Abstract: A ribbon speaker includes a housing, first and second magnet assemblies, a ribbon diaphragm, a coil, and a flexible substrate. The first and second magnet assemblies is arranged in the housing. The same poles of the first magnet assembly and the second magnet assembly are arranged opposite to each other. The diaphragm is positioned between these magnet assemblies. The coil, placed on this diaphragm, includes two first connection portions. The flexible substrate includes a body, two connection portions, and two soldering portions. The body's first part is inside the housing, while the second part arranged outside. The second connections on the body's first part electrically connected to the coil's first connections. The externally positioned soldering portions facilitate easier assembly, significantly reducing soldering complexity. The soldering portions are respectively and electrically connected to the second connection portions.
