Embodiment
Below, by reference to the accompanying drawings, introduce the specific embodiment of the present invention.
As Figure 1-5, air convection type phase reversal sound box, sound box 1 is cuboid body, can or simultaneously have arbitrarily in casing 1 front loudspeaker installing hole 4, casing 1 back side has two paraphase holes, described loudspeaker installing hole 4 sizes cover respectively a part for two phase-reversing tubes, as 1/3 place, left and right; The size in described hole, two phase-reversing tube two is not etc., the hole area that phase-reversing tube 2 communicates with extraneous space equals the hole area that phase-reversing tube 3 communicates with casing 1 inner space, the hole area that phase-reversing tube 2 communicates with casing 1 inner space equals the hole area that phase-reversing tube 3 communicates with extraneous space, phase-reversing tube 2 does not limit to the extraneous one end diameter D=85mm(communicating), one end diameter D=60mm(communicating with inside does not limit to); Phase-reversing tube 3 does not limit to the extraneous one end diameter D=60mm(communicating), one end diameter D=85mm(communicating with inside does not limit to); Described phase-reversing tube one end extends in casing 1 inside, and one end is fixing by paraphase hole and casing 1 in addition; The hole area that phase-reversing tube 2 communicates with extraneous space is more than the twice of the hole area that communicates with extraneous space of phase-reversing tube 3, makes the air in inner space air and extraneous space produce convection current; There is certain distance one end that described phase-reversing tube is connected with inner space and front panel inside; Audio amplifier is provided with the hole 5 of external connection end daughter board.
From above embodiment, draw, phase-reversing tube 2 and the extraneous one end hole area communicating are more than or equal to the twice of phase-reversing tube 3 and inner one end hole area that communicates, and when audio amplifier work, casing 1 inside and extraneous air can occur flow phenomenon.
Check the present invention occurs inner as follows to the mode of flow phenomenon with outside air: on the hole being communicated with extraneous space at two phase-reversing tubes first respectively, stick paper slip, while starting the work of audio amplifier low frequency, vibrating diaphragm generation porpoise, inner and the extraneous air of casing 1 produces pressure differential, forces the interior air of casing 1 to occur to flow; When vibrating diaphragm vibrates toward casing 1 internal direction, air in casing 1 is pressed inward, air will be by phase-reversing tube toward extraneous spatial flow, because phase-reversing tube is different from the size in the hole of internal communication, the pressure producing is also different, the moving air of the phase guide tube that hole area is large in the past can be than little many of hole area, so be greater than with the phase-reversing tube of extraneous space intercommunicating pore area and air can occur from inner space toward extraneous spatial flow with inner space intercommunicating pore area, so the paper being attached on phase-reversing tube 2 holes has the phenomenon of being blown outward; When vibrating diaphragm vibrates toward the extraneous direction of casing 1, the air outside casing 1 toward external pressure, air will be by phase-reversing tube toward extraneous spatial flow, because phase-reversing tube is different from the size in the hole of internal communication, the pressure producing is also different, the moving air of the conduit that hole area is large in the past can be than little many of hole area, so be greater than phase-reversing tube with inner space intercommunicating pore area with extraneous space intercommunicating pore area, can there is air and flow from extraneous space toward inner space, so the paper being attached on phase-reversing tube 3 holes has the phenomenon of being adsorbed inward; And vibrating diaphragm is in continuous porpoise, so air is in continuous convection current, so 2 continuous being blown and being adsorbed of paper, can illustrate that air convection type phase reversal sound box of the present invention is to produce cross-ventilation phenomenon, and the inner and extraneous air of casing 1 convection current constantly occurs is to reach a kind of good radiating effect; The method of check can change paper slip into smog, and smog can occur to enter from a small size hole, during the phenomenon that goes out from the large-area hole of another one.Can illustrate that the present invention can realize the inner and extraneous air of casing 1 and occur flow phenomenon, can reach good radiating effect.
