发明名称 Submersible personal stereo system
摘要 A waterproof pouch to house a personal stereo cassette tape player or radio electrically connected by means of a retractile cable to a pair of waterproof headphones. The waterproof pouch has a closure enabling the pouch to repeatedly be hermetically sealed and reopened. A tubular belt loop is attached to one side of the pouch and secures a belt and buckle combination which fastens around the user's waist. A connector permanently and hermetically secures the electrical cable extending from the exterior to the interior of the pouch. The electrical cable in a coiled retractile form extends from the connector and splits into a Y-shape with both legs electrically attached to the waterproof headphones. Both waterproof headphones consist of a rigid disc with a waterproof earphone mounted on one side and a bracket mounted on the opposite side such that an elastic headband extends through the bracket. The headband is adjustable in length and secures the headphones to the user's head. Both waterproof earphones have pliable sleeves which form a hermetic seal with the user's ear canal to prevent water from entering the ear canal and disrupting the audio program heard by the user. A thin plastic membrane is positioned behind the diaphragm of the earphone to waterproof the earphone when not positioined in the user's canal. This invention enables the user to listen to a high fidelity stereo audio program while active in the water.
