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.

First claim

What is claimed is:

1. 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.

2. The elevator system of claim 1 , wherein the first elevator car component is one of an elevator car wall panel, an elevator car frame element, an elevator car support element, an elevator ceiling panel, an elevator floor panel, an elevator car operating panel, or an elevator car door.

3. The elevator system of claim 1 , wherein the at least one audio actuator coupled to the second side of the first elevator car component comprises a plurality of audio actuators.

4. The elevator system of claim 1 , wherein the first elevator car component is composed of plastic, metal, glass, or wood.

5. The elevator system of claim 1 , wherein the audio system controller controls the at least one audio actuator to generate sound within the interior of the elevator car in response to a triggering event.

6. The elevator system of claim 5 , wherein the triggering event is at least one of an opening of elevator car doors, destination input by a passenger at a car operating panel, arrival at a destination floor, or an emergency announcement.

7. The elevator system of claim 1 , further comprising an elevator controller wherein the audio system controller is in communication with the elevator controller to receive information therefrom.

8. The elevator system of claim 1 , further comprising a spectral analysis device located within the interior of the elevator car and configured to enable tuning of the structural sound-generation system.

9. The elevator system of claim 1 , wherein the structural sound-generation system comprises a plurality of audio actuators arranged around the elevator car.

10. The elevator system of claim 9 , wherein the audio system controller controls the plurality of audio actuators to generate sounds at specific locations within the interior of the elevator car by controlling vibration from the plurality of audio actuators to a plurality of different elevator car components.
