Abstract

PURPOSE:To obtain a speaker with good balanced acoustic characteristics, by taking a paper-made honeycomb core as a core member, laminating a paper- made thin film on both sides of the core member via an adhesives, and constituting a diaphragm plate of honeycomb sandwich construction. CONSTITUTION:A number of hexagonal unit core cells 2 are arranged adjacently to form a honeycomb form in a core 1 bing a core member. The unit core cell 2 is made of thin film, 0.05mm. thick, and 3mm. high, and the minimum diameter of the hollow is 9mm.. Skins 3, 3 in contact with front and rear both sides of the core 1 are paper thin film, 25 deg. SR in knocking degree, 0.2mm. thick and 0.8g/ cm<3>. After sticking the core 1 and the skin 3 as the core member with a two- liquid normal temperature curing type epoxy adhesives 4, the adhesives is cured by press-forming for about 30min, allowing to obtain the diaphragm plate.
