Further, described casing has cavity, is provided with two baffle plates that described cavity can be divided into three chambers in the described cavity.
Further, be respectively equipped with a woofer on described two baffle plates.
Further, described two woofers and wherein said two chambers constitute described bass bugle.
Further, described middle pitch bugle is positioned at the centre of described two woofers, and described middle pitch bugle is positioned on the axis of described bass bugle.
Further, described Horn is installed on the axis of described middle pitch bugle.
Further, the sounding passage of described middle pitch bugle is positioned at the both sides of described Horn.
Further, the sounding passage of described bass bugle is positioned at the both sides of described middle pitch bugle.
Further, described Horn and described middle pitch bugle constitute the coaxial big bugle of an alt, and the coaxial big bugle of described alt is positioned at the centre of described bass bugle.
Further, described Horn is consistent with the projecting direction of described middle pitch bugle, and the incident line of described Horn and described middle pitch bugle is same axis.
Compared with prior art, the three frequency division audio amplifier of the unified bugle of the utility model the frequency axis of propagating be same axis, synchronous transmission, accurate positioning has guaranteed that the acoustic centres axis of high, medium and low sound is the same line, and the propagation phase fidelity of high, medium and low sound gamut sound is high, and the position separately of sounding also is difficult for chaotic, sound is Clear ﹠ Transparent, thereby has solved the problem of phase deviation, avoids sound to cause confusion.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Fig. 1 and Fig. 4, the utility model has disclosed the three frequency division audio amplifier 1 of a bugle of a kind of unification, comprise casing 11, be provided with bass bugle 111, middle pitch bugle 112 and Horn 113 in the described casing 11, described middle pitch bugle 112 is positioned at the centre of described bass bugle 111, and described Horn 113 is positioned at the centre of described middle pitch bugle 112.
See also Fig. 1 and Fig. 2, described casing 11 has cavity 114, is provided with two baffle plates 116 that described cavity 114 can be divided into three chambers 115 in the described cavity 114.Described three chambers 115 are respectively first chamber 1151 and second chambers 1152 that is positioned at described casing 11 relative both sides, and the 3rd chamber 1153 that roughly is positioned at described casing 11 central authorities, described first chamber 1151 and described second chamber 1152 are symmetrical arranged with respect to described the 3rd chamber 1153.Described baffle plate 116 comprises the diaphragm plate 1161 on the sidewall 117 that is vertically installed in described casing 11, and connects and the relative inclined clapboard 1162 that it is obliquely installed with described diaphragm plate 1161.
See also Fig. 1, Fig. 2 and Fig. 3, be respectively equipped with a woofer 118 on the described inclined clapboard 1162 of described two baffle plates 116, described two woofers 118 constitute described bass bugle 111 with wherein said first chamber 1151 and described second chamber 1152.Described middle pitch bugle 112 is positioned at the centre of described two woofers 118, and described middle pitch bugle 112 is positioned on the axis of described bass bugle 111, and the sounding passage of described bass bugle 111 is positioned at the both sides of described middle pitch bugle 112.Described Horn 113 is installed on the axis of described middle pitch bugle 112, and described Horn 113 is consistent with the projecting direction of described middle pitch bugle 112, and the incident line of described Horn 113 and described middle pitch bugle 112 is same axis.Simultaneously, the sounding passage of described middle pitch bugle 12 also is positioned at the both sides of described Horn 113.Described Horn 113 and described middle pitch bugle 112 constitute the coaxial big bugle 119 of an alt, and the coaxial big bugle 119 of described alt is positioned at the centre of described bass bugle 111.
