Definitions
- the invention relates to a communication device, in particular intercom or the like, for a vehicle with a microphone located inside the vehicle and a loudspeaker located outside the vehicle, an electronic circuit to which the microphone and the loudspeaker are connected, and a control device for the operation of the communication device.
- the invention is therefore based on the object of developing a communication device of the type mentioned in such a way that it offers greater comfort to the people communicating with one another and in particular increases the safety of the people in the vehicle.
- This object is achieved in that a second microphone is arranged outside the vehicle, that a second speaker is arranged inside the vehicle, and that the second microphone and the second speaker are connected to the electronic circuit.
- the second microphone and the second loudspeaker can now be used to hold calls from outside the vehicle into the vehicle interior without having to open the vehicle using the communication device according to the invention. This not only increases the comfort of the vehicle occupants, it also creates an amount for their safety.
- the communication device according to the invention can also be used to address passers-by safely at night and to ask about their wishes without having to open the vehicle.
- the communication can also take place in a slowly rolling vehicle without the need to stop the vehicle.
- the vehicle occupants of two vehicles, each of which is equipped with a communication device according to the invention can connect to one another, and this is the case with moving vehicles.
- the first microphone and / or the first loudspeaker are advantageously located in the area of the driver's seat, in particular in the area of the driver's head. This measure not only enables interference-free reception by means of the microphone and largely eliminates background noises.
- the speaker located in the immediate vicinity of the head of the vehicle driver can now be set to a relatively low sound level, which has the advantage that the vehicle driver can still understand the signals emitted by the speaker very well, but other people inside the vehicle cannot be disturbed.
- the second microphone and / or the second loudspeaker are arranged in the front area of the vehicle.
- the person outside the vehicle stops in the front area of the vehicle, since eye contact with the driver can be established there. If the microphone and the loudspeaker are now also in this area, problem-free communication between the people inside the vehicle and the person outside the vehicle is possible.
- the electrical circuit sets the second, outer microphone to "ON" and the first, inner microphone to "OFF” in a first operating position. If the communication device is switched on, the electrical circuit assumes the first operating position and the vehicle occupants can hear outside. In this way it is ensured that information can easily get into the car from the outside, but the vehicle occupants are protected from the fact that their conversations are being transmitted to the outside. An inadvertent transmission of a conversation from the vehicle interior to the outside is therefore excluded.
- the first operating position is preferably indicated by a first signal lamp.
- a lighting up of the signal lamp signals to the vehicle occupants that the communication device is switched on and that the microphone located outside the vehicle is activated. Switching off the communication device cannot be forgotten in this way with a high degree of probability.
- the electrical circuit can be switched into a second operating position by actuating the switching device, in which the first microphone is set to "ON” and the second microphone is set to "OFF".
- the switching device expediently consists of a button that resets itself, so that unintentional activation of the microphone located in the vehicle interior is excluded.
- the second operating position can also be indicated by a second signal lamp.
- This signal lamp shows e.g. other people in the vehicle interior that calls are being transmitted from the vehicle interior to the outside. It therefore offers security against unwanted transmission of confidential information.
- a mechanical button or an electronic sound balance is preferably provided for actuating the switching device for switching the electronic circuit from the first operating position to the second operating position.
- the mechanical push button offers the advantage that the second operating position is only assumed by consciously pressing the push button and conversations can thus reach the outside of the vehicle.
- the electronic sound scale has the advantage that, depending on the sound level, the microphone that has the higher switching level is switched on. No mechanical actuation is required in this embodiment, so that e.g. both hands can remain on the steering wheel.
- the sensitivity limit of the sound scale is adjustable so that it e.g. Only from a certain level of a sound level does the electronic circuit switch from the first to the second operating position.
- the volume of the loudspeakers is adjustable and can be changed, in particular, from inside the vehicle.
- the volume of the loudspeaker provided in the vehicle interior can be changed so that it is directed at a single person, for example the Vehicle driver or to everyone in the vehicle interior is coordinated.
- the volume of the outer loudspeaker can be set as desired depending on the outside noise.
- a recording device can be connected to the communication device according to the invention.
- Figure 1 is a perspective representation of a
- Figure 2 is a schematic schematic diagram of the communication device according to the invention.
- a vehicle 1 shows a vehicle 1, which is only shown as an example and is provided with the communication device according to the invention.
- a unit 7 which has a microphone 5 and a loudspeaker 6 and which can be handled as an independent element.
- a second unit 9 which has a second microphone 10 and a second loudspeaker 11.
- a further unit 13 can also be provided in the area of a front fender 12, which also contains a second microphone 14 and a second loudspeaker 15.
- a person inside the vehicle 2 can connect to outside people.
- the outside people can communicate via the microphones 10 and 12 with the person in the vehicle interior 2, with information coming from outside through the loudspeaker 6 and conversations coming from the vehicle interior 2 through the loudspeakers 11 and 15 to the outside be transmitted.
- the units 9 and 13 are housed in a weatherproof housing 23, so that they e.g. is sufficiently resistant to weather influences such as splash water, dew, frost, etc., road dirt, salt, lubricants and fuels.
- FIG. 2 illustrates the structure of the overall number 16
- a switching device designated overall by 18, is also connected to the electrical circuit 17. Furthermore, rotary switches 24 and 25 can be seen, with which the volume of the loudspeakers 6 and 11 and 15 can be adjusted.
- the mode of operation of the communication device 16 is described below.
- a signal lamp 20 lights up and signals to the vehicle occupant (s) that the communication device 16 is switched on.
- actuation of the switch 19 creates a connection between the microphone 10 or 14 of the external unit 9 or 13 and the loudspeaker 6, which is located in the interior 2 of the vehicle.
- the vehicle occupants can now receive noises from outside. If a button 21 is operated, so the connection of the microphone 10 or 14 to the loudspeaker 6 is interrupted and a connection is established between the microphone 5 and the loudspeaker 11 or 15.
- this circuit state is indicated to the vehicle occupants by a signal lamp 22. In this second operating position, noises are transmitted from the vehicle interior 2 to the outside.
- the electrical circuit 17 immediately returns to the first operating position and interrupts the connection of the microphone 5 to the loudspeaker 11 or 15. At the same time, the signal lamp 22 goes out.
- a sound balance can also be used be provided, which weighs the sound level of the microphones 5 and 10 or 14 against each other and switches on the microphone, which has the higher sound level.
- the communication device 16 With such a communication device 16, people in the vehicle interior 2 can communicate with people standing outside without the vehicle interior 2 having to be opened. In addition to increased comfort, the communication device 16 according to the invention also offers significantly higher safety for the vehicle occupants, since they can remain in the vehicle interior 2 and are protected by the vehicle 1.
