Abstract
The utility model relates to an outdoor sound box with anti-resonance function. The sound box comprises a sound box front frame and a sound box body, wherein the inner wall of the sound box front frame is densely covered with honeycomb-shaped reinforcing ribs, and the inner wall of the sound box body is also densely covered with the honeycomb-shaped reinforcing ribs. The sound box has the advantages that: firstly, the sound box effectively improves the strength and rigidity of the sound box body and increases the thickness of the sound box body, and when the box body bears large dynamic audio signals, generated vibration is reduced to a negligible state, thereby ensuring good bass playback effect and mellow un-harsh timbre; and secondly, the arrangement of the honeycomb-shaped reinforcing ribs in the box body not only changes the air elasticity in the box body, but also improves sound damping property.
Description
Technical field
The utility model relates to a kind of outdoor audio amplifier that has intensity height, good rigidly, can effectively improve the sound dampening performance, and the dominant case is made the field.
Background technology
CN2620956Y, title " micro-pore wall integral type audio amplifier ", it mainly comprises casing, casing is provided with loudspeaker, internal wiring terminal is connected with loudspeaker by connecting line, internal wiring terminal is connected with outer terminal by frequency divider, and the as a whole structure of casing is distributed with micropore on the casing, box inside is provided with sound absorbing layer, also is provided with phase-reversing tube on the casing.Its weak point: the design of micropore on the box body wall, not only reduced the intensity of casing itself, and because the micropore on the box body wall directly faces is sound absorbing layer, do not had sound-absorbing and standing wave elimination preferably at all.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design and a kind ofly can either improve casing intensity, can improve the sound dampening performance again effectively and change the flexible outdoor audio amplifier of air in the casing body.
Design: in order to realize above-mentioned purpose of design.The utility model is on the basis of existing sound box, and on structural design, the evenly densely covered cellular reinforcement of the inwall of sound box front plane frame and the inwall of sound box is a major technique feature of the present utility model.The purpose of doing like this is: the one, and the setting of the cellular reinforcement of inwall of the inwall of sound box front plane frame and sound box, not only increase the thickness of sound box, improved the intensity and the rigidity of sound box structure effectively, and when making woofer in the audio amplifier be in big dynamic audio frequency signal to play, the vibration that its sound box produced has dropped to the very little state of disregarding of minimum-----reached, not only guaranteed ultralow acoustic realization, and made sound can obtain reducing more truly; The 2nd, cellular reinforcement in sound box evenly gathers, not only increased the surface area of box house widely, avoided effectively because sound superposes, disturbs the more crests and the trough that are occurred on the caused frequecy characteristic curve, and changed the interior air elasticity of casing body effectively, greatly improved the damping capacity of sound.Its technical scheme: outdoor audio amplifier, it comprises audio amplifier front plane frame and sound box, the inwall of described audio amplifier front plane frame and sound box inwall are densely covered with cellular reinforcement respectively.
The utility model is compared with background technology, the one, the setting of the cellular reinforcement of inwall of the inwall of sound box front plane frame and sound box, increased the thickness of sound box, the intensity and the rigidity of sound box have been improved effectively, make sound box when bearing big dynamic audio frequency signal, the vibration that is produced has dropped to the state of disregarding that has reached very little, and not only the bass playback is effective, and tone color is mellow and full, and is not dry and astringent; The 2nd, the setting of cellular reinforcement in the casing has not only changed the elasticity of air in the casing body, and has greatly improved the damping capacity of sound.
Description of drawings
Fig. 1 is the structural representation of outdoor audio amplifier front plane frame.
Fig. 2 is the structural representation of outdoor sound box.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.Outdoor audio amplifier, it comprises audio amplifier front plane frame 2 and sound box 3, audio amplifier front plane frame 2 inwalls are densely covered with cellular reinforcement 1 (generally being equipped with cellular reinforcement 1 at audio amplifier front plane frame back side of panel), sound box 3 inwalls are furnished with cellular reinforcement 4 (the general back side and side in sound box is equipped with cellular reinforcement 4), cellular reinforcement adopts high-density plastic's injection mo(u)lding, and the high-density plastic is made of the composite material of high molecular polymer and high density mineral.Audio amplifier front plane frame 2 and sound box 3 adopt mold injection molding.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection range of the present utility model.
Claims (2)
