A speaker horn with a heat dissipation function according to this embodiment, a left inclined surface boss 324 is provided at the end of the left inclined reversing groove 323; a right inclined surface boss 334 is provided at the end of the right inclined reversing groove 333; the left inclined surface boss 324 is disposed opposite to the right vertical reversing groove 332; the right inclined surface boss 334 is disposed opposite to the left vertical reversing groove 322; magnetic coatings are provided on the groove walls of the first driving groove 321 and the second driving groove 331; the driving shaft 61 is a metal part; non-magnetic layers are provided on the left inclined surface boss 324 and the right inclined surface boss 334.

[0053] Specifically, for the speaker horn with a heat dissipation function according to this embodiment, the length of the driving shaft 61 is longer than the length of the telescopic hole, but less than the width of the channel 31, that is, the driving shaft 61 cannot be in contact with both the first driving groove 321 and the second driving groove 331 at the same time.

[0054] When the initial state is: one end of the drive shaft 61 is arranged at the bottom of the left vertical reversing groove 322, and the other end of the drive shaft 61 is separated from the second drive groove 331; during the operation of the speaker assembly, when the vibrating voice coil 21 rises, it drives the pressure plate 23 to rise through the resonance frame 22, and under the action of the return spring 64, the drive block 6 always abuts against the bottom of the pressure plate 23, so that the drive block 6 rises, causing the drive shaft 61 to move along the left vertical reversing groove 322 to the top of the left inclined groove 327; then when the vibrating voice coil 21 descends, it drives the pressure plate 23 to descend through the resonance frame 22, and the pressure plate 23 pushes the drive block 6 to descend. Due to the arrangement of the strip groove 63, the descent of the drive block 6 does not affect the double pump 5 until the drive shaft 61 in the drive block 6 descends to the bottom of the strip groove 63, at which time the drive block 6 can no longer descend, so that one end of the drive shaft 61 starts to move along the inclined surface of the left inclined groove 327. Then when one end of the drive shaft 61 moves to the middle of the left vertical groove 326, the vibrating voice coil 21 rises again, driving one end of the drive shaft 61 to move to the middle of the left vertical groove 326 again; one end of the drive shaft 61 can move forward along the left lifting groove 325 according to the lifting and lowering of the vibrating voice coil 21, so as to drive the double pump 5 to move forward through the connecting rod 62. And since the drive shaft 61 is a metal part and the groove wall of the first drive groove 321 is provided with a magnetic coating, the drive shaft 61 will not fall in the first drive groove 321;

[0055] Until one end of the drive shaft 61 moves to the left inclined surface boss 324 at the end of the left inclined reversing groove 323, the inclined surface on the left inclined surface boss 324 continuously pushes the drive shaft 61 to retract into the telescopic hole, and after extending out from the other end of the telescopic hole, it is inserted into the right vertical reversing groove 332 of the second drive groove 331. Since the left inclined surface boss 324 is provided with a magnetic insulation layer and the right vertical reversing groove 332 of the second drive groove 331 is provided with a magnetic coating, when the left inclined surface boss 324 pushes the drive shaft 61 into the right vertical reversing groove 332, one end of the drive shaft 61 is separated from the first drive groove 321, and the other end of the drive shaft 61 is adsorbed to the second drive groove 331. Since the first drive groove 321 and the second drive groove 331 are rotationally symmetric structures, when the vibrating voice coil 21 moves up and down, the other end of the drive shaft 61 can move in the reverse direction along the right lifting groove 335 according to the lifting and lowering of the vibrating voice coil 21, so as to drive the double pump 5 to move in the reverse direction through the connecting rod 62.

[0056] When the other end of the drive shaft 61 moves to the right inclined reversing groove 333, the double pump 5 moves forward again, causing the drive pump to continuously perform reciprocating translation.

