Abstract

Способ и устройство для определения благоприятного места (мест) для размещения преобразователя изгибных волн в функциональной связи с элементом (элементами), работающим в звуковом режиме, на основе резонансных мод из-за действия изгибных волн в таком элементе (элементах). Способ включает в себя возбуждение с целью анализа действия акустически релевантных изгибных волн в указанном элементе и систематическую оценку измеримого эффекта (эффектов), связанного с таким действием изгибных волн и соответствующего указанному звуковому действию, при этом эффекты изменяются в соответствии с местоположением преобразователя изгибных волн в пределах области указанного рассматриваемого элемента. Возбуждение с целью анализа осуществляют путем приложения акустической энергии к указанному рассматриваемому элементу с тем, чтобы создать указанное акустически релевантное действие изгибных волн с помощью преобразователя, выборочно функционально связываемого в пределах области указанного элемента для получения отклика на действие изгибных волн в нем, при этом в качестве измеримого эффекта (эффектов) используют сигналы от указанного преобразователя или посредством преобразователя изгибных волн, выборочно функционально связываемого в пределах области указанного рассматриваемого элемента с тем, чтобы создать указанное акустически релевантное действие изгибных волн.Международная заявка была опубликована вместе с отчетом о международном поиске.A method and apparatus for determining a favorable place (s) for placing a flexural wave transducer in functional connection with an element (s) operating in sound mode, based on resonant modes due to the action of bending waves in such an element (s). The method includes excitation to analyze the action of acoustically relevant bending waves in the specified element and systematically assessing the measurable effect (s) associated with such an action of bending waves and corresponding to the specified sound action, while the effects vary according to the location of the bending wave transducer within the area of the specified considered element. The excitation for the purpose of analysis is carried out by applying acoustic energy to the specified considered element in order to create the specified acoustically relevant effect of bending waves using a transducer selectively functionally connected within the region of the specified element to obtain a response to the action of bending waves in it, measurable effect (s) use signals from the specified transducer or by means of a flexural wave transducer, selectively functionally connected within the region of the specified element in question in order to create the specified acoustically relevant action of the bending waves. The international application was published together with the international search report.
