Abstract: This application relates to a loudspeaker and an electronic device. In one example, the loudspeaker includes a cone frame, a first sounding unit, a second sounding unit, and an elastic suspension. The first sounding unit includes a magnetic circuit structure mounted on the cone frame, an annular vibrating diaphragm, and a voice coil connected to the annular vibrating diaphragm. The second sounding unit is arranged coaxially with the first sounding unit, where the second sounding unit is mounted in the middle of a side that is of the magnetic circuit structure and that faces the annular vibrating diaphragm. The elastic suspension is configured to elastically support the voice coil and the annular vibrating diaphragm on the cone frame.
