3. The audio device according to claim 2 , wherein, before the voice output function of causing the user to hear a voice by the first operation or the voice input function of inputting a voice of the user by the second operation is provided to the electronic device, the personal authentication function for identifying whether the user is a target person of the voice output function or the voice input function by the third operation and the fourth operation is provided to the electronic device.

4. The audio device according to claim 1 , wherein the electronic device stores personal data of the user, and

wherein, in a case of receiving, via the interface section, the authentication instruction signal that is to be transmitted by the electronic device when access to the personal data of the user is required, the hardware processor performs the third operation and the fourth operation.

5. The audio device according to claim 1 , wherein the electronic device performs language learning by using one of the sound emission section and the sound reception section, and

wherein, in a case of receiving, via the interface section, the authentication instruction signal that is to be transmitted before the electronic device performs language learning, the hardware processor performs the third operation and the fourth operation.

6. The audio device according to claim 5 , wherein the electronic device performs one of listening learning by using the sound emission section and speaking learning by using the sound reception section.

7. The audio device according to claim 5 , wherein the electronic device stores personal data of the user regarding the language learning, and

wherein, in a case of receiving, via the interface section, the authentication instruction signal that is to be transmitted by the electronic device when access to personal data of the user is required for performing the language learning, the hardware processor performs the third operation and the fourth operation.

8. A control method for an audio device including a sound emission section which outputs a sound into an earhole of a user, a sound reception section to which a sound from the earhole of the user is inputted, and an interface section which is connected for communication with an electronic device, wherein the control method comprises:

converting a signal received from the electronic device via the interface section into a first sound signal corresponding to a voice or a musical sound, and outputting the first sound signal via the sound emission section,

converting a voice of the user inputted via the sound reception section into a first electrical signal, and transmitting the first electrical signal to the electronic device via the interface section,

converting an authentication instruction signal received from the electronic device via the interface section into a second sound signal having a specific frequency, and outputting the second sound signal via the sound emission section as an acoustic wave for authentication, and

converting an echo wave inputted via the sound reception section and created by the acoustic wave for authentication being reflected inside the earhole of the user into a second electrical signal, and transmitting the second electrical signal to the electronic device via the interface section.

9. A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer in an audio device including a sound emission section which outputs a sound into an earhole of a user, a sound reception section to which a sound from the earhole of the user is inputted, and an interface section which is connected for communication with an electronic device, wherein the program controls the computer to perform operations comprising:

converting a signal received from the electronic device via the interface section into a first sound signal corresponding to a voice or a musical sound, and outputting the first sound signal via the sound emission section,

converting a voice of the user inputted via the sound reception section into a first electrical signal, and transmitting the first electrical signal to the electronic device via the interface section,

converting an authentication instruction signal received from the electronic device via the interface section into a second sound signal having a specific frequency, and outputting the second sound signal via the sound emission section as an acoustic wave for authentication, and

converting an echo wave inputted via the sound reception section and created by the acoustic wave for authentication being reflected inside the earhole of the user into a second electrical signal, and transmitting the second electrical signal to the electronic device via the interface section.
