Definitions

  • the invention relates to an electronic and digital circuit to make it possible to produce extra engine sound to an existing engine.
  • the engine speed is measured.
  • One or more other engine sounds are stored into digital memory. Based on the speed of the engine an extra engine sound will be produced by controls of a CPU and a Digital Sound Processor (DSP).
  • DSP Digital Sound Processor
  • the object is to produce an extra or special engine sound. This is normally done on a mechanical way, like an exhaust systems or extra parts on an engine.
  • This invention provides the possibilities to add extra sound to an engine or make an engine sound like a complete other engine.
  • a normal car or any other device with an engine
  • This object is achieved by storing one or more engine sounds on digital memory.
  • the digital produced engine sound will follow the speed of the original engine.
  • the functionality can be realised by a CPU controlled electronic circuit. See figure 2 , the functional diagram example on page 4. Detailed materials and component selection can be varying, since many different electronic and digital parts are available in the market. Therefor a basic explanation is provided how the functionality can be realised.
  • the original engine can be in many vehicles like cars, motorbikes, and trucks. If a 'car' is mentioned in this document, all kind of these vehicles is actually referred to.
  • the vehicle where this device can be used is not limited to a specific type or model.
  • the speed of the original engine is measured. This can be done by using the pulses for the engine speed indicator (Tacho or RPM) like most modern cars have. Separate speed pick-up devices can also be used to achieve this.
  • the device can be turned on and off. If more engine sounds are stored into memory, the user can select the desired sound that must be produced Volume of the produced sound can be adjusted
  • the memory is mainly used to store one or more different engine sounds. Memory can also be used for remembering settings and variables of the device.
  • the CPU controls all data. Based on the speed of the engine and the selected sound by the user, the audio sound processor (DSP) will receive audio sounds from the memory.
  • DSP audio sound processor
  • the DSP converts the digital sounds into an analogue audio signal.
  • the audio amplifier converts the analogue sound of the DSP to the desired signal level for a speaker.
