Abstract
An electronic horn for use, e.g., in a vehicle, includes a piezoelectric element () that excites a plate-shaped oscillator (). A resonator () is provided with an opening () and covers forward of the oscillator such that a resonance space (S) is defined between the resonator and the oscillator. An inner cylinder () and an outer conical housing () are provided concentrically around the resonator. A circular cover () covers the inner cylinder () and the outer conical housing () from the front, such that a buffer chamber (BR), at least one first sound amplifying chamber (MH), and a second sound amplifying chamber (MH) are defined around an entire circumference of the opening of the resonator.
