Abstract
The utility model provides a double tube shape sound box. The utility model can lengthen the traveling distance of gas stream, improve low frequency response, increase basetone reverberation time, reduce the influence of the sound box body standing wave on the tone quality and improve the sound resolution ability and fidelity. The utility model comprises a high tone loudspeaker 1, a bass loudspeaker 2 and a guiding tube, the high tone loudspeaker 1 is arranged in a circular pipe, a bass loudspeaker is arranged in the other circular pipe whose diameter is larger than the diameter of the circular pipe, the other circular pipe is arranged below the circular pipe, and the joining part of the two circular pipes are provided with a guiding hole 4.
Description
The utility model provides a kind of audio amplifier of shaped double tube.
It is a lot of to influence acoustic factor, as the propagation distance of acoustic pressure air-flow, the geometry of sound box etc.Audio amplifier commonly used at present is generally rectangle, exists Stationary Wave in this audio amplifier, and because the propagation distance of sound wave equals the distance of audio amplifier front and back panel, so its tone color is affected.
The utility model is intended to overcome above-mentioned defective, provides a kind of and makes the air-flow propagation distance increase, can improve LF-response, increases the audio amplifier of bass reverberation time, and reduce the influence of sound box standing wave to tonequality, and that improves sound separates clear ability and fidelity.
For this reason, the utility model provides a kind of shaped double tube audio amplifier, this audio amplifier has high pitch loudspeaker, woofer and guide pipe, of the present utility model being characterised in that: described high pitch loudspeaker is arranged in the pipe, described woofer then is set in place in a diameter another pipe greater than above-mentioned pipe diameter that high pitch loudspeaker pipe below is set, and has respectively towards the pipe that high pitch loudspeaker is set and a pilot hole of the pipe of woofer is set at the joint of two pipes.
Because audio amplifier of the present utility model has said structure, so it has following advantage:
The first, the propagation distance of low frequency air-flow increases, and has reduced the resonance frequency of audio amplifier, has increased the reverberation time of bass, produces dense, overcast low-frequency effect;
The second, the shaped double tube audio amplifier has significantly reduced the interference of standing wave owing to the structure of its tubular, has solved standing wave and has disturbed the response peak valley point problem that is caused, the fidelity of having improved sound equipment;
The 3rd, because high and low loud speaker is installed in two different planes respectively, reduced the modulation of bass to high pitch, improve the clear ability of understanding.
Now be described with reference to the accompanying drawings the utility model, wherein:
Fig. 1 is a shaped double tube audio amplifier of the present utility model.
As shown in the figure, this audio amplifier has high pitch loudspeaker 1, woofer 2 and guide pipe 3, high pitch loudspeaker 1 is arranged in the pipe, 2 of woofers are arranged in another pipe, this cylinder is positioned under the pipe that high pitch loudspeaker 1 is set ten thousand, and the diameter of woofer 2 pipes is greater than the diameter of high pitch loudspeaker 1 pipe.Joint at two pipes has a pilot hole 4, and this pilot hole 4 is respectively towards pipe that high pitch loudspeaker 1 is set and the pipe 2 that woofer is set.Propagate along the direction shown in the arrow A among the figure at this audio amplifier medium and low frequency air-flow, thereby the propagation distance of low frequency air-flow is increased.So shaped double tube audio amplifier of the present utility model has reduced the resonance frequency of audio amplifier, increased the reverberation time of bass, produce dense, overcast low-frequency effect, and solved standing wave and disturbed the response peak valley point problem that is caused, improved the fidelity of sound equipment, reduced the modulation of bass simultaneously, improved the clear ability of understanding high pitch.
In an embodiment of the present utility model, described pilot hole 4 is arranged near on the direction of loud speaker, thus the propagation distance of the air-flow that can further extend.
Claims (2)
