Android控制的蓝牙模块音频控制电路设计
资料介绍
设计了一种基于Android控制的音频控制电路,通过STM32F103C8T6、HC05主从一体蓝牙模块、带输入选择的音量控制器AX2358等关键环节设计,在智能手机中运行APP能实时显示音量和音源接入通道。通过优化整体布局,单独供电,将数字地、模拟地分开等措施,使音频控制电路信噪比超过82dB,实现了高信噪比、低失真、智能控制。
In this paper,an audio control circuit based on Android is designed.Through the design of STM32F103C8T6,HC-05 master-slave Bluetooth module and volume controller ax2358 with input and selection,the APP in smart phone can display the volume and audio access channel in real time,and by optimizing the overall layout,the power will be supplied separately.By the means of digital and analog separation,the signal-to-noise ratio of the audio control circuit is over 82 dB,and high signal-to-noise ratio,low distortion and intelligent control are realized.
