Therefore, there have been the following problems in the past.
(B) Conventional headphones have a sound source in the axial direction connecting both ears, and the central direction of sound pressure and the axis connecting both ears are on the same axis, so it feels natural sound spread It is often difficult to get a sense of reality.
(B) In conventional headphones, since the speaker unit is in contact with or too close to the ear, a sound field is formed with the inside of the head limited, and it is difficult to feel a natural sound spread, and it is often difficult to obtain a sense of reality.
(C) Conventional headphones may feel a feeling of pressure or discomfort caused by the speaker unit coming into contact with or too close to the ear, fatigue due to prolonged use, or discomfort that makes the ear crawl or hurt. .
(D) Conventional headphones have a sanitary concern due to attachment of waste products when the speaker unit is in contact with the ear.

(G) When combined with a different application such as (Patent Document 1), the range of use tends to be limited mainly to the other application, and thus there are many cases where the versatility is poor.
(H) In general, stationary speakers naturally require a fixed space for placing the speakers. The same applies to small speakers that are said to be portable and portable.
Therefore, for example, even when a portable sound reproducing device is put in a pocket and music is reproduced with a portable speaker, a place for placing a table or the like is required nearby. If there is no table nearby, you must hold a portable speaker in your hand, which is inconvenient. Similarly, a stationary speaker unit having a configuration in which two flexible arms are connected to one pedestal portion and a speaker is connected to the tip of each flexible arm requires a place for placement. Furthermore, the stationary speaker is difficult to hear unless the volume is increased when the distance from the speaker unit to the user is long, and there is a problem that the sense of reality is lacking when the volume is decreased.

When there is no place, the user has to hold it in his hand, but in the present invention, since the music can be viewed with the base portion on the neck, it is necessary to care about the installation location. You can enjoy listening to music, watching TV, and other media anytime, anywhere.
(I) In the present invention, the speaker unit is fixed to the neck as a method of fixing the speaker unit, so that a sense of incongruity or pressure due to the load weight is reduced as compared with the head fixing. Taking a shoulder car as an example, a parent who has traditionally carried a shoulder wheel can even walk while supporting the weight of the child by holding both legs of the child around his neck, stabilizing the center of gravity, and balancing. It was. Supporting the same weight with the head seems to be quite difficult. There are many other bags and bags that are used on the neck and shoulders, but those that are used on the head are rare. For this reason, it can be said that the neck and shoulder are superior to the head in terms of resistance to load weight and adaptability. In the present invention, for example, when the listener's body is almost horizontal, such as when leaning deeply on a chair and using it in a relaxed posture, the load weight is distributed not only on the neck but also on the chest and shoulders. Also in this respect, the uncomfortable feeling and the pressure feeling due to the load weight are reduced compared to the head fixing. In addition, since the head is not fixed, there is no worry about the hair style being disturbed.
(Nu) In the present invention, the greatest feature is that the speaker unit is hung on the neck, but the position of the speaker unit connected to the tip of the curved base portion hung on the neck is built in the vicinity of the back of the head. In addition, since it is not a fixed system, it does not fall into a forceless situation such as sound can only be heard from behind, and a sufficient sense of realism can be obtained as a front speaker.
