Title: VIBRATING ACOUSTIC DEVICE
Abstract:
The invention relates to the technical field of electrical acoustic products, and specifically, to a vibrating acoustic device comprising a housing, and a vibration system and a magnetic system accommodated in the housing. One side surface of the housing is provided with a sound hole. The vibration system comprises a diaphragm, a voice coil, and a voice coil frame connecting the diaphragm and the voice coil. The voice coil is flat in structure, and is located on a plane perpendicular to a plane where the diaphragm is located. The magnetic system comprises a magnet located on a plane parallel to the plane where the voice coil is located. The vibrating acoustic device also comprises a mass piece and an elastic support piece. The elastic support piece is configured to suspend the mass piece and the magnet in the housing, and has a ring-shaped structure. The mass piece and the magnet are located at an inner side of the elastic support piece. Two opposite sides of the elastic support piece are fixedly connected to the magnet, and other two opposite sides of the elastic support piece are fixed to the housing.
