Description

Manufacturing method for positioning horn diaphragm

The present invention relates to a manufacturing method of a vibrating plate, in particular to a manufacturing method for positioning a horn vibrating plate.

Press, a general speaker includes a woofer, a midrange unit, and a tweeter, and these three units are responsible for different frequencies. Most horns work on the same principle. As in a typical moving coil speaker, when current flows through the wire to the voice coil, an electromagnetic field is generated. Since this electromagnetic field is oriented at right angles to the magnetic field of the permanent magnet on the horn, this forces the moving coil to move within the gap. The mechanical force generated by this movement causes the paper plate attached to the voice coil to vibrate vertically and up and down, so that the air vibrates, and the audio is transmitted to the human ear, achieving the purpose of restoring the sound for people to listen to, and realizing the transformation from electric energy to sound energy. transform.

However, since the vibrating plate (Damper, also known as elastic wave) in the speaker will be connected with the voice coil, and the main function of the vibrating plate is to suspend the voice coil and the drum paper, its structure is mostly concentric circles with a cross-section It is wavy, and the vibrating plate can support the voice coil and the drum paper, so the quality of the vibrating plate can directly affect the amplitude of the drum paper, and affect the sound quality of the speaker.

In addition, the current vibrating piece includes a spring wave body, a paper ring and a plurality of wires. The paper ring is arranged on the outer periphery of the spring wave body, and is fixedly combined with the spring wave body through the wire, and one end of the wire is connected to the voice coil. Connect the other end to the input terminal. Traditionally used forming vibrators are mainly based on cotton cloth, which is dipped in liquid synthetic resin to absorb synthetic resin in the fibers of the cotton cloth. After drying and hardening, the cotton cloth that absorbs synthetic resin is further fed through multiple forming molds. , heating, pressurizing and cutting to form a wire vibrating piece with ring-shaped corrugations on the surface.

However, due to the traditional vibrating plate feeding process, when the paper ring and cotton cloth are initially arranged by human or mechanical equipment, the paper ring is shifted and misplaced on the cotton cloth, and when the mold is heated and pressurized, the paper ring will lose its position. The ring will also be affected and misplaced, which will increase the defect rate of the produced products.

Furthermore, if a defective vibrating piece is used, the wires of the vibrating piece cannot be connected firmly In the voice coil and input terminal, thus affecting the output of the sound quality of the speaker. In addition, it is more likely that due to the dislocation of the paper ring, the vibrating piece will be deformed, loosened or broken after a long period of vibration.

Therefore, after observing the above-mentioned deficiency, the inventor of the present case thinks that there is still a need for further improvement of the feeding equipment, and thus the present invention is produced.

The main purpose of the present invention is to provide a manufacturing method for positioning the speaker vibrating piece, which is used to position the paper ring and cotton cloth when swinging and feeding materials, so as to be used in the production line of the horn vibrating piece, and further converted into an automatic processing method. The operation mode can more accurately align and set the paper ring on the cotton cloth smoothly, and can improve the yield rate of the product, thereby improving the problem of poor yield rate caused by manual processing, and reducing the cost of the process, so as to reduce manpower and save The effect of increasing production capacity by manufacturing man-hours.

Thus, the present invention has the following implementation effects and technical effects:

First, the present invention places the paper ring 10 and the cotton cloth 20 on the bearing surface 31 of the first mold 30 in sequence through the placing step S01, and the paper ring 10 is correspondingly placed on the bearing surface. The paper ring placement groove 311 on the surface 31, the width of the paper ring placement groove 311 is greater than or equal to the thickness of the paper ring 10, so that the position of the paper ring 10 and the cotton cloth 20 can be accurately positioned before the manufacturing begins .

Second, through the positioning step S02 of the present invention, the adsorption surface 41 of the second mold 40 corresponds to the carrying surface 31, and the second mold 40 is relatively close to the first mold 30 relative to the first mold 30. The mold 30 is displaced, and the protrusion 42 of the second mold 40 touches the positioning element 32 of the first mold 30, and the positioning groove is recessed at the contact end of the positioning element 32 and the protrusion 42 321, so that the relative operating positions 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 suction holes 43, the paper ring 10 and the cotton cloth 20 can be positioned at the same time Adsorption position.

Third, through the feeding step S04 of the present invention, the second mold 40 absorbs 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 and the cotton cloth 20 are placed on the pressing surface 51 of the first forming mold 50, 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 correspondingly placed in the pressing paper ring placement groove 511 of the pressing surface 51, so that the positions of the paper ring 10 and the cotton cloth 20 can be accurately positioned again, and the The paper ring 10 is arranged on the cotton cloth 20, and can improve the yield rate of the product, thereby improving the problem of poor yield rate caused by manual processing, and reducing the manufacturing process cost.

To sum up, the present invention has excellent progressive practicability among similar products. At the same time, the technical data about this type of structure has been searched at home and abroad, and no similar structure has been found in the literature. Therefore, The present invention already meets the requirements of an invention patent, and an application is filed according to the law.

However, what is described above is only a preferred embodiment of the present invention, so all equivalent structural changes made by applying the description of the present invention and the scope of the patent application should be included in the patent scope of the present invention.
