For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of overlength low frequency extends tubular type audio amplifier, and comprise frame, described frame comprises the upper shed and under shed that are communicated with up and down; One U iron enters from described under shed and is covered by this under shed, and the outer bottom of described U iron is provided with outer washer, described outer washer and U iron affixed; The inner bottom surface of described U iron is provided with a magnet, on this magnet, is provided with interior washer, the top of described interior washer and described magnet is overlapped and is wrapped up in by the bottom of a voice coil loudspeaker voice coil; One supports snare is wrapped in the top of described U iron, and outside this bracing ring, be arranged with a bullet ripple, this bullet ripple and described bracing ring affixed; One dust cap, is covered on described bracing ring and voice coil loudspeaker voice coil, and the top of described voice coil loudspeaker voice coil and described dust cap affixed; On described dust cap, be covered with vibrating diaphragm, the described upper shed of frame is covered.
In technique scheme, the outer bottom edge along described U iron is provided with depression, and the annular inner portion of described outer washer is riveted in this depression.
In technique scheme, the outer bottom indent of described U iron forms the platform of projection within it, and described magnet is arranged on this platform.
In technique scheme, the edge of described bullet ripple is set up on the step between described upper shed and under shed.
In technique scheme, described bracing ring is provided with some perforates.
In technique scheme, described dust cap is provided with central protuberance and periphery is protruding, and described voice coil loudspeaker voice coil is placed on the lateral surface of this central protuberance, and described bracing ring is placed on the protruding lateral surface in this periphery.
The invention has the beneficial effects as follows: overall structure is firm, relative to the connected mode of traditional inner part, make voice coil loudspeaker voice coil and dust cap is affixed and play ripple and the affixed improvement of bracing ring, under limitation in height, power is large, amplitude is large, can not break U iron (conventional horn voice coil loudspeaker voice coil connects bullet ripple and easily breaks U iron, and power does not quite).The upper shed of frame and under shed seal and cover by vibrating diaphragm and U iron, ensure that the sealing of audio amplifier entirety.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, 2, a kind of overlength low frequency extends tubular type audio amplifier, and comprise frame 1, described frame 1 comprises the upper shed 11 and under shed 12 that are communicated with up and down; One U iron 3 enters from described under shed 12 and is covered by this under shed 12, and the outer bottom of described U iron 3 is provided with outer washer 2, and described outer washer 2 is affixed with U iron 3; The inner bottom surface of described U iron 3 is provided with a magnet 5, and described interior washer 7 overlaps with the top of described magnet 5 and wraps up in by the bottom being provided with interior washer 7, voice coil loudspeaker voice coil 6 on this magnet 5; One bracing ring 4 cover is wrapped in the top of described U iron 3, and is arranged with a bullet ripple 8 outside this bracing ring 4, and this bullet ripple 8 is affixed with described bracing ring 4; One dust cap 9, is covered on described bracing ring 4 and voice coil loudspeaker voice coil 6, and the top of described voice coil loudspeaker voice coil 6 and described dust cap 9 affixed; On described dust cap 9, be covered with vibrating diaphragm 10, the described upper shed 11 of frame 1 is covered.Voice coil loudspeaker voice coil 6 refers to the coil by tone currents, is the important component part of dynamic speaker vibrational system, is alternatively the heart of loud speaker.The performance of voice coil loudspeaker voice coil 6 can affect the sound pressure frequency characteristic of loud speaker, sound pressure level, impedance curve, distortion, transient response, loudspeaker parameters, tonequality etc., particularly relation loud speaker bear power and life-span.Skeleton and the dust cap 9 of voice coil loudspeaker voice coil 6 are fixed.
Wherein, the outer bottom edge along described U iron 3 is provided with depression 13, and the annular inner portion of described outer washer 2 is riveted in this depression 13, and after outer washer 2 is affixed with U iron 3, the bottom surface of outer washer 2 is concordant with the bottom surface of U iron 3, and is covered by the under shed 12 of frame 1.The bottom surface of outer washer 2, the bottom surface of U iron 3 are concordant with under shed 12 bottom surface.Outer washer 2 is a ring spring pad.
Wherein, the outer bottom indent of described U iron 3 forms the platform 14 of projection within it, and described magnet 5 is arranged on this platform 14.Narrow inner space, make internal structure compacter.
Wherein, the edge of described bullet ripple 8 is set up on the step 15 between described upper shed 11 and under shed 12.The internal diameter of upper shed 11 is larger than under shed 12, and the step 15 formed between upper shed 11 and under shed 12 supports and located by bullet ripple 8.To its center drilling, be provided with the first circular arc wave band 16 and the second circular arc wave band 17 from the edge playing ripple 8, this two circular arcs wave band is used for buffering vibration and positions the center of voice coil loudspeaker voice coil 6.
Wherein, described bracing ring 4 is ring-shaped, and the limit of bracing ring 4 is provided with some perforates, and this perforate is along the circumference of bracing ring 4.
