是否有可能控制耳机插孔的在Android上的输出电压？ [英] Is it possible to control headphone jack's output voltage on Android?

问题描述

我玩的一些传感器，这些都使得要在手机的耳机插孔中。在iPhone或特定的Andr​​oid手机（银河III为例）传感器的使用是没有问题的，但在其他Android手机（比如Nexus S的，的Nexus，...）输出电压低...

I am playing with some sensors which are made to be used on cell phone's headphone jack. Using sensors on iPhone or specific Android phones (Galaxy III for example) is no problem, but on other Android phones (for example Nexus S, Nexus, ...) output voltage is to low...

任何机会可以利用软件解决方案来控制输出电压是吗？

Is it by any chance possible to control output voltage using software solution?

推荐答案

除了提高音量（这也将提高对音频插孔的放大器），没有一个简单的基于软件的解决方案，以提高电压音频插孔手机。这就需要你以root设备并进行更改音频驱动程序。

Aside from "raising the volume" (which will also raise the amps on the audio jack), there is no easy software-based solution to raise the voltage of the audio jacks on a mobile phone. This would require you to root the device and make changes to the audio drivers.
