Pressure transducer for musical instruments |
摘要 |
A pressure transducer comprised of a piezoresistance bridge on a semiconductor chip is employed as a pressure sensor in musical instruments having an air column through which pressure variations pass in producing sounds, such as in wind instruments and drums. A noiseless voltage preamplifier couples the transducer to a power preamplifier the output of which may then be amplified in a conventional audio amplifier. In the case of a wind instrument, the transducer is mounted between the cup or reed of the mouthpiece and the first key or finger hole, or in the air column in a direction opposite the first key or finger hole in the case of a transverse flute or similar reedless woodwind instrument for direct communication with the air column of the instrument.
