Abstract: The anisotropy of the electromechanical parameters of acoustic waves (bulk, surface and SH waves, as well as Lamb waves) in yttrium and holmium aluminum borates, which are representatives of the single crystals family $RM_3$(BO$_3$)$_4$ (where $R$ = Y, La–Lu; $M$ = Fe, Al, Cr, Ga, Sc) with unique properties of magnetoelectrics and multiferroics with a magnetic ion in the structure has been studied. The analysis of acoustic wave parameters is based on experimentally measured electromechanical constants $C_{ijkl}$, $e_{ijk}$, $d_{ijk}$ and $\varepsilon_{ij}$.

Keywords: crystals with the structure of oxyborates, acoustic bulk waves, surface waves, Lamb waves.
