mBuild Speaker

The speaker module can play various preset sounds. You can easily store your audio files in the module and play them by invoking corresponding blocks.

Store your audio files in the speaker module as follows:

• Connect the module to a PC.

Connect the speaker module to a PC by using a Micro USB cable. Use the Micro USB port of the module and a USB port of the PC. After the successful connection, the PC displays the disk of the module, and you can open the disk to view the files stored in it.

• Store an audio file.

 Drag the audio file that you want to play by the speaker to the disk. The disk space of the module is limited. It may fail to store a large-size file. It is recommended that you compass a large-size file before storing it in the disk.

• Change the file name (important step).

 Due to hardware design, the speaker module can identify an audio file only by the first four characters (English characters, numbers, or punctuations) of its file name. To play an audio file, you need to change the file name to the special format, that is, a 4-digit combination of English characters, numbers, or punctuations.

The following describes some examples to help you change a file name. The names on the left side are the original ones, and those on the right side are the ones after the change.
