I want to know how to implement FM Transmitter in android app. 我想知道如何在Android应用程序中实现FM发射器。 I want my android phone generate a radio frequency. 我想让我的android手机产生一个无线电频率。 So that I can play music on my phone and transmit it over radio frequency for a near by radio receiver (may be in a car) can amplify to larger audience. 这样我就可以在手机上播放音乐并通过无线电频率向无线电接收器（可能在车内）传输它可以扩大到更大的观众。 Just like TuneAudio on Nokia C7. 就像诺基亚C7上的TuneAudio一样。

2 个解决方案

You would - need an FM Transmitter - that is, the appropriate hardware for generating frequencies in the desired range. 您需要一个FM发射器 - 即用于生成所需范围内频率的适当硬件 。

It is a good thing portable FM Transmitters can be bought from many electronic retailers. 便携式FM发射器可以从许多电子零售商处购买，这是一件好事。 They usually plug into the 2.5mm jack and have a battery for several hours of transmission; 它们通常插入2.5毫米插孔并有一个电池可以传输数小时; there are Android/Phone-specific models as well. 还有Android /手机专用型号。

The Nokia C7 already has the appropriate hardware built in. The standard "Android" does not. 诺基亚C7 已经内置了相应的硬件。标准的“Android”没有。

Good luck :) 祝好运：）

It sounds really complicated, and potentially only available to certain roms, meaning it's probably not something easily achievable on android at the moment. 这听起来很复杂，并且可能仅适用于某些roms，这意味着它可能不是目前在Android上很容易实现的。

Anyway good luck, I'd love to see this happening. 无论如何好运，我很乐意看到这种情况发生。
