  Luftakustischer Apparat zur Aufnahme oder Übertragung der Schallenergie aus der
Luft oder auf dieselbe. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
Die Erfindung ist nicht auf die in den Figuren dargestellte   Ausführungsform     beschränkt,   vielmehr sind diese nur als Ausführungsbeispiele zu betrachten. So kann z. B. bei der Ausbildung der Figuren der 
 EMI2.1 
 vorgesehen sein zur Herabsetzung oder Vergrösserung der Strahlungsdämpfung. 



   PATENT-ANSPRÜCHE :
1. Luftakustischer Apparat zur Aufnahme oder Übertragung der Schallenergie aus der Luft oder auf dieselbe nach dem Patente Nr. 96235, gekennzeichnet durch eine konische Gestaltung des als Strahlungsorgan wirkenden Resonatorraumes, um ungewollte Mediumbewegungen in demselben   mög-   
 EMI2.2

  Air-acoustic apparatus for the absorption or transmission of sound energy from the
Air or on the same.
 EMI1.1
 

 <Desc / Clms Page number 2>

 
The invention is not limited to the embodiment shown in the figures, rather these are to be regarded only as exemplary embodiments. So z. B. in the formation of the figures
 EMI2.1
 be provided to reduce or increase the radiation attenuation.



   PATENT CLAIMS:
1. Air-acoustic apparatus for receiving or transmitting the sound energy from the air or onto the same according to patent no.
 EMI2.2

Claims (1)

2. Luftakustiseher Apparat nach Anspruch 1, gekennzeichnet durch eine solche Konusform des als Strahlungsorgan wirkenden Resonatorraumes, dass der Zulaufquerschnitt zu der Kommunikations- öffnung für das Medium, der durch den Mantel eines Zylinders von der Höhe des Raumes über der Kommu- nikationsöffnung und mit dem Umfang dieser Öffnung gebildet wird, mindestens ebenso gross ist, wie der Querschnitt der Kommunikationsöffnung selbst. 2. Air acoustics apparatus according to claim 1, characterized by such a conical shape of the resonator chamber acting as a radiation organ that the inlet cross-section to the communication opening for the medium, which passes through the jacket of a cylinder from the height of the room above the communication opening and with the Perimeter of this opening is formed, is at least as large as the cross section of the communication opening itself. 3. Luftakustischer Apparat nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass der'Reso- natorraum durch mehrere Kommunikationsöffnungen mit dem Aussenmedium in Verbindung steht, zu dem Zwecke, die Gesamtweglänge für das schwingende Medium zu verringern. 3. Air-acoustic apparatus according to claims 1 and 2, characterized in that der'Resonatorraum is connected to the outside medium through several communication openings, for the purpose of reducing the total path length for the vibrating medium. 4. Luftakustischer Apparat nach den Ansprüchen 1 bis 3, dadurch gekennzeichnet, dass die elastische Kraft des Resonators diejenige der Schallplatte derart überwiegt, dass das aus Resonator und Schallplatte gebildete System nur eine ausgesprochen Eigenschwingung besitzt. EMI2.3 4. Air-acoustic apparatus according to claims 1 to 3, characterized in that the elastic force of the resonator outweighs that of the record in such a way that the system formed from the resonator and record has only one pronounced natural oscillation.
