Description

TECHNICAL FIELD

[0001] The present invention relates to a manufacturing method of a vibrating plate, and more particularly to a manufacturing method of a vibrating plate for positioning a horn. BACKGROUND

[0002] Generally, a horn includes a bass unit, a medium unit, and a treble unit, which are responsible for different frequencies. Most of the horns work on the same principle. For example, in a typical moving coil horn, when an electric current flows through the wire to the voice coil, an electromagnetic field is generated. Since the electromagnetic field is perpendicular to the magnetic field of the permanent magnet on the horn, the moving coil is forced to move in the gap. The mechanical force generated by this movement causes the paper disc attached to the voice coil to vibrate vertically up and down, thereby causing the air to vibrate, emitting audio to the human ear, achieving the purpose of sound restoration for listening, realizing the conversion of electric energy to sound energy.

[0003] However, the damper (also known as a spring wave) in the horn is connected to the voice coil, and the main function of the damper is to suspend the voice coil and the drum paper. The structure of the damper is mostly composed of multiple concentric circles with a wavy cross-section. The damper can support the voice coil and the drum paper, so the quality of the damper directly affects the amplitude of the drum paper and the sound quality of the horn.

[0004] In addition, the current damper includes a damper body, a paper ring, and multiple wires. The paper ring is arranged on the outer periphery of the damper body and is fixedly combined with the damper body through the wires. One end of the wire is connected to the voice coil, and the other end is connected to the input terminal. The traditional molded damper mainly uses cotton cloth as the basic material. The cotton cloth is immersed in liquid synthetic resin, and the fibers of the cotton cloth absorb the synthetic resin. After drying and hardening, the cotton cloth that has absorbed the synthetic resin is further subjected to multiple molding die feeding, warming, pressurizing, and cutting to form a wire damper with a ring-shaped wave on the surface.

[0005] However, during the feeding process of the traditional damper, the paper ring on the cotton cloth is offset and misaligned due to human or mechanical equipment during the initial arrangement of the paper ring and the cotton cloth. Subsequently, during the warming and pressurizing process of the manufacturing mold, the paper ring is also affected and misaligned, thereby reducing the pass rate of the production products.

[0006] Furthermore, if a defective damper is used, the wires of the damper cannot be stably connected to the voice coil and the input terminal, thereby affecting the output of the horn sound quality. In addition, there is a possibility that the damper will deform, loosen, or break after a long period of vibration due to the misalignment of the paper ring.

[0007] Therefore, the present inventor believes that the feeding equipment still needs to be further improved after observing the above-mentioned deficiencies, and thus the present invention is produced. SUMMARY

[0008] The main object of the present application is to provide a manufacturing method for positioning a loudspeaker diaphragm, which is used to position a paper ring and a cotton cloth in a production line of a loudspeaker diaphragm, to further convert the operation mode into an automatic processing mode, to more accurately position, to smoothly set the paper ring on the cotton cloth, and to improve the yield of products, thereby improving the poor yield of manual processing, reducing the process cost, and achieving the effects of reducing manpower, saving manufacturing time, and improving productivity.

[0009] To achieve the above object, the present application provides a manufacturing method for positioning a loudspeaker diaphragm, which comprises: a placement step of sequentially placing a paper ring and a cotton cloth on a bearing surface of a first mold; a positioning step of moving a second mold relative to the first mold in a direction close to the first mold, so that an adsorption surface of the second mold corresponds to the bearing surface, and at least one protrusion of the second mold contacts at least one positioning component of the first mold; an adsorption step of providing a plurality of adsorption holes of the second mold corresponding to the paper ring and the cotton cloth, the plurality of adsorption holes providing suction, and the plurality of adsorption holes adsorbing the paper ring and the cotton cloth; a feeding step of moving the second mold relative to a first forming mold in a direction away from the first forming mold after the second mold adsorbs the paper ring and the cotton cloth, so that the second mold moves the paper ring and the cotton cloth to a compression surface of the first forming mold; and a homing step of moving the second mold relative to the first forming mold in a direction away from the first forming mold after the second mold places the paper ring and the cotton cloth.

[0010] Preferably, in the placement step, a first paper ring positioning step of placing the paper ring on a paper ring placement groove of the bearing surface is included, and a width of the paper ring placement groove is greater than or equal to a thickness of the paper ring.

[0011] Preferably, in the positioning step, a positioning groove is recessed at a contact end of the protrusion and the positioning component, and a profile shape of the positioning groove matches a profile shape of the top end of the protrusion.

[0012] Preferably, in the placement step, the cotton cloth is placed on a top side of the paper ring, and the positioning component penetrates the cotton cloth.

[0013] Preferably, in the adsorption step, the plurality of adsorption holes of the adsorption surface of the second mold adsorb the paper ring and the cotton cloth, and the paper ring and the cotton cloth are positioned on the adsorption surface of the second mold when the plurality of adsorption holes are in operation.

[0014] Preferably, in the feeding step, a second paper ring positioning step of placing the paper ring on a compression paper ring placement groove of the compression surface of the first forming mold is included when the second mold moves the paper ring and the cotton cloth to the first forming mold.

[0015] Preferably, after the homing step, a molding step is included, in which a second molding die is displaced relative to the first molding die in a direction toward the first molding die, a molding surface of the second molding die facing the compression surface, the compression surface and the molding surface molding the paper ring and the cotton cloth into a diaphragm.

[0017] Preferably, the compression surface of the first molding die is concave with a compression wave portion, and the molding surface of the second molding die is concave with a molding wave portion.

[0077] Therefore, the present application has the following implementation effects and technical effects.

[0078] Firstly, the material arranging step S01 is used to arrange the paper ring 10 and the cotton cloth 20 on the bearing surface 31 of the first mold 30 in sequence. The paper ring 10 is arranged in the paper ring arranging groove 311 of the bearing surface 31. The width of the paper ring arranging groove 311 is greater than or equal to the thickness of the paper ring 10. Therefore, the positions of the paper ring 10 and the cotton cloth 20 can be accurately positioned before the manufacturing starts.

[0079] Secondly, the second mold 40 is displaced relative to the first mold 30 in a direction towards the first mold 30, and the protrusion 42 of the second mold 40 touches the positioning assembly 32 of the first mold 30, the touch end of the protrusion 42 is recessed with the positioning groove 321, so that the relative operating position of the second mold 40 and the first mold 30 can be positioned before the paper ring 10 and the cotton cloth 20 are adsorbed, and the adsorption positions of the plurality of suction holes 43, the paper ring 10 and the cotton cloth 20 are positioned at the same time.

[0080] Thirdly, the second mold 40 adsorbs the paper ring 10 and the cotton cloth 20, and the second mold 40 sends the paper ring 10 and the cotton cloth 20 to the first forming mold 50, the paper ring 10 is placed to the pressing paper ring placing groove 511 of the pressing surface 51 of the first forming mold 50, so that the position of the paper ring 10 and the cotton cloth 20 can be accurately positioned again, the paper ring 10 is stably arranged on the cotton cloth 20, and the qualified rate of products can be improved, so that the problem of poor qualified rate of artificial processing is improved, and the process cost is reduced.
