Description

The invention relates to a sound engineering system comprising a mixer, at least one audio source and at least one audio cable according to the preamble of claim 1.

The invention also relates to a mixer with at least one audio interface according to the preamble of claim 17.

The invention also relates to an audio cable.

A generic audio engineering system is for example in the DE 20 2005 000 536 U1 described.

In audio engineering it is known to record various instruments, singers and the like with separate microphones for the purpose of conducting an event or a music production. The thus obtained audio signals, which may be, for example, vocals, synthetic sounds, sounds of individual instruments or whole ensembles, are then usually transmitted via cable to a so-called mixing console. Depending on the orchestra or ensemble size, sometimes up to forty or more individual transmissions and thus audio interfaces at the mixing console are required.

Nowadays almost exclusively (three-pole) XLR connectors are used for the cabling. These connectors are designed for the toughest stage use and not least for this reason, relatively large. The XLR connectors also include a locking device in the coupler that prevents the connector from being accidentally disconnected.

Other backgrounds to known sound systems can also the generic DE 20 2005 00 536 U1 which describes a multi-channel mixing console that can be used for merging and mixing multiple audio sources, for example, XLR connectors can be used for the cable connection between the mixer and audio source.

However, the known audio engineering systems have disadvantages.

In particular, the cost of wiring is sometimes very high. Care must be taken to connect the correct audio sources to the correct audio interfaces of the mixer. Faults in the wiring can be remedied only time consuming and must be avoided if possible to ensure a correct mix. Experience has shown that the cabling is primarily concerned with the correct assignment of the many audio cables, but that it is not particularly careful, also due to the time pressure, that plug-in connections were used when plugging in and unplugging the audio cables. The additional locking device of the XLR connectors makes their handling even more difficult. It is known that a large part of the defective audio cables or microphone cables were mechanically damaged by improper unplugging. This is true even for the robust and large-sized XLR connectors.

Large connectors (eg, XLR connectors) also have the further disadvantage that the interface area of the mixing consoles, where the many audio sources must be merged, are very large. This complicates the transport, storage and handling of the known mixing consoles.

The present invention has for its object to provide an improved audio engineering system that allows a simple and possible damage-free plugging and unplugging of audio cables to a mixer.

The present invention is also based on the object of providing a mixing console whose audio interfaces are simple and convenient.

Finally, it is an object of the invention to provide an audio cable for use in a sound engineering system which overcomes the known disadvantages of the prior art.

The object is achieved for the audio engineering system by claim 1, for the mixer by claim 17 and for the audio cable by claim 18.

The dependent claims relate to advantageous embodiments and variants of the invention.

The audio engineering system according to the invention comprises a mixer with at least one audio interface with electrical contacts, at least one audio source and at least one audio cable for electrically connecting the at least one audio source to the at least one audio interface of the mixer. The at least one audio cable has a first connector with electrical mating contacts, which forms a first connector with the at least one audio interface.

According to the invention it is provided that the first connector a magnetic closure and is formed such that the electrical contacts of the audio interface with the electrical mating contacts of the first connector contact the front side.

Basically, the invention is suitable for use in the entire audio engineering, for example in stage technology, event technology and music production, for. B. in a recording studio. The invention is particularly suitable for use with a public address system.

The device referred to as a mixer can also be referred to as an audio mixer or sound mixer and serves essentially to mix electrical audio signals from different audio sources. The mixing together can serve for example for recording and / or direct sound. Mixers and their use are basically already known, which is why the further details are not discussed.

The at least one audio interface may in particular be a device connector, for example a socket, of the mixing console.

Connectors or device connectors are used to produce an electrical and mechanical connection with a correspondingly compatible or complementary additional connector. A connector may be a plug, a socket, a coupling or an adapter. The term "connector" used in the context of the invention is representative of all variants. The combination of a connector with a corresponding compatible or complementary connector (for example, the audio interface) is referred to herein as a connector.

