Description

Height-adjustable sound column loudspeaker

Technical Field

The utility model relates to the technical field of sound, in particular to a sound column sound with adjustable height.

Background

The sound column sound box is a column sound box formed by arranging, combining and connecting a plurality of loudspeakers. Compared with the traditional sound box, the sound box has stronger sound directivity, smaller and exquisite appearance and small occupied area, and more accords with the concise style of modern home. Are commonly found in home theatres, conference halls, malls, gyms, bars, dining bars, schools, etc.

The utility model discloses a sound equipment support, which comprises a base, wherein a sleeve extending vertically upwards is arranged on the base, a supporting shaft is in sliding fit in the sleeve, a sound equipment is arranged at the upper end of the supporting shaft, and an adjusting mechanism for adjusting the axial sliding of the supporting shaft is arranged on the outer wall of the upper end of the sleeve; when the utility model is used, the height of the support shaft extending upwards is adjusted by rotating the handle, in particular, the handle is rotated clockwise to drive the gear to rotate, and the gear is meshed with the tooth groove surface at the bottom of the groove, so that the support shaft slides upwards due to the rotation of the gear, and when the support shaft slides to the required height, the second ring is screwed on the peripheral wall of the lantern ring, so that the handle is fixed

The above prior art has the following disadvantages: above-mentioned prior art can only use external cable to connect stereo set at top and bottom stereo set to it is inside to accomodate the integration to the support with the cable, and the cable of external cable can appear messy after stereo set and bottom stereo set are connected like this, influences whole pleasing to the eye, and because cable and support are the subdivision setting, need compromise cable connection and stereo set fixed in the stereo set assembly process at top, consequently assembly process is comparatively loaded down with trivial details.

On the other hand, the gear is fixed through the threaded connection of the first circular ring and the lantern ring, the operation is also complicated, the threaded connection of the circular ring and the lantern ring is easy to be confused with the rotation lifting operation of the handle, and a user cannot determine the correct operation and locking mode.

Disclosure of Invention

In order to solve the problems, the utility model provides the height-adjustable sound column loudspeaker which is convenient to assemble and simple in height adjustment.

In order to achieve the above purpose, the sound column sound with the adjustable height comprises a sound base, wherein a first sleeve is fixed on the sound base, a second sleeve is slidably matched in the first sleeve, a sound is assembled at the top of the second sleeve, a control end for controlling the height of the second sleeve is fixed outside the second sleeve, and the height can be adjusted by adjusting the overlapping length of the first sleeve and the second sleeve through the control end. The first sleeve and the second sleeve are matched to adjust the telescopic length, and a spiral spring wire for connecting the sound base and the sound is arranged in the second sleeve.

The further scheme is that an assembly hole is formed in the outer wall of the upper end of the first sleeve, and a tooth-shaped structure is arranged on one side of the second sleeve facing the assembly hole; the control end comprises a first gear and a second gear, the first gear is meshed with the second gear, the second gear is meshed with the tooth-shaped structure through an assembly hole, a rotating handle is assembled on one side of the first gear, a handle groove is formed in the rotating handle, a holding rod is arranged in the handle groove, a rotating point connected with the holding rod is arranged at one end, far away from the first gear, of the rotating handle, and the holding rod can rotate in the handle groove by taking the rotating point as an axle center. The structure is characterized in that a rotating handle and a holding rod for rotation are arranged on the first gear and meshed with the second gear, the second gear is meshed with the rack structure, the holding rod is rotated out of the handle groove when in use, then the second gear is rotated by operating the holding rod through the mechanism, and the second gear pushes the tooth-shaped structure to ascend or descend so as to change the height of the support. Through the transmission setting of two gears, can effectually utilize the required turning force of gear lift of transmission ratio reduction to guarantee that the stereo set can be steady lift. Meanwhile, the holding rod structure can be hidden in the holding rod groove, and the volume can be further reduced without using the holding rod structure.

And a fixing groove for placing the holding rod is formed in the side face of the second gear. When the sound column is lifted to the height required by a user, the holding rod is rotated 180 degrees by taking the rotation point as the axis, and then the holding rod is inserted into the fixing groove in an alignment angle, so that the first gear and the second gear can be locked, and the technical effect of fixing the height of the sound column sound is achieved.

A spiral spring wire is arranged inside the second sleeve; the bottom of the first sleeve is provided with a first connecting hole; the top of the second sleeve is provided with a second connecting hole; the two ends of the spiral spring wire are respectively connected with the first connecting hole and the second connecting hole. The arrangement of the first connecting holes and the second connecting holes at the two ends can simplify the sound connection process of the top and the bottom, the connection can be realized only by aligning the support with the interface on the sound base, the sound at the top is the same, and the arrangement is greatly convenient for the assembly of a user. And because the spiral spring wire is arranged in the cable, the whole connection can be completed only by connecting the sound at the top with the second sleeve, the tedious process of the external connection cable is reduced, and the problem of influence on the appearance caused by the exposed cable is avoided.

Compared with the sound assembly operation requiring an external cable and connection in the prior art, the sound column sound with the adjustable height simplifies the cable connection process of the sound and the bottom sound by accommodating and integrating the spiral spring wire for connection into the bracket, and the structure has no cable exposed after the assembly is completed, so that the overall sound aesthetic degree is improved by one grade, and the height adjustment and the fixation are easier due to the arrangement of the rotating handle and the rotatable grip.
