Abstract
Disclosed is a speaker having a suspension. The suspension includes a vibrating arm having at least a pair of layer structures and an insulating layer sandwiched between the two layer structures. Each layer structure has a foil signal transmission layer, a hardness reinforcement layer and a glue layer for connecting the foil signal transmission layer with the hardness reinforcement layer and a conductive portion for electrically connecting the foil signal transmission layers of each of layer structures. The suspension of the disclosure can prevent the signal layer from being broken. The suspension disclosed has at least two layer structures, which makes the signal transmitted in each layer structures at the same time, even if one of the layer structures is broken, the rest of the layer structures can still be working.
