DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headphone connected to a headphone terminal of audio equipment such as a portable cassette player and a CD player.

[0002]

2. Description of the Related Art Conventionally, when a headphone is connected to a headphone terminal of an audio device, the volume of the audio device is directly transmitted to the ears from a headphone body covering both ears as it is.

[0003]

Since the conventional headphone covers both ears and listens to the sound emitted from the audio equipment, even a loud sound does not disturb the surroundings, so that the sound is heard without being noticed, resulting in hearing loss. There was a drawback that it was easy to become.

The present invention has been made in view of the above-mentioned conventional drawbacks,
It is an object of the present invention to provide a headphone capable of automatically displaying and alerting a user when a sound volume higher than a predetermined value that is likely to cause hearing loss is output from the headphone main body.

The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above object, the present invention provides a connection cord connected to a headphone terminal of an audio equipment such as a portable cassette player or a CD player, and a head connected to the connection cord. In a headphone composed of a horn body, a headphone is formed by attaching a volume detection indicator for displaying when the volume from the headphone body becomes a predetermined value or more to the connection cord or the headphone body.
