A mobile phone and a listening device
Document Type and Number:
Japanese Patent JP6178551
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a portable telephone and a hearing device simplified in configuration.SOLUTION: The explanation of a cartilage conduction function is performed by a display part or a cartilage conduction section in a predetermined time since a power supply switch is turned on, or a time duration after a calling operation section is operated until the other party makes a response, or a time duration from call incoming to a response operation. When the explanation is manually stopped, or it is detected that the cartilage conduction function is normally used, the explanation is stopped, and the explanation is no longer performed. When the portable telephone is tilted rightward, the use of the right corner is guided, and when the portable telephone is tilted leftward, the use of the left corner is guided. There is provided a stereo cartilage conduction section with a through-hole configured so as to be connected to a sound source device whose maximum output to the outside is 500 mVrms or more for obtaining vibration acceleration which is 50 dB or more at the rear side of the tragus in accordance with the input of 200 mVrms.
