Description

Electronic device comprising a vibration motor The embodiments disclosed in this document relate to an electronic device including a vibration motor. To improve the usability and portability of electronic devices, electronic devices with new form factors that allow the device's appearance to be varied depending on the situation are being developed. For example, there are foldable devices equipped with flexible displays that can be folded or unfolded, or slideable devices that can expand or contract the screen. As another example, devices equipped with optionally pop-up cameras are being developed that allow most of the front surface area of the device to be utilized as a screen display area. As described above, the variable electronic device may include a first housing and a second housing capable of rotational or linear motion relative to the first housing. To move such housings, the electronic device may include a motor and a drive unit. The motor may convert electrical energy into kinetic energy. The drive unit may be composed of gears, such as a rack and pinion, or a lead screw, for example, to transmit kinetic energy from the motor to the housings to move them.
