Abstract

The invention discloses a loudspeaker device, comprising an external frame and a loudspeaker component. A rotating slot with an upward entrance and a clamping slot of which entrance faces the rotating slot are arranged in the external frame. A rotating disk is rotationally mounted in the rotating slot through a rotating bearing. A middle end slot is arranged at a middle end of the rotating disk. A rise and fall arm is mounted in the middle end slot based on a sliding mode. An internal spiral hole with downward entrance is arranged in the rise and fall slot. A rise and fall spiral rod is mounted in the internal spiral hole through thread matching. A rotating middle end shaft is rotationally mounted at a lower end of the middle end slot through the rotating bearing. The upper end of the rotating middle end shaft is fixedly connected with the rise and fall spiral rod. The lower end of the rotating middle end shaft stretches to the clamping slot and is fixedly mounted with an upper rotating tooth-shaped wheel. An internal tooth edge is fixedly mounted at a bottom end of the clamping slot. A vertical side sliding cavity stretching along a vertical side is arranged in the rotating disk. A sliding frame is mounted in the vertical side sliding cavity based on the sliding mode. A rise and fall motor is fixedly mounted in the sliding frame.

Description

technical field [0001] The invention relates to the field of loudspeaker equipment, in particular to a loudspeaker device. Background technique [0002] A loudspeaker is a device that can amplify the sound and spread it farther. The use of the loudspeaker is very wide, such as teaching, tour guides, outdoors, speech activities, etc. There are many types of loudspeakers, such as hand-held, vertical or It is fixed. Usually, in order to make the sound of the loudspeaker spread farther, the sound source is usually extended in one direction. However, when it is necessary to spread the sound source in other directions, it is necessary to rotate the loudspeaker to extend the sound source. The direction of the sound source of the loudspeaker is converted, so as to achieve the effect of use. The existing hand-held and vertical loudspeakers usually need to manually adjust the direction, and the fixed type is difficult to adjust the direction, so that it is difficult to meet people's n...
