Description
Technical field
The utility model relates to a kind of audio amplifier, particularly a kind of active audio amplifier.
Background technology
As everyone knows, active audio amplifier is when work, its power amplifier can produce a large amount of heats, and power is big more, caloric value is also just big more, for the difficult problem that solves heat radiation to avoid the generation of power amplifier because of the phenomenons such as deficiency burns out of dispelling the heat, someone adopts device radiation device thereon, and power amplifier is placed on outside the sound box bodies, because its heating and radiating element are direct and the external world carries out heat exchange, radiating effect is better, but its weak point is: one, external power amplifier impairs the good looking appearance of audio amplifier, itself and the extraneous area that contacts have been reduced and will hide radiating element, reduced radiating effect,, often added electronic radiation again and fan the amount of flow that improves air in order to solve its conflicting problem, reach the purpose of quick heat radiating, playing the acoustical quality that influences audio amplifier often because of the broken wind hum that heat emission fan produced; Two, being installed in outer radiator is tusk, and periphery is sharper keen, uses dangerous; Three, radiator relies on free convection and radiation, radiating efficiency not high.The patent No. is the rapid heat radiation device that the Chinese patent of ZL97209009 discloses a kind of active audio amplifier for this reason, it adopts and be axially arranged with some heat radiation tooth bars on the internal chamber wall of phase-reversing tube, thereby phase-reversing tube and radiator are installed in the casing with uniting two into one, both improved the aesthetic property of its profile, improved simultaneously the speed of its heat radiation again, reduced production cost, but its shortcoming is because the paraphase radiator is holistic tubular body, and because radiation tooth sets within it on the sidewall, cross-ventilated space and speed had both been reduced, thereby influence its radiating effect, effect owing to radiation tooth produces howling easily in phase-reversing tube when carrying out gaseous exchange simultaneously, influence its acoustics, and radiation tooth is big at the difficulty of processing of inside pipe wall, low precision, rough surface is attractive in appearance and influence its security performance.
Summary of the invention
The purpose of this utility model is to address the above problem, but a kind of quick heat radiating is provided, and simple in structure, handling ease, production cost are low, the active audio amplifier of good looking appearance.Further purpose of the present utility model on this basis provides a kind of active audio amplifier that can regulate its low frequency reverberation effect as required.
The technical solution of the utility model is achieved in that
Active audio amplifier described in the utility model, comprise sound box bodies and be installed on this sound box bodies interior loud speaker, power amplifier, phase-reversing tube, be characterized in that described phase-reversing tube is for being paraphase radiator semicircle shape and that arc device that its outside respectively is provided with a wing plate forms by two, and be respectively equipped with some heat radiation tooth bars on the outer wall of described each arc and the lateral wall of each wing plate, each electronic devices and components in the above-mentioned power amplifier are installed on respectively on above-mentioned each wing plate.
Can regulate its low frequency reverberation effect according to different needs for making the utility model, guarantee the acoustical quality of its broadcast, reaching further purpose of the present utility model, the posterior means of above-mentioned phase-reversing tube have that extend internally an and adjustable in length in order to regulate the frequency response adjustable pipe of low frequency reverberation effect.
For further making it simple in structure, easy for installation, the both ends of each arc of above-mentioned phase-reversing tube be provided with respectively arc-shaped slot that a band closes up and can with the card article of the mutual snapping of this arc-shaped slot, the card article of two arcs by its end connects as one with corresponding clamping of arc-shaped slot, and above-mentioned each wing plate lays respectively at the outer wall medium position of described each arc and be axially parallel staggered.
The utility model is owing to adopt by two and be semicircle shape and phase-reversing tube that arc device that its outside respectively is provided with a wing plate forms and be respectively equipped with the structure of some heat radiation tooth bars on the lateral wall of the outer wall of phase-reversing tube and each wing plate, both effectively phase-reversing tube and heat abstractor organically were combined as a whole, reduced simultaneously difficulty of processing again, reduced production cost, and be arranged at that the outer heat radiation tooth bar of phase-reversing tube contact with outside air directly that the heat that makes the heater element generation when work that is installed on the power amplifier on the wing plate is brought into airspace rapidly and convection current discharge in the phase-reversing tube, radiating rate and efficient are improved greatly.And, can effectively avoid producing howling because phase-reversing tube is a smooth inner wall, improve its result of broadcast.Because the utility model also adopts the structure at the posterior means one frequency response adjustable pipe that extend internally and its length of scalable of phase-reversing tube, make it can regulate its low frequency as required and easily simultaneously, further guarantee the acoustical quality of its broadcast.
Below in conjunction with accompanying drawing the utility model is further described.
