Description
Technical field
The present invention relates to one kind to orient pronunciation device.
Background technology
Sound is the sound wave produced by object vibration.In our daily lifes, sound plays indispensable effect:Language
People can easily link up for speech, and music can releive the mood of people.But sound is influenced due to big with range of propagation
The characteristics of scope is wide, also causes number voice to influence surrounding population while incoming target receiver, such as outdoor wide
Accompaniment song on field is easy for influencing the rest of neighbouring resident.
The content of the invention
It is an object of the invention to provide one kind to orient pronunciation device, to constrain the direction of propagation that the device makes a sound.
Orientation pronunciation device of the present invention, including the babinet of some same unit lattice is divided into, in each unit
Pronunciation device assembly is fixedly installed in lattice, the pronunciation device assembly includes sonic guide inner tube and coaxial and is sleeved on sonic guide
Sonic guide outer tube outside inner tube and the pronunciation component being arranged in sonic guide inner tube, the sonic guide inner tube and sound wave
Gap is left between guiding outer tube, the rear end of sonic guide outer tube is blocked by the rear cover of an arc, pipe in the sonic guide
There is internal thread pipeline section, the pronunciation component is threaded in the internal thread pipeline section by mounting bracket, and makes the pronunciation
Element is arranged along sonic guide inner tube axis, and the front end mouth of pipe inner circumferential annular of the sonic guide inner tube is provided with acoustical cotton,
The inner surface covered in the rear is equipped with deadening felt.
Preferably, the pronunciation component includes multiturn coil, hollow magnet and forward and backward vibrating diaphragm, the multiturn coil winding
On sonic guide outer tube, the hollow magnet by front end thin hollow magnet part and rear end thick hollow magnet part structure
Into the inner ring of the preceding vibrating diaphragm and rear vibrating diaphragm is set on thin hollow magnet part and thick hollow magnet part, forward and backward to shake
The outer ring of film is connected with the mounting bracket.
Preferably, it is filled with sound-absorbing foam in the pronunciation device assembly and unit compartment.
Preferably, supporting support is arranged outside the sonic guide inner tube, the sonic guide outer tube inner peripheral surface support is solid
It is scheduled in the supporting support.
Preferably, two rotation slots are arranged with the rear end end face of the mounting bracket.
Sound is constrained by device of the present invention so that the sound that the present apparatus produces can be concentrated to front
Propagate, so as to reduce to extraneous interference.
Brief description of the drawings
Fig. 1 is the front view of the present invention;
Fig. 2 is the sectional view of the cell;
Fig. 3 is the rearview of the mounting bracket.
Embodiment
The present invention is further elaborated with reference to the accompanying drawings and examples, and following embodiments are only used for explaining this
Invention, is not intended to limit the scope of the present invention..
Orientation pronunciation device as shown in Figure 1, including the babinet of some same unit lattice 1 is divided into, in the present embodiment
Cell 1 is in 2x3 matrix arrangements.
Referring to Fig. 2, pronunciation device assembly is fixedly installed in each cell 1, the pronunciation device assembly includes sound
Waveguide is to inner tube 2 and the coaxial sonic guide outer tube 3 being sleeved on outside sonic guide inner tube and is arranged on sonic guide inner tube
In pronunciation component.
Supporting support 13 is arranged outside the sonic guide inner tube, the sonic guide outer tube inner peripheral surface is supported and fixed on this
In supporting support 13 so that gap is left between the sonic guide inner tube 2 and the outside pipe 3 of acoustic waveguide, after sonic guide outer tube
End is blocked by the rear cover 4 of an arc.The front end mouth of pipe inner circumferential annular of the sonic guide inner tube is provided with acoustical cotton 5,
The inner surface of the rear cover is covered with one layer of deadening felt 6.
The sonic guide inner tube has internal thread pipeline section 201, and the pronunciation component is threaded in by mounting bracket 7
In the internal thread pipeline section, and the pronunciation component is set to be arranged along sonic guide inner tube axis.Referring to Fig. 3, the mounting bracket
For a cylinder type stent, periphery is equipped with external screw thread, and two rotation slots are arranged with the rear end end face of the mounting bracket 7
701.For alternative sounds, the mounting bracket 7 is driven to rotate by described two rotation slots using instrument, so as to adjust peace
The distance between stent and rear cover 4 is filled, to reach optimal sound effect.
The pronunciation component can use common a variety of electric sounders, and the pronunciation component of the present embodiment includes multiturn
Coil 8, hollow magnet and forward and backward vibrating diaphragm, the multiturn coil are wrapped on sonic guide outer tube 3, and the hollow magnet is by preceding
The thick hollow magnet part 10 of thin the hollow magnet part 9 and rear end at end is formed, the inner ring of the preceding vibrating diaphragm 11 and rear vibrating diaphragm 12
It is set on thin hollow magnet part 9 and thick hollow magnet part 10, the outer ring of forward and backward vibrating diaphragm and the mounting bracket 7
Connection, the material of the forward and backward vibrating diaphragm is different, can produce the wider sound of frequency range.
To make the mouth of pipe positive outflow of the sound by sonic guide inner and outer pipe as far as possible, the diffusion in other directions is prevented, in institute
State pronunciation device assembly and unit compartment is filled with sound-absorbing foam 14.
When in use, multiturn coil is powered causes the hollow magnet vibration to above-mentioned orientation pronunciation device, so that before driving,
Diaphragm oscillations sounding afterwards.Arrow represents Acoustic Wave Propagation direction in Fig. 2, and which part sound wave is propagated forward along sonic guide inner tube,
The sound that will deviate from propagating in front through acoustical cotton at the mouth of pipe eliminates, and makes sound through the forward-propagating forward of sonic guide inner tube.Hair
Tone part produce acoustic wave segment can back-propagation, after interior surface deadening felt reflection move forward into sonic guide,
The annular gap formed between outer tube, blazes abroad forward through the gap.
