The present application relates to the technical field of loudspeakers, in particular to a loudspeaker height-adjusting mechanism. The loudspeaker height-adjusting mechanism comprises a mounting bracket, a housing, a loudspeaker and a driving assembly. The mounting bracket is accommodated in the housing; one end of the mounting bracket is used for supporting the loudspeaker, and the other end of the mounting bracket is connected to the driving assembly; the driving assembly drives the mounting bracket to move up and down in the housing; at least two first guiding units are disposed on the mounting bracket, and at least two second guiding units are disposed on the housing; the first guiding units are arranged along the circumferential direction of the mounting bracket; the second guiding units are arranged along the circumferential direction of the housing; the first guiding units are configured to move up and down relative to the second guiding units when the driving assembly drives the mounting bracket to move up and down in the housing. According to the present application, guiding units mating with each other are arranged on the mounting bracket and the housing respectively, so that the guide in a loudspeaker height-adjusting process is realized, a shaking phenomenon in the loudspeaker height-adjusting process is weakened, and noise is reduced.
