Description
Technical field
This utility model is related to a kind of outer playback matter automatic regulating system of mobile phone, is primarily adapted for use in mobile phone, PAD etc. mobile logical
News equipment, belongs to electronic information technical field.
Background technology
Mobile phone has become a part for people's life, and the various use functions of mobile phone are also more and more, and mobile phone is because of it
It is easy to carry and convenient and people call, by increasing people favor, has become people and carry with requisite thing
One of product.The ringing volume of wherein existing mobile phone usually manually adjusts volume, so either in environment noise
Miscellaneous downtown area or quiet office is indoor, and the tinkle of bells size of mobile phone can not be automatically adjusted, the mobile phone of this adjustment structure
If in noisy downtown area ringing sound of cell phone it is too small if can't hear ringing sound of cell phone, user can be made to answer in time；In addition such as
Fruit is in quietly office interior, because ringing sound of cell phone is excessive, can interfere, so that having influence on indoor remaining employee's of office
Normal work.And, many people like listening music with mobile phone, but to wear and have damage to ear if earphone, with what is put outward
Talk about that to put power outside a lot of mobile phones not big enough, and reach also easy distorsion if maximum.
Therefore, related researcher is studied the outer playback matter of mobile phone, existing to can automatically imitate the outer playback matter of standard
Automatically calibration sound field and automatic tonequality regulation technology are mostly using digital room processing system.Existing electronic terminal product, including

Lifted on low frequency and definition.
Further, commence play out in audio file, if user does not make regulation, the numeral to the tonequality of audio file
Processor DSP obtains the moment external voice size information that audio file is commenced play out, used as initial outward sound size data
Used as setting value, simultaneity factor records the moment corresponding audio file tonequality information, used as initial tonequality data.
Further, if user adjusts to tonequality, the tonequality information after system record adjustment, as initial tonequality number
According to, while digital processing unit DSP obtains correspondence moment outside environmental sounds size information, as initial outward sound size data
As setting value.
Further, the digital processing unit DSP is by real-time outside environmental sounds size information and initial outward environment
Sound size data is compared, if exceeding setting value, the equalizer EQ of the digital processing unit DSP controlled output modules is in
High frequency is lifted, the corresponding volume increased in tonequality；If conversely, real-time external ambient sound size information is less than initial outward
Ambient sound size data, the equalizer EQ of the digital processing unit DSP controlled output modules is on low frequency and definition is lifted
It is adjusted.
Further, the output module includes the multiple audio amplifiers in power amplifier and multi-channel system.
Further, the audio file is sent to digital processing unit DSP by audio decoder signal.
Further, the speaker is divided into single speaker and twin loudspeaker.
Further, in the multi-channel system in the digital processing unit DSP controlled output modules each audio amplifier volume,
Exported each volume of sound channel loudspeaker to coordinate.
The beneficial effects of the utility model are：This utility model automatically adjusts sound according to the sound size of external environment condition
Matter, when external environmental sounds than it is larger when, the equalizer EQ in tonequality just focuses on medium-high frequency and is lifted, to increase volume；
When external environmental sounds are smaller, the equalizer EQ in tonequality is just selected on low frequency and definition is lifted, and makes overall sound
Matter has one than larger lifting.
The deflection of the change adjustment tonequality according to environment of this utility model intelligent so that user has one to compare
Good experience；Comparison is portable, and lifting volume can be carried out without external voice box；The sense of hearing experience of user is taken into full account, in environment
When comparison is noisy, the gain of volume and medium-high frequency is increased emphatically so that user can not hear music；It is more quiet in environment
When, being lifted in tonequality, experience is more preferable.
