Description

  The present invention relates to a wearable speaker device, and more particularly, to a wearable speaker device that is used by a listener attached to a portion other than an ear.

  Some sound output devices such as a speaker device are incorporated in a display device such as a liquid crystal television. However, the built-in speaker devices often have a small diameter, so that a sense of reality is often insufficient because a large volume cannot be obtained. In order to obtain a sense of reality, it is common practice to use an external large-diameter speaker system, headphones, and earphones (see, for example, Patent Document 1).

The large-diameter speaker system has the advantage that a plurality of viewers can view simultaneously, and the headphones and earphones can only be viewed by one viewer per device, but the effect of blocking surrounding sounds There is an advantage that an immersive feeling can be obtained.
However, on the other hand, viewing with a large-diameter speaker system may cause discomfort to unviewed people and the neighborhood due to the loud volume when obtaining a powerful sound. And restrictions often occur. In addition, viewing with headphones or earphones has a problem that surrounding sounds cannot be heard, a sound image is localized in the head, and a feeling of fatigue is felt due to long-time use.

  In order to eliminate the above-mentioned disadvantages of the large-diameter speaker system, headphones, and earphones, a speaker that is used by a listener attached to a portion other than the ear, that is, a wearable speaker device, can be considered.

  Patent Document 2 discloses a neck-worn type wearable speaker device that can be necked in a non-contact state with a listener's ear. The wearable speaker device includes a frame having a curved portion in contact with the back of the listener's neck, and speakers provided at both ends of the frame so as to face the curved portion. When worn, the speaker is located below the listener's chin.

  Patent Documents 3 and 4 disclose wearable speaker devices that have a neck hanging portion that is hung from the back of the listener's neck toward the front, and speakers are provided at both ends of the neck hanging portion. In this wearable speaker device, the right ear speaker is positioned on the right shoulder and the left ear speaker is positioned on the left shoulder when the neck portion is hung on the listener's neck.
