Abstract
The utility model relates to a sound box which mainly solves the problems that the performance of a sound box of the prior art for resisting standing waves and resonant interaction is poor. The utility model is characterized in that an inner cavity of a box body is cylindrical; a plurality of groups of tooth-shaped convex parts which are mutually staggered are arranged in the inner cavity of the box body. The utility model has the advantages of reasonable structure, convenient fabrication, strong performance for resisting interference, clear and pure sound quality, quick transient response and sufficient bass elasticity. The utility model is an ideal structure of a high-fidelity sound box and can be widely used by various sounding devices.
Description
The utility model relates to a kind of parts of transducer, particularly a kind of audio amplifier that is used for stereo set.
The audio amplifier that prior art is used is the shortcoming of the audio amplifier tonequality decline that solves interference such as anti-standing wave and resonance and bring, generally adopt and change the audio amplifier shape, physical dimension, or in audio amplifier, set up technological means such as sound-absorbing material, though the prior art means play certain good effect in the certain frequency section, be difficult to thoroughly solve the interference of standing wave and resonance, particularly standing wave and disturb, because the audio amplifier that prior art is used can't thoroughly solve interference such as standing wave, so general tonequality is relatively poor.
The purpose of this utility model is that design is a kind of rational in infrastructure, easily manufactured, can effectively control and remove interference such as standing wave and resonance, improves the novel audio amplifier of audio amplifier tonequality.
The purpose of this utility model is to realize like this, the sound intracoelomic cavity adopts cylindrical cavity, the casing employing stacks along the axis direction multilayer and forms, on every layer of inner chamber circumference of casing, be provided with toothed projections, every layer of toothed projections of casing staggers mutually, adopts sealing bonding between every layer of the casing, box shape can adopt Any shape, and casing also can adopt overall structure.
Below in conjunction with accompanying drawing the utility model is described:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is accompanying drawing 1 cut-away view.
With reference to the accompanying drawings, sound box 1 inner chamber adopts cylindrical cavity, and owing to the reflected wave that does not exist the axial propagation between two parallel surfaces to cause in the casing 1 and the superposition phenomenon of incident wave, promptly standing wave disturbs.Cylindrical cavity is not influenced by loud speaker 3 auxilliary fluctuation pressures of penetrating sound basically simultaneously, casing 1 is difficult for deforming, and effectively controlled the influence of resonance, disturb for reducing resonance, be convenient to processing and manufacturing, casing 1 adopts multilayer to stack structure along axis direction, on the casing 1 inner chamber circumference, be provided with multilayer toothed projections 2, and every layer of toothed projections 2 staggers mutually, owing to adopt said structure, make interior incident wave of audio amplifier and reflected wave form with incoherent scattering and diffraction, allow the sound wave wave energy after the high order refraction, under very short situation of reverberation time, be full of whole audio amplifier inside equably, the standing wave of generation is eradicated substantially, multiple sets of teeth shape projection 2 has formed the system of a complete anti-external and internal pressure, increased audio amplifier anti-resonance vibration ability, multiple sets of teeth shape projection 2 has the feature that absorbs sound preferably simultaneously, and can play sound absorption in different frequency bands, for increasing the sealing property of audio amplifier, casing 1 adopts between every layer sealing bonding, when guaranteeing that the audio amplifier inner-cavity structure is constant, casing 1 profile can adopt Any shape, and casing 1 also can adopt not stratified overall structure according to different processing methods.
The utility model proves through embodiment, have rational in infrastructure, easily manufactured, anti-standing wave, the anti-resonance vibration ability is strong, audio amplifier sound clarity, pure, and transient response is fast, bass elasticity foot is a kind of comparatively desirable Hi-Fi sound-box structure, can be widely used in the use of various sound equipments.
