Microsoft’s new Surface Pro 7 is a refinement over previous
models without any significant improvements to the keyboard,
display and the speakers. However, the next-gen Surface Pro,
which could be dubbed ‘Pro 8’, will reportedly have advanced
speakers setup on the back of the type cover.
This is based on a new patent filing by the Redmond, which
points to the integration of louder and advanced speakers into
the Type Cover of Surface Pro.
Spotted by us, the patent titled ‘EXPANDABLE ENCLOSURE FOR
ELECTRONIC DEVICE RESONANCE BOX’ was published by
USPTO on October 31, 2019, and filed by Microsoft in April
The idea described in the patent would definitely make sense
and it could significantly improve the speaker quality of thin
devices like Surface Pro.
“An electronic device, comprises a display and an expandable
enclosure positioned opposite the display. The expandable
enclosure is operable between at least a closed configuration
and an open configuration, such that in the open configuration,
the expandable enclosure defines faces of a resonance box,” the
“One or more speakers include a speaker cone and a drive magnet
assembly. Each of the one or more speakers is positioned on an
outer surface of the expandable enclosure and oriented so that
the drive magnet assembly faces an interior of the resonance
box, and so that the speaker cone faces an exterior of the
resonance box. In this way, the electronic device gains the
benefit of amplifying audio via the resonance box without
adding significantly to the device volume or requiring an
auxiliary speaker system,” Microsoft explained how the device
will function and amplify the audio.
