摘要 <p>The sound producing helmet for motorcycle riders utilises 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. Each speaker is connected to a female receptacle secured within openings in the helmet. An extensible cable carries a stereophonic audio voltage signal from a magnetic tape playback device attached to the body of a motorcycle.</p>
