XiaoZhi C3 Shell Base Modified Version v1

Thanks to the original author for the model, but this model is not suitable for the XiaoZhi C3 kit I purchased. The speaker cable is too short and cannot fit the model, as shown in the figure; I swapped and modified the positions of the battery and speaker in the original author's shell base, and optimized the speaker's sound outlet with a circular opening; The main purpose was to solve the problem of the speaker cable being too short to snap into the right slot.
