BASV99.8 voice coil is light in weight and good in rigidity: the electromagnetic force generated by the BASV99.8 voice coil when the speaker sounds drives the BASV99.8 voice coil and the cone to vibrate together. The lighter the skeleton of the BASV99.8 voice coil, the total weight of the vibration system The lighter the speaker, the more efficient the speaker and the more audible the sound. The light weight can effectively improve the efficiency and sound quality of your speaker. The speaker is based on the BASV99.8 voice coil skeleton to push the diaphragm (sound basin) and vibrate, so the BASV99.8 voice coil skeleton is required to be rigid enough. To ensure that your speakers still emit Hi-Fi beeps under high power and large kinetic energy range.
The inner surface is smooth and smooth: the magnetic gap of the speaker is small, and the BASV99.8 voice coil is placed in it. The small deformation or burr of the BASV99.8 voice coil bobbin will touch the magnetic circuit components and produce abnormal sound. The aluminum BASV99.8 voice coil skeleton is cut very fine, smooth and burr-free, making the sound quality of your speakers absolutely pure.
The surface is smooth and smooth: the smoothness and flatness of the surface is an important indicator for evaluating the quality of the soundtrack of BASV99.8.
For non-conductors, no internal magnetic field turbulence is generated: the metal BASV99.8 voice coil bobbin generates turbulence, which consumes part of the energy, which reduces the efficiency of the speaker and affects the magnetic field in the magnetic gap. The effective frequency range of the speaker becomes smaller, and asbestos is not a conductor, which prevents the adverse effects of turbulence.
Generally, the enameled wire used in the BASV99.8 voice coil is a self-melting enameled wire, and the self-melting enameled wire is a double-layer paint film, which is made of polyurethane or polyester or other kinds of insulating paint film, and is covered with a thermoplastic or thermosetting resin. Bake on the surface of the conductor. A variety of different insulating paint films and melted paint films are combined with each other to form different types of self-melting enameled wires.
The conductor part generally has oxygen-free copper, copper-clad aluminum, and pure aluminum:
1. The solderability and corrosion resistance of the copper wire conductor are better.
2. The conductor of the copper clad aluminum wire is a composite material mainly composed of aluminum and coated with copper, and has the lightness of aluminum and the direct solderability and corrosion resistance of copper.
3. The weight of the pure aluminum wire conductor is only about 30% of the copper wire, which effectively reduces the weight of the coil. The conductivity is more than 61% of copper, and under the same conductor resistance, its weight is about half of that of copper. Therefore, the working efficiency of the speaker can be improved, and the high frequency can also be expanded.
