Simple, small, experimental free app to boost your speaker or headphone sound volume. Useful for movies, audio books and music.
USE AT YOUR OWN RISK. Playing audio at high volumes, especially for a prolonged amount of time, can destroy speakers and/or damage hearing. Some users HAVE reported destroyed speakers and earphones. IF YOU HEAR DISTORTED AUDIO, LOWER THE VOLUME (but it may be too late).
By installing this application you agree that you will not hold its developer responsible for any damage to hardware or hearing, and you are using it AT YOUR OWN RISK. Consider this to be EXPERIMENTAL software.
Not all devices support this software. Try it and see if yours works.
NOTE 1: This does not work on Android 4.2.1 and higher devices, due Google throttling the audio equalizer: https://code.google.com/p/android/issues/detail?id=41166
NOTE 2: This is NOT for adjusting the speakerphone volume in phone calls (that has its own boost, I think), but for adjusting the volume of music, movies and apps.
NOTE 3: Users who complain that this does not boost bass are right. In order to mitigate (but not remove!) the danger of damage to small speakers, there is no boost in the lowest frequency range, and there is also less boost in the highest frequency range. If you go to the Settings and uncheck Non-uniform boost, you get an across-the-board boost, but that's much more dangerous to your speakers.
NOTE 4: When you set the boost to zero, Speaker Boost will be off. The notification icon is just for ease of launching. If you don't like seeing the notification icon when Speaker Boost is off, just go to Speaker Boost's Settings and set it to appear only when Speaker Boost is running.
简单，体积小，实验免费的应用程序，以提高您的扬声器或耳机的音量。有用的电影，音频书籍和音乐。
使用时需自行承担风险。音频播放高音量，尤其是对于一个长时期的量，可以摧毁扬声器和/或损害听力。有些用户报告摧毁扬声器和耳机。如果你听到音频失真，降低音量（但可能为时已晚）。
通过安装此应用程序，您同意您将不会持有它的开发者负责硬件或听力有任何损坏，并且您正在使用它需要您自担风险。认为这是实验的软件。
不是所有的设备都支持该软件。试试吧，看看你的作品。
注1：这不是在Android 4.2.1及更高的设备正常工作，由于谷歌扼杀了音频均衡器：https://code.google.com/p/android/issues/detail?id=41166
注2：这是不是调节扬声器的音量在通话（即有自己的提升，我认为），但是调整的音乐，电影和应用程序的音量。
注3：谁抱怨说，这并不增强低音的用户是正确的。为了减轻（但不删除！）损伤小喇叭的危险，有在最低频率范围内没有提升，而且也有在最高的频率范围更小的推动作用。如果你去设置和取消“非均匀升压”，你会得到一个全面的升压板，但是这是给你的音箱更危险。
注4：当你设置升压为零，扬声器升压将关闭。通知图标只是为了便于开展的。如果你不喜欢看到通知图标时的扬声器升压关闭时，只要进入扬声器Boost的设置，将它设置为只出现在扬声器升压运行。
