Abstract
The utility model provides a sound orientation device. The sound orientation device comprises a sound source device fixed on a plaster suspended ceiling, wherein the sound source device comprises a master device and a speaker; a sound guide tube is arranged at each of horn mouths of the speaker respectively for playing sounds; the final sound of the sound source device is transmitted from holes of the sound guide tubes; and the adjacent sound guide tubes are fixed by fixing sheets. The utility model has the advantages and effects that as the above technical scheme is adopted, sound diffusion is greatly reduced and the volume can keep loud when the sound reaches the bottom. The sound orientation device can also be used alone and is convenient to install.
Description
Technical field
The utility model belongs to the sound play device technical field, especially relates to a kind of sound directing device.
Background technology
In the prior art; Be installed in the sound play device of the how intensive public place of eminence and people, generally above the gypsum furred ceiling, the source of sound of below is very noisy for its installation environment; The sound that makes sound play device send has remained little when arriving the below; And because sound play device up, sound dispersion is serious, the environment around can having influence on.
Summary of the invention
The problem that the utility model will solve provides a kind of sound directing device, makes the people of below can hear the sound that the sound source device sends more clearly.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of sound directing device; Comprise the sound source device that is fixed on the gypsum furred ceiling; It comprises main equipment and audio amplifier; Each horn mouth place that said audio amplifier plays sound is equipped with a sound guide tube, and the last sound of sound source device transfers out from the hole of sound guide tube, fixes through stator between the adjacent sound guide tube.
Further, the below of said sound guide tube and gypsum furred ceiling maintain an equal level.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, sound dispersion reduces greatly, and the volume of sound when arriving the below is very big; This sound directing device also can use separately and simple installation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
1, audio amplifier 2, sound guide tube 3, stator
Embodiment
It is as shown in Figure 1,
A kind of sound directing device of the utility model; Comprise the sound source device that is fixed on the gypsum furred ceiling; It comprises main equipment and audio amplifier 1; Each horn mouth place of said audio amplifier 1 is equipped with a sound guide tube 2, and the below of said sound guide tube 2 and gypsum furred ceiling maintain an equal level, and is fixing through stator 3 between the adjacent sound guide tube 2.
The course of work of this instance:
