The invention relates to the technical field of sound box control, solves the technical problem of overcoming the defect of the prior art, and provides a sound box non-contact inductive control system, which has no interference, long service life and low requirement on data band width, and a control method thereof for the current infrared inductive technology. The control method adopted by the invention is that different control functions of the sound box is realized by using a plurality of infrared modules in a non-contact manner; infrared signals are circularly transmitted between the multiple infrared modules; and when one of the modules receives a feedback signal, the infrared module is locked to transmit infrared signals continuously, and sound box function control can be realized according to the control function corresponding to the infrared module. The invention has the advantages that the number of the infrared modules is absolutely not limited, and the installation positions are also not limited, thus a huge design space is brought to designers of sound box industry to lead the products to be more diversified.
