If you thought the boom-box days ended with the emergence of MP3 players, think again. Samsung has designed an MP3 player with a slide-out stereo speaker system.

The K5 was unveiled by Gee Sung Choi, president and CEO of Samsung Digital Media Business, in a speech to a packed auditorium today at the IFA consumer electronics show in Berlin.

The MP3 player can be turned into a free-standing mini-boom box, enabling users to share their music with others. Stereo speakers are embedded into a panel that slides out from the bottom of the device.

The device weighs 106g and measures 98x48x18mm. It is equipped with a touch keypad and a 1.7in colour Oled display, and will be available in 1GB, 2GB and 4GB versions.

The K5 also comes with an FM radio receiver, photo viewer and clock, and offers 30 hours of playback time. Pricing and availability details were not immediately available.
