Description
Technical field
The utility model relates to a kind of audio output apparatus, especially a kind of tuning earphone.
Background technique
It is well known that existing earphone is varied, but it has a single function, such as: existing earphone when leaving the factory, ear
The sound quality of machine has been fixedly installed, some earphones lay particular stress on bass sound quality, and some earphones emphasize the sound quality etc. of high pitch, at present still
There is no a kind of earphone, can be realized the adjusting to sound quality, the adjusting of individual character cannot be carried out according to the needs of users, do not can be carried out
The volume of high, medium and low sound is screened and is adjusted.Therefore, a kind of tuning earphone of researching and designing, meets music-lover and musical composition
The demand of person is imperative.
Summary of the invention
In view of it is above-mentioned the problems of in the prior art, the purpose of this utility model is a kind of tuning ear of researching and designing
Machine enables a user to complete the adjusting to high pitch, middle pitch and bass.
The utility model is made of signal input module, independent current source module, D/A converter module and tuning module, signal
Input module is connected with independent current source module, master control switch and D/A converter module；Tuning module is by whole control zone and volume
Control zone composition respectively, whole control zone are composed in series by adjusting audio devices and adjusting audio switch；Volume distinguishes control zone
It is made of frequency analyzer parallel connection bass regulation button, middle pitch regulation button, high pitch regulation button and resistance；Whole control zone with
It is in parallel that volume distinguishes control zone；The independent current source module provides electric energy for whole device；The D/A converter module connects
The information of signal input module is received, and the information received is converted into audio output signal；The adjusting audio switch control
System adjusts the open and-shut mode of audio devices, adjusts the volume that audio devices control entire circuit audio；The frequency point
Analyzer can send control signal to bass regulation button, middle pitch regulation button, high pitch regulation button according to the vibration frequency of sound,
Distinguish high pitch, bass, middle section；Bass regulation button, middle pitch regulation button, the high pitch adjusting that the volume distinguishes control zone are pressed
Button is respectively divided into 10 gears, achievable bass area, middle register, treble 0-100% decibel volume adjustment.
After adopting the above structure, whole control zone can realize the adjusting of total volume and the broadcasting of audio and stop function；Sound
Amount difference control zone, the achievable control zone, the i.e. adjusting of the 0-100% decibel of bass, middle pitch and high pitch volume.
The utility model has the beneficial effects that structure is simple, construction is reasonable, easy to use, it had not only been adjustable the volume of earphone, but also
Different sound quality can be adjusted according to the hobby of oneself, meet the different demands of music-lover and musical composition person.
Detailed description of the invention
Fig. 1 is the circuit diagram of the utility model.
Description of symbols: 1, signal input module, 2, independent current source module, 3, D/A converter module, 4, master control switch,
5, adjusting audio devices, 6, adjusting audio switch, 7, frequency analyzer, 8, bass regulation button, 9, middle pitch regulation button, 10,

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Figure 1, in a kind of tuning earphone, by signal input module 1, independent current source module 2, D/A converter module
3 and tuning module composition, signal input module connects with independent current source module, master control switch 4 and D/A converter module；Tuning mould
By whole control zone and volume, control zone forms block respectively, and whole control zone is gone here and there by adjusting audio devices 5 and adjusting audio switch 6
Connection composition；Volume is distinguished control zone and is pressed by the bass regulation button 8 in parallel of frequency analyzer 7, middle pitch regulation button 9, high pitch adjusting
Button 10 and resistance 11 form；Whole control zone is in parallel with volume difference control zone；The independent current source module is whole device
Electric energy is provided；The D/A converter module receives the information of signal input module, and the information received is converted into audio
Output signal；The open and-shut mode for adjusting audio switch and controlling to adjust audio devices adjusts the entire electricity of audio devices control
The volume of road audio；The frequency analyzer can be adjusted according to the vibration frequency of sound to bass regulation button, middle pitch
Button, high pitch regulation button send control signal, distinguish high pitch, bass, middle section；The low pitch of volume difference control zone
Section button, middle pitch regulation button, high pitch regulation button are respectively divided into 10 gears, achievable bass area, middle register, treble 0-
100% decibel volume adjustment.
In practical application, the digital analog converter of D/A converter module receives the output signal of signal input module, and
Convert the signal into music signal output；Whole control zone can realize the function that total volume adjustment and audio play and stop；
The frequency analyzer of volume control zone respectively can distinguish high pitch, bass and middle section according to the vibration frequency of sound, concurrently
Signal is controlled out, and wherein bass frequency range is 0-80HZ, and middle pitch frequency range is 80-200HZ, and high audio frequency range is
