The HTC Surround was not the most successful Windows Phone, and may in fact have been the least, using its bulk for speakers instead of the more useful keyboard and with the Zune media player not even supporting landscape mode fully.
It seems however HTC has not let the idea die, and has been working on more designs for the smartphone with speakers.
Above is a version with retractable landscape speakers, and to the right is a more simplistic version which merely separate the speakers by using a kick stand, and rely on echoes to induce audio separation.
The designs were revealed from a patent application from Q1 2011, after the release of the HTC Surround.
WindowsPhoneDaily notes that with HTCâ€™s purchase of Beats they have clearly not let go of their music market aspirations, so who knows, maybe a Surround 2 will one day hit the market after all.
