The invention provides a loudspeaker parameter simulation method and device, and relates to the technical field of loudspeakers. According to the loudspeaker parameter simulation method, by building a loudspeaker electricity-voice conversion model, initial parameters are set for the electricity-voice conversion model, a simulation output curve of a loudspeaker is obtained according to the initial parameters and the electricity-voice conversion model, target simulation parameters of the loudspeaker electricity-voice conversion model are obtained by adjusting the simulation output curve, after the output curve of the loudspeaker is determined, the parameters of the loudspeakers are thus determined, pertinence is guaranteed, all parameters of the loudspeaker can be quickly and precisely determined according to the requirement of a client, the research and development cycle is shortened, the research and development cost is saved, and optimal design can be achieved.
