Move somewhere else. Its a public space. Nobody is going to make everyone happy 100% of the time. Or go in the slower/more calming hours. Or get your own private beach.

This just reads as bitching.

Some people get to go to the beach all the time and enjoy having fun there and being social. Not quietly listening to the waves. You want a public beach to be your way, go buy a private beach.

Hey you’re welcome. I really enjoy my Bluetooth speaker at the beach. I play it just loud enough so when I’m sitting in my area in my little tent that I can hear it. If you’re sitting close enough to me to be able to hear your music then you can fuck off.
