Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
The first embodiment is as follows: as shown in fig. 1, a multi-mixing system includes a multi-mixer and a plurality of devices.
The multi-channel mixer includes a Digital Signal Processor (DSP), a controller (MCU), and one or more bluetooth transceivers. The Digital Signal Processor (DSP) is a core module of the multi-channel mixer, and is used to output an audio signal after performing sound effect processing on an input sound source signal. As shown in fig. 2, a Digital Signal Processor (DSP) routes each input audio signal, and each audio processing channel acquires data from one or more input devices according to configuration, performs pre-synthesis audio processing, multi-channel synthesis, post-synthesis audio processing, and then routes to one or more output devices. The Bluetooth transceiver is used for receiving sound source signals or outputting audio signals, communicates with equipment except the multi-channel mixer in a Bluetooth mode, and is connected with the digital signal processor. Each bluetooth transceiver module operates in Master mode and can poll and communicate with 7 devices in Slave mode at most, i.e. 7 devices can be connected. The controller is used for controlling the digital signal processor and the Bluetooth transceiver and is respectively connected with the digital signal processor and the Bluetooth transceiver.
Several devices communicate with the multi-channel mixer in a bluetooth manner to provide audio signals or play sounds based on the audio signals, which are input devices when used for providing audio signals and output devices when used for playing sounds. Each device communicates with any bluetooth transceiver in the multi-mixer. Each bluetooth transceiver in the multi-channel mixer communicates with multiple devices.
As shown in fig. 3, in a field usage scenario, the multi-channel mixer may be communicatively connected to a mobile device, so as to form a multi-channel mixing apparatus, where the mobile device is used to control and configure the multi-channel mixer, and the mobile device may be a notebook computer, a tablet computer, or a mobile phone, which is connected to the multi-channel mixer by a wired or bluetooth manner, so as to configure input devices, output devices, and audio effects of each channel of audio. At the same time, the mobile device also provides a real-time control panel for operation.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
