Abstract: This application relate to the field of electronic device technologies, and in particular, to a loudspeaker and an electronic device. Embodiments of this application are provided to resolve a technical problem of insufficient sensitivity of a loudspeaker caused by a small electromagnetic driving force that drives a voice coil to vibrate. According to a loudspeaker and an electronic device in embodiments of this application, a yoke includes a bottom part and a sleeve located on the side of the bottom part. An annular magnet is sleeved on the outer side of the sleeve. A voice coil is sleeved on the sleeve and located between the magnet and the sleeve. A damper is located in a region enclosed by the sleeve. An outer edge of the damper is connected to the voice coil, and a middle part of the damper is connected to the yoke.
