Preferably, described sympathetic response sheet and the audio amplifier body structure that is formed in one, described sympathetic response sheet is thicker than plastic film.
Described pcb board comprises USB sound card circuit, and this USB sound card circuit comprises digital IC element and USB sound card again.Notebook computers etc. have the electronic media device of audio frequency output by the usb signal line the utility model to be powered and play outer sound.
The utility model integral body is elongated strip, can be cylindric or shape such as prism-shaped.Described audio amplifier body is a lath-shaped, and the set described loudspeaker in its both sides are strip, and the voice coil loudspeaker voice coil of these loudspeaker is designed to strip, and the permanent magnet of cooperation also is strip accordingly.In addition, the sound basin of described loudspeaker is a tabular sound basin.
Described support two ends are installed with an end cap respectively, to seal described shell, the structural design and end cap and described support are formed in one.
Compare with present similar audio amplifier on the market, the utlity model has following beneficial effect:
1, adopts the strip loudspeaker, make its compact conformation.Simultaneously, be provided with the sympathetic response sheet, improve tonequality in the centre of two loudspeaker.And, adopted soft plastic sympathetic response sheet through discovering, and having than the fuller acoustical quality of conventional metals system sympathetic response sheet, sense of hearing is strong and powerful, and superpower innervation, bass strengthen.
2, sympathetic response sheet described in the utility model and audio amplifier body are the integral molding structure, also need the technology that metal sympathetic response sheet pastes on the plastic film is compared with tradition, and it is simple obviously to have manufacturing process, advantage with low cost.
3, described loudspeaker adopt tabular sound basin, and straight line sound wave takes place for it, even the sound of hearing at far place is also very clear, thereby has further improved the sound playing effect.
4, the utility model support is compared with traditional separating stent-graft, and support and the end cap that is used for closure are made one, has both saved manufacturing process, has reduced production cost again.

Fig. 4 is the structural representation of the utility model the foregoing description medium-height trestle.
The realization of the utility model purpose, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Further describe the technical solution of the utility model and design feature below in conjunction with a specific embodiment and accompanying drawing, so as clearer, understand technical spirit of the present utility model intuitively.
Referring to shown in Figure 1, the utility model is connected with media devices such as notebook computers by usb signal line 7 and plays sound, comprise shell 1, support 6, pcb board 5 and audio amplifier body 2, support 6 sets up audio amplifier body 2 and is fixed in the shell 1, and pcb board 5 is fixed on the audio amplifier body 2.The utility model integral body is cylindric, is shaped on a groove 11 longitudinally on the face of cylinder, and usb signal line 7 can be set and be accommodated in this groove 11.
Figure 2 shows that the structural representation of present embodiment audio amplifier body 2, as can be seen from the figure, described audio amplifier body 2 is made by rigid plastics for strip and its.Be equipped with to the bilateral symmetry of described audio amplifier body two loudspeaker 3, and in the middle of two described loudspeaker 3, be provided with the bass resonance region.Described audio amplifier body 2 is separated into three parts by four supporting brackets 8, and the left and right sides is loudspeaker 3, and the centre is the bass resonance region, and described pcb board 5 is arranged at bass resonance region top and fixing by the supporting bracket 8 of both sides.
Described bass resonance region comprises a sympathetic response sheet 4, and described sympathetic response sheet 4 is made for soft plastic, and is connected with audio amplifier body 2 and is embedded in the default hole of described audio amplifier body 2 by the plastic film of softness.Specifically be, described sympathetic response sheet and audio amplifier body are the integrally casting moulding, and the sympathetic response sheet is made by commaterial with the described plastic film that is used for being connected with the audio amplifier body.Perhaps, described sympathetic response sheet, plastic film and audio amplifier body are same material, just to the sympathetic response sheet with plastic film adopts special or common process softens it.
Fig. 3 is the structure cutaway view of loudspeaker 3 in the present embodiment.Described loudspeaker 3 are strip, the Long Circle permanent magnet 32 that it correspondingly has Long Circle voice coil loudspeaker voice coil 31 and matches with it.The sound basin 33 of described loudspeaker 3 is designed to tabular, so can send the straight line sound wave, compares the wavy sound basin of existing most of loudspeaker, and it is also very clear that it can be implemented in the sound of hearing at a distance.
