That means using the most common type of bell and from my experience the majority of bikes these days come fitted with something like pic related. More common in the past would be something like what you posted (probably less common these days due to being more complicated and costly) that makes a longer ringing sound like a phone instead of a single ding.
Unfortunately I don't have a bell so I can't share my personal experiences, and being a fellow cyclist if I hear someone else's bell I always get out of the way regardless of the sound.
