been treated in a special way, has appropriate elasticity and strength, and can provide the required function when the loudspeaker is operated. For example, the diaphragm, the spider, the suspension, or the drum paper in a small loudspeaker all belong to this category. Such non-metallic parts are collectively referred to as loudspeaker diaphragms. The base material is woven from a plurality of warp yarns and a plurality of weft yarns.

[0004] A conventional manufacturing method of a loudspeaker diaphragm includes the following steps: immersing a base material in a resin solution; drying the base material; heating and pressing a loudspeaker diaphragm forming block on a loudspeaker diaphragm forming area of the base material to form a loudspeaker diaphragm; and separating the loudspeaker diaphragm from the base material.

[0005] However, in the process of heating and pressing to form the loudspeaker diaphragm, the loudspeaker diaphragm forming block is easily excessively shrunk because the loudspeaker diaphragm forming block has elasticity, and thus the formed loudspeaker diaphragm is easily deformed.

[0006] Furthermore, the existing loudspeaker diaphragm manufacturing method is automatically and continuously performed, and the base material has a certain elasticity, so that each flat loudspeaker diaphragm forming block is crimped into a wave-shaped loudspeaker diaphragm in the process of heating and pressing. Because all the loudspeaker diaphragm forming blocks have the same plurality of warp yarns extending through, the crimping force of all the loudspeaker diaphragm forming blocks pulls each subsequent loudspeaker diaphragm forming block to move a distance forward through the warp yarns, so that the positions of the subsequent multiple loudspeaker diaphragm forming blocks are slightly deviated from the original preset positions. In this way, the hot-press forming device forms the loudspeaker diaphragm at the positions of the subsequent multiple loudspeaker diaphragm forming blocks which are slightly deviated, instead of forming the loudspeaker diaphragm completely at the positions of the subsequent multiple loudspeaker diaphragm forming blocks, resulting in that the interval distance of the subsequent multiple loudspeaker diaphragms is larger than the preset interval distance. Since the base material between the adjacent two loudspeaker diaphragms will form waste, the above problem will generate more waste than originally imagined, which is quite a waste.

[0007] In addition, when the loudspeaker diaphragm forming blocks are continuously formed into the loudspeaker diaphragms, the plurality of warp yarns extending through between the loudspeaker diaphragm forming blocks are simultaneously pulled and broken by the crimping forces in different directions, further causing the base material to be torn. SUMMARY

[0008] The main purpose of the present application is to provide a method for manufacturing an elastic fatigue loudspeaker diaphragm, which first elastically fatigues the loudspeaker diaphragm forming block, and then hot-presses the loudspeaker diaphragm thereon, so that the manufactured loudspeaker diaphragm will not be deformed.

[0009] Another purpose of the present application is to provide a method for manufacturing an elastic fatigue loudspeaker diaphragm, which keeps the positions and intervals of the loudspeaker diaphragm forming blocks unchanged, thereby reducing the amount of waste generated.

[0010] Still another purpose of the present application is to provide a method for manufacturing an elastic fatigue loudspeaker diaphragm, which prevents the yarns between the multiple loudspeaker diaphragms from being broken, thereby avoiding the base material from being torn.

[0011] In order to achieve the above purposes, the present application provides a method for manufacturing an elastic fatigue loudspeaker diaphragm, which comprises the following steps: soaking a base material in a resin solution; drying the base material; a plurality of pulling devices respectively pressing around a loudspeaker diaphragm forming block of the base material, and the pulling devices pulling the loudspeaker diaphragm forming block outward in different directions, so that the loudspeaker diaphragm forming block is elastically fatigued; heating and pressing on the loudspeaker diaphragm forming block to form a loudspeaker diaphragm; and separating the loudspeaker diaphragm from the base material.

[0012] In some embodiments, the step of elastic fatigue of the horn diaphragm molding block further includes: the pulling device being a plurality of corner posts, each corner post pressing against a plurality of corners of the horn diaphragm molding block; and two of the corner posts pulling outward in opposite directions two of the diagonally opposite corners of the horn diaphragm molding block, while the other two corner posts pulling outward in opposite directions the other two diagonally opposite corners of the horn diaphragm molding block.

[0013] In some embodiments, the step of elastic fatigue of the horn diaphragm molding block further includes: the pulling device being a plurality of side posts, the side posts respectively pressing against a plurality of sides of the horn diaphragm molding block; and two of the side posts pulling outward in opposite directions two of the opposite sides of the horn diaphragm molding block, and the other two side posts pulling outward in opposite directions the other two opposite sides of the horn diaphragm molding block.

