  "Perfectionnements aux instruments de musique à   vent",   Il est fait usage, pour la bonification et l'anplification du son émis par les instruments de musique,de boites spéciales, appelées résonateurs,décrites au brevet principal   no356.3I4,   du ler décembre 1928. 



   La présente invention a pour but d'étendre l'emploi de ces auxiliaires à tous les appareils destinés à émettre des sons , 
A titre d'exemple,et pour mieux faire ressortir la portée de l'idée,la figure 1 ci-jointe représente un résonateur à   appli-   quer à un appareil téléphonique et à y attacher au moyen d'une simple vis, Ce processus rend la parole plus   claire,plus     distinc-   te et plus sonore, Cette figure représente la coupe   longitudi-   

 <Desc/Clms Page number 2> 

 nale du dispositif   dans/lequel   A est le transmetteur téléphoni- que et   B   le résonnateur. 



   La figure 2 donne un autre type de grandeur pouvant   être   applique au porte-voix de marina; par exemple,cette dernière application peut,suivant lesproportions du   résonateur,servir   avantageusement pour annoncer à longue distance, soit dans les    cafés, brasseries ,restaurants ,meetings, réunions sportives, criées,    salles de vente,etc. 



   La présente invention peut s'étendre à une foule d'autres domaines,telles que téléphonie sans fil,tranpas d'automobiles, syrènes de bateaux,microphones,instrumants à   corda, etc. Elle   peut servir également de base dans la construction des scènes de théâtres,salles de concert, etc. 



   En tous cas, les avantages de'la présente invention parais- sent tout de suite dans l'obtention,en toute   circonstance,d'un   son bonifié et clarifié plus pur, plus sonore et plus distinct.

  "Improvements to musical wind instruments", It is used, for the improvement and amplification of the sound emitted by musical instruments, special boxes, called resonators, described in main patent no 356.3I4, of December 1, 1928 .



   The object of the present invention is to extend the use of these auxiliaries to all devices intended to emit sounds,
As an example, and to better emphasize the scope of the idea, the attached figure 1 shows a resonator to be applied to a telephone apparatus and to be attached to it by means of a simple screw. the speech clearer, more distinct and more sonorous, This figure represents the longitudi-

 end of the device in which A is the telephone transmitter and B the resonator.



   Figure 2 gives another type of magnitude that can be applied to the marina megaphone; for example, the latter application can, depending on the proportions of the resonator, be used advantageously for long-distance announcements, either in cafes, brasseries, restaurants, meetings, sporting meetings, auctions, sales rooms, etc.



   The present invention can be extended to a host of other fields, such as cordless telephony, automobile transport, boat sirens, microphones, string instruments, etc. It can also be used as a basis in the construction of stages of theaters, concert halls, etc.



   In any case, the advantages of the present invention are immediately apparent in obtaining, in all circumstances, an enhanced and clarified sound that is purer, more sonorous and more distinct.
