The honeycomb structure connected by adopting the welding mode has higher connection strength and can be used in special environments such as high temperature and the like. In this embodiment, the welding may be spot welding or soldering, and is selected according to the material or the use requirement of the honeycomb cell 2 in actual production.

Further, the honeycomb structure is formed by splicing corrugated plates 1 layer by layer in a staggered mode, and further the honeycomb cells 2 arranged in an array are formed to form a sound insulation structure.

Further, the corrugated plates 1 spliced with each other are connected by adopting an adhesive connection or a welding mode, and the connection is selected according to the material of the corrugated plates 1 or the use requirement of the honeycomb structure.
