Description
Technical field
The utility model relates to audio amplifier equipment field, particularly a kind of integral type audio amplifier.
Background technology
Popular along with music players such as MP3, notebook computers is applicable to that the small-sized audio amplifier of this kind equipment also comes into vogue thereupon.The common volume ratio of such audio amplifier is less, and integrated level is high, all is difficult to adopt the technology of common large-scale audio amplifier to be accomplished for assembly technology and acoustical quality.At present a lot of producers mainly make this small-sized audio amplifier through two kinds of approach: the method and complicated assembly technology that reduce tonequality.These modes not only can't satisfy the demand of consumer to high tone quality, and have increased the cost of many manufacturing small-sized audio amplifier technologies, make assembling complicated, use inconvenience, are unfavorable for promoting the use of of integrated audio amplifier.
The utility model content
The utility model problem to be solved is: provide a kind of easy to assembly, use simply, the low frequency audio is the integral type audio amplifier more perfectly.
The utility model addresses the above problem the technical scheme that is adopted: a kind of integral type audio amplifier comprises the medium density fibre board (MDF) casing and is arranged on audio amplifier plastic front board on its front end face, is arranged on the back plate on its rear end face and is arranged on its inner woofer; Described back plate offers the rear end installing hole; Described audio amplifier plastic front board offers the front end installing hole and is arranged on the circular phase-reversing tube of plastics in the installing hole of said rear end and is arranged on the senior middle school's audio tweeter in the said front end installing hole, and the stainless steel circular cone support that is used to support said woofer; Be respectively equipped with the axle and the axis hole of mutual interference fit on described audio amplifier plastic plate and the medium density fibre board (MDF) casing.The aperture of described rear end installing hole is less than the aperture of front end installing hole.Described medium density fibre board (MDF) casing is cuboid.Described senior middle school audio tweeter is two, is mirror image along audio amplifier plastic front board long side direction axis and is symmetrically distributed; Distance is 1-2cm between described two senior middle school's audio tweeters.In the position of described rear end installing hole and the position of front end installing hole one of them is corresponding.Described woofer is positioned at medium density fibre board (MDF) bottom half center, and opening is outside.The whole audio amplifier of described stainless steel circular cone stent support makes medium density fibre board (MDF) casing bottom apart from supporting surface 2-4cm; Described stainless steel circular cone support and medium density fibre board (MDF) casing are for flexibly connecting.
The beneficial effect of the utility model is:
The utility model is to the characteristics of small-sized speaker products, and the tonequality and the assembly technology of audio amplifier improved.
Improving on the tonequality, casing adopts rectangle structure to avoid the generation of standing wave, and tank material adopts the medium density fiber making to make casing that stronger inhibition vibration ability arranged; The plastics phase-reversing tube adopts circular configuration, and circular girth is minimum, makes radiation damping minimum in the pipe, and resonance frequency is in and obtains among the maximum acoustic pressure; Loud speaker is arranged in sound body both sides and becomes the mirror image symmetric figure, makes high and low sound loudspeaker unit not on same axis, helps the balance diffusion of voice unit, and the acoustic image location is more accurate; The installation site of phase-reversing tube and woofer near, make sound source trapezoidal relatively more consistent like this; Woofer is installed in the bottom of casing, and opening is outside, and keeps certain distance through stainless steel circular cone support and holder, forms the ground pressure charging system, can make woofer that good bass frequency range effect is arranged, and reduce the casing overall space; The aperture that the phase-reversing tube phase-reversing tube is installed is littler than the aperture of loud speaker, has more intense sound wave like this and goes out from phase-reversing tube, makes loud speaker forwards all obtain utilization with rearward sound wave, and audio amplifier tonequality is improved.
On assembly technology, audio amplifier plastic front board and medium density fibre board (MDF) casing make assembling convenient through the axis hole interference fit; Support adopts the corrosion-resistant height of stainless steel material, has enlarged the environment that audio amplifier uses, and support can rotate, and can regulate audio amplifier and the pendulum position is installed and put angle.
As preferably, the aperture of described rear end installing hole is less than the aperture of front end installing hole.
As preferably, described medium density fibre board (MDF) casing is cuboid.
As preferably, described senior middle school audio tweeter is two, is mirror image along audio amplifier plastic front board long side direction axis and is symmetrically distributed; Distance is 1-2cm between described two senior middle school's audio tweeters.
As preferably, one of them in the position of the position of rear end installing hole and front end installing hole is corresponding.
As preferably, described woofer is positioned at medium density fibre board (MDF) bottom half center, and opening is outside.
As preferably, the whole audio amplifier of described stainless steel circular cone stent support makes medium density fibre board (MDF) casing bottom apart from supporting surface 2-4cm; Described stainless steel circular cone support and medium density fibre board (MDF) casing are for flexibly connecting.