[0014] In some embodiments, the step of elastic fatigue of the horn diaphragm molding block further includes: the pulling device comprising a plurality of corner posts and a plurality of side posts, the corner posts pressing against a plurality of corners of the horn diaphragm molding block, and the side posts pressing against a plurality of sides of the horn diaphragm molding block; and two of the corner posts pulling outward in opposite directions two of the diagonally opposite corners of the horn diaphragm molding block, and the other two corner posts pulling outward in opposite directions two of the diagonally opposite corners of the horn diaphragm molding block, while two of the side posts pulling outward in opposite directions two of the diagonally opposite sides of the horn diaphragm molding block, and the other two side posts pulling outward in opposite directions two of the diagonally opposite sides of the horn diaphragm molding block.

[0015] In some embodiments, prior to immersing the substrate in the resin solution, the following step is further included: forming a slit between two horn diaphragm molding blocks of the substrate, the length of the slit being greater than or equal to the width of the horn diaphragm molding blocks.

[0016] In some embodiments, between the step of immersing the substrate in the resin solution and the step of drying the substrate, the following step is further included: forming a slit between the two horn diaphragm forming blocks of the substrate, the length of the slit being greater than or equal to the width of the horn diaphragm forming blocks.

[0017] In some embodiments, the step between drying the substrate and forming the horn diaphragm further includes the following step: forming a slit between two horn diaphragm forming blocks of the substrate, the length of the slit being greater than or equal to the width of the horn diaphragm forming blocks.

[0018] The advantage of this invention lies in the fact that the method first loosens the yarns of the trumpet diaphragm forming block using the pulling device, causing the forming block to lose its elasticity. Then, heat and pressure are applied to the elastically fatigued forming block to form the trumpet diaphragm. Therefore, all the yarns in the trumpet diaphragm forming block experience equal shrinkage forces, resulting in more uniform shrinkage forces and preventing deformation of the manufactured trumpet diaphragm.

[0019] Furthermore, the method of the present invention forms slits between the horn vibrator forming blocks, which can break the warp yarns extending through the horn vibrator forming blocks. Therefore, during the continuous heating and pressing of the horn vibrator forming blocks to form multiple horn vibrators, the wrinkling force of the previous horn vibrator forming block is limited to the previous horn vibrator forming block and the slit, and will not pull on the yarns between the next horn vibrator forming block and the slit. As a result, the positions of the horn vibrator forming blocks can remain unchanged, and the spacing distance can also remain unchanged, with no deviation problem, reducing waste generation.

[0020] Furthermore, the method of the present invention forms slits between the horn diaphragm forming blocks, which can break the warp yarns extending through the horn diaphragm forming blocks. Therefore, when the next horn diaphragm forming block is heated and pressurized to form the next horn diaphragm, the yarn between the next horn diaphragm and the slit is pulled backward by the wrinkling force, but it will not pull the yarn between the previous horn diaphragm and the slit, so the yarn between the horn diaphragms will not be torn, thus avoiding the substrate from being torn.

[0059] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and component symbols, so that those skilled in the art can implement them after studying this specification.

[0060] Figure 1 This is a flowchart of the first embodiment of the method of the present invention. Figure 2 This is a schematic diagram of steps S110 to S130 of the first embodiment of the method of the present invention. Figure 3 This is a schematic diagram of step S140 of the first embodiment of the method of the present invention. Figure 4 This is a schematic diagram of steps S150 and S160 of the first embodiment of the method of the present invention. The present invention provides a method for manufacturing an elastically fatigued horn diaphragm, comprising the following steps:

[0061] Step S110, as follows Figure 1 and Figure 2 As shown, a slit 12 is formed between two trumpet vibrator forming blocks 11 of a substrate 10. The length of the slit 12 is greater than or equal to the width of the trumpet vibrator forming blocks 11. Specifically, multiple yarns (not shown) are woven into the substrate 10, including multiple warp yarns and multiple weft yarns. The substrate 10 is moved below a cutting device 20, which cuts the warp yarns extending through the trumpet vibrator forming blocks 11 between them to form the slit 12. In other words, the slit 12 can break the warp yarns extending through the trumpet vibrator forming blocks 11. Preferably, the yarns are bamboo fiber, cotton fiber, silk fiber, hemp fiber, wool fiber, polyester fiber, acrylic fiber, polyvinyl naphthenic fiber, rayon fiber, rubber fiber, nylon fiber, elastic fiber, acetate fiber, or combinations thereof.

[0062] Step S120, as follows Figure 1 and Figure 2As shown, the substrate 10 is immersed in a resin solution 31. Specifically, the resin solution 31 is contained in a resin tank 30, and the substrate 10 is placed into the resin tank 30 so that it is immersed in the resin solution 31, allowing the yarns to absorb and adhere to the resin. The resin contains solids such as alcohol and water, and its content accounts for more than 50% of the liquid resin. Preferably, the resin composition is selected from one or a combination of phenolic resin, epoxy resin, polyester resin, rubber, and silicone, or other resin materials with similar properties.

