Abstract
The utility model relates to a high-fidelity loudspeaker box casing, which belongs to the field of the loudspeaker box casing. A loudspeaker box is an integral lithoid box body. The size of a tri-frequency dividing box body is 600 * 218 * 266 (height * width * thickness), the bottom of the box body is provided with a technical cover, and the front side surface of the box body is provided with horn holes. The distance between the horn holes is the same as the central distance of a treble and a mediant horn holes, wherein, the centre distance is 145 m m, and the central distance of the mediant and a bass horn holes is 157 m m. The loudspeaker box casing approximates a rigid body, can make the original sounds really recovered particularly when large dynamic sounds play, does not generate standing waves, and has the advantages of broad sound field, accurate positioning and good on-site feeling. The outer surface of the box body which does not need to decorate has natural lithoid patterns, and meanwhile, the lumber can be saved and the forest resource is protected.
Description
The utility model relates to a kind of casing of loudspeaker box, special a kind of Hi-Fi sound-box shell.
At present, people are when making audio amplifier, generally all adopt timber to make, it is to become a cubical casing with six plank amalgamations, on the upright side of casing bellmouth orifice and paraphase hole are arranged, the back side is bonnet, pastes facing paper at the outer surface of casing, (high * wide * thick) of audio amplifier and the size relationship between adjacent two loudspeaker, the tonequality quality when directly having influence on its audio amplifier playback.Wherein, the box sizes of three frequency division is: 930 * 80 * 320 (high * wide * thick), and the centre-to-centre spacing in high pitch and mediant trumpet hole is: 120mm, the centre-to-centre spacing in middle pitch and bass horn hole is: 200mm; The two divided-frequency box sizes is: 323 * 185 * 260 (high * wide * thick), the centre-to-centre spacing in high pitch and bass horn hole is: 144mm.During the work of this audio amplifier, casing produces resonance with the sound of being play, and causes standing wave easily, and when playing the big dynamically sound, presence is poor, need use timber when making casing, can not protect forest resources.
The purpose of this utility model is will provide a kind of can not cause standing wave, the Hi-Fi sound-box shell that presence is good.
The purpose of this utility model is achieved in that audio amplifier is the whole casing of a stone matter, has technology lid in the bottom of casing.
Box sizes is: three frequency division:
600 * 218 * 266 (high * wide * thick), the centre-to-centre spacing in high pitch and mediant trumpet hole is: 145mm, the centre-to-centre spacing in middle pitch and bass horn hole is: 157mm, paraphase hole be in the behind of casing, the centre-to-centre spacing lower end 150mm in hole.
900 * 240 * 290 (high * wide * thick), the centre-to-centre spacing in high pitch and bass horn hole is: 145mm, the centre-to-centre spacing in middle pitch and bass horn hole is: 200mm, paraphase hole distance of center circle case top 160mm.
Two divided-frequency: 480 * 220 * 270 (high * wide * thick), the distance between the bellmouth orifice is: the centre-to-centre spacing in high pitch and bass horn hole is: 145mm, paraphase hole distance of center circle case top 160mm.
Because having adopted such scheme, its casing is the whole casing of a stone matter, is approximately one " rigid body ", so no matter be when playing the sound or the big dynamically sound, its sound all can not produce resonance with casing, does not have other clutter to amplify output from the casing quilt, thereby also just can not cause standing wave; Amplification to the sound is very true to nature, and presence is good, has reached the purpose of this utility model.This casing of loudspeaker box is similar to " rigid body "; when playing the sound; special when playing the big dynamically sound, the reduction strictly according to the facts of the original sound can not produced standing wave in the reduction process; sound field is broad; accurate positioning, presence is good, and box outer surface does not need to decorate and promptly has natural stone matter decorative pattern; simultaneously can save timber, protect forest resources.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Accompanying drawing is a structure chart of the present utility model.
Embodiment 1: audio amplifier is the whole casing of a stone matter, the three frequency division box sizes is: 600 * 218 * 266 (high * wide * thick), adopting special equipment upwards to draw from the bottom of audio amplifier digs, inner chamber or be cylinder or for cube, one technology lid 7 is arranged in the bottom of casing, there is bellmouth orifice positive side at casing 6, dorsal surface has wiring plate hole 5, distance between the bellmouth orifice is: high pitch 1 with the centre-to-centre spacing of middle pitch 2 bellmouth orifices is: 145mm, middle pitch 2 with the centre-to-centre spacing of bass 3 bellmouth orifices is: 157mm, the centre-to-centre spacing lower end 150mm in paraphase hole 4 holes.
Embodiment 2: three frequency division casing 6 is of a size of: 900 * 240 * 290 (high * wide * thick), distance between the bellmouth orifice is: high pitch 1 with the centre-to-centre spacing of middle pitch 2 bellmouth orifices is: 145mm, middle pitch 2 with the centre-to-centre spacing of bass 3 bellmouth orifices is: 200mm, paraphase hole 4 distance of center circle casees top 402mm, other and embodiment 1 omit together.
Embodiment 3: the two divided-frequency box sizes is: 480 * 220 * 270 (high * wide * thick), and the distance between the bellmouth orifice is: the centre-to-centre spacing in high pitch and bass horn hole is: 145mm, paraphase hole distance of center circle case top 160mm, other and embodiment 1 omit together.
