Embodiment 1

[0044] like Figures 16 to 19 As shown, this embodiment is a control method for an active integrated speaker with a multi-DSP system. The method controls the physical speaker through the control host, and the physical speaker includes signal input modules arranged in sequence according to the signal flow direction. , a digital audio processing module, a power amplifier module and a speaker module, the control host includes a display module, a data module and a network module, and is characterized in that it includes:

[0045] Step 10: Initialize and search for online speakers (online speakers refer to physical speakers that establish a connection with the control panel);

[0046] Step 20: Open or create a new system model, display the system model window on the display interface of the display module, and perform an automatic matching operation, so as to match the online speakers obtained in the above step 10 with those in the current system model that have established a pairi...

Embodiment 2

[0122] The difference between this embodiment and Embodiment 1 is that the physical speaker of this embodiment includes a signal input module 10, a digital audio processing module 20, a DAC 51', a power amplifier module 30, a speaker module 40, and a The speaker control module 90 that controls one or more of the above modules, the signal input module is used to receive the audio signal input to the speaker and transmit it to the digital audio processing module. If the input sound box is an analog audio signal, it needs to be converted into a digital signal by an ADC, and the ADC can be set as an independent device, or set in the signal input module, or integrated into the digital audio processing module.

[0123] like Figure 12 , Figure 13 As shown, the digital audio processing module includes an input processing module and a plurality of output processing modules, wherein the input processing module includes a plurality of sound effect processors connected in series, and e...

Abstract

The invention relates to a sound box control technology, and specifically discloses a control method for an active integrated sound box with a multi-DSP system. The method comprises the steps of initialization, sound box model editing, sound box control parameter (such as DSP data) editing and the like to realize remote control of dispersedly arranged entity sound boxes though controlling a host. According to the invention, one the basis of window type management, a chart type management method is employed, and the whole new idea of a sound box model is adopted for concentrated management of the dispersedly arranged active sound boxes on a computer platform, such that the problem caused by the lagging of software behind hardware development in a conventional active sound box technology is radically solved.

Description

technical field [0001] The invention relates to an active sound box control technology, in particular to a control method for an active integrated sound box with a multi-DSP system. Background technique [0002] In the sound reinforcement system of theaters, auditoriums and other places, in addition to program source equipment, mixers, power amplifiers and speakers, signal processing equipment is generally used. Traditional signal processing equipment, such as compressors, limiters, expanders, etc. that focus on amplitude processing, equalizers, exciters, feedback suppressors, frequency dividers, etc. that focus on frequency processing, and focus on time processing such as Delay, Reverb, etc. [0003] With the introduction of Digital Signal Processing technology at any time, digital audio processors that can realize various signal processing functions have appeared. This is an integrated device with a digital signal processor (Digital Signal Processor) as the core. Compre...
