CN2286947Y - Full-glass artistic-lamp voice box with internal structure of semi-circular tube - Google Patents

Abstract

The utility model relates to a semicircular pipe-shaped full-glass artistic lamp sound box with an inner structure. A bent glass slice and a sound absorption sponge are fixedly connected between the front part of a back baffle plate of a glass box plate and two lateral plates. A loudspeaker is fixed on a front baffle plate of a glass box body in which an artistic lamp is also arranged. The utility model has the advantages that the utility model can effectively prevent the sound box from coloration and can avoid the interference from standing waves; the fidelity of sound quality is good; compared with a wooden sound box, the performances for resisting moisture, mildew and borers are better.

Description

The full glass art lamp of inner structure semi-circle tubular audio amplifier

The utility model relates to the auxiliary equipment of physical field a kind of stereo set, particularly a kind of music.

Existing audio amplifier is the seamed edge cuboid of wooden structures, although wherein be no lack of high-quality position audio amplifier, but all can not fundamentally solve audio amplifier dyeing, the resonant stationary wave problem, be respectively axial oscillations because occur in the resonance of audio amplifier inside, tangential resonance, oblique resonance, wherein axial oscillations is to produce the maximum vibration source that standing wave disturbs, the reason that standing wave produces is the stack of the incident wave that occurs between two parallel surfaces of cuboid audio amplifier of sound wave and reflected wave and forming, in addition, the material local oscillation frequency (between the 20HZ-100HZ) of wooden (being solid organic matters) audio amplifier wall overlaps with the audio amplifier bass, thereby generation resonance, and even the bass that audio amplifier takes place not is the pure bass that loud speaker sends, the dyeing case sound that is sending when the inside is being mingled with the audio amplifier vibration, lose hi-fi, the wooden acoustic box humidity resistance is poor simultaneously, easily goes mouldy, easily damage by worms.

The purpose of the utility model is to provide a kind of overcome audio amplifier dyeing, resonant stationary wave, fidelity is good, moistureproof and mildewproof the is mothproof novel audio amplifier-full glass art lamp of inner structure semi-circle tubular audio amplifier.

Technical solution of the present utility model is: the full glass art lamp of this inner structure semi-circle tubular audio amplifier has the glass casing, loud speaker is fixed on the preceding baffle of glass casing, be connected and fixed bend glass sheet and sound-absorbing silk floss between the back baffle of glass casing and biside plate, the sound-absorbing silk floss is attached on the bend glass sheet and is connected and fixed, and artistic lamp also is housed in the glass casing.

The utility model is compared with prior art, adopts the glass of solid inorganic thing to have incomparable superiority and moistureproof and mildewproof insect resistance than other solid organic matters materials.Because the natural mode shape of fixed inorganic thing is in the infrasonic sound section, so make casing with glass, can not resonate with the loud speaker low frequency, avoid occurring sound equipment dyeing, adding the big density and the high-quality of glass, all be that wooden acoustic box is incomparable, and transparent casing is loaded onto artistic lamp, increased artistic treat, unified with audiovisual more than one the case.Before the baffle of back bend glass and acoustical cotton are housed in the prior glass casing, this inner structure adopts semi-circle tubular to make sound have well flow direction property, the semicircle wall energy at rear portion seamlessly transits sound, can effectively eliminate the influence that standing wave disturbs and the box house natural reonant frequency is brought, also can eliminate simultaneously the diffraction and the pulse loudness defect of bad of sound each seamed edge in rectangular box in a large number, therefore the utility model is good to acoustic fidelity, high pitch is clear and melodious bright melodious, the middle pitch true nature, bass is abundant, and is true strong, and overall sound quality is extremely pure true, the tone color grace, the range broadness has significant music effect.