[0063] Step S130, as follows Figure 1 and Figure 2 As shown, the substrate 10 is dried. More specifically, the substrate 10 is moved between an upper baking plate 41 and a lower baking plate 42 of a drying apparatus 40, and the substrate 10 is dried by a drying temperature of the upper baking plate 41 and the lower baking plate 42, so that the moisture and volatile substances in the resin on the substrate 10 are removed, thereby drying the substrate 10. At the same time, the resin penetrates into the substrate 10 and adheres to the yarns to form a resin solid layer (not shown). The resin solid layer covers the surface of the yarns, thereby giving the substrate 10 appropriate hardness, elasticity and toughness.

[0064] Step S140, as follows Figure 1 and Figure 3 As shown, multiple pulling devices 50 press against the periphery of the horn diaphragm forming block 11, and these pulling devices 50 pull the horn diaphragm forming block 11 outward in different directions, causing the horn diaphragm forming block 11 to lose its elasticity. In the first embodiment, the pulling devices 50 are multiple corner posts 51 to 54, which press against multiple corners 111 to 114 of the horn diaphragm forming block 11; and the corner posts 51 and 53 pull outward in opposite directions the diagonally opposite corners 111 and 113 of the horn diaphragm forming block 11, and the corner posts 52 and 54 pull outward in opposite directions the diagonally opposite corners 112 and 114 of the horn diaphragm forming block 11. In other words, the equilateral pillars 51-54 apply four opposing forces along the two diagonals L1 and L2 to pull the trumpet diaphragm forming block 11 outwards, and each yarn is pulled by all four forces. The closer the yarn is to the corners 111-114, the stronger the pull from two of the forces from the equilateral pillars 51-54, and the weaker the pull from the other two forces. Overall, the four forces from the equilateral pillars 51-54 pulling the trumpet diaphragm forming block 11 are evenly distributed outwards along the two diagonals L1 and L2, so the pulling force on each yarn is the same, making the overall elastic fatigue of the trumpet diaphragm forming block 11 quite uniform.

[0065] Step S150, as follows Figure 1 andFigure 4 As shown, a horn diaphragm 100 is formed by heating and pressurizing the horn diaphragm forming block 11. More specifically, the substrate 10 is moved between an upper mold 611 and a lower mold 612 of a molding die 61 of a thermoforming apparatus 60. When the upper mold 611 and the lower mold 612 are closed and pressure is applied to the horn diaphragm forming block 11, a heating device (not shown) of the thermoforming apparatus 60 is energized to raise the temperature of the upper mold 611 and the lower mold 612 to 190°C to 270°C, thereby softening the resin on the substrate 10. The resin melts from a solid state to a flowable liquid state, filling the gaps and connecting to form a resin solid layer, which covers the outer surface of the yarns, thereby forming the horn diaphragm 100 by heating and pressurizing the horn diaphragm forming block 11.

[0066] Step S160, as follows Figure 1 and Figure 4 As shown, the horn diaphragm 100 is separated from the substrate 10. Specifically, the substrate 10 is moved between an upper cutter 71 and a lower cutter 72 of a cutting device 70, and the upper cutter 71 and the lower cutter 72 cut the horn diaphragm 100 from the substrate 10, thereby separating the horn diaphragm 100 from the substrate 10.

[0067] Therefore, the method of the present invention first loosens the yarn of the trumpet vibrator forming block 11 by means of the pulling device 50, so that the trumpet vibrator forming block 11 loses its elasticity, and then heats and presses the elastically fatigued trumpet vibrator forming block 11 to form the trumpet vibrator 100. Therefore, all the yarns of the trumpet vibrator forming block 11 are subjected to equal wrinkling force, so that the wrinkling force of the trumpet vibrator forming block 11 is relatively uniform, and the resulting trumpet vibrator 100 will not deform.

[0068] Furthermore, the method of the present invention forms slits 12 between the trumpet vibrator forming blocks 11, which can break the warp yarns extending through the trumpet vibrator forming blocks 11. Therefore, during the continuous heating and pressing of the trumpet vibrator forming blocks 11 to form multiple trumpet vibrators 100, the wrinkling force of the previous trumpet vibrator forming block 11 is limited between the previous trumpet vibrator forming block 11 and the slit 12, and will not pull the yarn between the next trumpet vibrator forming block 11 and the slit 12. Therefore, the position of the trumpet vibrator forming blocks 11 can remain unchanged, and the spacing distance can also remain unchanged, without any deviation problem, thus reducing the amount of waste generated.

[0069] Furthermore, the method of the present invention forms slits 12 between the horn diaphragm forming blocks 11, which can break the warp yarns extending through the horn diaphragm forming blocks 11. Therefore, when the next horn diaphragm forming block 11 is heated and pressurized to form the next horn diaphragm 100, the yarn between the next horn diaphragm 100 and the slit 12 is pulled backward by the wrinkling force, but it will not pull the yarn between the previous horn diaphragm 100 and the slit 12. Thus, the yarn between the horn diaphragms 100 will not be torn, and the substrate 10 will not be torn.

