Cylindrical acoustic wavefront generation by means of ionic speakers
We present the use of ionic transducers to generate acoustic waveforms of cylindrical shape. We resorted to “cold discharge” transducers where momentum transfer from ions to neutral molecules is the main sound-generating process. Since the electrodes can be given a fairly arbitrary shape and the air...

I28-R145-53_oai2026-02-11 Gomez, Pablo D'onofrio, Enrque Santiago, Guillermo Daniel 2018-12-03 We present the use of ionic transducers to generate acoustic waveforms of cylindrical shape. We resorted to “cold discharge” transducers where momentum transfer from ions to neutral molecules is the main sound-generating process. Since the electrodes can be given a fairly arbitrary shape and the airflow is normal to the former, it is possible to obtain, close to the electrodes, a wavefront quite different from those obtained with standard, piston-like, loudspeakers. We present the acoustical characteristics of a cylindrical transducer and the use in the study of a bandpass, sonic-crystal based filter. Presentamos la generación de frentes de onda acústicos cilı́ndricos usando transductores iónicos. Estos transductores están basados en la transferencia de momentum lineal por colisiones entre iones generados en una descarga corona y moléculas neutras. Dado que la forma de los electrodos puede ser elegida con gran flexibilidad, es posible obtener un flujo de aire que, en las vecindades del emisor, tiene asociado un frente de onda que se aparta de los conseguidos habitualmente con pistones planos. Mostramos las caracterı́sticas acústicas de un transductor cilı́ndrico y, como aplicación, el uso en el estudio de un filtro pasabanda basado en un cristal sónico. application/pdf application/msword text/html https://elektron.fi.uba.ar/elektron/article/view/53 10.37537/rev.elektron.2.2.53.2018 spa eng FIUBA https://elektron.fi.uba.ar/elektron/article/view/53/42 https://elektron.fi.uba.ar/elektron/article/view/53/418 https://elektron.fi.uba.ar/elektron/article/view/53/135 Derechos de autor 2018 Guillermo Daniel Santiago, Pablo Gomez, Enrque D'onofrio Elektron Journal; Vol. 2 No. 2 (2018); 47-52 Revista Elektron; Vol. 2 Núm. 2 (2018); 47-52 Revista Elektron; v. 2 n. 2 (2018); 47-52 2525-0159 2525-0159 ionic transducers acoustic radiation sonic crystals transductores iónicos radiación acústica cristales sónicos Cylindrical acoustic wavefront generation by means of ionic speakers Generación de frentes de onda acústicos cilíndricos a través de parlantes iónicos info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=53_oai |

We present the use of ionic transducers to generate acoustic waveforms of cylindrical shape. We resorted to “cold discharge” transducers where momentum transfer from ions to neutral molecules is the main sound-generating process. Since the electrodes can be given a fairly arbitrary shape and the airflow is normal to the former, it is possible to obtain, close to the electrodes, a wavefront quite different from those obtained with standard, piston-like, loudspeakers. We present the acoustical characteristics of a cylindrical transducer and the use in the study of a bandpass, sonic-crystal based filter. |
