Abstract

The invention discloses an energy-saving type draw-bar acoustic device. The acoustic device comprises a shell, a movable block and a first spring; a high-pitch sound track is arranged on the surface of the shell, and a baffle plate is arranged at outside of the high-pitch sound track; rollers are arranged on the bottom of the shell, and a usb interface is arranged at one side of the shell, the movable block is arranged at the top of the usb interface, and a switch is arranged at one side of the movable block; a handle is arranged at the top of the movable block, and a limiting block is arranged at one side of the bottom of the handle; the first spring is arranged at the bottom of the handle, and a low-pitch sound track is arranged on the surface of the movable block, and a fixed block is arranged at the top of the low-pitch sound track; a second spring is arranged in the fixed block, and one side of the second spring is connected with a movable plate. The energy-saving type draw-bar acoustic device is convenient for holding the movable block part of the acoustic device, thereby preventing the movable block from occupying excessive space; and the storable handle is arranged at the acoustic device, so that the space can be saved.

Description

technical field [0001] The invention relates to the technical field of audio, in particular to an energy-saving pull rod audio. Background technique [0002] The trolley speaker is a kind of speaker that can be easily moved by pulling the rod. It is convenient for square dancing and commercial promotion. . [0003] However, the existing trolley speakers are not easy to move and store, take up more space, and cannot save energy. The sound emitted is too diffuse, resulting in energy waste. In view of the above problems, it is urgent to carry out innovative design on the basis of the original trolley sound system. Contents of the invention [0004] The purpose of the present invention is to provide an energy-saving trolley speaker to solve the above-mentioned background technology that is inconvenient to move and store, takes up a lot of space, cannot save energy, and the sound emitted is too diffuse, resulting in energy waste. [0005] In order to achieve the above object...
