Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
It please refers to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, of the invention is a kind of suitable under remote high-noise environment
Sound collector, including the staggered reflecting surface 6 on pedestal 1 of pedestal 1 and at least two groups, the pedestal 1 is equipped with and reflection
The one-to-one pickup cartridge 2 in face 6, the 2 free end end of pickup cartridge are equipped with the first high directional microphone 3, the pickup
The end that pipe 2 is connect with pedestal 1 is equipped with the second high directional microphone 4 opposite with reflecting surface 6, the described first high direction Mike
At least one omni-directional microphone 5 is placed between wind 3 and the second high directional microphone 4, the reflecting surface 6 refers to sound
Reflection focuses to the reflecting surface 6 of trumpet type or parabolic type at the second high directional microphone 4, can assemble more sound-source signal and
Accurate feedback keeps reception more preferable to the second high directional microphone 4, and the high directional microphone 3 of described first and the second height refer to
To at least one omni-directional microphone 5 is placed between microphone 4, it is located at the first high directional microphone 3 and the second high direction wheat
Gram wind 4, which is nearby arranged, is equipped with omni-directional microphone 5, for detecting closest to the received noise signal of high directional microphone, and
Since the second high reflection signal for being directed toward Mike and receiving reflecting surface 6 has pedestal 1 since reflecting surface 6 is arranged on pedestal 1
The noise that body structure generates is issued by reflecting surface 6, is arranged near the second high directional microphone 4 and equal omni-directional Mike is arranged
Wind 5 can effectively receive noise signal, and remote speech must be protected when acquiring using the high directivity microphone of acquisition device
Card can collect remote speech, and 2 at least two groups of pickup cartridge and staggered in the application are compared to generic array formula and set
It sets, is arranged in the noise for the capture surrounding that omni-directional microphone 5 can be balanced on pickup cartridge 2, and small in size, array setting is picked up
The noise Rx at 2 center of sound tube and the noise Rx deviation of two sides are more, keep processing difficult, as a result inaccurate, i.e., the application is set
The more pickup cartridges 2 set keep noise processed simple, and the noise signal of feedback is uniform, and are equipped with accommodating pickup in the pedestal 1
The shell 8 of pipe 2,8 one end face of shell are equipped with through-hole and inner sidewall and are equipped with noise-reducing structure, can be becalmed gear by shell 8
Rain, not only can direct contact to avoid air-flow and raindrop to microphone, and can be with a degree of block noise, and due to disappearing
Sound structure can eliminate the noise of echo and shell 8 itself in shell 8, so that noise in shell 8 is in good level, avoid
Interference to the first high directional microphone 3 and the second high directional microphone 4, and using being arranged in 2 free end end of pickup cartridge
The first high directional microphone 3, can the shortest time most directly receive sound source at remote speech, the second high directional microphone 4
Phonetic incepting at most of sound source after capable of receiving the first high directional microphone 3 is matched with reflecting surface 6, and due to pickup cartridge
It is small in size after 2 arrangements, a certain single human body or other sound sources can be more accurately directed at, are not easy to be done by noise near at sound source
It disturbs, when especially having at sound source compared with strong background noise, the noise signal that the application pickup cartridge 2 is not only fed back uniformly is convenient for handling,
And the first high directional microphone 3, the second high directional microphone 4, reflecting surface 6 can high directivity and abundant reception target sound source voices
First high 3 signal of directional microphone is formed the first main signal by filter circuit and gain circuitry later, by second by signal
High 4 signal of directional microphone by squelch circuit, will be handled well later by filter circuit and by 5 signal of omni-directional microphone
Circuit signal, which is superimposed to form subtracting each other between signal and complete denoising, forms the second main signal, the first main signal and the second main signal
Superposition, which enhances and carries out array algorithm, completes output, and can be formed and be linked with video model, and the pedestal 1 is equipped with driving base
The turntable 7 of 1 rotation of seat, i.e., rotated together with the camera for acquiring video, and pass through image size in video by pickup cartridge 2
Calculate sound source distance.
The pedestal 1 is equipped with the driving assembly that moves axially along pickup cartridge 2 of driving reflecting surface 6, by by reflecting surface 6
It can be moved axially back and forth along pickup cartridge 2, can complete sound-source signal of the different sound sources apart from lower reflection can accurately converge to second
On high directional microphone 4, the range measurement of sound source can be formed by video between the calculating of image size or array microphone
Deviation of signal be calculated, or make that additional ranging component, such as laser ranging component is arranged.
Position on the pedestal 1 and between neighboring reflection face 6 is equipped with poly- sound block, further increases reflecting surface 6
Product, converges to more sound source models on the second high directional microphone 4, the poly- sound block is detachably connected on pedestal 1, is made
Structure adapts to the variation under varying environment, if sound source more recently condition does not have to install poly- sound block, reduces volume, described is poly-
Sound block is equipped with inserted block, and the pedestal 1 is equipped with the annular groove matched with inserted block, is cooperated by slot and convex block, easy for installation,
Structure is simple, is equipped on the outside of the reflecting surface 6 by the concave ring of sound reflection, and sound reflection is referred to that sector signal passes through at sound source
Concave ring multiple reflections are crossed, the direction toward pickup cartridge 2 is deviateed, enable at sound source that signal is less to be received by omni-directional microphone 5, outside
Portion's noise is also less to make signal at sound source be strengthened by 1 surface reflection of pedestal to the second high directional microphone 4, reflection
The concave ring and annular groove of sound can be same structure, keep overall structure more compact and reasonable.
Pickup cartridge 2 is rotatably connected on respectively on pedestal 1 on the pedestal 1, and the reflecting surface 6 is followed by corresponding
Pickup cartridge 2 rotate, so that pickup cartridge 2 is relatively rotated, i.e. more pickup cartridges 2 can be formed similar to fan-shaped shape, more accurately
The signal of cone that issues of reception sound source, and can the emerging microphone reception of a degree of 2 middle part omnidirectional of reductions pickup cartridge
Sound-source signal makes signal at sound source be strengthened.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
