Electronic apparatus, electronic apparatus control method and storage medium

An electronic apparatus to which an external apparatus is detachably attachable comprising:

• a vibration detecting unit configured to detect vibrations of a plurality of vibration devices provided on at least one of the electronic apparatus and the external apparatus;
• and
• at least one processor or circuit which functions as a controlling unit configured to make the plurality of vibration devices vibrate by using a vibration parameter corresponding to a type of the external apparatus to be attached to the electronic apparatus, and
• wherein the controlling unit controls calibration on vibration parameters for the plurality of vibration devices in order that a vibration amount of the vibration detecting unit is equal to or less than a predetermined threshold.

A control method of a camera body to which an external apparatus which is at least one of a lens unit, a strobe unit, a microphone, a viewfinder unit, a tripod, and a jacket is detachably attachable, the camera body including a vibration device provided on at least one of the camera body and the external apparatus and a vibration detecting unit configured to detect a vibration of the vibration device, the control method comprising steps of:

• acquiring a detection signal indicating that the external apparatus is attached to the camera body;
• acquiring a vibration parameter corresponding to a type of the external apparatus to be attached to the camera body;
• and
• making the vibration device vibrate by using the vibration parameter,
• wherein when the detection signal is acquired, a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body is acquired from management data relating to a vibration parameter of the vibration device, and the vibration device is made to vibrate,
• wherein when the management data does not store the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body, a vibration parameter corresponding to the type of the external apparatus to be attached to the camera body is acquired by calibration that causes the vibration device to generate a vibration, and the vibration device is made to vibrate, and
• wherein in the calibration, the vibration device is caused to vibrate at a plurality of frequencies, and the vibration parameter corresponding to the type of the external apparatus to be attached to the camera body is acquired based on a detection result that the vibration detecting unit acquires when the vibration device is caused to vibrate at each of the plurality of frequencies.
