HIGHLY SPECIFIC SOURCING

I need two things:

1. A spare strap like you'd get for a digital camera, the kind with a tiny, thin side that you loop through a small projection on the camera to secure the rest of the strap with

2. A strap with the sort of plastic clips on the ends that secure such as a fanny pack or backpack belly strap

Where would I go to get these? I suspect

1. An electronics store, maybe?

2. Sports Basement or some other such outdoor-adventure supply shop

Please confirm or deny. If you have other ideas, too, let me know. I'm basically trying to think of an easy way to hang a portable speaker from my neck while I ride my bike around town, because I'm tired of not having music while I do it, but I don't want to put headphones on because I would like to remain alive and intact.
