The main components of the tensor of the moduli of elasticity and the piezomodulus have been measured in monocrystals of the ferroborate HoFe3(BO3)4. The spin-dependent contributions to sound velocity, dielectric permeability, and piezoelectric response in the antiferromagnetic state were studied. The parameters of magnetoelectric and magnetoelastic interactions in an easy-plane magnetic-ordering phase have been defined. A phenomenological interpretation of observed effects is given.
