Oscillator for a flat loudspeaker, flat loudspeaker and vehicle

A flat loudspeaker, in particular for or in the field of aviation and aerospace, comprising:

• a sound transducer for generating and transmitting acoustic waves,
• a vibration exciter for a flat loudspeaker comprising:
• a vibration member carrier,
• a coil carrier which carries a coil, and
• a coupling ring which serves to couple the vibration exciter to a sound transducer of a loudspeaker,
• wherein the vibration member carrier and the coupling ring are connected to each other by a releasable quick-fit closure device which has first closure elements for a secure connection locked in relation to vibrations and which provides second closure elements, which are separate therefrom, for a firm connection between the vibration member carrier and the coupling ring,
• wherein the vibration member carrier is connected with the coil carrier and has a resilient system that is inwardly directed relative to the coil carrier;
• wherein the vibration exciter is connected to the sound transducer and is configured to excite the sound transducer for transmitting acoustic flexural waves.

A flat loudspeaker, in particular for or in the field of aviation and aerospace, comprising:

• a sound transducer for generating and transmitting acoustic waves, and
• a vibration exciter for a flat loudspeaker comprising:
• a coil carrier which carries a coil;
• a vibration member carrier which is connected to the coil carrier and which has an inwardly directed resilient system which is inverted relative to the coil carrier in such a manner that the resilient system is arranged completely inside the structure of the coil carrier;
• and
• a coupling ring which serves to couple the vibration exciter to a sound transducer of the flat loudspeaker and which is releasably connected to the coupling ring by a closure device,
• wherein the vibration exciter is connected to the sound transducer and is configured to excite the sound transducer for transmitting acoustic flexural waves.

A vehicle, in particular aircraft or spacecraft, comprising:

• at least one passenger compartment for vehicle passengers,
• at least one flat loudspeaker having a sound transducer for generating and transmitting acoustic waves, and a vibration exciter for a flat loudspeaker, comprising:
• a vibration member carrier,
• a coil carrier which carries a coil, and
• a coupling ring which serves to couple the vibration exciter to a sound transducer of a loudspeaker,
• wherein the vibration member carrier and the coupling ring are connected to each other by a releasable quick-fit closure device which has first closure elements for a secure connection in relation to vibrations and which provides second closure elements, which are separate therefrom, for a firm connection between the vibration member carrier and the coupling ring, and
• wherein the vibration member carrier is connected with the coil carrier and has a resilient system that is inwardly directed relative to the coil carrier;
• wherein the vibration exciter is connected to the sound transducer and is configured to excite the sound transducer for transmitting acoustic flexural waves, for acoustic irradiation of the passenger compartment, the panel of the flat loudspeaker itself forming a portion of the passenger compartment.
