Definitions

  • the invention relates to an assembly for hands-free function of a phone in a vehicle according to the preamble of patent claim 1, furnished with sound reproducers, as a radio, for instance.
  • Hands-free functions in vehicles are previously known to be so arranged that in the vehicle the phone is in a phone rack and by means of separate cables a separate loudspeaker has been brought close to the driver's head.
  • the assembly also comprises a hands-free unit, which is to be connected, among other things, to the power source, at least in order to carry out sound amplification imperative for the loudspeaker.
  • the communication line between phone rack and connecting unit can be easily done wireless, while the microphone is kept, for instance, in the phone rack.
  • the connecting unit is arranged close to the radio, most suitably behind it, which makes the installation easy.
  • Fig. 1 shows schematically one assembly as per the invention.
  • Fig. 2 shows a phone rack.
  • the figure 1 assembly is an example of a device system implementing the hands-free function of a vehicle.
  • the vehicle has a radio 1 including loudpeakers 12.
  • a phone rack 3a In the lower part of the rack there are outlets and inlets known per se for the phone cables.
  • connecting unit 2 In the assembly there is from phone rack 3a outlet a cable 4 to connecting unit 2, which is, for instance, a box placed behind the radio.
  • Microphone 11 can be held in the phone rack, for instance, or it can be somewehere along cable 4 in a proper place branched out from the cable. The voice travels along cable 4 to connecting unit 2.
  • the connecting unit 2 When a call is received or sent by the telephone in the phone rack, the connecting unit 2 detects the message arriving along cable 4 and switches off the connection along cables 7 from radio 1 to loudspeakers 12. Instead, the connecting unit connects the sound signal arriving along cable 4 to cables 10 going to loudspeakers 12.
  • the connecting unit contains sound amplification in order to make the voice come out loud enough from the loudspeakers.
  • the voice is controlled by means of connecting unit 2 to sound from radio loudspeakers 12 in connecting the sound signals amplified by the unit to cables 10 leading to the loudspeakers and disconnecting the cable connetion 7 from radio las long as the the call lasts.
  • connecting unit 2 there are inlets to connecting unit 2 for current feed 8 and cables 7 and outlets for cables 10.
  • Cable 4 can also be replaced by a wireles connection.
  • the switched on radio becomes mute automatically.
  • control takes place over the phone to the connecting unit, then by means of control the connecting unit selects the adjusted degree of amplification for the volume from the loudspeakers.
  • the connecting unit transforms the voice into an antenna signal, whereby the call moves along antenna cable 6 to radio 1.
  • the connecting unit contains an apparatus to transform the voice into an antenna signal.
  • the call passes in a way known per se all channels meant for this purpose by means of the control coming from the connecting unit and the voice is directed to the loudspeakers over cable 7 and further to cables 10.
  • the voice quality and volume can be adjusted by the radio controls and components contained in the radio.
  • the current feed (cable 5) can be conducted to radio 1 through the connecting unit.
  • the common antenna 9 of phone and radio can be conducted to connecting unit 2 or cable 9 is the antenna cable of the phone only or the antenna cable of the radio only. Also individual antennas are possible either for radio or phone or both.
  • Connecting unit 2 is most suitably a box mountable direct behind the radio resulting in short cables.
  • Another embodiment of the invention contains the voice trans- formation facility, Digital Signalling Processing (DSP), as transformation of voice, for instance as far as the wave bands and frequency responses of all bands are concerned and, naturally, voice adjustment as to its volume.
  • DSP Digital Signalling Processing
  • the phone rack 3b includes an optional apparatus with processing program and controls for voice transformation. In both cases, whether transformation is made from phone or rack control 13, the connection to loudspeakers 12 can be made direct through radio 1 by means of cables 7. If the voice is recycled through the radio, it can then also be RF based transformation.
  • Connecting unit 2 performes muting of radio on arrival of a call.
