2. Description of the Related Art In recent years, with the development of portable audio equipment, headphones have been widely used. In addition to the conventional type of putting on the head using a band and the type of inserting into the auricular cavity, the earphone type used by hanging on the auricle has also been widely used. FIG. 7 is a perspective view showing the configuration of a conventional ear-hung type headphone.
One end of an ear hook portion 23 is held by a holding portion 22 protruding from an upper part of the main body 21. The ear hook portion 23 extends in a semicircular shape along the outer periphery of the main body 21 and has its own elasticity or not shown. However, due to the spring inside this holding part,
The tip 23 a of the ear hook 23 is urged to approach the main body 21.

At the time of mounting, the distal end 23a is operated with a finger so that the distal end
Is inserted into a constricted portion between the pinna and the head, and the ear hook portion 23 is attached to the back of the pinna by turning the hook portion.

[0004]

However, such a mounting method requires a dexterous operation such as bringing the tip end portion 23a of the ear hook portion 23 to the back of the pinna while opening it with a fingertip.
Since it was a place where it could not be seen, it was quite necessary to get used to it by putting it on your ears by groping.

The present invention has been made to solve the above-mentioned conventional problems and to provide earphone-type headphones which can be worn by anyone without skill.

[0006]
