This article is about a/an weapon in Kamen Rider Fourze.

The Beat Module (ビートモジュール Bīto Mojūru) is the Fourze Module which is equipped on the right leg of Kamen Rider Fourze via the cross-based Beat Switch (ビートスイッチ Bīto Suitchi). The Beat Module resembles a small subwoofer that can produce sonic waves with a range of 20Hz-5kHz and a tweeter with a range of 5kHz-24kHz. A rather hilarious aspect of the Beat Module is that it can behave much like a normal sub-woofer, meaning that electric guitars could be plugged into it.
