Description

Omnidirectional adjustable digital active ceiling loudspeaker Technical Field The utility model relates to the field of ceiling speakers, in particular to an omni-directional adjustable digital active ceiling speaker with adjustable sound directivity. Background In the audio application scene of modern architecture, the ceiling loudspeaker system, also called background music system, can create a uniform and comfortable hearing atmosphere in the indoor space by virtue of the ceiling loudspeaker system, and is widely applied to various places such as hotels, shops, office buildings, houses and the like. As a core component of the system, a ceiling speaker is typically composed of a combination of a high-pitched unit and a low-pitched unit. At the acoustic principle level, there is a close relation between the sound frequency and the directivity, the higher the frequency, the stronger the directivity. Therefore, the high-pitch unit shows stronger directivity characteristic in the sounding process. Conventional ceiling speakers are commonly installed in parallel to a ceiling or wall. This conventional mounting mode, while meeting basic sound propagation requirements to some extent, also results in significant limitations in the coverage angle of the speaker. In some places with wide space and complex structure, such as large conference rooms, exhibition halls and the like, part of areas are difficult to obtain good sound coverage, and sound dead angles exist, so that part of audiences cannot obtain ideal hearing experience. To solve the above problem of limited coverage angle, the skilled person proposes an improvement in which the treble unit is arranged to be steerable and the bass unit is kept stationary. Through the steerable high pitch unit, can be according to actual space layout and user demand, nimble adjustment sound propagation direction has effectively enlarged the coverage of high pitch part, has optimized whole audio to a certain extent. However, as the life of the ceiling speakers continues to increase, new problems become more pronounced. Through practical observation and professional tests, the bass unit of the ceiling loudspeaker is not only used for outputting low-frequency audio, but also used for emitting audio in a midrange in the working process. Because the design of the bass unit is not optimized for the midrange audio, the definition and layering sense of the sound are poor when the midrange audio is output, and the overall tone quality effect is further affected. Moreover, when the bass unit emits midrange audio, interference phenomenon is easy to occur in the space propagation process with the sound of the treble unit, so that the sound is distorted in a partial area, and the performance of the system is further weakened. In summary, although the existing ceiling speaker has advanced to some extent in the aspect of the steerable design of the high-pitched unit, the problem of outputting the midrange audio frequency of the low-pitched unit still makes the overall effect of the ceiling speaker defective, and it is highly desirable to further improve the performance of the system through technical innovation and optimization design so as to meet the continuous pursuit of people for high-quality audio experience. Disclosure of utility model The utility model has the advantages that the utility model provides the omni-directional adjustable digital active ceiling loudspeaker, the high-pitch unit and the low-pitch unit of the omni-directional adjustable digital active ceiling loudspeaker can be turned, a user can flexibly adjust the angles of the two units according to actual requirements, the optimal sound output effect is realized, the sound can accurately cover a required area, and the dead angle and interference of the sound are avoided. The omni-directional adjustable digital active ceiling loudspeaker has the advantages that the omni-directional adjustable digital active ceiling loudspeaker is rotated through the matching of the spherical arc surface of the inner shell and the spherical inner wall of the ceiling shell, the structure is simple and reasonable, and the design and manufacturing difficulty is reduced. The utility model further has the advantage that the omni-directional adjustable digital active ceiling loudspeaker is provided, and in the use process of the omni-directional adjustable digital active ceiling loudspeaker, the bass unit based on the spherical structure is convenient to steer and operate, and a user can easily adjust the bass unit to meet acoustic requirements of different scenes.
