Abstract
The utility model discloses a flat plate radiation vibration loudspeaker which comprises a magnetic circuit drive system, a support system and a flat plate vibration system. The flat plate vibration system comprises a flat plate vibrating diaphragm, an elastic sheet and a coil. Through interaction between a permanent magnetic field generated in the magnetic circuit drive system and an electromagnetic field generated in the flat plate vibration system, force for making the coil in the flat plate vibration system move up and down is generated. As the coil is connected with the flat plate vibrating diaphragm, the coil drives the flat plate vibrating diaphragm to carry out piston motion, thus pushing the surrounding air to vibrate and producing sounds. According to the flat plate vibration system, a flat plate is used as a sounding body, the coil is used as a driving force, radiation sound waves are propagated in a nondirectional mode to make uniform coverage of a sound field, lowest resonant frequency of the flat plate radiation vibration loudspeaker is lower than that of a loudspeaker of the same kind, and low frequency sounds rich. Meanwhile, the flat plate radiation vibration loudspeaker has advantages of thin appearance, small volume, light weight and small occupying space.
