Abstract

<P>PROBLEM TO BE SOLVED: To provide a headphone by which a user can listen to stereophonic sounds with presence by adopting the structure of an earlobe into the headphone. <P>SOLUTION: A headphone includes a structure that rear portions of ear pads for supporting a speaker are projected to ear sides, and the projection is suppressed as small as possible in the front portions. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention provides a stereo headphone ear pad with a function similar to that of a person's pinna, thereby enabling stereo recorded sound to be heard three-dimensionally.

Conventional stereo headphones can distinguish left and right sounds. In some surround systems, front and rear sound components can be used to distinguish between the front and rear. However, all of them left a problem with the sense of localization of the sound source, and there was a sense of incongruity that the sound from the front could be heard from above, in the head or behind.

Humans can easily determine the position of a sound source by using functions such as collecting and reflecting with the auricle to obtain a three-dimensional sound. However, in the conventional stereo headphones, the built-in speaker is at a close distance to the ear canal, or the ear pad is uniformly wrapped around the ear pad, so that the three-dimensional effect that should be physiologically created by the auricle has been eliminated. . This is a major factor that makes it impossible to create a sense of reality when conventional headphones are installed stereophonic playback devices.

As shown in the perspective view of FIG. 1, a wall was provided in the rear part of the pad containing the speaker toward the ear side to create the function of the auricle. In addition, the front portion has a structure that eliminates the wall as much as possible.

The headphones of the present invention give the effect of the auricle originally possessed by hearing, which is lacking in conventional headphones. The sound emitted from the speaker is reflected and collected by the artificial pinna to create a three-dimensional sound image. Specifically, the sound from the front becomes a sense of being heard from the front, creating a sense of localization of the sound source, and the sound that should be heard from the front, which was a drawback of conventional headphones, feels uncomfortable as it can be heard from above, in the head, or from behind. Significantly improved. In addition, by creating a sense of localization of the sound source, music can be heard with a sense of reality.

It can be used for all stereo headphones for the purpose of presence and localization.

It is a headphone perspective view from the front. It is an internal view of a headphone ear pad. It is a rear view of a headphone ear pad. It is a top view of a headphone ear pad. It is an external view at the time of wearing small headphones with the left ear. It is a rear view at the time of wearing small headphones with the left ear. It is an external view at the time of sealing type headphones wearing with a left ear.
