The sound column described in the document can adjust the height of the sound column by changing the installation direction of the sound column according to the actual use requirements, meet the use of personnel in different scenes, and ensure the playback effect.

[0004] In the existing sound box, in order to improve the low-frequency response and efficiency of the sound box, a reverse phase pipe is usually arranged on the sound box to realize the reverse phase of the sound. If the existing sound box in the above document is used, the connecting part needs to be avoided in the reverse phase pipe structure, which leads to the increase of the structure of the sound column, and the space utilization of the sound column is not high, or the reverse phase pipe is arranged on the back. In this way, the sound from the back of the loudspeaker needs to be conducted from the back to the front, which increases the sound conduction path. SUMMARY

[0005] The utility model provides a linear array sound column with high space utilization, which forms a reverse phase channel by using the installation slot and the installation part. Not only is the installation part installed, but also the reverse phase port can emit sound from the front without affecting the sound, so that the space utilization of the sound column is high.

[0006] In order to achieve the above-mentioned purpose, a linear array sound column with high space utilization rate comprises a sound column body, one or more than one loudspeaker arranged on the sound column body, a mounting groove arranged at the lower end of the sound column body, a mounting part arranged in the mounting groove, a cavity arranged inside the sound column body behind the loudspeaker, a reverse phase port arranged between the cavity and the mounting groove, an opening arranged at the front end of the mounting groove, and a reverse phase channel formed between the opening and the reverse phase port and between the peripheral part of the mounting part and the inner wall of the mounting groove.

[0007] The above-mentioned structure, by arranging the cavity inside the sound column body and communicating the cavity with the mounting groove through the reverse phase port, forms the reverse phase channel between the peripheral part of the mounting part arranged in the mounting groove and the inner wall of the mounting groove, so that the sound in the cavity can be emitted through the reverse phase port and the reverse phase channel, thereby facilitating the placement of the mounting part through the mounting groove and not affecting the sound emitted from the front of the cavity, so that the sound column has high space utilization rate.

[0008] Further, one or more than one loudspeaker is arranged along the upper and lower ends of the sound column body at the front end of the sound column body to form a linear array sound column, which has good sound emitting effect.

[0009] Further, an arc-shaped surface extending downward and outward from the top end of the sound column body to the bottom end of the sound column body is arranged at the front end of the sound column body, and the loudspeakers are arranged along the upper and lower ends of the arc-shaped surface to form an arc-shaped linear array structure. The arrangement of the arc-shaped surface makes the sound emitting angle of each loudspeaker different on the arc-shaped surface, thereby increasing the sound emitting range of the loudspeaker, so that the sound emitting effect of the sound column is better.

[0010] Further, a baffle is arranged at one end of the mounting groove close to the sound column body.

[0011] The above arrangement can block the sound emitted by the loudspeaker at the bottom of the arc-shaped surface, thereby preventing the sound emitting angle of the loudspeaker from being too low.

[0012] Further, reinforcing rib plates are arranged at both ends of the baffle and connected to both sides of the sound column body.

[0013] The above arrangement makes the connection structure between the mounting groove and the sound column body more stable through the arrangement of the reinforcing rib plates.

[0014] Further, an outer shell is arranged at the front end of the sound column body and the mounting groove, and the outer shell is a metal mesh plate structure.

[0015] The above arrangement can better protect the loudspeaker through the arrangement of the outer shell.

[0016] Furthermore, the mounting part includes a mounting post, which is disposed in a mounting groove. A positioning groove is provided on the mounting post, and a connecting post for connecting with the speaker is provided at the center of the positioning groove. The opening of the positioning groove is located at the bottom of the mounting groove.

[0017] The above settings, by including a positioning groove, facilitate the connection between the speaker column and the speaker enclosure's connecting rod.

[0018] Furthermore, a guide surface that is inclined downward and inward is provided at the top of the positioning groove.

[0019] The above design, through the guide surface, facilitates the insertion of the speaker's connecting rod into the positioning groove and fixing it to the connecting post. Attached Figure Description
