The utility model is to constitute like this, it comprises sound box, be located at the speaker unit in sound box front, return port and voicefrequency circuit device, it is characterized in that: be provided with vertical first a sinuous flow combing plate that connects sound box top panel and lower shoe at the inboard position of sound box, be respectively equipped with a back-lash plate of diffraction sound in the both sides of the first sinuous flow combing plate near the centre.
The utility model is compared with existing in the world pair of low frequency full-range cabinet at present, has the following advantages:
1, owing to adopts sinuous flow combing design, so the backward radiation sound wave that speaker unit produces is through the combing of sinuous flow combing plate, not only can eliminate the sinuous flow ripple that two low frequency backward radiation sound waves produce, and can eliminate the backward radiation sound wave and directly produce to resonate and cause the narrow defective of audio amplifier frequency response range, thereby the response frequency and the tone color definition of audio amplifier have been improved with the sound box effect.
2, owing to be provided with the back-lash plate of diffraction sound,, make audio amplifier have abundant low-frequency effect, thereby improved the audio quality of sound equipment so collide the principle that can produce subresonance mutually according to the diffraction sound of architectural acoustics in the sound box inboard.
3, the utility model is rational in infrastructure, not only has the remarkable advantage that tone color is clear, stereovision is clearly demarcated, the audio amplifier low frequency linear displacement of using the speaker unit of same caliber size to make can descend more than 30%, its acoustical quality is taken the course of its own at present international similar audio amplifier with the domestic market, and have the cost performance height, and the remarkable advantage that effect is good, its cost is identical with domestic audio amplifier of the same type, but, thereby consumption value and use value have been improved greatly far below external like product.

Fig. 1 is the front organigram of sound box.
Fig. 2 is that the back-lash plate of the utility model embodiment one diffraction sound vertically is arranged on the organigram near both sides, sinuous flow combing plate 1 centre position.
Fig. 3 is that the back-lash plate of the utility model embodiment two diffraction sound vertically is arranged on the organigram near sinuous flow combing plate I tip position both sides.
Fig. 4 is that the back-lash plate of the utility model embodiment three diffraction sound vertically is arranged on the organigram near sinuous flow combing plate I bottom position both sides.
Fig. 5 is the internal structure schematic diagram of the utility model embodiment four sound boxes.
Among the figure, 1 is sound box, and 2 is return port, and 3 is the first sinuous flow combing plate, 4 is the second sinuous flow combing plate, and 5 is the back-lash plate of diffraction sound, and 6 is tweeter, and 7 is mid frequency ludspeaker, 8 is woofer, and 9 is the top panel of sound box, and 10 is the lower shoe of sound box.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments of the present utility model pair of low frequency full-range cabinet is described further.
With reference to Fig. 1, Fig. 2, the utility model embodiment one comprises sound box 1, is located at the speaker unit in sound box 1 front, return port 2 and voicefrequency circuit device, it is characterized in that: be provided with vertical first a sinuous flow combing plate 3 that connects sound box top panel 9 and lower shoe 10 at sound box 1 inboard position, be respectively equipped with a back-lash plate 5 of diffraction sound in the both sides of the first sinuous flow combing plate 3 near the centre.The back-lash plate 5 of above-mentioned diffraction sound is the both sides that vertically are arranged near the first sinuous flow combing plate, 3 centre positions.
With reference to Fig. 3, the utility model embodiment two is that the above-mentioned back-lash plate 5 of diffraction sound can be the both sides that vertically are arranged near the first sinuous flow combing plate, 3 tip positions.
