Abstract
The invention discloses a method for regulating sound volume of an audio signal sent out by a mobile phone, by which corresponding sending loudness is calculated based on a setting sound volume grade of a microphone; an input audio signal of the microphone is enlarged according to the sending loudness and then the enlarged audio signal is sent out. The sound volume options of the microphone are increased and users can choose sound volume of the microphone in the sound volume options of the microphone, and then the sound volume is enlarged by an audio amplifying circuit to regulate sound volume heard by the other party. The invention has the advantages of avoiding inconvenience to the other party because of too large or too small sound of one party, and having more ideal talking result.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method that mobile phone sends the volume of audio signal of regulating.
Background technology
Along with the continuous development of the communication technology, mobile phone technique is also constantly brought forth new ideas, and as the mobile phone of end product, executable operation is more and more, and function from strength to strength.And conversation is as the basic functions of mobile phone, and its stability and practicality also should constantly be enhanced.
In communication process, the size of In Call directly has influence on calling quality, can regulate the size of In Call at present by the volume that receiver is set, for example, can transfer the volume of receiver more greatly in the time of out of doors, when participating in a conference, can transfer the volume of receiver smallerly, so just can hear more moderate sound.But, by the volume of adjusting receiver, the volume of uppick that can only draw oneself up, and can not control the volume that the other side hears own sound.
Under real-life a lot of situations, such as in session the time phone that must answer, but the volume of speaking again must be lower, this just may cause the other side not hear, if just hearing, the other side must not repeat one after another, so just both call sides has all been caused inconvenience, in this case, because existing mobile phone lacks corresponding setting option and function, make speech quality be greatly affected, therefore, just need a kind of method more targetedly to regulate the volume that the other side in the communication process hears own sound.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method that mobile phone sends the volume of audio signal of regulating, this method can be provided with the user according to the speak custom of sound size of current environment of living in or oneself, no matter oneself speaks can both make the other side hear the sound that volume is suitable loud or for a short time.
For solving the problems of the technologies described above, a kind of method that mobile phone sends the volume of audio signal of regulating of the present invention, this method is according to the transmission loudness of the microphone volume rating calculation correspondence that is provided with, according to sending loudness the audio signal of microphone input is amplified, send the audio signal after amplifying.
Further, adopt following steps that the microphone volume grade is set: increase the microphone volume option in mobile phone, the user selects the microphone volume grade in the microphone volume option.
Further, the process of the audio signal of microphone input being amplified according to transmission loudness comprises following substep: step 1: microphone is modulated the voice signal of user's input, and the audio signal that modulation is finished sends to audio frequency transmission amplifying circuit; Step 2: audio frequency sends amplifying circuit and obtains transmission loudness, according to sending loudness audio signal is amplified.
Further, after calculating corresponding transmission loudness, before the audio signal of microphone input being amplified according to transmission loudness, will send loudness and deposit in the microphone gain register, audio frequency sends amplifying circuit and obtain transmission loudness from the microphone gain register.
Further, the user selects the microphone volume grade in the microphone volume option after, the microphone volume level data of microphone volume grade correspondence is deposited in the non-volatile RAM of mobile phone flash memory, use this microphone volume level data to calculate corresponding transmission loudness.
Further, audio frequency transmission amplifying circuit is integrated in the microcontroller of described mobile phone.
In sum, the present invention is by increasing microphone (Microphone, be called for short: MIC) volume option, the user selects the MIC volume in MIC volume option, amplification through audio amplifier circuit, thereby regulate the volume of the sound that the other side hears, avoid too small or excessively make troubles, make communication effect ideal more to the opposing party because of side's sound.
Description of drawings
Fig. 1 is the flow chart of method of the present invention;
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated:
As shown in Figure 1, be a kind of flow chart of method that mobile phone sends the volume of audio signal of regulating of the present invention, this method comprises the steps:
Step 101: in mobile phone, increase the microphone volume option;
The microphone volume option can adopt various contextual models are set, as, indoor, outdoor, meeting etc.; Also can adopt the mode that volume progression is set, as, the descending 1-7 level that is divided into of volume.
Step 102: the user selects the microphone volume grade in the microphone volume option;
The user can select suitable microphone volume grade according to the custom of self the current environment of living in or the sound size of oneself speaking;
For example, when participating in a conference, the user can select conference model or higher volume progression, in conference model or select higher volume progression, when conversation, even the user speaks that sound is very low can not to make the other side not hear user's sound yet, still can make the other side hear the sound that volume is suitable;
As user out of doors the time, because user's voice can be bigger,, can not make the other side hear excessive volume even user's one's voice in speech is bigger like this so can select outdoor pattern or lower volume progression yet, the other side is felt awkward or discomfort.Certainly, if the voice of user own is lower, also can select conference model or higher volume progression in the time of out of doors.
Step 103: system stores the microphone volume level data of the microphone volume grade correspondence that the user selects;
In the present embodiment, the microphone volume level data can be stored into mobile phone flash memory (flash), (Non-Volatile ram is called for short: NV) non-volatile RAM.
Step 104: when conversation, system reads the microphone volume level data;
In the present embodiment, system reads out the microphone volume level data from the NV district of flash.
Step 105: system uses the microphone volume level data to calculate the transmission loudness of this microphone volume level data correspondence;
Send the absolute loudness that loudness is meant the audio signal that signalling sends, reflection be the volume of audio signal recipient uppick.
Step 106: the transmission loudness that system will calculate deposits in the microphone gain register;
Step 107: microphone is modulated the voice signal of user's input, and the audio signal that modulation is finished sends to audio frequency transmission amplifying circuit;
Step 108: audio frequency sends amplifying circuit and read transmission loudness from the microphone gain register, according to sending loudness the audio signal that receives is amplified;
Audio frequency transmission amplifying circuit can be integrated in microcontroller, and (Micro Controller Unit, be called for short: MCU), audio frequency sends amplifying circuit and audio signal is amplified with suitable multiplication factor according to sending loudness.
Step 109: system sends the audio signal through amplification by antenna.
