基于nRF24Z1的无线数字音频模块设计

Design of Wireless Digital Audio Module Based on nRF24Z1

为了解决无线模拟音频信号传输中音质差、功耗大的问题,提出了一种基于nRF24Z1的低功耗高保真无线数字音频传输模块的设计方案。首先本文给出了系统的整体结构框图,然后详细介绍各部分的软、硬件设计方法。实验结果表明:该方案可有效地提高音质、降低系统的功耗,可以连续工作20小时以上,满足设计要求。

In order to solve the poor timbre and large power consumption of the wireless simulative audio transmission,a low-power and Hi-Fi wireless digital audio transmission module based on the nRF24Z1 is designed.At first,This paper gives the overall structure picture of the system.and then describes in detail various parts of the hardware and software designs.The experiment results show that the scheme is effective in reducing system power consumption and improve audio level,could work continuously for 20 hours above,and thus meets the design requirements.
