The invention provides a voice coil and an electrodynamic speaker. The electrodynamic speaker uses the tabulate voice coil in scroll direction vertical to the vibrating direction of a speaker vibration plate and is long and thin with short diameter being smaller than the long diameter. The electrodynamic speaker has superior voice reproduction capacity and is suitable for being mounted on equipment such as a display. The voice coil is formed by bonding end surfaces of the first and second coils as the tabulate hollow coils by way of making the first coil and second coils consistent with respective scrolls and connecting the bonded first and second coils in series or in parallel by way of flowing voice signal current in a same direction. The hollow coil is formed by winding the flat wire in multiple layers in a non-staggered manner relative to the scrolls and comprises a reinforcing board which is accommodated in an internal peripheral space regulated by an internal peripheral end part formed by bonding the first and second coils. The internal peripheral end part is matched with the external peripheral end part.
