<P>PROBLEM TO BE SOLVED: To pick up performance sound of the violin with enough timbre and sound volume without restricting the performance of a player even when performing with other instruments and completely pick up resonance sound of a body of the violin with a certain level regardless of the interval, and to suppress friction string noise or the like by a violin bow effectively. <P>SOLUTION: A miniature microphone 4 such as an omnidirectional condenser microphone is set in a body 2 of the violin 1 or the like, and sound holes 3A and 3B of the violin 1 are covered with soundproof materials 5, 6 and 7, so as to pick up the resonance sound inside of the body 2 while soundproofing inside of the body 2 with the soundproof materials 5, 6 and 7 against the friction string noise and return sound by the bow. Also, the friction string noise or the like by the bow is picked up to be suppressed by opening a part of the sound holes 3A and 3B without completely covering the holes as necessary. <P>COPYRIGHT: (C)2008,JPO&INPIT |
