Abstract

An earplug-type earphone is disclosed including: an earplug (10) for producing sound and an elastic support (30). The earplug (10) includes a front housing (200) and a rear housing (500) connected in that order. The elastic support (30) is positioned on an outer side of the rear housing (500). When the earplug (10) is inserted in the external auditory canal, the elastic support (30) is pressed and deformed and then applies resilience to the helix, by which the earplug can be stably positioned in the external auditory canal.
