Below, enumerate preferred embodiment and coordinate accompanying drawing to be described in detail technical characteristic of the present invention.
The audio control method of the portable electronic equipment that a preferred embodiment of the present invention provides is applied to portable electronic equipment 10.As shown in Figure 2, this portable electronic equipment 10 can be smart mobile phone or panel computer, this portable electronic equipment 10 includes memory buffer 14 and the multimedia player 12 that is connected with this memory buffer 14 and audio output unit 18, and can perform audio frequency control program 16.
This audio control method comprises the following steps:
First, refer to Fig. 2, first perform step S10.Multimedia player 12 is by voice data transmission to be played and be stored to memory buffer 14, then this voice data is sent to audio output unit 18 (i.e. step S11) by memory buffer 14.This memory buffer 14 is the memory buffer (Audio FIFO Buffer) of audio frequency crossfire, and this audio output unit 18 is for being built in the loudspeaker of portable electronic equipment 10, or be the circumscribed earphone or circumscribed loudspeaker that are electrically connected with portable electronic equipment 10.
Refer to Fig. 1, when after multimedia player 12 audio reception instruction (i.e. step S20), perform step S21 immediately and judge whether this audio instructions is stop audio frequency or suspend audio frequency.
When judging audio instructions that multimedia player 12 receives as stopping audio frequency or suspending audio frequency, the volume of the first storing audio output unit 18 of this multimedia player 12 also as current volume value (i.e. step S22), then performs audio frequency control program 16 in step S23.
When this audio frequency control program 16 obtain current volume value with stop audio frequency or suspend audio frequency audio instructions after, audio frequency control program 16 controls fade out (i.e. the step S24) that audio output unit 18 carries out volume, its step S13 sound intermediate frequency control program 16 being equal to Fig. 2 downgrades the volume of audio output unit 18, then gets back to step S20 and waits for audio instructions.Wherein, the instruction of this audio instructions for being inputted according to the demand of itself by user.
Further illustrate audio frequency control program 16 to control audio output unit 18 in step s 24 which and carry out the mode that volume fades out.
Audio frequency control program 16 is current volume value is gradually reduced to zero in the given time in equally spaced mode.This audio frequency control program 16 first sets and performs time numerical value, and this execution time numeric representation in the given time audio frequency control program 16 need downgrade the number of times of volume.Current volume value is obtained unit volume value divided by execution number of times by this audio frequency control program 16 again.This unit volume value represents that audio frequency control program 16 downgrades the value of the volume of audio output unit 18 at every turn.Thus, audio frequency control program 16 downgrades volume gradually in the given time thus realizes fading out of volume.

In addition, when multimedia player 12 judges that audio instructions not stops audio frequency or suspends audio frequency in the step s 21, perform step S30 and judge whether audio instructions is audio plays, when judged result is "Yes", performs step S31 and judge whether current volume value exists.When judging that current volume value does not exist, multimedia player 12 immediately storing audio output unit 18 volume and as current volume value (i.e. step S32); Then perform step S33 and perform audio frequency control program 16, this audio frequency control program 16 controls fade in (i.e. the step S34) that this audio output unit 18 carries out volume.As shown in the step S13 of Fig. 2, this audio frequency control program 16 increases the volume of audio output unit 18.After the volume completing audio output unit 18 controls, return step S20 and wait for audio instructions.
Otherwise, when being judged as that current volume value exists, performing step S33 and performing audio frequency control program 16, then controlling fade in (i.e. the step S34) that this audio output unit 18 carries out volume, getting back to step 20 after having controlled and wait for audio instructions.
Further illustrate audio frequency control program 16 in step S34, to control audio output unit 18 carry out the mode that volume fades in.
Audio frequency control program 16 is in the given time the volume of audio output unit 18 is increased to current volume value gradually from zero in equally spaced mode.Wherein, audio frequency control program 16 in advance setting performs time numerical value, this execution time numeric representation audio frequency control program 16 needs the number of times increasing audio output unit 18 volume in the given time, again the schedule time is obtained the unit interval divided by execution number of times, this unit interval represents that audio frequency control program 16 increases the interval time of the volume of audio output unit 18 at every turn, again current volume value is obtained unit volume value divided by execution number of times value, this unit volume value represents that audio frequency control program 16 increases the value of the volume of audio output unit 18 at every turn.
Therefore, when user inputs audio plays instruction, the volume being controlled audio output unit 18 by audio frequency control program 16 increases as current volume value in the mode of fading in by zero volume gradually, to reduce initial volume during automatic playing audio-fequency data, audio output unit 18 is avoided just to start exported volume excessive and frighten user.
