ABSTRACT:
A sound producing helmet for motorcycle riders utilizes a pair of speakers, each secured within an opening in the lining of a motorcycle helmet. A cloth-like screen is secured to the exposed surface of the lining covering the opening. A wire-like screen and a resilient pad may be interposed between each speaker and the cloth-like screen, providing further protection to the active surface of the speaker and the user of the helmet, if desired. Each speaker is connected to a female receptacle secured within openings in the helmet. An extensible cable is provided with a pair of plugs, each adapted to be inserted into the female receptacles and each carrying one channel of a stereophonic audio voltage signal coupled into the cable by utilizing a multi-terminal plug adapted for insertion into a receptacle attached to a magnetic tape playback device attached to the body of a motorcycle.
