A new type of the oscillatory variations of the attenuation coefficient of the longitudinal sound wave was found in zinc in magnetic field up to 23 kG at liquid He temperatures. The oscillations were observed only when the direction of the propagation of the sound wave is parallel to the [0001] axis of the crystal and are qualitatively different from the usual de Haas-van Alphen type oscillations and the giant quantum oscillations. From the power spectrum analysis, it was found that three components are contained in the oscillations, the frequencies of which are very good linear functions of the angle between the magnetic field and the [0001]axis. While the amplitude is rather insensitive to temperature, it is an increasing function of the frequency of the sound wave approximately obeying the law f312 between f= 10 MHZ and 90 MHz.
