1. A sound generating device, comprising:
a housing having a cavity therein; and
a frame fixedly provided in the cavity, a high-pitch sound generator and a low-pitch sound generator are respectively provided on two opposite sides of the frame,
wherein a baffle plate is provided on a side of the housing corresponding to the high-pitch sound generator, and the baffle plate and the housing together form a side sound output port corresponding to the high-pitch sound generator;
wherein the sound generating device module is configured to form a front sound output structure for the low-pitch sound generator; and
wherein the frame and the housing form a first rear sound cavity and a second rear sound cavity isolated from each other in the cavity, the first rear sound cavity is communicated with the low-pitch sound generator; and the second rear sound cavity is communicated with the high-pitch sound generator,
wherein an edge of the frame bends and extends towards a direction opposite to the baffle plate to form a first accommodation groove, and at least a part of a structure of the low-pitch sound generator is disposed in the first accommodation groove;
wherein a through hole is provided at a middle of the frame, a side wall of the through hole bends and extends towards a direction of the baffle plate to form a second accommodation groove, and at least a part of a structure of the high-pitch sound generator is disposed in the second accommodation groove; and
wherein a partition plate is provided surrounding the high-pitch sound generator on a side of the frame facing the baffle plate, and the partition plate separates the cavity to form the first rear sound cavity and the second rear sound cavity;
or
wherein an edge of the frame bends and extends towards a direction opposite to the baffle plate to form a third accommodation groove, and at least a part of a structure of the low-pitch sound generator is disposed in the third accommodation groove;
wherein a mounting hole is provided at a center of the frame, and at least a part of a structure of the high-pitch sound generator is disposed in the third accommodation groove by penetrating the mounting hole; and
wherein a partition plate is provided surrounding the high-pitch sound generator on a side of the frame facing the baffle plate, and the partition plate separates the cavity to form the first rear sound cavity and the second rear sound cavity.
