The sound of the cello is played by the bow, and the vibration generated is transmitted to the panel via the bridge. The panel transmits the entire vibration energy to the upper and lower areas of the panel through the bassbar, and then the sound column is transmitted to the back plate. 

After the resonance, the sound is sounded by the F hole, and the tail needle that the cello leans on the ground is also transmitted to the vibration response of the partial bowstring.

Therefore, there will be a dedicated playing platform for the cello tail stick when playing on the stage. The mini horn is the reduced version of the playing platform. We not only reduce the size, but also introduce the acoustic reflection concept design, so that the sound waves are repeatedly in the mini horn.
