Abstract

The invention discloses a loudspeaker system and a low frequency control method of the loudspeaker system. The loudspeaker system includes a DSP control module, at least one first loudspeaker and at least one second loudspeaker. According to the invention, the DSP control module is used for receiving sound signals of an external device and transmitting the sound signals to a first sound signal path and a second sound signal path, processing the first sound signal, duplicating and sending the processed signal to the second sound signal path, then sending the first sound signal to the first loudspeaker and the second sound signal to the second loudspeaker respectively. After processing of the DSP control module, to a certain extent, sound wave phase positions of two loudspeaker arrays where no sound is required are counteracted, and sound wave phase positions of two loudspeaker arrays where sound is required are superposed.

Description

technical field [0001] The invention relates to a loudspeaker system and a method for controlling the low frequency of the loudspeaker system. Background technique [0002] The middle and low frequency sound waves of the speaker have greatly exceeded the size of the original speaker due to their wavelength, which causes the direction of the low frequency sound waves to be 360-degree non-directional when radiated. The above will undoubtedly cause the place where the sound needs to be obtained to get the sound, and there is also sound in the place where the sound is not needed, causing harmful radiation and leakage of sound waves. Contents of the invention [0003] The object of the present invention is to provide a loudspeaker system and a method for controlling the low frequency of the loudspeaker system. [0004] According to one aspect of the present invention, a speaker system is provided, including a DSP control module, at least one first speaker and at least one seco...
