Change audio output device for Android 4.4.2 (KitKat)?

I would like to know whether it is possible to select the device via which audio is output for Android 4.4.2 (KitKat). I just had the plan to receive the radio via my old Huawei P6, since only the FM radio can receive it, and then output it via my Bluetooth speaker. However, I have to connect headphones so that they act as an antenna. So the sound only comes from the headphones and not from my Bluetooth speaker. Is there such a setting in this Android version to select the output device or maybe an app that can do that?

But connected differently, you also need an antenna.

Or the plan. Use the antenna from the old Huawei.

Does not work either. The connection is already used by the listener.

Buetooth is rather not suitable for transmitters.
