Abstract

Акустические устройства имеют элементы, проходящие поперечно толщине и способные переносить поперечные волны, вызывающие в результате акустическое действие посредством зонального распределения резонансных режимов собственных колебаний поперечной волны, совместимых с желаемым достижимым акустическим действием упомянутого элемента в желаемом рабочем диапазоне звуковой частоты. Пространственное распределение жесткости, включающее изменение (изменения) ячеек, используется, чтобы получить желаемое местоположение для преобразователя поперечной волны и/или хорошее акустическое действие резонансного режима при обычно невыгодной форме элементов. Возможны элементы с комбинацией привода поршневого действия и возбуждения поперечной волны в центре массы и геометрическом центре.Международная заявка была опубликована вместе с отчетом о международном поиске.Acoustic devices have elements passing transversely to thickness and capable of transmitting transverse waves, resulting in an acoustic effect through the zonal distribution of resonant modes of the transverse wave, compatible with the desired achievable acoustic action of the said element in the desired working range of sound frequency. The spatial distribution of stiffness, including changes (changes) of cells, is used to obtain the desired location for the transverse wave transducer and / or a good acoustic effect of the resonant mode with usually unprofitable form of elements. Elements are possible with a combination of a piston drive and shear wave excitation at the center of mass and the geometric center. The international application was published along with an international search report.
