Изобретение относитс  к области электромехашгческих преобразователей, а именно к акустическим агрегатам.The invention relates to the field of electromechanical transducers, namely, acoustic units.

Известен акустический агрегат, содержащий звуковую колонку, в которой укреплены электроакустические преобразователи 1.Known acoustic unit containing a sound column, in which the electroacoustic transducers 1 are fixed.

Недостатком этого акустического агрегата  вл етс  мала  направленность создаваемого им акустического излучеВИЯ .The disadvantage of this acoustic unit is the small directivity of the acoustic radiation generated by it.

Известен также акустический агрегат, содержащий звуковую колонку/ в которой укреплены электроакустические преобразователи , держатель и корпус Г21.Also known acoustic unit containing a sound column / in which the electroacoustic transducers, the holder and the case G21 are fixed.

Этот акустический агрегат позвол ет обеспечить требуемую направленность акустического излучени . Однако его об- спу снванне затруднительно.This acoustic unit provides the desired directivity of acoustic radiation. However, his help is difficult.

Цель иэсйретёни  - упрощение обслужн вани  акустического агрегата.The goal of the design is to simplify the maintenance of the acoustic unit.

Поставленна  цель достигаетс  тем, что в предлагаемый акустический агрегат введены сопр женные одно с другим с возможностью самоторможени  черв чнов колесо и черв к, установленные в держателе, выполненном в виде П-образной обоймы, имеющей установочные риски-и смонтированной с возможностью поворота в корпусе вокруг оси, перпенаикул рно к оси вращени  черв чного колеса . При этом звукова  колонка жестко укреплена на черв чном колесе, расположенном ПР9ТИВ установочных рисок держател , а черв к снабжен поворотной ручкой.The goal is achieved by the fact that the proposed acoustic unit is connected with one another with the possibility of self-retarding the worm wheel and worm wheel mounted in a holder made in the form of a U-shaped cage, having installation risks and mounted with the possibility of rotation in the housing around axis perpendicular to the axis of rotation of the worm wheel. In this case, the sound column is rigidly fixed on the worm wheel, which is located on the holder’s mounting scratches, and the screw is equipped with a rotary knob.

На чертеже схематически предлагаемый акустический агрегат.In the drawing is a schematic of the proposed acoustic unit.

Предлагаемый акустический агрегат содержит звукойую колонку 1, в которой укреплены электроакустические преобразоэатепи . Звукова  колонка с помощь соединительного элемента 2 жестко укреплена на черв чном колесе 3. Черв чное колесо установлено с возможностью врашени  с помощью вала 4 в держателе 5, выполненном в виде П-образной обоймы. В держателе расположен также черв к 6, снабженный поворотной ручкой 7. Черв чное коThe proposed acoustic unit contains a sound column 1, in which electroacoustic transforms are reinforced. The sound column with the help of the connecting element 2 is rigidly fixed on the worm wheel 3. The worm wheel is installed with the possibility of adhesion by means of the shaft 4 in the holder 5, made in the form of a U-shaped cage. In the holder there is also a worm to 6, equipped with a rotary knob 7. A worm gear
