As an analog of the optical frequency comb, the phononic frequency comb has been demonstrated in mechanical resonators recently. In this Letter, we generate the frequency comb in a rhombic micro-resonator with stiffness parametrically modulated by low-frequency pumping. Interestingly, this comb exhi...
