Lost black portable Bluetooth speaker near tide pools on the Oregon Coast beach.

I lost my black Portable Bluetooth speaker while walking on the beach at the Oregon Coast last weekend. It happened around 3 PM near the tide pools. I had it attached to my backpack, but I suspect it fell out when I stopped to take some pictures. It’s not a high-end model, but it has some sentimental value and I would appreciate it if I could get it back.
