The invention provides an artificial cochlea implant. The artificial cochlea implant comprises a decoder, the decoder comprises a titanium shell, a single rectangular communicating vessel is arranged in a middle path in the titanium shell, a PCBA circuit board is arranged in the titanium shell, and the single rectangular communicating vessel is electrically connected with the PCBA circuit board to achieve the shortest path. According to the artificial cochlea implant provided by the invention, on one hand, a single communicating vessel middle path layout design and an optimized electrical connection mode are adopted, the process difficulty is greatly reduced, and the production cost is reduced; on the other hand, the titanium shell is internally provided with the groove for placing the communicating vessel, and silica gel is packaged on the outer shell of the double-layer titanium shell, so that the implant has enough impact strength.
