In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 ~ 7, it is the preferred embodiment that the utility model provides.
It should be noted that, when parts are called as " being fixed on " or " being arranged at " another parts, it can directly on another parts or may there are parts placed in the middle simultaneously.When parts are known as " being connected to " another parts, it can be directly connected to another parts or may there are parts placed in the middle simultaneously.
Also it should be noted that, the orientation term such as left and right, upper and lower in the present embodiment, is only relative concept or be reference with the normal operating condition of product each other, and should not be regarded as have restrictive.
As shown in Figures 2 to 5, the air-line system 10 on sound equipment that the present embodiment provides, it comprises the sound equipment main body 11 with sealed internal chamber 111, the soundproof wall 12 that inner chamber 111 to be separated into front sound chamber 1111 and rear sound chamber 1112 by one is provided with in inner chamber 111, soundproof wall 12 is provided with the air port 121 being communicated with front sound chamber 1111 and rear sound chamber 1112, airduct 122 and for ordering about in inner chamber 111 air-flow in front sound chamber 1111, the loudspeaker 123 of flowing in airduct 122 and rear sound chamber 1112, airduct 122 inwall forms a level and smooth diametric plane 124, level and smooth diametric plane 124 encloses formation one air channel 125, the two ends of airduct 122 form the first openend 1221 and the second openend 1222 communicated with air channel 125, first openend 1221 is connected with air port 121, second openend 1222 is unsettled.
The air-line system 10 on sound equipment that the present embodiment provides wants to compare the beneficial effect of prior art:
As shown in Figures 2 to 5, because above-mentioned air-line system 10 on sound equipment have employed the sound equipment main body 11 and soundproof wall 12 with sealed internal chamber 111, and air port 121, airduct 122 and loudspeaker 123 are set on soundproof wall 12, airduct 122 inwall forms a level and smooth diametric plane 124, level and smooth diametric plane 124 encloses formation one air channel 125, the two ends of airduct 122 form the first openend 1221 and the second openend 1222, first openend 1221 is connected with air port 121, and the second openend 1222 is unsettled.Like this, due to the effect of vibration of loudspeaker 123, and order about air-flow round flowing in front sound chamber 1111, airduct 122 and rear sound chamber 1112 in inner chamber 111, particularly, the flowing of air-flow constantly comes and goes flowing in front sound chamber 1111, air port 121, first openend 1221, air channel 125, second openend 1222 and rear sound chamber 1112.Air channel 125 is as the principal flow passage of air-flow, the noise produced in air current flow process or noise mainly come from the process that air-flow flows in air channel 125, namely the flow-disturbing that air-flow produces airduct 122 inwall is come from, collision, friction and vibrations, therefore level and smooth diametric plane 124 is formed on airduct 122 inwall, air-flow is flowed in air channel 125 more smooth and easy, be conducive to reducing air-flow to the flow-disturbing of airduct 122 inwall, collision, friction and vibrations, be conducive to reducing noise or noise, be conducive to the tonequality and the auditory effect that improve sound equipment, therefore, to compare prior art, above-mentioned air-line system 10 on sound equipment avoids to be existed step and gap due to airduct 122 and produces noise or noise, affect the problem of sound equipment tonequality.
As shown in Figure 4, because the air-flow in air channel 125 is large and fast, when air-flow flows out via air port 121 fast in a large number, it will directly collide the inwall of sound equipment main body 11, like this, can produce noise and noise, affect auditory effect, so in order to reduce air-flow noise, air port 121 hides a soft layer 126.
It should be noted that, soft layer 126 is soft, loose or has the material of micropore, preferably, the soft layer 126 in the present embodiment is sponge, and in other embodiments, soft layer 126 also can be cotton, silk cloth etc.
The present embodiment is about the preferred implementation of the concrete structure of airduct 122, and as shown in Figure 5, airduct 122 is hollow tubular, and the cross section that airduct 122 extends to the second openend 1222 by the first openend 1221 is equal.Like this, air-flow is all equal in the flow velocity of each section of airduct 122, and air-flow velocity change is little, air-flow monolithic stability, is conducive to the noise reducing airduct 122, improves the transient response of sound equipment, improve the tonequality of sound equipment.
Refinement ground, as shown in Figure 3 and Figure 5, airduct 122 has bending part 1223 and is located at the free end of bending part 1223 with bending part 1223 integrated straight sections 1224, first openend 1221, and the second openend 1222 is located at the free end of straight sections 1224.
For portable audio, in order to pursue better bass effect, airduct 122 can design long, therefore, the length of airduct 122 is greater than the front and back degree of depth of sound equipment, and in order to reduce the front and back degree of depth of sound equipment, simultaneously, take into account the left and right width reducing sound equipment, to reduce the volume of sound equipment, the bending part 1223 of airduct 122 is designed to a right-angle bending.
As shown in figure 5 and figure 7, in order to make air-flow smoothly flow to air channel 125 by the first openend 1221, then flowed out via the second openend 1222 by air channel 125, the first openend 1221 and the second openend 1222 by interior outwardly all in flaring shape.Like this, air-flow little by little will be shunk, collect, be flow in air channel 125 by the first openend 1221, and little by little flow out from the second openend 1222, make the change of air flow state more be tending towards slow, be beneficial to the flow noise reducing air-flow.
Refinement ground, as shown in figure 5 and figure 7, in order to further make air-flow smooth and easy in the end edge portion flowing of the first openend 1221 and the second openend 1222, the end edge portion medial surface of the first openend 1221 and the second openend 1222 is curved surface 1225.Like this, air-flow by mild for the curved surface 1225 in flaring shape along the first openend 1221, come together in air channel 125 to transition, and correspondingly, mild by the curved surface 1225 of the second openend 1222, flow out to transition, therefore, the noise reducing air current flow is conducive to.
In the present embodiment, about the preferred implementation of the concrete set-up mode of airduct 122 and soundproof wall 12, as shown in Figures 4 to 6, soundproof wall 12 is also provided with a fixture 127, fixture 127 and soft layer 126 are located at the relative both sides in air port 121 respectively, fixture 127 has the endoporus 1271 of fitting mutually with air port 121 shape, and endoporus 1271 periphery forms slot 1272, first openend 1221 and is inserted in slot 1272.Like this, when airduct 122 being pulled down from soundproof wall 12 or airduct 122 being loaded onto soundproof wall 12, only need the first openend 1221 of airduct 122 to extract from slot 1272 or be inserted in slot 1272 by the first openend 1221.
In other embodiments, airduct 122 by the first openend 1221 with paste, screw togather or be formed on soundproof wall 12 with the integrated mode of soundproof wall 12, the front sound chamber 1111 of sound equipment inner chamber 111 is communicated with rear sound chamber 1112, allows air-flow flow swimmingly between front sound chamber 1111, air port 121, first openend 1221, air channel 125, second openend 1222, rear sound chamber 1112.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
