ios - 如何使用超声波测量两个或多个iPhone设备之间的距离

Question

我想通过使用超声波或其他声音测量来测量两个或多个移动的 iPhone 之间的距离。

这怎么可能呢？

请帮我

问候

Answer 1

iPhone不提供任何具有部分规范的超声功能。您将需要iPhone扬声器产生某种类型的波，并且还需要一个换能器来拾取声波反弹时的声波。

Ultrasound pictures are made from sound waves which are too high pitched to be heard by the human ear. The sound waves travel through your skin and are focused on a certain part of your body by a scanning device called a “transducer.” It picks up the sound waves as they bounce back from organs inside the body.

您可以通过转到 iPhone specs和有关超声的更多信息 here获得更多信息。

也许将来我们可以用我们的iPhone做到这一点？
