Embodiment one
Referring to Fig. 1, a kind of adjusting method for microphone sound equipment integrated equipment that first embodiment of the invention provides, including
Step S01 to step S04.
Step S01 picks up the sound vocal print of user.
Specifically, passing through microphone sound equipment integrated equipment when user is sung using this microphone sound equipment integrated equipment
In the sound such as mark core receiver receive the sound vocal print that device obtains user.
Step S02 carries out prime audio processing and digitized processing to the sound vocal print, to obtain an amendment sound
Signal.
Specifically, being limited to the original that mark core receiver is excessively close (only 5CM) with unit Horn loudspeaker box, transmits according to sound
The distribution such as (Fig. 2) will be presented in reason, the directionality of unit loudspeaker, by direct width be mapped to mark core receiver pickup (by microphone by
Talk about device and have characteristic influence by oneself, with reference to the cardioid of Fig. 3), it causes to repeat amplification in route and positive feedback is resonated, and generate self-excitation, make a whistling sound
It cries, fly the distortion phenomenons such as mark, cause user's experience very poor, it therefore, in embodiments of the present invention, can be by changing the sound
The waveform of speech line, the phase of modulation or the delay sound vocal print or the enhancing sound vocal print together with wave component in
It is one or more that prime audio processing is carried out to sound vocal print, and the sound vocal print is acquired in digital form, with
Obtain a voice signal；The voice signal is converted, is filtered, valuation, enhancing, compression, identifying processing, to obtain
State amendment voice signal.
Step S03 adjusts the angle of phonation unit according to the amendment voice signal.
Specifically, the receiver 360 ° of ranges at different frequencies for obtaining microphone sound equipment integrated equipment can be first passed through
Interior curvilinear characteristic；It obtains and is built after carrying out digital conversion with the biggish frequency of pre-programmed curve feature difference in the curvilinear characteristic again
Mould samples, compares, phase shift, reverse phase processing, to obtain the angle for needing to adjust.In implementation process, cardioid and super core shape are selected
Structure advantageously accounts for the interference caused by 90-270 degree and lower unit loudspeaker of microphone receiver direction, we are with cardioid
Illustrate for case, microphone sound equipment integrated equipment about 5CM with a distance from loudspeaking speaker in the pickup of near field, the cardioid that such as (Fig. 3) shows
360 write music in line, it has been found that the sound wave interference between 90-270 degree is stronger, will interfere stronger frequency statistics come out (such as
1K, 5K, these interference signals will influence whether microphone sound equipment integrated equipment receiver analog signal after amplification, with unit
Loudspeaker forms positive feedback and self-excitation is caused to be distorted), the sound arrived after these Carrkioids are connect changes into digital signal by amplification
Post-sampling, which is interfered, to carry out digital sample after strong frequency (such as 1K, 5K) signal, models, compares, phase shift, changing into after reverse phase processing again
To loudspeaker horn, resetting the sound wave come out in this way will be picked up by microphone receiver once again for amplification after analog signal, just will form
The partial cancellation of phase not will form positive feedback self-excitation and utter long and high-pitched sounds distortion, the phasing that these different frequencies will be different, just
It can solve big volume, near field, undistorted phenomenon.
Step S04 drives the phonation unit sounding according to the amendment voice signal.
The present invention passes through the adjusting method of above-mentioned microphone sound equipment integrated equipment, in use, first picking up the sound sound of user
The sound that line, i.e. user issue；Prime audio processing and digitized processing are carried out to the sound vocal print again, repaired with obtaining one
Positive voice signal, and then reduce positive feedback resonance, thus avoid microphone sound equipment integrated equipment generation self-excitation, utter long and high-pitched sounds, fly mark etc.
Distortion phenomenon improves sound quality；Then the angle of phonation unit is adjusted according to the amendment voice signal；According to the amendment sound
Sound signal drives the phonation unit sounding, so that the sound that phonation unit issues largely is directly entered in the ears of user,
And then direct sound wave ratio is improved, so that user is not heard the sound that microphone sound equipment integrated equipment is issued clearly.
