Abstract

Patente de Invenção:<B>"DISPOSITIVO ACúSTICO CONFIANDO SOBRE A AçãO DE ONDA FLETORA"<D>. Dispositivo acústico compreendendo um membro confiando sobre a ação de onde fletora com distribuição vantajosa de seus modos ressonantes, no qual o membro tem sua área acusticamente ativa pelo menos parcialmente delimitada por dispositivos tendo uma natureza substancialmente coibitiva em relação à vibração de onda fletora. A operação pode ser abaixo da coincidência, ou acima se desejado para o dispositivo acústico ativo tendo locação vantajosa de dispositivos transdutores de onde fletora determinada com referência a e levando em conta a ação dos dispositivos delimitadores.Invention Patent: <B> "ACOUSTIC DEVICE TRUSTING ABOUT FLECTOR WAVE ACTION" <D>. Acoustic device comprising a member relying on the action from which it bends with advantageous distribution of its resonant modes, in which the member has its acoustically active area at least partially delimited by devices having a substantially restraining nature in relation to the bending wave vibration. The operation can be below coincidence, or above if desired for the active acoustic device, having advantageous location of transducer devices from which the bending is determined with reference to and taking into account the action of the delimiting devices.
