If you're just not feeling the game on your smartphone, China's Divoom has something that can help. The ONBEAT-X1 Ultimate Bluetooth gaming speaker sticks to the underside of your device, shaking and vibrating to explosive onscreen action.

Three suction cups secure the palm-sized gaming sound system to the rear of a smartphone, media player or tablet. The 115 x 53 x 85-mm (4.5 x 2 x 3.3-inch) ONBEAT-X1 pairs with the device via Bluetooth 3.0 + EDR, with A2DP support for high quality stereo audio streaming. An included 3.5-mm audio jack also makes it compatible with devices that don't have Bluetooth.

The compact speaker throws out 4 W from its 45-mm micro drivers (which are reported to have a frequency response of 80 Hz - 20 kHz). Divoom claims that its Vibration Bass technology reacts to onscreen gaming action for a more immersive experience. Sadly, despite numerous requests, we've been unable to discover exactly how the tech works but it seems to be based around the company's Passive Oscillation or PO-Bass low frequency enhancement technology.

The ONBEAT-X1 speaker's built-in Li-ion battery is reported to last for up to eight hours between charges, and is recharged via its micro-USB port. It's slated for end of February availability for US$39.90 in either black or white.
