Horn vibrating piece with twist structure

This creation is related to a wire horn vibrating piece, and in particular to a horn vibrating piece having a twisted structure.

Press, the general speaker includes the woofer, the midrange unit, and the tweeter. These three units are responsible for different frequencies. Most speakers work on the same principle. Like a typical moving coil horn, an electromagnetic field is generated when current flows through the wire to the voice coil. Since this electromagnetic field is at right angles to the magnetic field of the permanent magnet on the horn, this forces the movable coil to be subjected to motion within the gap. The mechanical force generated by this movement causes the paper tray attached to the voice coil to vibrate vertically, up and down, thereby vibrating the air, transmitting audio to the human ear, achieving the purpose of sound restoration for listening, and realizing electrical energy to sound energy. Conversion.

However, since the damper (also known as the elastic wave) in the horn is connected to the voice coil, and the main function of the vibrating piece is used to hang the voice coil and the drum paper, the structure is mostly a plurality of concentric circles and the cross section is The wavy shape can support the voice coil and the drum paper by the vibrating piece. Therefore, the vibrating piece can directly affect the amplitude of the drum paper and affect the sound quality of the horn.

In addition, the current wire vibrating piece comprises a body and a plurality of wires, and is fixedly coupled to the body through at least one wire, and one end of the wire is connected to the voice coil, and the other end is connected to the input terminal. The conventionally used shaped wire vibrating piece mainly uses cotton cloth as a basic material, and the cotton cloth is dipped in a liquid synthetic resin, so that the fiber of the cotton cloth absorbs the synthetic resin, and the cotton cloth absorbing the synthetic resin is dried and hardened, and further passes through the manufacturing mold. The wire vibrating piece having the annular corrugation on the surface is formed by heating, pressurizing, and cutting. Due to the conventional method of forming the wire vibrating piece, when the mold is heated and pressurized by the elastic wave, the wire is also misaligned when the mold is heated and pressurized, thereby improving the defective rate of the production product; When the wire is initially placed, the wire is offset and misaligned on the body due to factors such as human or mechanical equipment, thereby improving the defect rate of the production product.

Furthermore, if a defective product is used, the wire of the wire vibrating piece cannot be stably connected to the voice coil and the input terminal, thereby affecting the output of the speaker sound quality. In addition, the wire is more likely to be displaced due to the problem of misalignment after a long period of vibration of the vibrating piece. The condition of loose or broken deformation.
