Abstract: A receiver is provided in the present invention. The receiver includes: a housing having a hollow inner cavity; a diaphragm mechanism disposed in the hollow inner cavity, partitioning the hollow inner cavity into a first cavity and a second cavity, and including a vibration plate; and an electromagnetic driving mechanism disposed in the hollow inner cavity and including a coil assembly and at least one magnetic field generation member. Each magnetic field generation member is disposed in the first cavity or the second cavity, and the magnetic field generation member is close to a free end of the vibration plate. The coil assembly is disposed in the second cavity and includes a coil and a magnetic core. The coil and the vibration plate are placed in the same direction. The magnetic core is inserted in a hollow inner hole of the coil.

Abstract: A receiver is provided in the present invention. The receiver includes: a housing having a hollow inner cavity; a diaphragm mechanism disposed in the hollow inner cavity and configured for partitioning the hollow inner cavity into a first cavity and a second cavity, the diaphragm mechanism including a vibration plate, a fixed end of the vibration plate being fixed to an inner wall of the housing, and a free end of the vibration plate being suspended in the hollow inner cavity; an electromagnetic driving mechanism disposed in the hollow inner cavity and including at least one coil assembly and at least one magnetic field assembly, each magnetic field assembly being disposed in the first cavity or the second cavity and being close to the free end of the vibration plate, and each coil assembly being disposed in the first cavity or the second cavity and being close to the fixed end of the vibration plate.
