Definitions

the invention relates to a computer-controlled electro-acoustic discussion system according to the preamble of claim 1.
Electroacoustic discussion systems facilitate or enable the mutual acoustic communication of the participants in a discussion, conference or the like.
the participants have the microphones at their disposal which can be switched on and off by means of the computer in the central office.
the spoken word is made audible via loudspeakers or headphones, which are connected to the central amplifier unit.
the speakers can be housed in the microphones, for example.
the participants in the discussion can express their requests to speak by pressing the button on their microphone.
the microphone in question is switched on immediately or later in the course of processing an electronically stored message list. As a rule, only one microphone is switched on at a time. However, depending on the program, a small number of microphones can also be switched on together.
by pressing a Ta stature at the head office the specific activation of certain microphones possible.
the electrical connection between the microphones and the control center runs over a single common cable which forwards both the sound or microphone signals and the generally digitally coded signaling and control signals from and to the microphones.
the cable works as a bus, i.e. it does not establish an individual connection between the individual microphones and the control center.
Each microphone has control electronics that are individually coded to distinguish the microphones from each other so that the individual microphones can be addressed individually from the control center by means of an address contained in the control signal.
the signaling signals emanating from the control electronics contain the individual address, which enables the relevant microphone to be recognized by the computer of the control center.
the cable connecting the microphones to the control center is freely laid in the room in which the discussion system is to be operated.
the control electronics and the preamplifier of each microphone are housed in a common housing, to which the incoming and the further section of the cable is connected and to which the microphone, which consists of a microphone capsule and housing, is also permanently or pluggably connected via a feed line.
the housing for preamplifier and control electronics is e.g. designed as a microphone console, to which the microphone is connected via a gooseneck and to which the pushbutton switch is also attached.
the invention has for its object to design a discussion system of the generic type so that the permanent equipment of a conference room with a discussion system is possible with comparatively little investment.
only permanently installed microphone sockets are provided at the individual microphone locations, which are connected to the control center via the only cable that is also permanently installed in the room.
Preamplifiers, control electronics and pushbuttons for each microphone are no longer permanently arranged at each microphone location, but are integrated in the microphone, which can be connected to one of the microphone sockets via its connector.
Fixed installation of the cable and the microphone sockets are easy to manufacture and not expensive, even if a microphone socket is provided at every or every second subscriber location. Only the microphones with integrated preamplifier and integrated control electronics are more expensive. However, the operator of the conference hall only has to purchase these in a comparatively small number, corresponding to the average, incomplete occupancy of the conference hall.
the microphones required in addition to the basic equipment can simply be rented for the duration of the event and easily connected to the existing microphone sockets.
the capital expenditure for the permanent furnishing of the conference hall remains low and additional expenditure arises only and only as long as the conference hall is actually fully used.
a particularly advantageous embodiment of a microphone of the new discussion system with an integrated preamplifier and integrated control electronics can be found in claim 3.
the discussion system shown in the figures comprises a center 1, to which a plurality of microphones 2 are electrically connected via a single, common cable 3.
the cable 3 is eight-wire. It is permanently installed in the room in which the discussion system is operated and the furniture indicated here by several armchairs 5.
a microphone socket 4 is permanently attached to the furniture or armchair 5 for two armchairs.
the cable 3 connects all the microphone sockets 4 to one another by looping through from the microphone socket to the microphone socket.
the microphones 2 each have a connecting cable 27 with a connector 28 matching the microphone sockets 4, so that they can be connected directly to the common cable 3 via each of the microphone sockets 4.
the control center 1 comprises an amplifier device 11 for amplifying the sound or microphone signals coming from the microphones 2.
the amplifier device 11 controls loudspeakers in a manner not shown in detail or headphones via a transmission device.
the control center 1 further comprises a computer 12 operating according to the program, which receives digitally coded message signals from the microphones 2 via two wires of the cable 3 and transmits digitally coded control signals to the microphones 2 via two wires of the cable 3.
the control center 1 further comprises a power supply 13 which, in addition to the amplifier device 11 and the computer 12 via the cable 3, also feeds the electrical assemblies contained in the individual microphones 2 and to be explained in more detail.
Each microphone contains in a housing 21, cf. FIGS. 2-4, a customary microphone capsule 22, a preamplifier 23 for the microphone signals and control electronics 25 indicated by the switch symbol.
a pushbutton switch 24 which can be actuated by the discussion participants is provided on the housing.
the microphone signals from the preamplifier 23 pass through two speech wires of the common cable 3 to the amplifier device 11 in the control center 1 when the control electronics 25 have switched on the microphone 2 in question due to corresponding control signals from the computer 12 in the control center 1.
the respective operating state of the microphone is indicated by an LED 26, cf. Figure 4, which lights up when the microphone is switched on.
the control electronics 25 of each microphone are individually coded according to a one-time manual setting for a specific address.
the control electronics receives all control signals from the computer 12, but responds to a control signal only if it has the address corresponding to the respective coding contains.
the control electronics 25 also generates signal signals in accordance with the actuation of the pushbutton switch 24, which likewise carry an address corresponding to the respective coding of the control electronics 25.
the message signals go via the cable 3 to the computer 12 and are processed there depending on the respective program of the computer, for example in such a way that the computer 12 immediately switches on the microphone 2 by means of suitable control signals, in which the key switch 4 was actuated, and all other microphones turns off, or in such a way that the computer 12 sets the microphone 2, in which a key switch 4 has been actuated, to a stored message list and only switches on when the computer in the course of processing the message list at the microphone in question has arrived.
FIG. 2 to 4 show further structural details of one of the same microphones 2.
the housing 21 of the microphone 2 has the shape of a rectangular cylinder with rounded longitudinal edges.
the microphone capsule 22 is arranged on one end 31 of the housing, which is on the left in FIG.
the LED 26 is provided in the end wall or the speaking screen 31.
the flexible connecting cable 27, which ends at the plug 28, emerges from the opposite end 32.
the key switch 24 is installed in the large side wall 33 of the housing 21 shown in FIG. 2.
the LED 26 could also be provided in this upper side wall 33, for example in structural association with the pushbutton switch.
a circuit board 29 extends between the two ends 31 and 32, which both in conventional technology contains the preamplifier 3 and the control electronics 25.
Preamplifier and control electronics are thus integrated into the microphone 2; Via the connecting cable 7 and the plug 28 which can be inserted into one of the microphone sockets 4, a direct galvanic connection to the cable 3 is thus made without the insertion of further electrical modules.
the housing 21 can e.g. be designed as a double-shell plastic housing.
a number of microphones 2 corresponding to the number of discussion participants present, where the discussion participants are sitting, is connected by means of the plug 28 to the permanently installed microphone sockets 4.
the remaining microphone sockets 4 in the room remain unoccupied.
the operator of the conference room only has a comparatively small number of microphones 2. He rents additional microphones 2 for large events.
two discussion participants share a microphone. Both of them can comfortably take the microphone 2 due to its design as a hand microphone with a longer, flexible connecting cable 27 and use it without having to bend over to the microphone or even have to go to the microphone.
