The utility model is used in sound boxes.

Description

The sound persuasion pipe of high tone quality horn

The utility model relates to high tone quality horn, refers in particular to a kind of loudspeaker and dredges mixer.

Have high tone quality horn audio amplifier sound persuasion pipe device now as shown in Figure 1, 2: sound persuasion pipe 1 is a straight pipe type, its inside and outside is the right angle, and the sound that accumulates in the audio amplifier 10 is interlaced, when volume when collecting sound mouth 11 and windage and produce sound press, the sound of bragging can't be heard the sound low frequency; The mouth 12 that amplifies is outer right-angle design, volume is expanded emit the direct and ambient atmosphere friction in back, make sound nonelastic short again, also do not have bass and extend, the music pliability is hard, bass effect reduces, and the noise ratio of generation reaches more than the 16Db, the effect extreme difference, noise was very big when high tone quality horn was shaken altogether, this is sound persuasion pipe 1 holding division 13, and aperture 101 diminishes on the audio amplifier 10, and can't smooth and easy control sound.Audio amplifier sound persuasion pipe device such as Fig. 3 after experiment improves, shown in 4: sound persuasion pipe 2 inlets 21 bores are constant, exporting 22 bores outwards enlarges, the block end 23 of front end strengthens, aperture 101 is strengthened with block end 23 and is controlled greatly, when high tone quality horn 102 sounding, volume, air-flow is many, outlet 22 thin volumes are bigger, inlet 21 can't only make audio amplifier 10 inner volumes dredge out in a large number the air-flow fast Absorption, and is heavy and inelastic, bass is short and do not have a last or end syllable, can't experience the tone sense that bass extends, lose the effect that subwoofer is provided with, the noise ratio in the audio amplifier 10 still is 16Db, do not reach perfect requirement, and aperture 101 controls are big, but destroyed the structure of audio amplifier 10, and row's audio fruit is still not good.

The purpose of this utility model provides all sound persuasion pipes preferably of a kind of thin audio fruit and tonequality.

The purpose of this utility model is achieved in that the sound persuasion pipe of high tone quality horn, and it is made up of sound collection suite and sound amplification suite; It is characterized in that: sound collection suite one end is provided with collection sound inlet, and collection sound inlet enlarges outward and is horn-like, and Yu Jiyin inlet outer rim is provided with guide ring, and sound collection suite end in addition is seam; Sound amplification suite one end is established connection tube, and this connection tube snaps in the seam of sound collection suite and fuses and constitute sound persuasion pipe; Sound amplification suite in addition end is provided with the mouth that amplifies, amplify mouth outward camber line extend and be connected with fastening ring, mouthful extension that amplifies of fastening ring rear side is provided with holding division, this holding division that is fastened in place, audio amplifier aperture is provided with the fixing rib.

Above-mentioned design, can be with the volume in the audio amplifier smooth and easy dredging out, reach the bass that is formed with elasticity music pliability and extend, and the effect that the high tone quality audio is broadcasted fully.

Below by drawings and Examples the utility model is described further again:

Fig. 9 is installed in schematic diagram on the audio amplifier for the utility model.

Shown in Fig. 5,6: sound persuasion pipe 1 of the present utility model is made up of sound collection suite 20 and sound amplification suite 30; It is characterized in that: sound collection suite 20 1 ends are provided with collection sound inlet 201, and collection sound inlet 201 enlarges outward and is horn-like, and Yu Jiyin 201 outer rims that enter the mouth are provided with guide ring 202, and sound collection suite 20 end in addition is seam 203; Sound amplification suite 30 1 ends are established connection tube 301, and this connection tube 301 snaps in the seam 203 of sound collection suite 20 and fuses and constitute sound persuasion pipe 40; Sound amplification suite 30 end in addition is provided with and amplifies mouthfuls 302, amplify mouthfuls 302 outward camber line extend and be connected with fastening ring 303, mouthful extension that amplifies of fastening ring 303 rear sides is provided with holding division 304, this holding division 304 that is fastened in place, audio amplifier aperture is provided with and fixes rib 305.Why establish multiple tracks and fix rib 305, it is better to hold effect for holding division 304, when sound collection suite 20 is connected with sound amplification suite 30 be integral after, constitute just as the tubaeform sound persuasion pipe 40 of twoport the usefulness of confession audio amplifier 10 thin sounds.

Shown in Fig. 7-9: holding division 304 is fastened in the aperture 101 of audio amplifier 10, and be packed in aperture 101 inner edges by fixing rib 305, high tone quality horn 102 pronunciations, empathize, volume enters sound amplification suite 30 by the collection sound inlet 201 of sound collection suite 20, is dredged out by the mouth 302 that amplifies, and is smooth and easy without hindrance, bass extends the tonequality soft elasticity bullet of music pliability and strong, and tone sense is good.Again, in the time of before volume enters collection sound inlet 201, as shown in Figure 8: stream everywhere, and when entering sound persuasion pipe 40, because the effect of guide ring 202, promptly dredge and rise to the back upper place, form a clearance space, avoid and collect the enter the mouth volume at 201 places of sound and cross, rub, and the generation noise, 303 of the fastening rings of sound amplification suite 30 front ends can guide extraneous air-flow along fastening ring 303 will amplify mouthful 302 places the volume drawing and go out, so dredge audio really and tonequality all better.
