Abstract:
1. A system for outputting an audible signal simulating a mechanical noise, the audible signal corresponding to an output force generated by a machine against a load, the system comprising: a machine configured to generate an output force against a load; a sense circuit including a pressure sensor configured to sense a pressure of a hydraulic fluid, the pressure being associated with the output force; a processor circuit coupled to the sense circuit, the processor circuit being configured to receive an input signal from the sense circuit in response to the sensed pressure and output audible signal data based on the input signal; an audio output circuit coupled to the processor circuit, the audio output circuit being configured to generate the audible signal in response to the audible signal data; and a vibration generator circuit coupled to the processor circuit, the vibration generator circuit being configured to generate vibrations in the machine in response to the audible signal data.
