ABSTRACT:
An over-the-head face mask is provided with a self-contained microphone, a voice signal modifying device and a speaker for providing a costumed appearance for the individual wearer of the face mask and, in addition, a camouflaging or novelty effect on the wearer's voice. A microphone secured to the face mask is located proximal to the mouth of the wearer and is electrically connected to a voice signal modifier which, in turn, is connected to a speaker. The electrical components are powered by self-contained batteries located within a space provided between the hood portion of the face mask and a fabric liner. The voice signal modifier can amplify or muffle the wearer's voice, shift the frequency of the wearer's voice, produce a monotone voice effect or any other desired camouflaging effect to the wearer's voice. In addition, the face mask can be provided with light bulbs for the fake eyes of the mask. An on/off toggle switch can be electrically connected to the electrical components to switch on or off, as desired, the voice modifying aspects of the present invention. The voice signal modifier can be selectively removed and replaced by a different voice signal modifier in a quick and simple manner. The microphone, voice signal modifier and speaker can be located in a protrusion of the mask, an integral disguise feature of the mask.
