International ClassC09J 005/04Foreign Application Priority Data1990-06-29 JPAbstractA loudspeaker component is bonded to a diaphragm formed of an olefinic resin, by applying an adhesion primer to bonding positions of the component and/or the diaphragm, applying an adhesive to the bonding positions after the primer has cured, and superposing the component and diaphragm. An air curing unsaturated polyester resin is used as the adhesion primer.Field of SearchAt least two liquids rubber and/or resin-containingOf laminae having a different coating on at least two mating surfaces Coating solidified; e.g., by drying, etc., before assembly Polymer derived from polycarboxylic acid or anhydride and polyhydroxy compound wherein at least one of the reactants contains ethylenic unsaturation INTERPENETRATING NETWORK Acoustic transducer Critically defined material or coating Laminated type ELECTRO-ACOUSTIC AUDIO TRANSDUCER | |
