<P>PROBLEM TO BE SOLVED: To provide a portable terminal device that allows a user to use both modes through the use of one oscillator, i.e. a mode for generating air-transmitted sound and a mode for transmitting sound by transmitting an oscillation to a human body. <P>SOLUTION: A portable terminal device 100 includes: one oscillator 123a that is oscillated in response to sound to be output; a resonance part 125 that is oscillated when the oscillation of the oscillator 123a is transmitted to generate air-transmitted sound; a contact part 123 that is oscillated when the oscillation of the oscillator 123a is transmitted, and is brought into contact with a human body to transmit the oscillation to the human body; and changeover means (a projection part 113, a lever 126, an oscillation restriction part 127, and an energization member 128) that performs changeover between a first sound transmission mode for transmitting sound via at least the resonance part 125 and a second sound transmission mode for transmitting sound via the contact part 123. <P>COPYRIGHT: (C)2013,JPO&INPIT |
