Electroacoustic transducer

Abstract

Abstract PURPOSE: To avoid the disconnection of a lead wire, by adhering then lead wire of the voice coil of a speaker to the diaphragm with a hard adhesive at the area near the voice coil and with a soft adhesive at the fringe area of the diaphragm respectively. CONSTITUTION: For the lead wire 38 led from the voice coil 36, the part 38a is led out in the direction to tangent of the coil 36 and the part 38b is located so as to have the same axial core as the axial core of the diaphragm 20. Then the lead wire part 38a is adhered to the peripheral part 20b of the diaphragm 20 with the rather hard adhesive 44; and the lead wire part 38b is adhered to the part 20b with the softer adhesive 46 than the adhesive 44 respectively. As a result, the wire 38 also moves in a body with the coil 36 having a large amplitude vibration and at the area near the coil 36, and the soft adhesive absorbs the unnatural vibration applied to the fringe area where a minor amplitude vibration is given. Accordingly the unnecessary force is never applied to the bent part 38c of the wire 38 to reduce the occurrence of disconnection of the wire 38. COPYRIGHT: (C)1981,JPO&Japio
