I need a recognisable logo to promote an internal campaign

Industry: Education
Type of logo: Emblem
Brand name/slogan in logo: Student Voice
Ideas for the visual style: Load speaker outline behind the 'Student voice' section in green or black and white?
Things to avoid: The logo must be ethical
Preferred colors: Black and white or green
Extra notes: There are plenty of examples of 'student voice' logo's on google images. I need something original and different, yet stylish and attractive/appealing to many cultures..

This is for a university MBA study that may come into fruition. The attached logo (which should be included) is pretty small. Larger logos may be found on the internet, along with the university's chosen shade of green, should this be used.

'Student Voice' must be used in the logo, and I am open to ideas surrounding a slogan, however this is not strictly necessary.
