Radio Transmission Apparatus and Control Apparatus for Events Rooms as Well as Corresponding Method

Abstract

Radio systems for supplying hearing apparatus in events rooms are of a more convenient design. To this end a radio transmission apparatus is provided for transmission of speech signals in an events room. It possesses a receive device for receiving at least one control signal and a switching device for switching the radio transmission apparatus on and/or off depending on the received control signal. In addition a control apparatus is provided for controlling the radio transmission device, with which speech signals are transmitted in an events room. This control apparatus possesses a detection device to detect a presence or a movement of the radio transmission device in the events room and a transmit device for transmitting a control signal to the radio transmission device depending on the detection result of the detection device. This allows a transmit device of a teacher to be switched off when they leave the classroom.

1 . A radio transmission apparatus, comprising:
 a transmitting device that transmits a speech signal;   a receiving device that receives a control signal; and   a switching device that switches the transmitting device on and off depending on whether the receiving device receives the control signal.   
     
     
         2 . The radio transmission apparatus as claimed in  claim 1 , wherein the control signal is received via radio or inductively. 
     
     
         3 . The radio transmission apparatus as claimed in  claim 1 , further comprising a configuration device that automatically configures the radio transmission apparatus depending on the control signal. 
     
     
         4 . The radio transmission apparatus as claimed in  claim 3 , wherein the radio transmission apparatus is automatically switched into a radio channel based on the control signal. 
     
     
         5 . The radio transmission apparatus as claimed in  claim 1 , further comprising a mixing device so that a plurality of speech signals from a plurality of sound sources are mixed and transmitted. 
     
     
         6 . The radio transmission apparatus as claimed in  claim 1 , wherein the control signal comprises a sequence of signals. 
     
     
         7 . The radio transmission apparatus as claimed in  claim 1 , wherein the transmitting device is switched on if the receiving device receives the control signal or off if the receiving device does not receive the control signal. 
     
     
         8 . The radio transmission apparatus as claimed in  claim 1 ,
 wherein the transmitting device transmits the speech signal in an event room, and wherein the receiving device receives the control signal in the event room or at an entrance of the event room.
