The present disclosure mainly relates to a loudspeaker and an electronic device. The loudspeaker includes a basket and a coil. The coil includes an annular body and a lead wire connected with the annular body. The annular body is located on an inner side of the basket. The lead wire moves along with the annular body relative to the basket after an excitation signal is input into the loudspeaker. An avoidance groove is disposed on the basket. An orthographic projection of the lead wire along a vibration direction of the loudspeaker at least partially falls within the avoidance groove. The avoidance groove can increase the distance between the lead wire of the coil and the basket to a certain extent, so as to reduce the risk of collision between the lead wire and the basket when the lead wire moves along with the annular body of the coil relative to the basket, especially when the loudspeaker operates at a small amplitude, and reduce the travel of the lead wire after colliding with the basket, especially when the loudspeaker operates at a large amplitude, thereby improving the reliability of the loudspeaker.
