Microsoft patents a high-efficiency portable Speaker

In recent times, Microsoft’s digital voice assistant Cortana is going through a tough time. However, the company is trying its level best to cover this by pushing back to back digital voice assistants to gain some traction. In the enterprise world. Recently, it was announced that the Office had been integration in Surface Earbuds. This shows how desperate the company is.

It is believed that Microsoft is working to create its own Echo-like speaker according to a patent filing. On the other hand, a patent published earlier this year revealed a Microsoft-branded speaker with Teams integration for businesses. Now, another patent filing has surfaced online that revealed the consumer-centric features of the device

In a recent patent, Microsoft envisions a high-efficiency portable speaker, which is designed to produce better sound quality but consumes less power throughout. In terms of design, Microsoft’s patented smart speaker is cylindrical, and it is very similar to the traditional speakers that are currently available in the market.

The Microsoft patent was titled ‘High-efficiency speaker with multi-magnet structure.’ It was filed back in May 2018 but got published by USPTO only on 26th November 2019.

The patent states the following: “In traditional large speakers, flexible, corrugated support called a spider is used to suspend the voice coil in place within a basket housing. In a different variant, the spider can attach to the membrane (e.g., diaphragm) on one side and a basket or magnet on the other side, providing stabilization for the membrane throughout its corresponding range of motion.”

Microsoft explained, “The herein disclosed technology provides an increase in speaker efficiency that may permit mini speakers to be driven with smaller amplifiers without a trade-off in volume or sound quality. This increased efficiency may translate to better sound and/or decreased power consumption as compared to similar-sized speakers that include larger amplifiers and/or speakers that do not utilize a spider to stabilize the membrane.”
