Description

Technical Field

[0001] The utility model relates to the technical field of sound box equipment, in particular to a line array sound box which is convenient for hanging. Background Art

[0002] A speaker is a device that converts audio signals into sound. It is the terminal of the entire sound system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is often used in indoor places such as homes, dance halls, KTVs, theaters, etc. Nowadays, people use speakers not only indoors, but also outdoors or in large squares. Since the outdoor venue is open and boundless, the sound of conventionally arranged speakers cannot cover the entire venue. Therefore, people arrange a group of speakers vertically to form a line array speaker, so that each speaker has a cone-shaped radiation space. The sound pressure of these cone-shaped spaces is squeezed accordingly to form a horizontal elliptical overlapping space, which can cover a wider area.

[0003] In order to arrange these line array speakers vertically, people have to set up multi-layer brackets and place multiple line array speakers layer by layer. Such multi-layer brackets are not only costly, but also bulky and inconvenient to move. In addition, the line array speakers placed on the shelves are placed in parallel, and the angle of the speakers cannot be adjusted as needed. There are also some line array speakers that are hung on racks. Multiple line array speakers are connected in series through chains and then connected to the racks. This connection method is simple and convenient, and the racks do not take up transportation space, but the line array speakers connected by chains are easy to fall off, and the angle of the line array speakers is not easy to adjust. In addition, when the line array speakers are placed on the ground or stacked on a table, the chains do not provide any support. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned prior art and provide a line array speaker which is convenient to hang and has adjustable angle.

[0009] The accommodating groove can be used to accommodate the hanging parts. When the line array speaker is not needed, the hanging parts can be hidden. When it needs to be connected, the hanging parts only need to be rotated into the accommodating groove of another line array speaker and then connected by a pin.

[0010] Preferably, the pin hole extends along the height direction of the hanging component, and its width dimension gradually decreases from bottom to top.

[0011] After such arrangement, the first hinged part of the line array speaker can be hinged to the second hinged part of the line array speaker above it, and then the upper line array speaker is released. Under the action of gravity, the bottom of its rear end will abut against the top of the lower line array speaker; then the hanging part of the lower array speaker is rotated to the receiving slot of the upper line array speaker; then the pin is inserted into the appropriate hanging hole; the entire connection process does not require continuous lifting of the upper line array speaker, and only requires lifting the upper line array speaker after the connection is completed. Under the action of gravity, the upper end of the pin will automatically abut against the top of the pin hole.

[0012] Preferably, a positioning groove is provided on the top of the hanging component, and a positioning pin is connected to a hanging hole corresponding to the positioning groove on a hanging base plate of another line array speaker, and the positioning pin is clamped in the positioning groove.

[0013] Since the pin hole extends along the height direction of the hanging piece, although this arrangement is convenient for hanging the line array speakers, when the line array speakers are stacked on the ground or on a table, the upper line array speaker will fall due to gravity, resulting in the problem that the relative angle of the two line array speakers cannot be fixed; therefore, a positioning groove is provided on the top of the hanging piece, and a positioning pin is connected to the hanging hole corresponding to the positioning groove. When the upper line array speaker falls due to gravity, the upper line array speaker will be supported by the cooperation of the positioning groove and the corresponding positioning pin, thereby achieving the purpose of fixing the relative angle of the two line array speakers.
