发明名称 VIBRATOR AND ELECTRONIC APPARATUS HAVING THEREOF
摘要 Disclosed are a vibration generator, which can increase the vibration force of a vibration plate by additionally applying the mass of a mass body to the vibration plate, and an electronic device including the same. The vibration generator includes at least one piezoelectric element mounted inside the case and subjected to compression and expansion in response to input power, a vibration plate including a body elongated in a preset lengthwise direction and having the at least one piezoelectric element mounted thereon, and generating vibrations by the compression and expansion of the at least one piezoelectric element, and at least one mass part adding a preset magnitude of mass to the vibration plate.
