Abstract: The present invention relates to a canal type earphone configured such that an outlet for a sound wave to be reproduced is inserted into an inlet of a user's ear canal. The earphone includes an electrodynamic speaker unit configured to electroacoustically convert an audio signal into a high-frequency sound wave containing a band component having a higher frequency than that of an audible band of a human being, thereby emitting the high-frequency sound wave; an electromagnetic speaker unit configured to electroacoustically convert the audio signal into a low-frequency sound wave containing more band components having a lower frequency than that of the high-frequency sound wave, thereby emitting the low-frequency sound wave; and a housing to the inside of which the electrodynamic speaker unit and the electromagnetic speaker unit are attached.

Abstract: There are provided headphones and a speaker unit having proper acoustic properties and exhibiting excellent reproduced sound quality even in the case of providing air holes at a damping member. The headphones include a speaker unit having a diaphragm and a frame supporting an outer peripheral portion of the diaphragm, a housing configured to house the speaker unit, and a damping member made of a material exhibiting air permeability and attached to cover an opening of the frame through which a sound wave emitted from the diaphragm passes and/or an opening of the housing. The damping member has one or more air holes formed by removal of the material forming the damping member. A secondary damping member is attached to an annular edge portion defining each air hole, thereby reducing vibration of the edge portion.
