Fig. 2 is the schematic flow sheet of the method for automatic adjusting output volume according to the invention.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the equipment of automatic adjusting output volume provided by the invention.
Fig. 1 is the structural representation of embodiment of the equipment of automatic adjusting output volume according to the invention; Comprise terminal T1 and the second equipment T2 that is connected to terminal T1; Said terminal T1 comprises the first sound receiver M11 and intelligent control module M13; Said intelligent control module M13 further comprises comparator M131, MCU Microprocessor Control Unit M132, programmable gain amplifier M133, and the said second equipment T2 comprises the second sound receiver M12 and loud speaker M14.
The user is when using said loud speaker M14 to listen to said terminal T1 playing back music or FM etc.; The said first sound receiver M11 and the second sound receiver M12 are in opening; The said first sound receiver M11 places first acoustic environment; Reception is from first voice data of first acoustic environment, and the said second sound receiver M12 places second acoustic environment, receives the rising tone sound data from second acoustic environment.Said first acoustic environment for example can the person's of being to use pocket or knapsack in, the residing indoor or outdoor environment of head that said second acoustic environment for example can the person of being to use.
The control of said loud speaker M14 output volume and being adjusted among the said intelligent control module M13 is carried out; Said comparator M131 is connected with the said second sound receiver M12 with the said first sound receiver M11; Said first voice data and said rising tone sound data are imported said comparator M131, the value after the comparison is imported said MCU Microprocessor Control Unit M132 as current wave volume data.
Said MCU Microprocessor Control Unit M132 is connected with said comparator M131; Said MCU Microprocessor Control Unit M132 preestablishes a primary data as the valve value; Said current wave volume data and said valve value are compared; To compare gained result output volume data by way of compensation, and generate an offset, said offset will be imported said programmable gain amplifier M133 according to said compensation output volume data;
Said programmable gain amplifier M133 is connected with said MCU Microprocessor Control Unit M132, and adjustment outputs to the compensation rate of said loud speaker M14 according to said offset, controls the output volume of said loud speaker M14, reaches the effect of automatic adjusting output volume.
Said offset can be divided into several grades; The said first sound receiver M11 receives from first voice data of first acoustic environment and said second sound receiver M12 reception and differs big more from the rising tone sound data of second acoustic environment; Relatively the current wave volume data value of back gained is also big more; The offset grade is also just high more, and the compensation rate of output is also just big more; When the current wave volume data value of back gained relatively was less than or equal to said valve value, system is thought did not automatically need compensation, and said loud speaker M14 output volume remains unchanged.
Further consult shown in the accompanying drawing 1; Said MCU Microprocessor Control Unit M132 further comprises a switch control assembly; Control the switch of the said first sound receiver M11 and the second sound receiver M12, avoid two sound receivers to be in opening always.For example, can setting program control the said first sound receiver M11 and the second sound receiver M12 opened once at interval in ten minutes.
Fig. 2 is the schematic flow sheet of the method for automatic adjusting output volume according to the invention, comprises the steps:
Step S21 a: initial value is set as the valve value.Second equipment that will be used to listen to links to each other with the terminal, and makes the function such as music or FM at terminal be in opening, and system is provided with an initial value in advance as the valve value.
Step S22: first sound receiver receives first voice data.First sound receiver is placed first acoustic environment and makes it be in opening, be used to receive first voice data from first acoustic environment.
Step S23: second sound receiver receives rising tone sound data.Second sound receiver is placed second acoustic environment and makes it be in opening, be used to receive rising tone sound data from second acoustic environment.Step S22 and step S23 enforcement each other have no special requirements in proper order.Said first acoustic environment for example can the person's of being to use pocket or knapsack in, the residing indoor or outdoor environment of head that said second acoustic environment for example can the person of being to use.
Step S24: produce output offset to current output volume.Because first sound receiver and second sound receiver are among the different audio environment, the voice data that both receive is different; The rising tone sound data that first voice data that first sound receiver is received and second sound receiver receive compares and draws current wave volume data; For example can rising tone sound data value be deducted the first voice data value, with the difference of gained as current wave volume data.The predefined valve value of current wave volume data and system is relatively drawn compensation output volume data, and produce output offset current output volume according to compensation output volume data.
Step S25: regulate output volume according to the output offset.According to output offset adjustment output compensation rate, thereby regulate output volume automatically, reach the effect of automatic adjusting output volume.For example system can be divided into several grades with offset in advance, and the output offset of current output volume is reached a certain grade, then produces the corresponding output compensation rate of this grade, regulates output volume according to said output compensation rate.Said offset grade can be natural number.Differ big more between said first voice data and the said rising tone sound data, relatively the current wave volume data value of back gained is also big more, and the offset grade is also just high more, and the compensation rate of output is also just big more; When the current wave volume data value of gained relatively was less than or equal to said valve value, system is thought did not automatically need compensation, and output volume remains unchanged.
Said method also can further comprise a controlled step, controls first sound receiver and second sound receiver is periodically opened, thereby avoids two sound receivers to be in opening always.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
