Second generation electro-acoustics reed for wind musical instrument, has sensor with optimal sensitive axis inclined towards opposed edge to sound source, where sensor is connected to amplifier delivering its energy to sound source

摘要

The reed has an oscillating loop with indirect Larsen effect having low pass filter (F1), resistor and capacitor (RC) filter (F2), an impedance adaptation resistance (F3) and an acoustic conduit (4), which leads an opening in which a wind musical instrument is placed. A microphonic or pressure sensor (1) has optimal sensitive axis inclined towards an opposed edge to a sound source (3). The sensor is connected to an amplifier (2) e.g. class A, AB or B integrated audio amplifier, delivering its energy to the source. The source is placed against the conduit prolonged by the instrument`s body.
