This in%,elitioii relates to improvements in inusical instruments and inore particularly to improvements in vio.Lllls and the invention has as its primarl, object to provide a r, violiii so c6ns,tructed that it will possess a deeper toiie and will deliver solind Nvaves of gretter volui-ie than t',.ie ordin,,try violin. Another 6bject of th,e -'-.i-ivei-itioii is to pi,ovide a violin of Suel-i constriietion that 'Lull io,adv4nta(re will be, taken of the vibratiol-,is of the strino-s of the instrun-ient thereby, as sta @--l ,ted, an@plifyino, the depth aiid volume of the t6n@.

Figure 2 is a side elevation 6f the violin. Fiu-ure 3 is a horizontal sectional view througl-i t,he body of the violin. Figure 4 is a vertical loiio-it-Lidinal seeal view tl-iroug ,5 tion rh the body@'of the violin and a portion 6f the neck aiid. fii-iger board thereof. @ As illustrated in the drawings, the violin comprises, as is usual in musical instruinstruments of this class, a body 1 which is of a resonant wood and which body includes the usual circumferential wall 2, back 3 ,Llid ITiolin belly 4. The neck of the is indie,,ited by the numeral 5 and inounted thereon is the usual finffer board 6 over which the striiias @7 are strun-, from the keys wh,ich are indiI z:l cated by the numeral S. So far as described, the instruiiie.@it en-ibod ino, the invention, does ii.ot d@ifter froin y@ , an ordinary violin, but in order that sound waves iiiay be deepened and amplified, a horn indicated in general by the numeral @9 is arranged -v,,ith-in the body 1 of the violiii, and this horn is syinmetrically arraiaged within the body and has its bell eiid 10 posi- 55 Itloned at the forward end of the body aiid in communicat4@on with openings 11 wliicli are formed,in the eircui-iifereiitial wall 2 of the body at opposite sides 6'L the coniiected end of the neck 5. Except for the fact that 60 the rim of the bell 10 of the hor-.i i@ uiiited@ adhesi vely, or otherwise, to the iiiner sides of the back 3 ard belly 4 and about tl-ie wtlls of the openings 11, the hoi,n is, thi'oual@olit its length, spaced from the bac@, belIT, and 6,5 circum ferential Nvall 2 of the body of the violin except that at its rear end the liorii.is provid ed with an upwardly directed iieci@ indicate d by the niimeral 12, which iieck is fitted through an opening 13 foriiied in the ilo belly 3 near the rear end thereof. The numeral 14 indicates, in gener,-I, t @- ound wave am lifyino- unit con-ipris-.n(- the p usual inetal casing 15 -and diaphrtgin 16 which is iiiounted in the outer wall of the 76 casing' the, casing 6f the unit bein(Y preferably provided with a short ttibular'@extension IT which is fitted into the end of the neck 12 of the horn o that this end o@.' the horn is placed in con-iinunicatioii:with tle i.n- 80 terior, of th4-, casiiig of the sound wave tn-iplif@i ng unit.
