Summary technical scheme, the beneficial effects of the utility model：The most sensitive audio position of human ear that loudspeaker send with
Sender aligns, and in the little quantity that can reduce sender of the situation of identical audio frequency effect, therefore can reduce external moisture or powder
Dirt and the probability of horn contact；First support covers sender, can reduce external moisture or dust and horn contact further
Probability；Before the leading flank of loudspeaker and housing, inwall forms front sound chamber, and after the trailing flank of loudspeaker and housing, inwall forms rear sound
Chamber, because loudspeaker are near first rotating shaft, i.e. inwall before housing, the volume difference ratio in therefore front sound chamber and rear sound chamber is larger,
Make the vibrating effect of loudspeaker more preferable.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of description, and in order to allow above and other purpose of the present utility model, feature
Can become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.
Brief description
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is schematic internal view of the present utility model；
Fig. 3 is sectional view of the present utility model.
Specific embodiment
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can phases
Mutually combine.Below in conjunction with the accompanying drawings this utility model is described further.
As shown in Figure 1 to Figure 3, a kind of photographic head loudspeaker sound emitting device 10, including housing 100 and bracing frame 101, bracing frame
101 include first support 104 and second support 110, and the first rotating shaft 114 that first support 104 is passed through to be provided with is rotated with housing 100
Connect, the second rotating shaft 102 that second support 110 is passed through to be provided with is rotatably connected with housing 100；It is fixed with circle in housing 100
Loudspeaker 105, loudspeaker 105 near first rotating shaft 114 and first rotating shaft 114 axis be located at loudspeaker 105 eccentric part, housing 100
It is provided around some senders 112 of first rotating shaft 114, and sender 112 and circular loudspeaker 105 justified margin.
The most sensitive audio position of human ear that loudspeaker 105 send is alignd with sender 112, little in the situation of identical audio frequency effect
The quantity of sender 112 can be reduced, therefore can reduce the probability that external moisture or dust are contacted with loudspeaker 105；Loudspeaker 105
Leading flank and housing 100 before inwall form front sound chamber, after the trailing flank of loudspeaker 105 and housing 100, inwall forms rear sound chamber, by
In loudspeaker 105 near first rotating shaft 114, i.e. inwall before housing 100, the volume difference in therefore front sound chamber and rear sound chamber compares
Greatly so that the vibrating effect of loudspeaker is more preferable.
Specifically, the aperture of sender 112 is 1.5～3.5mm.A kind of preferred scheme is that the aperture of sender 112 is
2.5mm.The area of sender 112 is the 5%～15% of loudspeaker 105 area.A kind of preferred scheme is the area of sender 112
For loudspeaker 105 area 10%.
First rotating shaft 114 and the second rotating shaft 102 are tightly connected with housing 100 respectively, and first rotating shaft 114 is led to housing 100
Cross sealing shroud 116 formation to be tightly connected.Housing 100 is spherical structure, and housing 100 includes upper half-shell and housing lower half, upper half
Housing and housing lower half are to be detachably connected, and first support 104 is the laminated structure for covering sender 112, can be further
Reduce the probability that external moisture or dust contact with loudspeaker 105, in this utility model, first support 104 and second support 110
Structure identical.
It is provided with circuit board 117, infrared lamp bead, the fixed plate of fixing infrared lamp bead and photographic head, infrared lamp in housing 100
