Abstract
The utility model discloses a sound box with a tubular structure, which comprises a loudspeaker and a sound induction tube, wherein the loudspeaker is arranged at the inner wall of a port at one end of the sound induction tube, an interference wave notch and a sound outlet are arranged on the sound induction tube which is in distance of 5 to 7 times of the tube diameter with the loudspeaker; or the loudspeaker can be arranged in the middle inner wall of the sound induction tube, and the interference wave notch and the sound outlet are arranged at each position which is in distance of 5 to 7 times of the tube diameter with two ends of the loudspeaker. The width of the interference wave notch on the sound induction tube is 1 to 2 millimeters, and the length thereof is one fourth to one fifth of the pipe perimeter; the width of the sound outlet is 1 to 2 millimeters, the length thereof is one fourth to one fifth of the pipe perimeter, and the number of the notches is 5 to 7. The sound outlet can be arranged in 4 to 5 rows, and 5 to 7 circular holes with the diameter of 1 to 2 millimeters are arranged in each row. The sound box with the tubular structure has good sound surrounding effect, balanced sound transmission space, small occupied space, wide application range, and well utilization value in the aspects of room sounding design and car sounding structure composition.
Description
Technical field
The utility model belongs to the audio amplifier field, relates in particular to a kind of tubular structure audio amplifier.
Background technology
At present, employed audio amplifier substantially all is a body structure in our daily life, the style dullness, relatively take bigger living space, and a limited number of acoustics of raising living device generation make the people that unbalanced sense be arranged acoustically, also be difficult to the acoustics that reaches desirable on household and placement location, the directionality around always producing sounding body with third dimension of sound is disturbed, and is difficult to reach surrounding effect real on the sound equipment.If want to reach the surrounding effect of expection, a plurality of loud speakers need be set usually just can finish.Though the application of electron controls technology has clear improvement existing audio amplifier on acoustical quality.But aspect loudspeaker box structure, produce the also also few of remarkable result.
The utility model content
The purpose of this utility model is to provide a kind of novel structure simple, the equilibrium of sound equipment communication space, the tubular structure audio amplifier that audio mixing and surrounding effect are good.
The technical solution of the utility model is: the tubular structure audio amplifier mainly comprises loud speaker and sound guide tube, and loud speaker is installed in an end inwall port of sound guide tube, communicates with sound guide tube; On the long sound guide tube of 5-7 times of pipe shaft diameter of distance loud speaker, the disturbing wave otch is set, at a distance of the long sound guide tube place of 5-6 times of pipe shaft diameter of disturbing wave otch sound mouth is being set, in 6-7 times of pipe shaft diameter strong point at a distance of sound mouth sound mouth being set, is other end outlet in 6-7 times of pipe shaft diameter strong point at a distance of sound mouth.
Loud speaker is installed in the middle part inwall of sound guide tube, communicates with sound guide tube; With each 5-7 of loud speaker two ends times of pipe shaft diameter strong point the disturbing wave otch being set, in 5-6 times of pipe shaft diameter strong point apart from this disturbing wave otch sound mouth being set, is the two ends outlets in 6-7 times of pipe shaft diameter strong point at a distance of sound mouth.
The disturbing wave kerf width is the 1-2 millimeter on the sound guide tube, and length is the 1/4-1/5 of pipe girth.
The sound mouth width is the 1-2 millimeter on the sound guide tube, and length is the 1/4-1/5 of pipe girth, and otch is 5-7.
Sound mouth is arranged as 4-5 row, the circular hole of 5-7 diameter 1-2 millimeter of every row, and sound mouth is provided with 1-3 in leading note pipe shaft uniform distances position
The utility model can reach following good result:
The tonequality surrounding effect is good, and the equilibrium of sound transmission space has multi-faceted sense, has the remarkable result of a plurality of sound sources of loud speaker, and sound source is had certain transfer, propagates the original flavor that has guaranteed tonequality in pipe, and the concussion of sound wave has certain reinforcement, and audio mixing is effective.Use to arrange that it is little to take up room on the effect, the scope of application is wide, and all there is good value acoustic structure composition aspect in room sounding design and automobile car, makes that acoustics reaches preferable states in the space.
Description of drawings
Fig. 1 is provided with structural front view for tubular structure audio amplifier loud speaker one end;
Fig. 2 is for being provided with structural front view in the middle of the tubular structure audio amplifier loud speaker.
Embodiment
Embodiment 1: as shown in Figure 1, the pronunciation mouth of loud speaker 1 is installed in an end inwall port of sound guide tube 2, on the long sound guide tube 2 of 5-7 times of pipe shaft diameter of distance loud speaker, wide 1-2 millimeter is set, the disturbing wave otch 3 of pipe shaft girth 1/4-1/5, directly locating to be provided with sound mouth 4 apart from 5-6 times of long body of caliber of this disturbing wave otch, directly locating to be provided with sound mouth 5 at the 6-7 times of long body of caliber at a distance of sound mouth 4, is other end outlet 6 in 6-7 times of caliber strong point at a distance of sound mouth 5.Sound is by propagating in the pipe, and sound wave superimposed oscillation in pipe produces good resonance effect, keeps the frequency of vibration, and disturbing wave otch 3 is that audio mixing in managing is carried out suitable interference, removes the acoustic resonance noise.Sound mouth 4 is derived sound wave at opening part, forms a sound source, along with the continuation of sound in pipe propagated, equally sound wave is derived to sound mouth 5, and the other end of pipe exports 6 at last derives sound wave.
Embodiment 2: as shown in Figure 2, loud speaker 1 pronunciation mouth is installed in the inwall place, middle part of sound guide tube 2, and loud speaker 1 pronunciation mouthful and sound guide tube 2 engage sides, and loud speaker 1 pronunciation mouthful present position communicates with sound guide tube 2.With each 5-7 times of pipe shaft diameter strong point in loud speaker 1 two ends disturbing wave otch 3 being set, in 5-6 times of pipe shaft diameter strong point apart from this disturbing wave otch 3 sound mouth 4 being set, is two ends outlet 6 in 6-7 times of body straight tube footpath strong point at a distance of sound mouth 4.Sound is by propagating in the pipe, and sound wave superimposed oscillation in pipe produces good resonance effect.
