N2 - Quantum Spin Hall Effects(QSHE) underpins most of the design in topological insulators. The intrinsic spin-0 of the phononics, yet, continue to be the main barrier in designing acoustic topological insulators. Previous research proposed a solution using external fields such as clockwise and counter-clockwise circulating fluids to create artificial acoustic spin-1/2 states. Most recently, several papers provided ideas based on forming two pairs of degenerate Bloch modes in phononic crystals by tuning the filling factor of the honeycomb lattice. In this work, we introduce a new way to form a phononic double Dirac cone based on the idea of 'zone folding'. By simple modifications of the geometry, topological protected bulk band gaps can be opened and a helical edge channel can be realized.
