VOICE COIL BOBBIN CONNECTION TO LOUDSPEAKER DIAPHRAGM OF HONEYCOMB CORE SANDWICHED BY SHEETS

摘要

A diaphragm for a flat plate electroacoustic transducer such as a loudspeaker includes first and second diaphragm sheet members having a honeycombed core structure sandwiched therebetween and includes an interconnection between each diaphragm and the piston or voice coil bobbin to avoid shifts and delays in transmitting vibration to each diaphragm and eliminate the tendency to introduce extraneous auditory sounds.
