Abstract

A vibration speaker with facial plate has developed for delivering sound in a form of vibrational movement to a user's skin. The vibration speaker includes a voice coil to generate a magnetic force in response to application of a sound signal from an exterior, a magnet having a predetermined magnetic force to interact with the magnetic force from the voice coil, a basket to receive the magnet, a face plate to deliver upward and downward movement of the voice coil or the magnet to the user's skin, and a rear cover coupled to the face plate to constitute an appearance of the vibration speaker. The face plate is provided with a plate-shaped tensioner providing a predetermined tension for maintaining the face plate in a horizontal state to control upward and downward vibrational movement delivered from the vibration speaker.
