What is it?<\/p>\n\t\t\t\t\t

Wood, magnets and a touch of aluminum.<\/em><\/h2>\n\t\t\n<\/div>\n
\n \t\t\t

Because I love wood, I built my own ribbon microphone. Not only the body is made of wood, but also parts of the ribbon motor.<\/p>\n\t\t\t\t\t

Lousa is Styrian for ears \u2013 fitting for an instrument whose only job is to listen.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n

\n \t\t\t

The ribbon<\/p>\n\t\t\t\t\t

A wafer-thin, corrugated aluminum foil \u2013 so light that it follows every movement of the air.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

The magnets<\/p>\n\t\t\t\t\t

Two strong magnets hold the ribbon between them. When it vibrates in their field, a tiny voltage is created: the signal.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

The motor<\/p>\n\t\t\t\t\t

The frame that holds the ribbon and magnets in position is partly built from wood.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

The housing<\/p>\n\t\t\t\t\t

A wooden body with a drilled hole pattern through which the sound reaches the ribbon.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n\n<\/div>\n

The microphone in the video is still the prototype. The next Lousa is in the making: its housing is being carved from a single piece of wood on the CNC mill.<\/p>\n\t\t\t\t\t

The first parts are milled \u2013 more as soon as it makes its first sound.<\/p>\n\t\t\t\t\tin development<\/span>\n\t\t\n<\/div>\n
