The present invention discloses a resonant loudspeaker for preventing dropping, comprising: a plastic bracket, wherein the bottom of the plastic bracket is provided with a clamping groove; a base, wherein the periphery of the base is clamped into the clamping groove; a voice coil arranged on an upper part of the base, wherein the top of the voice coil is connected with a coil; and a U cup, wherein the bottom of the U cup is connected with the coil, the upper part of the plastic bracket is bonded with an upper bouncing wave and one end of the upper bouncing wave is bonded with the U cup. The present invention adds the plastic bracket, a lower bouncing wave and the upper bouncing wave, so as to reduce distortion, realize smooth frequency response curve and effectively solve the problems of dropping, life and high distortion of a vibrating loudspeaker.

The present invention provides a multifunctional sounding device including a housing, a first vibration system, a second vibration system, a magnetic circuit system, an elastic component and a flexible circuit board. The elastic component includes a deformation part fixed to the second vibration system and an installation part extended from both ends of the deformation part and fixed to the housing. The second vibration system is suspended in the containment cavity through the elastic component. The flexible circuit board is connected with the elastic component, so that the vibration of the flexible circuit board is coupled with the vibration of the elastic component. Therefore, the damping of the elastic component is reduced, the force received by the elastic component during vibration is reduced, and the service life of the elastic component is extended.

A motor vehicle sound generator system has a housing in which a loudspeaker is accommodated. The housing has at least a first orifice and a second orifice. The orifices each have a sound transmission member provided thereon. The first orifice is arranged in a front side region of the loudspeaker and the second orifice is arranged in a rear side region of the loudspeaker as viewed in an axial direction of the loudspeaker. The sound generator system has a first sound outlet opening that is associated with the first orifice and a second sound outlet opening that is associated with the second orifice. The sound exits into open air through the first and second sound outlet openings, with the first and second sound outlet openings being free of exhaust gas flow.
