Several ways. They're actively looking into health sensor integration, with third party (and their own) devices, medical records, and with the Apple Watch as a continuous sensor. That's a huge market, even more lucrative than smartphones.
Second, they're better poised than anybody in this IoT thing, with their home automation platform.
Third, they are entering the living room, starting with the speakers, tv, etc. When they get serious with this (especially since they also combine it with their home automation) they'll have another nice market to tap.
Fourth, they've long since licensed Car Play, and they also have their own autonomous car project under continuous development. Whether in partnership with a car company or on their own, they can do quite well with e.g. their own electric city car.
Fifth, they also work heavily (and have made acquisitions etc) in AR / VR technology. If they put out some device, it wont be a prototype for enthusiasts like the one's we've seen, it will sell like crazy.
What other consumer electronics company is doing anything innovative?
It instead has everything to do with the fact that high end consumer electronics is only so big of a market, and is one that Apple has almost entirely tapped out.
Apple won the market, overwhelmingly so. But they can't win twice as hard, when they've won already as much as they can.
Among other things, people buy Apple so that they won't be seen buying something more viable.
