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.

Claim (Index 4):
The earphone according to  claim 3 , wherein\n the nozzle portion of the housing is formed in such a pipe shape that the one side of the diaphragm of the electrodynamic speaker unit is able to be directly viewed at least from an end portion of the nozzle portion through an acoustic path formed inside the nozzle portion and the first acoustic space.
