That delicate music box can get loud when you plug it in.
This instrument is played just like the 17-note treble Kalimba, but it lacks the resonant box. Consequently, it sounds even more like an antique music box than does the treble kalimba. The small sound board is well-suited for small hands or children. The small board also permits using the right index finger up-stroke method typically used in mbira playing. A nice trick to increase the volume is to hold it against a window or a table as a sounding board.
With the electric pickup added, you can plug in to an amplifier and be as loud as any guitar or drum.
