Description

  The present invention relates to a wearable speaker device, and more particularly, to a wearable speaker device that is used by a listener by attaching it to a part other than the ear.

  Some sound output devices such as speaker devices are used by being built in display devices such as liquid crystal televisions. However, many built-in speaker devices have a small diameter, and a sense of presence is often insufficient because a large volume cannot be obtained. It is common practice to use an external large-diameter speaker system, headphones, or earphones (for example, see Patent Document 1) in order to obtain a sense of presence.

A large-diameter speaker system has the advantage that a plurality of viewers can view at the same time. In addition, headphones and earphones allow only one viewer to view one device, but the surrounding sound is cut off. There is a merit that a feeling of immersion can be obtained.
However, on the other hand, viewing with a large-diameter speaker system may cause discomfort to people who are not watching or nearby due to the loud volume when a powerful sound is obtained. And restrictions often arise. In addition, viewing with headphones or earphones has a problem in that surrounding sounds cannot be heard, and a problem that a sound image is localized in the head, resulting in a feeling of fatigue due to long-term use.

  As a solution to the above-mentioned disadvantages of the large-diameter speaker system, the headphone, and the earphone, a speaker that is worn by a listener at a part other than the ear, that is, a wearable speaker device can be considered.

  Patent Literature 2 discloses a neck-wearable wearable speaker device in which a neck can be hung in a non-contact state with a listener's ear. This 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 direction of the curved portion. When worn, the speaker is located under the listener's chin.

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