The present invention provides a speaker including: a frame, a vibration system and a magnetic circuit system. The vibration system includes a vibration diaphragm and a voice coil. The magnetic circuit system includes a magnetic part, and the voice coil is arranged around the magnetic part. The vibration system further includes an elastic plate with two branch elastic plates. The branch elastic plate includes a connection part, an extension part, an elastic arm and a fixed part. The surfaces of the connection part and the extension part facing the connection surface are recessed together to form a welding slot, and the lead wire is accommodated in the welding slot. The speaker provided by the present invention can not only effectively prevent the voice coil from swaying, but also reduce the number of parts to simplify the product structure.
