card reader speaker

Product Detailed Description

A folded card speaker that opens into a small sound box is the kind of promotional item people keep on a desk long after the event. Slip it into a shirt pocket, unfold it, and the driver fires upward while a memory card plays straight through, with no pairing step in the way.

The rigid card body has a hinged spine, a small full range driver and a rechargeable cell tucked into the base. Buttons for track skip and volume sit along one edge, and a short cable or socket handles charging. Printed covers and themed artwork dress up the flat pack for corporate sets, conference bags and holiday mailers.
