Then there you have the seed for an answer to your question. To keep the vibration at his level quartz has to have a continuous source that keeps it vibrating. The SiO2-structure will transfer the vibration from the point of entry in the crystal lattice through the lattice according to the anisotropic, in this case trigonal, nature. It will not sustain this vibration without external inducer.
