求翻译：以1117芯片为主要的电压转换和稳压模块，实现的无线对讲系统，达到的性能指标是在空旷地可以实现小于50m的语音信号的无线传输。是什么意思？

1117 chip as the main voltage converter and voltage regulator module, wireless intercom system, to achieve the performance indicators in the open can be less than 50m of the speech signal of the wireless transmission.

In 1117 for the major chip converts the voltage and voltage regulator modules for the wireless intercom system, and the performance indicators are in the open in less than 50 M can be achieved by the voice signal wireless transmission.

Take 1117 chips as the main voltage transformation and the constant voltage module, the realization wireless to speaks the system, achieved the performance index is may realize in the open territory is smaller than the 50m pronunciation signal wireless transmission.
