Pendulum position, enrolls simultaneously, carries out audio mixing establishment the most again.Many microphones are used to carry out the mode of stereophonic recording, strongly professional, need
Wanting sound pick-up outfit and the Professional knowledge of specialty, the requirement to stereophonic recording is the highest.
Summary of the invention
This utility model aims to provide a kind of recording microphone, and many microphones of employing existed to solve prior art are carried out
The standard of stereophonic recording, strongly professional, need sound pick-up outfit and the Professional knowledge of specialty, to the requirement of stereophonic recording very
High problem.
The technical solution of the utility model is: a kind of recording microphone, it is characterised in that include emulating acoustics connector,
Decoration protection net, emulated artificial ear, microphone sound head, audio frequency regulation terminal and audio output port, the root of emulated artificial ear
It is connected to the outer end of a basal part of the ear body, is provided with the auditory meatus through with the inner of basal part of the ear body at this emulated artificial ear, in this auditory meatus
End is equipped with microphone sound head；The inner of a basal part of the ear body is respectively embedded at the two ends of the emulation acoustics connector of cydariform or cylinder,
And be provided with emulated artificial earmuff decorations protection net inside；This emulation acoustics connector is provided with audio frequency regulation terminal and
Audio output port, this audio frequency regulation terminal and audio output port electrically connect with this microphone sound head routine.
The utility model has the advantages that: by means of the HRTF impact on sonic transmissions, to sound in simulation human physiological structure
The various functional effect features such as the reflection of ripple transmission, diffraction, refraction, poly-sound, have reappeared the various impacts of human ear acoustic surrounding, have made
Recording effect reaches the effect level of the actual audition of human ear the most really, makes sense of hearing more on the spot in person, truly, has stronger
Feeling of immersion.This microphone is with headphone monitor hole simultaneously, can listen to the sound effect enrolled in real time.

Detailed description of the invention
See Fig. 1～Fig. 4, this utility model one recording microphone, it is characterised in that include emulating acoustics connector 1,
Decoration protection net 2, emulated artificial ear 3, microphone sound head 4, audio frequency regulation terminal 5 and audio output port 6, emulated artificial ear 3
Root be connected to the outer end of a basal part of the ear body 7, be provided with the auditory meatus 8 through with the inner of basal part of the ear body 7 at this emulated artificial ear 3,
The inner of this auditory meatus 8 is equipped with microphone sound head 4；One is respectively embedded at the two ends of the emulation acoustics connector 1 of cydariform or cylinder
The inner of basal part of the ear body 7, and it is provided with the decoration protection net 2 that emulated artificial ear 3 is covered on the inside；At this emulation acoustics connector 1
It is provided with audio frequency regulation terminal 5 and audio output port 6, this audio frequency regulation terminal 5 and audio output port 6 and this microphone sound head 4
Conventional electrical connection, the input of microphone and the gain of earphone output are adjusted by its sound intermediate frequency adjustable side 5；Audio frequency exports
Mouth 6 has audio output interface and headset output interface, can monitor while recording.
Described emulated artificial ear 3 forms according to the emulation of Human Physiology ear, comprises auricle, external ear, auditory meatus a few part group
Becoming, the effects such as reflection, refraction, diffraction, poly-sound are played in the transmission to sound wave.Microphone sound head 4 is placed in emulation auditory meatus, sound wave
Microphone sound head 4 is passed to by the impact of the various structure of emulated artificial ear 3.Every have reflection, refraction, diffraction, poly-to sound wave
The structure of sound, to reach to distinguish sound phase place and the effect of acoustical signal spatial information, all protection of the present utility model it
In.
Described acoustics connector 1 itself is except having fixing emulated artificial ear 3(basal part of the ear body 7), decoration containment envelope 2,
Outside audio frequency regulation terminal 5 and audio output port 6 act on, also there is the distance between the emulated artificial ear of control left and right, produce sound
The functions such as the reflection of ripple transmission, diffraction, refraction.Acoustics connector 1 surface is to have curved surface or face directly or the structure dress of a combination thereof
Put；Can also be to there is protrusion or depression, to be different from the symmetry or non-right of two ends (emulated artificial ear junction) physical arrangement
Adult, can also stretch to change the distance and position between artificial ear 3.This structure takes HRTF(head-related transfer function
Head-related transfer function, is abbreviated as HRTF) impact on sound wave, to distinguish each position of acoustics connector
Different transmission impacts on sound wave, reach to distinguish sound phase place and the effect of acoustical signal spatial information.Employing normal experiment can
The combinative structure of acoustics connector 1 with miscellaneous part to be met above-mentioned requirements.
Described decoration protection net 2 has decoration and protection simulation artificial ear 3 and the effect of microphone sound head 4, with
Time play the protective effect of entrant sound Radix Saposhnikoviae dustproof and anti-explosion, this decoration protection net 2 is not limited to circle or taper, and any have this
The protection device of functional effect.
This utility model simulates people in actual acoustic surrounding, and human organ is to the various shadows during sonic transmissions
Ring.The various sound waves that human ear is heard, pass to ear drum membrane through auricle, external ear, auditory meatus；In transmitting procedure, the auricle of people, ear
Road, the first-class various organs of people all can produce certain impact to refraction, diffraction and the diffraction of sound wave.In acoustics, this impact
It is referred to as " head-related transfer function " impact, is called for short HRTF.Just because of the impact of HRTF, the big brain-capacity of people is rule of thumb sentenced
Break and the azimuth-range that sound sends.Even if people blindfolds also can judge direction and the distance that sound sends, here it is lean on
The judgement that the experience that brain affects according to HRTF is made.
This utility model by emulated artificial ear load microphone the way of recording, be simultaneously introduced in HRTF affect because of
The application of the routine techniques means such as the algorithm that element and partial spatial information strengthen, has reproduced real human body organ to sonic transmissions
Affect environment.The effect that recording realizes reached the truly feels of people's sense of hearing, it is possible to distinguish the direction of sound source, acoustic pressure size
Change, it is achieved that the true immersive effects of interactive recording.