The cable referred to as audio cable may be an electrical cable for the exclusive transmission of electrical audio or audio signals. However, the audio cable can also serve to transmit, in addition to the electrical audio signals, further electrical signals, for example analog and / or digital control or data signals, identification signals and / or electrical supply signals. The invention is basically not limited to the use of a particular (audio) cable type.

Under a front-side electrical contacting electrical contacts of the audio interface with electrical mating contacts of the first connector is to be understood that touch the electrical contacts and the electrical mating contacts at the front side contacting, in contrast to an insertion into each other, for example in the manner of a pin / sockets Contact or wire spring contact. However, it can also be provided within the scope of the invention that the first connector and the audio interface are plugged into each other, for example by appropriate design of the respective housing. It comes within the meaning of the invention, only on the fact that their electrical contacts and mating contacts are frontally contacted.

A magnetic closure may be provided, for example, by the connectors (for example the first connector and the audio interface) participating in the connector each having at least one magnetic body.

A magnetic body may be magnets, magnetizable parts or magnetic parts which react magnetically under the influence of a magnet. To form a magnetic closure, at least one of the magnetic bodies of the magnetic closure is designed as a magnet, for example as a permanent magnet or as an electromagnet.

It can be provided that one of the connectors involved in the connector (eg the first connector or the audio interface) has one, two or more permanent magnets and the other connector (eg the audio interface or the first connector) one, two or more soft magnets, eg. B. iron parts having. It can also be provided that both connectors involved in the connector each have one, two or more permanent magnets, which are mutually oppositely aligned with a closed connector. A combination of permanent magnets and soft magnets in a connector is possible.

Instead of or in addition to a permanent magnet and an electromagnet can be used.

It is envisaged that the respective magnetic bodies of the connectors involved (eg the first connector and the audio interface) cooperate in such a way that a magnetic force results on both connectors through a magnetic field. In this way, a magnetic holding force can be generated, which holds the connector in the closed state. Only when a defined tensile or shear force is exceeded, the magnetic closure can be opened and thus the connectors involved are separated.

The necessary forces for opening the connector can be selected and thus the magnetic closure be designed such that it is ensured that the magnetic closure releases before mechanical damage to the audio cable and / or a connector can occur. This can be done by the selection, design, alignment, number and / or positioning of the magnetic body.

The audio engineering system according to the invention can have a compact and robust construction and is easy to operate. Characterized in that an end-side electrical contact is provided in contrast to a plug, the necessary for connection to the audio sources (or speakers) connectors can be easily operated. For the subsequently necessary holding force of the connector can provide the magnetic closure.

Characterized in that a magnetic closure is provided, the connector can be particularly easily closed by the magnetic guiding forces of the magnetic body, for example, without eye contact with the connectors.

Finally, it is also ensured by the magnetic closure that the connector remains securely closed, with costly or inconvenient mechanical locking systems and their operation omitted.

The degradation of the audio engineering system according to the invention is comparatively simple. By the frontal contacting of the electrical contacts and mating contacts and by the magnetic closure of the connector, the connector can be opened by the at least one audio cable is only removed from the mixer. Mechanical damage is almost impossible.

In one development of the invention, it can be provided that the at least one audio source has an audio source interface and the at least one audio cable has a second plug connector, which together form a second plug connection.

An audio source interface may in particular be a device connector, for example a socket of the audio source.

The fact that the audio cable forms a second plug-in connection with the audio source, the sound system can be made even more flexible. The advantages and features that have been mentioned with respect to the first connector are equally applicable to the second connector.

Characterized in that the audio cable has a first connector at one of the two ends and a second connector at its other end, the respectively desired length of the audio cable can be adapted to the situation by selecting a suitable audio cable. The audio cable is thus not firmly or inseparably connected to the audio source on one side. A damaged audio cable can thus easily be replaced by another one.

Alternatively, however, it can also be provided that the at least one audio cable is connected at one end directly to the audio source. A second connector can therefore be omitted. It can also be provided that a part of the audio sources directly, d. H. without a second plug connection, and a part of the audio sources are connected to the mixer via a second plug connection.

