Wireless audio company Sonos have promoted a new CEO from within the company to take over from founder John MacFarlane.

The billion dollar a year company is expecting further growth after growing sales 20% in 2016. Sonos is now 15 years old as a company and its wireless music systems are among the most well known, especially within the multi room audio market.

Former Blackberry manager Patrick Spence will take over as chief executive.

The change comes as Sonos readies itself to work alongside the growing number of voice assistants and connected SMart Home technologies such as Amazon's Alexa and Google's Home. 

2017 should see the Sonos music system be able to play music simply by calling out requests for an artist, album or track.
