Abstract
A bell device with dual tones for transport vehicles includes a main body, a base, and a trigger. The main body includes two tapering chambers therein and a pinhole located between the chambers. A constant whistling sound is generated for warning approaching cars and pedestrians when wind introduced into one of the two chambers passes through the pinhole. The base is adapted to be fixed on a handlebar and supports the main body, so that the main body is rotatable relative to the base. The trigger includes a flexible operating member which has at least a knocking portion used to beat the main body and induce a warning sound when the operating member is manipulated.
