8. A method of adjusting volume, comprising the steps of:
the MIC of the front cavity acquires an environmental audio signal of the sound output part;
the front cavity audio conversion circuit converts the acquired environment audio signals to acquire corresponding environment audio electric signals;
the rear cavity MIC collects external real-time environment sound signals;
the rear cavity audio conversion circuit converts the collected external real-time environment sound signal to obtain a corresponding external real-time environment sound electric signal;
and the processing control module analyzes and processes the environment audio electric signal and the external real-time environment sound electric signal to obtain corresponding environment audio volume data and external real-time environment sound volume data, acquires the required playing volume by combining a pre-stored basic playing volume data ratio, and adjusts and controls the playing volume to be equal to the required playing volume.
9. The method for adjusting volume according to claim 8, wherein the processing control module analyzes and processes the environmental audio electrical signal and the external real-time environmental sound electrical signal to obtain corresponding environmental audio volume data and external real-time environmental sound volume data, obtains the required playing volume by combining a pre-stored basic playing volume data ratio, and the step of adjusting and controlling the playing volume to be equal to the required playing volume specifically comprises:
the processing control module analyzes and processes the environmental audio electric signal and the external real-time environmental sound electric signal to obtain corresponding environmental audio volume data and external real-time environmental sound volume data;
judging whether the ratio between the environmental audio volume data and the external real-time environmental sound volume data is equal to the ratio of the basic play volume data or not by combining the pre-stored ratio of the basic play volume data;
when the ratio of the environmental audio volume data to the external real-time environmental sound volume data is not equal to the ratio of the basic playing volume data, acquiring corresponding required environmental audio volume data according to the ratio of the external real-time environmental sound volume data to the basic playing volume data, and analyzing according to the required environmental audio volume data to acquire corresponding required playing volume;
and adjusting and controlling the playing volume to be equal to the required playing volume.
10. The volume adjusting method as claimed in claim 8, wherein the step of the front chamber MIC acquiring the ambient audio signal of the acoustic part comprises:
the processing control module receives and stores the preset basic playing volume and controls the sound output part to play the preset debugging audio according to the preset basic playing volume;
the MIC of the front cavity acquires a primary environment audio signal of the sound part;
the front cavity audio conversion circuit converts the acquired preliminary environment audio signal to obtain a corresponding preliminary environment audio electric signal;
acquiring a primary external environment sound signal by using a rear cavity MIC;
the rear cavity audio conversion circuit converts the collected preliminary external environment sound signal to obtain a corresponding preliminary external environment sound electric signal;
the processing control module receives the preliminary environment audio frequency electric signal and the preliminary external environment sound electric signal, analyzes and processes the preliminary environment audio frequency volume data and the preliminary external environment sound volume data which are obtained correspondingly, calculates the ratio between the two, and saves the ratio as the basic playing volume data ratio.
