Abstract

FIELD: acoustics.
SUBSTANCE: invention relates to loudspeakers with self-aligning system. Device comprises a self-aligning system for suspension and alignment of outer edge of a diffuser. Self-aligning system consists of inner and outer bases. On outer base there are 3 or more external rollers to rotate about their axes. On inner base there are 3 or more inner rollers to rotate about their axes. Number of outer and inner rollers is equal. Inner and outer rollers are interconnected by closed rope or belt. Outer edge of diffuser is fixed on inner base of self-aligning system. Outer base self-aligning system is fixed on body of loudspeaker. Ratio between forces for displacement of centre of self-aligning system in crosswise and lengthwise directions is determined by ratio P2=P1*tgβ, where β is angle shift base relative to central position, which is considerably better than in existing suspensions.
EFFECT: high efficiency of alignment of diffuser.

Description

Изобретение относится к громкоговорителям или подобным электромеханическим преобразователям.The invention relates to loudspeakers or similar electromechanical converters.

Известны громкоговорители, у которых внешняя кромка диффузора центрируется с помощью подвесов, закрепляемых на внешней кромке диффузора и на корпусе громкоговорителя. (RU 2367114 C2)Loudspeakers are known in which the outer edge of the diffuser is centered by means of suspensions fixed on the outer edge of the diffuser and on the housing of the loudspeaker. (RU 2367114 C2)

Недостатком этого громкоговорителя является относительно высокое сопротивление перемещению диффузора, обусловленное жесткостью подвесов.The disadvantage of this speaker is the relatively high resistance to movement of the diffuser, due to the stiffness of the suspensions.

Целью изобретения является устранение этого недостатка.The aim of the invention is to eliminate this drawback.

Поставленная цель достигается тем, что внешняя кромка диффузора подвешивается с помощью самоцентрирующейся системы. Самоцентрирующаяся система содержит внутреннее и внешнее основание. На внешнем основании закреплены 3 или более внешних роликов с возможностью вращения относительно своих осей. На внутреннем основании закреплены 3 или более внутренних роликов с возможностью вращения относительно своих осей. Число внешних и внутренних роликов одинаково. Внутренние и внешние ролики соединены между собой замкнутым тросом или ремнем. При движении троса или ремня вдоль своего периметра все ролики поворачиваются с одинаковой линейной скоростью. Направление вращения внутренних и внешних роликов взаимно противоположны. Если внутренние ролики находятся в объеме V, то внешние ролики находятся за пределами этого объема. Одно из свойств самоцентрирующейся системы заключается в том, что при воздействии внешней силы P на внутреннее основание эта сила распределяется между внешними роликами натянутым ремнем или тросом. Возвращение в центр после прекращения действия внешних сил не зависит от силы натяжения ремня или троса. Центральное положение не изменяется при изменении температуры. This goal is achieved by the fact that the outer edge of the diffuser is suspended using a self-centering system. The self-centering system contains an internal and external base. On the external base 3 or more external rollers are fixed with the possibility of rotation relative to their axes. On the inner base 3 or more inner rollers are fixed with the possibility of rotation relative to their axes. The number of outer and inner rollers is the same. The inner and outer rollers are interconnected by a closed cable or belt. When a cable or belt moves along its perimeter, all the rollers rotate with the same linear speed. The direction of rotation of the inner and outer rollers are mutually opposite. If the inner rollers are in volume V, then the outer rollers are outside this volume. One of the properties of the self-centering system is that when an external force P acts on the internal base, this force is distributed between the external rollers by a tensioned belt or cable. Returning to the center after the termination of external forces does not depend on the tension force of the belt or cable. The central position does not change with temperature.

В известных подвесах сила Р1, необходимая для смещения центра подвеса в осевом направлении на величину h, приблизительно равна силе Р2, необходимой для смещения центра подвески в радиальном направлении на величину h. Разница лишь в том, что в первом случае сила направлена на разгибание дуги полуволны, если смотреть на поперечное сечение подвеса, а во втором случае на сгибание: Р1 ~ Р2. В самоцентрирующейся системе соотношение между этими силами определяется формулой: P1=Р2×tgβ, где β - угол отклонения центра системы относительно нормального положения, который не превышает угол 10 градусов. Отсюда следует, что при одной и той же силе Р2, необходимой для удерживания центра подвижной системы в центральном положении, сила Р1 в самоцентрирующейся системе намного меньше.In known suspensions, the force P1 required to displace the suspension center in the axial direction by h is approximately equal to the force P2 required to displace the suspension center in the radial direction by h. The only difference is that in the first case, the force is directed to the extension of the half-wave arc, if you look at the suspension cross-section, and in the second case, to the bending: P1 ~ P2. In a self-centering system, the ratio between these forces is determined by the formula: P1 = P2 × tgβ, where β is the angle of deviation of the center of the system relative to the normal position, which does not exceed an angle of 10 degrees. It follows that with the same force P2 necessary to hold the center of the moving system in a central position, the force P1 in the self-centering system is much less.

В примере конкретного исполнения на корпусе 6 громкоговорителя закреплена магнитная система 7, внешнее основание 1 самоцентрирующейся системы и центрирующая шайба 9 катушки 10. На внешнем основании 1 закреплены внешние ролики вращения 3, на внутреннем основании 2 закреплены внутренние ролики вращения 4. Внешние и внутренние ролики 3, 4 последовательно связаны между собой замкнутым ремнем 5, например резиновым. Внешняя кромка диффузора 8 закреплена на внутреннем основании 2.In an example of a specific embodiment, a magnetic system 7 is fixed to the loudspeaker body 6, the outer base 1 of the self-centering system and the centering washer 9 of the coil 10. On the outer base 1, the outer rotation rollers 3 are fixed, on the inner base 2 the inner rotation rollers are fixed 4. External and internal rollers 3 , 4 are sequentially interconnected by a closed belt 5, for example rubber. The outer edge of the diffuser 8 is fixed on the inner base 2.
