An exemplary embodiment of the present disclosure may provide a sound generator which is connected to a vehicle body and generates sound, the sound generator including: a magnetic circuit generating vibration; a yoke contacting an upper surface of the magnetic circuit; an elastic member contacting at least a part of an upper surface of the yoke and performing vibration motion; a housing including an internal space formed as upper and lower sides of the housing are opened and lateral sides of the housing are closed; and a coil receiving an alternating current signal provided from the outside, wherein the coil is positioned in the internal space of the housing, wherein the sound generator transmits the vibration generated by the magnetic circuit to the vehicle body and vibrate at least a part of the vehicle body such that sound is generated from the vehicle body.

An ultrasonic transducer for wind turbine applications. The transducer includes a housing with a central diaphragm portion, a peripheral wall thereabout, and a flexure portion supporting the diaphragm portion relative to the peripheral wall. The apex of a cone is secured to the housing central diaphragm portion and the cone has a peripheral rim secured to the metal housing peripheral wall. A driver such as a piezoelectric element is secured to the housing central diaphragm portion opposite the cone apex.

A sound generator system of a vehicle is provided. The system includes a housing with an interior space formed therein and a cover that encloses the housing. An exciter is inserted into the interior space and includes yokes and a magnetic. A coil is positioned adjacent to the exciter and vibrates the exciter when current is applied. A main shaft has a first end connected to the housing a second end penetrating the cover, exposed to an outside, and penetrated and installed in the exciter and the vibration generated by the exciter if finally output. An elastic portion is installed adjacent to the exciter and delivers the vibration to the main shaft to remove removing a horizontal directional driving force of the exciter and prevent the exciter from contacting other components and enhances a vertical directional driving force of the exciter.
