Receiver device

A receiver device capable of switching between (i) an air conduction receiver function for causing a user to receive a phone call by air conduction and (ii) a bone conduction receiver function for causing the user to receive the phone call by bone conduction, comprising:

• a receiver member which sets the receiver device to a state where the user can receive the phone call by use of the air conduction receiver function or the bone conduction receiver function, in a case where the user brings the receiver device into contact with a vicinity of a user's ear;
• and
• a receiver control section including:
• a contact region specifying section which specifies a contact region of the receiver member which region is in contact with the user, while the receiver device is being set, by the receiver member, to the state where the user can receive the phone call;
• and a receiver function switching section which switches to one of the air conduction receiver function and the bone conduction receiver function which one is associated with the contact region specified by the contact region specifying section.
