Problems solved by technology

It is time-consuming and labor-intensive to carry the speakers during site layout, and in most cases on the site, it is not suitable to use some means of transportation. The internal structure of the speaker itself includes some metal plates, which are heavy, which will cause a lot of inconvenience when using and operating.
[0003] In order to solve the above problems, according to the prior art, a retractable pull rod is generally provided on the back of the speaker and protrudes from the back or in the middle, but the pull rod is located on the back of the speaker and protrudes from the back. When the pull rod is pulled out and drags the speaker, The pull rod will bear a lot of weight. During the dragging process, the pull rod is easily deformed or even broken, so the load-bearing capacity of the pull rod is small; although the pull rod has a large load-bearing capacity in the middle of the speaker, when the speaker is dragged, the speaker is easy. It is very inconvenient to drag when it hits the person's heel
[0004] In addition, the speaker is generally equipped with a storage cavity for placing microphones and other items. According to the prior art, a drawer-type storage cavity is generally provided on one side of the speaker, and the other side of the storage cavity is a high-frequency In this way, when the size of the cabinet remains the same, the setting of the storage cavity makes the depth of the high-frequency speaker too small, and the sound quality of the high-frequency speaker is poor.

Abstract

The invention discloses a portable pull rod loudspeaker box. The portable pull rod loudspeaker box comprises a front box body (1), a rear box body (12), a power amplifier arranged in the rear box body (12) and a high-frequency speaker (2) arranged at the upper portions of the front box body (1) and the rear box body (12), wherein an outlet of the high-frequency speaker (2) is away from the rear box body (12), a telescopic pull rod (8) is arranged in the rear side of the rear box body (12) and located in the front box body (1), and rolling wheels (10) are arranged at the bottom of the rear box body (12) under the pull rod (8). The portable pull rod loudspeaker box further comprises a first groove (3) arranged in the rear box body (12) and located above the high-frequency speaker (2) and a second groove (6) connected with the first groove (3) and close to the pull rod (8), wherein the second groove (6) is deeper than the first groove (3). The portable pull rod loudspeaker box is large in pull rod bearing capacity and convenient to drag, and the moderate depth of the high-frequency speaker can be ensured, so that the quality of sound made by the portable pull rod loudspeaker box is good.
