Abstract: In one embodiment, the present invention is directed to a cheering apparatus, comprising: an effect selector, for selecting a sound effect to be played upon activation; a motion detector, for detecting an acceleration or deceleration by a user's limb; and an audio unit, for playing the selected sound upon indicating by the motion detector acceleration or deceleration of a user's limb. The cheering apparatus may further comprise a handheld casing, for housing at least a speaker of the audio unit. The cheering apparatus may further comprise a connector, such as one or more straps, for directly or indirectly connecting the motion detector to a human's limb. The motion detector may comprise: a conductive weighting object; a flexible conductive element connected at one end to the weighting object, and connected at the other end to a non-conductive chassis; and conductive housing.
