Here is another cool gift idea for trekkies. The Star Trek TNG U.S.S. Enterprise NCC-1701-D Bluetooth Speaker comes with noise emulator, LEDs, and sound effects. It connects to your smartphones via Bluetooth. The unit has a 45mm full range speaker and runs on 800mAh battery.
You get up to 8 hours of music on a fully charged battery. The speaker has engine hum, torpedo blast, warp acceleration and other sound effects.
