当应答器进入发射天线无功近场区时（距天线口径表面范围内）,应答器以耦合方式获得能量；将自身编码等信息通过发送天线发送出去

When the transponder telemetry into antenna reactive near-zone (from the antenna aperture surface range),transponder telemetry with coupling way to gain energy,Will their coding information through sending,receiving antenna send out the antenna to signal,the reader to receive the signal for filter and amplification by audio power amplifier amplification,again by the speaker sends out the music sounds.

中文：当应答器进入发射天线无功近场区时（距天线口径表面范围内），应答器以耦合方式获得能量；
英文：When responder come into radio zone, it will get energy by the way of coupling.
