Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1, the decomposing schematic representation of the audio amplifier of structure of shaking is delayed for the utility model band, this audio amplifier comprises for fixing the plastic parts 100 of multiple interface and accommodating the sound chamber 200 of loud speaker 500, especially, audio amplifier also comprises one for the slow flexible material connector 300 shaken, this flexible material connector 300 is sheathed on outside plastic parts 100, and the bottom of flexible material connector 300 is fixedly connected with the top in sound chamber 200.
Especially, also certain space must be left between the bottom of plastic parts 100 and the top in sound chamber 200, therefore the audio amplifier in the utility model is connected this structure by the plastic parts changed in prior art audio amplifier with the direct solid in sound chamber, a flexible material connector 300 is set in plastic parts 100 outer and be fixedly connected with the top in sound chamber 200 bottom it simultaneously, thus the acoustical vibration that audio amplifier is produced no longer by structural member solid conduction to be connected with this audio amplifier other with on the equipment of audio interface, but by leaving a fixed gap between plastic parts 100 and sound chamber 200, when audio amplifier produces acoustical vibration, acoustical vibration conducts mainly through the flexible material connector 300 be fixedly connected with sound chamber 200, namely cannot again by transmitting with part such as solid structure such as plastic parts 100 grade, and flexible material connector 300 can slow down the vibration of sound effectively, thus the acoustical vibration that greatly inhibit audio amplifier to produce is delivered on the miscellaneous equipment that is connected with this audio amplifier.
Above-mentioned plastic parts 100 adopts encapsulate technique to fix multiple interface, in the present embodiment, for three interfaces, but be not limited to this, these three interfaces are respectively interface 401, interface 402 and interface 403, an interface is wherein had to be link to loud speaker 500, two other interface can be used for fixing other equipment with audio interface be connected with this audio amplifier as microphone, mobile phone etc., therefore in the present embodiment, this audio amplifier both can independently use, also can use together with miscellaneous equipment, to use with the microphone integral formula that unites two into one, an interface must be left in these three interfaces insert for the audio output port of microphone.
In addition, this audio amplifier also comprises silica gel ring 600, plastic tube 700 and speaker net 800, wherein: silica gel ring 600, plastic tube 700 and speaker net 800 are fixedly connected sequentially bottom loud speaker 500, the bottom of loud speaker 500 is concordant with the bottom in sound chamber 200, wherein: plastic tube 700 and silica gel ring 600 can be pressed in the bottom of loud speaker 500 by screw thread or screw fastener, sound chamber 200 is sealed, and speaker net 800 then can stop extraneous dust, and the sound that loud speaker 500 is sent appears.In addition, silica gel ring 600 is also this flexible material of silica gel adopting hardness lower, other flexible material can certainly be adopted as rubber, TPU or soft plastic etc., thus make this part with solid structure part as desktop or ground etc. contact time, also can slow down the acoustical vibration that sound chamber sends.In the present embodiment, above-mentioned plastic parts 100, sound chamber 200, be set in the outer and flexible material connector 300 be fixedly connected with top, sound chamber 200 bottom it of plastic parts 100, loud speaker 500, silica gel ring 600, plastic tube 700 and speaker net 800 are combined to form audio amplifier, its integrally-built side schematic view as shown in Figure 2, composition graphs 1 and Fig. 2 known, this flexible material connector 300 is for being top seal, the cylindrical shape of bottom opening, diameter increases from top to bottom successively, and three interfaces 401, 402, 403 tops penetrating this flexible material connector 300 connect other parts, and the bottom margin of flexible material connector 300 is fixedly connected with the top in sound chamber 200, and leave a fixed gap between the top in plastic parts 100 and sound chamber 200.Fig. 3 is the stereogram of this audio amplifier, is understandable that, inside, sound chamber 200 is also provided with the parts such as control circuit, battery, bluetooth module, does not repeat them here.
Above-mentioned flexible material connector 300 can be preferably silica gel, because silica gel hardness is lower, effectively can play slow effect of shaking, be understandable that, also can select other flexible materials, as rubber or TPU, also soft plastic etc. can be selected, hardness is greatly about 80 degree or following, as long as hardness lower can effectively delaying shakes, this is not restricted.
Above-mentioned flexible material connector 300 can be preferably Openworks shape or spring-like, but can be also other shape, is not restricted at this.
The bottom of above-mentioned flexible material connector 300 can be connected to top, sound chamber 200 preferably by screw thread or screw, also directly top, sound chamber 200 can be bonded in by modes such as encapsulate, employing glue, its connected mode is not restricted at this, as long as flexible material connector can be fixedly connected on sound top of chamber.
Therefore, implement the audio amplifier that band of the present utility model delays structure of shaking, outer and be fixedly connected with the top in sound chamber 200 bottom it by a flexible material connector 300 being set in plastic parts 100, simultaneously leave a fixed gap 900 between the bottom of plastic parts 300 and the top in sound chamber 200, between the two apart from being preferably more than 4mm-5mm, avoid suffering too near and cause slow effect of shaking bad, as shown in Figure 4, delays the cutaway view of the audio amplifier of structure of shaking for the utility model band.Because flexible material connector 300 can slow down the vibration of sound and plastic parts 300 does not contact with sound chamber 200 effectively, leave space between the two thus avoid audio amplifier produce acoustical vibration be delivered to top, therefore this audio amplifier can obtain good acoustical quality as the little audio amplifier of common portable, and equipment such as microphone, the mobile phone etc. that also can have audio interface with other are combined.
Particularly, to connect microphone, the interface on plastic parts is fixed on by this audio amplifier, directly can plug microphone, when people sings loudly, because leaving a fixed gap between the bottom of plastic parts and the top in sound chamber, effectively can break audio amplifier by the flexible material connector be fixedly connected with sound top of chamber and being delivered to vibration on microphone, therefore the acoustical vibration that audio amplifier produces no longer is transmitted on microphone by solid structure part, thus effectively can suppress the generation of uttering long and high-pitched sounds.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, also can make a lot of form, these all belong within protection of the present utility model.
