Abstract
A loudspeaker unit includes: a housing (100), a magnetic assembly (300) disposed in the housing (100), a diaphragm (220) disposed on the housing (100), a first voice coil (210a) connected to the diaphragm (220), and the magnetic assembly (300) is connected to the housing (100) by an elastic element (400). The magnetic assembly (300) vibrates along with the elastic element (300) with respect to the housing (100) when the elastic element (400) vibrates.
