Abstract

The invention discloses an audio frequency controlling device and method. The device comprises a shunting module, a code modulation module, a central processing unit, a digital-to-analogue conversion module and an audio output module, wherein the shunting module is used for sending an audio file obtained through shunting to the code modulation module; the code modulation module is used for performing code modulation treatment on the audio file and sending an obtained audio signal which is suitable for voice channel transmission to the central processing unit; the central processing unit is used for decoding the audio signal and sending decoded audio data to the digital-to-analogue conversion module; the digital-to-analogue conversion module is used for performing digital-to-analogue conversion on the audio data and sending the converted audio conversion data to the audio output module; the audio output module is used for saving the audio conversion data and playing voice by utilizing the audio conversion data, so that the central processing unit can treat and control the playing of the audio file.

Description

technical field [0001] The present invention relates to the field of media playing, in particular to an audio control device and method. Background technique [0002] With the rapid development of light-emitting diode (Lighting Emitting Diode, LED) display screens, advertisers or other users no longer meet the requirements of single-screen displays for LED display screens, and the demand for audio is also increasing. How to integrate audio and video to provide better advertising services is an urgent problem to be solved. [0003] In the current voice control system, please refer to the application block diagram figure 1 , is a structural diagram of a control system with a voice broadcast function in the prior art, including: a micro control unit (Micro Control Unit, MCU) processor, a digital-to-analog conversion module, an LED driver display module and a voice input and external module, wherein, The MCU processor will process the font data obtained from the upper computer...
