Abstract
The utility model provides an overhead compound air horn, comprising two air horns, of which one is a high air horn with frequency of 200+/-20 Hz, and the other one is a low air horn with the frequency of 175+/-20 Hz. An althorn and a bass horn are used in match, so the sound is melodious, soft and vigorous, with low noise.
Description
Technical field
The utility model relates to heavily, the overhead loudspeaker of Medium Truck.
Background technology
The double-tone air horn of producing is left and right each one at present, its profile unanimity.Length dimension is 625max., the frequency unanimity, the tone that sends is also consistent, and sound is loud and sonorous strong.Its shortcoming be too ear-piercing, noise is big.
Summary of the invention
For make heavily, the overhead loudspeaker of Medium Truck get gentle in voice not ear-piercingly, the utility model proposes the high and low double-tone air horn of overhead.
For this reason, the technical solution of the utility model is: the high and low double-tone air horn of overhead, form by two air horns, and it is characterized in that: one is the high pitch air horn, and frequency is 220 ± 20Hz; Another is the bass air horn, and frequency is 175 ± 20Hz.
Beneficial effect: because loudspeaker are high pitchs, loudspeaker are basses, and pairing is used, and the sound that sends is melodious, soft and simple and honest, and noise is little.
Description of drawings
Fig. 1 is the structural drawing of overhead air horn.
Fig. 2 is the outside drawing of overhead bass air horn.
Fig. 3 is the outside drawing of overhead high pitch air horn.
Embodiment
The structure of bass air horn and high pitch air horn is consistent, as shown in Figure 1, heavily, the structure of the overhead air horn of Medium Truck is: comprise hydraucone 1, cone 5, fore-stock 2, horn base 6, spring 10 is contained in horn hood 9 draw-in grooves, diaphragm 11 is contained in the horn base 6, horn hood 9 is connected horn base 6 afterbodys by screw 8, and draft tube joint 13 is connected at the bottom of the horn base 6 ones, and horn base 6 bottoms are bonded with sealing gasket 12; The bottom of fore-stock 2 is bonded with sealing gasket 14, is with rubber sheath 4 in the mounting hole of fore-stock 2, is socketed in then on the cone 5; Cone and hydraucone are one by rivet 3 riveted joints, and the afterbody of cone 5 is connected on the horn base 6.Be provided with O-ring seal 7 between the afterbody of cone 5 and the horn base
The difference of bass air horn and high pitch air horn is the length and the sound frequency of loudspeaker.
As shown in Figure 2, the frequency of bass air horn is 175 ± 20Hz.The bass air horn length L 1 be the 600-625 millimeter.L1 is meant the length of hydraucone to the horn base afterbody.
As shown in Figure 3, the frequency of high pitch air horn is 220 ± 20Hz.The high pitch air horn length L 2 be the 425-450 millimeter, L2 is meant the length of hydraucone to the horn base afterbody.
Claims (2)
