A sound transducer or reproductive system has a radiating flexible diaphragm which is attached to a sound radiating board, for example, walls, doors, car body, etc., causing the sounding board to radiate sound. The electromagnetic circuit/driving member is resiliently attached to an armature so that the armature and its driving members react to create motion and also, produce good quality low frequency response or bass tones as well as mid-range and high frequency response. A resilient compressible and expandable means such as pads, springs or clips with an adjustable magnetizable bumper means is interposed between the driving means and the driven means and creates an air gaps which is critical for optimum performance.
A transducer apparatus with means for transmitting electromagnetic sound signals to a vibratory receiving means and with means for transmitting said received signals to a surrounding area, whereby said transducer means has driving means and driven means, with said driving means and said driven means being coupled together in a spaced relationship by a resilient compressible and expandable means with adjustable magnetizable bumper interposed between said driving means and said driven means that allows open separation of said driving means and said driven means about bumper means when said transducer apparatus is activated by a varying electrical signal, whereby vibratory transfer means are attached to the flanges of a magnetizable vented cup shaped baffling structure and extends over the open space of said magnetizable vented cup shaped structure of said magnetically driven means and interposed between said magnetically driven means and a vibratory receiving means with means for attaching said vibratory transfer means to said vibratory receiving means.
A transducer apparatus having a magnetic driving means and a magnetically driven means with said driven means consisting of a magnetizable vented cup shaped baffling structure with flanges extending outwardly from the rim of said magnetizable vented cup shaped baffling portion of said driven element, with said driving means and said driven means resiliently coupled together in a spaced relationship with said driven means having flanges affixed to a vibratory receiving means with fastening means wherein said magnetizable vented cup shaped baffling portion of said driven means is in a spaced relationship with the vibratory receiving means and said vented cup baffling portion of said driven means, when activated with a varying magnetic signal can oscillate and is not in direct contact with said vibratory receiving means, whereby said flanges are an integral part of said driven means and are in solid vibratory contact with said vibratory receiving means, transfers a portion of the magnetically driven force applied from said driven means to said vibratory receiving means, and the other portion that said vibratory receiving means is unable to react to, because of its weight, is radiated to a surrounding area.
