Abstract
A hanging type earphone includes an earphone body and an ear hook. The earphone body has a speaking portion and a first connecting portion thereon. A pair of polygonal prisms is disposed at opposite ends of the first connecting portion. The ear hook is shaped to fit a shape of ears and pivotally mounted to the earphone body for hanging the earphone body on an ear. The ear hook has a second connecting portion shaped as a bridge with a pair of piers disposed there-beneath. The pair of piers each defines a polygonal hole. The second connecting portion rides on the first connecting portion with the polygonal prisms inserted into the respective polygonal holes. A wall of each polygonal hole is at least partially split so that the polygonal hole is enlargeable to enable the polygonal prism to pivot therein.
