Our bike lanes are just a line on the sidewalk and pedestrians routinely walk on them, cross the sidewalk in them without looking, let their toddlers/pets run into them, etc. Also, nobody realizes that a bicycle bell means "someone is coming", so they just ignore it as background noise.
I had to mount an airhorn onto my bike. At least people listen to that, though it's so loud I only use it in emergencies.
I would be worried about a horn like this because if they get startled and move into the path of a car on the actual road, or do any other stupid thing that injures them, you're going to have real problems.
Luckily the actual road is many tens of meters away from the bike path, but you're right otherwise.
