Technical field
The utility model relates to acoustic equipment field, in particular to a kind of multidirectional sound pick up equipment.
Background technique
The labyrinth of human ear not only enables a person to hear sound, but also can also judge the outflow direction of sound, this is because
Ears integrate effect.It is that people rely on the poor volume between ears, time difference and tone color difference to differentiate sound bearing that ears, which integrate effect,
Effect.When sound intensity difference, the distance between sound source and auditor out can be experienced.
In order to make the defective crowd of ear that can also listen to sound in complex environment, be often used microphone apparatus into
Row sound collection, representative therein is hearing aid industry.Directional microphone technology is sound collection skill comparatively ideal at present
Art, he is to make sound that delay occur to change the mesh that phase reaches noise reduction and speech enhan-cement by the combination of two microphones
's.But the complexity of the acoustic environment as locating for people, even uses this technology, and the hearing aid of most expensive is also difficult to solve
More people's communicating questions in noisy environment, according to data statistic analysis it is found that there is presently no any one hearing aid energy is fine
Improve the speech recognition capabilities under noise circumstance in ground.
In addition also by the microphone matrix technology of multiple microphone combinations, noise reduction can be better achieved, but still nothing
Method achievees the effect that accurately to pick up complex environment voice signal.There is such case main the reason is that, due to needing to consider
The aesthetics of sound pick up equipment, it is necessary to volume be made very small, want to realize the highly sensitive of microphone in so small spatial volume

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Embodiment 1
Fig. 1 schematically shows the multidirectional sound pick up equipment of embodiment 1.
As shown in Figure 1, the multidirectional sound pick up equipment 1 including shell 1, pickup cartridge 2 and microphone assembly 3.It is opened inside shell 1
Equipped with cavity 4, microphone assembly 3 is fixedly installed in cavity 4 by gasket, fixed plate or other fixation devices.Microphone
Component 3 is connected with output device, for exporting the sound being collected into.The surface of shell 1 offers circular tone-entering hole 5, picks up
One end of sound tube 2 is fixedly connected with tone-entering hole 5, and the other end connects microphone assembly 3.Pickup cartridge 2 can be installed vertically on shell 1,
It is also possible to have the inclination of certain angle to be installed on shell 1.The pickup cartridge 2 of present embodiment is installed vertically on shell 1.Pickup cartridge
2 be swan-neck, and is made of plastics or metal.The curved pickup cartridge 2 can be snakelike or spiral shape or back-shaped.This
The pickup cartridge 2 of embodiment is spiral shape.The shell 1 of present embodiment is made of high density material, which can be with
For highdensity plastics, metal or timber etc., 1 density of shell is big as a result, sound insulation is good, and the sound collected in shell 1 is not easy
Transmitting mutually.In addition, shell 1 can be formed by multiple panel splicings, shell 1 is removable as a result, facilitates the pickup cartridge of enclosure interior
2 and microphone installation and maintenance.Shell 1 can be polyhedron or sphere, and the shell 1 of present embodiment is polyhedron.Shell
The quantity for the pickup cartridge 2 at least installing a pickup cartridge 2 on each face of body 1, and installing on each face is identical.Further,
The shell 1 of present embodiment is square, and tone-entering hole 5 is opened in the center in each face of shell 1, the quantity of tone-entering hole 5
It is six, and corresponding pickup cartridge 2 is also six, i.e., a pickup cartridge is only installed on each face of the shell 1 of present embodiment
2.It is of course also possible to install two or more pickup cartridge 2 on each face as needed.
In addition, for the convenience for guaranteeing sound pick up equipment installation and putting, the length of the pickup cartridge 2 of present embodiment is identical.
It is mounted on pickup cartridge 2 on each face of shell 1 as a result, can accurately collect the voice signal from all directions.Installation
Identical in the quantity of the pickup cartridge 2 on each face of shell 1, so that the consistency of incoming sound is more preferable, accuracy is more preferable.
At least one curved pickup cartridge 2 is installed on each face of shell 1 of above-mentioned multidirectional sound pick up equipment, is mounted on shell 1
The opening of bending pickup cartridge 2 be connected with tone-entering hole 5, be pointed in different directions, can according to the size of shell 1 itself, shape come
The opening direction of the distance between each built-in bending pickup cartridge 2 and pickup cartridge 2 is set, each built-in bending pickup cartridge 2 it
Between a certain distance is set, can effectively avoid influencing each other for the sound transmitted between Guan Yuguan.Further, it is also possible to according to
Need to select the caliber and length of corresponding pickup cartridge 2, to meet the needs of different.
The working principle of the multidirectional sound pick up equipment of present embodiment are as follows:
The transmission speed V of sound wave is 340m/s, and traditional directive property sound pick up equipment considers the factors such as apparent size, two wheats
Commonly distance L is 10mm, i.e. 0.01m between gram wind.It is now assumed that sound is transmitted from a direction, sound wave is introduced into close to sound source
Microphone enter back into farther away microphone, the sound that two sound receive at this time will have time to difference, when being obtained by calculation
Between it is poor are as follows: 0.01/340=0.0000294s=29.4 μ s, time difference of short duration in this way are very difficult to subsequent acoustic processing.For
More obvious time difference, the multidirectional pickup dress of present embodiment can be realized in the case where not changing device size as far as possible
It sets and increases curved pickup cartridge 2 between multiple microphone assemblies 3, increase the distance between microphone assembly 3 L significantly, away from
After increasing from L, notable difference will occur for the temporal properties such as time, intensity of sound received by each microphone assembly 3, lead to
It is higher processing, the accuracy such as to cross subsequent analysis these apparent differences and can accurately be analyzed sound, be positioned.
Embodiment 2
As shown in Fig. 2, the multidirectional sound pick up equipment of present embodiment and the structure in embodiment 1 are essentially identical, difference exists
In: the shell 1 of present embodiment is irregular spherical surface body, and the shape of pickup cartridge 2 is snakelike and inclination is installed on shell 1.
The shell 1 of present embodiment is divide into upper part and lower part, and the top of shell 1 is divided into spherical shape, and the bottom of shell 1 is flat
Face, facilitate by entire sound pick up equipment be placed on table or other planes on.
Spherical surface along the upper part of shell 1 circumferentially installs multiple pickup cartridges 2, and the shell surrounding of present embodiment is circumferentially arranged
A pickup cartridge 2 is arranged in four pickup cartridges 2, top center.The circumferential direction of shell 1 is mounted on pickup cartridge 2 as a result, can be accurate
Voice signal of the collection from all directions.
The multidirectional sound pick up equipment of the utility model by setting be differently directed, 2 pairs of differences of bending pickup cartridge of same modality
The sound in direction is acquired simultaneously, substantially increases the special of the frequency of different directions voice signal, loudness and temporal properties
Property, for subsequent analysis, comparison and the processing for carrying out different directions signal, provide more complete information.It can be improved Mike simultaneously
The input signal quality of wind component 3 improves signal spectrum, sensitivity and the signal detail otherness etc. of incoming sound.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
