Abstract
An acoustic output apparatus is provided. The acoustic output apparatus may include a vibration assembly and a mass element. The vibration assembly may include a piezoelectric structure and a vibration element. The piezoelectric structure may be configured to convert an electrical signal into mechanical vibrations, and the vibration element may be connected to the piezoelectric structure at a first position of the piezoelectric structure and configured to receive the mechanical vibrations to generate an acoustic signal. The mass element may be connected to the piezoelectric structure at a second position of the piezoelectric structure.
