Abstract

A double-bar violin family without sound post, including a resonance box, with a front plate, back plate and sidewalls, wherein: two upper bars are parallel on the front plate inner wall; two lower bars are parallel on the back plate inner wall; an upper cross groove sits on the front plate inner wall, and forms an upper cross sound tunnel on the front plate inner wall; a lower cross groove sits on the back plate inner wall, and the lower cross groove forms a lower cross sound tunnel on the back plate inner wall. This breaks the shackles of the traditional bass bar and sound post design in resonance box, eliminates sound post in resonance box, and proposes a new improved design, wherein treble register is not bright, and bass register is not sonorous and mellow enough, so the resonance box produces treble, alto, and bass registers with good timbre.
