Abstract
The ear speaker device includes a mount section that is provided with ear-hook sections, and rotation sections that rotate speaker movable sections with respect to the mount section. Tubular ducts are positioned more inside than the ear-hook sections in a natural state. When the ear speaker device is mounted, the speaker movable sections are rotated to the most outside positions. Then, the ear-hook sections are brought into contact with auricle base upper sections, respectively, and the speaker movable sections are rotated inwardly. In this manner, the tubular ducts can be positioned in the vicinity of the external acoustic meatus openings, respectively, of the listener without interfering with auricles and the like.
Claims15
An ear speaker device, comprising:
- a mount section to be mounted on a head of a listener in a manner contacting an upper part of the head, and a left auricle base upper section and a right auricle base upper section of the listener;
- a left speaker section and a right speaker section, each comprising a hollow enclosure to which a speaker unit is attached;
- a left support section and a right support section attached to the mount section to support the speaker section and the right speaker section respectively, so as to position a sound emission surface of the speaker unit of each of the left speaker section and the right speaker section in front of a left external acoustic meatus opening and a right external acoustic meatus opening respectively, of the listener;
- and
- a left tubular duct and a right tubular duct attached to the hollow enclosure of the left speaker section and the right speaker section respectively, and extended so as to allow sound generated in the hollow enclosure of the left speaker section and the right speaker section to reach the vicinity of the left external acoustic meatus opening and the right external meatus opening respectively.
