摘要： A loudspeaker protective unit for protecting a loudspeaker device against an excessive input current includes a lamp connected in series with the loudspeaker unit. The lamp is housed in a casing exhibiting light-sealing properties formed of an electrically conductive material, and is sealed with a sealant exhibiting a predetermined electrical conductivity. The spacing between lead lines of the lamp housed in the casing is of a preset value. An inert gas is sealed within a main lamp body unit and a preset voltage is applied to the main lamp body unit. When the voltage is applied across the lead lines, an electrical discharge is produced to interrupt the current flowing through the filament so as to prohibit a temperature rise in the lamp.

摘要： A diaphragm for capacitance type loudspeaker is disclosed. The diaphragm uses a conductive high polymer layer as a conductor formed on a high molecular film of PET or the like by treating the high molecular film in a water solvent solution containing a conductive high molecular monomer, a chemical oxidizer and a dopant. The conductive high molecular monomer is selected from the group consisting of pyrrole, aniline, thiophene and derivatives thereof.
