Abstract
Patente de Invenção: <B>"DISPOSITIVO/SISTEMAS DE IRRADIAçãO DE SOM"<D>. Irradiador de som tem uma série distribuída em área de transdutores acústicos múltiplos tendo recursos de acionamento individuais. Um grande número de transdutores pode ser usado e pode ser qualquer tipo. Os sinais de acionamento produzem irradiações de som diferentes na fase dos transdutores em distribuições sobre a área tendo natureza difusa desejada ou particularmente expressa. O recurso de produção de sinal de acionamento envolve mudança de fase do conteúdo de freq³ência acústica mais alta, e é adicionalmente operativo para ação em fase de pelo menos alguns dos transdutores em subárea(s) da série para conteúdo de freq³ência inferior.Invention Patent: <B> "SOUND IRRADIATION DEVICE / SYSTEMS" <D>. Sound radiator has a series distributed in the area of multiple acoustic transducers having individual actuation resources. A large number of transducers can be used and can be any type. The trigger signals produce different sound radiations in the transducer phase in distributions over the area having a desired or particularly expressed diffuse nature. The drive signal production feature involves changing the phase of the higher acoustic frequency content, and is additionally operative for in-phase action of at least some of the series subarea (s) transducers for lower frequency content.
