MOBILE TERMINAL AND ITS CONTROL METHOD, STORAGE MEDIUM Russian patent published in 2019 - IPC H04M1/00 

FIELD: electrical engineering.

SUBSTANCE: mobile terminal includes: a housing, a control component, and a piezoelectric excitation component located inside the housing, which creates a piezoelectric effect. Piezoelectric excitation component includes: first excitation source and second excitation source surrounding first excitation source. Control component is configured to control first excitation source to generate first driving force of vibration, and control second excitation source to generate second driving force of vibration, when the mobile terminal is in the handset mode so that in the position where the second excitation source is located, the first vibration wave generated by the first driving force of vibration, and the second vibration wave generated by the second vibration driving force have opposite vibration directions, and the vibration amplitude of the second vibration wave is less than or equal to that of the first vibration wave.

EFFECT: technical result consists in reduction of sound leakage phenomenon.
