Abstract
The utility model discloses an acoustic public-address cavity, comprising a public-address cavity. Two sides of the top of the public-address cavity is provided with a first sound hole and a second sound hole of the public-address cavity; the middle bottom is provided with a buzzer; a sound guide pipe is arranged between the top of the buzzer and the public-address cavity; and two ends of the buzzer are provided with a first sound chamber and a second sound chamber. The utility model has advantages of simple structure, sound concentration and high sound pressure.
Description
Technical field
The utility model relates to a kind of public address set, is specifically related to a kind of acoustics cavity that amplifies.
Background technology
At present in the use of hummer, general user is when its designed enclosures, the shell of the sound hole position of corresponding hummer opened directly open several circular holes or square hole and be used for sound radiation and come out, but good sound dispersion function is not substantially all played in such design, that have even can influence dispersing of sound, cause the output of hummer sound to reduce.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of acoustics cavity that amplifies is provided, and the utility model is simple in structure, in the sound set, and the sound press height.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of acoustics cavity that amplifies, comprise the cavity that amplifies, the described both sides, cavity top that amplify are provided with the amplify sound hole in chamber and No. two sound holes in chamber that amplify, central bottom is provided with hummer, described hummer top and amplify and be provided with sound guide tube between the cavity, and two ends are provided with amplify sound chamber, chamber and No. two sound chambeies, chamber that amplify.
Further, the described sound hole in chamber that amplifies, amplify sound chamber, chamber and sound guide tube communicate.
Further, described No. two sound holes in chamber that amplify, amplify No. two sound chambeies, chamber and sound guide tube communicate.
Further, described hummer top is provided with the hummer sender, and described hummer sender communicates with sound guide tube.
The beneficial effects of the utility model are:
Compared with prior art, the utility model technological merit mainly is under equal power consumption, effectively utilizes the peripheral structure space, makes small hummer can send bigger sound press.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is vertical view of the present utility model;
Fig. 2 is elevational sectional view of the present utility model.
Number in the figure explanation: 1, the sound hole in chamber that amplifies, 2, the sound chamber, chamber that amplifies, 3, hummer, 4, the hummer sender, 5, sound guide tube, 6, No. two sound chambeies, chamber that amplify, 7, No. two sound holes in chamber that amplify, 8, cavity amplifies.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Figure 1, a kind of acoustics cavity that amplifies, comprise the cavity 8 that amplifies, the described both sides, cavity 8 top that amplify are provided with amplify sound hole in chamber 1 and No. two sound holes 7 in chamber that amplify, central bottom is provided with hummer 3, described hummer 3 tops and amplify and be provided with sound guide tube 5 between the cavity 8, and two ends are provided with amplify sound chamber, chamber 2 and No. two sound chambeies 6, chamber that amplify.
Further, the described sound hole 1 in chamber that amplifies, amplify sound chamber 2, chamber and sound guide tube 5 communicate.
Further, described No. two sound holes 7 in chamber that amplify, amplify No. two sound chambeies 6, chamber and sound guide tube 5 communicate.
Further, described hummer 3 tops are provided with hummer sender 4, and described hummer sender 4 communicates with sound guide tube 5.
The principle of work of present embodiment is as follows:
Sound is produced by hummer 3, send from sender 4, enter amplify sound chamber, chamber 2 and No. two sound chambeies 6, chamber that amplify respectively via sound guide tube 5, produce the subresonance stack through the sound chamber, chamber 2 that amplifies synchronously with No. two sound chambeies, chamber 6 that amplify, send with No. two sound holes 7 in chamber that amplify from the sound hole in chamber 1 that amplifies at last.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
