Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of loudspeakers, and in particular relates to a loudspeaker volume optimization method based on an improved artificial bee colony algorithm. Background technique [0002] The loudspeaker is a very commonly used electro-acoustic transducer device. It is the weakest device in electronic components and the most important device for sound effects. Speakers come in many varieties and vary widely in price. Audio electric energy makes its paper cone or diaphragm vibrate the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. Nowadays, people have higher and higher requirements for mobile phones and other electronic devices. Therefore, it is of great significance to design an efficient optimization algorithm to optimize electronic components such as speakers. [0003] The optimization design problems of electromagnetic devices usually have the characteristics of multi-...
