A headphones includes, as the basic configuration, a headband formed into a U shape and headphone cabinets that are supported at both ends of the headband and each include a driver unit. By setting the headband along the top part of the head, the right and left headphone cabinets are brought into contact with and mounted to the ears (for example, Japanese Patent Application Publication No. H08-256390).
At this time, to prevent the mounting position from shifting, a pressure, so-called a lateral pressure, must be applied to each of the headphone cabinets. Usually, the lateral pressure is provided by the elastic restoring force of the headband. Therefore, some user feels oppression pain and sometimes suffers distress when using the headphones for many hours.
To solve this problem, for the headphones described in Japanese Patent Application Publication No. H07-33094, a movable head pad part is provided in the joint part between the headphone cabinet and the headband, and by pressing a part of the top part of the head by means of the head pad part, the positioning of the headphone cabinet with respect to the ear is performed, and the lateral pressure is reduced.
The headphones described in Japanese Patent Application Publication No. H07-33094 incorporates an urging means such as a double torsion spring or a coil spring in the support part of the head pad to give a pressing force to the head pad. Therefore, the construction is complicated, and also the cost is high.
Also, the pressing force of this head pad is designed in the state of being balanced with the gravity, that is, in the state in which the user raises his/her body.
Therefore, when the user uses the headphones while lying down, the headphones shifts and comes off easily.
