Is my speaker broken? (Sony SRS-XB12)

My speaker is acting weird. I can’t get it to turn off. The blue light blinks 3 times and then goes solid for about 30 seconds before blinking again along with a little “boop” sound. It won’t connect, it’s not saying the battery is low. It has a reset button, and an option to hold down the power and - volume button to initialize. I did both nothing happened.
