Further, the connecting rod structure is a telescopic rotating structure.

Furthermore, the connecting rod structure is composed of a plurality of connecting rods which are sleeved with each other.

Further, each loudspeaker in the second sound box is arranged at different angles in the horizontal direction.

Furthermore, the up-down inclination angles of all the loudspeakers in the second sound box are different in size.

Further, the number of speakers in the second sound box is 6.

Furthermore, the connecting rod structure is detachably connected with the first sound box and the second sound box.

Furthermore, the connecting rod structure is in threaded connection with the first sound box and the second sound box.

In this application, each speaker of second audio amplifier sets to different angles, has enlarged the horizontal coverage angle and the perpendicular coverage angle of the sound field of second audio amplifier, and the sound field is more even, and is wider. In addition, the first sound box at the bottom and the second sound box at the top can be matched to increase the sound effect and the sound field coverage level.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. In the following description, specific details are provided, such as specific configurations and components, merely to facilitate a thorough understanding of embodiments of the invention. Thus, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

Referring to fig. 1 to 4, the speaker apparatus includes: a first sound box 10 positioned at the bottom, a second sound box 20 positioned at the top, and a connecting rod structure 30 connecting the first sound box 10 and the second sound box 20; wherein, the second sound box 20 includes: a box body 21, a mesh enclosure 22 and a plurality of loudspeakers 23; the mesh enclosure 22 is distributed with sound outlet holes 221; a cavity is formed in the box body 21, and a lateral opening for mounting the mesh enclosure 22 is formed in the lateral direction; the speaker 23 is accommodated in the cavity in a vertical direction; the speakers 23 are arranged at different angles.

It should be noted that the second sound box 20 is a sound column, and an inner cavity thereof includes a plurality of speakers 23 arranged along a vertical direction; the sound waves emitted from the speaker 23 may radiate outward through the sound outlet holes 221 formed in the mesh enclosure 22. In the embodiment of the present application, the speakers 23 are arranged at different angles, so that the horizontal coverage angle and the vertical coverage angle of the sound field of the second sound box 20 are enlarged, and the sound field is more uniform and wider.

In the present embodiment, the first enclosure 10 at the bottom may be configured as a subwoofer. The combination of a first enclosure 10 at the bottom with a second enclosure 20 at the top increases the sound effect and the level of sound field coverage.

In some embodiments, the mesh enclosure 22 has a sound-permeable plane 222 and two sides 223; the sound-transmitting plane 222 is provided with six deformed sound outlet holes 221. The shape of the sound outlet hole 221 is set to be six-deformed, so that attenuation of sound waves can be reduced.

In some embodiments, the linkage structure 30 is a telescoping and rotating structure. The relative distance and angle between the first sound box 10 and the second sound box 20 can be adjusted by the connecting rod structure 30, so that the sound box device can be adapted to more scenes. For example, in a scene that needs to cover different angles in front and back, the first sound box 10 and the second sound box 20 can be adjusted to corresponding angular directions through the connecting rod structure 30, so that the two sound boxes cover different horizontal angles, respectively.

In some embodiments, the link structure 30 is formed by a plurality of connecting rods sleeved with each other.

In some embodiments, each speaker 23 in the second enclosure 20 is disposed at a different angle in the horizontal direction. By arranging the speakers 23 at different horizontal angles, the coverage angle of the sound field of the second enclosure 20 in the horizontal direction can be increased.

In some embodiments, the pitch angles of the speakers 23 in the second enclosure 20 are different. By arranging the speakers 23 at different vertical angles, the coverage angle of the sound field of the second enclosure 20 in the vertical direction can be increased. For example, when the area to be covered includes upper and lower layers, the second sound box 20 may have better coverage for the audience of these upper and lower layers.

In some embodiments, the number of speakers 23 in the second enclosure 20 is 6.

In some embodiments, the link structure 30 is detachably connected to the first sound box 10 and the second sound box 20. During transportation, the whole sound box equipment can be disassembled into a plurality of parts, so that the transportation is convenient.

In some embodiments, the connecting rod structure 30 is screwed to the first and

second sound boxes

10 and 20.
