An angle adjustment mechanism and a sound box with the angle adjustment mechanism

Abstract

The invention discloses an angle adjusting mechanism and a loudspeaker box having the angle adjusting mechanism, wherein the loudspeaker box having the angle adjusting mechanism includes an angle adjusting positioning mechanism, and a bottom cover. The angle adjusting mechanism includes a housing, a support rod sleeve, a support rod, a limiting mechanism, and an angle positioning mechanism, wherein the limiting mechanism includes a stop structure and a rotating structure; the angle positioning mechanism includes at least one snap-fit structure disposed on the sidewall, and at least one abutting structure; the snap-fit structure includes a plurality of trapezoidal slots, and the abutting structure includes at least one positioning strip; the positioning strip includes a trapezoidal table; and the trapezoidal table is inserted into one of the plurality of trapezoidal slots when the support rod is inserted into the support rod sleeve to position the relative position of the support rod sleeve and the housing. Since the angle adjusting mechanism has the angle positioning mechanism and the limiting mechanism, the loudspeaker box may rotate around the pivot of the housing to adjust the angle of the sound under the mutual cooperation of the housing, the support rod sleeve and the support rod.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to an angle adjustment mechanism and a sound box with the angle adjustment mechanism. Background technique [0002] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate the sound energy to the space. It is an extremely important part of the audio system because it is responsible for converting electrical signals into A critical task of obtaining acoustic signals for the human ear to hear. Speakers have to deal directly with human hearing, which is very sensitive and has a strong ability to distinguish the timbre of complex sounds. Therefore, the arrangement of the sound field has a great influence on people's hearing enjoyment. [0003] In order to adapt to different usage occasions, one of the most commonly used methods to allow the sound propagation direction of the spe...

Problems solved by technology

However, in some large or medium-sized speaker application fields, such as cinemas, auditoriums, or performing arts spaces, when the speaker equipment is placed in a certain position, it is not necessary to adjust its direction frequently, and after adjustment, generally It will not be adjusted frequently, and most of the speaker adjustment structures in the prior art can be adjusted at any time, and there is no fixed structure, which makes such a speaker adjustment structure not suitable for large speakers, because the volume of large speakers Large, which will affect the quality of the output sound due to the vibration caused by the rotating structure in the prior art
