The Grove Speaker Plus includes a powerful amplifier driver board, and a speaker. With the onboard potentiometer, you can easily adjust the output volume. You can replace the speaker with other speakers, as it adopts a separate and replaceable speaker design.
The speaker generates different tones, with different input frequencies and is easy to control with the PWM signal. You could create distinctive sound effects, play your favourite songs, or build your own music box with easy coding, or a large number of existing music codes.
Compared to the last version of Grove Speaker, this Grove Speaker Plus has a better quality speaker, with a separate and replaceable speaker design, which enables you to replace it with any other loudspeaker, and you can easily adjust the output volume.
