PROBLEM TO BE SOLVED: To provide a vibration device capable of adding functions of reinforcing listenability by transmitting vibration to a human body, even in such an environment as hardly hearing by only an air conduction sound, to a conventional mobile phone, and also capable of reducing parts count and facilitating mounting thereof with a small power consumption.SOLUTION: A vibration device 100 includes: overhangs 102, 103, 104 detachably attached to a mobile phone 500; an abutment (110) arranged at a position where at least a portion thereof can be brought into abutment with a user's ear and/or a human body of an ear periphery; a vibrator (111) face-bonded to the abutment and vibrating at a frequency band of an audible area where vibration is not transmitted to user's hearing organs via a user's skull from the abutment; a drive unit (107) for driving the vibrator; and a connector 106 for receiving an audio signal from the mobile phone and transmitting the signal to the drive uint. |
