  We theoretically study the Berry curvature of the magnon induced by the
hybridization with the acoustic phonons via the spin-orbit and dipolar
interactions. We first discuss the magnon-phonon hybridization via the dipolar
interaction, and show that the dispersions have gapless points in momentum
space, some of which form a loop. Next, when both spin-orbit and dipolar
interactions are considered, we show anisotropic texture of the Berry curvature
and its divergence with and without gap-closing. Realistic evaluation of the
consequent anomalous velocity is given for yttrium iron garnet.
