Abstract: A sound emitter device for use on a motor vehicle comprises a casing comprising an axial wall and a bottom wall, the axial wall extending along a vertical axis from the bottom wall toward an opening opposite the bottom wall, a control circuit, an acoustic membrane that closes the opening of the casing and that is provided on its lower face with excitation means controlled by the control circuit a peripheral rim that is arranged in the opening, the external peripheral edge of the acoustic membrane being mounted to bear on the peripheral rim, a secondary wall that is made in one piece with the peripheral rim and that is bent toward the peripheral rim so as to retain the acoustic membrane by clamping its external peripheral edge between the peripheral rim and the secondary wall.