[0057] A speaker horn with a heat dissipation function according to this embodiment, the bidirectional pump 5 includes a pump body 7; a cylindrical cavity 71 is provided in the pump body 7; a cylindrical valve core 72 is rotatably provided in the cylindrical cavity 71; the cylindrical valve core 72 is eccentrically arranged with the cylindrical cavity 71; the side wall of the cylindrical valve core 72 abuts against the inner wall of one side of the cylindrical cavity 71; first valve pieces 73 and second valve pieces 74 are respectively arranged at both ends of the cylindrical valve core 72 in a telescopic and movable manner; the first valve pieces 73 and the second valve pieces 74 are respectively arranged along the diameter direction of the cylindrical valve core 72; a first spring 75 is arranged between the first valve piece 73 and the cylindrical valve core 72; a second spring 76 is arranged between the second valve piece 74 and the cylindrical valve core 72; the first valve piece 73 abuts against the inner wall of the cylindrical cavity 71 through the first spring 75; the second valve piece 74 abuts against the inner wall of the cylindrical cavity 71 through the second spring 76; the first interface 51 and the second interface 52 are respectively communicated with both ends of the cylindrical cavity 71. A speaker horn with a heat dissipation function according to this embodiment, the switching mechanism includes a driving frame 8 movably arranged at the bottom of the box body 1; first friction surfaces 81 and second friction surfaces 82 are respectively arranged on both sides of the driving frame 8; a friction wheel 77 is rotatably arranged at the bottom of the pump body 7; the friction wheel 77 is coaxially driven with the cylindrical valve core 72; an impeller 78 is rotatably arranged on the top of the friction wheel 77 in the pump body 7; the impeller 78 is coaxially driven with the friction wheel 77; the friction wheel 77 is used to abut against the first friction surface 81 or the second friction surface 82; the box body 1 is provided with an air inlet 11 and an air outlet 12; the second water tank 43 is provided with a plurality of heat dissipation fins 46. A speaker horn with a heat dissipation function according to this embodiment, the pump body 7 is provided with a steering block 9; first steering inclined surfaces 91 and second steering inclined surfaces 92 are respectively arranged on both sides of the steering block 9; a third steering inclined surface 83 matched with the first steering inclined surface 91 is arranged at one end of the driving frame 8; a fourth steering inclined surface 84 matched with the second steering inclined surface 92 is arranged at the other end of the driving frame 8; a first magnet 85 is arranged on the outer wall of one side of the driving frame 8; a second magnet 86 is arranged on the outer wall of the other side of the driving frame 8; a third magnet 13 for adsorbing with the first magnet 85 and a fourth magnet 14 for adsorbing with the second magnet 86 are arranged at the bottom of the box body 1.

[0058] Specifically, for the speaker horn with a heat dissipation function in this embodiment, the diameter of the friction wheel 77 is smaller than the width of the driving frame 8, which means that the friction wheel 77 can only contact the first friction surface 81 or the second friction surface 82; the first friction surface 81 and the second friction surface 82 are uneven surfaces; when the double-direction pump 5 moves forward, the driving frame 8 is attracted by the third magnet 13 of the box body 1 through the first magnet 85, so as to prevent the driving frame 8 from shaking; when the double-direction pump 5 moves forward, the friction wheel 77 abuts against the first friction surface 81, so that the friction wheel 77 rotates clockwise to drive the cylindrical valve core 72 to rotate clockwise, enabling the liquid to flow forward between the first water tank 41 and the second water tank 43.

[0059] Until the double-direction pump 5 moves to one end of the driving frame 8, due to the abutment of the first inclined surface of the steering block 9 and the third inclined surface of the driving frame 8, the driving frame 8 moves, causing the first magnet 85 to separate from the third magnet 13 and the second magnet 86 to be attracted to the fourth magnet 14. At this time, the friction wheel 77 abuts against the second friction surface 82; and at this time, the double-direction pump 5 starts to move backward, and the friction wheel 77 abuts against the second friction surface 82, so that the friction wheel 77 rotates counterclockwise to drive the cylindrical valve core 72 to rotate counterclockwise, enabling the liquid to flow backward between the first water tank 41 and the second water tank 43.

[0060] Through the above settings, during the operation of the vibrating voice coil 21, the double-direction pump 5 is driven to continuously move forward and backward. When the double-direction pump moves forward, the cylindrical valve core 72 rotates clockwise, enabling the liquid to flow forward between the first water tank 41 and the second water tank 43. When the double-direction pump moves backward, the cylindrical valve core 72 rotates counterclockwise, enabling the liquid to flow reversely between the first water tank 41 and the second water tank 43; thereby accelerating the flow of the liquid between the first water tank 41 and the second water tank 43, accelerating the conduction of the liquid heat. And during the movement of the double-direction pump, the impeller 78 rotates simultaneously. Under the action of the air inlet 11 and the air outlet 12, an air flow is generated to dissipate heat from the second water tank 43. At the same time, the heat dissipation fins 46 of the second water tank 43 can accelerate the heat dissipation of the second water tank 43; thus effectively enhancing the overall heat dissipation capacity of the speaker.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