One or more of the audio sources may also have a conventional connector, such as an XLR connector. The at least one audio cable may then have, for example, at one end an XLR connector for connection to the audio source and at the other end a first connector for connection to the audio interface of the mixer.

In one embodiment of the invention can be provided that the second connector has a magnetic closure and is preferably identical in design as the first connector.

The second plug-in connection can preferably be formed in electrical and / or mechanical respect and / or with respect to the magnetic closure identical to the first plug connection.

The fact that in the presence of a second connector this can be formed identical to the first connector, the audio engineering system according to the invention is further simplified, since care must be taken in a cabling to the orientation of the audio cable. Thus, each of the ends of the audio cable can be selectively connected to the audio source interface or the audio interface.

In a development, it can be provided that at least one of the audio interfaces of the mixing console is designed as an audio input and / or at least one of the audio interfaces of the mixing console is designed as an audio output.

Thus, the sound system or the mixing console of the audio engineering system can be used to merge one or more audio sources into one or more audio output signals and provide at least one audio output.

In a further development, it can finally be provided that at least one loudspeaker and / or a recording device is provided and connected to at least one of the audio interfaces via one of the audio cables.

For the purposes of the invention, a loudspeaker means any sound generator capable of converting electrical audio signals into acoustic audio signals or sound.

Thus, an audio signal can be output from the mixing console via the at least one loudspeaker connected to one of the audio interfaces, preferably an audio output, and / or recorded by the recording device.

According to the invention, therefore, one or more speakers and / or one or more recording devices can advantageously be connected to the mixer. This can be done in an analogous way, as already described with respect to the audio sources. The features and advantages mentioned above and below apply accordingly. In principle, the skilled person is only able to replace the term "audio source" with the term "loudspeaker" or "recording device" for this purpose.

It can be provided in particular that the at least one speaker has a speaker interface (in particular a device connector of the speaker) and the at least one audio cable has a second connector, which together form the second connector, wherein the second connector is preferably identical, as the first connector , This also applies analogously to the at least one receiving device.

For the connection of a loudspeaker, a recording device and / or the connection of an audio source advantageously the same audio cables can be used.

In one development of the invention it can be provided that the at least one audio source is designed as a synthesizer and / or as a sound receiver, preferably microphone, pickup and / or hydrophone.

In principle, the invention is not intended to be limited to use with a particular audio source, speaker, or recording device. It may, for example, also be provided that audio signals of one or more audio sources are first preprocessed via one or more amplifiers and / or filters and / or via a so-called "stage box", over which the audio engineering system may optionally have. Furthermore, one or more outputs of the amplifier and / or filter and / or the stage box can then be connected to the mixer via one or more additional audio cables, the amplifier, the filter and / or the stage box then being referred to as audio source in the sense of the invention can be.

In one embodiment of the invention can be provided that the first connector and / or the second connector is one to ten-pole, preferably three to seven-pole and very particularly preferably three-pole, is or are.

Accordingly, the audio cable can be one to ten-pole, preferably three to seven-pole and very particularly preferably three-pole.

The number of poles used of the at least one audio cable of the first connector and / or the second connector need not be identical; An adaptation at the connection point can also be provided.

For improved signal transmission, a shielding of the audio cable and / or the plug connections can be provided.

In one embodiment of the invention may also be provided that the first connector and / or the second connector (and / or the at least one audio cable) is set up for symmetrical signal transmission or are.

For example, a symmetrical, three-pole signal transmission in the manner of an XLR connection may be provided.

It can also be provided an asymmetric signal transmission.

In one development of the invention it can be provided that the audio interface, the audio source interface, the first connector and / or the second connector has a diameter which is smaller than 20 mm, preferably smaller than 15 mm and particularly preferably smaller than 10 mm.

The audio interface, the audio source interface, the first connector and / or the However, second connectors can also be made larger than 20 mm, for example greater than 25 mm or greater than 30 mm.

Preferably, however, the audio interface, the audio source interface, the first connector and / or the second connector is smaller than a conventional XLR connector. Due to the fact that mechanical damage to the plug connections according to the invention can be largely ruled out, in particular by using the magnetic closure, the corresponding plug connections can be made smaller than is possible in the known state of the art. As a result, for example, the mixer, which usually has a variety of audio interfaces, turn out smaller. The handling, transport and storage of the mixer or the sound system can be improved.

In a further development of the invention may finally be provided that the electrical contacts or mating contacts of the audio interface, the audio source interface, the first connector and / or the second connector are formed as flat contacts and / or pin contacts and preferably spring mounted.

For example, so-called pogo pins or spring contact pins can be provided. Alternatively or additionally, the flat contacts may be spring-mounted.

For example, the electrical contacts of the audio interface and / or the audio source interface as flat contacts and the electrical mating contacts of the first connector and / or the second connector may be formed as pin contacts, in particular as pogo pins - or vice versa. It can be provided as a mixed contacts training electrical contacts and / or mating contacts of the connectors as flat contacts and pin contacts, even within a single connector.

The magnetic force of the magnetic closure is preferably dimensioned such that it is greater than the force with which the resiliently mounted electrical contacts / electrical mating contacts repel each other, so that a secure connection is ensured despite the opposing spring forces.

In principle, any type of contact for forming the electrical contacts and the electrical mating contacts may be provided, which allow an end-side contacting.

In a further development it can be provided that the audio interface, the audio source interface, the first connector and / or the second connector are each formed identically.

It can be provided in particular that all connectors for the transmission of audio signals within the audio engineering system are constructed identically. It can thus be provided a hermaphroditic structure of the sound system. In handling, especially in a structure of the system thus highest flexibility and compatibility of the components of the audio engineering system is given. Furthermore, it is not necessary to pay attention to orientation or the correct selection of audio cables.

In a development of the invention it can be provided that the magnetic closure has a mechanical coarse guidance and a magnetic fine guidance.

A mechanical rough guide can be realized for example by a correspondingly pronounced housing at least one of the connectors involved such that the second connector is mechanically coarsely demonstrated during insertion.

In order to avoid jamming and to ensure easy insertion, a corresponding mechanical clearance in the mechanical rough guide and / or a cone-like running rough guide can be provided.

An exact positioning and centering of the parts to be joined may result from the magnetic effects of the magnetic closure. The magnetic closure thus realizes a magnetic fine guidance, so that the connector to be connected to the audio interface or the audio source interface only has to be "rough" and an exact alignment of the connector such that the electrical contacts and mating contacts close in the intended orientation , which results in magnetic fine guidance.

For this purpose, it may already be sufficient to bring the connector in the vicinity of the mechanical coarse guide or to introduce the connector into the mechanical coarse guide; the correct alignment is then taken over by the magnetic fine guidance of the magnetic closure.

For example, in a first step (mechanical rough guide), a mechanical connection between the connectors involved in the connector can be created, which can be performed without much effort and which can be produced clearly and safely. After production of the mechanical connection or even during the production of the mechanical connection can then be an automatic, possibly even no longer influenceable production of the electrical contact with accurate orientation of the contacts and mating contacts to each other by the magnetic forces (magnetic fine guide).

In a development, it may also be provided that the magnetic closure has a magnetic coding in order to close the first and / or second plug connection only in a defined orientation.

The magnetic closure may also include magnetic coding to associate certain audio cables and / or audio sources with defined audio interfaces, thereby preventing erroneous mapping and closing or being magnetically closed only when the proper audio cables and / or audio sources are plugged in associated audio interfaces are connected.

In particular, when using a variety of audio sources, it is important to know which instrument, which singer or orator, etc. is fed on which channel or on which audio interface of the mixer. Only then is it possible for the sound engineer to operate the correct slider or "fader" and properly tune the respective instrument, the singer, the speaker or the other audio source in the volume and the sound. Ensuring the right wiring is known to be very time consuming and error-prone. Magnetic coding can solve this problem.

Alternatively and / or in addition to a magnetic coding, a mechanical coding can also be provided.

