## 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.

## Claims

### Claim 1

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

### Claim 2 (depends on 1)
