Ultrafine Magnetic Copper Wire For Voice Coils Windings Enamel Insulated

Typically, the diameter of the varnished copper wire used to make the voice coil varies depending on the desired electrical properties. The electrical characteristics of the voice coil affect the speaker's sensitivity, power handling capabilities, and frequency response. In order to select the appropriate wire size, you may need to do some design and testing work to ensure that the final voice coil meets the required specifications and performance.

Typically, the diameter of the varnished copper wire used for the voice coil will be between 0.1 mm and 1 mm. Different speaker designs and specifications may require different diameter wires. For more precise advice, you may want to consult a professional sound engineer or speaker manufacturer.
