Electronic device and method for outputting haptic feedback related to haptic actuator by using speaker

A method of an electronic device, the method comprising:

• outputting, through a speaker of the electronic device at a first volume, a first acoustic signal included in a media content;
• based on an occurrence of a preset event while outputting the first acoustic signal, identifying a posture of a housing of the electronic device by using a sensor of the electronic device;
• determining whether the posture of the housing of the electronic device corresponds to a reference posture associated with a direction in which the housing of the electronic device is vibrated by a haptic actuator;
• based on determining that the posture of the housing of the electronic device corresponds to the reference posture, outputting, through the speaker, a second acoustic signal representing a vibration notification regarding the preset event at a second volume different from the first volume;
• and
• based on determining that the posture of the housing of the electronic device does not correspond to the reference posture, outputting the vibration notification by controlling the haptic actuator of the electronic device while outputting the first acoustic signal based on the first volume.

A method of an electronic device, the method comprising:

• identifying an occurrence of a preset event;
• identifying, based on identification of the occurrence of the preset event, a direction of the electronic device by using a sensor of the electronic device;
• determine whether the direction of the electronic device corresponds to a reference direction associated with a direction in which a housing of the electronic device is vibrated by a haptic actuator;
• based on determining that the direction of the electronic device corresponds to the reference direction, outputting an acoustic signal representing a vibration notification regarding the preset event through a speaker in the electronic device;
• and
• based on determining that the direction of the electronic device does not correspond to the reference direction, refraining from outputting the acoustic signal through the speaker, and outputting the vibration notification regarding the preset event by vibrating the housing of the electronic device by using the haptic actuator.
