The invention discloses a method for optimizing the volume of a loudspeaker based on an improved artificial bee colony algorithm, comprising the steps of: building a loudspeaker volume optimization model and initializing artificial bee colony; enabling employed bees to adopt multi-dimension updating and greedy updating strategies to update positions of food sources at positions near h food sourceswith the highest fitness values at present; enabling observation bees to select the food sources through adoption of a roulette algorithm; enabling the observation bees to adopt the multi-dimension updating and greedy updating strategies to update the positions of the food sources at the positions near the h food sources with the highest fitness values at present; when some food source is not updated at continuous several generations, changing the employed bees into scout bees and enabling the scout bees to randomly look for new food sources; repeating the steps until a terminal condition ismet; and outputting the optimal solution. According to the method of the invention, the improved artificial bee colony algorithm is applied to design of the loudspeaker, the advantages of quick convergence rate and high searching accuracy are achieved while a good design effect is obtained, thus usage amount of Fe and the volume of the loudspeaker can be reduced to the greatest extent in short time when the loudspeaker is designed.
