The circle drum sound box is made of casing and support two parts, and support is one to fall " 7 " font, and the tone chamber is the ellipsoid shape space that curved surface constitutes, and casing and support are jointless overall structures.

Promptly can be made into one according to such scheme is the overall structure sound box bodies of raw material with the stone material.Can be made into all styles of, the casing of a plurality of loudspeaker units according to the design needs.Box outer surface is done polishing, make its smooth cleaning,, load onto loud speaker and corresponding signal of telecommunication wiring, just become a stone carving audio amplifier that is good for sound at panel upper speaker installing port place.Handle if on each face of casing, make some traditional stonework patterns, will have better use value.

The utility model has the advantages that and adopt stone material integral body to be processed into, reduce the tonequality,, avoided the bonding imprecision of polylith panel material to influence the problem and the unstable weakness of tonequality owing to be overall structure except not causing noise resonance; Thereby better rigidity and sealing are arranged, bear aspect high-power, low distortion and the transient response all more outstanding.The audio amplifier inner chamber is faced the wall and meditated and is made of curved surface, there is behind the interests loud speaker enhancing be not fully exerted to the resonance of sound wave, each tone chamber's inwall of inner chamber in the course of processing owing to chisel technology, formed the curved surface that constitutes by the irregular polygon facet, it is favourable heat absorption, the point in the sound wave of helping again decaying the rapidly composition of making an uproar overcomes its interference, avoids it to influence tonequality and has played important function; Also because the spherical structure of tone chamber has avoided four jiaos of storage power of rectangle audio amplifier to disturb the problem of tonequality.Thereby tonequality can obtain to increase substantially.Relative wooden acoustic box, also to have reduced those be the additional facilities that prevents that harmful resonance of casing self from taking textural, thereby can reduce material consumption, simplify operation.So the integrally-built audio amplifier of stone material is the more superior stereo set of a kind of acoustic mass, extensively is suitable for family and various public place of entertainment and uses.
