MAIN NAME CONCEPT:
The name Local Voice is related to the idea of the "loud voice" of people talking about whatever cool thing is happening in the city/neighborhood (that's why "local").
This "voice" is the voice of the people (local "authorities", proud to be recognized as "locals"), that "scream" to the city or to the neighborhood what are the coolest things to do in that area. So this could be considered the "voice" of the city/neighborhood (through its "locals").
We just need an image/symbol to add to our logo "LocalVoice" and not the entire Logo (imagine for example just the symbol next to "Yelp" that looks like a flower more or less; we already have the logo and we just need to add the symbol next to the logo), so don't worry about the logo LocalVoice and work just on the symbol/icon that will go next to LocalVoice.
DESIGN IDEAS AND DIRECTIONS:
We want this work to be the standard symbol of "local map pin" (used in Google Map, Facebook Place, etc.). So this symbol needs to be the base on which start working.
So the basic requirement is to create an icon that merge the idea of "Local" (through the standard symbol of local map pin) with the idea of the "Voice". While we are sure we want the standard symbol of local map pin for the idea of "Local", we are between 2 ideas to add the idea of "Voice".
1) Our first idea was to merge the symbol of local map pin and put inside it the image of a big open mouth that should give the idea of "screaming", then the idea of the "voice". You will find an attachment of what we did.
We are not sure about it, because our result was a kind of ambiguous (it was not immediately clear it was an open mouth when this symbol is in the small version and it's difficult to distinguish the lines).
That's why we started thinking about a second version.
2) This second option would be always the standard symbol of local map pin, merged with the symbol of the megaphone (that should give the idea of "loud voice") [see attached file "ugly_draft_logo.jpg" to just get an idea]. The megaphone is used for example in the logo of the website UserVoice.com (see attachment), but we don't want a stand alone megaphone. We want the megaphone merged into the standard symbol of local map pin (since they have a very similar shape!).
we want you to create this symbol/image = standard symbol of "local map pin" merged with the symbol of the megaphone (option number 2).
However, if you think our first idea of the big mouth open inside the local map pin (option number 1) could be a good one and you feel you can improve it and make it understandable at the first sight, go for it.
But we would like to see especially the idea number 2 (the one of the megaphone).
You can start with both ideas and we'll decide which way to take, based on the results.
