Sound source driving device based on fixed surface

Abstract

The invention discloses a sound source driving device based on a fixed plane, which comprises a fixed plane sound source driver, a connecting seat, a catching groove, an elastic buckle, a fixed seat, an upper triangular plate, a short support arm, a long support arm, a lower triangular plate, a storage box, a damping seat, a rubber cushion plate and a damping box, buckling grooves are formed in the four corners of the outer edge of the back face of the connecting base, elastic buckles are embedded in the buckling grooves and arranged at the four corners of the outer edge of the front face of the fixing base respectively, positioning grooves are formed in the four corners of the inner edge of the front face of the fixing base, and positioning columns are embedded in the positioning grooves and arranged at the four corners of the inner edge of the back face of the connecting base respectively; an indirect fixing mode is adopted, the problem of looseness after the fit clearance of screws and screw holes is increased is solved, the connection firmness is improved, falling is not likely to happen, the folding storage function is achieved, the occupied space is small, storage is convenient, and the transportation cost of the device is reduced.

Description

technical field [0001] The invention relates to the technical field of surface sound source drive devices, in particular to a fixed surface sound source drive device. Background technique [0002] A surface sound source is a vibrating body that radiates plane sound waves, and is a sound source that is often encountered in real life. The wave front of a surface sound source is parallel to the plane perpendicular to the propagation direction, and all points on the wave front have the same amplitude and phase, such as large-area walls that radiate low-frequency sound waves, vibration surfaces of large machinery and equipment, etc. As a surface sound source, it can be divided into two types: circular surface sound source and rectangular surface sound source. [0003] However, most of the existing fixed-surface sound source drive devices are directly fixed by screws. During disassembly and assembly, the matching gap between the screw holes is easy to increase, the connection is ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing fixed-surface sound source drive devices are directly fixed by screws. During disassembly and assembly, the matching gap between the screw holes is easy to increase, the connection is not firm, and it is easy to loosen and fall off. It does not have the folding function and cannot be stored. It takes up a lot of space and is inconvenient to store, which increases the transportation cost of the device. In addition, the anti-seismic performance is insufficient, it is greatly affected by ground vibration, the device shakes seriously, and the working reliability of the surface sound source is poor.
