Description
Изобретение относитс к измерительной технике , а именно к конструкции акустических головок.The invention relates to a measurement technique, namely to the design of acoustic heads.
Известны акустические головки, содержащие ньезоэлемент и соединенный с ним первым торном звукопровод, выполненный из волокои, закрепленных на торцах звукопровода в чейках сетки.Acoustic heads are known that contain a heavy element and a sound guide connected to it by the first torn, made of fibers, fixed on the ends of the sound guide in the cells of the grid.
Однако -в известных акустических головках имеетс неравномерность пол излучени .However, in the known acoustic heads there is an uneven radiation field.
С целью устранени этого недостатка в предлагаемой головке концы на втором торце закреплень в чейках сетки относительно чеек нервой сетки по таблице случайных чисел.In order to eliminate this drawback, in the proposed head, the ends at the second end are fixed in the grid cells relative to the nerve grid cells according to the table of random numbers.
На чертеже изображена предлагаема акустическа головка.The drawing shows the proposed acoustic head.
Акустическа голов.ка содержит пьезоэлемент /, соединенный с ним нервым торцом звукопровод 2, выполненный из волокон 3, закренленных на торцах звукопровода в чейках сетки 4. Волокна, св занные с участком пьезоэлемента , излучение которого искажает основное поле излучени , например волокна, соединенные с участком поднайки .контакта 5, другими своими концами-закреплены на втором торце звуконровода в чейках сетки 4 ио таблице случайных чисел. Акустическое ноле направл етс в изделие 6 через второй торец зву2The acoustic head contains a piezoelectric element /, a suction line 2 connected to it with a nerve end, made of fibers 3, engraved at the ends of the suction line in the cells of the grid 4. with a plot of a sublevel .contact 5, with its other ends-fixed on the second end of the sound conductor in the cells of the grid 4 and on the table of random numbers. Acoustic zero is guided into article 6 through the second end of the sound.
копровода 2, образующий рабочую поверхность головки.coprod 2, forming the working surface of the head.
Работает акустическа головка следующим образом.The acoustic head works as follows.
Пьезоэлемент / возбуждает в каждом волокне 3 один и тот же тин колебаний. Последние , распростран сь по волокнам, доход т до рабочей поверхностн головки и излучаютс в изделие 6, где в результате интерференц«и иолей отдельных волокон формируетс поле излучени голоики. Однородна область ньезоэлемецта 1 в силу одинаковой длины волокои создает в изделии основное регул рное поле.The piezoelectric element / excites in each fiber 3 the same vibration type. The latter, spreading through the fibers, reach the working surface of the head and are emitted into the product 6, where as a result of the interference and the elements of the individual fibers, the radiation field of the holoika is formed. The homogeneous area of the electrical element 1, by virtue of the same length, the filament creates in the product the main regular field.
Излучение участков, внос щих искажени в основное поле излучени пьезоэле.мента /, распределено по всей рабочей поверхности головки в соответствии с таблицей случайных чпсел , в результате чего обеспечиваетс равиомерность пол излучени акустической головки .The radiation of portions that distort the main radiation field of the piezoelectric element / is distributed over the entire working surface of the head in accordance with the table of random crowns, as a result of which the radiation field of the acoustic head is equalized.

Акустическа головка, содержаща иьезоэлемент и соединенный с ним первым торцом звукопровод, выполненный из волокон, закрепленных на торцах звуконровода в чейках сетки, отличающа с тем, что, с целью новышенй равномерности пол излучени головки , .концы волокон на втором торце закреплены в чейках сетки -относительно чеек первой сетки по таблице случайных чисел.An acoustic head containing an acoustic element and a sound conductor connected to it by the first end, made of fibers fixed at the ends of the sound conductor in the grid cells, is characterized in that relative to the cells of the first grid in the table of random numbers.
