Abstract
The utility model discloses a horn type loudspeaker. The horn type loudspeaker comprises a sound production portion and an air chamber. An air chamber conduit is arranged on the air chamber, a sealing cover is arranged outside the sound production portion and the air chamber, a sound dividing cylinder whose one end is closed is arranged in the air conduit, a reflection cylinder is arranged on the sound dividing cylinder, a gap is formed between the lower end of the reflection cylinder and the end face of the sealing cover; a sound dividing tube is formed between the air conduit and the sound dividing cylinder, and a sound guide tube is formed between the reflection cylinder and the air chamber conduit, wherein the sound dividing tube is communicated with the sound guide tube. According to the horn type loudspeaker of the utility model, after the sound which is produced by the sound production portion is sent out through the sound dividing tube, the sound is reflected by the reflection cylinder in the sound guide tube and then sent out through the gap between the reflection cylinder and the sealing cover, so the loud level of the sound can be improved, and at the same time, the loudspeaker has advantages of simple structure, easy debugging and low debugging worker requirements.
Description
Technical field
The utility model relates to a kind of horn loudspeaker, belongs to loud speaker manufacturing technology field.
Background technology
Horn loudspeaker, due to advantages such as its power are large, efficiency is high, propagation distance is far away, is widely used in meeting-place, field, wide open country really and the occasions such as warning and long-distance communications.Existing horn loudspeaker because simple in structure, debugging easily, less demanding and be widely used to the commissioning staff, but that the defect of this loud speaker is sound is loud and clear not.
Summary of the invention
For above-mentioned defect, the utility model provides a kind of horn loudspeaker, when loud and clear sound is provided, still have simple in structure, debugging easily, to the less demanding advantage of commissioning staff.
To achieve these goals, the technical solution of the utility model is: a kind of horn loudspeaker, comprise pronunciation section, air chamber, the air chamber conduit is set on described air chamber, described pronunciation section and air chamber arrange seal closure outward, the partial cylinder of one end sealing is set in described air conduit, on described partial cylinder, reflecting drum is set, between the lower end of reflecting drum and the end face of seal closure, form gap; Form the partial pipe between described air conduit and partial cylinder, described reflecting drum and air chamber conduit form sound guide tube, and described partial pipe is connected with sound guide tube.
Further, described air conduit is up big and down small horn-like, and described partial cylinder and reflecting drum are up-small and down-big horn-like.
Horn loudspeaker of the present utility model, after pronunciation section sound is spread out of by the partial pipe, at sound guide tube, by the reflecting drum reflection, by the gap between reflecting drum and seal closure, flowed out, thereby improve the loud and clear degree of sound, simultaneously this loud speaker have simple in structure, debugging easily, to the less demanding advantage of commissioning staff.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.
As shown in Figure 1, horn loudspeaker of the present utility model, comprise pronunciation section 1, air chamber 2, on described air chamber 2, air chamber conduit 4 is set, the outer seal closure 3 that arranges of described pronunciation section 1 and air chamber 2, the interior partial cylinder 5 that an end sealing is set of described air conduit 4, on described partial cylinder 5, reflecting drum 6 is set, form gap between the end face of the lower end of reflecting drum 6 and seal closure 3, form partial pipe 7 between described air conduit 4 and partial cylinder 5, described reflecting drum 6 forms sound guide tube 8 with air chamber conduit 4, and described partial pipe 7 is connected with sound guide tube 8.
Described air conduit 4 is up big and down small horn-like, and described partial cylinder 5 and reflecting drum 6 are up-small and down-big horn-like.
