Abstract
A natural stone sound box belongs to sound equipment. It is composed of a box body, a loudspeaker, a frequency divider and sound absorption cotton. The box body is made of agate, granite or marble. The lower part of the baffle plate of the box body is fixedly connected with a stone plate-shaped or wedge-shaped resonance suppression body, and two sides of the baffle plate are fixedly connected with two resonance suppression ribs. It has large damping coefficient and good rigidity, can effectively inhibit resonance, standing wave, interference, acoustic short circuit and other phenomena, greatly improves fidelity and bandwidth, and makes bass full and pure, and treble and clear. Can be widely applied to sound equipment such as home theaters, combined sound equipment, multimedia computers and the like.
Description
The utility model relates to sound appliances, more particularly belongs to the natural stone material sound box of sound appliances such as being used for home theater, combination audio, multimedia computer, cinema, broadcasting studio.
It is wooden that traditional audio amplifier mostly is greatly.Wooden audio amplifier is because the rigidity of timber is little, and damping coefficient is little, and when the loud speaker sounding vibrated, casing easily produced nuisance vibration.These nuisance vibrations and sound wave stack often produce interference, resonance, standing wave, cause acoustic short circuit, linear distortion and high order harmonic component distortion.The easiest generation low-frequency resonant of lower box, it makes audio amplifier carry dull rumble secretly in powerful bass, causes the serious distortion of low frequency and narrowing down of frequency response.For eliminating these nuisance vibrations, No. 98233990.9 Chinese patent application are designed to double-decker with the bottom of audio amplifier, make it to form a cavity, fill cast iron sand or the river sand of Φ 2~Φ 4mm in the cavity.It is comparatively complicated that this resonance suppresses the system fabrication technique, and cavity is because of loading the discontented resonance of also can empathizing, and cast iron sand or river sand also tend to produce husky ring vibration.Thereby still can not eliminate nuisance vibration ideally.
The purpose of this utility model is to overcome above-mentioned defective and deficiency, and a kind of damping coefficient and rigidity that both can improve tank material is provided, and suppresses nuisance vibration from selection; Improve the structure of sound box again, suppress nuisance vibration, thereby improve the fidelity of audio amplifier and the natural stone material sound box of frequency response width from structure.
In order to achieve the above object, the casing that forms by being connected of the utility model with baffle, biside plate, back shroud, top board and base plate, be installed in the loud speaker that is positioned at casing on the baffle, the frequency divider that links to each other with speaker, liner and formed at the sound-absorbing material of interior.Casing is made by lithotome.The bottom of the baffle resonance that is being connected suppresses body.Resonance suppresses body to be made by lithotome equally, is wedge-like tabular or that thickness is up-small and down-big, and its inclined-plane is positioned at the baffle inboard.Lithotome density is big, rigidity is high, and is big to the damping coefficient of sound.Make casing with lithotome, also just significantly reduced nuisance vibration.Adopt tabular or wedge-like resonance suppresses body and is connected in the baffle bottom, can more effectively suppress nuisance vibration.And after this resonance that is connected suppressed body, the stone material of making casing and baffle is attenuate suitably, with weight reduction.The resonance of wedge-like suppresses body increases the thickness of baffle bottom gradually, and its rigidity also increases gradually, and the effect of shaking clearly can be better.
The lithotome kind is a lot, and effect is fine when making casing with fine and close stone material such as agate, granite and marble.Crack, gap are bigger, and density is less, the stone material that structure is big and loose, and the weakening effect is relatively poor.In the granite, best with careful closely knit effects of structure such as Jinan green grass or young crops, Indian red, African Reds, and also outward appearance is magnificent.
The baffle both sides lithotome system resonance that two cross sections that are arranged above and below are rectangle that also can be connected suppresses muscle.It can improve the damping coefficient and the rigidity of baffle greatly, further suppresses the nuisance vibration of baffle, comprises resonance and standing wave.
Task of the present utility model comes to this and finishes.
The utility model is improved from material and two aspects of body structure, has improved the rigidity harmony damping characteristic of casing greatly, has suppressed nuisance vibrations such as resonance, standing wave, interference effectively, has reduced distortion, has improved the fidelity and the frequency bandwidth of audio amplifier.And its outward appearance is returned Piao and is returned very, luxurious elegance.Compare with the wooden audio amplifier in past, its fidelity and frequency response all are significantly improved.It can be widely used in the stereo sets such as home theater, combination audio, Karaoke, multimedia computer, broadcasting studio, cinema.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
Fig. 1 is the cross-sectional schematic of the utility model embodiment 1.
Fig. 2 is the A--A cutaway view of Fig. 1.
Illustrated in figures 1 and 2, embodiment 1 by with baffle 1, biside plate 2, back shroud 3, top board 4 and base plate 5 bonding be connected form casing, loud speaker 6, frequency divider 7, sound-absorbing material---acoustical cotton 8 is formed.Casing is made by natural granite Jinan green grass or young crops.The bottom of baffle 1 bonding resonance suppress body 9, it be up-small and down-big wedge-like, still by the blue or green making in Jinan.The baffle two-side adhesive two resonance that are arranged above and below and is suppressed muscle 10, and it is also made by Jinan is blue or green.11 is paraphase hole.Embodiment 1 is a Hi-Fi sound-box, is used for multimedia computer, and tonequality is good, and distortion is few, and frequency response is the 45--18000 hertz.
Claims (3)
1, a kind of natural stone material sound box, the casing that it forms by being connected with baffle, biside plate, back shroud, top board and base plate, be installed in the loud speaker that is positioned at casing on the baffle, the frequency divider that links to each other with loud speaker, liner and formed at the sound-absorbing material of interior, it is characterized in that said casing made by lithotome, the bottom of the baffle resonance that is being connected suppresses body, resonance suppresses body and is made by lithotome equally, be wedge-like tabular or that thickness is up-small and down-big, its inclined-plane is positioned at the baffle inboard.
2,, it is characterized in that said lithotome is agate, granite or marble according to the described natural stone material sound box of claim 1.
3, according to claim 1 or 2 described natural stone material sound boxes, the lithotome system resonance that it is characterized in that also being connected at said baffle both sides two cross sections that are arranged above and below are rectangle suppresses muscle.
