Further, in the device disclosed in Japanese Patent Application Laid-Open No. 2000-188632, an arm for detachably holding a mobile phone is provided as a one-third form, and a hanging device to be hooked on an ear is attached to this arm. Things. In other words, without changing existing mobile phones, hanging devices are attached to the ears via the arm and hooked on the ears, enabling hand-free one-way communication. As another form disclosed in Japanese Patent Application Laid-Open No. 2000-1886862, an arm for detachably holding a mobile phone is provided, and an insert for insertion into an ear hole is attached to this arm. There are things. In addition, the arm is provided with a sound pickup unit that picks up sound from the speaker of the mobile phone, and guides the sound to the ear hole by emitting the sound from the earphone-shaped insert through a sound-conducting air path.揷 The mobile phone is held by inserting the body into the ear, enabling hands-free communication.

Further, as still another form disclosed in Japanese Patent Application Laid-Open No. 2000-1886332, a portable telephone is provided with the above-mentioned hanging tool or insert through a hook-and-loop fastener, an adhesive tape, or a fastening band. Others attach their bodies and hang their hangers on their ears or insert inserts into their ears to allow for hands-free communication.

The portable telephone disclosed in Japanese Patent Application Laid-Open No. H10-304032 is a type in which a cord is pulled out, earphones are attached, and hands-free.

In addition, those disclosed in Japanese Utility Model Registration No. 3 037 744, and those disclosed in Japanese Patent Application Laid-Open No. In the case of mobile phones, the distance between the ear hole and the audio output unit of the mobile phone tends to be larger than when the hand is held by hand, and the audio output unit of the mobile phone may differ depending on the size of the ear depending on the person. There is a problem that it is difficult to hold the position of the ear hole with high accuracy and that the sound is difficult to hear. If the volume of the mobile phone is increased as a countermeasure, the sound will leak to the surroundings, causing problems such as disturbing the surroundings.
