Abstract: A voice coil and a miniature loudspeaker provided with the voice coil, which relate to the technical field of electro-acoustic products. The voice coil is formed by winding a wire. The number of wound layers of the wire is an even number. There is a height difference between a starting outgoing line position of the wire located at the innermost layer and a tail outgoing line position of the wire located at the outermost layer; and the height difference is less than 1.5 times the diameter of the wire. The voice coil and the miniature loudspeaker provided with the voice coil of the present invention solve the technical problem in the prior art that a voice coil breaks easily when working under large displacement. A voice coil lead of the voice coil and the miniature loudspeaker provided with the voice coil of the present invention is not easily broken and highly reliable, has a long service life, and can be suitable for a developmental tendency of miniature loudspeaker products.