[0070] Figure 5 This is a schematic diagram of step S140 of the second embodiment of the method of the present invention. Figure 5 As shown, the difference between the second embodiment and the first embodiment is that the pulling device 50 consists of multiple side posts 55-58, which respectively press down on multiple sides 115-118 of the trumpet vibrator forming block 11; and the side posts 55 and 57 pull the opposite sides 115 and 117 of the trumpet vibrator forming block 11 outward in opposite directions, and the side posts 56 and 58 pull the opposite sides 116 and 118 of the trumpet vibrator forming block 11 outward in opposite directions. In other words, the side posts 55-58 apply four opposite forces along the two center lines L3 and L4 to pull the trumpet vibrator forming block 11 outward, and each yarn can be pulled by four forces. The yarns closer to the sides 115-118 are pulled more strongly by one of the forces of the equilateral pillars 55-58, and pulled less by the other three forces of the equilateral pillars 55-58. Overall, the four forces pulling the trumpet diaphragm forming block 11 by the equilateral pillars 55-58 are evenly diffused outward along the two center lines L3 and L4, so the pulling force on each yarn is the same, making the overall elastic fatigue of the trumpet diaphragm forming block 11 quite uniform.

[0071] Figure 6 This is a schematic diagram of step S140 of the third embodiment of the method of the present invention. Figure 6As shown, the difference between the third embodiment and the first embodiment is that the pulling device 50 includes multiple corner posts 51-54 and multiple side posts 55-58. The corner posts 51-54 respectively press down on multiple corners 111-114 of the horn diaphragm forming block 11, and the side posts 55-58 respectively press down on multiple sides 115-118 of the horn diaphragm forming block 11; and the corner posts 51 and 53 pull outwards in opposite directions the diagonally opposite sides of the horn diaphragm forming block 11. The corners 111 and 113, and the two opposite corners 112 and 114 of the horn diaphragm forming block 11 pulled outward in opposite directions by the equilateral pillars 52 and 54, while the equilateral pillars 55 and 57 pull outward in opposite directions by the opposite sides 115 and 117 of the horn diaphragm forming block 11, and the equilateral pillars 56 and 58 pull outward in opposite directions by the opposite sides 116 and 118 of the horn diaphragm forming block 11. In other words, the third embodiment possesses all the technical features of the first and second embodiments. Therefore, the equilateral pillars 51-54 apply four opposing forces along the two diagonals L1 and L2 to pull the trumpet vibrator forming block 11 outward, while the equilateral pillars 55-58 apply four opposing forces along the two centerlines L3 and L4 to pull the trumpet vibrator forming block 11 outward. Each yarn is pulled by eight forces. Because each yarn is pulled by eight forces, the overall elastic fatigue of the trumpet vibrator forming block 11 is most uniform.

[0072] Figure 7 This is a flowchart of the fourth embodiment of the method of the present invention. Figure 8 This is a schematic diagram of steps S210 to S230 of the fourth embodiment of the method of the present invention. Figure 7 and Figure 8 As shown, the fourth embodiment differs from the first, second, and third embodiments in that: in step S210, the substrate 10 is immersed in the resin solution 31; in step S220, a slit 12 is formed between the two horn vibrator forming blocks 11 of the substrate 10, the length of the slit 12 being greater than or equal to the width of the horn vibrator forming blocks 11. Apart from this, step S230 of the fourth embodiment is exactly the same as step S130 of the first, second, and third embodiments; step S240 of the fourth embodiment is exactly the same as step S140 of the first, second, and third embodiments; step S250 of the fourth embodiment is exactly the same as step S150 of the first, second, and third embodiments; and step S260 of the fourth embodiment is exactly the same as step S160 of the first, second, and third embodiments.

Figure 10 This is a schematic diagram of steps S310 to S330 of the fifth embodiment of the method of the present invention. Figure 9 and Figure 10 As shown, the fifth embodiment differs from the first, second, and third embodiments in the following ways: in step S310, the substrate 10 is immersed in the resin solution 31; in step S320, the substrate 10 is dried; in step S330, a slit 12 is formed between the two horn vibrator forming blocks 11 of the substrate 10, the length of the slit 12 being greater than or equal to the width of the horn vibrator forming blocks 11. Apart from this, step S340 of the fifth embodiment is exactly the same as step S140 of the first, second, and third embodiments; step S350 of the fifth embodiment is exactly the same as step S150 of the first, second, and third embodiments; and step S360 of the fifth embodiment is exactly the same as step S160 of the first, second, and third embodiments.
