FIELD: physics, optics.SUBSTANCE: invention relates to optical image capturing means. The image capturing device includes a speaker, a movable tube having a lens, an immovable tube in which an arched groove, which is engaged with a pin with a curved profile, provided on the movable tube and configured to move the movable tube, is formed on its internal periphery and external part, where the immovable tube is attached. An acoustic space is formed by the concavity of the external periphery of the immovable tube. The speaker is arranged to cover the acoustic space. An opening, which is connected to the acoustic space, is formed on the external part and the lower part of the acoustic space lies nearer to the optical axis of the lens than the lower part of the curved groove in the immovable tube.EFFECT: effective arrangement of the speaker independent of other functional units of the device.5 cl, 8 dwg |