It can also be provided that certain groups of audio interfaces, for example audio inputs, audio outputs or other groups, are provided for a specific magnetic coding in order to be connectable only to a corresponding associated audio source or a correspondingly assigned loudspeaker or audio cable.

In a development of the invention it can be provided that the magnetic closure comprises an electromagnet.

It can also be provided that the magnetic closure comprises an electro-permanent magnet.

When using an electromagnet and / or Elektropermanentmagneten as part of the magnetic closure, the magnetic closure may be electrically controlled, for example from the side of the mixer or other user interface of the audio engineering system.

In a development, it can be provided that by controlling the at least one electromagnet, an audio cable assigned to the audio interface can be magnetically locked and / or unlocked.

In the simplest case, one or more switches or buttons may be provided to open at least one of the magnetic locks and thus at least one of the (first) connectors. It is also possible to provide program code means of a computer program product, in particular of the mixing console, in order to lock or unlock at least one of the magnetic locks by activating the at least one electromagnet in response to a user request.

Thus, if, for example, the sound system is to be dismantled, all connections of the sound system or at least the mixer can be solved by pressing a button or possibly by other input devices, for example by a mouse click.

The magnetic holding force between the connectors involved can be interrupted, after which the one or more audio cables fall from the audio or the audio interfaces. But it can also be provided that the one or more audio cables are repelled by the audio or the audio interfaces by the at least one electromagnet is reversed and interacts with a counter magnet in the first or second connector accordingly.

Preferably, the mixing console is arranged to control the at least one electromagnet such that a connected audio cable is locked and / or unlocked.

In one development of the invention, the audio engineering system may include a tablet computer, a notebook and / or a mobile terminal, which are so communicatively connected to the mixer and set up to be used as a user interface for the mixing of audio signals.

In particular, if the connectors according to the invention have small diameters, and the mixer can be built very small. The entire audio engineering system can then be made compact. Nevertheless, a comfortable To enable operation or blending, the blending itself can take place on a tablet computer, a notebook, a mobile terminal or a corresponding screen on which virtual sliders are preferably displayed touch-sensitive. The blending can also be much more flexible than on a conventional mixer and can be almost any changed, updated and modified.

The communication link between the tablet computer, notebook and / or mobile terminal and the mixer may be wired or based on a wireless standard, such as a Bluetooth standard, a WLAN standard, a ZigBee standard or other wireless standard, especially within the ISM band ,

An identification device may be provided as part of the audio engineering system to make identifiable an audio source connected to the mixer via an audio cable and / or a loudspeaker connected to the mixer via an audio cable and / or a mixing device connected to the mixer.

The identification device may be part of the audio source, the loudspeaker and / or the recording device.

It can also be provided that the identification device can be connected as an adapter between the audio source or the loudspeaker or the recording device and the audio cable.

The identification device can transmit an electronic identification or identification via the audio cable to the mixing console. The mixer can finally be set up to recognize the connected audio source or the connected speakers or the connected recording device based on the identification and automatically "route" the corresponding audio signal to the correct slider or fader.

The identification device can be designed to be programmable in order to be adaptable to different audio sources or loudspeakers or recording devices.

The identification device can be designed as a microprocessor. Instead of or in addition to a microprocessor, any further device for implementing the identification device can be provided, for example one or more arrangements of discrete electrical components on a printed circuit board, an application-specific integrated circuit (ASIC) or another programmable circuit.

The identification signal can be transmitted via a specially provided in the audio cable data line and / or modulated as an additional signal to the actual audio signal to be transmitted and filtered out in the mixer.

By using the identification device, the wiring of the audio engineering system is substantially simplified and error sources are reduced.

The invention also relates to a mixer with at least one audio interface with electrical contacts for connection to electrical mating contacts of a first connector of an audio cable, wherein the at least one audio interface with the first connector forms a first connector. It is provided that the at least one audio interface with the first connector forms a magnetic closure and the electrical contacts of the audio interface are formed to contact the electrical mating contacts frontally.
