Aside from what we've heard about the "Siri speaker" before (such as deep HomeKit integration and the ability to control smart home gadgets), today's Bloomberg report says that Apple is placing a heavy emphasis on sound quality.

For Apple, a smart speaker is a long time coming.

As for how Apple's offering might differ from existing smart speakers already on the market, there are rumblings that the device will feature a touchscreen, a design that Apple executive Phil Schiller arguably confirmed just earlier this month during an interview.

The report comes after KGI Securities analyst Ming-Chi Kuo said in May there's a more than 50 percent chance Apple will unveil its Siri speaker at the Worldwide Developers Conference. However, the speaker may not be ready to ship to consumers until later in 2017.

Meanwhile, shares of Apple Inc.

Bloomberg's recent report said the device will have an engraving that will say: "Designed by Apple in California". That would help combat the competitive threat from Google's and Amazon's connected speakers: the Home and Echo mostly don't support services from Apple.

According to the sources, the speakers are powered by the Siri virtual assistant that's available on Apple's phones, tablets, and computers. The manufacturing company behind Apple's AirPods will also be responsible for building out the new speaker.

Apple's Worldwide Developers Conference kicks off June 5. Sources also shared that the speakers are louder and "reproduce sound more crisply" then rivals, and that Apple has considered measuring room acoustic's to adjust sound levels. The Siri speaker reached an advanced prototype stage late past year, Bloomberg News reported at the time.

As with the Echo and Google Home, Apple's device will also help users control their smart home. Last year, Apple opened up Siri on the iPhone to the likes of Uber Technologies Inc. and Facebook Inc., allowing a user to order a ride or send a WhatsApp message with a voice command.
