Description
Technical field
The present invention relates to a kind of earphone, relate in particular to a kind of automatic tuning earphone and earphone tuning method.
Background technology
The frequency range that ear can be heard is usually between 16 to 1600Hz.Broadly, as long as can sonorificly all be called the news source, the various audio-visual productss of picture, as walkman, personal data processor (PDA), MP4 and mobile phone etc. all is the news source, but having only the news source is to have no idea to produce the sound that we can hear, must produce, transmit electronic signal by relevant electronic installation, and expand to put by loud speaker and become the sound that our people's ear can be heard.Further saying is, as long as can produce sound, and can receive the equipment of electronic signal, can be called loud speaker.
At present, the kind of loud speaker is a lot, a kind of in the dynamic planar loudspeakers: earphone is exactly a kind of in the loud speaker.Along with development of electronic technology, various audio-visual productss, universal all the more as walkman, personal data processor (PDA), MP4 and mobile phone etc., correspondingly, being used for the said goods answers the earphone of use and is able to extensive use simultaneously, use the people of earphone can non-interfering enjoy music or reception information, bring great convenience to people.
Yet, because everyone ear shape structure is all inequality, somebody's duct is darker, somebody's duct broad, the effect that is caused by external ear, duct or the like, can make sound that different sound performances is arranged in everyone duct, therefore, having caused identical product is identical sound tonequality performance when test, but after having arrived in user's hand, the problem that but produces different sound tonequality takes place, and has had a strong impact on the tonequality performance of earphone and user's auditory perception.
Make with a earphone and arrived the acoustical quality that produces energy the best in different users's hand, then need carry out tonequality when the different users uses earphone regulates, and earphone of the prior art, the adjustment of sound size and acoustical quality is adjusted control by playback equipment and is realized, earphone itself can't be adjusted acoustical quality, therefore, make the relative different users of earphone can not all give play to best acoustical quality, thereby the user also is without access to best auditory perception.
Therefore, need a kind of can be inequality and regulate tonequality automatically according to different users's duct, thereby given play to the automatic tuning earphone of best acoustical quality.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art provide a kind of can be inequality and regulate tonequality automatically according to different users's duct, thereby given play to the automatic tuning earphone of best acoustical quality.
Another object of the present invention is to provide a kind of can be inequality and regulate tonequality automatically according to different users's duct, thereby given play to the earphone tuning method of best acoustical quality.
For achieving the above object, automatic tuning earphone provided by the present invention comprises the audio signal loader, loud speaker, microphone, but access/memory body and arithmetic unit, described audio signal loader has the test audio signal of standard and exports described test audio signal, the test audio signal of described loud speaker received audio signal loader output also produces sound, described microphone stretches in the human antrum auris, described microphone receives loud speaker and is passed to the sound in the human antrum auris and exports the contrast audio signal, but the contrast audio signal of described access/memory body access microphone output, described arithmetic unit extracts compare calculation process and draw the frequency that needs reinforcement of test audio signal and contrast audio signal, but the described frequency that needs reinforcement of described access/memory body access, but described arithmetic unit carries out computing according to the audio signal of the frequency of the need reinforcement of access/memory body access and audio frequency outlet terminal device output to external world to be strengthened handling, and the audio signal of external audio outlet terminal device output is strengthened handling the back through described arithmetic unit and inputed to described loud speaker by described audio signal loader.
Earphone tuning method provided by the present invention comprises the steps: the test audio signal of outputting standard; Receive described test audio signal and convert sound to and play; Reception is passed to the sound in the human antrum auris and converts the contrast audio signal output to; Described contrast audio signal is carried out access; Extract compare calculation process and draw the frequency that needs reinforcements of test audio signal and contrast audio signal, the described frequency that need reinforcement of access; According to the frequency of the need reinforcement of access to external world the audio signal of audio frequency outlet terminal device output carry out computing and strengthen handling and form and strengthen audio signal; Receive described reinforcement audio signal and convert voice output to.
As mentioned above, automatic tuning earphone of the present invention and earphone tuning method are by sending a test sound to human antrum auris, sound produces the different sound that returns at the different human body duct, the Frequency point that the voice signal that goes out to return by internalarithmetic need be strengthened, the Frequency point of strengthening as required compares computing to required played sound signal again, thereby draw the reinforcement audio signal, play to human antrum auris, whole tuning process is regulated automatically by earphone, need not manual operation again, therefore, automatically the tuning earphone has agility, and accuracy is easy to use, the sound performance that plays out is good, all can show the sound effect of the best to different users's duct.
