Abstract
The utility model relates to a sound equipment technical field discloses an intermediate frequency loudspeaker heat abstractor, the airtight sound chamber of enclosing including box, loudspeaker subassembly, by box and loudspeaker subassembly, set up at the first through -hole of bottom half, set up the box outside and the fin of closed first through -hole and the metal conduit who is connected with the fin, the loudspeaker subassembly returns the subassembly including drum paper, voice coil loudspeaker voice coil, annular damping circle, basin frame and setting at the annular magnetism that the basin put up the right side, magnetism goes back to the subassembly center and is equipped with the second through -hole that holds metal conduit. The utility model discloses the one end disect insertion that utilizes metal conduit returns the second through -hole at subassembly center to intermediate frequency loudspeaker magnetism in, the other end links to each other with the outer fin of box, utilizes the method of metallic conductance, and with the heat of the voice coil loudspeaker voice coil airtight sound chamber of discharging, effectively lowering the temperature avoids power to compress rapidly.
Description
Technical field
The utility model belongs to stereo set technical field, is specifically related to a kind of intermediate frequency loudspeaker heat abstractor.
Background technology
At present in Specialty Hi-Fi field, particularly up-to-date large-scale Linear array loundspeaker box all adopts three frequency division to design, wherein, intermediate frequency loudspeaker are in order to provide sensitivity, closed cavity body structure must be adopted, and the volume of cavity very tiny, the effect promoting intermediate frequency sensitivity can be reached like this.But such structure can allow intermediate frequency loudspeaker be operated in inside a confined space, and the heat that loudspeaker produce cannot be got rid of, cause the temperature of intermediate frequency loudspeaker to rise, be easy to emergent power compression phenomena.Power compression is because the voice coil loudspeaker voice coil of loudspeaker unit is heated, and internal resistance is risen, and when identical input voltage, resistance rises will cause power drop.Because professional sound amplifying sound box can be operated under powerful state for a long time, this situation can be very general.
Therefore, the intermediate frequency loudspeaker heat abstractor providing a kind of and can effectively reduce temperature, avoid power compression is needed badly.
Utility model content
For above-mentioned Problems existing, the utility model provides a kind of intermediate frequency loudspeaker heat abstractor, when keeping airtight sound chamber, gets rid of the heat in it, reduces temperature, avoids power compression occurs.
The utility model for achieving the above object, takes following technical scheme to be achieved:
A kind of intermediate frequency loudspeaker heat abstractor, comprise casing, horn assembly, the airtight sound chamber surrounded by casing and horn assembly, the first through hole being opened in bottom half, be arranged on casing outer and the fin closing the first through hole and the metal catheter be connected with fin, described horn assembly comprises bulging paper, voice coil loudspeaker voice coil, annular damper circle, frame and the annular magnetic be arranged on the right side of frame and returns assembly, and described magnetic goes back to assembly center and is provided with the second through hole holding metal catheter.
Preferably, described metal catheter outer wall and the second through-hole wall are close to setting.
Preferably, described metal catheter free end and voice coil loudspeaker voice coil leave gap.
Preferably, described metal catheter sidewall offers some third through-holes.
Preferably, described magnetic returns assembly and comprises the top iron and screw, magnet and the T iron that are connected with frame bottom surface successively.
Preferably, described voice coil loudspeaker voice coil to be arranged on bottom frame and to be close to magnetic and returns assembly, and embed annular damper circle center on the left of described voice coil loudspeaker voice coil and be connected with Gu Zhi center, described annular damper circle periphery is fixedly connected with frame, and described bulging paper periphery is fixedly connected with frame left end.
Preferably, described Gu Zhi center is provided with dust cap.
Compared with prior art, the beneficial effects of the utility model are as follows: the utility model utilizes one end of metal catheter to be directly inserted in second through hole at intermediate frequency loudspeaker magnetic back assembly center, the other end is connected with the fin outside casing, utilize the method for metal conduction, rapidly the heat of voice coil loudspeaker voice coil is discharged airtight sound chamber, effectively can reduce temperature, avoid power compression.
The utility model is applied to Specialty Hi-Fi field, and time in especially large-scale Linear array loundspeaker box, fin can utilize the air-flow of other loudspeaker (as Low frequency horn) to do cooling initiatively.
