Outer ear structure and outer ear module of recording system
An outer ear structure of recording system includes a base, a first component and a second component. The base includes a first through hole extending along a first axis. The first component is disposed on the base and includes a second through hole corresponding to the first through hole and a recessed area surrounding the second through hole. The second component is disposed on the first component and is offset from the second through hole. An area of the second component is smaller than an area of the first component. The second component includes an inwardly curved side wall facing the first axis.
