Bluetooth Loudspeaker

The description of Bluetooth Loudspeaker

Site Editorial Commentary：Connect your phone with bluetooth speaker, works as remote speaker or megaphone.

Bluetooth Loudspeaker is a user-friendly application that transforms your Android phone into a wireless microphone, seamlessly transmitting your voice to a Bluetooth speaker. Effectively, your Android device functions as a microphone, and the Bluetooth speaker acts as a remote loudspeaker, offering a convenient volume booster or megaphone solution.

*New in release 6.0+ version: Background mode support (Android foreground service) is now available when using the microphone with this app. While using the app with a microphone connected to a Bluetooth speaker, you can exit to the home screen and continue transmitting your voice to the remote speaker. To stop, simply return to the app and click the same button (blueMic / lineOut).

The latest version (5.x) of Bluetooth Loudspeaker includes a built-in MP3 music player, allowing you to sing along to your favorite tunes and output the audio to the remote speaker.

Bluetooth Loudspeaker can also connect to a Bluetooth audio adapter (receiver), which can then be connected via line out to older Hi-Fi systems or amplified speakers, enabling your voice to be output through these systems. (P.S. Please ensure that the Bluetooth audio adapter is connected to an amplifier, not directly to a speaker. Otherwise, the volume output may be very low.)

For optimal voice output quality (with reduced background noise and echo feedback), Bluetooth Loudspeaker supports wired headsets as a voice input source (with both mic and headphone). This allows you to keep your Android phone in your pocket and speak through the wired headset mic, transmitting your voice wirelessly to the remote Bluetooth speaker. Enjoy hands-free convenience! (Requires Android 6.x or above)

Please read the following before downloading this app:
1. This app does not automatically connect to your Bluetooth speaker. You must manually connect your phone to the Bluetooth speaker via Settings->Bluetooth before using the app. Always test the connection with Music 1 or Music 2 at the top to ensure that the voice output is directed to the Bluetooth speaker.
2. This app REQUIRES CONNECTION TO an external speaker to function properly. DO NOT use the phone's internal speaker, as this will produce noisy echo. If you still hear echo, try using another Android device. Some phone models have better noise and echo cancellation capabilities.


Remarks:
1. You need a Bluetooth speaker that can wirelessly connect to your Android device. The maximum loudness depends on the output capaCity of your speaker. To achieve a loud sound with minimal echo, set your phone volume to 90% maximum.
2. To reduce voice echo, ensure that your mouth is not too close to the phone's microphone. Also, choose a device that features both noise suppression and echo cancellation.
3. Bluetooth Loudspeaker also supports line out to amplified speakers (requires a 3.5mm audio cable) or line headphone (please choose a 3-pin jack headphone). This app does not support Bluetooth headsets.
4. If your Android device supports Bluetooth 5.0 or Samsung dual audio (e.g., Galaxy note 9, Galaxy S8+, S9+), it may be possible to wirelessly connect two Bluetooth speakers simultaneously.
