Loudspeaker (telephone receiver)
Form follows logo

Solution

Simply...  let the shape of the logo define the shape of the loudspeaker.

The product is made of  plastics and combines the bright/dark colors.
Two loudspeaker are integrated in some sort of a telephone receiver which has a connector for smartphones attached to it.
The control of the loudness surely can be adjusted by the smartphone but it might also be possible to use one of the loudspeakers as an integrated control knob (including an on-/off-switch).
