Devices, systems, and methods for inducing automotive body vibration

A device comprising:

• a power supply;
• a processor circuit comprising a processor and a memory;
• a user interface operating on the processor circuit and configured to receive a user selection of a frequency and amplitude;
• at least one amplifier in communication with the user interface and configured to:
• receive power from the power supply;
• and
• output an alternating current electrical signal at the selected frequency and amplitude;
• and
• at least one linear transducer separate from the vehicle and configured to:
• attach to a vehicle;
• receive the alternating current electrical signal at the selected frequency and amplitude;
• and
• generate a vibration at the selected frequency and amplitude,
• wherein when the at least one linear transducer is attached to the vehicle, the vibration generated by the at least one linear transducer is transmitted into components of the vehicle.

A method comprising:

• providing a processor circuit comprising a processor and a memory;
• providing at least one amplifier in communication with the processor circuit;
• receiving a selection of a frequency and amplitude via a user interface operating on the processor;
• receiving power from a power supply into the at least one amplifier;
• and
• outputting an electrical signal at the selected frequency and amplitude from the at least one amplifier;
• attaching at least one linear transducer to a corresponding at least one location on a vehicle;
• receiving the electrical signal at the selected frequency and amplitude into the at least one transducer;
• and
• generating a vibration at the selected frequency and amplitude from the at least one linear transducer,
• such that the vibration is transmitted into components of the vehicle to reproduce a vibration generated by the vehicle moving over a rumble road or shaking on a shaker table.
