Abstract
Elevator systems including an elevator car moveable within an elevator shaft, the elevator car having a first elevator car component, the first elevator car component having a first side facing an interior of the elevator car and a second side opposite from the first side and a structural sound-generation system. 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.

An elevator system comprising:
- an elevator car moveable within an elevator shaft, the elevator car having a first elevator car component, the first elevator car component having a first side facing an interior of the elevator car and a second side opposite from the first side;
- and
- a structural sound-generation system comprising:
- 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, wherein 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;
- a second elevator car component having a respective first side facing the interior of the elevator car and a respective second side opposite from the first side of the second elevator car component;
- and
- the structural sound-generation system includes at least one second audio actuator coupled to the second elevator car component and arranged to generate vibrations within the second elevator car component such that sound waves are produced therefrom and projected into the interior of the elevator car,
- wherein the first elevator car component and the second elevator car component are made of different materials selected to generate different sounds.
