Definitions

  • the invention relates to a mobile communication terminal with a sound transducer for emitting sound signals.
  • Sound transducers provided in such mobile communication terminals usually have the sole purpose of reproducing voice or other audio signals received from or stored on the mobile communication terminals. This is usually done in a mono quality.
  • mobile communication terminals are particularly suitable because they are naturally always at hand and thus, for example, during the exercise of sports training, z. B. jogging, can be used to play music signals. Especially a music performance should adequately support and motivate the athlete during a workout.
  • the object of the invention is to expand a field of application for the sound transducer in a mobile communication terminal.
  • the sound transducer is designed to generate a virtual sound source
  • a detection device for a movement speed of the mobile communication terminal is provided and a processing device for output sound signals is provided, which the sound transducer due to the of Detection device provided movement speed such sound signals provides that the virtual sound source appears to be stationary.
  • a generation of a virtual sound source is to be assigned to the area of the prior art.
  • Suitable sound transducers for binaural sound reproduction are available to realize a virtual sound source, which is perceived by a person resting such that it is stationary in space.
  • the movement speed of the mobile communication terminal delivered by the detection device and thus the speed of movement of a person who carries the mobile communication terminal, enters a control for an arrangement of the virtual sound source in the room.
  • the processing device which can be implemented in software, is designed so that even with a movement of the mobile communication terminal in space, the virtual sound source appears stationary.
  • the sound transducer can mimic the sounds that may occur when the athlete passes by a virtual kilometer marker, such as applause or a gong sign.
  • the transducer emits audio signals that mimic sounds adjacent to the running track of standing virtual viewers.
  • the sound transducer may emit sounds of a fictitious person relating to indications of the performance of the athlete, such as his transit times, heart rate, etc.
  • the mobile communication terminal may be equipped with a heart rate measuring device. It is also possible that the acoustic impression of a specific environment (New York marathon route) is reproduced by the sound transducer over an entire running distance of the sportsman, whereby the associated audio data can be stored on the mobile communication terminal.
  • the detection device has an input interface for a variable, on the basis of which the movement speed can be calculated.
  • a variable on the basis of which the movement speed can be calculated.
  • the mobile communication terminal now has a pedometer, the speed of movement of the athlete can be calculated on the part of the mobile communication terminal. Due to the present movement speed, the processing device is able to predict an arrival direction of the sound of the virtual sound source over time, so that a fixed position of the virtual sound source is simulated.
  • the detection device can also detect the movement speed on the basis of measurements of a positioning device.
  • This locating device can for example, resort to position data provided by a GPS system with which the mobile communication terminal can be equipped.
  • the sound transducer is provided as connected to a housing of the mobile communication terminal headphones. In this way, the sound transducer is in a constant relative position to the athlete's head.
  • the mobile communication terminal M is equipped with a sound transducer K for generating a virtual sound source VS.
  • the sound transducer K is in the form of a headset, which is connected to an associated terminal on the housing of the mobile communication terminal M. Audio signals to be radiated by the sound transducer K are returned to output sound signals from a memory AD and are further processed by a processing device S.
  • the sound transducer K is acted upon by the processing device S, which is implemented in software, with sound signals for a binaural sound reproduction.
  • this processing is a value for a movement speed of the athlete or the mobile communication terminal M.
  • the mobile communication terminal M is equipped with a step sensor SS, which determines at which times the athlete has completed a step.
  • the mobile communication terminal M has an input interface SL, in which the athlete can enter his own stride itself. With the aid of the now available stride length and the times supplied by the step sensor SS for respective completions of a step, a detection device E can determine the movement speed of the athlete.
  • the value for the movement speed supplied by the detection device E is supplied to the processing device S, which supplies the sound transducer K with such sound signals that the virtual sound source VS generated by it remains substantially stationary for the calculated movement speed. This means that signals emitted by the sound transducer K are perceived by the athlete so that he passes the supposed location from which the sound signals originate during his run.
  • the mobile communication terminal M is additionally equipped with a GPS receiver G as a locating device whose delivered location information of the detection device E, which can be switched accordingly be provided. Due to the GPS location information and a detection each time between receiving two consecutive location information can be also determine the movement speed.
  • the detection device E is connected to a timer ZG.
  • the processing device S is able to calculate a respective angle of incidence for the sound signals coming from the virtual sound source VS with respect to the athlete, so that the virtual sound source appears to be stationary.
