The structural sound-generation system having at least one audio actuator coupled to the second side of the first elevator car component and an audio system controller in communication with the at least one audio actuator. The structural sound-generation system is configured to generate vibrations within the first elevator car component such that sound waves are produced therefrom and projected into the interior of the elevator car.
