## Abstract

An audio device includes a sound emission section which outputs a sound, and a sound reception section in which a sound is inputted. The audio device, when an electronic device is connected thereto, outputs to the electronic device unique authentication information acquired in accordance with an instruction received from the electronic device so as to acquire the authentication information.

## Claims

### Claim 1

An audio device comprising:
a sound emission section which outputs a sound; and
a sound reception section in which a sound is inputted,
wherein the audio device, when an electronic device is connected thereto, outputs to the electronic device unique authentication information acquired in accordance with an instruction received from the electronic device so as to acquire the authentication information.

### Claim 2 (depends on 1)

The audio device according to claim 1, wherein the audio device outputs an acoustic wave having a specific frequency and transmits, to the electronic device, authentication information based on an echo wave created by the acoustic wave being echoed in a user wearing the audio device.

### Claim 3 (depends on 2)

The audio device according to claim 2, wherein the authentication information is acoustic properties based on a waveform of the echo wave created by the acoustic wave being outputted into each earhole of the user and reflected in accordance with an inner shape of the earhole.
