Products Description
Simply put, it means that the coil is energized to generate a magnetic field, which works together with the magnetic circuit magnetic field to generate a downward or upward force, driving the paper bowl to move, and the paper bowl pushes the air to make a sound.
●CCAW (Copper Clad Aluminum Wire) is lighter than copper wire, has higher conductivity and tensile strength than aluminum wire. Its impedance at high frequencies is similar to that of copper wire. Speakers made with CCAW have good transient characteristics and high sensitivity, making it a commonly used material in high sensitivity speakers.
● Flat wire
The magnetic field utilization rate is higher than that of circular wires (78%~91% for circular wires and 96% for flat wires), characterized by high energy conversion efficiency, suitable for producing high-power speakers, and flat aluminum wires are more commonly used for professional speakers (high-power, high sensitivity)
●Circular self-adhesive enameled wire is a commonly used voice coil wire. In the voice coil, in order to increase the withstand current and power, the wire diameter needs to be increased. As the wire diameter increases, the required magnetic gap becomes larger. As the magnetic gap increases, the power efficiency decreases. Therefore, the middle value can only be selected based on the characteristics of the speaker. The voice coil usually needs to be wound in two layers, and it is difficult to set up single layer lead wires. The coil is wound on a rigid material skeleton, and high-power speakers use aluminum sheets as the skeleton material.
The utilization rate of flat wire magnetic field is higher than that of circular wire (the utilization rate of circular wire magnetic field is 78%~91%, and flat wire is 96%), characterized by high energy conversion efficiency, suitable for producing high-power speakers. Flat aluminum wire is more commonly used for professional speakers (high-power, sensitivity).
Circular wire has hot air wire and alcohol wire, which are commonly used wires for horn voice coils, and various processes are already relatively mature. At present, single axis and six axis winding machines are commonly used models, but for flat wire, six axis winding machines cannot winding, and ordinary single axis winding machines cannot winding flat wire. During the winding process of flat wire, the wire cannot be flipped and must always maintain a relative direction, which puts higher requirements on the wiring arrangement.
Traditional single axis winding machines only need to adjust the tension of the tensioner and the position of the winding when winding circular wire, and the rotation of the circular wire along the center will not affect the winding effect. In addition to tension and winding position, the flat wire winding machine also needs to maintain the direction of the flat wire unchanged, which is relatively more difficult.
