A vibration exciter having an elastic support, comprising a cavity cover (1) and a vibration base (5). One side of the cavity cover (1) is provided with a PCB assembly plate (8), and a PCB is provided in the PCB assembly plate (8). An excitation signal is input into a voice coil (7) provided on the periphery of a main and auxiliary magnet (6) by means of the PCB, so that the vibration base (5) provided on the periphery of the voice coil (7) is driven, and the vibration base (5) is connected to a supporting plate (4) so that vibration is delivered to the supporting plate (4) and then is delivered to the elastic support (3) by means of the supporting plate (4), the cavity cover (1) is driven to vibrate, and a screen connected to the bottom of the cavity cover (1) is driven to vibrate. Such a structure effectively reduces a resonant frequency of the exciter, and improves the amplitude of the exciter; moreover, different structures are stably connected, and the service life of a device is prolonged.
A vibration exciter with elastic brackets, comprising a cavity cover (1) and a vibration seat (5), wherein support seats are symmetrically arranged on two sides of the cavity cover (1), elastic brackets (3) are arranged on inner sides of the support seats (2), and a support plate (4) is fixed between the elastic brackets (3);
