Tech nothing - if I couldn't get to the power I'd tape an acoustic tile to the thing and drape the whole mess with a blanket. There's a reason most fire alarms in the US go off when disturbed, and are loud enough to cause hearing damage in an empty room; that's what it takes to fight the inevitable unplugging and silencing attempts aimed at a major safety device.
But the next line is "I hate technology but my husband is an early adopter. He has to have everything first.”, so I'm pretty sure the problem with taking a hammer to the speaker is marital rather than political. This isn't 1984, it's a lesson in how bad design aggravates social friction and personal disagreements.
