Embodiment Construction

[0015] Such as Figure 1-Figure 3 As shown, the loudspeaker with variable orientation includes a cylinder 1 with an opening at one end of the cylinder 1 , and several horns 5 are evenly distributed and hingedly arranged on the end surface of the opening of the cylinder 1 . A slide plate 3 is fixedly arranged in the middle of the cylinder body 1 , and the slide plate 3 is provided with banner-shaped limiting grooves 10 corresponding to the number of horns 5 . A guide plate 2 is provided for rotation at the inner bottom of the cylinder body 1 , and a slideway 9 is provided on the guide plate 2 .

[0016] The slideway 9 is spliced ​​by two interconnected grooves, one of which has a semi-elliptical structure and the distance between its midpoint and the center of the guide plate 2 is smaller than any end of the groove and the center of the guide plate 2 The other section of the groove is a semi-elliptical structure and the distance between its midpoint and the center of the guide...

Abstract

The present invention relates to a loudspeaker, in particular to a variable orientation loudspeaker and its usage method. Speakers with variable orientation, a number of speakers are evenly distributed on the opening end of the cylinder, a slide plate is installed in the middle of the cylinder, a guide plate is installed at the bottom of the cylinder, and banner-shaped limiters corresponding to the number of speakers are arranged on the slide Slot, guide plate is provided with slideway, slideway is provided with the hinged seat of pull rod corresponding to the number of horns, one end of pull rod is hinged to the hinged seat of pull rod, and pull rod passes through the limit groove and is hinged with the side wall of horn. Rotating the direction of the guide plate can realize the corresponding speaker facing the required direction, and realize the sound effect of sound transmission to the crowd in different directions.

Description

technical field [0001] The present invention relates to a loudspeaker, in particular to a variable orientation loudspeaker and its usage method. Background technique [0002] The loudspeaker is commonly known as the horn, an electrical device that converts electrical energy into sound, and transmits electrical energy of different sizes to the coil. The coil generates magnetism and interacts with the magnet, causing the diaphragm to vibrate. Because the magnitude of the electrical energy is different, the vibration of the diaphragm is caused. The frequency and amplitude are constantly changing, so that the effect of the diaphragm on the air is constantly changing, forming a rich sound. [0003] Currently, the loudspeakers are installed in a fixed manner, and the sound emitting part of the loudspeaker faces a specific direction. In the face of different scene conditions, it is necessary to adjust the orientation of the speaker. If no adjustment is made, the ideal sound effect...
