Abstract

The invention relates to a loudspeaker technology, and specifically discloses an active sound box with multiple digital signal processors (DSPs). The active sound box with the multiple DSPs comprises the following modules which are successively arranged according to signal flow: a signal input module, a digital audio processing module, a power amplification module, a speaker module, and a sound box control module. The signal input module is used for receiving audio signals input into the loudspeaker and transmitting the audio signals to digital audio processing module; the digital audio processing module comprises multiple series-connected sound effect processors, and the audio signals processed by the digital audio processing module, after being subjected to amplification processing of the speaker module, are transmitted to the speaker module for restoring to sound; and the digital audio processing module also comprises the multiple DSPs which are connected in series according to the signal flow. An initial DSP is connected with the signal input module, a last DSP is connected with the power amplification module, the last DSP is integrated with a DAC, and the multiple sound effect processors are distributed to the multiple DSPs according to the signal flow.

Description

technical field [0001] The invention relates to loudspeaker technology, in particular to an active sound box with multiple digital signal processors. Background technique [0002] The active integrated speaker (in this technology, the speaker and the speaker mean the same thing) refers to a speaker that integrates a DSP module and a power amplifier module. In order to realize the rapid debugging and correction of the speaker system, multi-layer sound effect processing can be set in the input processing part of the DSP module, for example, including speaker layer DSP processing (for the speaker itself), array layer DSP processing (for a group of speakers) and system layer DSP processing (for the entire speaker system), and then through the control host, the speakers of the speaker system are individually controlled, group synchronously controlled or system synchronously controlled, which simplifies the difficulty of system debugging and shortens the system debugging time. Ho...
